Radio frequency interference device for a high-frequency signal distributor

Abstract: An improved radio-wave insulating device for a high frequency signal distributor, comprising a cover 2a and a case body 3a. The case body 3a is provided with a plurality of protuberances 32a which slightly outsizes the corresponding notches 22a of the cover 2a. Thus when the cover 2a is mounted in place in the case body 3a, a force, which results from the deformation of the protuberances 32a in the notches 22a, is provided parallel to the corresponding side of the cover, thus ensuring a firm engagement between the cover and the case body, without causing the bulging-out of the case body.

Pillow with poisonous gas removing cover

Abstract: A lifesaving pillow uses a flexible and air-permeable antigas sheet member including a poisonous gas removing layer containing an antigas agent for removing poisonous gas and, if necessary, a deodorizing layer containing a deodorizing agent and a smoke filtering layer for filtering smoke as a pillow bag or a detachable pillow cover which is an outside element of the pillow. The lifesaving pillow can be used as an ordinary pillow and further can be utilized as a mask or a self-defensive device having an antigas function by a user putting it over the nose or mouth when a fire occurs.

Self-assembled personalized hidden message device

Abstract: A self-assembled personalized message device including a base substrate with one or more blank areas on which messages can be written; a transparent cover sheet for covering the message areas, a material for adhering the cover sheet to the substrate, and a removable, opaque coating on the cover sheet for obscuring the message area when the cover sheet is adhered to the substrate in which the opaque material is capable of being rubbed off the cover sheet to selectively reveal the message written in the message areas.

Safety cover for vehicle door mechanisms

Abstract: The present invention provides a cover for use in a vehicle such as an automobile for covering door operating elements thereby concealing them from children. The cover is in the form of a rectangular box-like housing which is placed over any upwardly projecting elements such as a locking button, the housing having a bowed front flange which hides such elements as a latching handle on the inside of the door. A rear flange can be inserted between the window and the lower door portion to retain the cover in position.

Magazine advertising device

Abstract: A method and device for advertising goods which includes a booklet having front and back cover sections and a plurality of pages therebetween adapted to bear descriptive material. A plurality of slots partially extend through the pages. Each of the slots is adapted to receive a sample of goods being advertised.

Copies with automatic document feeder

Abstract: A copier selectively operable in a cover plate mode which uses a cover plate and an automatic document feeder (ADF) mode which uses an ADF. After a cover plate mode operation of the copier, a person is inhibited from operating the copier when a condition wherein the cover plate is closed and documents are loaded on a document feed table of the copier is detected.

Traffic control method in mobile communication

Abstract: PURPOSE:To reduce the peak traffic of each zone by varying the zone radius adaptively in response to the traffic. CONSTITUTION:When the traffic of a zone 4 reaches its peak, a traffic monitor 20 detects it to control attenuators 13, 14 to provide a prescribed attenuation. When a prescribed attenuation is fed to the attenuators 13, 14 of the zone 4, the area 21 is reduced as shown in area 21 in figure. Thus, part of the traffic of the zone is decreased as the gone decrease, and the surrounding zones 1, 2 or the like cover the decrease.

Housing for telecommunications unit

Abstract: A telecommunications unit is equipped with a housing (11, 15) which forms a housing cover with two or more housing chambers (19, 20) which are covered by different cover parts (16, 17). A cover part (17) for connectors (13) is easily removed using a simple tool such as a screwdriver while the other cover part (16) for the electric circuit arrangement (12) can only be unlocked in the workshop or by means of a special key-like tool. Thus, the chamber (19) for the circuit arrangement is, when its cover part (16) is closed, secured in accordance with the relevant safety regulations, while the connectors (13) for connection can be made accessible using a tool although their cover is secure against being opened by hand. Similar securing can also be provided on a possible third chamber, for example intended to accommodate mains connection means.

Abstract: An information display device (50), having at least one form printed sliding data card (26A,26B,) portions of which (D) are visible through one or more apertures (36) in the data card cover (32), is made from a preprinted composite paper sheet (20). The information display device can be personalized for use as a direct mail article.

Automatic storage device with anti-intrusion and fire protection devices and size control

Abstract: The vertical and horizontal motions are autonomous and independent. A lock chamber, combined with human presence detections and utilization of an individual cover, provides for a protection against fire and vandalism as well as a size control.

Manufacture information reader

Abstract: PURPOSE:To attain the reading without removing the cover, etc., of a device simply while the power source is turned on by reading the necessary manufacture information from a non-volatile storing means to store the manufacture information with a manufacture information reading means. CONSTITUTION:When the displaying of the manufacture information is instructed to a data reader 70, a reading instruction signal 104 is outputted to ROM 50-53, manufacture information signals 100-103 written beforehand are respectively outputted and latched to registers 60-63. Next, by a scan pulse 105, the latched signal is successively shifted, taken out to a data reader 70 and the taking-out for one step is completed. This is repeated up to the final step, the processing such as arranging and retrieving is executed and displayed at a data display device 71. Thus, without removing the cover, etc., of the device simply and while the power source is turned on, the reading can be executed.

Outdoor automatically renting machine

Abstract: PURPOSE: To obtain an outdoor automatic rental machine by providing a cover opening/closing means, a rental termination detection means and the control means of the cover location of the detection. CONSTITUTION: All the rental operations are terminated and the leaving of a user from a rental machine is detected by a body sensor 5. Based on this detection, a control means 8 controls a cover opening/closing means 4, a cover 2 is moved to the cover to a closing location and the cover 2 covers an operation panel part 3. When the next user inserts a membership card into card reader 7, the control means 8 controls the cover opening/closing means 4 based on this moving and moves the covers 2 to an opening location. Thus, an operation panel 3 is made a usable state. By this constitution, a convenient outdoor automatic rental machine in which water proof and contamination, etc., are surely prevented, the equipments on the roof, etc., is unnecessary and the cover is automatically opened/closed can be obtained.
