The object of the present invention is to provide an optical recording medium which includes a substrate, a first information layer and a second information layer, the first information layer and the second information layer are disposed on the substrate through an intermediate layer in a laminar structure; recording and reproducing is performed on each of the two information layers by laser beam irradiation from the first information layer side; the second information layer is provided with at least a reflective layer, a dielectric layer, and a second dye recording layer formed in this order; and the dielectric layer is formed from any one of materials selected from the group consisting of oxides, nitrides, sulfides, carbides or mixtures thereof from any one of elements which are not same as metal elements and semi-metal elements used for forming the reflective layer.

Optical Recording Medium

The present invention relates to a fiber-reinforced composite material and a method for manufacturing the same, and also relates to a transparent multilayered sheet, a circuit board, and an optical waveguide.

An keyboard assembly for an electronic musical instrument is mainly constructed by a key frame, a key, a key switch and an assembly guide member. A fixing portion of the key is supported by the key frame such that a front portion of the key can be freely rotated up and down. An actuator is attached to and projected downward from a lower side of the key. The key switch (or a key-depression sensor) has an elastic projecting portion at its upper end. This key switch is provided on the key frame and is driven by the actuator, which depresses down the elastic projecting portion of the key switch when the key is depressed down. The assembly guide member guides the key when the key is moved in an assembling direction (i.e., a longitudinal direction of the key) in order to carry out an assembling operation to assemble the key and the key frame together. Herein, the key is guided by the assembly guide member in such a manner that the actuator does not come in contact with the key switch during the assembling operation. Thus, the key switch is not damaged at all by the actuator during the assembling operation of the keyboard.

An underwater sensor device comprises a submersible housing including one or more housing components, one or more sensors for monitoring and collecting water characteristics, a controller for controlling operations of the one or more sensors and an graphical user interface mounted to the housing that displays the water environmental data. The housing defines a channel that extends through one of the housing components, and at least one of the sensors is mounted to the housing and extends into the channel. The controller is disposed within the housing and is operatively connected to the one or more sensors.

A processing apparatus for fluid with a simple structure, high productivity, ability of precise dispersion, emulsification and grinding, is provided. The apparatus of the present invention comprises at least two processing faces of a first face and a second face, both of which are arranged in a tight-closed passage, and positioned opposite to each other to constitute part of said passage, and a contact pressure applying mechanism for putting both faces 1, 2 into closed contact with each other, wherein the rotation of the second processing face 2 in respect of the first processing face 1 may cause dispersion or emulsification of the fluid to be processed between both processing faces 1, 2. The first and second processing faces 1, 2 are placed in closed contact with or adjacent to each other by means of said contact pressure applying mechanism, and the fluid to be processed is actuated by said rotation to pass between the first and second processing faces 1, 2, as it is forming fluid films between said processing faces 1, 2, so that said fluid will be emulsified or dispersed to a desired extent.

PURPOSE:To prevent the generation of the oxidation and change of properties of food particularly at the time of pulverizing of the food and to prevent the explosion at pulverizing a metal into powder by pulverizing a matter between grinding wheels held in a vacuum or anaerobic gaseous atmosphere and further, storing the matter in the continuous atmosphere. CONSTITUTION:Raw materials are supplied between the stationary grinding wheel (a) existing in the vacuum or anaerobic gaseous atmosphere and the rotary grinding wheel (b) rotating opposite thereto, by which the raw materials are pulverized in the vacuum or anaerobic gaseous atmosphere. The materials are discharged simultaneously from between the two grinding wheels and are stored in a storage tank 28 in the atmosphere continuous therewith. The pasty food materials of the food with which the oxidation and the change of properties are vigorous are inexpensively produced without having such deterioration in properties and further, the dry grinding down into powder having the danger of explosion is extremely inexpensively executed.

PURPOSE:To prepare a soya milk product free from the characteristic unagreeable odor of bean juice easily, by immersing dried soybeans in hot water for a short time, heating the swollen soybeans with hot steam to inactivate the sporal enzyme and boil the swollen soybeans, and grinding the boiled soybeans. CONSTITUTION:The shower head 20 to eject hot water is attached to the top of the hopper 12 for supplying soybeans, and the cylindrical jacket 17 to blast steam into the hopper 12 is attached around the lower circumference of the hopper 12. The soybean grinding chamber 1 is positioned below the jacket 17 interposing a hot-water ejection chamber 23, and the chamber 1 is furnished with the stationary grindstone (a) and the rotary grindstone (b), and with a ring- shaped steam jacket 11 at the circumference of the chamber 1. The stirring blade 22 and the metering screw 24 are placed in the hopper 12. The dried soybeans are immersed in hot water for a short time, the swollen soybeans are heated with hot steam to inactivate the sporal enzyme and at the same time to boil the beans with hot steam, and the heat-treated soybeans are ground in a chamber 1 having hot atmosphere. Accordingly, a soya milk product free from the characteristic odor of bean juice can be prepared easily.
