Air conditioning apparatus
TLDR
In this paper, an air flow rate sensor and throttle valve are provided in a control duct between a supply chamber utilizing double ceilings and the air diffusers in the supply chamber, which can be equalized or can be set to the desired values.Abstract:
An air flow rate sensor and throttle valve which controls the opening of a duct in accordance with the detection signals from the air flow rate sensor are provided in a control duct between a supply chamber utilizing double ceilings and the air diffusers in the supply chamber. The quantities of air fed from the respective air diffusers can be equalized or can be set to the desired values. In this case, since the air blowing can be automatically controlled for each diffuser, it is not necessary to individually adjust the quantities of air for the respective air diffusers after the installation of the air conditioner, thereby eliminating the adjusting works of the air diffusers.read more

Flow control apparatus and air filters
TL;DR: In this article, a high efficiency air filter system of the type used in clean rooms and the like, and having a sliding plate valve associated with each filter, is described, where a highly viscous, non-evaporating fluid is positioned between the plates to prevent the air from flowing laterally between them, whereby the volume of air flow may be accurately controlled over the entire area of the clean room as well as the full area of each filter.
Patent
Central air conditioning equipment
TL;DR: In this article, a central air conditioning equipment which performs air conditioning for a plurality of rooms, comprises a terminal air quantity control unit which is installed in order to communicate with each room and which controls the quantity of the air stream which is distributed to each room through a duct, and an air quantity controller device, attached to an air conditioner, which controls a blower to reduce the blown air quantity until at least one of dampers reaches a first position to allow air flow when all of the dampers are not in the first position.
Patent
Color receiving tube
TL;DR: In this article, the authors proposed to compensate the dynamic convergence error in arc shape due to the sealing error of electronic gun and the assembling error of deflection coil by providing magnets around the external circumference of the neck part between the tip of the electronic firearm and the deflection center of a deflection cone.
