Title: Atmospheric air intake device of unit air conditioner
Inventor: ASAI TETSUO
IPC: F24F1/02
Filed: 1987-04-08
Abstract: PURPOSE:To obtain a predetermined quantity of atmospheric air intake and a predetermined quantity of indoor air discharged within a limit value and to perform air conditioning using only circulating air when an atmospheric air pressure more than the allowable value is applied, by providing a damper plate on the lee side of a suction duct, and automatically adjusting the opening degree of the damper in accordance with the atmospheric air pressure thereby to set the allowable pressure value of a buffer. CONSTITUTION:When the atmospheric air pressure becomes high by the action of a buffer 30 provided in a damper plate 31, the damper plate 31 is pushed in the direction of blocking a ventilation opening, and, at the same time, moves toward the direction of blocking an indoor air discharge port 32. An increment of the atmospheric air intake quantity due to the atmospheric air pressure and a decrement of the atmospheric air intake quantity due to the narrowing of the gap, offset each other to keep the atmospheric air intake quantity at a predetermined value. On the other hand, with respect to the discharge of indoor air, since the quantity of indoor air discharged tends to be similarly kept at a predetermined values by the action of the damper plate 31, the balance of the indoor ventilation quantity can be secured as a result. At the time of a strong air flow, when its pressure exceeds the allowable pressure of a buffer 30, the damper plate 31 comes into collision with a stopper 45, and the air flow passage is put into a fully closed state so that the ventilation is suspended, and air conditioning due to only indoor circulating air is conducted.

Title: Motor braking circuit
IPC: H02P6/24
Filed: 1992-03-10
Abstract: PURPOSE:To brake a motor, particularly a sensorless and brushless DC motor stably and effectively. CONSTITUTION:The comparison output waveform of a voltage waveform appearing in the terminal of a stator coil with a reference potential (the middle- point potential of the coil) is edge-detected and a reverse-drive current for braking a motor actively is applied on the basis of the edge-detected output. In this case, the detection of edge is selectively performed within the non-power- application period of the stator coil. Thus, even if the terminal voltage waveform of the stator coil is largely disturbed by the application of the reverse-drive current, the application phase of the reverse-drive current can be accurately controlled without being affected by such disturbance and on the basis of induced voltage appearing in the stator coil by the rotation of the motor.

Title: Electromagnet
Inventor: KAWAGUCHI KATSUHIKO
IPC: H01F7/14
Filed: 1983-05-19
Abstract: PURPOSE:To compactly form the structure with which an armature will be returned as well as to eliminate the adverse effect caused by residual magnetism by a method wherein a compression spring to be used for return of armature is attached to the space located at the part opposing to the armature of a core. CONSTITUTION:The armature 2 is attracted while a spring 10 is being compressed when a current is applied to a coil 5. Residual magnetism is left on the attraction surface 6a even after the current applied to the coil 5 is cut off, but by the formation of gap G, the armature 2 quickly returns to its original position by the force of the compression spring. As the compression spring 10 is made of non-magnetic material, it is separated from the core 6 in an excellent manner. As a result, the space required is reduced, the structure can be compactly formed. Also, the stabilization of the compression spring can be contrived by the formation of a recessed part on the core, and the separation of the armature from the core is excellently performed even when residual magnetism is generated, thereby enabling to perform a high speed movement.
