Title: Camera
Inventor: MASUDA HIDETOSHI
IPC: G03B17/00
Filed: 1990-08-02
Abstract: PURPOSE:To properly inform the abnormality of a camera to a photographer and to rewind a film already photographed by starting the rewinding of the film only by depressing a photographing button to a photographing position when the abnormality detection signal of a photographing action is outputted. CONSTITUTION:When abnormality occurs in even one action among the photographing actions, an H level is outputted by an abnormal action detection means 5. A signal outputted by the means 5 is outputted to a switch input circuit 1 and an external display means 8. As the result, all of operation buttons except the photographing button 7 among the operation buttons inputted to the input circuit 1 are not detected by a CPU 2 and the photographing action as the camera is not executed at all. When the photographing button 7 is depressed to the photographing position under such a state, both outputs of AND gates 11 and 12 become an L level and the same state that a rewinding button is operated at the time of a normal action is attained. In such a way, when the photographer executes the photographing by operating the photographing button no matter how the action of the camera is abnormal, the rewinding action of the film is started by a film feeding means 6.

Title: Blower motor for car air-conditioner
Inventor: MASUZAWA TOSHIICHI
IPC: H02K5/167
Filed: 1993-08-20
Abstract: PURPOSE:To prevent shortening of service life or generation of abnormal noise due to adhesion of lubricant to a commutator by fixing an oil retaining member and an oil-free member around an oil retaining bearing held by a motor cover while opposing the commutator thereby restraining the lubricant, drained out of the bearing, from scattering outward. CONSTITUTION:One of two bearings for supporting a rotor 9 is covered, on the outer peripheral part thereof, with an oil retaining felt 2 and an oil-free felt 5. Consequently, the lubricant drained from the outer peripheral part of the first bearing 1 during rotation of a shaft 3 is entirely absorbed by the oil- free felt 5. Consequently, the lubricant drained out of the bearing is restrained from scattering outward and thereby shortening of service life and generation of abnormal noise due to adhesion of lubricant to a commutator can be prevented.

Title: Switching power unit
Inventor: NAKAGOME HIDEFUMI
IPC: H02M3/338
Filed: 1987-08-21
Abstract: PURPOSE:To reduce a power loss so as to improve overall efficiency by specifying the inductance characteristic of a primary winding in a ringing choke converter transformer. CONSTITUTION:A switching power supply circuit, which uses a ringing choke converter circuit serving as the constant-voltage regulated power supply, is constituted by connecting a switching transistor(Tr)Q1 an input capacitor C1 to the primary winding side of a transformer T further connecting an output resistor R2, a rectifier D, and a smoothing capacitor C2 to the secondary winding side. In order to obtain the constant-voltage regulation, feedback amplifier circuits FBCI-II are provided. Here the transformer T sets its inductance L in such a manner as to increase when a primary winding current Icp decreases. This reduces the on-time of the transistor TrQ1 and increases frequency when a load condition decreases, by its increase can be suppressed because of large inductance L.
