Title: Jacket for floppy disk
Inventor: HARADA SHINJI
IPC: G11B23/033
Filed: 1982-12-13
Abstract: PURPOSE:To prevent the deformation of a jacket such as folding and bending due to a failure in handling and destruction, etc., by providing a metallic rod and a synthetic resin rod which have strength entirely or partially to the circumference of the jacket. CONSTITUTION:Notches 4 are provided at several positions of the circumferential part of the jacket body 3 which has a center hole 1 and consists of sheets of resin, etc., while containing a disk 2. Then, the metallic rod (or synthetic resin rod) 5 which has strength enough to withstand relatively rough handling is provided to the circumference of the jacket body 3 while inserted into those notch parts 4 to assemble the jacket. In this case, a metallic rod made of stainless steel having, for example, a 1mm. diameter is used. At this time, stress due to bending force concentrates to near a head window 10 which should be handled most carefully and is relatively weak, and this part exerts large influence upon the rotation of the disk, so the reinforcement of this part is important.

Title: Outer mirror control device
Inventor: KONDO OSAMU
IPC: B60R1/06
Filed: 1992-08-18
Abstract: PURPOSE:To provide an outer mirror control device which moves an outer mirror in the direction adequate to the backward operation of the car only when a driver wants to do so. CONSTITUTION:The direction of an outer mirror is converted only when a driver operates an autoswitch in order to convert the direction of the outer mirror (S101 and 102), after it is decided that a shift lever is moved to the backward position (S100). As a result, an error operation to convert the direction of the mirror, when the driver does not want to convert the direction of the mirror even when he carries out the backward operation, can be prevented.

Title: Resolver
Inventor: SAKAI KAZUTO
IPC: G01D5/245
Filed: 1987-09-03
Abstract: PURPOSE:To miniaturize and to increase the degree of accuracy by compensating a manufacturing error by using the first to third resistances each for phase balance fine adjustment, permeance quantity adjustment and for excitation impedance balance respectively. CONSTITUTION:The first resistance R1 of low resistance value for phase balance fine adjustment and the second resistance R2 to adjust equivalently permeance quantity are connected in series to two excitation windings (for example, Ua1 and Ua2) connected in series of each phase, and the third resistance R3 for excitation impedance adjustment is connected in parallel to the first and the second resistance. The magnetic field is formed by excitation winding, and when a rotor rotates, the permeance due to the rotor teeth varies with almost sine wave function against the rotation angle. The phase modulated signal voltage is obtained by output winding. Accordingly, in spite of the miniaturization, the balance of each phase is improved, and the influence of the work and assembly errors can be suppressed to the minimum.

Title: Transmitting output control circuit
Inventor: AIHARA YUKICHI
IPC: H03G3/30
Filed: 1990-08-20
Abstract: PURPOSE:To control transmitting outputs at a high speed over a very wide transmitting output level range by fetching part of transmitting outputs by means of a directional coupler and inputting the part of the outputs to a comparison error amplifier for negative feedback control after the part of outputs is passed through a variable high-frequency attenuator and logarithmic or nonlinear amplifier. CONSTITUTION:Part of transmitting outputs outputted from a transmitting power amplifier circuit 2 is fetched by means of a directional coupler 3 and detected by a detection circuit 4 after passing through a variable attenuation circuit 6 and nonlinear amplifier 7. Since the detecting value of the circuit 4 drops and the transmitting outputs apparently decrease when the attenuating quantity increases, a negative feedback loop acts to increase the transmitting outputs. The nonlinear amplifier 7 expands the dynamic range of the detecting characteristic of the circuit 4. Therefore, transmitting burst outputs can be relatively easily controlled with high accuracy over a wide dynamic range by not relying only on the expansion of the dynamic range of the detection circuit 4, but using the variable attenuator 6 also.
