Title: Zero point position detector
Inventor: WATANABE NORITO
IPC: G01D5/36
Filed: 1993-05-13
Abstract: PURPOSE:To allow easy formation of a zero point detection pattern without requiring any etching by forming the zero point detection pattern or the periphery thereof into a diffused surface. CONSTITUTION:First and second light beams 1, 2 are partially reflected on a half mirror 3 and impinge normally on a scale 4. The scale 4 moves in the arrow direction and when diffused surfaces 51, 52 approach points P1, P2, the diffused surface 51 arrives at the position P1 at first and thereby the light beam 1 reflected on a reflective surface 7a is scattered on the diffused surface 51 thus reducing the reflected light 1' impinging on a light receiving element S1. When the diffused surface 52 arrives at the position P2, the light beam 2 is scattered on the diffused surface 52 thus reducing the reflected light impinging on an element S2. Signals from the elements S1, S2 have a phase shift and delivered on a signal line L to a zero point detecting means 6. The means 6 generates a signal representative of the zero point of scale 4 immediately upon matching of input signal level thus detecting the zero point of the scale 4.

Title: Connection system for variable capacity element
Inventor: MORI SEIJI
IPC: H03H5/12
Filed: 1980-09-29
Abstract: PURPOSE:To prevent completely the variance of the capacity due to the influence of a signal voltage, by adopting a connection system where to varicap diodes are constituted in parallel with polarities opposite to each other for a processing signal voltage. CONSTITUTION:If DC blocking capacitors 7 and 8 are so selected that their reactance is small sufficiently for a processing signal frequency, processing signal voltages applied to varicap diodes IA and IB are equal to each other, and polarities of the variance of the capacity are opposite to each other because varicap diodes IA and IB are connected in directions opposite to each other. When the combined capacity of varicap diodes IA and IB and a control signal voltage are denoted as C0 and V0 respectively, equation C0=f(V0+ or -DELTAV)+f(V0 DELTAV)=f(V0) is true for the processing frequency. In respect to the function f(V), the capacity is changed linearly approximately for the applied voltage, and f(V)=alpha+beta is true. alpha and beta are constants, and varicap diodes which have such characteristics that capacities are changed linearly approximately for the applied voltage are used as IA and IB, thereby preventing the variance of the capacity due to the influence of the processing signal voltage.

Title: Power steering
Inventor: HACHISUGA HIROSHI
IPC: B62D5/083
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain preset force even in case of being assembled with slight dislocation in the rotating direction relative positions of an input shaft and an output shaft by providing the input shaft with first permanent magnets, and providing the output shaft with second permanent magnets so that the first and second permanent magnets attract each other. SOLUTION: A first permanent magnet 23 is rigidly fixed to the center part of a circular arc part 131 of an input shaft 13, and a second permanent magnet 24 is rigidly fixed into a hole 15a of an output shaft, 15 in such a way as to attract each other. In the same way, first and second permanent magnets 23', 24' are arranged at the center part of the other circular arc part 131'. When steering wheel operation is very small, the input shaft 13 is held by the attractive force of these permanent magnets, and the relative rotation to the output shaft is regulated. As steering wheel operation becomes larger, a dislocation in a rotating direction becomes large, so that the attractive force is rapidly lowered, and the steering torque is rapidly reduced.  Preset force can therefore be obtained even in case of being assembled with slight dislocation in the rotating direction relative positions of the input and output shafts 13, 15.

Title: Record player
Inventor: AKITA ISAO
IPC: G01P3/42
Filed: 1979-10-20
Abstract: PURPOSE:To make easy accurate adjustment of the rotating speed of a turn table, by detecting the rotating speed of the turn table, comparing the detected speed signal with the reference speed signal by a phase comparator, converting the output phase difference signal into a voltage and controlling the illumination of the display element of a level indicator. CONSTITUTION:When a turn table rotates with the drive of a motor, the detected speed signal in proportional to the rotating speed of the motor is output from a frequency generator 4 and it is input to a phase comparator 6 via a waveform rectifier 5. On the other hand, the reference speed signal obtained through the frequency division of the output signal of a reference oscillator is input to the comparator 6 and the phase difference with the detected signal is compared. If the phase of the detected speed signal advances to that of the reference speed signal, the phase difference signal is output from an output terminal 01 and if delayed, then from a terminal 02. The output is compared with the reference voltage 10 at comparators 9, 11 via LPFs 7, 8, allowing to illuminate a plurality of elements of a display device 12 according to the output level. Accordingly, accurate adjustment of the rotating speed can be made easy.

IPC: H04N5/335
Filed: 1980-10-01
Abstract: PURPOSE:To prevent the production of noise component due to static capacitance coupling and to increase carrying speed, by forming a plurality of impurity layers with opposite conduction type on a conductive type semiconductor substrate through completed depletion. CONSTITUTION:A plurality of N type impurity layers 30 are formed on a P type semiconductor substrate 8 through complete depletion. Broken lines 37 are surface potential under carrying gate when a carrying gate 10 is opened and signal electrons are carried toward the arrow 41. Since the potential 35 is completely in depletion, the signal charge to be stored in present in a potential well only formed under a storage electrode 9. On the other hand, in opening the carrying gate 10, since the time carried with signal electrons is almost proportional to the square of channel length of stored region, the speed is increased by the share of Ln. Since the N type impurity layer is completely in depletion, no potentials 33, 34 are varied through the capacitive coupling of carrying gate.
