Title: Overwrite system for magneto-optical disk
Inventor: IZUMI HARUHIKO
IPC: G11B5/02
Filed: 1988-06-16
Abstract: PURPOSE:To realize a writing action while carrying out an erasing action by forming a gap between two spots formed by a 2-beam optical head. CONSTITUTION:A 2-beam optical head 5 emitts a leading erasing beam 6 and a subsequent recording beam 7 to the tracks of a magneto-optical recording medium 4 exclusive for single-side recording jobs. A magnetic field generating means 8 which produces an erasing external magnetic field is set with no contact to the opposite side of the medium 4 corresponding to the surface irradiated by the beam 6. Then the means 8 forms a closed magnetic path having a prescribed gap 9. The head 5 emitts the beam 6 to an area where the leaked magnetic flux of the line of magnetic force produced at one of two magnetic poles opposite to the gap 9 passes through the medium 4. At the same time, the head 5 emitts the beam 7 to an area where the leaked magnetic flux passes through the medium 4 in the opposite direction since said magnetic lux forms a closed magnetic pathe with the other magnetic pole. Thus both the erasing and writing actions are carried out at one time.

Title: Semiconductor circuit
Inventor: NANBU HIROAKI
IPC: G11C11/414
Filed: 1984-07-20
Abstract: PURPOSE:To enable to handle signals of large amplitude in a semiconductor circuit provided with a current switching circuit, by generating specified three kinds of reference potential. CONSTITUTION:When taking in an input signal VIN1, it is enough to generate intermediate potential VBB(M) between high potential VIN1(H) and low potential VIN1(L) of the input signal. At this time, if the input signal is VIN1(H), a transistor TRQ1 becomes on, and if VIN1(L), TRQ2 becomes on. When the input signal is not to be taken in, reference potential VBB(L) lower than low potential VIN1(L) of the input signal or reference potential VBB(H) higher than high potential VIN1(H) is to be generated. Under this state, TRQ1 or Q2 always become on regardless of the level of the input signal VIN1. Thus, signals of large amplitude can be handled.

Title: Pulse width modulation load controller
Inventor: SOMIYA MASAHITO
IPC: H02P5/00
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a pulse width modulation load controller capable of reducing a power source voltage change as compared with the prior art. SOLUTION: In the case of PWM controlling a plurality of loads 1 to 4 by a PWM(pulse width modulation) signal, the pulses of pulse width modulation signals PWM1 to PWM4 for driving the loads 1 to 4 are dispersed substantially at equal intervals by, for example, deviating the phase at 90 degrees by a timing control circuit 21. Thus, the superpositions of the pulses of the signals PWM1 to PWM4 are reduced, and superposition periods are dispersed. When the pulse widths are small, the period that all the pulses of the signals PWM1 to PWM4 are not excited (a common pulse interval period) is finely segmented by the pulses of the PWM signals. The change of the current flowing from a battery is enhanced in frequency, and the change is reduced.  On the other hand, the impedances of a power source system or the loads have electrostatic capacity or inductance and hence the discharging current of the battery is not continuously discharged for a long period or paused for discharging, but can be easily averaged.

Title: Shock absorber
Inventor: TOMOYA SHIGERU
IPC: F16F15/067
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent such occurrence that an apparatus attaching mount is fallen down sideways so that apparatus positioning accuracy against a base can be enhanced, by attaching on the base a slide table by which the apparatus attaching mount can be guided in the direction of the axial line of a spring. SOLUTION: A slide table 2 by which an apparatus attaching mount 3 is guided in the direction of the axial line of a spring 4 is equipped with an outside table element 2a, an inside table element 2b and a ball bearing between the elements 2a, 2b. Hereby, even though a shock is applied to the apparatus attaching mount 3 from the outside through an observing apparatus, the apparatus attaching mount 3 is guided in the same direction by the inside table element 2b moved only in a vertical direction against the outside table element 2a through the ball bearing. Therefore, the shock applied from the outside to the observing apparatus is transmitted to the apparatus attaching mount 3, and a part of the shock is adsorled by the spring 4 displaced in a base 1.

Title: Inspection device using nuclear magnetic resonance

Filed: 1989-06-14
Abstract: PURPOSE:To obtain an orthogonal crossing position detecting probe, in which orthogonal crossing adjustment can be performed easily in a short time further with no change or resonance frequencies of two coils, by dividing a wing part and an arm part and providing an electric connection part between the wing part and the arm part constituted of a conductor. CONSTITUTION:In the case of moving an arm part 204B in the direction of an electric connection part 25, one conductor of the electric connection part 25 is removed and inserted to an electric connection part 26, and a sum of thickness of the conductor is changed by right-left moving the arm part 204B. When this operation is simultaneously performed in the upper and lower electric connection parts, only an arm can be moved without moving a wing in both sides of the arm. Accordingly, the arm part 204B can be moved with a wing part 228 left as fixed by dividing the wing part 228 and the arm part 204B. Since the wing part 228, not related to orthogonal crossing adjustment, can be moved, a value of capacitance, constituted of a guard ring 26 and the wing part 228, can be always held to a fixed value. That is, by changing the capacity of the capacitance constituted of the guard ring and the wing part, unbalance is generated in right and left of the arm part, so that execution orthogonal crossing adjustment is made difficult.

Abstract: PURPOSE:To reduce the circuit scale and to attain a high speed operation. CONSTITUTION:Outputs Q0-Q15 of a stream register 2 are given to a Huffman register 11 and outputs Q16-Q26 are given to an additional bit register 12. The Huffman register 11 and the additional bit register 12 load the output of the stream register 2 based on a clock CK2 generated in a timing outputted when the head bit of a Huffman code is outputted from the output Q15. Thus, the Huffman register 11 loads a Huffman code in a prescribed word and the additional bit register 12 obtains the additional bit of a preceding word in an LSB justification. A Huffman decoding section 4 decodes a Huffman code. When an additional bit of a prescribed word is outputted from the additional bit register 12, a decoding output of a prescribed word is outputted from the Huffman decoding section 4 and an additional bit processing section 6 decodes the additional bit without a delay.
