Title: Silencer
Inventor: NAGAYASU KATSUYOSHI
IPC: G10K11/178
Filed: 1988-03-30
Abstract: PURPOSE:To surely make a radiated tone from a cavity silent by controlling a control sounding device by a time waveform signal being the result of each frequency component analyzed by a frequency analyzer processed by using a coefficient of a corresponding frequency read from a storage device and synthesized. CONSTITUTION:A sound generated by a sound source 13 is converted into an electric signal by a microphone 15, amplified by an amplifier 17, converted into a digital signal by an A/D converter 18 and the frequency is analyzed by a high speed frequency analyzer 19. On the other hand, a phase and a multiple factor in response to the sound wave mode pattern with respect to each frequency of the cavity 12 are stored in a storage device 20 and when each frequency component is outputted to the high speed frequency analyzer 19, an arithmetic unit 21 multiples the coefficient and the signal is restored to the time waveform and the result is given to a speaker 19 via a D/A converter 22 and an amplifier 23. Thus, the sound from a sound source 13 and a sound from the speaker 16 are cancelled completely at a control object point 14. Thus, the sound is surely erased.

Title: Reception system for spread spectrum signal
Inventor: NAITO TOSHIKATSU
IPC: H04B1/7115
Filed: 1987-03-27
Abstract: PURPOSE:To keep the S/N to >=0dB over a wide range of a disturbance wave level and a desired wave level by weighting each output of an array antenna, obtaining all added outputs and subtracted outputs, synthesizing them while making the level of the both nearly equal to each other and inputting the result to a spread spectrum receiver. CONSTITUTION:Outputs of omnidirectional antenna elements 1, 1' arranged at a prescribed interval are branched into weighting circuits 2, 2' and weight control circuits 3, 3' based on the PI (power inversion)algorithm, outputs of the control circuits 3, 3' are added by an adder 4 while the amplitude and phase are controlled by the weighting circuits 2, 2', and subtracted by a subtractor 5. The signals are amplified to be in nearly equal level by automatic gain control amplifiers 6, 6', synthesized by an adder 7 and inputted to a spread spectrum receiver 8. Through the constitution above, a signal with a smaller level among the signal received by the antenna is outputted while its level is increased and a signal with a larger level is outputted while its level is decreased from the adder 4, and a signal received by the antenna larger in level is increased at the subtractor 5.

Title: Electrostatic-type deflector for charged particle rays
Inventor: KURODA KATSUHIRO
IPC: H01J37/153
Filed: 1982-05-07
Abstract: PURPOSE:To obtain a charged-particle optical system which has a reduced size and a decreased aberration by integrating an electrostatic-type deflector with an astignatism corrector. CONSTITUTION:4N (N=2-6) electrodes are located symmetrical relative to an axis, and a deflecting voltage (Vx, Vy), an astigmatism-correcting voltage (Va, Vb) or a voltage which is the sum of the above voltages is applied to each of the 4N electrodes. Application of a deflecting voltage to each electrode is performed in order to remove a 4-times symmetrical deflectional aberration (named a rotation uncharged system). By applying an astigmatism-correcting voltage in addition to the deflecting voltage to each electrode as indicated in the figures, the astigmatism of charged particle rays can be corrected without disturbing a deflecting electric field. As a result, a deflector and an astigmatism corrector can be integrated with one another and a location space can be saved, thus the aberration of the entire optical system which suppresses its own deflectional aberration is reduced. In addition, since the deflector is the electrostatic type, it is suitable for high speed deflection and high speed correction as well compared to that of the magnetic field type.

Title: Coin feeding machine
Inventor: KAWAMURA YASUHIKO
IPC: G07F5/22
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To easily attain visual recognition of the display screen part of a counter by providing a light transmissive masking panel on the surface of a easing, holding the counter at a position confronting the masking panel in the casing, and illuminating the display screen part of the counter with a light. SOLUTION: A light 12 is usually turned off for the counter device of a game machine 1, and a half mirror 11 is recognized as a mere colored panel since the inside of the mirror 11 is dark. Thus the display screen part 9 of an internal counter 10 is invisible from the outside. Then a switch of a casing 4 is pushed to turn on the light 12 when a coin collector checks whether he should collect coins. Thus the periphery of the counter 10 surrounded by a support member becomes bright and the coin collector can view the part 9 of the counter 10 via the the mirror 11. When the coin collector visually recognizes the part 9 via the mirror 11 and confirms an adequate amount of coins stored, he unlocks a cashbox and collects the coins there.

Title: Drive circuit for inductive load
Inventor: ONUKI RYUICHI
IPC: H02P8/00
Filed: 1986-03-31
Abstract: PURPOSE:To keep the current flowing to the load within the specified limits for any input of chopping frequency driving signal. CONSTITUTION:A current control circuit 2 changes the output in accordance with the frequency of chopping actuation. In a proper chopping actuation, the voltage VR2 is inputted to the terminal of a comparator IC3 which is decided by the partial pressure ratio between resistances R3 and R2 connected in parallel and a resistance R4 connected in series. In the meantime, when the current value is below n-times in which it is impossible to actuate the chopping, the voltage inputted to the comparator IC3 is decided by the partial resistances R3 and R2, so that the value will rise as compared with the case in the abovementioned chopping actuation. On this account, when it is impossible to actuate the chopping by high speed operation, the increase of supply current to a coil L is ensured and the sufficient torque can be obtained without fail.

Title: Power supply controller
Inventor: NAGAHIRA JOJI
IPC: H02M3/28
Filed: 1990-03-27
Abstract: PURPOSE:To perform constant voltage or constant current control through a relatively simple constitution and to facilitate digital integration of circuit by controlling the output of an oscillator according to the digital output from a comparing means. CONSTITUTION:A comparator 1 compares the voltage across a resistor R1 passed through a lowpass filter 2 with a control reference voltage E2. When a low current flows through a load, output of the comparator 1 goes High and the output from a rectangular wave oscillator 3 is fed to a transistor Q1 thus increasing the output voltage to be fed to the load. Upon increase of the output voltage, an increased current flows through the resistor RL and the output of the comparator 1 goes Low and thereby the base of the transistor Q1 goes Low thus lowering the output voltage to be fed to the load.
