Title: Automatic linearity adjusting circuit
Inventor: MATSUMOTO YOSHIAKI
IPC: H03M1/10
Filed: 1988-06-17
Abstract: PURPOSE:To adjust the linearity of an A/D converter automatically and to attain the A/D conversion with the best linearity at all times by biasing an analog input signal of the A/D converter based on the probability of appearance to a specific bit pattern being an output of the A/D converter. CONSTITUTION:Pattern detection circuits 3-5 connecting to the output of the A/D converter 2 detect respectively bit patterns 0111...1, 1,000...0, 100...01 of a digital signal outputted from the A/D converter 2 and outputs a prescribed signal. Integration circuits 6-8 integrate and output a prescribed signal outputted from the pattern detection circuits 3-5. Then a voltage generating circuit 9 is controlled by the result of integration of the integration circuits 6-8 and outputs a DC voltage in response to the integration value. Moreover, the switch circuit 10 is set when the MSB(most significant bit) of the output digital signal of the A/D converter 2 is, e.g., logical 1 (reset when logical '0'), and a DC voltage from the voltage generating circuit 9 is outputted to an adder circuit 1. Thus, the A/D conversion is attained with the best linearity at all times.

Title: Control device for electrically operated vehicle mirror
Inventor: KISHIMOTO YUUJI
IPC: B60R1/06
Filed: 1982-08-25
Abstract: PURPOSE:To enable an electrically actuated mirror to be returned to an arbitrary memorized attitude with a simple operation, by counting, with the use of a counter, a shift in the attitude of the mirror, and by reversely counting the value on the counter down to its initial value in order to return the mirror. CONSTITUTION:When the contacts 17a, 17b of a switch 17 with respect to a counter 12 are electrically connected together, the counter 12 is reset by means of the output of a fourth NAND logic element 19. Therefore, the counter 12 memorizes the attitude of a mirror upon the switch 17 being turned on, as a zero initial count value, and thereafter, counts the rotational number of a motor 5 which has been required to the control of the attitude of the mirror. When terminals 8a, 8b in a switch are electrically disconnected from each other, the mirror may be returned to its memorized attitude at once. Since the control is carried out by detecting the rotational number of the motor 5, the accurate returning may be made with no affection of voltage variations in a battery 7.

Title: Burning level indicating device for kerosene burning apparatus
Inventor: OSAWA NORIO
IPC: F23D3/28
Filed: 1989-06-12
Abstract: PURPOSE:To make it unnecessary to use a burning level indicator that is far larger than the indicator slot and reduce the size of the support structure for the burning level indicator and its storage space by so designing that the travel of the burning level indicator relative to the travel of the operating lever is greatly reduced in the ignition operation range. CONSTITUTION:The travel of the burning level indicator 31 relative to the travel of the operating lever 20 is designed to be greatly reduced in the ignition operation range. Therefore, even when the burning level indicator 31 is linked to the single operating lever 20 whose movement range spans the wick height adjusting range and the ignition operation range, the travel of the burning level indicator 31 within the ignition operation range becomes very small. This constitution makes it unnecessary to use a burning level indicator 31 that is far larger than the indicator slot and reduces the size of the support structure 30 for the burning level indicator 31 and its storage space.

Title: Time counting method of computer system
Inventor: MAKINO TETSUO
IPC: G06F1/14
Filed: 1982-08-30
Abstract: PURPOSE:To attain time count information of a precision higher than that of an oscillating circuit, by comparing time count information of the counter output and another high-precision time count information with each other and correcting the set value, which a central processing unit gives to the counter, so that the error is eliminated. CONSTITUTION:A CPU 16 sends a signal from a data output terminal 18 to an input terminal 19 of a counter 13 and sets the counter 13 so that the output of the counter 13 has an interrupted frequency convenient for the CPU 16. The counter 13 outputs the output from an output terminal 15 at intervals of a certain period to interrupt the CPU 16. The CPU 16 uses this interrupt signal as time count information and reports it to the operator. The operator compares an independently prepared very accurate clock with time information reported from the CPU 16 to correct the set value which the CPU16 set to the counter 13. By this correction, time count information of the CPU16 has a precision higher than that of a quartz oscillating circuit 11.

Title: Scanning frequency converter
Inventor: YANAGISAWA TAKESHI
IPC: H04N7/01
Filed: 1988-06-17
Abstract: PURPOSE:To display a video signal with a different scanning frequency for both horizontal and vertical directions on the screen by inhibiting the readout only when an address selector receives a synchronizing signal of the 2nd video signal. CONSTITUTION:When a synchronizing signal is inputted from a synchronizing separator circuit 4 to an address selector 7, the address selector 7 outputs a vertical line readout address to a memory 6 with priority and withdraws an output while storing the data from an A/D converter 1 to an FIFO memory 8. Then the memory 6 receiving the readout address reads out a data written in a corresponding address according to a horizontal picture element readout clock and a video signal is generated via a D/A converter 9. Thus, the video signal is displayed within the period of the horizontal synchronizing signal of the 2nd video signal and within the horizontal/vertical period designated in the period of the vertical synchronizing signal. Thus, the 1st video signal is displayed on the pattern of the 2nd video signal with a different scanning frequency.

Filed: 1986-06-27
Abstract: PURPOSE:To prevent a soft error from being produced by alpha rays by forming a p-n junction semiconductor layer between both the collector layer and SBD portion of an HBT and a substrate. CONSTITUTION:After Si ions are selectively implanted in a semiinsulative GaAs substrate 10 by using a photo resist as a mask, annealing is performed and the Si ions are activated to form an n-type buried layer 9. Then, Be ions are selectively implanted in a position wherein Si ions are implanted by using the photo resist and annealing is performed to activate the Be ions and form a P-type buried layer 8 whereby a p-n junction is formed. The layers 8 and 9 are so formed as to cover at least the n-type collector layer 12 of an HBT 100, an SBD 101 and the connecting portion of the collector layer 12 and the SBD 101 in a planer fashion.

Title: Speaker system
Inventor: SATO KAZUHIDE
IPC: H04R1/30
Filed: 1987-06-16
Abstract: PURPOSE:To obtain a frequency characteristic flat even if in case of a short horn or acoustic tube by providing a horn wall of sound absorption material inside the horn or the acoustic tube disposed in front of a diaphragm in a manner that the area of the horn wall is small in front of the diaphragm but gradually increases as approaching the opening part. CONSTITUTION:Inside the acousitic tube 3, the horn wall whose area is small in front of the diaphragm but increase as coming closed to the opening part is formed with an acoustic absorption material 4. A sound wave radiated on the front surface of the diaphragm is conducted to the opening part through the acoustic tube 3, but a part of the wave becomes a reflecting wave and tends to return to the diaphragm surface. The reflecting wave is absorbed by the sound abroptive material 4 disposed inside the acousitic tube, and the occurrence of a standing wave inside the acoustic tube is prevented. Since the thickness of the material 4 is thin in the vicinity of the opening part and thick near a speaker unit 1, the impedance variation of the material 4 seen from the reflecting wave is made small, hence the sound absorbing effect is upgraded.
