Patent JP-S61269488-A (JP)
Title: Subscriber circuit
Inventor: YOSHIDA TOSHIHISA
IPC: H04M19/00
Filed: 1985-05-22
Abstract: PURPOSE:To obtain a large detection level for origination, resetting, a dial pulse signal, etc., by using two resistances whose resistance values are nearly equal to each other between the output of the 1st entire-area passing circuit having a switched capacitor and the output of the 2nd entire-area passing circuit of nearly the same constitution with the 1st circuit, and outputting dial pulses, etc., from the connection point of the two resistances. CONSTITUTION:The base potential of a transistor (TR) 1 is set by a resistance 4 and a Zener diode 2 at a subscriber current circuit part and the collector current of the TR 1 is determined by the resistance 3 to supply a constant speech current to a subscriber. A speech signal from the subscriber side is applied between communication line connection terminals 41 and 41 in opposite phase relation with earth points 26 and 35, so no output appears at a subscriber signal output terminal 44 where a subscriber signal averaged by resistances 38 and 39 appears. Therefore, the speech signal from the subscriber is led out to a speech signal output terminal 43. An operational amplifier 36 which is connected between grounding in terms of DC and grounding to the chassis, on the other hand, is applied with the variation of the speech line connection terminal 42 to the ground, so the variation in DC voltage due to the connection and disconnection of a subscriber side loop is detected at the subscriber signal output terminal 44.

Abstract: PROBLEM TO BE SOLVED: To provide an interpolation circuit wherein the capacity of a look-up table memory can be reduced by interpolating such phase angle data as decided by a high order bit of an A/D converted digital data with a low-order bit. SOLUTION: An encoder output is sampled with A/D converters 11a and 11b and converted into A and B phase digital data DA and DB of N bits.

IPC: H01L27/04
Filed: 1982-06-28
Abstract: PURPOSE:To break a dummy wiring section easy to be broken prior to true wiring prior to a true wiring section even when a primary factor of breaking such as a surge is generated, to prevent the breaking of the true wiring section and to improve reliability by setting up dummy wiring apart from true wiring. CONSTITUTION:Dummy Al wirings 13, 14 are each connected to Al wirings 11, 12. A distance d2 between the Al wirings 13, 14 is made shorter than one d1 between the Al wirings 11, 12.

Title: Key matrix circuit
Inventor: ANDOU MASAYUKI
IPC: H04M3/60
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate the reduction of the noise margin for the lock key detection level by connecting a lock key to a key matrix circuit via a three-state buffer. CONSTITUTION:Enable terminals EN1-3 of three-state buffer gates G1-3 are connected a row R1 in a key matrix circuit which can store a lock key. Thus a current flows to the R1 from a plus voltage source VH via a resistance P4 when the R1 is designated and a lock key SR1 is closed. Thus the voltages of terminals EN1-3 are set at VR1, and gates G1-3 are all opened. Therefore the voltage VD0 of a data line D0 is equal to the output voltage of logic ''0'' level of the gate G1. This never reduces the detection noise margins of lock keys SR1-3, and these keys can be stored into the key matrix circuit.

IPC: H04N1/417
Filed: 1981-07-16
Abstract: PURPOSE:To efficiently perform encoding by using a estimating order encoding system, by encoding picture signals having numerous level numbers after they are once converted into signals having fewer level numbers. CONSTITUTION:A signal of N1 value which roughly designates a picture signal of N value is first obtained from the picture signal of N value by a N-notation coded circuit 8.

Title: Feedback amplifier
Inventor: FUKUSHIMA ISAO
IPC: H03F1/34
Filed: 1980-08-15
Abstract: PURPOSE:To increase both the gain of a feedback amplifier and the setting accuracy of the filter cutoff frequency, by dividing with high accuracy the output signal of an operational amplifier with the ratio of resistance and then giving the feedback to the divided output signals. CONSTITUTION:An operational amplifier 1 is installed between an input side terminal 5 and an output side terminal 6 that constitute a feedback amplifier. Then the input signal supplied from the terminal 5 is applied to the negative input terminal of the amplifier 1 via a resistance 2, and the positive input terminal of the amplifier 1 is earthed. Then a capacitor 4 is connected between the negative input terminal and output terminal of the amplifier 1, and at the same time a series circuit of resistances 13 and 14 is connected. A resistance 15 is put between the intersection of the resistances 3 and 14 and a positive input terminal. In such constitution, the output of the amplifier 1 receives an alternating division of voltage through resistances 14 and 15, and then the feedback is carried out via the resistance. Thus a feedback amplifier is obtained. As a result, both the gain of a feedback amplifier and the control accuracy of the cutoff frequency of a filter can be greatly increased.

Title: Analysis method of contaminated particle in compressed gas
Inventor: FUA CHI WAN
IPC: G01N15/06
Filed: 1995-05-10
Abstract: PURPOSE: To detect the grains in the cylinder gas over a wide range by taking a balance of the pressure of the lead-in gas, and maintaining the gas at a desirable set temperature. (pressure difference gauge, molecule cluster, saturated steam pressure). CONSTITUTION: Two flow passages passing from a valve 12 through a valve 1 and a valve 2 are purged with the nitrogen purge gas 11. The valve 1 is closed before sampling the high-pressure raw material gas 10, and since the gas 10 is passed through a filter 3, a sensor 8 does not detect a sudden rise of the pressure by the gas 10, and separated from the polluted material. During this time, an orifice 7 returns the gas 10 to the sensor 8 for charge till the pressure before and after the valve 1 become equal to each other. After the pressure become equal to each other, the valve 1 (2) is opened (closed), and sampling is started. Flow of the gas 10 is passed through the sensor 8 and a temperature zone 9 at the same pressure on the basis of the control of the orifice 7 so as to maintain the temperature of the gas 10 at the desirable set temperature.  Flow of the gas 10 passing through the sensor 8 can be decided by an indication of a flowmeter 16, and indicated flow during the sampling period is integrated so as to obtain the all sample volume, and grain concentration in the cylinder gas over a wide range can be detected.

Title: Exposure controller in electrophotographic copiers
Inventor: KAWAI YOSHIHISA
IPC: G03G21/00
Filed: 1977-09-16
Abstract: PURPOSE:To make possible the magnification or reduction of exposure adjustment range and enable copying images of good quality to obtained by correlatively controlling the previous exposure and image exposure. CONSTITUTION:If a variable resistor 9 is set at ''BRIGHT'' position, then the quantity of light of an image exposure lamp 8 increases as shown by the straight line (e), the quantity of light of a previous exposure lamp 7 decreases shown by the straight line (d), and photoreceptor sensitivity increases as shown by the curve (f). Hence, the surface potential attenuation quantity (g) of the photoreceptor 1 increases as the synergistic effect of the increases in the quantity of light (e) of the exposure lamp 8 and the sensitivity (f). If the variable resistor 9 is set at ''DARK'' position, the above becomes exactly opposite. Hence, the exposure adjustment range increases. When the inverter 12 connected to the lighting circuit 13 of the previous exposure lamp 7 is shorted by changing over a switch SW from the contact (a) to (b), then the sensitivity of the photoreceptor makes the action opposite from the change in the image exposure lamp 8 and therefore the adjustment range by the variable resistor 9 is decreased.

IPC: G01S5/14
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of discrimination and measurement of a position of a user terminal. SOLUTION: Each satellite in a satellite communication system provides the array of overlapped spot beams 30A-30G on a surface of the earth. The position of each of the spot beams 30A-30G is known at any moment. A terminal on the earth receives all receptible spot beams and discriminates a spot beam that provides a signal whose level is over a predetermined level. Which of areas 58A-58M the terminal occupies is quickly discriminated by mapping which spot beam is more than a limited level and receptible. Thus, the position of the terminal on the earth is quickly discriminated.
