Title: Zero detecting circuit
Inventor: WATANABE TAKESHI
IPC: G06F7/74
Filed: 1984-03-28
Abstract: PURPOSE:To detect zero at a high speed by a small number of gate stages, by generating a signal for signifying all zero and a signal for showing the number of digits of zero continued from the head, an N byte unit. CONSTITUTION:A zero detecting signal Z11-N of a zero detecting part goes to ''1''; in case the first digit of the first byte is ''0'' and the second digit is not ''0'', and Z12-N goes to ''1''; in case both the first and the second digits of the first byte are ''0'', and the first digit of the second byte is not ''0''. Thereafter, each of the second - the fourth half words has the same meaning. It is inputted to an encoder, and the number of digits of the upper continuous ''0'' is displayed. In such a way, the number of digits of zero of a data having the high-order continuous zero is binary-coded and outputted, and the number of gate stages of the encoder can be simplified to two stages from three stages.

Title: Copying machine
Inventor: MURAI TATSUYA
IPC: G03G15/043
Filed: 1988-03-14
Abstract: PURPOSE:To improve the efficiency of copying by controlling the position of a lighting means according to the temperature of a contact glass. CONSTITUTION:An entire copying machine is controlled by a central processing unit (muCPU) 100. The temperature detected by a contact glass temperature detecting sensor (thermistor) 36 is converted into an electrical signal by an A/D converter 101 and transmitted from an I/O interface 102 to a unit 100. Since the unit 100 switches a scanner position according to the detection of temperature, it controls scanner stopping positions (A and B positions) where a scanner motor 103 and the sensors for stopping the scanner (photosensor) 104 and 105 are provided. Thus, the abnormal rising of temperature in the contact glass can be prevented, so that a cooling fan, etc., can be miniaturized and the efficiency of copying can be improved.

Title: Electronic cash register
Inventor: SHIYUDOU HARUKI
IPC: G07G1/12
Filed: 1983-03-31
Abstract: PURPOSE:To obtain an electronic cash register which can perform the discount register with a simple operation and has a small and inexpensive keyboard, by operating the price after discount for an article to be registered and then registering the result of price operation. CONSTITUTION:When an operator pushes a discount key, a CPU checks a register flag 33 and then checks the set/reset of a discount permission flag 36. The flag 36 is set if the discount sale is permitted for the corresponding article. Thus a table 31 is searched based on the address of the data corresponding to an article key D1 stored in a save area 37. A discount factor corresponding to the number of a discount table 38 is read out to the key D1, and a discount amount is calculated. Then the discount amount is subtracted from the total amount corresponding to the key D1. In such a way, a discount operation is performed to the corresponding article just by pushing the discount key in case the discount registration is desired. Then a price obtained after discount is automatically registered to a discount register area 32.

Title: Integrated circuit and test mode setting method therefor
Inventor: OISHI KAZUYUKI
IPC: G01R31/3185
Filed: 1994-03-29
Abstract: PURPOSE:To provide a proper test mode setting method for integrated circuit. CONSTITUTION:Data 19 in a data bus is fed to a control data decoder 5 via the first register 3. The decoder 5 operates to decode and feed the internal control data 21 of the data 19 to a random logic circuit 15. Also, the decoder 5 extracts test mode data 23 and a test flag 25 from the data 19 for transmission to an AND circuit 7. This circuit 7 feeds a value of 0 to the second register 9, when the test flag 25 is 0, while sending test mode data 23 thereto when the flag 25 is 1. The next stage test mode decoder 11 of the second register 9 judges that no test mode exists when output from the circuit 7 is 0, and sends relevant information to a test circuit 13. Furthermore, when output from the circuit 7 corresponds to the test mode data 23, the decoder 11 decodes the data 23 and determines test mode. The test circuit 13 causes a logic circuit 15 to implement a test according to a test execution signal 27 and the test mode from the decoder 11.

IPC: G03G15/04
Filed: 1986-03-19
Abstract: PURPOSE:To reduce the torque hunting by performing the operation of drive command signals neglecting the rotational speed of a motor in case the rotational direction changes within a predetermined time. CONSTITUTION:A motor rotational direction detector 31 detects the rotational direction of a motor 21 by two (2) pulses P1 and P2 of different phases supplied from pulse generators 33 and 35. The pulse P2 outputted from a pulse generator 35 is supplied to a counter 37 as well and counted. A CPU 27 works out the command signal of a motor impressed voltage V* and a sliding frequency fs* from the accelerator pressing amount A and the number of revolutions N and supplies the command signal to a PWM oscillator 39. In case the motor rotational direction signal Q is uneven, the feedback of the number of revolutions of a motor N is stopped. That is to say, even if N=0, the motor drive command signal V* and the sliding frequency fs* is worked out.

Title: Hydraulic buffer
Inventor: ENDOU NOBUYUKI
IPC: F16F9/44
Filed: 1981-04-20
Abstract: PURPOSE:To prevent a damping property from fluctuating due to the change in the temperature of oil, by connecting the electromagnetic coil of a solenoid unit to a resistor whose resistance changes in response to the temperature of oil to control the opening pressure for a damping valve according to the attractive force of the solenoid unit. CONSTITUTION:When a solenoid unit 18 is excited, an expansion-side damping valve 20 for closing a valve seat 22 is pulled on the attracting end 24 of a piston 2 to increase the thrust on the valve seat to change the damping force. A negative resistance element 50 is mounted in the vicinity of the solenoid unit 18 so that the element faces a valve hole 21. The negative resistance element 50 is connected in series with the coil 17 of the solenoid unit 18. Even if the viscosity of working oil drops due to the rise in its temperature, the damping force is prevented from falling but is kept constant because the resistance of the element 50 decreases to augment the electrical current of the coil 17 to heighten the opening pressure for the valve 20.

Subsequently, a flow rate measuring orifice 22 and a flow rate adjusting valve 23 are connected, and also a suction pipe 24 is connected. The pipe 24 is connected to the duct 8. Since sample gas is led in by utilizing a pressure difference by the draft machine 9, a special leading-in pump and its protective equipment become unnecessary, and the equipment is simplified.

Even if the residual quantity is small, the sensor signal of higher voltage than the conventional is supplied to the AD conversion part 71. Consequently, residual quantity measuring precision can be enhanced as compared with the conventional.
