Title: Arithmetic unit
Inventor: MARUYAMA RYOJI
IPC: G01R21/133
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To provide highly accurate arithmetic unit, which computes electric energy, electric power, amount of reactive power and reactive power at a low cost. SOLUTION: A first and a second one-bit A/D converters 101 and 102 convert respective input voltages, which are directly proportional to the voltage and the current of a system to be measured respectively, to one-bit codes respectively. In a first and a second up-down counters 109 and 110, the up/down counts of the respective clocks are controlled by the codes, and the A/D converted value of each input voltage is outputted respectively. A latch 113 holds and outputs the data of the inputted data one clock before. An adder-subtractor 112 increments and decrements the respective output data of the first and second up-down counters 109 and 110 by 1 a numerical value 1 to and from the output data of the latch 113 under the control by the respective output data of the first and second one-bit A/D converters 101 and 102 and the exclusive OR of the respective output data. Thus, the calculation data proportional to the product of the respective input voltages are outputted to the latch 113. An adder 114 computes the data outputted from the latch.

Title: Token circulation time fixing system
Inventor: OKAJIMA EIJI
IPC: H04L12/40
Filed: 1994-03-10
Abstract: PURPOSE:To maintain token circulation time fixed by surely transmitting a data frame every time a token is received. CONSTITUTION:A CPU 14 sets the data of a fixed length to be transmitted when new data to be transmitted are not present at the time of receiving the token next time in a transmission buffer memory 11 and issues a transmission request command for requesting the transmission of the data inside the transmission buffer memory 11 at the time of the receiving the token to a transmission LSI 12 beforehand. When the new data are present, the data are set. At the time of receiving the token, the transmission LSI 12 transmits the data inside the transmission buffer memory 11 and issues a transmission completion report. The CPU 14 immediately issues the transmission request command again to the transmission LSI 12 and sets the data of the fixed length to the transmission buffer memory 11.

Title: Clamp circuit
Inventor: TAJIMA OSAMU
IPC: H04N5/18
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To incorporate a clamping capacitor to an IC by decreasing a charging/discharging current generated by a charging/discharging control circuit to a multiple to a reciprocal to a current amplification factor of a transistor(TR) so as to decrease the capacitance of the capacitor. SOLUTION: A charging/discharging control circuit 4 substracts a clamp level stored in a clamping capacitor 3 from a video signal received by an input terminal tin 1 and generates a charging/discharging current to the clamp capacitor 3 on the basis of the result. TRs Q11, Q12 configure a current mirror circuit and draws a current corresponding to a collector current of a TR Q6 from an emitter of a TR Q13. Since a base of the TR Q13 is connected to the current mirror circuit consisting of TRs Q14, Q15, a TR Q15 supplies the current equivalent to the base current of the TR Q13 from its collector to the clamp capacitor 3 as a charging current I charge. Thus, the charging/discharging current is decreased by a multiple of a reciprocal of the current amplification factor of TRs Q13, Q18.

Title: Driving method of matrix display panel
Inventor: FUJITA YUJI
IPC: G09G3/30
Filed: 1990-02-20
Abstract: PURPOSE:To reduce the maximum power consumption and to reduce the circuit component cost by controlling a DC-DC converter power source so that a modulating voltage becomes a constant voltage in a state below a power limiter value and constant electric power in a heavy load state. CONSTITUTION:The modulating voltage Vm supplied to a data driver 11 is supplied by a DC-DC driver 17 equipped with an electric power limiter circuit, and made into the constant voltage at the electric power limiter value and the constant electric power in the heavy load state. Therefore, even if a light emission pattern wherein the power consumption becomes large is employed, the power consumption is lower than the maximum power consumption and becomes constant. Consequently, the maximum power consumption is reduced and the circuit components are also reduced in cost.

Title: Magnetic seal device
Inventor: MARUYAMA TERUO
IPC: F16C33/74
Filed: 1979-04-04
Abstract: PURPOSE:To maintain the sealing of a lubricant fluid for a long time without impairing the load characteristics of a device by the method wherein a magnetic fluid of low viscosity is used as lubricant oil for the fluid bearing and a fluid of high viscosity is used as magnetic seal in a high-precision rotary device, such as a VTR cylinder. CONSTITUTION:By the ''barrier'' formed by sealing magnetic fluid 8 of low volatility, magnetic fluid 5 of high volatility is shut off from the atmosphere outside the device, and the voltatilization of magnetic fluid 5 can be confined to the small volume of gap 13. As a result, a fixed amount of lubricant magnetic fluid 5 can be kept at the oil film part of the fluid bearing at all times even after a long time of disuse. Further, the space between lubricant magnetic fluid 5 and sealing magnetic fluid 8 is sealed by two magnets 6, 9. Moreover, since air gap 13 is provided between them, contact between magnetic fluids 5, 8 is prevented. By this, it is possible to maintain stable rotational characteristics for a long time even under the bad circumstance of low torque.

Filed: 1991-02-13
Abstract: PURPOSE: To attain the high speed of a writing(storing) operation by providing a buffer means which receives and stores information from a processing means, and a data cache means which receives and stores the information. CONSTITUTION: When a central processing unit(CPU) 100 executes a storage instruction, access to a data cache 112 is performed for checking a hit. When a cache hit occurs, storage data 110 and 124 and addresses 118 and 120 are written in a storage buffer 128, and the data cache 112 is not updated. The check of the cache and the update of the buffer occur in the same time necessary for a load, and performance can be improved without necessitating any extra time. The buffer 128 has the finite number, and when the buffer 128 is full and the storage is executed, the CPU 100 stops in order to make one or more entries empty. When a cache error occurs, the CPU 100 stops and processes the error.
