Filed: 1991-07-19
Abstract: PURPOSE:To obtain a magnetic recording medium having high output and excellent S-N ratio by incorporating urethane resin having a yield point and magnetic metal powder into a magnetic layer and limiting the average surface roughness of the magnetic layer. CONSTITUTION:Urethane resin having a yield point and magnetic metal powder are incorporated into a magnetic layer 2 on a substrate 1 and the average surface roughness of the magnetic layer 2 is regulated to <=0.02mum.

Title: Encoder and decoder
Inventor: SUMINO SHINYA
IPC: H04N19/60
Filed: 1989-08-05
Abstract: PURPOSE:To eliminate the correlation of multi-dimensional components efficiently and to improve the compression efficiency by detecting a minimum value and a maximum value of an input signal subject to block processing, subtracting the minimum value from the input signal, normalizing the result by a difference between the maximum value and the minimum value, that is, the dynamic range, and applying the vector quantization to the result. CONSTITUTION:A minimum value 5 and a maximum value 7 are detected from an input signal 1 subject to block processing by a minimum value device 4 and a maximum value device 8 respectively. Moreover, a difference signal 11 between the maximum value 7 and the minimum value 5 is calculated. The input signal 1 is delayed by a time for detecting the maximum value 7 and the minimum value 5 at a delay device 2 and a subtractor 8 subtracts the minimum value 5 from the input signal. Furthermore, the difference signal 9 is divided by a difference signal 11 at a normalizing device 12. As a result, the level of a normalized signal 13 is between '0' and 'b', and the result is subject to vector quantization by a vector quantizer 14. A coder 16 encodes a quantized value 15, the minimum value 5 and the difference signal 11 and they are sent. Thus, a considerably large compression effect is obtained with a few vector numbers.

Title: Driving equipment of solenoid
Inventor: IMAMURA TOMOATSU
IPC: B41J9/44
Filed: 1984-09-28
Abstract: PURPOSE:To realize the small sized solenoid and reduced power supply by shortening the conduction period of the driving current by controlling the solenoid current according to its variation. CONSTITUTION:The solenoid current Is is detected as the voltage drop by a resistor Rs used for current detection means. Based upon the current Is, a discrimination circuit 49 examines the dynamic state of the load being driven. That is, the differentiation circuit 50 differentiates the current Is and delivers the results to the positive terminal of the comparator COM1. A reference voltage Va is divided by resistors R4 and R5 and provides a voltage Vc for comparison. When the differentiation value SI is higher or lower than Vc, the comparator 51 outputs Schmitt pulse of H level or L level to the control unit 52, respectively. When the driving signal DV changes from H to L, the control unit 52 inverts the driving signal DVH from H to L, which shortens the conduction period of the driving current.

Abstract: PROBLEM TO BE SOLVED: To control gas such as air with a high speed response and high precision by adjusting the opening of a piezo valve based on a result obtained by comparing a real flow rate obtained by a differential pressure flow meter with a setting flow rate. SOLUTION: A piezo valve 33 provided with high speed responsiveness and a venturi flow meter 10 having high flow rate measurement precision are connected in series. A real flow rate obtained by the venturi flow meter 10 is compared with a setting flow rate and the opening of the piezo valve 33 is adjusted based on the result.

Abstract: PURPOSE:To know the time of service interruption and at the same time to ensure a quick reset to the normal time, by stopping the working of a clock counter to hold the service interruption time data when the service is interrupted and counting the number of clocks equivalent to the period of service interruption by means of a different high-speed clock counter.

Then the contents (the number of clocks equivalent to the period of service interruption) of the counter CTR2 are read and applied to the counter CRT1. Thus the time can be reset to the present normal time.
