Title: Valve control device
Inventor: MIYAGAWA KAZUNORI
IPC: F16K31/04
Filed: 1990-12-07
Abstract: PURPOSE:To freely set the rate of opening of a valve correspondingly to a control voltage by driving a motor in response to information about the position of a potentiometer which is operated in association with the valve and the control voltage for controlling the rate of opening of the valve. CONSTITUTION:When a control voltage is supplied to a differential amplifier 22 the output of the differential amplifier 22 is supplied as a driving current to a motor 26 via an absolute value circuit 27. The motor 26 drives a valve 23 and a potentiometer 24 which is operated in association with the valve 23. A voltage caused by information about the position of the potentiometer 24 and applied to the differential amplifier 22 comes close to the control voltage and finally equals the control voltage and then the motor 26 is stopped. Then a predetermined rate of opening of the valve 23 is obtained. A mark judging circuit 28 determines whether the output of the differential amplifier 22 is positive or negative to decide whether the motor 26 is rotated in its normal or reverse direction.

Title: Optical information recording and reproducing device
Inventor: HIROYOSHI JUN
IPC: G11B20/18
Filed: 1990-12-27
Abstract: PURPOSE:To obtain a high-speed device and to improve the reliability thereof by executing demodulation and error correction when a threshold value is set and a first or a second identification signal is detected and executing the verifying action at a recording time by detecting the first identification signal. CONSTITUTION:Data recorded on an optical disk 7 is detected by a photodetector 8. A binarized reproducing signal 12 is converted to parallel from serial by a shift registor 17 and inputted to a data mark detection circuit 18 or a frame mark detection circuit 20 through a change-over switch 31. When the data more than a block number set by a threshold value set circuit 23 is detected, the identification signal 19 or 21 is outputted. Then, the data is processed by a demodulation circuit 27 and an error correction circuit 29 at the timing of detection. On the other hand, when the signal 19 cannot be detected during the verifying action at the recording time, information is recorded again on another sector. When it is detected, the information is recorded again on another sector when an error is detected.

Abstract: The present application is concerned with a solid slow release pharmaceutical dosage unit. More specifically, the invention is directed to a tablet form prepared by direct compression of cross-linked amylose (CLA) having a definite cross-linking degree, (alpha)-amylase and a pharmaceutical agent. The presence of the cross-linked amylose allows a sustained release of the drug, while the (alpha)-amylase permits the modulation of the release time. In other words, the release time of the drug is function of the amount of (alpha)-amylase in the tablet. The amount of (alpha)-amylase is defined in terms of Enzyme Units.
