Title: Impedance reduction preventing device in cut-off mode of dc amplifier
Inventor: NISHIJIMA TAKEO
IPC: G05B9/02
Filed: 1984-08-23
Abstract: PURPOSE:To prevent the effects due to the reduction of an input impedance even through the power supply of a DC amplifier is cut off, by connecting an action contact of a DC relay and an action contact of an AC relay in series to an input circuit of the DC amplifier. CONSTITUTION:When a plug socket 6 is put into a power supply and a power supply switch 5 of a measuring instrument is turned on, an AC relay 9 is immediately turned on. While the power supply is controlled and rectified by a power supply controller 4 and supplied to a DC amplifier 1. This rectified power supply actuates a DC relay 10 with a time delay via a time delay circuit 8 and is turned on. Thus the input side conducts and the amplifier 1 is warmed up satisfactorily to secure a high input impedance. Therefore no disturbance is produced to other gauges. In ase an unexpected accident occurs or a power supply in cut off, the relay 9 first works to separate the input side. As a result, the input side is opened even in case the impedance of the amplifier 1 is reduced due to the cut-off of the power supply. This prevents the generation of disturbance to other gauges.

Title: Optical recording and reproducing device
Inventor: YAMADA KOICHI
IPC: G11B7/09
Filed: 1989-07-07
Abstract: PURPOSE:To always keep a gain of a control system at a prescribed value by holding a signal level of a sum current shifted DC-wise in timing of coincidence of a detection rectified voltage value and a predetermined setting voltage value. CONSTITUTION:The subject device is constituted in such a manner that an output of a detection rectifier circuit 19 is inputted to a comparator circuit 20 for comparing it with the predetermined setting voltage value V0, and when a voltage value obtained by detecting and rectifying a peak value of an output S3 of an AGC 16 is higher than the predetermined setting voltage value V0, a high level is outputted from an output of the comparator circuit 20, and when it is lower than the setting voltage value V0, a low level is outputted. Then, since the output of the comparator circuit 20 is inverted from the high level to the low level state, an output voltage value of a voltage varying circuit 21 upon this coincidence is held by a hold circuit 22 and supplied to a level shift circuit 24 to hold a gain at this time. By this method, no influence is received due to a temp. change, secular change and a disk variation, thus enabling stable control.

Title: Transparent original reader
Inventor: HOSHI AKIMITSU
IPC: H04N1/00
Filed: 1993-06-24
Abstract: PURPOSE:To improve the continuity of a picture and to attain high speed reading by accelerating a stepping motor for a prescribed pulse when a picture reading CCD in a subscanning direction is stopped and started. CONSTITUTION:A CCD 48 is moved in a subscanning direction by a stepping motor 61 and deceleration portion is formed to be movable for the portion of one picture element length of the CCD 48. When the motor is stopped just after an n-th picture element is read in the subscanning direction in the stop operation, the motor 61 is accelerated for the portion of prescribed pulse and stops to read an (n+1)-th picture element. As a result, the sensitivity and shape of the (n+1)th picture element are close to the gravity center position of on ideal picture element at the time of continuous scanning and the vibration amplitude of the CCD 48 after the stop is increased and the ideal moving speed is maintained even after the drive is stopped and the sensitivity and shape of the picture element close to ideal are obtained. At the time of starting, the rising of the subscanning is quickened for the portion of a prescribed pulse to make the speed close to a prescribed subscanning speed. Thus, the continuity of a picture is improved by a simple sequence and the reading speed is quickened.

Title: Digital information reproducing device, and method for reproducing digital information
Inventor: SHIGENOBU MASAHIRO
IPC: G11B20/18
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To surely prevent effect of clock skew during reproduction of digital information which is modulated and recorded at a high density. SOLUTION: A frame synchronous signal detected by a synchronous signal detecting element 6 is output to a skew detecting element 7 and a second one- frame delay element 8. The skew detecting element 7 measures the intervals of the frame synchronous signals to detect, as a first information, the presence of a clock skew, its direction, and its number. Demodulation circuits 10a-10e output generated demodulation error to a skew path detecting element 11 as a second information. The skew path detecting element 11 detects the demodulation circuit 10a-10e without clock skew, using specific algorithm according to the first information and the second information. Then, the skew path detecting element 11 controls a selector 12 which selects output from the demodulation circuit 10a-10e, based on the detected result.

IPC: H01S5/042
Filed: 1980-12-12
Abstract: PURPOSE:To prevent semiconductor LASER from degrading or destruction, by supplying constant current into LASER, detecting optical output, and controlling temperatures so as to make constant output. CONSTITUTION:When output of a semiconductor LASER element 1 decreases, a drive circuit 11 will drive a thermal control element 10 to further decrease LASER 1 temperatures. The LASER 1 is supplied with constant current regardless of LASER temperatures by a constant current circuit 8. And so, when LASER temperatures go lower, output will go higher and controlled constantly. The control element with a use of Peltier element makes output control of the LASER temperature difference between 60 and 70 deg.C. This constitution is slow in responce speed but enables effective output control of semiconductor LASER having a factor to cause gradual output changes.

Abstract: PURPOSE:To prevent biting shock and large variation in tension and to preform smooth biting rolling even in a one roll driving system by setting an opening between a pair of rolls immediately before biting the stock. CONSTITUTION:A rolled stock 1 is rolled between a couple of two rolls of a driven roll 15 and a non-driven roll 18.

At biting the stock 1, a speed of the roll 18 is decreased to about a prescribed speed, so that smooth biting for the stock 1 is performable.
