Title: Frequency divider
Inventor: OGI ZENICHIRO
IPC: H03K23/64
Filed: 1991-05-22
Abstract: PURPOSE:To realize the frequency divider able to reduce the test time by providing the mode to output an input clock as it is so as to avoid frequency division. CONSTITUTION:The frequency divider consists of basic blocks connected in cascade. Each block is formed in such a way that a clock input 3 and an output 4 of a T flip-flop 1 are inputted to a multiplexer 2 and a control signal 5 is used to switch the clock input 3 or the output 4 of the T flip-flop 4 and the output is outputted to an output 6. In the frequency divider in which the basic blocks are connected in cascade, a frequency division ratio is optionally set by setting a control signal input of each stage, and when all the stages are set to the mode not frequency-dividing the input signal at test, the clock is directly fed to the logic circuit clock of the frequency divider and the test is conducted in a short time without frequency division time.

Title: Damping device for body of revolution
Inventor: YOSHITOME SEIYUKI
IPC: G11B19/22
Filed: 1978-09-25
Abstract: PURPOSE:To make it possible to damp smoothly and rapidly a turntable by firstly damping it by an electromagnetic damping device and then by changing it for an auxiliary mechanical damping device, for example, when its rotational frequency decreases down to a certain value. CONSTITUTION:At the time of damping, power supply to motor drive circuit 26 is stopped by change-over switch 29 and electromagnetic damping circuit 30 operates to damp motor 27 electromagnetically. As a result, the rotational frequency of a turntable decreases and a state where it reaches a fixed value is detected by integrating circuit 31, 1st and 2nd voltage comparator circuits 32 and 33, inverter circuit 30, and AND circuit 35 to drive auxiliary damping device 36, thereby reducing the rotational frequency of turntable 22. In a state where the rotational frequency further decreases below the fixed value, the damping of auxiliary damping device 36 is reset. Therefore, constant damping force can be obtained until turntable 22 stops, so that the rapid and smooth damping of turntable 22 can be attained.

Title: Method and device for detecting touching signal
Inventor: ISA MASAJI
IPC: G01B7/00
Filed: 1981-07-28
Abstract: PURPOSE:To eliminate the time delay in detection and the effect of overrun of the detecting device, by obtaining the time or displacement at the instance of contact from the time or displacement at the instance of the contact when the displacement signal of a contact probe has reached two or more preset levels. CONSTITUTION:When the displacement detector 10 having a contact probe 12 is moved in the direction of an arrow and the contac probe contacts a body 8, the probe 12 is relatively displaced with respect to a holding part, and outputs a signal V in response to the displacement X. The value of the signal V is V0 when the probe does not contact the body 8. The preset values V1 and V2 are established in advance. The output X1 and X2 in response to the displacement of the displacement detector or the times t1 and t2, when the signal V reaches the levels V1 and V2, are memorized. From this data, the time t0 or the relative displacement X0 at the instance of the contact is obtained. In this constitution, the time delay from the instance of actual contact to the generation of the contact signal or the effect of the overrun of the detector can be eliminated.

Title: Photo coupler
Inventor: YASHIRO YUJI
IPC: H01L31/12
Filed: 1990-05-07
Abstract: PURPOSE:To supply a trigger current of constant value to an input circuit independently of the power supply voltage, by connecting a constant current element in series with a light emitting diode, which constant current element supplys a driving current of constant value independently of the voltage value of a power supply which applies a driving voltage to the input circuit. CONSTITUTION:When a control signal (e) is delivered to an input circuit 7, a conduction state is obtained and the driving voltage of a power supply 12 is supplied to an input circuit 7. A constant current flows in a light emitting element 2 through a constant current element 22, and the light emitting element 3 generates light. Said light is received by a photo detector 3, and a signal is outputted from an output circuit 8. Hence a photo coupler wherein the limitation caused by the input power supply voltage value is very little and general- purpose properties are high can be realized, by applying the input circuit 7 having constant current characteristics to a photo coupler. By replacing said circuit with a constant current element, a highly reliable device can be obtained, and structural miniaturization is enabled.

IPC: G01R13/20
Filed: 1982-07-09
Abstract: PURPOSE:To simplify circuit constitution and to perform a quantitative measurement up to a frequency which is measurable by a synchroscope, by observing a waveform by the synchroscope. CONSTITUTION:The fluorescent screen of the synchroscope 1 is observed through an image sensor 2 and a measured waveform is amplified by a brightness measuring part 3 and converted into a binary signal by a binary-coding part 4 on the basis of a specific threshold level. A peak value measuring part 5 counts the horizontal synchronizing signal of the sensor 2 and stops the counting by the binary-coded signal. Consequently, the number of scan and read pulses up to a brightness detection position is measured from the vertical synchronizing signal. A specific level of the observed waveform is determined and extracted by an extracting part 6 with the synchronizing signals of the sensor 2 according to a scanning line and a signal is sent to a time measuring part 7. The measuring part 7 measures the width of the binary-coded signal of the extracted part. Thus, respective measured values are displayed on a display part 8 to find the waveform peak value and width of the synchroscope.
