Title: Fet source coupling logic circuit
Inventor: OOTSUKA TOMOYUKI
IPC: H03K17/687
Filed: 1984-01-31
Abstract: PURPOSE:To realize an FET source coupling logic circuit with less DC level fluctuation attended with changes in mark rate in an output signal by attaining the reduction of voltage to a drain supply voltage to a differential switch part by means of a Schottky barrier diode or a junction diode and setting the FET of a source follower to a degree where its gm is not decreased extremely. CONSTITUTION:Since any of FETQ1 or Q2 is turned on, a current flowing to the differential switch part is a constant current VD at steady-state because of the function of an FETQ5 and a foward voltage drop of diodes Di1-im constituted by Schottky diodes is constant. A voltage drop of ID.RS is produced by a Q3 or Q4 with a forward resistances RD of the Q3 and Q4, and its output voltage value V is VDD-(mVbi+IDRS) when the Q1 or Q2 is turned off. Thus, the current flowing to the Q6/Q7 is constant and a defect that the pulse width is changed because of the fluctuation of the DC level having been generated in a conventional system attended with the mark rate of the output signal.

IPC: H04N19/00
Filed: 1990-01-24
Abstract: PURPOSE:To attain correct separation and reproduction of a vertical Synchronizing signal from a composite synchronizing signal by feeding back the separated vertical synchronizing signal so as to switch the separation timing depending on a synchronizing period of the vertical synchronizing signal and a video period. CONSTITUTION:A polarity switching device 3 inverts an inputted composite synchronizing signal S1 when the signal is in a synchronizing period t2 of a separated vertical synchronizing signal S2 and outputs a pulse S3 to a one-shot pulse generator 1 as it is when the signal is in a video period. The one-shot pulse generator 1 uses a leading of the pulse S3 from the polarity switching device 3 as a trigger and generates a pulse S4 with a prescribed pulse width longer than a synchronizing period t1 of a horizontal synchronizing signal and shorter than a half one cycle t2 of the horizontal synchronizing signal. A synchronizing separator circuit 2 samples the composite synchronizing signal S1 at the trailing edge of the received pulse S4 and outputs separately the vertical synchronizing signal S2.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To notify the state of an electronic equipment to the outside without providing any special interface on the outer surface of a state analysis device nor with a special operation by converting plural information showing the state of the electronic equipment into a modulation signal with high frequency to radiate it as the modulation light via a power supply display LED and receiving the modulation light to externally know the state of the electronic equipment. SOLUTION: When the power supply of an electronic equipment 1 is applied, an equipment state information production means 2 collects the information on the states of prescribed parts of the equipment 1 and generates the information to be notified to the outside. A modulation means 3 modulates the high frequency by the notification information and emits the high frequency modulation light from a power supply display LED 5 via an LED drive means 4. A photodetection analysis means 6 placed outside the equipment 1 analyzes the modulation light received from the LED 5 and detects the internal state of the equipment 1. The LED 5 originally functions to show that the power supply is turned on and accordingly no special state notification means is required.

Abstract: PURPOSE:To provide a mechanical seal which can seal up a poor-lubricating fluid with a little liquid during a long period of time by supplying liquid to a seal ring formed of liquid-containing material from one end of a hole not opened in the seal end surface. CONSTITUTION:A hole 15 is mounted on a seal ring 6. The hole 15 reaches a liquid-containing portion communicating with a surface 13 forming a seal end surface S.

Accordingly, even if seal fluid L is bad in lubrication, or it is gas, the seal end surface S maintains satisfactory shaft sealing during a long period of time. The liquid is supplied to the interior of the seal end surface S through the hole 15 by liquid-containing property, that is, permeability of a material so as to reduce the consumption of liquid.

Title: Speed calculation system for vehicle
Inventor: WATANABE ASAKI
IPC: G01P3/50
Filed: 1988-01-28
Abstract: PURPOSE:To achieve a higher accuracy, by measuring a pulse shift time upto the subsequent rotational speed pulse input each time a reference time interval pulse is generated while a rotational speed pulse input from the preceding measurement of a pulse shift time is measured. CONSTITUTION:Time is measured with a counter 7 from the time when a refer ence time interval pulse is generated to the subsequent rotational speed pulse input to be represented by DELTAT1. Time is measured from the time when the subsequent reference time interval pulse is generated to the first rotational speed pulse input to be represented by DELTAT2. Then, the number of rotational speed pulses during the period is counted (n) with a counter 1. When a reference time is represented by T, time Tp to a time measuring point is expressed by the formula TP=T-DELTAT1+DELTAT2. As (n) pulses are inputted during the period, the average pulse width is given by Tp/n and the speed V is expressed by the formula V=3.6piD.n/Tp.P. This enables accurate calculation from a low to high speed.

Abstract: PURPOSE:To discriminate the expiration of the service life of a magnetic recording medium in accordance with a reproduced signal level by discriminating the expiration of the service life in a position where a reproduced signal is recorded on the magnetic recording medium when it is detected that the level of the reproduced signal is lower than a prescribed value. CONSTITUTION:A signal level comparator 14 compares the reproduced video signal level with a reference level signal supplied from a reference signal generator 15.

Title: Serial printer
Inventor: KONISHI FUSAICHI
IPC: B41J29/42
Filed: 1984-02-01
Abstract: PURPOSE:To print constantly at a predetermined position of a printing paper and enable to enhance printing quality, by starting a printing operation at a position at a predetermined distance from an edge of a printing paper, irrespectively of the present or absence of stagger in the fitting position of a sheet form paper. CONSTITUTION:When starting a printing operation by fitting a printing paper 12 to a platen 11, a carriage 9 is first returned to a left-hand return position, immediately followed by moving the carriage 9 rightward. In this case, an optical sensor 9 detects the left edge 12a of the paper 12, and a printer starts the printing operation at a position reached by the carriage 4 by moving rightward by a predetermined distance from the detected position. Since the stagger in fitting the paper 12 generally occurs as a parallel leftward or rightward stagger, it is sufficient to set the printing-starting position for the first printing line. However, in the case where the paper is skewly fitted, the printing-starting position is set for each line as required.
