Title: System for judging damage of paper
Inventor: TAKAHASHI HISASHI
IPC: G07D7/182
Filed: 1982-09-27
Abstract: PURPOSE:To enable positive judgement without receiving the influence of a pattern, by a method wherein the pattern of papers is subjected to photoelectric conversion and the converted pattern is sampled to be converted to a digital value which is, in turn, temporarily stored as an input pattern to be compared to a reference pattern at every sampling. CONSTITUTION:The pattern of papers is converted to a digital value at every the sampling pulse of a control circuit 3 by an A/D converter 2 to be stored in a memory part 4 as an input pattern. An operation circuit 7 calculates the average value of the input pattern to calculate the difference with a reference pattern and each input pattern is compensated by using said difference. The compensation sampling pulse is repeated several times. Finally, the count value remaining in a counter 8 is compared with the value stored in a memory part 6 and, only when the counter value is larger, the presence of contamination is judged. As the result, even with respect to papers having any printing pattern, the judgement of contamination can be accurately performed.

Title: Semiconductor memory circuit
Inventor: TOYODA KAZUHIRO
IPC: G11C11/414
Filed: 1982-09-27
Abstract: PURPOSE:To shorten the access time to make the operation high-speed, by using a transistor TR provided with the amplifying function instead of a diode for level shift. CONSTITUTION:Pairs of bit lines BL1-BLn are provided with plural memory cells MC respectively. Pairs of bit line switching TRs Q11-Qn1 are connected in series to pairs of bit lines BL1-BLn to constitute what is called current switches. Therefore, only one selected pair of bit lines are made active. TRs Q2 and Q3 constitute what is called a Darlington circuit, and a base current (the base current of the TRQ2) required for generating the same current as a current supplied conventionally to output points B (B1-Bn) is reduced considerably to 1/beta by the amplifying function of the TRQ3 (amplification rate beta). As the result, the voltage drop due to this base current is reduced to about 1/beta in a resistance R, and the level difference between output points B is increased to shorten the access time.

Filed: 1980-11-26
Abstract: PURPOSE:To elevate the discrimination accuracy with the determination of a phase difference between the object current and voltage by measuring times with the same insulation value existing and non utilizing two comparators through separate half-wave rectification of the current and voltage in a protective relay in the power system. CONSTITUTION:Current I and voltage E to be discriminated undergo a half- rectification. By so doing, a voltage K1¦I¦across a resistance R13 is applied to the first input of a comparator 1-1 and a voltage K1¦I¦-K2¦E¦equivalent a difference in the voltages across a resistances R14 and R20 to the second input thereof. In addition, a voltage K2¦E¦-K1¦I¦equivalent to a difference in the voltage across resistances R17 and R21 is applied to the first input of comparator 1-3 and a voltage K2¦E¦across a resistance R22 is applied to the second input thereof. The comparators 1-1 and 1-3 compare the inputs to measure the times with the same absolute value existing and not existing respectively thereby discriminating a phase difference between the current and voltage. This cancels- out the factor of increasing errors contained in the K1¦I¦and the K2¦I¦thereby elevating the discrimination accuracy.

Filed: 1988-07-05
Abstract: PURPOSE:To recover useful components from by-produced chlorides of a process for producing titanium tetrachloride from Ti-contg. ore, etc., and to reduce discarding cost as well by performing washing repeatedly with the same washing water successively from later stages to earlierstages of recovery. CONSTITUTION:Plural times of washing are performed repeatedly with a same washing water successively from post stages to forestages of recovery of by- produced chlorides produced in a process for producing Ti tetrachloride from Ti-contg. ore or synthetic rutile by chlorination. In this process, a fresh washing liquid is used in the first stage for the final washing of the by-produced chlorides, then washing liquid discharged from the final washing stage is used for the washing of the product of a preceding stage, then washing liquid discharged from the succeeding washing stage is used for the washing of the product produced in the first stage. Thus, the concn. of chlorides in the washing liquid increases successively. On one hand, the by-produced chlorides are washed successively with a washing liquid contg. successively low content of chlorides to dissolve the chlorides, and washed finally with fresh water. Thus, undissolved chlorides and those sticking to an unreacted material are removed completely.

Title: Light emitting semiconductor modulator
Inventor: SHIRAI TADAO
IPC: H04B10/293
Filed: 1986-07-15
Abstract: PURPOSE:To stabilize the laser stimulated output within a pulse width by adding an L-C series circuit in parallel with a laser diode so as to oscillate the laser stimulated light at the resonance frequency of the L-C circuit forcibly. CONSTITUTION:A modulation voltage PL3 is fed to a laser diode (LD) 1 via a blocking inductance (L1)2 inserted in the circuit in series with the LD 1. A resonance capacitor (C) 4 and a resonance inductance (L2) 5 are connected in parallel with the LD 1. A pulse modulation wave is fed to the LD 1 via the inductance (L1) 2 blocking the oscillating current of the PL 3. Thus, harmonics included in the pulse waveform are resonated in the resonance circuit C-L2, in which a resonance current flows and the modulation pulse and the resonance frequency are superimposed on the bias modulation current. Thus, the output instable element in the LD 1 is made stable because of the forced oscillation.

Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of molten metal from a nozzle touching surface and the back flow of the molten metal to a cylinder side and to improve the safety and the producing stability by detecting the temp. of a sprue bush in a die and stopping the injecting movement when the raising amount of the temp. per unit time becomes not less than the preset value before the injection. SOLUTION: Thermocouples 3, 6 are disposed to the sprue bush 5 and/or a nozzle 1 in the die to detect the temps. of the sprue bush 5 and/or the nozzle 1. When the temp. of the sprue bush 5 quickly raises before the injection, it is judged that the molten metal flows into the die, and injecting movement is stopped. When the temp. of the nozzle 1 quickly drops before the injection, it is judged that the molten metal leaks from the nozzle 1 and the injecting movement is stored. In the case of setting the thermocouples 3, 6 to near a runner, since the good sensibility is obtd., this is desirable. In the case of being a shifting formation, it is desirable to measure the temp. change at a fixed time after again pushing the nozzle 1 to the die.
