Title: Production of alpha-type silicon nitride
Inventor: NOZAWA YASUAKI
IPC: C01B21/068
Filed: 1987-01-07
Abstract: PURPOSE:To obtain the title high-purity alpha-type silicon nitride while simplifying the process and reducing the auxiliary equipment, energy, and work load, by mixing ammonium chloride into metallic silicon powder to nitride the silicon. CONSTITUTION:When metallic silicon powder is directly nitrided to produce silicon nitride, 1-15wt.% ammonium chloride is added to the silicon powder. The lump metallic silicon obtained by the reduction of quartzite with coke at high temp. in a conventional electric furnace is pulverized to 2-100mu, and the pulverized material can be used as the raw material metallic silicon. Ammonium chloride is added to the material, the mixture is mixed n a dry basis by the mixer such as a ribbon blender for about from 5min-3hr, the product is packed in a heat-resistant vessel and brought into contact with N2, NH3, or their gaseous mixture, and the nitriding reaction is carried out at about 1,000-1,500 deg.C for about 20-180min. By this reaction, the impurities such as Al and Ca are removed along with the exhaust gas prior to nitriding, and high-purity alpha-type silicon nitride can be easily obtained.

Inventor: SATO KOICHI
IPC: H04N5/18
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To adjust a clamp level by simple constitution. SOLUTION: A low-pass filter 70 smoothes voltage corresponding to the least significant bit of digital signals outputted from an A/D converter and outputs it to a sample-and-hold circuit 80. In the sample-and-hold circuit 80, sample-and-hold pulses are supplied to a switch 83 based on a timing signal outputted from a generator in an optical black period and the voltage of the least significant bit of a black level is outputted to a clamp level adjustment circuit 90. In the subtractor 91 of the clamp level adjustment circuit 90, when the voltage inputted from the sample-and-hold circuit is higher than 0 V, the voltage for which the voltage is subtracted from a reference voltage is outputted to a clamp circuit as a clamp voltage. In the case that an input voltage is 0 V, the clamp voltage is raised by a pull-up resistor R9 and outputted.

Title: Output circuit
Inventor: YAMADA KAZUMI
IPC: H03K19/013
Filed: 1985-01-11
Abstract: PURPOSE:To obtain a high speed output circuit by providing a clamp circuit so as to clamp a collector voltage of an output transistor (TR) to an optional level thereby preventing saturation of collector of the output TR. CONSTITUTION:When an input signal is fed to an input terminal IN, the input signal turns on a TRQ2, a diode D1 and an output TRQ1, undergoes clamping at a value of 3VF (where VF is a base-emitter voltage of TRs and an anode- cathode forward voltage of a diode) and is subject to a level shift of (2+R2/R3)VF by a level shift circuit comprising a diode D2, a TRQ3 and resistors R1, R2 and fed to a collector of the output TRQ1. On the other hand, when the input voltage is <=3VF, the TRQ1 is turned off, no current flows to the clamp circuit and the level of an output terminal OUT goes to high impedance. Then the base electric charge of the TRQ1 is discharged through the resistor R1.
