Title: Synthesis of silicon nitride
Inventor: SATOU KIMIHIKO
IPC: C01B21/068
Filed: 1981-04-21
Abstract: PURPOSE: To prepare powdery silicon nitride, in high yield, by the high-temperature reaction of a silicon halide with NH 3 , by burning a specific element in the reaction system when the reaction product is amorphous, and carrying out the reaction using the heat of combustion.  
     CONSTITUTION: In the reaction of a silicon halide (e.g. SiCl 4 ) with NH 3  at high temperature, H 2  and Cl 2  are introduced into the reaction system, and when the reaction product is still in an amorphous state, the H 2  and Cl 2  are burnt and the heat of combustion is utilized for the reaction. Preferably, these raw materials are charged in two times to prevent the remaining of halogen in the produced silicon nitride essentially completely. The first stage reaction is terminated in the stage of formation of the amorphous reaction product, and the production of the α-crystal is carried out at the second stage reaction. The second stage reaction is carried out in an N 2  and/or NH 3  stream at 600W1,700°C to obtain a halogen-free silicon nitride. There is no sticking of the produced silicon nitride to the reaction apparatus in the first stage reaction in contrast with the conventional process, and the recovery of the silicon nitride can be improved.

IPC: G01J3/433
Filed: 1984-03-28
Abstract: PURPOSE:To improve measuring accuracy, by performing modulation by using a signal having a waveform, in which a flat parts or parts that are changed slowly, thereby suppressing a parasitic spectrum, whose pitch is shorter than that of an absorption spectrum. CONSTITUTION:When a section, whose amplitude density is large, is included in a modulating waveform, response to a periodic parasitic spectrum, whose pitch is shorter than the width of an absorption spectrum line, is increased. Therefore, slowly changing parts are removed from the modulating waveform of a semiconductor laser. Figure (a) shows the periodic waveform having a peaked top part. The top part is made to be a sharp point. In Figure (b), a ramp signal having a small amplitude is superimposed on the modulating waveform as an additional signal, and the stepwise change is eliminated. In Figure (c), a pseudo-random signal is superimposed on the waveform in Figure (a), and the excellent result can be obtained.

Filed: 1993-03-19
Abstract: PURPOSE:To improve the efficiency of slip read processing and read data output processing in the character reader for successively reading character information on the plural kinds of media such as slips concerning those media and successively outputting the read character information. CONSTITUTION:The upper limit sheet of media to be outputted at every kind of media is set to a memory 8 corresponding to the storage capacity of a means for storing the character information. The kinds of media read by a slip reading part 2 are successively identified by a slip identification part 3.

Filed: 1989-03-13
Abstract: PURPOSE:To eliminate the need for an A/D converter with high accuracy and to make the characteristic stable by employing a digital filter and an analog amplifier receiving a signal amplified by an analog amplifier using an automatic gain control circuit (AGC) and whose characteristic is stable even when ambient temperature changes. CONSTITUTION:An input signal is amplified by an analog amplifier 1 set with the AGC circuit 5 and the signal level is increased, then the signal is converted into a digital signal by an A/D converter 2. Thus, the quantization error is less relatively and much accuracy is not required for the A/D converter 2. Since the analog amplifier 1 subject to quantization compensation and a digital filter 3 are immune from a change in ambient temperature, even when ambient temperature is varied, the characteristic is made stable. Thus, the line equalizer not requiring the A/D converter with high accuracy and whose characteristic is stable even when ambient temperature is changed is obtained.
