Title: Production of fine silicon nitride powder
Inventor: IMAI ISAO
IPC: C01B21/068
Filed: 1989-02-08
Abstract: PURPOSE:To obtain fine silicon nitride powder without carrying out pulverization for a long period by heat-treating silica powder in a mixed gas of NH3 and a hydrocarbon, pulverizing the heat-treated powder and further heat-treating the pulverization treatment product in a specific mixed gas. CONSTITUTION:Silica powder is heat-treated in a mixed gas of NH3 and a hydrocarbon at 800-1400 deg.C. The resultant product is then subjected to pulverization treatment. The obtained pulverization treatment product is further heat- treated in NH3 gas or a mixed gas of NH3 and at least one of the hydrocarbon, CO and an inert gas at 1200-1600 deg.C to afford the objective fine silicon nitride powder. The above-mentioned pulverization is carried out for 5-10hr if, e.g. 30g substance to be pulverized, together with 4kg balls having 16mm diameter, is charged into a ball mill having 160mm inside diameter and 4.8l internal volume. If the aforementioned heating temperature is <1200 deg.C, silicon nitride having the complete crystal structure and stoichiometric ratio is not obtained. If the temperature exceeds 1600 deg.C, contamination of fibrous silicon nitride is increased. Both cases are not preferred.

Abstract: PURPOSE:To put off an exposure lamp forcibly when the lamp is abnormally lit up by providing a moving detecting device that detects relative movement of an optical system and an original. CONSTITUTION:The output end of an NAND circuit 42 is connected to the set input ends of a triggerable monostable flip flop 46 through a differentiation circuit consisting of a resistance R2 and a capacitor C1. The output end Q of the monostable flip flop 46 is connected to another end of an NAND circuit 43, and the output end is connected to an exposure lamp driver 47. Output of the monostable flip flop 46 becomes off after lapse of time t1 after monostable trigger after passing an optical system carriage at the time of second copying. This time t1 is the set time of the monostable flip flop 46, and this is set longer than maximum time of exposure and sufficiently shorter than the time up to damage of an original placing plate 2. Accordingly, even when the exposure lamp is kept on by some reason, it is put off forcibly after lapse of set time t1 of the monostable flip flop 46, and damage of the original placing plate 2 can be prevented.

Abstract: PURPOSE:To economize energy by forming the swash-plate angle displacement instruction by obtaining the deviation of the revolution speed of a motor from an instruction speed and treating the deviation signal with a deviation signal and adding the signal obtained by multiplying the revolution speed by a certain gain, onto the above-described deviation signal. CONSTITUTION:The deviation between the revolution-speed instruction of a motor and the actual revolution speed of the motor is obtained at an addition point 113, and the deviation signal is sent into a min. value selecting device 109 through a limiter 112 and an absolute-value function 111, and compared with a power controlling signal 110, and the less value is selected. Further, the signal obtained by multiplying the actual number of revolution 101 of the motor by a certain gain G102 is added at an addition point 106, and thus the swash-plate angle displacement signal is formed. Therefore, when the max. value of the limiter 112 is set so that the piping pressure does not exceed a relief pressure, a relief valve does not operate on acceleration and deceleration of the motor, and energy economization is permitted.
