Title: Production of silicon nitride-silicon carbide composite sintered body
Inventor: ISAKI HIROMASA
IPC: C04B35/584
Filed: 1988-05-26
Abstract: PURPOSE:To obtain the title composite sintered body having excellent fracture toughness and strength by sintering the mixed powder of the silicon nitride and silicon carbide formed by hydrolyzing a silicon alkoxide at a specified temp. under pressure. CONSTITUTION:The mixed powder of the silicon nitride and silicon carbide obtained by hydrolyzing a silicon alkoxide and contg. <=40wt.% silicon carbide is sintered at 1550-1730 deg.C under pressure to obtain the desired composite sintered body. Sintering under pressure must be applied to obtain the desired composite sintered body having excellent mechanical properties, and means such as hot pressing, gaseous-pressure sintering, HIP, and extra-high-pressure sintering are applied for the pressurization. When sintering is carried out at <=1550 deg.C, a dense sintered body is hardly obtained, and hence a sintered body having excellent mechanical properties is not obtained. When the sintering is carried out at >=1730 deg.C, a dense sintered body is obtained, however the grains are grown, the bonding state at the interface is changed, and the strength and fracture toughness are unfavorably decreased.

Abstract: PURPOSE:To obtain stable commutating operation in a commutatorless motor by obtaining a frequency signal proportional to the frequency or rotating speed of an armature voltage, adding it to a signal proportional to the phase deviation to continuously comparing the phase with sinusoidal data, thereby obtaining the phase detection at high accuracy. CONSTITUTION:A frequency arithmetic circuit 101 which inputs a 3-phase output signal of a voltage detector 6 applies an analog signal proportional to the frequency of a 3-phase signal to an adder 102.

The output signal of the converter 11 is converted by a counter 12 into the phase theta of digital amount, and the phase theta is inputted to an ROM13 and an effective commutation leading angle beta setter. The sinusoidal signal corresponding to the phase theta outputted from the ROM13 is inputted through a D/A converter 9 to the circuit 8, and the output signal from the beta setter becomes a reference signal for commutation timing.

Title: Hydraulic mechanism level detector
Inventor: NAKADA KIYOSHI
IPC: F03B15/14
Filed: 1977-10-26
Abstract: PURPOSE: To keep accurate level of a water level detector free from detection error caused by direct coming or mixing of water or bubble in the water level detector, which flows through a bypass provided between an upper and a lower communication pipe.  
     CONSTITUTION: A lower communication pipe 14 has a bubble separating chamber 16 whose opening 13 is communicated with a level detector 8. A bypass 17 is furnished between the bubble separating chamber and the upper communication pipe 12. Even if the water in a suction-out pipe 10 flows into the upper communication pipe 12, it bypasses through the bypass pipe 17, runs through the bubble separating chamber 16 and the lower communication pipe 14, and flows out from the opening 13. The bubble coming from the lower communication pipe is separated from water by the bubble separating chamber., passes through the bypass and the upper  communication pipe, and is released into atmosphere so the water level results to lower. As water or bubble does not directly flow into or mix with the water in the water in the water level detector 8, the level of it may be kept constant. There is not a level difference.
