Title: Silicon nitride composite body
Inventor: SAKAI TAKENOBU
IPC: C04B35/584
Filed: 1987-11-11
Abstract: PURPOSE:To greatly improve a fracture toughness value and to obtain an silicon nitride composite body adequate as mechanical structural parts by dispersing ceramics whiskers provided with zirconia coating layers on the surfaces into a silicon nitride matrix. CONSTITUTION:The coating layers of zirconia (ZrO2) are provided on the surfaces of the ceramics whiskers of the silicon nitride composite body formed by dispersing the ceramics whiskers into the silicon nitride (Si3N4) matrix. Silicon carbide (SiC) whiskers, carbon (C) whiskers, etc., are usable as the ceramics whiskers. The ZrO2 transfers from the cubic crystal to the monoclinic crystal at about 950 deg.C in the cooling process from the sintering temp. and expands in volume during this time. The thickness of the coating layers of said ZrO2 is preferably specified to 40-140mu. The reason for such limitation lies in that the effect of improving the fracture toughness value is small if the layers are too thin and that the fracture toughness value is degraded on the contrary by the excessive influence of the ZrO2 if the layers are too thick.

Title: Capacity-adjusting method of reciprocating compressor
Inventor: KANETAKA ISAMU
IPC: H02P21/18
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To enable capacity adjustment in a wide range by changing the number of revolution by changing numbers of poles in the loaded state of compressor. SOLUTION: In the case of acceleration by changing (A) numbers of poles, a current is applied to a winding for low speed and acceleration is performed (applying S1 low speed winding current), until the different between high-speed output torque and low-speed output torque becomes larger than load torque. A current is applied to a winding for high speed (applying S2 duplication current), and the current flowing in the low speed winding is cut off (applying S3 high-speed winding current). In the case of deceleration by changing numbers of poles (B), the current flowing in the high-speed winding is cur off (S4 power source breaking/speed detection) during high-speed operation, while detecting the rotational speed from the state of current applying to the high-speed winding.  When the rotational speed is reduced to be approximately equal to the synchronous speed at the time of low-speed rotation, a current is applied to the winding for low speed (applying S5 low speed winding current). As a result, the number of revolution is changed by changing the numbers of poles in the loaded state of compressor, and capacity can be adjusted in a wide range.

Title: Image forming device
Inventor: ITAKURA HARUO
IPC: G03B27/50
Filed: 1989-11-01
Abstract: PURPOSE:To surely prevent hitting on a home position side without dropping copy productivity by measuring a current value of an optical system driving motor when an optical system is returned, resetting the limit threshold of a current limiter when the measured current value is a prescribed or below, and changing the characteristic of the motor. CONSTITUTION:A control part 14 is provided with a CPU 15, a RAM 16, and a timer 17, a reference current value to judge the amount of the driving current of an optical motor M, the limit threshold of the current limiter 22, etc., are stored in the RAM 16. In this case, when copying is executed, the temperature of the motor rises, and when the resistance of a coil increases, a motor driving current value decreases. When the scanning speed and damping characteristic of the optical system changes, the limit threshold of the current limiter 22 increases, and the ceiling value of the current increases. Therefore, an optical system return speed which drops caused by the rising of the temperature and brake damping characteristic can be compensated. Thus, an optical system is effectively reduced by a reversal brake, so that hitting on a home position side is prevented.
