Title: Piezoelectric porcelain composition and its production
Inventor: NAKAO RUI
IPC: H01L41/39
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric porcelain compsn. having improved sinterability and uniformity in sintering reaction and giving a grain diameter fit frequency used by incorporating CuO and MnO2 as subsidiary components into a compd. contg. Pb, Ti, Nd, Pt and Sm as a base. SOLUTION: This piezoelectric porcelain compsn. is based on a compd. represented by the formula (0.01<=x<=0.40, 0<α<1, 0<=β<1, 0<=γ<1 and α+β+γ=1) and contains CuO and MnO2 as subsidiary components by 0.05-2.5 wt.% and 0.05-2.0 wt.%, respectively, based on 1 mol of the base. It is excellent in sinterability, does not cause transition from triple wave oscillation to quintuple wave oscillation in thickness longitudinal vibration and can improve the temp. characteristics of the resonance frequency of fundamental waves in glide vibration. When ZrO2 is further incorporated as a subsidiary component, the grain diameter of the resultant sintered compact can be controlled.

Title: Optical communication system
Inventor: EGAWA YOSHIKAZU
IPC: H04B10/11
Filed: 1987-04-30
Abstract: PURPOSE:To prevent the contamination of an erroneous signal by providing a laser beam oscillator at the output side of one equipment in one and the same equipment, providing a photodetector on the input side of other equipment, coating the inner surface of an equipment case with a reflecting preventing film and executing the direct communication without passing through a cable. CONSTITUTION:For a part 1 of the body of a flying object used also as the outer case of a device in common, an inner surface is coated with a reflecting preventing film and equipments 2 and 3 are mounded in it. A laser beam oscillator 4 is mounted on the equipment 2 and a photodetector 5 is mounted on equipment 3 respectively. When a signal is transmitted from the equipment 2 to the equipment 3, the signal of the equipment 2, after it is converted to an optical signal by the laser beam oscillator 4, is radiated toward the photodetector 5 and the optical signal received there is converted and used to the signal necessary for the equipment 3. Thus, the contamination of the erroneous signal due to the reflecting light is prevented.

Title: Injection amount controller for fuel injection pump
Inventor: NAKAMURA TETSUYA
IPC: F02D41/00
Filed: 1984-05-23
Abstract: PURPOSE:To control injection amount always with high accuracy by installing an angular signal detector which can detect the minute angular pulses over several-thousands pulses per revolution onto a pump shaft and controlling an electromagnetic spill valve by counting the above-sescribed pulses. CONSTITUTION:An angular-signal detector 1 is equipped with a disc 101 made of nonmagnetic material which has, on the outer periphery, a magnetic member 102 for magnetic record which has the interval between a pair of magnetic poles of 10mum or so, and fitted and fixed onto the rotary shaft of a fuel injection pump. Each signal can be detected at each pump revolution angle, e.g., at each 0.03 deg. by detecting the magnetic member 102 by a magnetic head 103. Therefore, an electromagnetic spill valve (not shown in the figure) is opened by the signal at the n1-th of the standard position and closed by the n2-th signal, and the error due to the variation of revolution can be reduced to zero. Since the injection time in one time of the pump is 10 deg. or so, fuel injection amount can be adjusted withan accuacy of 0.3%.

Title: Developing method of plural-sheet copying method
Inventor: YAMAOKA TOSHIHIDE
IPC: G03G15/00
Filed: 1983-06-15
Abstract: PURPOSE:To prevent deterioration in picture quality due to a drop in latent image potential during plural-sheet copying operation by increasing the frequency of an AC bias gradually according to the drop in latent image potential during the plural-sheet copying operation, and decreasing the peak voltage gradually. CONSTITUTION:For example, an image for the 1st sheet in plural-sheet copying is developed by applying an AC bias with a +650V peak voltage which is generated by superposing a +250V DC voltage upon an AC voltage having a 400V amplitude and a 200Hz frequency. The frequency of the AC voltage is increased monotonously as the number of copies increases, and the DC voltage, on the other hand, is decreased monotonousy. For example, an image for the 30th sheet is developed by applying an AC bias with a +550V peak voltage which is generated by superposing a +150V DC voltage upon an AC voltage having a 400V amplitude and a 600Hz frequency. Thus, copies are taken by setting a control circuit 10 to prevent a decrease in image density and fogging. The picture quality is therefore prevented from deteriorating in the plural-sheet copying operation.

The part 21b engages with the part 14b in said position and the rotation of the hook 14 is prohibited by the member 21. Thus, the part 14a of the hook 14 is kept engaged with the hole 15a and the opening of an upper unit 35 is prevented.
