Title: Piezoelectric parts feeder
Inventor: FUJIMOTO KATSUMI
IPC: B65G27/24
Filed: 1987-01-12
Abstract: PURPOSE:To secure the parts transfer and lower the height by making an axis level and parallel and supporting one end with a supporting member and constituting it of sectionally multi-angle vibrator which is formed with piezoelectric element at each side in the above feeder for directly transferring electronic parts. CONSTITUTION:Equiphase voltage is applied to piezoelectric elements 20a, 20c opposed to a vibrator 16a and voltage having phase difference of pi/2 to the voltage to the piezoelectric elements 20, 20c is applied too piezoelectric elements 20b, 20b'. Hereby the vibration part 18a moves elliptically. Then, the amplitudes in the horizontal and vertical directions are individually changed by adjusting the maximum value of both applied voltages. And for the vibrator, the applied voltage to 16b is reversed to that to the vibrator 16a. Similarly, the vibration parts 18a, 18b can obtain the rotation in the same direction by applying the voltage to vibrators 16c, 16d too in the same way and parts on a receptacle 24 shifts along a groove 24a. By this constitution, the height is lowered and the parts can be surely transferred.

Filed: 1991-01-22
Abstract: PURPOSE:To obtain a circuit for detecting the low voltage side of a power supply voltage drop detecting level before detecting its high voltage side in a computer power supply voltage monitoring circuit for supplying power especially by battery driving. CONSTITUTION:Two power supply voltage levels are set up by both comparators 1, 2 and power supply alarm detection level signals 7, 8 are outputted. The minimum voltage value of power supply variation which is conventionally detected after the detection of an alarm detection level can be detected before the detection, and when the alarm detection is binarized, battery voltage in the continuous printing of a printer e.g. can be monitored. Consequently the drop of the battery voltage in the continuous printing can surely be detected and power supply forced OFF due to H/W can be evaded.

Title: Semiconductor light-emitting element
Inventor: SASAKI KAZUAKI
IPC: H01S5/042
Filed: 1992-01-17
Abstract: PURPOSE:To reduce necessity to implement growth on the order of an atomic layer with good controllability by involving another barrier layer in which multiquantum barrier structure is not matching a semiconductor substrate in a lattice. CONSTITUTION:First of all, a comparatively thick layer 31 of InGaAlP is grown on an active layer 13. After that, a well layer 40 of InGaP and barrier layers 35 to 33 of InGaAlP are alternately grown thereon. Each of those layers is matching a substrate of GaAs in a lattice. After the barrier layer 33 of InGaAlP is formed, a barrier layer 42 of InAlP is grown. The barrier layer 42 of InAlP is not matching the substrate of GaAs in a lattice. Thus, a multi-quantum barrier structure 100 has the barrier layer 42 of InAlP made of a semiconductor material which does not match the substrate of GaAs in a lattice. The barrier layer 42 has larger energy-band gap than the barrier layers 35 to 33 of InGaAlP, so that it acts as a barrier well enough against electrons having high energy even when it is not formed in a thin film.
