Title: Crystal growth method
Inventor: FUJIMOTO AKIRA
IPC: H01S5/00
Filed: 1985-02-28
Abstract: PURPOSE:To enable the growth of a required pattern shape growth layer consist ently with other layers by growing crystals irradiating the light corresponding to the pattern shape on the surface of a semiconductor substrate or a semicon ductor layer where the crystal is to be grown. CONSTITUTION:Since the temperature of a substrate 1 is lower than the temperature appropriate for accelerating crystal growth, the activating energy for crystal growth is insufficient. In the area which is irradiated with light 10, however, the insufficient energy is supplemented with the irradiated light and the crystal growth is accelerated so the speed of crystal growth in the area which is not irradiated with the light 10 is slower than the speed of crystal growth in the area which is irradiated with the light 10. Accordingly, an active layer 3 wherein the area irradiated with the light 10 is thicker and the area not irradiated is thinner is formed on a confinement layer 2, e.g., the active layer 3 which has a period structure of diffraction grating is formed.

Filed: 1987-02-24
Abstract: PURPOSE:To prevent rising of a voltage by combining an AC power having an inductance component with a DC power obtained by rectifying said AC power and by providing an overvoltage limiting circuit on the output side of a filter. CONSTITUTION:A three-phase AC of power supply 10 is rectified by a rectifier 12 and a DC output thereof is applied to and switched by a power FET 20 of switching element. An output of said FET 20 is smoothed by a filter 22 and supplied from output terminals 24, 26 to a load. Also, an error amplifier 16 compares an output voltage with a reference voltage 18 and outputs a PWM signal by a PWM circuit 30 to control the FET 20. Further, an overvoltage limiting circuit 32 removes a transient output voltage spike. In this manner, a calorific value can be controlled to a low one because an ON-resistance of said FET 20 is small, though heat is mainly generated by electric current flowing when the FET 20 is in ON-state.

Patent JP-H02221732-A (JP)
Title: Torsional vibration damper
Inventor: KANO SHIGEKI
IPC: F16F7/06
Filed: 1989-02-23
Abstract: PURPOSE:To make bulk torque transfer possible in a simple structure as well as to control the extent of torsional vibration by coupling both shafts at an axial edge on one side, forming a clearance in an axial edge on the other, and setting up a viscoelastic body in this clearance and then attaching it tight to a pair of shaft members. CONSTITUTION:When torque will not act, each relative angle displacement of a torque transfer shaft 10 and a hollow shaft 12 is zero because both shafts 10, 12 are coupled at the coupling side being shown as in X, but angular displacement is produced between both these shafts 10 and 12 at the noncoupling side being shown as in Y at the opposite side. This means that the hollow shaft 12 will not cause any angular displacement. Accordingly, when a viscoelastic body 13 is set up in this interval, this viscoelastic body 13 resists the angular displacement, whereby as if a side of the hollow shaft 12 works so as to check any torsion of the torque transfer shaft 10. Then, at normal static torsion, the viscoelastic body 13 is merely deformed to some extent, but when vibration has occurred, it acts so as to control this vibration. With this constitution, a torsional vibration is kept back, and any breakdown of the shaft can be thus prevented.
