Title: Laser light oscillation equipment
Inventor: SUTEN HERUMUFURIDO
IPC: H01S3/06
Filed: 1992-08-20
Abstract: PURPOSE:To eliminate noise of an Nd:YVO4 laser by controlling the length of a resonator and the birefringence of an element in the resonator. CONSTITUTION:A device consists of an Nd:YVO4 crystal 5 as the gain medium, and a KTP crystal 8 as the nonlinear optical medium for frequency conversion. An input coupling mirror 4 is arranged on the surface of the gain medium 5, and an output coupling mirror 10 is separated therefrom. The light from a semiconductor laser 1 whose light corresponds with the absorption band of Nd:YVO4 is converged to the gain medium 5 by a lens 3. In this case, the on.line.drift due to the birefringence of the Nd:YVO4 crystal 5 is compensated by temperature adjusting. The KTP crystal 8 always operates as a halfwave plate, and the total optical path-length of the resonator must be controlled, so that the temperature of the KTP crystal 8 and that of the Nd:YVO4 crystal 5 are independently controlled by two Peltier cooling devices 6, 9. Thereby the polarization and the phase mismatch of resonator mode can be controlled.

Title: Small-sized direct-current motor
Inventor: TANAKA KEI
IPC: H02K23/00
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the position of the contact between a brush and a commutator from being shifted for higher reliability, by forming a step at the outermost portion of the top of the caulking area in a resin bracket recess when caulking the resin bracket containing the brush and a bearing to a motor frame. SOLUTION: The outermost portion of the caulking area 2 in a resin bracket recess is lowered to form a step in the caulking area 2 in the resin bracket recess. The caulking area 1 on the circumference of an opening in a frame is bent toward the top of the caulking area 2 in the resin bracket recess, and the frame and the resin bracket are thereby caulked together. Thus the volume of the portion 3 of the resin bracket, dug as the result of the caulking of the frame and resin bracket, is reduced. In other words, stress exerted on the inside of the resin molded body is reduced, and distortion in the resin bracket is reduced. This obtains the positional stability of a brush and a commutator.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the concentrating input of consumption current by giving a time difference to the operation of a sense amplifier group for detecting read data and the operation of a sense amplifier group for detecting the read data. SOLUTION: A sense amplifier activation signal DE output from a pulse generator 1 and a latch timing control signal DL are input to a selector circuit 6. The select delay circuit 6 selects, delays and outputs the control signals via a low order address signal AD2 to be input from an address generator 19. The operating timing of the sense amplifiers 31, 32 and latch circuits 37, 38 are deviated in the phase from those of the sense amplifier 2, 3 and latch circuits 4, 5. Thus, a peak current value becomes two current waveforms of about half, the concentrating input of consumption current at the time of reading at a high speed can be prevented, and hence the corresponding power source capacity can be decreased.
