Title: Phase lock loop oscillator
Inventor: ITOU KENJI
IPC: G11B15/467
Filed: 1981-03-05
Abstract: PURPOSE:To minimize the error of delay, by constituting a phase locking means with a main monomulti using a digital counter and a slave monomulti using a CR. CONSTITUTION:A clock pulse CP is applied to a 16-bit counter 11 via an AND circuit 14, and the output of the counter 11 is supplied to latch circuits 15 and 16. The output of the circuit 16 triggers a monomulti 22 via a D/A converter 17 and an LPF19. The circuits 15 and 16 latch the contents of the counter 11 when the vertical synchronizing pulse V is supplied. When the phase of the pulse V is delayed, the delay time of the monomulti 22 is set by the contents which is previously latched to the circuit 16. Thus the error of delay can be reduced by increasing the ratio of delay time between a main monomulti consisting of the counter 11 and a slave monomulti consisting of the monomulti 22.

Abstract: PURPOSE:To keep off the unnecessary operation of a braking plate as well as to aim at improvements in reliability, by installing an orifice mechanism and the breaking plate in a cooling water discharge bypass pipe line branchedly connected to a cooling water discharge pipe line. CONSTITUTION:A cooling water plant inserts an orifice mechanism 21 alongside into a cooling water discharge bypass pipe line 9 at the upstream side of a breaking plate 10. During normal operation, even if transient pressure is produced inside a system and propagated up to the inside the cooling water discharge pipe line 9, it coolides with an orifice plate 22, receiving the pressure in the reverse direction by a reflecting wave produced at that time, and in consequence, a peak value of the transient pressure is buffered. Therefore, buffering the transient pressure produced inside the system, an equalized pressure wave in pressure distribution is possible to act on the breaking plate 10.

Title: Semiconductor laser unit
Inventor: NAMISAKI HIROBUMI
IPC: H01S5/00
Filed: 1978-03-22
Abstract: PURPOSE: To prevent the disturbance of an output light beam by making a sub- spot by scattering light away from a main spot appearing on a junction flank by curving the pn homo-junction surface.  
     CONSTITUTION: Viewing an unit from the upper surface, the pn junction surface J is made curved. Vibrating light is shut in along the curved line owing to a difference in refractive index around the junction. Crossing paths for vibrating light at right angles results in a slight loss caused by the curvature of paths. As a result, no scattering occurs near main spot M on the flank. Almost all of scattering light toward flank X is absorbed in p-type region 4a and will never appear at flank X. Scattering light toward flank Y, on the other hand, reaches the flank Y after passing through n-type region 4, but appears away from the junction end, where the main spot M is obtained, due to the curvature of junction J. Therefore, sub-spot S can be separated easily from main spot M by a mask, etc.
