Title: Optical reproducing system and device and optical recording carrier
Inventor: MORIYA MITSURO
IPC: G11B7/24
Filed: 1994-03-04
Abstract: PURPOSE:To provide the optical reproducing method and device and optical recording carrier capable of increasing the information density of the reproduction only optical recording carrier. CONSTITUTION:This recording carrier is composed of a substrate 305 formed with rugged information pits 301 and a thermosensitive material film 307 formed thereon. This thermosensitive material film 307 has the characteristic that its reflectivity falls when a temp. rises and that the original state of the high reflectivity is restored when the temp. falls. Heat is confined in the pit 301 parts when the recording carrier is irradiated with a prescribed light beam power 304 at the time of reproducing the information. The temp., therefore, rises and the thermosensitive material film 307 on the pit 301 parts attains the low reflectivity state. The radiation of the heat is high in flat parts 302 between the pits 301 and the pits 301 and, therefore, the temp. elevation is low and the state of the thermosensitive material film 307 does not change. Then, the quantity of the light reflected from the top of the pits 301 parts irradiated with the light beam 304 is more decreased and the amplitude of reproduced signals is increased.

Title: Inverter
Inventor: NISHIMURA HIROMICHI
IPC: H02P3/24
Filed: 1994-03-04
Abstract: PURPOSE:To stop an a.c. motor in a short time by producing d.c. braking stop command output when current shifts from a stable state to an unstable state in d.c. braking, and exerting braking force with reliability until the a.c. motor is about to stop. CONSTITUTION:Direct current braking command output is produced by a PWM generator 29, and braking force is exerted on an induction motor 24. Though the current I largely fluctuates in the early stage of braking, it stabilizes in the middle stage. At this point a rate-ofchange detector 38 detects that the fluctuation in the current I has fallen below a specified value. The value of current I is stored in a stable value storing means 39 as the stable current I0. When brought into an unstable state in the last stage the current I become smaller than I0. Therefore, a comparator 40 produces d.c. braking stop command S0 output through a d.c. braking command changing means 33B. This stops the d.c. braking command output from the PWM generator 29, and thus stops the induction motor 24.
