Title: Laser power control circuit and optical disc drive
Inventor: HAYASHIDA YOSHIE
IPC: G11B7/125
Filed: 2001-10-22
Abstract: PROBLEM TO BE SOLVED: To make the start quick after buffer under-run errors are eliminated. SOLUTION: This circuit makes the recording power constant by inputting the detected output matching the light amount of the laser diode. It has a low frequency amplifier 49 to determine the response of the control loop to control the laser power, and this amplifier consists of a differential amplifier 47 and a low-pass filter 48 to maintain the output voltage of the differential amplifier at the same value (target value) as the one immediately before a buffer under- run error happens when there is no data to write. Since the laser power control voltage is supplied to the laser driver without changing when writing data and when there is a buffer under-run error, the laser power control voltage rises quickly to the target voltage even when starting again to write the data, and the waiting time is shortened before the start of data recording.  Besides, the recording capacity is secured for the optical disk.

Title: Liquid crystal illuminator
Inventor: SATAKE TAKAO
IPC: G02F1/13357
Filed: 2001-10-26
Abstract: PROBLEM TO BE SOLVED: To form a light source device that emits light easily passing through the transmission axis of a polarizer attached to a liquid crystal display element. SOLUTION: This light source device (10) is constituted by attaching a light emission diode (12) to both side ends of a light guide rod (11) made of acrylic resins. Triangular grooves (100) are formed on the side face (11a) of the light guide rod, opposite to a light transmission plate, and the grooves are arranged at the same interval and are deeper as the grooves get far from the light emission diodes. When a refractive index is 1.49, the angle α of a first inclination surface (110) is set as α=32 deg.. Light reflected by the first inclination surface and made to emit vertically from the side surface (11b) of a light transmission plate is only an S wave, and light made to emit at other angles is an S wave in many cases. Even though the light is reflected at a prism array included in a prism (23) where mountains (23a) and valleys (23b) on the surface (22) of the light transmission plate respectively extend in an X direction and goes toward the liquid crystal display element through the polarizer, the light is inclined to go through the transmission axis of the polarizer because of many S waves.
