Title: Carrier unit for data storage medium
Inventor: NARISHIMA TORU
IPC: G11B15/68
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a carrier unit for data storage medium low in cost without necessitating the complicated servo control and capable of detecting the moving speed or the moving position of a transfer part for the data storage medium. SOLUTION: The moving speed of the transfer part 104 for the data storage medium is subjected to an open loop control by controlling the speed of a DC motor 3 by a PWM control circuit 18. Also, a rotational position detecting body 14 is attached to a rotary shaft 6 of a power transmission mechanism 4, then the number ΔC of detected pulses representing the actual moving speed of the transfer part 104 for the data storage medium is obtained by an optical sensor 15. Further, the presence of an abnormality in the actual moving speed is judged by whether the number ΔC of pulses representing the actual moving speed is in the reference speed range C1-C2 or not. Since the moving speed of the transfer part 104 of the data storage medium is controlled by the PWM control to the DC motor 3, the manufacturing cost is reduced as compared with the case a high priced servo motor is used, and also the actual moving speed is detectable since the rotational position detecting body 14 is attached to the rotary shaft 6.

Title: Self-injecting synchronous semiconductor laser
Inventor: TOMOSADA NOBUHIRO
IPC: H01S5/00
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the adjustment of the angle and distance of an external resonance mirror by providing an external resonator which outputs part of the output light of a semiconductor laser as outgoing light, and at the same time, makes the remaining part of the output light incident to an optical resonator in the semiconductor laser. SOLUTION: Reflected light is made incident to an optical resonator in a semiconductor laser 1 by means of a phase conjugating mirror 5. Meanwhile, since the phase of returning light 101a does not change, even when the distance between the mirror 5 which is an external resonant mirror and the optical resonator in the laser 1 varies, the selected wavelength of an external resonator 50 does not change. Therefore, the reflected light is made incident to the optical resonator in the laser 1, with the phase of the reflected light which is automatically made match with that of incident light by means of the phase conjugating mirror 5, even when the distance between the mirror 5 and optical resonator in the laser 1 is not strictly adjusted.  Consequently, the need for adjusting the angle and distance of the external resonant mirror 5 is eliminated, when the direction of the optical axis and phase of the reflected light are corrected by using the mirror 5.

IPC: H01G4/30
Filed: 1994-07-26
Abstract: PURPOSE:To provide a lamination contact bonding method of ceramic green sheets wherein sheet lamination material can be suitably fixed by pressure, without failure. CONSTITUTION:When sheet lamination material SS is fixed by pressure, the peripheral part where conductor layers are not present is pressed with upper die 1. While the pressed state is maintained, the central part where conductor layers are present is pressed with fluid pressure, via a stretchable film 3. Independently of sheet thickness, conductor layer thickness, the number of lamination layers, etc., the stretchable film 3 is brought closely into contact with the surface to be pressed by the effect of stretchability, so that the central part is wholly uniformly pressed by the fluid pressure. Thereby imperfect contact bonding and pressure unbalance are corrected, and the sheets are suitably fixed by pressure.
