Title: Nonlinear optical material and its production
Inventor: OYOSHI KEIJI
IPC: G02F1/355
Filed: 1992-07-21
Abstract: PURPOSE:To enhance a nonlinear sensitivity and to shorten the relaxation time by forming phosphorus particulates on the surface layer of a light electrode substrate or light transparent thin film. CONSTITUTION:A quartz glass substrate 1 subjected to specular finishing is prepd. and is immersed for one minute in an aq. hydrofluoric acid soln. in order to remove the stains on the surface of the substrate 1; thereafter, the substrate is subjected to a washing treatment. This substrate 1 is irradiated with phosphorus ion beams 2 with accelerated energy by using an ion implantation device. The addition of the phosphorus by ion implantation acts to enable the formation of the particulates at a higher density than by a heat treatment precipitation method as the phosphorus can be supplied to the light transmissive substrate or the light transmissive thin film at the solid solubility or above in such a case. The formation of the particulates by the ion implantation acts to form the amorphous phosphorus particulates. The amorphous phosphorus particulates act to shorten the relaxation time of the nonlinear effect.

Title: Optical head
Inventor: SATO MASAYASU
IPC: G11B7/085
Filed: 1987-08-03
Abstract: PURPOSE:To execute accurately and smoothly the locating of an objective in a track control and an access control by providing a means to speedily rotate a guiding shaft member for constantly maintaining a carriage and the guide shaft member relatively in a dynamic condition. CONSTITUTION:By the high-speed rotated of a motor 20, a pulley 21 fitted to the rotating shaft of the motor 20 is rotated, and the rotation is correctly transmitted to guiding shafts 19a and 19b. At such a time, the peripheral surface of the pulley 21 has an elastic member 22 in order to damp a minute high frequency oscillation generated from the motor 20, etc., and to maintain a contact condition with the guiding shafts 19a and 19b constant. Thus, since, between sliding shaft bearings 18a and 18b and the guiding shafts 19a and 19b, a carriage 17 can be activated by overcoming a dynamic friction force much smaller than a static friction force, the carriage 17 is immediately activated even by a weak current and smoothly moved in a shaft direction. Thus, the locating control of the objective at the time of the track control and the access control can be accurately and smoothly executed.

Title: Decurl mechanism and recording device using decurl mechanism
Inventor: SASAI KEIZO
IPC: B65H16/02
Filed: 1989-07-27
Abstract: PURPOSE:To make curl correction according to the curled degree of a roll sheet by moving a guide member or a decurl member by the mutual action between tension applied to a sheet material and moving force supplied to the guide member of the decurl member. CONSTITUTION:At the time of conveying a sheet material, a shifting means 26 stops in the balanced state between tension applied to the sheet material and energizing force by an energizing means 35. Accordingly, when the tension is large, the influence of the energizing force to the shifting means 26 is small, and the acting quantity of the shifting means 26 becomes small and therefore the curvature of the sheet material becomes small. On the other hand, when the tension is small, the moving quantity of the shifting means 26 becomes large, and the curvature of the sheet material thereby becomes large. Curl correction corresponding to curl strength can be therefore made. In this case, the moving quantity of the shifting means 26 is larger than the energizing force of the energizing means 35, so that the shifting means 26 is actuated against this energizing force in such a direction that the sheet is uncurved.

Title: E/o array optical power control system
Inventor: FUJIMOTO TAKASHI
IPC: H04B10/572
Filed: 1990-07-23
Abstract: PURPOSE:To inhibit variation of transmission delays produced by the difference between optical outputs by equalizing variations of optical powers produced when setting laser diodes in array based on the input of a reference level common to pulse current drive circuits. CONSTITUTION:When a common reference level VR2 is inputted into a common control input terminal 11, this input forces modulation control voltage V2+ or -DELTAV2 to turn to V2proportional i2+ or -betaDELTAi2 when the modulation data input signal VD to be inputted into an input terminal 5 indicates logical 'H' level. In the case of logical 'L' level, the aforesaid control voltage turns into V2+ or -DELTAV2 0. The electric current under the voltage flows into a pulse current drive circuit 23 where the optical output power of a laser diode 4 is controlled by the reference level VR2 to be inputted into the common control input terminal 11. This common control input terminal 11 is distributed into a laser diode drive circuit 2-1, a drive circuit 2-2, and a drive circuit 2-N of an E/O array 1. This distribution makes it possible to equalize all the optical output power of a laser diode 4-1, a laser diode 4-2, and a laser diode 4-N. It is, therefore, possible to inhibit the generation of variation of transmission delays caused by the differential optical output power.

Title: Method and device for transfer of pellet
Inventor: SAKOTA SHIGEO
IPC: H01L21/50
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To enable pellet transfer of highly accurate transfer position without damage to a pellet, etc., by transferring a pellet while sucking and holding it from a lower side by using a handling arm with a plurality of suction holes whose caliber is larger than a width of a pellet to be transferred. SOLUTION: A pellet 1 is sucked and held from below by using a handling arm 6 with two suction holes 13 whose diameter is larger than a pellet width size in a CCD linear sensor die bond device. Since the pellet 1 is held by using suction force of air which flows into the suction hole 13, a pellet can be held even if mutual positions shift a little if a pellet is inside a diameter of the suction hole 13. Therefore, highly precise positioning is unnecessary and there is no possibility that the pellet 1 is damaged. Furthermore, since a size difference in a width of the pellet 1 is allowable in some range, change of transfer is not necessary when the type is changed.
