Title: Optical system driver
Inventor: MIYAJIMA GIICHI
IPC: G11B7/08
Filed: 1985-08-09
Abstract: PURPOSE:To correct the fall of the optical axis of an optical axis to be driven and to secure instantaneously the coincidence between said corrected optical axis and the optical axis of another optical system, by supporting an optical system holder with a spherical bearing and securing the smooth change of the angle of the optical axis. CONSTITUTION:An optical system 4 is held by a lens holder 11 and the holder is supported by a spherical bearing 12. Thus, the system 4 can be shifted toward its optical axis and this optical axis can be tilted in an optical direction. When the coils 13 and 14 welded at both ends of the bearing 12 are energized, both coils receive the force in the direction Y orthogonal to the optical axis of the system 4 by the interaction of magnetic fields between permanent magnets 20 and 21. Then the holder 11 moves in the direction Y by said electromagnetic force. While coils 15-17 are energized for each or every two pieces for generation of the electromagnetic force in the directions opposite to each other. Thus the holder 11 can be tilted in the desired direction by the moment of revolution.

Abstract: PURPOSE:To execute cold rolling with high efficiency without generating deformation at the time of final annealing by starting the cold rolling of an austenitic stainless steel in a specific temp. range controlled by the equiv. of Ni and adequately suppressing the content of martensite. CONSTITUTION:The material is preheated from an initial pass and the rolling is started at 50-250 deg.C material temp. and at the temp. above the straight lines (a), (b) shown in the figure by the Ni equiv. Nieq=Ni+0.65Cr+0.98Mo+1.05Mn+0.35Si+12.6C of the alloy at the time of subjecting the austenitic stainless steel such as 18Cr-8Ni steel to cold rolling. The cold rolling is further executed by suppressing the content of the martensite before the final annealing to <=20%. The cold rolling of the material is thereby executed with high efficiency under the high reduction. In addition, the rolling of the above-mentioned material to a lighter gage is possible and the generation of the deformation at the time of the final annealing is obviated.

IPC: H01S5/00
Filed: 1986-07-24
Abstract: PURPOSE:To reduce junction capacitance within a semiconductor laser and realize ultrahigh-speed modulation without using dielectric film such as SiO2 by forming a high resistance semiconductor layer to a single side of reverse mesa projection of a semiconductor multilayered film substrate which is left only almost at the center of semiconductor multilayered film. CONSTITUTION:An N-InP buffer layer 3, InGaAsP active layer 1, P-InP clad layer 4 and P-InGaAsP contact layer 5 are sequentially formed on a semi- insulating substrate 2. The projection at the center is formed as the inverse mesa type and the electrode metals 6 and 7 are separated by a vapor deposition process. In the case of this structure, the InGaAsP 1 is surrounded by a high- resistance semiconductor layer 9 or a little amount of N-InP layer 10. Therefore, a signal current injected from the electrode metal 6 almost flows into the InGaAsP active layer 1 and the structure shows excellent response to high frequency. Thereby, parasitic capacitance within the semiconductor laser can be removed and since dielectric film such as SiO2 etc. is not used, ultrahigh- speed semiconductor laser device having modulation band of 10 GHz or higher and excellent reliability can be obtained.

Title: Memory area control system
Inventor: YOSHIKAWA MASAZUMI
IPC: G06F12/02
Filed: 1987-07-13
Abstract: PURPOSE:To reuse a memory area at a high speed by checking the generation areas having data exceeding the prescribed capacity and carrying out the copying processes at one time to all generation areas having the generation numbers smaller than the generation having the smallest number and the quantity of data smaller than said capacity excluding a generation 1. CONSTITUTION:A produced area 11 is short and a copying process is started. Here the area application value of a generation 2 exceeds its capacity and therefore the copying process is started to both generations 1 and 2. While the application value of a generation 4 exceeds its capacity and the application value of a generation 3 is less than its capacity. Therefore no copying process is started to the generation 4. In other words, the copying process is started to those generation areas having the generation numbers less than 3.
