Filed: 1987-11-19
Abstract: PURPOSE:To simplify a photoetching process, by forming a resistance region with the ion implantation prior to the formation of an emitter region and forming even a base region by ion implantation as well. CONSTITUTION:Boron which forms a resistance region 28 as well as the base region 29 of an NPN transistor is ion-implanted by making use of a first resist pattern 27. Then, a second resist pattern 30 is formed and boron is again ion- implanted in the base region 29 of the NPN transistor by making use of the first resist pattern 27. As soon as an emitter region 33 is formed by diffusing selectively N-type impurities, heat-treatment is carried out at once so as to control hFE of the NPN transistor. As emitter diffusion of the NPN transistor is performed after forming the resistance region 28 by ion implantation, surplus heat-treatment is removed after forming the emitter region 33 and a photoetching process is simplified as well.

Filed: 1990-10-29
Abstract: PURPOSE:To prevent the blackening of a pseudo halftone image by performing the conversion of a noted picture element while selecting the recording dot pattern from among respective stored recording patterns into which the noted picture element is converted based on the arrangement of the black picture element near the noted picture element. CONSTITUTION:A noted picture element signal and a nearby picture element signal, for example, eight picture element signals near the noted picture element are read out in order from an original image signal storage part 1 to be supplied to a recording dot pattern selection part 2. On the conversion of the noted picture element into the recording dot pattern from the state of the picture element near the noted picture element to the recording dot pattern, the recording dot pattern selection part 2 generates the pattern identification signal for the selection of the optimum recording dot pattern to be supplied to a recording dot pattern storage part 3. In the recording dot pattern storage part 3, for example, eight recording dot patterns are stored, and the recording dot pattern to be read out is selected by the pattern identification signal from the recording dot pattern selection part 2. Thus, the blackening of the pseudo halftone image is prevented since the conversion into the proper black area from the original picture element to the recording dot pattern can be performed.

Title: Output controller for semiconductor laser element
Inventor: YUASA MASAMI
IPC: G11B7/126
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To attain precise record even when laser output of a semiconductor laser element used as a light source is low by superposing a high frequency signal on the drive signal of the semiconductor laser element at the recording time and obtaining a fixed output. SOLUTION: At the recording time, only a recording mode signal Write is inputted to an OR circuit 11, and a switch 12 is closed. Thus, a high frequency superimposition module 14 is turned on, and a high frequency signal is sent out from the high frequency superimposition module 14 to the semiconductor laser element 17 through a capacitor C. Then, a relatively high drive current flows to the semiconductor laser element 17 at the recording time, and the high frequency signal is superposed on the drive current. In such a manner, the laser output from the semiconductor laser element 17 doesn't cause resonance due to interference by high frequency superposition even when return light from an optical disk is made incident, and thus, the nearly fixed laser output by a pulsating current is obtained.

Title: Reactor control rod guide tube
Inventor: SUDA YOSHITAKA
IPC: G21C7/14
Filed: 1992-10-07
Abstract: PURPOSE:To suppress the irradiation growth of control rod guide tubes by using Zr base alloy having extension remaining stress at a certain range in circumferential direction of a tube. CONSTITUTION:In a conventional Zr base alloy tube having almost no remaining stress, circumferential remaining stress is generated by roll correction, tension correction, press correction and the like. If the extension remaining stress is below 3kg/mm<2>, irradiation growth can not be well suppressed. And if it exceeds 10kg/mm<2>, local dimensional variation and cracks are apt to be generated and the guide tube tends to be defective. Thus the extension remaining stress added in circumferential direction is specified within 3 to 10kg/mm<2>.
