Title: Optical disk
Inventor: OKADA OSAMU
IPC: G11B7/24
Filed: 1989-07-19
Abstract: PURPOSE:To suppress the warpage of a substrate by forming a thin film consisting of ceramics or metal on a surface on which a magnetic recording film is not formed. CONSTITUTION:The films of SiN, TbFeCo and SiN, etc., are continuously formed as the magneto-optical information recording medium film 13 on a polycarbonate substrate and a protective coat 14 is applied thereon. For example, an SiO2 film is formed as a back coat film 12 on the part where the recording medium film 14 is not formed. Further, the coat 14 is applied on the film 12. The conditions for the infiltration and desorption of moisture on both surfaces of the substrate are uniformized by forming the back coat film in such a manner. The stresses occurring in moisture absorption are, therefore, eventually offset each other in the parts of the back coat film and the medium film and the warpage of the substrate is suppressed.

Title: Directional control valve
Inventor: ISHIZAKI NAOKI
IPC: F15B11/08
Filed: 1994-08-05
Abstract: PURPOSE:To provide a compact directional control valve without requiring any piping by blocking return oil from a holding pressure generating chamber of a hydraulic actuator from flowing in a tank by a meter out valve having a cone sheet type sheet part when a main spool is at its neutral position. CONSTITUTION:A spool 54 is pushed rightwardly by a centering spring 68 and a sheet surface 62 is pressure welded to a sheet receiving surface 61 as pilot pressure oil is not acted to a second receiving pressure chamber 48 when a main spool 40 is at its neutral position. Holding pressure in a second chamber 73 of the hydraulic actuator 71 flown in a first oil chamber 56 is shielded so as not to flow in a second oil chamber 57. At this time, as a sheet surface 62 and a sheet receiving surface 61 are taper shaped and cone sheet type sheet parts, natural falling of the hydraulic actuator 71 can be prevented without any oil spillage. As a meter out valve 44 is mounted in a valve body 30 and also the sheet part is opened by pilot pressure oil for switching a main spool 40, fitting space can be reduced and piping is not needed.

Title: Dc welding device
Inventor: HAYASHI TETSUO
IPC: B23K9/06
Filed: 1980-12-24
Abstract: PURPOSE: To improve the drooping characteristics of output current by connecting two pieces of shunts in series, connecting two pieces of diodes to one of these, and supplying the voltages between switching transistors and shunts to a control circuit.  
     CONSTITUTION: In the period t 1  while a switching transistor 5 is conducting, electric current flows to a shunt 7 like an arrow 44, and negative voltage 46 is generated. In the period (t) when both switching transistors 5, 6 go non-conducting in succession to this state, the current flows to a shunt 40 like an arrow 48, and negative voltage 50 is generated. Both these voltages 46, 50 are added and are averaged with respect to the period T in a control circuit 22. Since the average voltage is larger than conventional average voltage, the drooping characteristics are improved. Hence, it is possible to keep the output current during welding within the current rating of the TRs 5, 6, and the TRs 5, 6 are protected.

Title: Belt-driven dubbing deck
Inventor: MIYAZAKI TOMOHIRO
IPC: G11B5/86
Filed: 1984-09-05
Abstract: PURPOSE:To prevent the variation of sound quality for slave tapes obtained by dubbing by using a common motor and a common belt for the even drive of capstans which drive tapes for reproduction and recording respectively. CONSTITUTION:Both capstans 2 and 3 for the reproduction and the recording respectively are driven by the common motor 1 and the common belt 4. Thus both recording and reproducing tapes are revolved evenly and held between both capstans 2 and 3 and a pinch rollers to be sent out. The belt 4 is hooked to capstans 2 and 3 and a motor shaft 1 via pulleys 5 and 6 at a satisfactory angle that causes no slip. Therefore both capstans 2 and 3 are revolved at an exactly equal revolving speed. Furthermore the variances of both tape driving speeds are coincident with each other in terms of time despite the generation of the revolving variance proper to the motor 1. This prevents the deterioration of the wow and flutter of the sounds reproduced from slave tapes as well as the variation of sound quality.
