Title: Production of magnetic recording medium
Inventor: YOSHIDA OSAMU
IPC: G11B5/66
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic film having excellent magnetic characteristics, corrosion resistance and electromagnetic conversion characteristics by carrying out vapor deposition of a Co-X alloy vapor deposition material having a specified atomic ratio of Co to X while releasing oxygen to form a Co-X-O magnetic film on a supporting body. SOLUTION: A supporting body 3 released from a supply roll 2a is traveled along a cooling can roll 1 and wound on a winding roll 2b. A vapor deposition material 5 is housed in a crucible 4 as the vapor deposition source. The material 5 consists of a Co-X alloy (wherein X is C, Si, P or B). When X is C, the alloy has 98:2 to 65:35 atomic ratio of Co:C. The material 5 is molten by an electron beam from an electron gun 8 to mix Co and X. A shielding plate 6 is used to control the incident angle so that the vaporized particles deposit on the supporting body 3. Further, oxygen is released from an oxygen gas supply nozzle 7 in the opposite direction to the rotating direction of the roll 1. Thus, a Co-X-O magnetic film is formed. Thereby, the obtd. magnetic film has excellent magnetic characteristics, corrosion resistance and electromagnetic conversion characteristics.

Title: Electromagnet
Inventor: KITAMURA TSUNEHIRO
IPC: H01F7/08
Filed: 1993-10-01
Abstract: PURPOSE:To suppress an electromagnet of low operation voltage by putting the rotation fulcrum part of a movable frame in such structure that it is abutted against and supported by the support of a yoke at three points at least with pressure. CONSTITUTION:When a current is not applied to a coil 2 for magnetization, the armature shoe 6b of an armature 5 attracts the magnetic pole face 3b of a fixed iron core 3 so that the magnetic flux by a permanent magnet 7 may form a closed magnetic path. When a magnetic flux is generated in the direction of negating the magnetic flux by the permanent magnet 7 by exciting the coil 2, the armature shoe 6a of the armature 5 attracts the magnetic pole face 3a of a fixed iron core 3 so that the magnetic flux being generated, with the coil 2 excited, may form a closed magnetic path. At this time, a movable frame 8 rotates in the condition that the apexes of three pieces of projections 81f, 81f, and 81f made at the contact sections with the support sections 4h and 4h of a yoke 4 are abutted against and supported by the support sections 4h and 4h of the yoke with pressure, at the rotation fulcrum parts 8f and 8f. Hereby, the movable frame operates stably, and thus this electromagnet does not require high operation voltage.

Title: Mold clamping device
Inventor: SHIMA YOSHIHARU
IPC: B29C45/67
Filed: 1987-09-30
Abstract: PURPOSE:To make the fore oil chamber of a mold clamping cylinder and a charge tank free from the application of pressure over the whole cycle and consequently make it possible to miniaturize and lighten a device by a structure wherein the mold opening and closing of a mold clamping device used in an injection molder and a die casting machine are done only by feeding pressure oil in the mold opening oil chamber and the mold closing oil chamber of a mold clamping ram and pressurizing said chambers. CONSTITUTION:At high speed mold closing, a second on-off valve 41 is opened so as to feed pressure oil to a chamber A. As a result, a first on-off valve 25 is opened, resulting in shifting zero-pressure oil in a chamber E, a chamber B and a charge tank 19 through an oil channel 33 and a communicating channel 22. At high-powered mold clamping, the second on-off valve is closed and the chamber B is pressurized and the on-off valve 25 blocks the communicating channel 22. At high speed mold opening, the second on-off valve is opened and pressure oil is fed to a chamber C. As a result, a chamber F is pressurized through the chamber C, resulting in retreating the on-off valve 25 and shifting the oil in the chamber E, the chamber B and the charge tank 19. Thus, the charge tank 19 and the chamber E in the mold clamping cylinder do not be pressurized for driving, resulting in facilitating the structure to pressure.

Title: Solenoid
Inventor: HIRATA ICHIRO
IPC: H01F7/16
Filed: 1994-09-14
Abstract: PURPOSE: To improve the responsiveness of a movable member and reduce the pulsation of a mating mounting valve to be controlled by providing a fluid control member to control the flow of fluid from a flow path opposedly to an opening part of the flow path which is provided in the movable member. CONSTITUTION: A current is applied to a solenoid main body 2 so as to attract a plunger 3 magnetically to a center post 4. Also a fluid control member 13 is mounted on the plunger 3, and a fluid control part 13B is arranged opposedly to an opening part of a flow path 12. In the reciprocating movement of the plunger 3, a flow of the fluid flowing through a clearance between the plunger 3 and an upper plate 10 from the flow path 12 is obstructed, thus producing a resistance during the movement of the plunger 3. By this, the responsiveness of the plunger 3 in A and B directions when the solenoid is turned on and off can be delayed. Then the fine vibration of the plunger 3 generated when a dither current is applied to a control current can be suppressed so as to reduce the pulsation of a mating valve.

Title: Heat sink for semiconductor and manufacture thereof
Inventor: YAMADA SUSUMU
IPC: H01L23/36
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To improve heat dissipation by increasing planarity of the bottom surface of a recessed portion, which is a semiconductor mounting portion, as compared with a conventional one. SOLUTION: This hest sink 10 for semiconductor is composed of a laminate of a plurality of metallic thin plates 20, 30. Punched out portions 21 punched in the thickness direction are formed in one metallic thin plate 20 thereof. Therefore, a recessed portion 40 for mounting a semiconductor is formed by an inner side surface of the punched portion 21 and a flat surface of the metallic thin plate 30 exposed in a state of being surrounded by this inner side surface. Consequently, since the flat surface of the metallic thin plate 30, having small surface roughness becomes a bonding surface brought into contact with the semiconductor, a contact area between the flat surface and semiconductor can be made larger than in conventional cases, and heat dissipation is improved.

Abstract: PURPOSE:To expedite the response in starting, by rectifying the AC voltage on the secondary side of a transformer with a diode, detecting a part of the voltage across a circuit to prevent the noise with a resistance and a capacitor and monitoring how the output of a power device is operated. CONSTITUTION:The current from a DC power source 1 is turned on and off with a switching transistor 3, of which the voltage is raised with a transformer 2, and is rectified with a diode 9, smoothed with a choke coil 15 and a capacitor 16 and carried to a load 17. The output voltage is taken out of the contact A of a resistance 6 with a capacitor 7 of which a snubber circuit is composed.

Title: Heat treated steel member
Inventor: HANAKAWA KATSUNORI
IPC: C22C38/04
Filed: 1990-09-17
Abstract: PURPOSE:To provide a steel member having high coefficient of linear expansion while securing rigidity by regulating the composition of the steel member to be austempered by specifying and increasing C content and Si content. CONSTITUTION:This heat treated steel member is produced by regulating C content and Si content in the steel member to 0.7-1.2wt.% and 1.5-2.5wt.%, respectively, performing austempering treatment to form the structure into a mixed structure of 30-60vol.% retained austenite and bainite, and regulating the coefficient of linear expansion to >=15X10<-6>/ deg.C. The coefficient of linear expansion cannot be increased to >=15X10<-6>/ deg.C when the amount of retained austenite is lower than the lower limit, and strength becomes insufficient when it exceeds the upper limit. When C content is less than the lower limit, hardenability becomes insufficient and the application of this member to large- sized parts is made difficult and also retained austenite becomes unstable, and, when it exceeds the upper limit, the problem of the precipitation of free carbon is taken place. Further, carbide precipitation inhibiting power becomes insufficient when Si content is less than the lower limit, and, when it exceeds the upper limit, the precipitation of free carbon is facilitated and also carbide precipitation is inhibited, and retained austenite stabilizing effects can be saturated.
