Title: Production of optical recording body
Inventor: TSUNASHIMA KENJI
IPC: G11B7/26
Filed: 1985-10-22
Abstract: PURPOSE:To produce a recording medium having no surface defects and uneven recording by forming a laminated B/A/B film consisting of thermoplastic polymers A and B, stripping one layer B and sticking the layer A and optical recording layer to each other. CONSTITUTION:The thermoplastic polymer A and the polymer B having 0.5-5 absolute value of the difference in the compatibility parameter (SP value) with the polymer A are laminated by a co-extrusion method to form the three-layered B/A/B film. One layer B of the laminated film is stripped to expose the layer A. The optical recording layer formed on the base material and the layer A are stuck to each other. The other layer B is thereafter stripped. Since the cover layer B is stripped just prior to the use according to the above-mentioned production for process, the sticking of dust, flaws and fingerprints to the protective layer A is obviated and the optical recording body exhibits excellent optical recording characteristics.

Filed: 1993-09-22
Abstract: PURPOSE:To reduce noise in the high density recording region of a magnetic recording medium using an NiP plated Al alloy substrate textured in the circumferential direction. CONSTITUTION:A discontinuous underlayer of Cu, Al, Ge or Ag is formed on an NiP plated Al alloy substrate textured in the almost circumferential direction and an intermediate layer of a Cr alloy and a magnetic layer o a Co a oy are successively formed on t.he underlayer while impressing bias voltage.

Title: Vacuum sucker and air ejector control valve for vacuum sucker
Inventor: SAITO TAKASHI
IPC: B25J15/06
Filed: 1992-07-22
Abstract: PURPOSE:To provide energy saving by opening a flow resistor outlet, when a negative pressure in a sucker pad is a preset value or less, to increase the negative pressure by feeding pressure air to an ejector, and closing the flow resistor outlet to prevent a riseup of the negative pressure when it becomes the preset value or more, in a vacuum sucker used in an automatic assembly process. CONSTITUTION:The first opening/closing valve 3 is opened by opening an operating control valve 2, to apply pressure air to a primary side of the third opening/closing valve 8 from a pressure air source 1. Simultaneously, partly the pressure air flows out through a flow resistor 7 and the second opening/closing valve 9. Then, the third opening/closing valve 8 is opened by a primary side pressure, to generate a negative pressure by supplying the pressure air to an ejector 4. By this negative pressure, a sucker pad 6 generates a negative pressure through a check valve 10 and a filter 5, to suck an article. When the negative pressure becomes a preset pressure or more, the second opening/closing valve 9 is closed by this negative pressure, to block an outlet of the flow resistor 7, and the third opening/closing valve 8 is closed. Accordingly supply of the pressure air to the ejector 4 is stopped, and generation of the negative pressure is stopped.

Title: Fixing method of carriage in printer
Inventor: TERASAWA KUNIZUMI
IPC: B41J29/54
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To realize the reduction of noise at the start of the use of a printer. SOLUTION: In this ink jet printer 100, a carriage 2 is temporarily fixed to a housing 3 with a fixing tape 10. One end part of the fixing tape 10 is exposed beyond a cover case 5. Since the carriage 2 is temporarily fixed to the housing 3, a locking mechanism 4 can be prevented from being broken by the vibration during the transportation of the printer. Further, since the fixing tape 10 exposes itself beyond the cover case 5, the exposed part of the tape catches the eyes of a user. As a result, the user can remove the fixing tape 10 from the carriage 2 and the housing 3 before the use of the ink jet printer 100, resulting in allowing to reduce the noise at the start of the use of the ink jet printer 100.

Title: Flyback transformer
Inventor: YAMAGUCHI MUNEHARU
IPC: H01F38/42
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To effectively prevent an insulating resin from leaking to the outside of an insulation case by forming a space between the top end of the outer marginal edge of a high voltage variable resistor and bottom face of a fitting groove. SOLUTION: A gas S is left at the top end of an outer end edge 9 not at the bottom of a fitting groove 8. This prevents an insulative resin G from leaking to outside of an insulation case 4 through the gap S, except after it fills a space 11 sectioned by a partition wall 15. And this assembly structure takes much time to fill the space 11 with the resin G and the resin cures completely before filling the space. Thus, this effectively prevents the resin from leaking out from the case 4.

Abstract: PROBLEM TO BE SOLVED: To provide a laser beam machine and its method capable of detecting a machining position always with high precision and capable of machining at a desired position with high positioning accuracy and also at high speed. SOLUTION: Presence/absence of a read part is detected based on a change in an electrostatic capacity between a detecting sensor 51 fixed on a nozzle 12a for emitting a laser beam from the tip and a work 1. On the basis of this detection signal, a trigger signal TP1 is generated to which a prescribed delay time T4 is imparted by a trigger unit 24, and also a trigger signal TP2 is generated synchronized with the rise of the trigger signal TP1 by a laser controller 26, with a laser beam generated based on this trigger signal TP2 . In addition, an error detection signal, which is due to a plasma state generating at the time of laser beam irradiation, is removed by a masking signal in a gate circuit 24A.

Title: Liquid crystal display device
Inventor: MOTAI TOMONOBU
IPC: G02F1/1343
Filed: 1992-09-04
Abstract: PURPOSE:To obtain the liquid crystal display device with high display quality by reducing its display irregularity by making the quantity of deviation in the pixel potential at a display part substantially equal at least in the wiring direction of gate electric conductors or the wiring direction of signal electric conductors. CONSTITUTION:A circuit is added between the gate signal supply part of the active matrix type liquid crystal display device and the connection part of a driver IC 4. As a result of the addition of this circuit, a driving waveform which has a time constant within a range of 50 >= (time constant of trailing edge/time constant of leading edge >= 2 is obtained as a switch driving signal. This gate driving waveform is inputted and then there is no influence when a signal is written in a liquid crystal capacitance 2 and an auxiliary capacitance 3 to suppress the quantity of deviation in pixel potential which is caused when a switch is released. The deviation quantity is reducible effectively, specially, near by a driver IC which is large in the deviation quantity of the pixel potential, so it can be made substantially equal in the wiring direction of the gate electric conductors.
