IPC: C08J7/04
Filed: 1981-08-18
Abstract: PURPOSE:To form a plating layer having excellent adhesion on the surface of a molding, by etching a polyacetal resin molding and then plating the molding by immersion in an ammoniacal nickel chemical plating bath. CONSTITUTION:A polyacetal resin molding is degreased, dried and subjected to an etching treatment by immersion in a sulfuric acid-phosphoric acid mixture containing an acid-resistant surfactant. The treated molding is water-washed and subjected to a sensitizing and activating treatment as usual and then immersed  in an ammoniacal nickel chemical plating bath to form a plating layer on the  surface of the molding. For example, said plating bath contains NiSO4 (20g/l),  sodium hypophosphite (15g/l), ammonium citrate (25g/l), ammonia water and sulfuric acid (pH adjusting), and lead nitrate (trace). EFFECT:There is no need of neutralization and hot-water washing after the etching treatment. It is possible to form a plating layer having a peel strength of 900-1,400g/cm.

Title: Method and device for exposing photoresist by electron beam
Inventor: AANORUDO REISUMAN
IPC: H01J37/317
Filed: 1985-06-14
Abstract: A method and apparatus are disclosed for exposing photoresist using an incident electron beam during the fabrication of a semiconductor device. The method includes the steps of coating the substrate (50) with a photoresist (51) that is exposed in response to an electron beam (52). The electron beam is projected onto the photoresist (51) and deflected to trace a pattern. The voltage and the amount of charge of the electron beam are controlled as it is deflected so that the energy incident upon the coated photoresist is correlated to variations in the photoresist thickness to expose photoresist with minimal penetration therethrough to underlying structures.

Title: Optical recording apparatus
Inventor: TOKUMARU HARUKI
IPC: G11B7/0045
Filed: 1992-05-21
Abstract: PURPOSE:To obtain a stable recording operation by a method wherein a laser-driving current is controlled by utilizing the driving signal of, and positional information on, a relay lens for focusing use and a change in recording power on the face of a recording medium due to the displacement of the relay lens for focusing control use is suppressed. CONSTITUTION:A beam of recording-face reflected light from an optical recording medium 9 is passed through a light path in the reverse direction; it is reflected by a splitter 3; it is guided to a reproducing optical system 10; a servo signal for a focusing tracking operation is detected and a recorded signal is reproduced. When the displacement of a focusing relay lens 5 is zero, the aperture diameter of an object lens 8 is nearly equal to the light flux of a beam of object-lens incident light 11. The beam of lens incident light which displaces the lens 5 to the direction of the lens 8 by means of an actuator 6 is converged; its spot diameter becomes large; a beam of radiant light becomes large. When it is displaced to the reverse direction, the spot diameter is narrowed and the power is reduced. When it is displaced further, its diameter is increased again due to its aberration. The position of the focusing relay lens is detected; after that, the driving current of an LD is controlled in such a way that the arrival rate of LD radiant power on the recording medium in its position is not changed largely. Thereby, a stable recording operation is performed.

Filed: 1989-05-23
Abstract: PURPOSE:To get conductive film with high stability by laminating a sensitive resist layer which is alkali-developable on a conductive film laminate and a sensitive laminate having a temporary support which is transparent and peelable. CONSTITUTION:An under coat of vinylidene chloride resin, etc., is laid in a thickness of 0.05-10mum on a support made up of polyethylene terephthalate, etc. Then, a compound semiconductor of cuprous iodine or silver iodide dissolves into a solution at 0.1-50wt.% together with resin precursor to be applied to that under coat. The content of the compound semiconductor in that coated layer is set as 100-1000mg/m<2> to form a transparent conductive layer. An alkali- developable sensitive resist layer is formed in a thickness of 1-60mum on a conductive film laminate thus formed, and a sensitive laminate having a transparent and peelable temporary support of polyesters such as polyethylene terephthalate is laminated on that sensitive resist layer. Thereby, the crystalization of the compound semiconductor due to aging can be controlled, so that the transparent and conductivity are stabilized for a long time and a conductive film whose adhesion to the upper layer is good, whose stability is high can be made.

Title: Protection of stationary type scherbius device
Inventor: ICHIKAWA HIROAKI
IPC: H02P23/00
Filed: 1980-09-19
Abstract: PURPOSE:To prevent commutation failures at the time of power restoration by the use of a simple circuit, by connecting a thyristor switch which is turned on at the power restoration after an AC power supply has instantaneously failed and a mechanical switch in series with said thyristor switch, between the terminals on the DC side of a forward converter. CONSTITUTION:The secondary power of an induction motor 1 is converted into DC by a rectifier 2; then, the power is fed back to the power supply via a transformer 4 under the control of the gates of a thyristor device 3. A thyristor 10 is provided between the terminals on the DC side of the rectifier 2. The thyristor 10 is turned on when the power is restored after the AC power supply has instantaneously failed, thereby the application of the excessive voltage on the thyristor device 3 is prevented by shorting the DC circuit. A mechanical switch 11 is provided in series with the thyristor 10. The switch 11 is opened after the power restoration, the current of the rectifier 2 is flowed to the converter 3, thereby the normal operation is performed. Therefore, commutation failures and the detects of the thyristors can be prevented without fail in the very simple circuit.

Title: Drive shaft having excellent fatigue characteristic
Inventor: YAMANAKA JUNJI
IPC: F16F15/32
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent the fatigue strength reduction of an attaching part and to set this device within a short time by fixing the balance weight to a drive shaft with a band. SOLUTION: After a balance weight is disposed in a specified position on a drive shaft, this is fastened by winding a band on the drive shaft and fixed by a fastening force. A band fastening mechanism may use, for instance if a wire is used, a method of twisting up both ends of the wire or a method of using a commercially available hose band, and thus a method is optionally selected. Since welding which causes a fatigue strength reduction is not used for fixing, fatigue fracture from the attaching part is prevented and fixing work is completed within a short time. Further, by providing an elastic body having Young's modulus of 300N/mm<2> between the balance weight or the band and the drive shaft, a fatigue characteristic is improved.
