Title: Paper discharging device
Inventor: SUEOKA HIDEKI
IPC: B41J13/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent a paper sheet from being caught in between rollers by mounting a paper sweeping rotating body to a paper discharge roller shaft through a one-way clutch, and mounting a paper discharge roller to the paper discharge roller shaft through the one-way clutch. SOLUTION: A paper discharge roller 5 is mounted to a paper discharge roller shaft 1, and a pressure roller 3 is mounted to a pressure roller shaft 4. Since the paper discharge roller 5 and the pressure roller 3 are respectively rotated in the rotating direction A of a paper sheet to be discharged, the paper sheet held by these rollers is discharged as before on a paper tray. Further, a paper sweeping rotating body 2 expands and contracts to abut against a paper sheet to catch the rear end of the paper sheet discharged between the teeth of its gear, and to sweep away it in the direction of discharging paper.  On the other hand, when the paper discharge roller 5 and the pressure roller 3 are rotated in the opposite rotating direction B to the direction of paper discharging after the completion of paper discharging, the paper sweeping rotating body 2 is not rotated due to the existence of a one-way clutch 6. Thus, the discharged paper sheet can be prevented from being caught in between the paper discharge roller 5 and the pressure roller 3.

Title: Synthesizing and distributing device for laser beam
Inventor: SUZUKI ERIKO
IPC: G02B6/28
Filed: 1986-10-09
Abstract: PURPOSE:To synthesize and distribute uniformly plural laser beams without generating the loss of laser beams by radiating 2<n> laser beams having different wavelengths, dividing each beam into two components, synthesizing these divided components, and successively dividing and synthesizing the respective synthesized beams. CONSTITUTION:The titled device is provided with plural radiating means for radiating 2<n> (n is an integer >=2) laser beams 11a-11d having respectively different wavelengths and dividing/synthesizing means for dividing these beams 11a-11b respectively into two components and then synthesizing two divided components. The dividing/synthesizing means are constituted of the number of steps for forming synthesized beams consisting of 1/2<n> components of respective beams. Thereby, the number of beams to be synthesized coincides with the number of synthesized beams and the wavelengths of all the beams can be synthesized after beam synthesis. Consequently, beam losses due to transmission or reflection can be reduced and the synthesis and distribution of beams can be uniformly performed.

Title: Micro-actuator
Inventor: KURISUTOFUAA SHII BETEII
IPC: F16K31/64
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To effectively use thermal energy by defining an insulating cell for sealing in gas and insulating thermal energy generated in an upper substrate when a sheet substrate is attached to a support. SOLUTION: When a current is supplied to the nickel layer 19 of an upper substrate 15 to heat it, a leg part 20 is bent like an arch because of a difference in thermal expansion between silicon and nickel, and a boss 18 is lifted from a sheet substrate 12. When the boss 18 is separated from the sheet substrate 12, a flow channel 11A and peripheral areas 24 and 26 are communicated with each other for the flow of fluids by a flow via 14. Then, the areas 24 and 26 form a flow passage with a device, and the flow of fluids between devices is adjusted by a valve 10A. When the valve 10A is fixed to a support 11, a volume filled with air or nitrogen is enclosed by an insulating cell 34 to function as a heat insulator.  By the existence of this insulating cell 34, the thermal capacity of the sheet substrate 12 is reduced, and thermal resistance is increased between the sheet substrate 12 and the support 11.

Filed: 1983-12-19
Abstract: PURPOSE:To eliminate a short circuit between patterns and to improve the reliability of an electronic device by putting each lead leg of the parts of an integration circuit on a wiring pattern on a flexible sheet via a conductive adhesive and then putting an insulated film over these lead legs with pressure. CONSTITUTION:A flexible sheet 7 containing an electronic circuit is stored into a case to form a miniature electronic device.

Each leg 10a of the parts 10 is set on a lead connection part 9a of a wiring pattern 9 coated on the sheet 7 via a sheet type adhesive 21 mixed with orientated fiber conductors 20. Then an insulated film 23 is put over all legs 10a of the circuit parts and the pressure is applied by means of a mold. Thus the adhesive 21 is excluded from the areas among legs 10a and patterns 9. This prevents a short circuit between the patterns 9 and therefore improves the reliability of the electronic device.

Filed: 1984-11-15
Abstract: PURPOSE:To enable the breaking capability of a semiconductor switch maximum reducing the stray inductance of the main circuit wiring in a snubber circuit with a simple stuck construction by using the external container of a condenser as an electrode. CONSTITUTION:The ends of terminal rods 1, 1 are connected to electrodes 2, 2 provided at both the ends of a condenser element 3 and one terminal rod 1 is insulated with an insulating material 15 from an external container (a conductor) 4 and is externally projected. The other terminal rod 1 is attached to the internal surface of the container and uses the container as an electrode. A terminal 16 is integrally installed on the external surface of the container. Since the terminal 16 provided on the external container of a condenser can be connected directly to the terminal 17 of a G.T.O. thyristor 5, wiring with a wire is unnecessary. The wiring from a rectifying diode 6 to a condenser 7 is also sufficient with a sort lead wire 18.

Abstract: PURPOSE:To reduce leakage currents, and to simplify a manufacturing process by forming electrodes in regions in which each p-n junction of p-type and N-type semiconductor films shaped onto a substrate is not formed. CONSTITUTION:CdS paste is applied onto a barium boro-silicate glass substrate 1 functioning as an acceptor impurity to CdS, and dried and baked to shape a CdS film 2 as an n-type semiconductor.

CdTe paste is applied with the exception of the electrode forming region for the CdS film 2, and dried and baked. Carbon paste to which an acceptor impurity is added is applied onto the CdTe paste, and a carbon film 4 is Shaped through heat treatment. A CdTe film is changed into a P-type semiconductor at that time. Electrodes 5, 6 are formed. Accordingly, leakage currents by the diffusion of the metallic electrodes can be reduced.
