Title: Printed circuit board having magnetic coating film and electromagnetic wave shielding layer and fabrication of the same
Inventor: KAWAKAMI SHIN
IPC: H05K3/28
Filed: 1993-03-02
Abstract: PURPOSE:To prevent generation of a noise by preventing influence of magnetic field and electromagnetic wave generated in a wiring circuit of a printed circuit board. CONSTITUTION:Magnetic coating films 3, 4 are formed directly on a part or the entire part of the surface where a wiring circuit 2 is formed and the rear surface of an insulated substrate l where a conductive circuit 2 is not formed in the front and rear surfaces of the insulated substrate having formed a printed wiring circuit consisting of a conductor and moreover magnetic wave shielding layers 5, 6 are formed directing to the predetermined surface of the magnetic coating films 3, 4. The magnetic coating films 3, 4 are mainly formed of a magnetic material of high permeability with the initial permeability mu of 10<2> or more and the coercive force of Hc [Oe] of 1 or less. The magnetic material is covered with an insulator. Even when the magnetic material is exposed on the surface of magnetic coating films, it does not give any adverse effect to insulation.

Title: Plasma etching device
Inventor: SASAKI ICHIRO
IPC: H01L21/3065
Filed: 1989-03-20
Abstract: PURPOSE:To make density distribution of plasma uniform and uniformly treat a wafer having a large area by providing a means of causing an electric current generating a magnetic field to flow near the side wall of a plasma production chamber at the side wall of the plasma production chamber. CONSTITUTION:The inside of a treating chamber 3 is kept at a vacuum atmosphere under a prescribed pressure and microwaves radiating into the treating chamber 3 convert a treated gas into the state of plasma and treat a wafer 7 by produced ions and radicals. When conducting wires 8 are provided around the treating chamber 3 and a power source 9 allows d.c. current to flow, magnetic fields shown by lines 10 of magnetic force are generated. Since the magnetic fields that are generated by a current source decrease in inverse proportion to a distance from the current source, magnetic field distribution is greater in the vicinity of wall face that is close to the current source and is low in a center part. Plasma that takes place in the vicinity of a window 2 permeable to the microwaves is uniformized while conveying to the wafer 7 and uniform treatment of the wafer 7 is performed.

IPC: E02F9/14
Filed: 1988-03-18
Abstract: PURPOSE:To facilitate handling and enhance the working effectiveness by sensing the current position of a boom, and controlling automatically the motion of the boom at a speed corresponding to the difference from the target position for motion which is set in advance. CONSTITUTION:When a boom 16 is to be moved, its target position is set in advance, and a control lever 44 is operated, and now the boom 16 swings toward the target position at a speed corresponding to the amount of operation on the control lever 44. When the boom 16 approaches the target position and reaches the catch range, the motion of the boom 16 is changed over to the auto mode, and the boom 16 approaches the target position at a speed corresponding to the difference between the current position and the target position. The speed of swinging slows down gradually so as to stop at the set target position smoothly.

Title: Manufacture of semiconductor device
Inventor: ITOU HITOSHI
IPC: H01L29/417
Filed: 1984-04-03
Abstract: PURPOSE:To manufacture an asymmetrical gate, whose length is 0.5mum or less, accurately and to improve characteristics, by flattening a deep dug-in structure by a thick resin layer, providing an electric insulating layer and a thin film having charged particle-ray sensitive property thereon, thereby forming a three-layer structure. CONSTITUTION:A hole is dug in an N-GaAs layer 22 on a GaAs substrate 21 so that a thickness corresponding to the threshold voltage of a MESFET, i.e. 2mum, is made to remain from the surface. An organic resist film 23 is applied on the surface. UV light is projected on the film so as to bake the film. Thus the dug- in structure is flattened. Then an SiO2 film 24 and a PMMA resist film 25 having charged particleray sensitive property are formed and a three-layer resist structure is formed. Thereafter, gate opening parts 26 and 27 are formed. The film 23 is etched until the layer 22 is reached. An opening part 28 is overetched, and a minute pattern, from which an asymmetrical gate can be formed by a lift-off method, is formed. Then, a pattern of Al29 is formed on the surface of the groove part.

Title: Compact printer
Inventor: TANAKA TOSHIO
IPC: B41J2/32
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a compact printer capable of establishing a larger detached distance of a head with a low load, by setting different action positions of two cams acting on an up and down lever. CONSTITUTION:In printing, one end 15a of an up and down lever 15 is pressed by a cam A19, and the other end 15b acts so as to stand a thermal head 7. After printing for one line is completed in a direction B, the pressing against the end 15a by the cam A19 is cancelled. Until a head holder 6 reaches a cam B20, the lever 15 becomes rotatable about a sliding shaft A17. Therefore, the end 15a of the lever 15 rotates in a direction C about the sliding shaft A17 by the cam B20. Due to this rotation, the end 15b of the lever 15 abuts against a pin 16 of the thermal head 7, and the end 15b rotates in a direction (d) about a fulcrum 21. In this manner, the detached state of the head is realized. In addition, the rotation of the lever 15 in the direction C can be conducted with a low load.

Abstract: PURPOSE:To aim at reducing the operator's burden, by arranging a plurality of actuators having different strokes in a pitch feed station in which levers are operated, so that the actuator which has a stroke coincident with the stroke lever, alone is engaged. CONSTITUTION:An actuator 37a arranged in a position corresponding to the rollers 49 of reel units 3a, 3b vertically moves by a long stroke while an actuator 37b arranged in a position corresponding to the roller 49 of a unit 3c vertically moves by a short stroke. Then, the actuators 37a, 37b engage with only the rollers 49 of reel units which arrive at pitch feed stations for supplying component parts, and therefore, do not interfere with the pitch feed levers 29 of the adjacent reel units while the actuator 37a does not interfere with the lever 29 which is pushed by the actuator 37b. Accordingly, the units 3a through 3b may be arranged in an optional order on a table 1, and are surely applied with pressing forces having corresponding strokes, and therefore it is not necessary to pay an attention, thereby the operator's burden may be reduced.

Title: Detector for density of developer
Inventor: SHIBATA HISAO
IPC: G01N27/72
Filed: 1982-04-23
Abstract: PURPOSE:To obtain a developer density detector which detects accurately the toner density and has a simple structure and is produced inexpensively, by utilizing the variation of the fluidity of a developer due to the toner density difference of the developer. CONSTITUTION:A developer 2 agitated by an agitating roll 5 is attracted to the surface of a magnetic roll 3 in accordanced with the rotation of the magnetic roll 3 and is carried in the direction of an arrow A. The developer 2 is stuck to the surface of a photoreceptor 8 so that the thickness of the developer 2 is constant by a sticking quantity controlling part 1a, and the developer is sent to a density detector 4. The developer 2 sent to the density detector 4 is scraped from the surface of the magnetic roll 3 by a scraping part 9a of a guide member 9 and passes through a flow passage 10 and is dropped to the lower part of a case 1 again. While the developer 2 passes through the flow passage 10, the toner density is detected. When the toner density of the developer 2 passing through the flow passage 10 is low, the developer 2 is fluent because the quantity of a magnetic carrier is large, and the fluidity of the developer 2 is high, and the developer 2 does not stagnate in the flow passage 10.
