Title: Manufacture of shadow mask
Inventor: OTAKE YASUHISA
IPC: H01J9/14
Filed: 1992-08-27
Abstract: PURPOSE:To apply and form a resist film affecting the quality of open hole, homogeneously at a desired thickness. CONSTITUTION:A photosensitive resin liquid 6a is applied by a first coater 15a to one main surface of a metal thin plate 1, which is cleaned in the surface, and which is carried horizontally. The metal thin plate 1 is then passed through a dry furnace 16a, and a resist film 4a having an aimed thickness on one main surface of the metal thin plate 1 is thus formed. The temperature of the resist film 4a is measured by a non-contact radiation thermometer 28a at a point where the metal thin plate is drawn out of the dry furnace 16a, and feedback control is carried out for heater voltage and for a hot air heat source so that the metal thin plate is passed through and drawn out constantly within a set temperature range from 60 deg.C to 80 deg.C. The metal thin plate 1 is reversed through a turn roller 18b and is carried horizontally, and coating film of a photosensitive resin liquid 6b of aimed thickness is formed on the other main surface of the metal thin plate 1 by a second coater 15b, which is passed through a dry furnace 16b, and photosensitive resin films are thus formed on both of the surfaces.

Title: Apparatus for inspecting through-hole of printed circuit board
Inventor: ANDOU MORITOSHI
IPC: G01N21/88
Filed: 1982-12-27
Abstract: PURPOSE:To accelerate an inspection speed by dispensing with preparation for blocking a through-hole from light, by arranging a rotor cooperated with a print board in a closely contacted state to the illumination side of said printed circuit board while blocking the through-hole from light by the mutual movement of the rotor and the print board. CONSTITUTION:A plating layer 3 is formed to the inner wall of a light pervious hole 2a provided by drilling to the light pervious substrate material 2 of a print board 1 to form a through-hole 4. Light 5 from a defect inspecting light source is allowed to irradiate one surface side of the print board 1 and a roll shaped rotor 6 for blocking the through-hole 4 from light is arranged to the illumination side. The rotor 6 has a length for simultaneously blocking the through-hole 4 from light and supported in a revolvable manner by an arm 8 while a torsion spring 9 is provided to the arm 8 under tension to bring said rotor 6 into close contact with the light irradiated surface of the print board 1. A light detector 10 is arranged to the other surface side of the print board 1 so as to be opposed to the rotor 6 and, when there is a defect 3a in the through- hole 4, light incident to the substrate material 2 from the periphery of the rotor 6 is diffused in the substrate 2 to generate bright light in the through-hole to enable defect detection. By this method, an inspection speed is accelerated.

Title: Semiconductor device
Inventor: ITSUNOI KATSUAKI
IPC: H01L29/808
Filed: 1985-10-16
Abstract: PURPOSE:To improve the yield, the operating speed of the power consumption, by forming a plurality of field effect transistors having gates with different widths on one compound semiconductor substrate and by providing the transistors with different threshold voltages Vth. CONSTITUTION:A semiconductor device of this embodiment has field effect transistors (FET's) 2 and 3 formed on a substrate 1 of a compound semiconductor such as GaAs. The widths of the gates of these transistors are orientated differently: the width of the gate of the FET 2 is orientated along the direction VE according to the mesa and the width of the gate of the FET 3 is orientated along the direction DE opposite to the mesa. Thus, the structure has a cross section as shown in the figure. More particularly, an N<+> type region 15 is formed on a semi-insulating GaAs substrate 11 and an N-type semiconductor region 12 is overlaid thereon. A P<+> type region 3 is formed on the major face of the N-type semiconductor region 12 by means of the etching. A high-melting metal 14 is deposited on this P<+> type region 13 and covered with an insulation film 17. Further, an ohmic metal is deposited for providing an ohmic electrode. Thus, a gate length LG is defined by the width of the high-melting metal 14.

Title: Muting circuit
Inventor: YAMASHITA MITSUYOSHI
IPC: H03M1/08
Filed: 1982-12-27
Abstract: PURPOSE:To prevent the generation of distortions during a muting time and to improve the S/N by changing the aperture ratio of an aperture signal in response to a mute control signal which is separately supplied. CONSTITUTION:The aperture ratio is controlled by the level of a mute control signal (c), and as a result, a PAM signal (f) is delivered with no muting in a high level period of the signal (c). While the signal (f) is muted completely in a low level period of the signal (c) and not delivered. The soft muting is performed in a transition period. Thus a muting circuit is constituted just with addition of a pulse generating circuit 7 and an AND circuit 5. This circuit amplifies greatly the circuit constitution. In addition, no increment of distortions nor deterioration of S/N is never caused since no analog signal system is operated.

Abstract: PURPOSE:To easily perform high-accuracy matching by moving an image pickup device corresponding to image data and setting image pickup magnification, and making a negative plate image of another color placed on a layout form coincident with an image projected on a monitor. CONSTITUTION:Image data of respective film negative plate of a master plate are obtained and their image pickup position and image pickup magnification are recorded. Then the image data are projected on the monitoring television 31 and the image pickup device 24 is moved to a corresponding image pickup position and also set to the image pickup magnification. At this time, film negative plates 37 and 38 of other colors are arranged on the layout form 35 and the images projected on the monitor television 31 are made coincident with each other. Consequently, cyan plates 37 and 38, a yellow plate, etc., can easily be positioned for the master plate with high accuracy only by monitoring the monitor television 31.

Title: Organic matter treatment apparatus
Inventor: KIMURA NORIAKI
IPC: B09B3/00
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To eliminate unpleasantness due to malodor emitted out of undecomposed organic matter at the time of exchanging carriers by installing a stirring body to stir stored matter in a treatment tank in which carriers and organic matter are stored and giving the alarm at the time when a load detection means to detect the load of the stirring body detects the load at a prescribed value or higher at the time of stirring.

Title: Test device of corona of power cable
Inventor: TAKADA MITSURU
IPC: G01R31/12
Filed: 1982-12-28
Abstract: PURPOSE:To attain a defect detecting capability of a degree similar to said capability of the AC corona test, by charging a cable to be tested with a DC voltage and discharging the cable to be tested through an inductance which constitutes a closed loop together with the cable to be tested and applying a damping oscillation wave voltage to detect corona discharge. CONSTITUTION:A cable 13 to be tested is charged to a prescribed potential or higher by a DC voltage attained by rectification in a rectifier 11, and a high voltage switch 14 is closed. Since the electric charge stored in the cable 13 to be tested is discharged through an inductance 16, the resonance phenomenon is generated, and the damping oscillation wave voltage is applied to the cable 13 to be tested. If discharge is generated in a defective part of the cable 13 to be tested, a waveform having a corona pulse 41 due to corona discharge besides a noise pulse 40, which is generated when the high voltage switch is turned on, is observed by a corona measurer 19 to detect the presence of the defective part. The capability of detecting the defective part is in a degree similar to that of the AC corona test, because it is confirmed that corona discharge is generated in a high voltage region having a crest value M or higher in case that the damping oscillation wave voltage is applied after confirming that corona discharge is generated by a normal AC voltage having the crest value M or more.
