Title: Vapor deposition device
Inventor: NODA SHOICHI
IPC: H01L21/203
Filed: 1986-02-24
Abstract: PURPOSE:To prevent the cloudiness of an observation port by the gettering action of a deposition layer on an adsorption wall in the vicinity of the observation port by attaching vapor from an evaporation source for gettering onto the adsorption wall. CONSTITUTION:Vapor is not projected directly to main evaporation sources 2a, 2b, a substrate 3, a heater 4, an observation port 5, etc. from an evaporation source 7 for gettering, and the evaporation source 7 discharges its own vapor near a space in which there is a vapor flow toward the observation port 5 from the main vapor sources 2a, 2b. A masking shield 8 limiting the direction of discharge of the vapor of the evaporation source 7 for gettering and an adsorption wall 9, on which the vapor of the evaporation source 7 is deposited and which adsorbs other vapor, are mounted onto the inner wall of a tank 1. Consequently, the single crystal of gallium arsenide is grown on the substrate 1, and the inside of the tank 1 during deposition can be observed from the observation port 5. The gallium vapor of the evaporation source 7 for gettering adheres on the adsorption wall 9 in the vicinity of the observation port 5, arsenic vapor projected to the adsorption wall 9 section is coupled, the reevaporation of the arsenic vapor is prevented, one part of the gallium vapor of the evaporation source 7 is combined with arsenic in a space, and arsenic is changed into vapor difficult to be reevaporated and attached onto the inner wall of the tank 1 up to the observation port 5.

Abstract: PURPOSE:To easily and stably obtain a bearing member having desired size and permeability, by shaving the bearing surface of a bearing member made of a metallic porous material to the desired size so as to form burrs at opened parts at the side of said bearing surface and then electrolytically exuding said burrs. CONSTITUTION:The bearing surface 8 of a bearing member 3 made of a metallic porous material is shaved to finish its inner diameter to predetermined size. Hereon, the shape and sharpness of an edged tool to be used are properly selected to facilitate the formation of burrs 7, 7 and to make the permeability of said member 3 smaller than a desired value. This member 3 is fixed to the inside of a metallic gas supply chamber 2 and dipped in a liquid electrolyte 11 inside an electrolytic cell 10, and a round bar electrode 12 is inserted into the center of the member 3 and connected through an ammeter 13 and a variable resistance 14 to the negative side of a DC power source 15. On the other hand, the chamber 12 is connected to the positive side of the power source 15, and a voltmeter 16 is provided. Hereon, by applying an electric current between the member 3 and the electrode 12, current density at the edge parts of the burrs 7 existent at the edges of the squeezed openings 17 is especially enhanced to exude said burrs. Thus, the area of the opening 17 is gradually increased. When the permeability of the member 3 reaches a desired value, the supply of electric current is stopped.

Abstract: PURPOSE:To detect a defective product in an inspector of a lead frame of a film carrier, by a method wherein laser beam is divided in two with a half mirror and one beam is made to hit a master while the other does an object to be tested to compare the two beams of light transmitted therethrough. CONSTITUTION:A laser beam 13a is radiated from a laser unit 13 and reflected with mirrors 9 and 6 to hit a conical mirror 7..A rotating shaft 4a is rotated with a motor 4 to move a moving stage 5 and then, after the motor 4 is shifted the circle size of a scanning beam is changed. Then, the beam reflected from the conical mirror 7 is divided in two with a half mirror 14. One of the beam is allowed to travel straight to hit a lead frame 3a of a master while the other is reflected to hit a lead beam 3b of an object to be tested. A signal of time during which the beam is transmitted or shielded is inputted into a processing circuit 12 with the frame 3a of the master and the frame 3b of the object being tested and a lead width and a lead interval are determined to compute a difference between the both. Thus, the determining of the lead width and interval of the body being tested facilitates the detection of defective products.

Title: Protective relay
Inventor: SHINPO YOSHIYUKI
IPC: H02H3/05
Filed: 1990-02-23
Abstract: PURPOSE:To monitor an analog input without occurrence of a monitoring fault at the time of an unbalanced load by a feeder by constructing a device of a circuit which changes over a time of detection of a CT circuit monitoring fault according to the amplitude of a load current, and a circuit which locks the CT circuit monitoring fault when a zero-phase I monitoring fault is detected. CONSTITUTION:At the time of loading of a feeder, a load current having an equal amplitude and a phase difference of 180 deg. and being equivalent to a single phase flows, and therefore a CT circuit monitor 1 detects a fault from Imax-alpha.Imin>=beta1. However, a zero-phase I monitor 3 does not detect the fault since a resultant vector turns to be zero. A load current smallness detector 2 is made to operate by a feeder load. Therefore an inhibit circuit 4 judges the feeder load to be present, and a change-over is made in an inhibit circuit 5 to a fault detection counter 7 at the time of loading of the feeder. Therefore a fault detection counter 6 is locked. Even when an unbalanced load of the feeder occurs for several minutes, accordingly, the fault detection counter 7 operates longer, and consequently no monitoring fault takes place.
