CONSTITUTION:A cross polarized wave signal 16 is branched into two, one of them is given to circuits 18, 19 generating an upwards convex and a downwards convex frequency characteristic, a variable attenuator 20 and a variable phase shifter 21 to obtain a signal having the same frequency characteristic as the cross polarized wave signal leaked to the main polarized wave signal 15 and having the identical level and opposite phase. The signal and the said cross polarized wave signal are added by the circuit 22 so as to cancel the interference component. The circuit 18 varies respectively the sharpness and resonance frequency of the resonance circuit by changing the value of a variable resistor 28 and the capacitance of a variable capacitor 30 in the circuit 18.

Title: Reference generating apparatus for dust inspection apparatus
Inventor: TAKAHASHI HISASHI
IPC: H01L21/66
Filed: 1990-03-30
Abstract: PURPOSE:To easily generate a reference of wanted dust inspection apparatus by monitoring the number of ground beads to be sprayed to a semiconductor substrate, controlling quantity of air to a constant amount and always controlling movement of the semiconductor substrate to a constant value. CONSTITUTION:A mixed solution of round beads and solvent obtained on the basis of experience is prepared within a vessel 3. A semiconductor substrate 4 is set on a semiconductor substrate supporting base 5. The round beads flowing out from the vessel 3 with flow of air by setting of a three-way valve 7 is counted by a dust counter 8. A reduction valve 1 is adjusted and a mixing ratio in the vessel 3 is changed so that the desired amount can be obtained. When the desired amount is obtained, the round beads is discharged toward a semiconductor substrate 4 from a discharging port 2 by setting the three-way valve 7. Since distance between the discharging port 2 and semiconductor substrate 4 is always kept constant, the speed of X-Y stage is always controlled to become constant. Thereby, a constant amount of beads can always be sprayed to the semiconductor substrate.

Title: Method for continuity test of contact hole in semiconductor device
Inventor: FURUKAWA MAKOTO
IPC: H01L21/66
Filed: 1990-03-30
Abstract: PURPOSE:To facilitate solution of defectives and to improve yield by coating contact holes with a conductive material before irradiation with electron beams and by observing secondary electrons emitted from the irradiation to check continuity. CONSTITUTION:Contact holes serving as the connection points of an element 2 (diffusion layer) on a semiconductor substrate 1 with a wiring layer are bored by patterning and etching with photoresist. The next step is application of conductive photoresist 6 to form a pattern which coats contact holes. Another step is irradiation of the conductive photoresist 6 that coats contact holes with electron beams as shown by arrow marks. Irradiation with electron beams yields secondary electrons responsive to the electron beams. Through observation of these secondary electrons, variations in the potential of the conductive photoresist over contact holes, e.g. continuity of contact holes, can be checked.

Title: Continuous extruding method of wire rod and its device
Inventor: NAGAI MASAHIRO
IPC: B21C23/00
Filed: 1979-07-03
Abstract: PURPOSE:To improve the yield of wire rods by engaging the stationary shoe block and the press roll to the movable roll having the concave groove on the outside circumference, and cutting the blank which is press-contacted in a concave groove with a press roll by a cutting blade of a shoe block, and extrusion-molding the same by a die. CONSTITUTION:A movable roll 13 is rotated to feed a blank 14 to a concave groove 15. Then, the blank 14 is buried in a state of press contacting in the concave groove 15 by a press roll 17, so that it becomes a press-contact blank 19. As the movable roll 13 revolves, the material reaches the cutting blade 21 of a stationary shoe block 20 and is thereby cut. At this time, extruding pressure is generated by the shearing force of the press-contact blank 19 and the press-contact blank 19 having been cut is extruded through a die 22 and becomes a wire-like body 23.

Title: Heat exchange ventilator
Inventor: URANO MASASHI
IPC: F24F7/08
Filed: 1984-04-25
Abstract: PURPOSE:To provide a heat exchange ventilator which is excellent in sound insulation and protectivity against ingress of cool air by providing a heat exchange element for transmitting the heat of warm air to cool air between a duct used as a passage for cool air and a duct used as a passage for warm air and making both ducts flexible. CONSTITUTION:When fans 16 and 17 are rotated, outdoor air (cool air) passes through an air supply duct 13 and enters within the chamber, and, at the same time, passes through an exhaust duct 14 and air within the chamber (warmed air) is exhausted out of the house thereby to carry out indoor ventilation. Upon this occasion, a heat exchange is carried out between supply air and exhaust air by a heat exchange element 19, and the temperature of supply air becomes close to the indoor temperature, thus the room temperature change due to the ventilation and heat loss being small. At the time of cooling in summer season, fans 16 and 17 are rotated reversely, the duct 14 is used as a supply air passage (warm air passage) and the duct 13 is used as an exhaust air passage (cool air passage). Since the ducts are flexible, they are properly bent and even a long duct can be accommodated in a narrow space and long supply air and exhaust air passages can be provided whereby it is possible to reduce the quantities of noise and cool air.

Abstract: PURPOSE:To improve the dielectric strength characteristic of a tube and decrease a defect of its fluorescent screen, by preventing a reflecting film from peeling off, that is, by forming no reflecting film on the concaved part of a concaved mirror which is adapted to one end of a holding structural substance. CONSTITUTION:An aluminum reflecting film 53 evaporation deposited on concaved surfaces of a concaved mirror 5 is not deposited on its concaved surface portion adapted to a cylindrical holder 4. The maximum diameter of an area, on which the reflecting film of the concaved mirror 5 is coated, is smaller than the diameter of the circumferential edge part at one end of the cylindrical holder 4 adapted to said concaved surface. Accordingly, the reflecting film 53 is never exfoliated by being rubbed.

IPC: G01L5/10
Filed: 1984-04-26
Abstract: PURPOSE:To facilitate the replacement of a load cell while supporting a wire with a support metal against breakage of a load cell by supporting the wire on a steel tower through the load cell and the support metal movable by the specified length. CONSTITUTION:A U shaped support metal 20 is connected to insulator chain 3 for stretching wires. A load cell 11 is mounted at the center of the support metal 20 through a joint 28 and then, on a steel tower 1 with a fitting metal 12. Slots 21 and 22 are made on both sides of the support metal 20 and connected to arms 23 and 24 with pins 25 and 26 respectively. The tension of the wire is received by the insulator chain 3, the support metal 20, the joint 28, the load cell 11 and the fitting metal 12 to detect the tension thereof. But when the load cell 11 is broken, the tension works on the support metal 20 and the support metal 20 moves by the length l1 of the slots 21 and 22 from the arms 23 and 24 to support the wire. Thus, as the support metal movable by a specified length is provided, the wire can be supported safely even when the load cell is broken or replaced.

Filed: 1979-07-05
Abstract: PURPOSE:To eliminate bad influences of the shading of an optical system by using a shading correcting circuit for a facsimile equipment that converts video signals into black-and-white binary signals and sends them. CONSTITUTION:Video signals output from an image sensor are input to terminal 5. White-level extracting circuit 6 is an integral network which is charged with a time constant fast enough to follow up a maximum picture frequency and discharged with a slow time constant corresponding to the gradient of shading and from the input video signal, a white level is extracted. The output of circuit 6 is input to white-level drop stopping circuit 7 composed of a clamping circuit. Since this circuit 7 prevents accurate shading extraction from becoming impossible when the black interval of the video signal is extremely long, the input is clamped at a fixed potential equivalent to the minimum amplitude of shading. The output of circuit 7 is voltage-divided by variable resistor 9 and input as the reference potential of binary-coding circuit 11 and this reference potential and video signal 5 are compared to each other to obtain black-and-white binary signal 12 by converting.
