Title: Detection method for detector and servo control system
Inventor: HIRAI EIICHI
IPC: G01P3/46
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy and responsibility of entire servo system through detecting operation at a high speed with less ripple by dividing s detection signal carried by a high-frequency carrier into a plurality of signals and shifting the phase of the respective divided signals. SOLUTION: A detector for a detection signal 1 carried with a well-known high-frequency carrier divides an a.c. voltage signal of the carrier frequency W into n signals, and the respective divided voltage signals are subjected to phase shift by a phase shifter 3. The well-known frequency is delayed successively by phase shift quantity of ωt, ωt+(2π/n), ωt+(2×2π/n), ωt+(3×2π/n),... ωt+((n-1)×2π/n). The obtained n signals are squared respectively, and all the squared signals 4 are added, and the result 5 shows an output signal 6. Thus, the detection circuit is adopted so as to attain high accuracy without making the frequency of carrier to be low and to obtain a low-ripple signal without making the frequency to be high.

Inventor: KURITA HIDEMI
IPC: B03B5/28
Filed: 1989-03-20
Abstract: PURPOSE:To classify particles in sample liquid in a short time through extremely easy operation by centrifuging a centrifugal settling pipe horizontally and vertically. CONSTITUTION:A rectangular plate type collecting plate 12 is set in a free insertion and extraction state on one internal surface of the centrifugal settling pipe 10 which is formed in the shape of a rectangularly sectioned tube body which has an opening at the upper part. Then pipes 10 wherein a sample solution is charged are set in cells 26 so that the collecting plates 15 are positioned on the outermost peripheral sides when a disk 20 is rotated; when the disk 20 is rotated by a driving part 24 while the cells 26 are free about the disk 20, the tubes 10 rotates in a horizontal state because of a centrifugal force, so that large particles and small particles are distributed on sides close to the bottom and the opening respectively. Then the cell 26 are locked after the pipes 10 are centrifuged in the horizontal state for a specific time, and then the pipes are centrifuged while held at perpendicular positions. Consequently, particles in the sample are settled and stick on the collecting plate 12 while classified by the size and distributed, so the sample is classified effectively.

IPC: H01Q21/06
Filed: 1983-04-20
Abstract: PURPOSE:To remove bad influence of mutual coupling between elemental antennas by arranging metallic chips close to the elemental antennas constituting an array antenna so that the mutual coupling between the elemental antennas is cancelled. CONSTITUTION:Electric power directly coupled from circular horn antennas 1a, 1c to a circular horn antenna 1b through a courses A1, A2 is so-called mutual coupling. A part of the electric power radiated from the circular horns 1a, 1c are reflected by the metallic chips 6a-6c and enters into the circular horn antenna 1b through courses B1-B4. A part of the radiated electric power of the circular horn antenna 1b itself is also reflected by the metallic chip 6b and returned to the circular horn antenna 1b. Adjustment of a position of the metallic chips 6a-6c makes it possible to form the relation of reversed phases between a signal directly coupled through the courses A1, A2 and a signal cupled through the courses B1-B5 and cancel the mutual coupling.

Title: Antenna using r-kr lens
Inventor: MIKUNI YOSHIHIKO
IPC: H01Q19/06
Filed: 1982-04-27
Abstract: PURPOSE:To prevent reflection due to mismatching, by using two lenses of printed board constitution. CONSTITUTION:Inputted electromagnetic waves from an antenna element 21 pass through a circulator 31 and is divided into two by a coupler 61. The waves divided into two pass through R-kR lenses 51, 52 respectively and added by a coupler 60 and received by a receiver 40. Since the two R-kR lenses 51, 52 are used and they are coupled and fed through couplers 61, 61, the antenna system is symmetrical in the construction, allowing to form a multi-beam in all directions. Since reflecting waves are canceled with each other, the back lobe is reduced.

Title: Process of in-mold coat
Inventor: TSUKATANI MASATSUGU
IPC: B29C43/20
Filed: 1990-03-22
Abstract: PURPOSE:To reduce man-hour remarkably and to improve the quality of coat, while the coat is formed on both surfaces of a resin molded object by injecting coating compound into a mold at two separated times before curing and after curing of the resin material in the mold. CONSTITUTION:Molds 1, 2 are preheated at about 150 deg.C, and after a SMC sheet 5 has been set, the molds are clamped. The SMC sheet 5 is softened by heating and becomes flowing state in fitting the sheet to the shape of the mold. In this state, a first coating-injection is carried out. The injection of the coating is achieved by moving upward the rod 3b of an injector 3 and by opening an injection hole 2a. The coating 9 is fed at sufficiently larger pressure than the pressure of the mold, and penetrates the uncured SMC sheet adjacent to the injection hole 2a, and then disperses between SMC sheet 5 and the mold 1 of core side. Next, hot medium is fed into the path of hot medium. When the SMC sheet 5 adjacent to the injection hole 2a is cured until sufficient strength is objected, a second coating-injection is carried out. Since the SMC sheet has been cured, the coating 9 does not penetrate the SMC sheet 5 and permeates between the mold 2 of cavity side and the SMC sheet 5.

Title: Method for visual inspection and device for visual inspection

IPC: H01L21/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To conduct accurate visual inspection of an object of inspection, by preventing the inspection result from reflecting an effect of vibration. SOLUTION: An image of an object of inspection is picked up via an objective lens 5 by a pick-up means while an X table 2a makes main travel in the X direction. A result of picking-up is image-processed and compared with previously stored referential image data, whereby appearance inspection is conducted. After the main travel is completed, the X table 2a and a Y table 2b are caused to make sub-travel in the Y direction by the distance equating to one line. The main travel and the sub-travel are repeated, and the appearance of the object of inspection is inspected from line to line.  If a vibration exceeding a reference value is detected by a vibration detecting means 7 during main travel, at that point of time, the appearance inspection for a line under inspection is stopped, the X table turns back to make main travel again along the same line without making sub-travel when it has made main travel as far as the verge of an inspection area while image pick-up and image processing are conducted, and, if any vibration exceeding the reference value is not detected during that period, the visual inspection is conducted.
