IPC: H02B13/065
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To perform stable detection of partial discharge by reducing the effects of external noise in an antenna device for diagnosing insulation. SOLUTION: An electrical-to-optical transducer 17 is housed in a case 13 constituting an antenna, and an electromagnetic signal received by an antenna device 11 is converted into an optical signal and transmitted to an insulation diagnosing device by an optical fiber 18. The antenna device 11 is arranged in the vicinity of the opening part of an electric apparatus and detects electromagnetic waves leaking from the inside of the container. As the antenna device 11 does not comprises metal objects except antennas (12 and 13), it is possible to prevent variations in antenna characteristics by metal objects, the entry of external noise, etc.

Title: Mounting of electronic component and apparatus therefor
Inventor: TANEDA KOKI
IPC: H05K13/02
Filed: 1989-06-22
Abstract: PURPOSE:To simplify the structure of an apparatus and to shorten a mounting tact (processing cycle) time by mounting a chip component at a position directly removed from a tape on a printed board as it is. CONSTITUTION:A cover tape 9 and a bottom tape 10 adhered to a carrier tape 8 are simultaneously peeled, and a suction nozzle 60 is moved down to a position directly above the tape 8 through a hole 80 of an upper guide for guiding the tape 8 to a position where the tape 8 is fed at one pitch. According ly, a chip component in the component hole of the tape 8 can be immediately sucked. Then, the component can be moved down while it remains sucked to the nozzle 60 through the hole 81 of a lower guide for guiding the tape 8, thereby specifying the position of the chip to the nozzle 60. Further, the nozzle 60 protrudes downward to mount the component at a predetermined position on a lower printed board 300. Thus, since a chip component supply unit is not moved, the structure of a facility can be simplified, and a mounting tact time can be largely shortened.

Title: Electrostatic recording body
Inventor: NEMOTO SUSUMU
IPC: G03G5/10
Filed: 1986-07-08
Abstract: PURPOSE:To form an image having a practicably satisfactory density in low to high humidity environment by subjecting a conductive base to a conducting treatment by a polypyrrole. CONSTITUTION:The conductive base is subjected to the conducting treatment by the polypyrrole. The formation of a low resistance layer consisting of the polypyrrole is executed by putting the base to which a catalyst is transferred and the pyrrole into a hermetically sealable vessel, substituting the air therein with gaseous nitrogen, maintaining the temp. in the system at 40-70 deg.C, sealing the vessel hermetically, allowing the same to cool down to 20 deg.C and holding the same for 10-30min. The direct impregnation of the liquid pyrrole to the base and the hermetic sealing thereof are an equally good alternative in the case of paper having the catalyst. The specific surface resistance of the base varies largely with reaction conditions such as the amt. of the oxidation catalyst, polymn. time, polymn. temp., kind of binders, and the amt. of monomers and binders. The base is so formulated as to have 5X10<5>-5.0X10<8>OMEGA, more adequately 5X10<6>-5X10<7>OMEGA specific surface resistance. A recording layer is provided on such polypyrrole layer.

Title: Sense amplifier
Inventor: OBATA HIROYUKI
IPC: G11C7/06
Filed: 1988-06-27
Abstract: PURPOSE:To simplify the circuit constitution and to change the output signal of a sense amplifier with the full amplitude between the earth potential and the supply voltage by forming the sense amplifier by eight pieces MOSFETs and two piece inverters. CONSTITUTION:The current (cell I) flowing to a turned-on memory cell flows to an FET N1 biased by the output of an inverter IN 1. The current (cell I) flows to an DET P2 also. Consequently, the current (cell I) flows to an FET P3 in the saturation area. A current does not flow to an FET N5 biased by the output of the inverter IN 2 because the memory cell is turned off. A current does not flow to an FET P6 similarly. Consequently, a current does not flow to FETs P7, N8, and N4. Therefore, VCC is outputted from a connection point 2. When memory cells are turned on and off oppositely, earth voltage 0V is outputted from the connection point 2.

Title: Multi-slit light projector

IPC: G02B27/42
Filed: 1990-06-19
Abstract: PURPOSE:To improve the resolution of three-dimensional measurement by moving constitution which includes at least either of a 1st and a 2nd diffraction gratings by an actuator by a fine distance about a light source. CONSTITUTION:The light source is provided with the actuator 6 which moves the constitution including at least either of the 1st and 2nd diffraction gratings by the fine distance at right angles to parallel slit light. When the actuator 6 moves the 1st and 2nd diffraction gratings 2 and 3, a cylindrical lens 4, and a shutter array 5 in an (x)-axial direction crossing the (y)-axial slit light by, for example, a half as large as a pitch P, the parallel slit light 9 becomes equivalent to slit light whose pitch is a half as large as the pitch P, so that the picture element resolution can be improved. Similarity, when the constitution is moved divisionally by 1/3 and 2/3 time as large as the pitch P, the parallel slit light 9 becomes equivalent to slit light whose pitch is 1/3 as large as the pitch P. Consequently, the three-dimensional measurement accuracy of a body to be measured can be improved by the simple constitution.

Thus, the communication cycle is quickened to cause the delay in a timing signal to be eliminated, and when not in copying, the data is set in the transmission buffer to apply transmission of data including the sequence data. Then all kinds of data communication are attained and the system copes with exchange of lots of information and the efficient communication suitable for the property of each data (such as status and timing) is attained.
