Title: Method and apparatus for backup of electric signal
Inventor: FURANSESUKO KAROBORANTE
IPC: H03F3/50
Filed: 1993-03-01
Abstract: PURPOSE: To provide a buffer circuit between a high output impedance circuit and a low input impedance load by which an output voltage is kept equal to an input voltage substantially even when a load or an input condition is fluctuated. CONSTITUTION: An emitter follower stage 11 consisting of two NPN transistors(TRs) 20, 24 is connected between a VCC 18 and an output node 26 and connects to ground via a load 28. Furthermore, a 2nd emitter follower stage 13 consisting of two PNP TRs 16, 14 is connected between the VCC 18 and ground. An input to a base of the TR 14 is given to the Tr 24 via a line 27 and amplified. Simultaneously a base-emitter voltage of the TR 20 is fed to a base-emitter junction of the PNP TR 16 with a line 19 and a current is forcibly produced to a 2nd emitter follower stage 13. Thus, a voltage at an output node 26 is kept to be a prescribed relation with respect to an input voltage signal 12.

Title: Antenna
Inventor: ORIBUAA POORU RAISUTEN
IPC: H01Q1/38
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To improve the reception performance of a circularly polarized wave signal by the antenna. SOLUTION: The antenna used for a frequency of 200MHz or over has a cylindrical ceramic core 12 with a specific dielectric constant of at least 5 and pairs of spiral antenna elements 10A-10D. Each antenna element extends from a supply position at one end of the core 12 and a rim 20U of a conductive sleeve 20 adjacent to the other end of the core 12. The sleeve 20 acts like a trap insulating a ground current flowing to the antenna elements 10A-10D. In order to differentiate the length of the antenna elements, the rim 20U of the sleeve passes through the position shifted from a plane at a right angle to the axis of the core and draws a zigzag path. The antenna elements 10A-10D form simple spirals having nearly balanced radiation resistance.

Filed: 1994-02-15
Abstract: PURPOSE:To prevent forgery or alteration by constituting printing parts in such a manner that these parts emit light exclusive of the lower part or the peripheries of printed images or the peripheries of the printed images. CONSTITUTION:The surface of a paper base material 1 is provided with a thermosensitive color developing agent 2 and powder toner layers 3 are formed according to printing patterns thereon. The toner layers 3 rapidly absorb heat rays and are melt fixed and simultaneously, the lower part of the toner layers 3 and the thermosensitive color developing agents in the peripheral part react to develop colors and form the color developed parts 4 when the entire surface of the paper for copying is uniformly irradiated and heated with a light source, such as xenon lamp, having many IR rays. On the other hand, the paper surface of the parts where are no toner layers reflect the heat rays and since the temp. rise in these parts is low, the color development does not arise and non-color developed layers 5 are formed. The thermosensitive color developing agent layers 2 are formed at least in part or the whole of the printed parts. These printed parts develop the colors exclusive of the lower parts or the peripheries of the printed images and the peripheries of the printed images of the printed parts. A fluorescent agent is incorporated into the thermosensitive color developing agent.

Title: Dry-etching method and device
Inventor: KUDO YASUKI
IPC: H01L21/3065
Filed: 1992-02-27
Abstract: PURPOSE:To protect a device against damage caused by the electrostatic charge of an insulation substrate by a method wherein ionized gas is blown against an etched substrate when a high frequency power is stopped. CONSTITUTION:Nitrogen gas ionized by an ionizer 16 is blown against a substrate 10 from an ionized gas nozzle 17 provided adjacent to a cathode 12 before a high frequency power is stopped after an etching process is finished. After ionized gas is introduced, a high frequency power is stopped. Then, charge stored in the cathode 12 of a capacitor 14 flows into the substrate 10 and canceled by ionized gas, whereby the substrate 10 is turned null in electrostatic charge. By this setup, a thin film semiconductor device formed on a substrate can be protected against damage caused by electrostatic charge, so that a thin film transistor or a photosensor used for a liquid crystal display can be manufactured on a glass board of large area high in yield.
