Abstract: PROBLEM TO BE SOLVED: To provide a device for generating uniform and high density plasma by installing a metal rod of a coaxial conversion antenna projecting into a chamber by burying in a dielectric window in the bottom of a wave guide, and installing a reflecting mirror for reflecting microwaves in the position separated from the tip of the metal rod buried in the dielectric window. SOLUTION: A glass substrate 7 for a liquid crystal on which a resist pattern is formed on the surface is placed on a holder 8 within a treating room 6 of a chamber 1. Gas within the chamber 1 is exhausted with a vacuum pump to the outside of the chamber 1 through gas exhausting pipes 10 to keep the inside in nearly vacuum. After exhaust, treating gas such as mixed gas of oxygen gas and carbon tetrafluoride is supplied to a plasma forming room 5 in the upper part of the chamber 1 through a gas supply pipe 9. At a point of time when the inside of the chamber 1 becomes specified pressure by the treating gas, a microwave is introduced into a wave guide 3. Plasma is generated in the plasma forming room 5 of the chamber 1.

Title: Infrared ray communication equipment
Inventor: SUGITO YOJI
IPC: H04B10/07
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To enable communication by irreducible minimum emitted light quantity by determining the emitted light quantity for infrared ray communication in the communication with a communicating party. SOLUTION: The output of a serial controller 3 is connected with a modulation circuit 5 and the output of a modulation circuit 5 is connected with the base of a transistor 6 for switch. In the case of a data transmission, the serial controller 3 outputs the data instructed from a control part 1 as preliminarily set serial data to the modulation circuit 5. After the transmission data from the control part 1 is modulated to reduce the influence of noise by the modulation circuit 5, a transistor 6 for switch is turned on/off in accordance with data information. As a result, when the transistor 6 for switch is turned on, current flows in an LED 9, the LED 9 emits light, and when the transistor is turned off, the LED does not emit light. Therefore, current flowing in the LED 9 can be made irreducible minimum for communication.

Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of optical waveguide to manufacture easily an optical waveguide capable of keeping a high optical propagation characteristic irrespective of the kinds of supporting base substances. SOLUTION: A dummy layer having a pattern in which a solution, in such as a grating shape can infiltrate sufficiently up to a central part, is formed on a transparent substrate 11, and an optical waveguide 16 is formed thereon. Then, the transparent substrate 11 is immersed into an acidic solution. The dummy layer is dissolved to be removed, an area in which the dummy layer has been formed becomes a gap 17, and a clad layer 13 is brought into a condition contacting with one portion of the substrate 11.

Further, physical force F is appied to the transparent substrate 11 to separate the substrate 11 from the optical waveguide 16. The waveguide 16 is thereby transferred to the wiring board 18. Since the waveguide 16 contacts partially with the transparent substrate 11, the substrate 11 is separated easily.

Title: Cut and feed control in nc machine
Inventor: KUMEI HIDEO
IPC: B23B1/00
Filed: 1992-08-05
Abstract: PURPOSE:To prevent sawtooth shape wear with feed pitch intervals from producing at a tool tip by not specifying the feed pitch of the tool tip at a constant, but varying it within a specified range for each cut cycle. CONSTITUTION:When a specified portion of a work B is cut by an NC machine, a feed pitch (p) of a tool tip A is not specified at a constant, but varied within a specified range for each cutting cycle. The lower limit of this variable width is a limit that an extension of cutting time caused by reducing the feed pitch (p) is allowed in feed pitch variation, and the upper limit of it is a limit that a surface roughness caused by increasing the feed pitch (p) is allowed in feed pitch variation. Thus sawtooth shape wear with feed pitch intervals can be prevented from producing at the tool tip A.

Title: Input circuit for semiconductor integrated circuit
Inventor: SUMI KATSUAKI
IPC: H01L27/082
Filed: 1984-10-05
Abstract: PURPOSE:To reduce the emitter parasitic capacitance of emitter follower transistors Trs by forming the N-P-N type emitter follower Tr having a conduction type reverse to the N-P-N type emitter follower Tr in an input circuit for an IC between said Tr and a constant current source. CONSTITUTION:When an input signal source 2 is magnified, capacitance 104 between a collector and a base in a Tr10 functions as parasitic capacitance for the Tr10 because the base 100 in the Tr10 is grounded in an AC manner, and a transistor Tr3 must be charged. However, the Tr3 is charged sufficiently rapidly because it has emitter follower constitution. When the input signal source 2 is reduced, capacitance 104 between the collector and the base in the Tr10 corresponds to capacitance 104 between a base and an emitter in a Tr4 because the Tr10 is operated while a collector region and an emitter region thereof are reverse to those of a normal Tr. Capacitance between a collector and a substrate generally extends over not less than quintuple as much as capacitance between the base and the emitter at that time, thus reducing a discharge time to approximately one fifth of a conventional example when the same current value as the conventional example is flowed. Accordingly, the quick speed of response is obtained.
