Patent JP-H0878529-A (JP)
Title: Method and apparatus for surface treatment, surface treatment for substrate, method for forming multilayer wiring board, and formation of orientation film for liquid crystal panel
Inventor: MORI YOSHIAKI
IPC: H01L21/28
Filed: 1995-03-31
Abstract: PURPOSE: To enhance reliability of wiring while lowering the resistance by generating gas discharge under a pressure close to atmospheric pressure, exposing a metal film deposited on the surface of a substrate to a gas active species produced through discharge and oxidizing the surface of the metal layer, thereby imparting corrosion resistance thereto. CONSTITUTION: The atmosphere between the tips of both electrodes 3 and a substrate 6, including the vicinity thereof, is substituted by a gas containing oxygen. When a predetermined voltage is applied from a power supply 2 to the electrodes 3, a gas discharge takes place between both electrodes 3 and the substrate 6. Active species, e.g. oxygen ions and excitation species, are thereby produced in the discharge region 8. Upon exposure to such active species, a metal wiring 7 is oxidized and a thin metal oxide 9 is deposited on the surface thereof. Since the surface of the metal wiring 7 is oxidized and coated with the metal oxide 9, the lower metal wiring layer has no possibility of being etched along with the upper metal wiring layer even if the interlayer insulation film is not deposited thinner than the thickness required for electric insulation and even if any pinhole is present.

Title: Printer
Inventor: NAKAYAMA HIROYUKI
IPC: B41J11/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To constantly maintain a platen gap at the time of printing of a cut paper by a printer, capable of printing both a roll paper and a cut paper. SOLUTION: In an ink jet printer 1 wherein a position for printing a roll paper 5 is formed in a part of a printing position 11 for printing a cut paper 4, a roll paper platen surface 16 for regulating the printing position with respect to the roll paper 5 is disposed receding from a cut paper platen surface 13 for regulating the printing position 13 with respect to the cut paper 4 by a size G of at least the thickness of the roll paper. In printing the cut paper, a platen cap at the part corresponding to the cut paper to be conveyed in the state superimposed on the roll paper can be flush with the other part of the platen cap not corresponding to the cut paper. Therefore, deterioration of the printing quality with respect to a cut paper derived from fluctuation of the platen gap can be eliminated.

Title: Soft card feeding device
Inventor: SHIRATORI YOZO
IPC: B65H11/00
Filed: 1993-04-23
Abstract: PURPOSE:To shorten a card carrying path and to obtain a compact and light- weight magnetic card reader by forming a branch path not to lead a card to be carried toward the card inserting port to this port between a card inserting port and a magnetic head. CONSTITUTION:A card carrying path 5 is led to a card discharging port 4 from a card inserting port 3, and a branch path 8 is formed on the path 5 at a position between the port 3 and a magnetic head 7 so that a card 1 to be carried toward the port 3 is branched out of the path 5 and not led to the port 3. Thus, the card 1 inserted through the port 3 is sent to the head 7 by a card feeder means 6. The card 1 is processed by the head 7 and returned to the port 3. In this case, the card 1 is branched out of the path 5 by the path 8 formed between the port 3 and the head 7 and, therefore, prevented from returning to the port 3. As a result, the distance between the port 3 and the head 7 is reduced and the path 5 is shortened. Thus, a compact and light- weight magnetic card reader is obtained.

Title: Ghost eliminating device
Inventor: KOBAYASHI REIICHI
IPC: H04N5/21
Filed: 1988-04-20
Abstract: PURPOSE:To improve the ghost eliminating function by inserting a differentiation circuit and a median filter to efficiently eliminate the pulse noise having a large amplitude. CONSTITUTION:A differentiation circuit 13 which differentiates an extracted reference waveform and a median filter 14 which detects and outputs a median of plural continuous fields with respect to the differentiated reference waveform are added to a tap gain generating part 1. Thus, the pulse noise having a large amplitude is efficiently eliminated to improve the ghost eliminating capacity. Since the extracted reference waveform does not pass the median filter as it is but the differentiated reference waveform passes the median filter, the median is detected with a high precision without being affected by the variance of the DC level of the reference waveform though this DC level is varied in each field.

Abstract: PROBLEM TO BE SOLVED: To maintain high plasma density, even if a processing object is diametrically enlarged by directly connecting an electrode to an electric power supply means by a conductor, without arranging a matching circuit constituting a distributed constant line and a matching box between the electrode and the electric power supply means in the matching circuit. SOLUTION: A plasma device is constituted by directly connecting an electrode 107 and an electric power supply means 101 by a conductor 105 to reduce power loss supplied to the electrode from the electric power supply means, except for a matching circuit constituting a distributed constant line and a matching box almost decided in characteristic impedance. The output of the electric power supply means 101 is connected directly to the electrode 107 via the conductor 105 so that a processing object 108 is arranged on the electrode 107. A multistage high frequency amplifier 103 uses an electric circuit constituted of plural bipolar transistors, an inductor, a capacitor and a DC power source, and the matching circuit 104 does not use a semi-fixed variable capacitor but rather uses a variable capacitor.

IPC: F16F9/10
Filed: 1988-04-21
Abstract: PURPOSE:To easily change a spring constant and the amount of expansion by transmitting rotation of a wheel of a truck to a hydraulic actuator and accumulating kinetic energy in a closed fluid storage device. CONSTITUTION:When a towering structure 1 is vibrated by wind or the like, wheels 4 of a stationary truck 3 are rotated by frictional force with rails 2 where the wheels are moved and a hydraulic motor 5 is rotated in one direction through a chain 10. Oil in a hydraulic cylinder 15 is passed through one oil path 13 and shifted to a cylinder chamber 18 of a hydraulic cylinder 16 through the other oil path 14. When the quantity of oil in the cylinder chamber 18 increases and pressure increases, a piston 20 is pushed in against the repulsive force of a coiled spring 24. At this time, the repulsive force of the spring 24 becomes resistance force, so that the rotation of a rotary shaft 6 of the motor 5 and the wheels 4 are braked to restrain vibration of the structure 1. Oil is sucked up from an auxiliary tank 27 to change pressure in the cylinder chambers 17, 18, whereby a spring constant is converted.
