Title: Non-reciprocal circuit element
Inventor: ONO NORIHIKO
IPC: H01P1/383
Filed: 1995-01-09
Abstract: PURPOSE: To attain excellent characteristics without sacrificing an insulating property by straightly extending plural wide strip conductors and extending each land in a direction different from the extending direction of its own strip conductor so as to swerve other strip conductors. CONSTITUTION: For instance, six strip conductors 12 are extended from a ground electrode 13 and a land 12 for regulating a through hole 18 for electrically connecting both faces of a double sided printed board 11 is extended from the tip of each conductor 12. Each of the conductors 12 has wide width and straightly extended. The land 12a is extended in a direction different from the extending direction of its own strip conductor 12 so as to swerve other conductors 12 on a virtual straight line on which its own conductor 12 is extended. An interval between each land 12a and another conductor 2 most close to the land 12 itself is set up to the same size. Consequently wide width of respective strip conductors 12 can be held while holding the insulating property of the conductors 12 at a high level.

Filed: 1981-01-08
Abstract: PURPOSE: To prevent the errors in measurement of distance between the leading end of an electrode and base metals by adding a zero adjusting circuit to a conventional device and making the control of the projecting length of the electrode from a torch possible.  
     CONSTITUTION: When a relay is turned on prior to operation, Ry 2  changes over from the output signal line side of a torch position detector 1 to a zero adjusting circuit 11 side, and the E volt of a DC power source E is collated with the 0 volt of a distance setting command, by which a variable DC power source 8 is outputted to lower a torch position. With the leading end of an electrode held in contact with base metals 2, a variable resistor VR of a biasing circuit 14 is regulated to regulate the feedback signal voltage for detecting the torch position in such a way as to attain 0 volt. When the relay is turned off after the end of the zero adjustment, ordinary welding operation is started. During the operation, the arc voltage is monitored with an arc voltage monitor 15, whereby the secular change of the shape of the leading end of the electrode is detected and the index for changing the position setting of the torch 1 is obtained.

Title: Stacking type transformer
Inventor: MATSUOKA TOSHIYUKI
IPC: H01F27/06
Filed: 1989-01-10
Abstract: PURPOSE:To prevent vibration of a unit transformer from being transmitted to an installation surface part and minimize deviation of the unit transformer at the upper stage when a horizontal force is operated on the unit transformer by installing the unit transformer at the lower stage to an installation surface part through a vibration-proof device and by installing the unit transformer at the upper stage to the upper part of this lower-stage unit transformer through the vibration-proof device. CONSTITUTION:Since a unit transformer 21 at the lower stage and a unit transformer 31 at the upper stage are fixed to an installation surface 26 through vibration-proof robbers 27 and 25, transmission of noise and vibration to a room below which is in contact with the installation surface part 26 can be prevented. Also, since the unit transformer 31 is mounted to the unit transformer 21 at the lower stage through vibration-proof rubbers 36 and 37, the secondary mode vibration phenomenon resulting in maximum deviation of the coupling part occurs even if horizontal force due to an earthquake etc., may operate on these unit transformers 21 and 31. Thus, deviation of the upper edge part of the upper-stage unit transformer 31 can be minimized.

Abstract: PURPOSE:To enable to obtain a high quality semiconductor device by a method wherein, after dusts deposited on the substrate after washing are removed by washing again, the coating onto the substrate is performed. CONSTITUTION:The substrate 1 previously cleaned and preserved is mounted on an adsorption end provided on a motor rotary shaft 21 and adsorbed via an adsorption pipe 31. Next, the substrate 1 is rotated in the direction of the arrow A in this state, simultaneously an ultrasonic oscillation mechanism 4 is operated, and, while simultaneously giving a rotation and oscillation to the substrate 1, dusts deposited on the substrate 1 are washed off by the water injection from a water injection pipe 5. Then, the ultrasonic oscillation is stopped, and the substrate 1 is sufficiently dried. While successively rotating the motor 2, a resist is sprayed in an inertia gas atmosphere resulting in the formation of a fixed film. Thus, a washing effect can be enhanced by the simultaneous employment of sonic oscillation and substrate washing caused by a water injection.

Abstract: PURPOSE: To prevent a secondary air supply check valve from degrading the durability due to heat by connecting a branch line with a secondary air supply passage, which includes an exhaust gas release check valve and is communicated with an exhaust pipe through a duct.  
     CONSTITUTION: A branch pipe 8 is connected with a seondary air supply passage 6, which includes an exhaust gas relief check valve 12 and is communicated with an exhaust pipe 14 through a duct 13. When exhaust pulse pressure is negative, open  air passes through an air cleaner 11, a seondary air supply check valve 10, and the secondary air supply passage 6 and comes into an exhaust port 3, where unburnt composition in exhaust gas is promoted to oxidize. Under high load and at high velocity, exhaust gas reflux straightly flows through the secondary air supply passage 6 into the branch pipe 8 and is accmulated in a gas reservoir 15, not flowing to the secondary air supply check valve 10. The secondary air supply check valve 10 may be therefore prevented from decreasing in durability due to exhaust gas heat.

Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of texture staining when two-component developers are used and to prevent the adhesion of carriers to the surface part of a photosensitive drum. SOLUTION: This development bias control system consists in providing the rear stage of an electrostatic charger with a surface potential sensor 26 for detecting the surface potential of the surface of an image carrying member 4 in such a manner that this sensor exists in the image part and controlling the development biasing voltage to be impressed on a developing device 7 in accordance with the surface potential detected from the surface potential sensor. In this system, the development biasing voltage is impressed on the developing device at the time the part of the image carrying member 4 electrostatically charged by the electrostatic charger arrives at the developing position.  The development biasing voltage is kept continuously controlled so as to attain a prescribed potential difference from the surface potential of the part of the image carrying member 4 in the non-image part detected by the surface potential sensor 26 when the part of the image carrying member 4 of the non-image part arrives at the developing device. The development biasing voltage is impressed on the image part so as to attain the prescribed potential difference on the basis of the surface potential just before the part of the image carrying member 4 of the image part arrives at the developing position.
