Title: Ink cartridge
Inventor: JIYON BII AARU DAN
IPC: A61P25/06
Filed: 1990-07-18
Abstract: PURPOSE: To prevent the air and an ink from reversely flowing to an ink reservoir by constituting by an intermediate member disposed between first and second conduits, and a spherical ink flow controller having a smaller diameter than that of the second conduit. CONSTITUTION: A control unit 40 has a second conduit 48 for constituting a first ink passage 49 having a diameter D1 , and the passage 49 communicates with a second ink passage 56. A spherical flow control member of a ball 80 is disposed in the passage 49. The ball 80 has a smaller diameter D2 than that D1 of the passage 49. Regarding the passage 56, the diameter D2 of the ball 80 is smaller than a width W1 but larger than a height H1 of the passage 56. The ball 80 maintains a freely floating state in the passage 49. When a negative pressure in an ink reservoir 47 invades the air into a cartridge, the ink is exhausted reversely from a supplying/printing apparatus. As a result, the ink and the air start to move reversely toward the reservoir 47. When this occurs, the ball 80 is moved in a direction of a central part 62 and toward interior by the ink.

IPC: H01L21/306
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a product with less damage in a step of peeling, by forming a semiconductor thin film on a porous layer by a normal method, and forming the porous layer by anodizing the semiconductor wafer while rotating it as a step before peeling the semiconductor thin film from the semiconductor wafer. SOLUTION: A gear 10 is provided on the outer periphery of a wafer holder 4, and the wafer holder 4 rotates by engaging with the gear provided on a driving shaft 9. A space partitioned by an opposing electrode holder 5 and the wafer holder 4 is filled with a formation liquid 3, and the formation liquid 3 are also kept in contact with the rear surface of the wafer 1 through an opening 11 of the wafer holder 4. By energizing between opposing electrodes 2a and 2b, the wafer 1 is subjected to anodizing. Hydrogen bubble generated on the rear surface of the wafer 1 is discharged from a vent 8. Although bubble generated on the surface of the wafer travels upward along the surface of the wafer, since the wafer 1 rotates during anodization, streak-like anodization unevenness due to the hydrogen bubble is not generated.

Title: Torque control type rotary electric machine
Inventor: NAKAMURA MITSURU
IPC: H02P29/00
Filed: 1988-08-01
Abstract: PURPOSE:To permit the reduction of an oscillating torque surely and quickly, by a method wherein the amount of control, necessary for making the oscillating torque zero, is operated from rotary accelerations in respective rotating angular positions during one turn of a main rotary shaft. CONSTITUTION:A rotating speed omegaR is fluctuated in accordance with a remaining difference TM-TG= Tr between the electromagnetic torque TM of an electromotive element and the load torque TG of a compressor. The time interval of a rotating pulse signal, obtained by sampling the rotating angular position phiR of a rotor based on the rotating speed omegaR, is obtained while the speed NF of rotation and the acceleration N'F of the rotation are obtained from the time interval. The speed NF and the acceleration N'F of the rotation, thus obtained, are compared with a commanding speed NC and a commanding acceleration N'C to obtain  N and  N'. A torque control system effects proportional and integral operation with respect to respective amounts of difference and determines a current command (ic) so as to nullify respective differences.

Title: Dipole antenna
Inventor: TAKAHASHI AKIRA
IPC: H01Q9/16
Filed: 1988-08-01
Abstract: PURPOSE:To obtain a low impedance characteristic at the V-shaped opening and to suppress the retrogressing wave from the termination by arranging plural branch conductors extended to the outside of the V-shape and decreased toward the V-shape opening to the V-shape conductor of the V dipole antenna whose total length is nearly 1 wavelength in parallel. CONSTITUTION:The length ls of branch conductors 12a, 12b in a feeding section 10 of the dipole antenna is selected to be ls=lambda0/2 (lambda0 is a wavelength) to obtain a high impedance. Then the length of the branch conductors arranged at an equal interval toward the antenna termination is decreased as 12a>12b>12c...12 b>12d... to attain a low impedance. Thus the retrogressing wave from the antenna termination is suppressed and the dipole antenna is made small in size with stable gain characteristic over a broad band without losing the input impedance.

Title: Welding method for sintered forged part
Inventor: ADACHI KAORU
IPC: B23K9/23
Filed: 1988-07-29
Abstract: PURPOSE:To prevent a defect like a blowhole, etc., from arising by removing oxygen contained in a sintered forged part through deoxidizing element. CONSTITUTION:In a welding wherein at least one side of a welded part is composed of a sintered forged part, the oxygen contained in the sintered forged part is removed by deoxidizer like Si, etc. For example, a pipe 2 made of refined material ST51KM is welded to a flange 1 made by a sintered forged part containing deoxidizer in a part 1b only. Or, the pipe 2 is welded to a flange 1a made by a sintered forged part containing no deoxidizer through a sintered seat 3 containing deoxidizer. At this welding time, the oxygen in a molten sintered forged part reacts with deoxidizer and the reaction product is discharged as slag on the surface of molten metal. Consequently, when the molten metal is solidified, it is deoxidized fully and blowholes are prevented from arising in the weld part.

Filed: 1993-07-06
Abstract: PURPOSE:To improve the stacking property of a recording medium, and to prevent the generation of paper feeding failure such as oblique feeding and jam by providing a curving means for curving a recording medium in a paper feeding tray. CONSTITUTION:A groove 2a as a curving means is provided at a nearly central part in the cross section of a recording medium to be set in a paper feeding tray and in the upper part of the paper feeding tray 2. In the case of recording with the paper feeding tray 2, when a recording medium is set, the recording medium enters the groove 2a to generate a recessed curve. With this curve, the recording medium has strength in the longitudinal direction and the cross direction thereof. The recording medium having the strength maintains the shape thereof by itself, and the recording medium are heaped up at the central part by the groove 2a to improve the stacking property. Consequently, a supporting guide 3 can be set at an appropriate position in response to any kind of recording medium. Since the groove 2a is provided in the upper part of the paper feeding tray 2, a curve is generated in the upper part of the recording medium, but the lower part of the recording medium is maintained flat.

Filed: 1988-08-02
Abstract: PURPOSE:To prevent the turbulence of a picture by latching a synchronizing signal storage address inside a memory and executing a reading start from the storage address in synchronizing to an internal synchronizing signal when the synchronizing signal of a method output is made discontinuous and, thereafter, returned. CONSTITUTION:When a video disk player is ordinarily reproduced, a switch 17 is controlled so as to select a terminal (a) side, and a switch 18 is controlled so as to be turned off. Consequently, a digital video signal from a memory 14 is conducted through the switch 17 to a D/A converter 19, analog-converted and conducted out to a terminal 20. When a player is selected in a rapid traverse mode for a high-speed search, the switch 17 is made to select a terminal (b) side. Then, a signal at the terminal (b) side is level-restricted by a pedestal limiter 16, and it is made into a signal in which a synchronizing signal part is removed. At such a time, the switch 18 is controlled to be turned on, the internal composite synchronizing signal of an internal composite synchronizing signal generator 23 is superimposed on the signal conducted out from the switch 17, and the stable signal can be obtained.
