Title: Manufacture of thermionic emission type cathode
Inventor: SHIBATA CHIYOUKICHIROU
IPC: H01J9/04
Filed: 1980-01-17
Abstract: PURPOSE:To prevent the arcing and the mode jamp of a magnetron and to improve the service life by additionally providing a process for coating a protective film of material corresponding with the metal of cathode substrate in accordance with the usage onto the cathode surface. CONSTITUTION:A cathode 1 immersed with an electron emission material is assembled with a cathode tube 2 and inserted into a jig 3 to expose the cathode 1 and connected to the positive electrode 4. A target 6 such as WO3 is held on the other electrode 5, then high frequency voltage is applied from a power source 8 under inert ambience such as Ar 7. When applying the high frequency high voltage from such equipment, the Ar gas is ionized to positive ion having high energy and enters into the negative side of the electrode or WO3 face which receives high energy and emit itself to be adhered to the surface of the cathode 1. Consequently it can be adhered effectively on an emission material as a protective film resulting in considerable lengthening of the magnetron.

Title: Method and device for adding gray level to multi-gray level halftone image
Inventor: RICHARD W VANCE
IPC: H04N1/41
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To provide an output of an image with more apparent gray values, while a printer/copying machine minimizes a size of a print buffer. SOLUTION: A dither matrix is tiled sequentially and logically on an image, and a relation between a gray value of each pixel and a dither matrix value overlapped logically is discriminated. Each of the relation values at each odd number tile position is discriminated as to whether or not which of (n-1) sets of threshold levels it exceeds and a 1st gray modulation value in excess of a median is assigned to a pixel. Discrimination is made similarly at each even number tile position. When the median is exceeded, a 2nd gray modulation value is assigned. Then a laser modulation value is checked as to the pixel, arranged corresponding to three sequential dither matrix tile positions. The gray modulation value assigned to a median pixel is smoothed, in response to the gray modulation value assigned to the adjacent pixels, and the result is applied for the control of a laser print engine.

Title: Branching device
Inventor: MIZUGUCHI KEIICHI
IPC: H03H7/46
Filed: 1981-01-13
Abstract: PURPOSE:To compensate the phase distortion of an output signal, by providing a resistance circuit to a branching transformer to reduce the standing wave ratio. CONSTITUTION:The signal a high-frequency signal source 3 is supplied to a load 5 and a load 7 via a branching transformer 8. The noise caused at the load 7 is given to the primary and secondary coils 9 and 10 of a transformer 8 from a resistance R1. In this case, the signals flowing to both coils are offset to prevent the application of the noise to the load 5. A resistance R2 between an output terminal 6 and an earth gives the matching to the impedance of the terminal 6 to reduce the output voltage-standing wave ratio. A series circuit 13 consisting of a resistance RO and a coil LO is connected between an input terminal 2 and an output terminal 4. The circuit 13 compensates the phase of the current which flows into a branching device 1 from the terminal 4. Thus the output voltage- standing wave ratio is reduced for the terminal 4.

Inventor: IWAMI SHIGEO
IPC: B29C45/40
Filed: 1982-01-14
Abstract: PURPOSE:To produce moldings of different sizes at the same time by providing an interrupter to interrupt the gate of a cavity for molding a small-size product and a driver to drive the interrupter when the pressure of resin in the cavity for molding small-size product reaches a given pressure. CONSTITUTION:Molds are made up of a large-size molding cavity 1, a small-size molding cavity 3, a runner 4, the gate 5 of the large-size molding cavity, the gate 6 of small-size molding cavity, and a slender plate-like pin 7 to interrupt the gate 6. When the small-size molding cavity 2 of the molds filled up with a molding material, the gate 6 is shut out. Thus, the molding material supplied thereafter is sent only to the large-size molding cavity 1, but not to the small- size molding cavity 2.

Title: Rush current preventer
Inventor: NANBA SUSUMU
IPC: H02H3/08
Filed: 1993-01-14
Abstract: PURPOSE:To reduce heating value by blocking rush current flowing through a rush current preventing resistor upon occurrence of instantaneous power interruption or chattering under low load and to reduce the scale of rush current preventer by reducing power of the rush current preventing resistor. CONSTITUTION:When a voltage obtained by dividing a rectified voltage Va by means of resistors P6, R7 matches the voltage at the joint of a resistor R8 and a capacitor C9, a triac 2 is turned ON to limit rush current by means of a resistor R1 upon turn ON of an AC power supply. The triac 2 is turned OFF after turn ON of AC power supply depending on the heavy and light states of a load circuit 4 at a time when the voltage divided by resistors R13, R14 at the time of instantaneous power interruption drops below a reference voltage V4 produced through a resistor R15 and a Zener diode D16. In case of an instantaneous power interruption under a state where the load is light and the rectified voltage Va is high, AC power supply is turned ON again while sustaining the triac 2 in ON state thus blocking the rush current flowing into the resistor R1.

Abstract: PURPOSE:To enhance connecting reliability by arranging a fiber layer on a terminal conductor. CONSTITUTION:When soldering is performed, a terminal conductor 2 and a printed-wiring board 7 are connected to each other by solder 8. A flux 9 contained in the solder 8 goes along the conductor 2, and enters in an insulating case 1, and tries to stick to a contact point part 6, but is absorbed in a fiber clearance of a fiber layer 3 pressed in and fixed to a peripheral part of the conductor 2, and passes through a microscopic clearance 5, and does not enter the case 1. Thereby, sticking of the flux to the contact point part 6 can be prevented. Since the layer 3 is arranged in this way, the conductor 2 is heated, and a filler such as an adhesive 4 is heated and hardened, and the microscopic clearance between the conductor 2 and the case 1 is not filled up, so that the flux 9 coming at soldering time by going along the conductor 2 can be prevented from sticking to the contact point part 6 by entering the case 1. Thereby, solderability is improved, and connecting reliablity can be improved.

Abstract: PURPOSE:To display selectively plural display parts with one light source by attaching respectively photoconductors to plural operating buttons, providing a piece of photoconductive part to face the other end of each photoconductor and providing the light source to one end of the photoconductive part. CONSTITUTION:Operating buttons 3a-3d are attached to plural operating parts 1 having switches 2, the other of which are projected when one thereof is pushed. The photoconductors 4a-4d are attached respectively thereto in such a manner that one end thereof is exposed to the surface of the operating button 3 and the other end is projected from the rear of the button 3. A piece of the photoconductive part 5 is provided to face the rear end of the photoconductors 4a- 4d. The rear end of the photoconductor 4d enters the recess 7d of the photoconductive part 5 when, for example, the button 3d is pushed to throw the switch 2 and therefore the light from the light source 8 passes through the photoconductor 4d from the part 5 and emerges to the top end of the photoconductor 4d thereby making the display. The channel display is thus executed by the photoconductors 4a-4d.
