Title: Power supply device for magnetron
Inventor: MATSUMOTO TAKAHIRO
IPC: H05B6/66
Filed: 1988-04-20
Abstract: PURPOSE:To enhance the efficiency and suppress the cost by forming the secondary winding of a high voltage transformer in divided windings, and furnishing a space to be formed against the core. CONSTITUTION:A high voltage transformer 6 is equipped with a primary winding 25 in connection with inverter circuit 33 and a secondary winding 28 to supply high-voltage and high frequency power to a magnetron 15, wherein the secondary winding 28 is formed in divided windings with a space 30 provided between the winding and the core of transformer. That is, the high voltage transformer 6 can be constructed in small size by making the power supply with high frequency by the mentioned inverter circuit 33, which together with divided wind of the secondary winding 28 of the transformer, lessens the inter- line capacity of the winding to allow wasteful current not to flow easily between the windings, which should reduce heat emission from the winding. Further, provision of the space 30 generates an air stream to increase the cooling effect of the transformer windings and the whole construction.

Title: Deflection yoke
Inventor: IDE MASASHI
IPC: H01J29/76
Filed: 1989-04-17
Abstract: PURPOSE:To make a form of beam spots in the periphery of an image plane to come close to a circle and improve resolution by flowing the vertical deflecting current full-wave-rectified to a pair of compensating coils provided in parts closer to an electron gun side than an area on which a magnetic field caused by a vertical deflecting coil works. CONSTITUTION:A compensating coil 8 and a compensating coil 9 are respectively fixed in side surfaces of a cylindrical part 6 facing to each other. When the sawtooth direct current from a vertical deflecting current source is fed to terminals 15a and 15b, the current flowing to the compensating coils 8, 9 are rectified to full-wave rectified wave form by rectifying diodes D1-D4. Magnetic fields such as a magnetic field F and a magnetic field 9 passing in reverse direction to each other in the upper and the lower of an electron beam B are generated, and a sectional form of the electron beam B is deformed from a form showed with a broken line to a form showed with a continuous line by these magnetic fields. Namely, the electron beam B is deformed so as to be crushed in the vertical direction. Consequently, beam spots in the upper end and the lower end of a fluorescent surface are corrected to a form close to a circle.

Abstract: PURPOSE:To realize a miniature structure as well as a small scale of a system for a titled distributor and at the same time to ensure the even distribution of light, by unifying an optical branching function and an optical distributing function. CONSTITUTION:A dielectric multifilm filter 18 which reflects only the light of a specific wavelength lambda1 and permits the transmission of ther wavelength light is formed on a concave surface 17 of a convex/concave lens 12 that functions as a convex lens as a whole.

Title: Device and method for reading image and recording medium
Inventor: TERAJIMA HISAO
IPC: H04N1/04
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To match the resolutions of respective colors and to improve the color reproducibility of black horizontal thin lines and dot originals even in the case of adjusting light source dispersion at the time of moving and reading by turning on/off a light source within one storage period of an image sensor and setting the ratio of the on-time and off-time of the light for the respective colors. SOLUTION: At the time of receiving line synchronizing signals SYNC, a CUP 103 starts interruption processing and writes a value to registers 126 and 128 through a system bus 107 and an internal bus 124 within a interruption routine. That is, light source color designated signals to be applied from the next synchronizing signal SYNC and the duty signals of a PWM 127 are reserved in the respective registers 126 and 128. In such a manner, by changing the light emitting color and on/off duty of a light source in synchronism with the synchronizing signals SYNC, the light source is controlled. That is, one light source is uniformly turned on/off during one line synchronizing period relating to any light source of R, G and B and the ratio of the on-and-off time of the light is made different in the respective colors.

Title: Mig welding method by hollow welding wire
Inventor: OKADA TOSHIHIKO
IPC: B23K9/24
Filed: 1978-08-16
Abstract: PURPOSE: To well stabilize arc in MIG welding by letting shielding gas flow out from a hollow welding wire.  
     CONSTITUTION: When sheilding gas 8 such as helium gas is flowed out from the hollow part of a hollow welding wire 6, an arc flame 9 concentrates at melt zone 11 and gouge out molten metal, thereby increasing the depth of penetration of weld zone. In addition, the potential in the central part of the arc is increased. When the shielding gas 7 such as Argon is flowed out from a nozzle 2, the surroundings of the arm flame 9 are perfectly shielded and the inclusion of air becomes difficult to occur. At this time, the shielding gases 7 and 8 vary in specific gravity and therefore they are difficult to mix with each other, thus high effect is obtainable with a small rate of gas flow.
