IPC: B22F3/10
Filed: 1984-09-27
Abstract: PURPOSE:To obtain sintered soft magnetic iron-silicon parts having excellent magnetic characteristics by subjecting a green compact or sintered body to an oxidation treatment than to a reduction treatment and removing thoroughly carbon which is an impurity by a simple method. CONSTITUTION:The green compact or sintered body consisting of an iron-silicon blank material is subjected to the oxidation treatment by oxidation in the atm. or steam treatment to form carbon oxide in the carbon contained in the iron- component in the material. Said body is then subjected to the reduction treatment to scatter the carbon of the carbon oxide as gas which is then removed. The sintered body is thereafter magnetically annealed. The reduction treatment stage may be executed commonly with the annealing stage or the magnetic annealing stage. The residual quantity of the carbon is decreased and the sintered soft magnetic iron -silicon parts having the excellent magnetic characteristics are obtd. by the above-mentioned method.

Title: Electric-discharge lamp
Inventor: WATABE KEIJI
IPC: H01J61/36
Filed: 1981-12-16
Abstract: PURPOSE:To realize a high vapor pressure of a metal halide within an emission tube, and realize a higher luminous efficiency and a high color-rendering performance by providing each sealing body with a current-introducing member which is made of at least one compound chosen from among the carbides of titanium, zirconium, niobium, hafnium and tantalum. CONSTITUTION:For instance, current-introducing members 5 and 5' are made of a titanium-carbide bar. Titanium carbide has a thermal expansion coefficient of 7.8X10<-6>-8.65X10<-6>, which is almost the same as those of an alumina tube 2 and alumina sealing bodies 3 and 3', and a low electric resistance of 84X 10<-6>OMEGA. cm. Therefore, no cracks are generated in the members 5 and 5' due to the adjusted expansion coefficient of the members 5 and 5', and the members 5 and 5' are electrically sufficiently connected to electrodes 4 and 4' due to the small electric resistance of the members 5 and 5'. An emission tube 1 is charged with proper amounts of a rare gas, mercury and a metal halide. The above emission tube 1, usually, is used after being installed inside an outer tube one end of which is provided with a base.

Filed: 1983-10-28
Abstract: PURPOSE:To shorten the time of recording by providing a place where thermal head is separated from a drum when recording is stopped and a place where a recording paper cassette is detachable at near the drum. CONSTITUTION:When a fan-shaped gear 39 is turned in the direction of F by a drive gear 40, an arm 37 is turned by a spring 38, and a slide lever 41 is moved along a shaft 42 to open a holder 22. A thermal head 31 is moved to a position away from the drum 23, and a coupling lever 51 is released from the opening 52 of the cassette 50 against the spring 53. The cassette 50 can be freely detached. When the tip of a picture receiving paper 20 is positioned at the notch 45 of the drum 31, a drive gear 40 is reversely turned, the holder 22 is closed, the thermal head 31 is moved to a position close to the drum 23, and the coupling lever 51 is coupled to the opening 52. The gear 40 is continuously turned reversely, and the thermal head 31 is pressingly contacted with the drum 23. The moving distance of the head can thus be shortened.

Title: Semiconductor integrated circuit and its manufacture method
Inventor: YAMADA HIROYUKI
IPC: H01L27/088
Filed: 1993-07-23
Abstract: PURPOSE:To simultaneously form a gate oxide film at low withstand voltage and high withstand voltage MOS transistor with a similar thinness by preventing the impurity for adjusting Vth from being added to the surface part of the offset part at the drain side of the high withstand MOS transistor drain. CONSTITUTION:Impurities 10a and 10b for adjusting Vth of high and low withstand voltage MOS transistors are added to the surface part of a semiconductor substrate 1 at a channel (below a gate electrode 5) but are added to a part which is deeper than sources 7a and 7b and drains 8a and 8b at a part out of the gate electrode 5. Therefore, no impurity 10a for adjusting Vth is added to an offset part 9 of the high withstand voltage MOS transistor, thus preventing the characteristics of the high withstand voltage MOS transistor from deteriorating due to the impurity 10a for adjusting Vth and hence making common a gate oxide film thickness 4 of each MOS transistor gate.

Title: Still picture reproducing system in information reproducing device
Inventor: YASUKAWA KENICHIRO
IPC: H04N5/76
Filed: 1986-08-29
Abstract: PURPOSE:To perform the reproduction of a still picture without wasting an actuator, etc., by stopping only the reading operation of disk information, and continuing the readout operation of memory information, when the termination of information reproduction is commanded. CONSTITUTION:When a termination command which terminates a playing operation, or a take-out command which ejects a disk 2, is issued, a processor performs the switching control of a change-over switch 30, and controls so that a video signal passing a RAM33 from the change-over switch 30 is selectively outputted, and is derived to a video output terminal 42. In such a manner, it is possible to obtain a reproduced image even when no information can be obtained from the disk 2, because the video signal of one field written in the RAM33 is derived to the video output terminal 42. Also, in such a case, since the rewrite of the stored contents of all of the addresses in the RAM33 is performed in a state that video information obtained from the disk 2 is not supplied to the RAM 33, by operating a clear key, the stored content of the RAM33 is erased, and the reproduced image can be squelched.
