Title: Tape guide
Inventor: MASUDA SHIGERU
IPC: G11B15/60
Filed: 1994-03-31
Abstract: PURPOSE:To realize the stable running of a magnetic tape by coating a rigid carbonaceous film of Vickers hardness of 3000-5000 on surfaces of the unrotatable metallic tape guides which are arranged on the running path of the magnetic tape. CONSTITUTION:The tape guides 22, 23 which are made of stainless steel, constitute drum entrance and exit guides 5, 6. A stainless steel tape guide 16 is a fixed guide arranged between the drum exit guide 6 and a channel erase head 12. The rigid carbonaceous film 31 of Vickers hardness of 3000-5000 is coated respectively on the surfaces of these tape guides 5, 6, 16 by the vaccum deposition method, etc. In this case, the thickness (t) of this rigid carbonaceous film is approximately 1mum and the surface roughness is 0.5-0.6S. The variance in the frictional resistance of the magnetic tape caused by the repeated running of the magnetic tape is thereby remarkably reduced.

Abstract: PURPOSE:To attain the detection and reproduction of plural signals being equally recorded while the rotational frequency of a motor kept at a fixed level, by recording the signals periodically on a concentric spiral track and controlling with switching and periodically the states of connection between a pickup device and the detection/reproduction devices corresponding to those recorded signals. CONSTITUTION:Both spaces Ly and lc are proportional to the bands of luminance and color signals respectively and these signals are recorded at the inside and the outside of a spiral track with Ly and lc set at the same value, i.e., with the same density. A switch control means is provided to detect the luminance and color signals alternately by means of a single pickup device and supply both signals alternately to the luminance and color signal detection/ reproduction circuits respectively. The switch control means contains a switch means 5 and a switch control circuit 6 which detects the switch signals between spaces Ly and lc on a disk by a pickup device 1 and switches the means 5 alternately and periodically between both spaces Ly and lc.

Title: Image forming device
Inventor: SATO SHOGO
IPC: G03G15/08
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device constituted so that an excellent image can be formed by suppressing the deterioration of non-magnetic one- component developer (toner, for example) and uniformly and properly electrifying the non-magnetic one-component developer. SOLUTION: This laser printer is constituted so that the toner T being as the non-magnetic one-component developer is triboelectrified and carried to the surface of a photoreceptor drum 23 by rotating a supply roller 28 and a developing roller 27 while bringing them into contact with each other. The roller 28 is the sparse foaming roller having open cells whose number is under 30 pieces per one inch. Since large pressure force does not act on the toner T, the toner T is not deteriorated. Besides, titanium oxide and silica are mixed and added to the toner T as additive. However, since the titanium oxide is provided with almost mediate electrifying property, the toner T is uniformly and properly electrified. Besides, the flowability of the toner T is enhanced by the silica.

Abstract: PURPOSE:To easily obtain a diamond film excellent in smoothness by previously reducing an oxidative film by hydrogen plasma and removing it and thereafter performing film growth by a low pressure synthetic method when the thin diamond film is grown on a base plate to be treated which has the oxidative film. CONSTITUTION:A base plate 8 to be treated which has an oxidative film on the surface is arranged in the reaction pipe 1 of a microwave plasma CVD device. Then gaseous H2 is supplied through an introduction port 2 in such a state that an exhaust system has been actuated. The oxidative film on the base plate 8 to be treated is reduced and removed by introducing microwave through a waveguide A thereof and generating hydrogen plasma. Then reactive gas such as CH4 is introduced through an introduction port 2 and microwave is introduced through the waveguide A to generate plasma. A diamond film is grown on the base plate 8 by a low pressure synthetic method. Thereby the diamond film having smoothness close to the mirror surface is formed at about 0.42mum/hour rate of film formation.

A pair of such blocks 14 are butted to each other, and a hard solder material 21 and 22 are poured into the grooves 15 and 16 to unify these grooves. At the same time, a hard solder material 23 is poured into the groove 20 to form a nonmagnetic layer 26 having deteriorated permeability at the part 19 by the diffusion of the material 23. As a result, a winding hole 24 is formed, and at the same time a space part 25 of an equilateral triangle is formed by the groove 18. Then two joined blocks 14 are sliced to obtain a pair of cores 27, and a winding 29 is applied. Then the base part is cut, and the tip part is polished. Thus a magnetic head is finished. Thus the length of a magnetic path (shown by a solid line) is decreased with improvement of magnetic characteristics and strength for a thin film head.

Title: Method for removing smell and vapor generated in casting mold into which molten metal is poured
Inventor: TOBINAGA TAKESHI
IPC: B22D27/15
Filed: 1987-04-06
Abstract: PURPOSE:To permit efficient capturing of org. solvents and smells by subjecting a casting mold to suction by a reduced pressure to cool and condense volatile materials such as gases and vapor in the mold after casting of a molten metal and before shaking out. CONSTITUTION:The molten metal is poured from a runner into the casting mold 9 formed by solidifying molding sand with an org. resin binder to produce a casting. The temp. of the mold 9 is high and the smells and vapor of the materials generated by the solvent and resin in the resin binder and thermal cracking of the solvent remain in the mold at the time of shaking out the mold after casting. The smells and white fumes spread to a working place if the mold is shaken out in this state and, therefore, the mold is sucked by the reduced pressure to guide the smells and vapor to the outside of the mold and the smells and vapor are cooled and condensed to a liquid state in order to prevent such spreading. The mold 9 is placed on an upper plate 1a of a suction box 1 and a thermoplastic resin film 10 is put on the mold 9 from above for the above-mentioned purpose. A vacuum pump 7 is then operated to reduce the pressure in the chamber in the reduced pressure box. Then, the film 10 comes into tight contact with the mold 9 and the air flows into the holes formed to the film 10. The air carrying the smells and vapor in the mold 9 is guided through the box 1 to the outside of the mold 9.

Filed: 1987-04-08
Abstract: PURPOSE:To attain an almost complete correction with using parts at a low price by overlapping a vertical period parabola voltage for correcting the pincushion distortion of right and left with a voltage by the screen brightness of the same period.
