Abstract: PURPOSE:To make a simple structure without using unnecessary expansion pipe by forming a sealed space on at least one part of a bed and frame and communicating this sealed space and a light conductor. CONSTITUTION:A laser beam passes through a freely expandable light conductor 5 from a laser generating device 3. The laser direction is then changed to the Y direction from the X direction by a mirror containing box 6, condensed by a beam condenser 4 to perform the working. In case of changing the work position, a frame 2 and beam condenser 4 are moved, communicated to the bed 1 having a large sealed space even in the case of the light conductor 6 being expanded and the frame 2 and the inner part pressure becomes about constant. The light conductor 6 having different diameter in multicylindrical shape is mainly used. With this mechanism, the laser beam machining can be performed with the device of a simple structure without using unnecessary expansion pipes.

Filed: 1980-11-17
Abstract: PURPOSE: To prevent a short-circuit flow from occurring at a bottom part and enable a thickened sludge to be taken out as it is, by a method wherein the bottom part of a tank is formed to be a substantially V-shaped slant bottom, a groove for containing a screw is provided at the lowermost part of the bottom, and a group of slant plates parallel to the slant bottom is provided in the tank above the bottom.  
     CONSTITUTION: Sewage treated by a flocculator to cause microflocs to grow into larger flocs is introduced into the slant plate precipitator. The flocs contained in the sewage are settled by the effects of the slant plate groups C, C' and are precipitated into the grooves 2, 2' through the slant bottoms 1, 1'. The sludge thus precipitated is discharged to the exterior of the precipitating tank A by the screws 3, 3'. On the other hand, the sewage cleared of flocs is rectified by rectifying walls, is guided by guide walls and is fed to the next step through a water intake pipe. When the precipirating operation becomes unnecessary, the sewage is fed from the flocculator into a filter through a short-circuit passage 8.

Abstract: PURPOSE:To saturate a liquid with specific gas within a short time, by providing a hollow rotary shaft receiving rotational driving through the gear fixed to a drive shaft and a speed increasing shaft rotating at an angular speed two times that of the drive shaft through the gear to said drive shaft. CONSTITUTION:A gear 18 is fixed to an eccentric shaft 41 through a spacer 17. Now, when a drive shaft 24 rotates at an angular speed -1omega, a rotary shaft 51 rotates at an angular speed 1omega and the eccentric shaft 41 revolves at the angular speed 1omega outside the rotary shaft 51. A speed increase shaft 39 rotates at an angular speed 2omega and, as a result, the eccentric shaft 41 rotates in a self-centered manner at an angular speed -2omega but, because already revolves at the angular speed 1omega, rotates at the angular speed -1omega corresponding to the difference between angular speeds -2omega, 1omega. As a result, the eccentric shaft 41 always rotates outside the rotary shaft 51 during motion, for example, in a state facing the north.

Title: Manufacture of fluid catalyst for gas phase contact oxidation of o-xylene
Inventor: ASAMI YUKIO
IPC: C07D307/89
Filed: 1988-06-29
Abstract: PURPOSE:To obtain highly activated and highly selective catalysts with adequate strength and appropriate bulk specific gravity by using titanium hydride which produces titanium oxide with crystallites of less than a specific diameter as a titanium oxide source for catalysts for the manufacture of phthalic anhydride. CONSTITUTION:After mixing a titanium oxide source, a vanadium compound, an alkali metal compound and a sulfuric acid compound, the mixture is atomized, dried and baked to obtain catalysts for the manufacture of phthalic acid containing vanadium pentoxide, an alkali metal compound, sulfuric acid and titanium oxide. At that time, titanium hydride is used, as a titanium oxide source, which produces titanium oxide with a crystallite diameter of 300Angstrom  or less. The catalyst thus obtained has ideal specific surface area and porous distribution, so that it is highly activated and also highly selective even at a low reactive temperature. In addition, the catalyst has high abrasion resistance, an appropriate bulk specific gravity and superior fluidity. Therefore, it produces phthalic anhydride at a high yield.

Abstract: PURPOSE:To obtain an oxide superconducting material having a specified compsn. by using as a starting material an aq. soln. of metals contg. a tert. alkylamine and/or quat. alkyl ammonium hydroxide as coprecipitating agent or pH adjuster and coprecipitating metal components from the aq. soln. CONSTITUTION:An oxide superconducting material is obtd. by using, for example, an aq. soln. of metal salts consisting of salts of Y, Ba, and Cu, as starting materials and coprecipitating metal components in the presence of a coprecipitating agent or a pH adjuster described hereunder. The useful coprecipitating agent or pH adjuster is tertiary alkylamine (e.g., triethylamine) and/or quat. alkyl ammonium hydroxide (e.g. quat. tetraethyl ammonium hydroxide). Since these compds. are org. compds., the may be removed by decomposition in the calcination stage even if they are left by being adsorbed to the surface of solid phase after coprecipitation. Moreover, formation of cuparammine complex ion can be prevented. Accordingly, since whole of the Cu component is adsorbed to the coprecipitate, an oxide superconductor having a specified compsn. is obtd.

Title: Protecting circuit
Inventor: SATOU YOSHIHIRO
IPC: H01L27/02
Filed: 1981-10-12
Abstract: PURPOSE:To obtain a protecting circuit which prevents a circuit damage due to overcurrent when an overvoltage is applied to a power source terminal by positively varying the resistance value of a channel with the power source voltage and controlling the current. CONSTITUTION:Numeral 1 designates an Al electrode in the drawings, and VDD is applied to the electrode. Numeral 2 also designates an Al electrode, which is connected to an adjacent internal load circuit. Numeral 3 designates an N<+> type diffused layer 4 forming a channel, and 4 a P type semiconductor substrate which is connected to the ground. Numeral 5 designates an insulating layer, 6 a P<+> type diffused layer formed in the layer 3, and 7 an Al electrode connected to the ground. When VDD is applied to the electrode 1, a depletion layer is formed around the layer 6. A current flowing through the layers 1, 3 and 2 is controlled by this depletion layer. In other words, when the VDD is raised, the voltage of the layer 3 is raised and the depletion layer is extended, thereby causing the current to hardly flow.
