Title: Oxygen discharge nozzle for removing metallic defect and metallic defect removing method
Inventor: FUHRHOP RONALD ELMER
IPC: F23D14/68
Filed: 1987-10-21
Abstract: PURPOSE: To obtain a scarfing nozzle for automatically controlling without generating a fin by admixing a gas with an oxygen so that a purity of the oxygen of one edge of a sheet-like stream of oxygen is of reduced privity insufficient to scarf, while a purity of the oxygen or the remainder is sufficient to scarf defects on a surface of the metal. CONSTITUTION: A continuous slot-like scarfing nozzle 15 having a discharge orifice 20 is formed of a lower surface 11 of an upper preheating block 12 and an upper surface 13 of a lower preheating block 14, and a sheet-like stream V of scarfing oxygen is discharged. The stream of the oxygen discharged to both side ends of the orifice 20 is admixed with a gas of an amount for reducing a purity of the oxygen insufficient to scarf. And, a flowing velocity of the gas at a side edge of the orifice 20 is advantageously substantially the same as a velocity of the sheet-like stream of cutting oxygen of uniform intensity across the surface of a metal. However, the stream at the edge becomes fast. The flowing velocity of the oxygen supplies a momentum of removing a slag and a steel not yet oxidized, thereby performing a good result of generating no fin.

Title: Baking device for ceramic substrate
Inventor: OTANI HIROYUKI
IPC: F27D5/00
Filed: 1990-10-01
Abstract: PURPOSE:To prevent the generation of warpage caused by the shrinkage difference of a ceramic substrate due to a temperature difference between the upper surface and the lower surface of the same in baking process by a method wherein the baking device is provided with a second muffle, consisting of a ceramic or a metal, at a predetermined position in a first muffle. CONSTITUTION:The title device is constituted of a tubular metallic first muffle 6, made of Inconel, a mesh belt 7, made of Inconel, a heater 3, heating from the outside of the muffle 6 by electric heat, and a second muffle 8, provided in the first muffle 6, while the second muffle 8 is constituted of a top plate 9 and side plates 10, which are made of alumina. According to this constitution, a temperature difference between the upper surface and the lower surface of a ceramic substrate is reduced remarkably by shielding the radiation heat such as near infrared rays and the like which raises the temperature of the upper surface of the ceramic substrate remarkably. On the other hand, when the ceramic substrate is constituted of other ceramics material and the shrinkage starting temperature is different, the second muffle is made movable and a baking device having a structure capable of moving and setting the substrate to and arbitrary temperature zone easily, is employed.

Title: Timer operation controller
Inventor: MORIMOTO MASAO
IPC: H01H43/04
Filed: 1987-10-20
Abstract: PURPOSE:To make any trouble in a mechanical pushbutton switchgear and the set miss of a timer checkable by stopping the operation of equipment upon operating a release lever of the mechanical pushbutton switchgear with an operator of the mechanical timer. CONSTITUTION:One end of a release lever 12 is projected from the side of a switch frame 5, thereby forming an operating projection 22 to be operated by an operator 21 of a mechanical timer 20. In such a state that the timer 20 shows 'off' indicated by a pointer part 25 of a control knob 24, the release lever 12 of a pushbutton switchgear 1 comes into a state of being pressed and slidden by the operator 21 against an elastic body 13. Consequently, even if a selector button 8 is pressed, it is not engaged, and when pressing force is loosened, it is restored to the original position by the elastic body 10. Thus, such a state that is set to the 'off' position of the timer 20 is informed to a user when the pushbutton switchgear 1 has been operated, so that a mistake is prevented from regarding it as trouble.

Abstract: PURPOSE:To provide transfer of pallets between conveyors with two or more lanes by furnishing a traverse device which reciprocates between the conveyors, and therein controlling the reciprocation according to detected arrival of any pallet and the sensing results on the features of the object concerned. CONSTITUTION:When a pallet 4 is transported by conveyors 1, 2 to a traverse device 11, approach switches 17 are turned on, and a control device 22 judges which pallet has arrives first before and after the ON timing, while an armature core set on the pallet is judged for before or after coiling through a photo-electric switch 18 being on or off, together with judgement where the request signal is generated. If a pallet 4 from conveyor 1 has come first and the signal is generated in the position further understream the device 11, a movable member 12 moves toward the conveyor 2, and the pallet 4 shifts to the same side. In the case a pallet 4 from conveyor 2 has come first and the signal is sent from the position following the device 11, the said member 12 is moved toward the conveyor 1 and the pallet 4 shifts to the same side. Thus pallets 4 can move freely between the conveyors.

Title: Management device for production quantity
Inventor: YASUDA AKIMOTO
IPC: G06Q50/00
Filed: 1990-10-02
Abstract: PURPOSE:To improve the working efficiency of an operator, by specifying a counter that addition, substraction or substraction operation is allowed from plural counters in accordance with the contents of a program or the kind of a work program. CONSTITUTION:A counter is equipped with plural counters, and the counter by which addition or substraction operation is allowed according to the kind of a work program or the program content by a counter specifying means from the plural counters thereof, is specified. The specified counter stores the accumulated number with the addition or substraction by the specified number whenever the work program is executed. So only the counter corresponding to the kind of work becomes to perform addition or substraction operation because the work program differs on each kind of the work. As a result, the accumulated number corresponding to the individual production quantity of the work is stored with the counter specified from the work program only being operated irrespective of the execution order of the work program. The work efficiency of an operator is thus improved.

CONSTITUTION:A substrate 3 for epitaxy supported by a jig 2 for epitaxy and a material 4 for epitaxy are loaded into an ampoule 1 and thereafter, this ampoule 1 is evacuated to a reduced pressure, is sealed and is put into a heating furnace. The material 4 is melted by heating to about 500 deg.C and thereafter, the temp. is lowered. The ampoule 1 is rotated to bring the molten material 4 into contact with the substrate 3 when the temp. to cause recrystallization is attained. The HgCdTe crystal layer is thus grown on the substrate 3. The crystal layer is thermally annealed for the necessary time at 200 to 400 deg.C after the growth of the crystal layer. The ampoule is taken out of the furnace and is rapidly cooled after the desired concn. of the p type carriers is attained. A method of growing the HgCdTe crystal layer by ordinary MOCVD or MBE in place of the ampoule and annealing the crystal layer is executable as well.
