Title: Pulse arc welding device
Inventor: NAGASAKA MORITOSHI
IPC: B23K9/09
Filed: 1981-02-02
Abstract: PURPOSE:To perform uniform welding with stabilization of the arc by controlling a switching circuit for pulse current by means of the difference between the signal of a welding voltage setting circuit and a welding voltage detecting circuit. CONSTITUTION:The output voltage of a base electric power source 1 is applied to a wire 3 and the work 4, and a wire 3 is fed whereby the arc is generated. The set signal Es which is the output from a welding voltage setting circuit 31 and the detection signal Ed of a welding voltage detecting circuit 32 are inputted to a comparator 33, the difference whereof is inputted to a V/F conversion circuit. The conversion circuit outputs a pulse frequency signal Ef, and supplies the same to an MM circuit of a switching control circuit 40. The MM circuit outputs the prescribed pulse frequency range signal Eft to a switching circuit 22. The circuit 22 operates only during the period when the signal Eft is supplied, so that the pulse current of the peak value is supplied from a pulse electric power source 20 to welding load R. After lapse of a prescribed time until the next operation start, the circuit 22 is held interrupted, and only the base current Ib is supplied to the load R.

Title: Composite roll for rolling and its manufacture
Inventor: SHIMOTAMURA OSAMU
IPC: C22C37/00
Filed: 1984-01-30
Abstract: PURPOSE:To prevent the generation of stripping and cracking in rolling even under high rolling reduction and high rotational speed by providing a boundary part, formed by changing continuously a material composition, to the space between a core material and a spray coating layer. CONSTITUTION:A thick spray coating layer 3 is formed by plasma-spraying a spray powder having spalling and wear resistances on the surface of the body part 2 of a core material 1 excellent in strength and toughness. The composition of components is changed continuously in sequence from the surface of core material 1 to the spray coating layer 3 between the material 1 and the layer 3. Accordingly, the continuous boundary part 4 formed between the material 1 and the layer 3, changes continuously in the distributions of hardness, component, and residual stress, and is therefore prevented from causing a stress concentration during rolling.

Title: Scroll type hydraulic unit
Inventor: SHIBAMOTO YOSHITAKA
IPC: F04C18/02
Filed: 1989-01-24
Abstract: PURPOSE:To reduce the extent of thermal effect on a refrigerant by connecting an outflow port being formed in a fixed scroll and a fluid discharge port of a casing through a discharging pipe, forming this discharge pipe into a double pipe structure of both outer and inner pipes, while installing a recess in a peripheral edge of the outflow port, and inserting an edge of the discharge pipe thereinto. CONSTITUTION:The side of a back face 7g of an end plate 7a of a fixed scroll 7 is interconnected to a refrigerant inlet port 5, forming a low pressure space there. Therefore there is no rise in temperature of a refrigerant in each of scrolls 7, 8 at all. On the other hand, a discharge pipe 14 is constituted of a double pipe structure consisting of an outer pipe 14a and an inner pipe 14b, and thereby the refrigerant stays in an interval between an inner circumferential surface of the outer pipe 14a and an outer circumferential surface of the inner pipe 14b, checking any heat conduction to a casing inner space of the refrigerant flowing in the inner pipe 14b. In addition, the end plate 7a of the fixed scroll 7 forms a recess 7b in a peripheral edge of an outflow port 7c and the discharge pipe 14 is inserted thereinto. A contact surface between a compressed refrigerant flowing into the discharge pipe 14 from the outflow port 7c and the end plate 7a is only in a thickness part of the recess 7b, and since a heat conduction area is small, any heat conduction to the end plate 7a is thus checked.
