Title: Laser beam processing method
Inventor: TANAKA AKIO
IPC: B23K26/38
Filed: 1984-12-28
Abstract: PURPOSE:To expand the cutting range of an acute angled part by changing intermittently and stepwise the relative moving speed of a torch for laser cutting and work near the vertex of the acute angle diagram. CONSTITUTION:The cutting by laser light is once stopped near the vertex of the acute angle diagram and the intermittence of cutting with the stop time a1-a5 and the moving time b1-b5 is repeated for a slight distance to decrease the delay of a drag line as far as possible in the starting part of the recutting. The cutting speed is stepwise increase in this stage. The optimum value for the cutting material is selected for the number of cutting and stopping. The cutting limit of the acute angle cutting where the limit exists heretofore on account of a delay in the drag line is expanded with the decrease of the delay in the aray line by the above-mentioned method. The cutting range is therefore considerably expanded.

Title: Method for refining zinc
Inventor: TAKAHASHI JUNICHI
IPC: C22B19/32
Filed: 1991-09-27
Abstract: PURPOSE:To refine a zinc with a little heat consumption by solidifying while extruding a part of the zinc from molten zinc metal containing impurities. CONSTITUTION:A part of the zinc is solidified while extruding from the molten zinc metal containing impurities. The extruding speed of the part of the zinc is desirable to be 1 5mm/hr. At the time of solidifying, the difference of a distribution ratio at the time of equilibrating in the impurities of lead, cadmium, etc., at a solid-liquid interface of the zinc metal is utilized.

Abstract: PURPOSE:To certainly supply delivery pressure oil to a highly loaded actuator by forming an operating valve in a pilot actuating type, and providing a delivery passage of a pilot pump with a relief valve whose relief pressure alters according to differential pressure between load pressure and the delivery pressure. CONSTITUTION:An operating valve 2 is formed in a pilot actuating type, and a delivery passage 10a of a pilot pump 10 is provided with a relief valve 13 whose relief pressure alters according to difference between load pressure P1 and delivery pressure P2. An initial pressure P0 of the pilot pump 10 therefore becomes low when a difference between the load pressure P land the delivery pressure P2 is large, and high when the above difference is small, and if a stroke of an operating lever 11 is the same, pilot pressure supplied from a pressure control valve 12 to the operating valve 2 becomes low or high according to a size of the differential pressure to narrow or widen the opening of the operating valve 2, which narrows in the case of the high load pressure P1 to prevent the sum of flow rates to the actuator from exceeding the pump delivery rate for preventing the no supply of the delivery pressure oil to the actuator having the high load pressure.

Title: Shield connector
Inventor: SANO KAZUAKI
IPC: H01R4/64
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a shield connector in which the number of parts is decreased. SOLUTION: When a shield connector is fixed to a shield wire 10, a receiving piece part 35 of a terminal metal 30 is inserted into a shield layer 13 of the shield wire 10 and the receiving piece part 35 is bent under that state to caulk the shield layer 13 while sandwiching between a caulk piece part 36 and the receiving piece part 35. The terminal metal 30 and the shield wire 10 are then set in a die and a housing 21 is molded thus fixing the shield connector to the shield wire 10. Since the housing 21 is insert molded to the shield wire 10, number of parts is limited. Furthermore, assembling work is facilitated because the terminal metal 30 is connected with the shield layer 13 by simply caulking the shield layer 13 while sandwiching between the receiving piece part 35 and the caulk piece part 36.
