Title: Spot welding machine with welding transformer
Inventor: OKABE YOSHIO
IPC: B23K11/11
Filed: 1983-05-13
Abstract: PURPOSE:To reduce weight of a welding machine and electric power consumption by providing a sliding power feed part to the secondary circuit of the welding machine in such a way that the secondary winding of a transformer constituting said circuit is movable relatively with iron cores and can deal with the pressing operation of a gun as well. CONSTITUTION:Iron cores 11, 12 are inserted to a secondary coil 10 consisting of pipe-shaped conductive members 10A, 10B to constitute a transformer 8 which is brought into contact with the members 10A, 10B slidably therebetween by a power feeder 16. The transformer 8 is fixed to a robot arm and works are positioned between the electrode chips 6 and 7 of a gun 1. A piston 14, that is, the member 10A, is moved according to the operation of a pressing cylinder supported by an equalizing mechanism 25 and the member 10B is relatively moved when the cylinder 13 is floated by the reaction of the pressurization. The need for a flexible tube of a spot gun with a transformer is thus eliminated, and the area of the space enclosed by the secondary circuit is decreased. The weight and electric power consumption is thus reduced.

Title: Radiation detecting element
Inventor: HATANAKA YOSHINORI
IPC: H01L31/09
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce junction defect between respective layers by employing a material having a grating constant close to that of a radiation detecting layer in p layer and n layer constituting a radiation detecting element. SOLUTION: A radiation detecting layer 11 is formed of a single crystal Cd0.9Zn0.1Te of 1 mm thick having resistivity of 1010 Ω.cm and the upper surface thereof is doped with p type impurities of form a p type Cd0.9Zn0.1Te layer 13 while the lower surface thereof is doped with n type impurities to form an n type CdSe0.1Te0.9 layer 15. Since the Cd0.9Zn0.1Te forming the radiation detecting layer 11 and the CdSe0.1Te0.9 have grating constants close to each other, junction defect due to difference of grating constant can be reduced by forming the n layer of CdSe0.1Te0.9 and forming the p layer of same material as the radiation detecting layer 11. Consequently, leak current of a radiation detecting element 10 can be suppressed significantly as compared with a radiation detecting element 10 having neither p layer nor n layer.

IPC: G05B11/32
Filed: 1993-03-17
Abstract: PURPOSE:To estimate disturbance generated in a power transmission mechanism and disturbance to be impressed to the output side of the mechanism part and to remove the influence of disturbance by applying a control model consisting of the dynamic characteristic of a machine system and a disturbance model to the positive efficiency gain and reverse efficiency gain of the mechanism part. CONSTITUTION:The feedback values X1 to X3 of a load side status amout including torque ripple D1 generated from the power transmission mechanism 14 are estimated by an observer 2 and subtracted from a torque command T by an adder 1. The positive efficiency gain eta+ and reverse efficiency gain eta- of the mechanism part 14 are applied to the control model consisting of the dynamic characteristics of the machine system and the disturbance model. The gain eta+ is multiplied at the time of transmitting an output signal from a servo motor 11 to a robot arm 15 and the gain eta- is multiplied at the time of negatively feeding back the output signal in the reverse route. Consequently the whole system can stably be controlled by the removal of disturbance, the reduction of oscillation at the time of resonance with the machine system and the like.
