Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a clamp device for jigs preventing interference with a welding gun even when the welding gun is moved along the peripheral part of a work W1. SOLUTION: A clamp cylinder 71 is arranged on a jig 1 so that the cylinder falls within the plane of projection (the plane of projection of the work) in the vertical direction of the work W1 and the axial line of the cylinder is inclined obliquely upward toward the outside of the plane of projection of the work. A clamp arm 70 is connect to a clamp cylinder 71 so as to be linearly moved in the direction of the axial line of the cylinder and also a pawl part 70b which is bent to the side of the clamp cylinder 71 is formed in the tip part of the clamp arm 70 while allowing an upward rising part 70a to exist therein. When the clamp arm 70 is moved on a closed side where the arm approaches the clamp cylinder 71, the pawl part 70b enters in the plane of projection of the work and brought into contact with the top of the peripheral part of the work W1.  When the clamp arm 70 is moved on a opened side where the arm is away from the clamp cylinder 71, the pawl part 70b is made to be detached outside the plane of projection of the work.

Title: Tungsten material and its manufacture
Inventor: UMEDA YASUSHI
IPC: B32B15/01
Filed: 1991-12-25
Abstract: PURPOSE:To provide an inexpensive tungsten wire rod having sufficient alkali resistance particularly platinum-plated tungsten wire rod by successively forming a layer contg. gold or copper and a layer contg. nickel on the surface of tungsten wire rod. CONSTITUTION:A primary layer contg. gold or copper is formed on the surface of tungsten wire rod by plating, and a secondary layer contg. nickel is formed thereon by plating. Gold plating is preferable because it prevents the diffusion of nickel into tungsten when it is applied as strike plating. Furthermore, in addition to the secondary layer, gold as well as platinum can successively be plated. By applying the strike plating of gold to the space of the nickel plating and platinum plating, the adhesion between the nickel plating and the platinum plating can be improved.

Title: Heater controller
Inventor: KITAMURA SHINGO
IPC: H05B3/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent the overlapping of rush currents by deviating the power supply control starts of plural heaters and to suppress the increase of power by executing the time division control of the plural heaters. SOLUTION: A lower heater is turned on after a delay of a time tW1 from the time TS when an upper heater is turned on. The time tW1 is of the rush current attenuation time of the upper heater and changed according to the temp. of the upper heater, so that the time tW1 corresponding to the temp. is adopted. Since the lower heater is turned on after the rush current of the upper heater is obtained, the increase of the power caused by the overlapping of the rush currents is prevented. After that, the upper and lower heaters are alternately turned on to execute the time division control. Thus, the increase of the power is prevented.

IPC: B41J29/50
Filed: 1989-12-28
Abstract: PURPOSE:To make it possible to set a printing range easily for sheets of all sizes by providing a carrier position measurement device and a switch for entering the position of an end of the printing range on a serial printer. CONSTITUTION:If a linear sensor is effectively set using a switch 4 after the homing of a printer due to the turning ON of a power supply a linear sensor 2 stores a reference point as the first step of a printing range setting process. Then a carrier 10 is moved using a switch 3 and thereby a setting switch 5 is depressed at the end of a movement range required for the carrier 10. Furthermore, the setting switch 5 is depressed at the other end again to set a printing range. However, if a power supply for the printer is shut off, the printing range is reset. If the switch 4 is changed over to 'linear sensor invalid', a printing range is set to an initial value which is set by the turning ON of the power supply for the printer.

IPC: H01L31/0264
Filed: 1992-12-24
Abstract: PURPOSE:To make it possible to change an Al composition to control a detection infrared wavelength without changing a superlattice structure, by forming a mesa structure in a specific superlattice in which an epitaxial growth is performed on an insulating substrate and mounting a pair of electrodes on the side of the mesa structure and applying a bias current in a superlattice plane direction of the mesa structure. CONSTITUTION:An epitaxial growth for 150 periods of an Al0.5Ga0.5Sb5nm/InAs10nm superlattice 3 is performed on an insulating Gaps substrate 1 through a GaSb buffer layer 2 with a thickness of 1mum. This superlattice layer 3 is worked in a mesa structure and a pair of Au electrodes 4 are mounted on the side of the mesa. When infrared rays are detected, by applying a bias current in a layer direction of the Al0.5Ga0.5Sb5nm/InAs10nm superlattice 3 from both the ends of the electrodes 4, a variation in voltage occurs in both the ends of the electrodes 4 due to a carrier caused by irradiation of the infrared rays, and thus this variation is read out. An Al composition x is not limited to 0.5 and is changed (x>0.3) and a cut-off wavelength is controlled.
