IPC: B23K9/00
Filed: 1994-12-14
Abstract: PURPOSE: To prevent the occurrence of distortion in a first member when a second member is welded to a welding position on one side of the first rod- shaped member. CONSTITUTION: Each end part of a first member S is supported by a pair of supporting means 4, 5 to achieve the positioning in the rotational and axial directions, and a second member P is positioned by a positioning means 9 so as to be abutted on the welding position wp on the back surface of the first member S. The upper surface of the first member S is pressed downward by a pressing means 19 to be bent so as to be abutted on a pair of stopper bolts 24, and in this condition, the second member P is welded to the welding position wp of the first member S. The bending due to the cooling and contraction of the welding position wp is canceled by achieving the welding while the first member is bent in the opposite direction, and a product free from the distortion is obtained.

Filed: 1993-11-17
Abstract: PURPOSE:To realize stabilized driving by specifying the output from a pattern generator generating a function output being selected arbitrarily by the frequency of a command pulse train and controlling the exciting current of a pulse motor variably thereby sustaining the torque at a substantially constant level over the entire rotational speed range. CONSTITUTION:An excitation command value, i.e., a command voltage Vomega, of a pulse motor 6 is an output from a pattern generator 1 generating a function output selected arbitrarily from the frequency fM of a rotational speed command train for the pulse motor 6 and the output is employed as a command value for the pulse motor 6 in the variable control of exciting current.

Title: Narrow band excimer laser
Inventor: SAITO TAKASHI
IPC: H01S3/03
Filed: 1990-11-16
Abstract: PURPOSE:To obtain an efficient narrow band laser light by constituting a discharge space which has a pair of discharge electrodes, a resonator comprising a light emitting mirror and a total reflecting mirror and a dispersion device and a specific discharged band. CONSTITUTION:Laser light 10 excited in a discharged space 12 is dispersed when it enters a dispersion device 13. When it is turned back by a total reflecting mirror 15, it is emitted from an emitting mirror 14, passing through the dispersion device 13 and the discharge space 12 once again. Since the discharge space 12 has a discharge band given by an equation, an unnecessary portion of the laser light dispersed by the dispersion device 13 is removed without inserting an aperture, thereby obtaining laser light with a narrow spectral width. This construction makes it possible to use effectively energy injected into the discharge space and take out effectively the laser light having a narrow spectral width.

Abstract: PROBLEM TO BE SOLVED: To provide a detection apparatus which is provided with a fail-safe output error characteristic and by which the change state of an input signal is detected surely without being effected by a vibration, a shock or the like. SOLUTION: A signal in which a high-frequency AC signal ω2 , is superposed on an input signal e1 is input to a capacitor C4 via a switching element SW1.

When the difference between an input level with the switching element SW1 turned off and an input level with the switching element turned on is at a prescribed value or higher, the output of the amplifier 12 is saturated, and the AC portion of the input signal is not transmitted to an amplification output. In a voltage doubler rectifying circuit 13, an oscillation output which indicates no change in the level of the input signal is generated from a fail-safe window comparator WC1 when the AC portion of the output of the amplifier 12 is rectified and when both a rectification output via an off-delay capacitor C7 and the input signal e1 are at a high level.
