IPC: G01B11/30
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To absolutely calibrate a flatness of a mirror face by making rotationally symmetric a recessed part of a container storing a fluid giving a fluid surface to be a reference plane. SOLUTION: Generally, a 63.3nm He-Ne light is projected as a plane wave from an interferometer main body 5, reflected by fold mirrors 31, 33, 35 in a stage 3 and brought into a Fizeau flat 37. A liquid face 41a as a face of a reflex master standard is formed by setting a fluid body 41 in a spherical ball container 39. A flatness error is maintained even when the whole container tilts. The container is held to be able to shift in a vertical direction to an optical axis 11c of the interferometer. Components except for the interferometer main body 5 are mounted on the stage 3 not to drift after a Fizeau face 37a and the liquid face 41a are aligned. A moving mechanism 45 is moved at low speed so as to reduce a tilt change of the Fizeau face 37a caused by a load change acting on the stage 3.

Title: Turning machine
Inventor: KAMIYA YASUO
IPC: B23B1/00
Filed: 1986-02-04
Abstract: PURPOSE:To lengthen the service life of a cutter and to improve the accuracy of a finished face, when turning a shaft formed with a key groove, a spline, etc., by setting an endface cutter off in the radial direction thereby preventing a cutting edge from falling into the key groove. CONSTITUTION:Two cutting edges 23, 23 are inclined by an angle (a) in the radial direction. Since the cutting edges 23, 23 obliquely traverse a groove C etched in a work W and perform the cutting with a portion thereof abutting continuously against the outer circumference of the work W, the edges 23, 23 never fall into the groove C. Even when the cutting edges 23, 23 are in parallel with the groove C, they are prevented from falling into the groove C because the gap D between the cutting edges 23, 23 is made larger than the width (d) of the groove. Since there is no vibration nor impact associated with the falling of the cutting edges, the service life of the cutter is lengthened and the accuracy of the finished face is improved.

Title: Wiring method of adjusting delay time of clock signal in semiconductor integrated circuit
Inventor: ADACHI KOJI
IPC: G06F15/78
Filed: 1992-02-06
Abstract: PURPOSE:To obtain an automatic wiring capable of forming a semiconductor integrated circuit with a high speed of operation, by adding a wiring pattern to output pins of clock amplifiers so as to have the same load capacity of the output pins. CONSTITUTION:Since a clock signal is inputted to an input pin 5 of a flip-flop F from an external clock pin P1 and a distribution system by a clock phase is installed in a semiconductor integrated circuit and each clock amplifier has the different number of loads respectively, the difference between delay times of the clock signal occurs. Then, the wiring length of wiring L added to working pins P3 is obtained for not only the working pins P3 but unworking pins P4 out of output pins of the clock amplifiers and a wiring pattern LP with the same length as the obtained length is added. Therefore, since each clock amplifier has substantially the same load capacity of the output pins, the dispersion of the delay times caused by gates of the clock amplifiers can be reduced and the semiconductor integrated circuit can be operated at a high speed.
