Title: Laser gauge interferometer
Inventor: TAKAHASHI YOSHIHIKO
IPC: G01B9/02
Filed: 1984-06-13
Abstract: PURPOSE:To compensate a range measuring error and to obtain high precision and high stability by separating a reference reflection mirror and a reflection mirror for measurement from a beam splitter by nearly the same distance. CONSTITUTION:This interferometer is equipped with a laser head 1, the beam splitter 2, the reflection mirror 5 fixed to it, the reference reflection mirror 3, and the reflection mirror 4 for measurement which is arranged nearly as far away from the beam splitter 2 as the reflection mirror 3 in the same direction. In this constitution, reference laser light L2 is reflected by the reflection mirror 3 toward the reflecting mirror 3. This light L3 is reflected by the reflection mirror 3 to return and travel to the splitter 3 through the mirror 4. The light L3 varies in wavelength depending upon fluctuation of air, which causes a variation error, but the phase difference between the light L2 and L3 does not appears when they are multiplexed by the splitter 2 although both light beams are affected by the fluctuation of air almost to the same extent, so no measurement error appears.

The deposition plate is subjected to the heat treatment after the magnetic metallic films 4 and the insulating films 5 are sputtered on the nonmagnetic substrate 3 and before glass for joining the two core blocks is packed. As a result, the prior desorption of the gaseous Ar included in the magnetic metallic films 4 and the insulating films 5 at the sputtering is made possible.

IPC: B21B33/02
Filed: 1978-09-30
Abstract: PURPOSE: To prevent damage of the pass roll and get rid of decline of the rate of operation, by deriving from the action moment the stress which is generated in the pass roll, and controlling depending upon whether or not the product of the foregoing and the coefficient of notch of the roll is smaller than the fatigue strength of the roll.  
     CONSTITUTION: Bending and torsional moment Mb, Mt act upon both the rolls by the rolling material carried between the upper and lower rolls 3, 4 which have received the rolling force of the rolling mill 1 of shape steel. The stress σm which is generated in both the rolls can be calculated by the expression I (d:roll diameter). At first, the rolling schedule of the rolling mill and also the roll constant are selected, and after confirming whether the screw-down and screw-up setting value is abnormal or not, the driving motor consumption power and the stress σm are derived by working the load cell 6. And in case the expression 4 (β, OR: coefficient of notch of roll, fatigue strength) ends in failure, the roll is released from the rolling material and simultaneously the rolling mill is stopped, through the cylinder 9 by transmission of the controller 11. In case the expression II is worked out, the usual screw-down control is carried out.

IPC: H01L21/58
Filed: 1979-09-21
Abstract: PURPOSE:To reliably arrange chip-type elements one by one by vertically piling them up in a square hole, inserting one of them into the square opening in a scraping-off plate which is horizontally moved together with the chip-type element, and dropping it into the opening of a bottom plate. CONSTITUTION:Chip-type elements 2 are vertically piled up in a magazine 3, and a dead weight is put on them. The lowest element 2a is placed on the upper surface of a guide plate 18, and the magazine 3 is stopped by means of a stopper 15. When a scraping-off plate 17 having a square opening 17' into which the element 2a is inserted is moved to an opening 18' of the guide plate 18, the element 2a drops into an opening 19' of a pallet 19. Allowing the scraping-off plate 17 to move in the direction of 45 deg. permits an extremely stable mounting. The constitution permits the elements to be once arranged on the pallet one by one and then to be arranged on a substrate by the attraction of a vacuum. Therefore, two elements can be attracted at the same time.
