Title: Formation of diffraction grating
Inventor: OKAI MAKOTO
IPC: G02B5/18
Filed: 1985-05-15
Abstract: PURPOSE:To make possible the formation of a diffraction grating having lambda/4 shift by providing parts where a photosensitive material is coated and parts in direct contact with a soln. on a substrate surface and effecting positive reaction in one thereof and negative reaction in the other. CONSTITUTION:A positive resist is coated over the entire surface of a p-type InP substrate 1 by using a rotary type coating machine and a resist pattern 2 is formed by an ion milling method. A spacer 6 made of 'Teflon(R)' is held in place to the substrate and a quartz plate is fixed thereto by using clamping jigs. The spacing between the quartz plate 5 and the substrate 1 is filled with the soln. 8 contg. an org. material such as pyrrole which cures by oxidation reaction and is exposed for the specified time by an interference exposing method using an He-Cd laser. The pattern in which the parts 2' coated with the resist and the non-coated parts 8 are shifted by lambda/4 phase is formed when such substrate is developed. The resist is further etched by using an etching soln. (HBr:HNO3:H2O=1:1:34 by volume) by which the diffraction grating having the lambda/4 shift is formed on the surface of the p-InP substrate 1.

Title: Direction indicator
Inventor: ITOU HISATSUGU
IPC: G01C17/28
Filed: 1978-08-19
Abstract: PURPOSE: To enhance accuracy, viewability, and reliability for direction indicator, earth magnetism detection and its indication are electronically treated.  
     CONSTITUTION: Magnetic sensor 1 has two nearly perpendicularly crossed detection axes and produces electric outputs e x , e y  of external magnetic components which correspond to the detection axes. The magnetic sensor 1 is connected to amplifiers 21, 22, coefficient calculators 71 to 74, comparators 81 to 88, photoemitting elements 31 to 38. Thus, outputs e x , e y  from the magnetic sensor 1 are amplified, multiplied by coefficient α(=tan67.5°≃2.414), 1/α, -1/α, -α by the coefficient calculators 71 to 74, and compared each other by the comparators 81 to 88. This finds the zone to which the measurement belongs, from 8 zones determined by 4 straight center-passing lines. The result is indicated by lighting one of photoemitting elements 31 to 38 so that lighting corresponds to measured zone.

Filed: 1979-08-08
Abstract: PURPOSE: To obtain a tuning device having a reversible tuning control function by providing a differential mechanism and a responding mechanism as mechanical coupling means between the punch in the upper part and the punch in the lower part.  
     CONSTITUTION: The closed forging press is provided with a die closing press ram 3 and a pair of diametrically opposing punching rams 5, 6, which both make reciprocative motion along the common axial line. When a ram 5 for punch descends, the press ram 3 is held stopped; hence a slide rack 25 is held stopped as  well. However, along with descending of the ram 5 for punch, an intermediate  body 13 descends and the gear 19 meshing with the rack 14 turns while meshing  with the rack 26 of the slide rack 25, thereby inducing descending motion. The  extent of the descending is 1/2 that of the intermediate body 13. Thereupon, if the  gear ratio of the gear 22 and the gear 23 is kept at 1:2, the extent of ascending  forced to the intermediate body 15 in the lower part becomes equivalent to the  extent of descending of the intermediate body 13 and the extents of going-in of the  punch 7 and punch 8 become equivalent as well. In this way, the moving mechanisms are associatedly driven by a linkage system.
