Abstract: PURPOSE:To improve the adhesiveness of a mask to an object to be exposed and improve the accuracy of the exposure by a method wherein, when the mask is stuck to the object, a process which eliminates air easy to remain between the mask and the object is provided. CONSTITUTION:After a high concentration active layer 4 which is to be a drain region and an active layer 5 which is to be a channel region are formed in a semiconductor substrate 1 such as a GaAs substrate by a method such as ion implantation, an insulating film 2 is formed on the substrate 1 and patterned and ohmic electrodes 3 which are to be source and drain electrodes are formed by a known technology such as lift-off. Then a resist layer 6 is formed on the insulating film 2 and patterned to form apertures 7 is regions which have no influence upon the formation of an FET and the parts of the insulating films 2 exposed in the apertures 7 are removed by etching to form trenches 8. After the resist layer 6 is removed, a new resist layer 9 is formed over the whole surface and a mask 11 for forming a gate is stuck to the resist layer 9. When the mask 11 is stuck to the resist layer 9, air remaining between the mask 11 and the resist layer 9 is evacuated through recessed parts 10 so that the adhesiveness can be improved.

Title: Accumulation conveyor
Inventor: YAMAYORI SHINGO
IPC: B65G13/071
Filed: 1994-04-28
Abstract: PURPOSE:To provide a device for carrying out secure accumulation operation by interposing freely rotating rollers between work-conveying rollers and an endless belt being endlessly turned by a motor so as to be capable of being connected or disconnected. CONSTITUTION:When a sensor 20 detects a downstream work 21 to stop the subsequent work 21 on rollers 4, the rod of an air cylinder 14 is shortened. Then, a roller frame 15 connected thereto is pulled, and also a set of rollers 16 moves on the rail. Since the rollers 16 are separated from the rollers 4 and are positioned between two rollers 4, the movement of a transmission belt 8 is transmitted only to the rotation of the rollers 16 and is not transmitted to the rollers 4. When there is no work 21 on the downstream side, the rod of the air cylinder 14 is elongated. Then, the roller frame 15 is pushed, and a set of rollers 16 move on the rail, and the respective moving set of rollers 16 are interposed between the respective rollers 4 and the transmission belt 8, and the rollers 4 are turned by the rotation of the abutting rollers 16.

If the magnetic conductor 17 is turned off, the machine, eliminating a stray capacity of the machine main unit itself and a stray capacity between a wire electrode and the machine main unit because the work 13 is electrically insulated from the machine main unit by an insulating jig 21 mounted to the surface plate 4, enables energy by a capacitor discharge, generated when electric discharge machining is performed, to be suppressed, and the machine, decreasing single shot discharge energy, obtains fine roughness of a machined surface in the work. The machine can automatically perform general machining and finishing by switching the insulation through the magnetic conductor.

Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To enable the ultraprecise measurement of the load and residual stress of machine parts which receive thermal stress and stress fluctuations, the axial tension of bolts, the elastic modulus of various materials, and internal wear. SOLUTION: A polymer-quality damper 3 and a substrate shaped piezoelectric element 4 are at least assembled in the case 2 of an ultrasonic transducer 1. The inner surface 4a of the piezoelectric element 4 is provided with an electrode 7 to be connected to a lead wire 6a, and the outer surface 4b is constituted so as to directly come into contact with an object to be measured. Two polarized types of a piezoelectric domain for generating longitudinal waves and a piezoelectric domain for generating transverse waves are present in the piezoelectric element 4, and ultrasonic waves in longitudinal and transverse waves are simultaneously transmitted from the piezoelectric element 4 toward the object to be measured at the time when a voltage is impressed through the use of the above-mentioned electrode 7 and the object to be measured.  By this, it becomes possible to measure ultrasonic waves in longitudinal and transverse waves simultaneously and to measure an undispersed mixed-phase structure without being restricted by the thickness of a sample.

Title: Hot rolling method for aluminum alloy slab
Inventor: KOUBI MITSUO
IPC: B21B1/02
Filed: 1981-07-21
Abstract: PURPOSE:To prevent the generation of abnormality in surface characteristic and to improve the yield and efficiency in hot rolling of aluminum alloy slabs by cutting off the top and bottom surfaces in the bottom part of said slabs properly then rolling the same roughly in the longitudinal direction. CONSTITUTION:In hot rolling of an aluminum slab of Al-Mn and Al-Mg, the top and bottom surfaces in the bottom part of the slab prior to rough rolling are cut to 1/5-1/3 the overall thickness of the slab respectively at an angle alpha of 45-70 deg., more preferably 60 deg.; thereafter the slab is roughly rolled in the longitudinal direction. Then even if the slab wherein the ruggedness in the bottom skin part occurring in casting stages and the segregation layers of extremely high hardness produced inevitably exist is rolled, the generation of strong gnawing marks, mouth cracking of aligator parts, etc. is obviated; therefore, an increased yield is resulted from decreased cutting parts, and rolling efficiency is improved by the elimination of the need for return rolling. Since the central part (a) of the thickness is concealed internally by overlapping during rolling, there is no need for removing said part.

Abstract: PURPOSE:To obtain a conductive layer having reliability by a method wherein layer stress restraining areas distant each other are provided in the direction of extension of the conductive layer, and then thermal stress strains are reduced therein. CONSTITUTION:The numeral 5 represents the conductive layer composed of a polycrystalline Si film 6 formed on gate dielectric films 3 which constitute each MOS transistor and on field oxide films 4 existing between these gate dielectric films 3 and of a molybdenum silicide film 7 formed by lamination on this polycrystalline Si film 6, and the numeral 8 represents the layer stress restraining areas formed thinly by performing etching to the polycrystalline Si 6 on the field oxide films 4.
