Title: Method and device fork pouring gas in hollow molded article
Inventor: KURIHARA TSUNEO
IPC: B29C45/17
Filed: 1991-06-27
Abstract: PURPOSE:To maintain favorable appearance of the product by bringing the intrusion of gas in unnecessary part to null and surely pouring the gas in necessary part by a method wherein low pressure gas is poured in resin at the early stage of the molten resin, the surface layer of which is semi-solidified, and held for the predetermined period of time and, after that, high pressure gas is poured in the resin so as to mold a hollow molded article. CONSTITUTION:When the solidification of the surface layer of resin 42 starts, gas is poured for the first time. A needle pin 16 in its intermediate position is once lowered so as to make a hole in the surface layer and them moved upwards in order to introduce low pressure gas waiting in a gas flow path 22 into the resin 42 for pouring gas for the first time. The needle pin 16 is lowered again just after the opening of the gas flow path 22 so as to shut off the gas flow path and hold that state for the predetermined period of time. When the pressure of gas in a high pressure gas tank 26 is gradually elevated and then the pouring of gas is carried out for the second time or the needle pin moves upwards so as to oven the gas flow path 22 in order to introduce high pressure gas in the resin 42 and hold that state for the predetermined period of time, resulting in developing no intrusion state of gas in unnecessary part and consequently forming hollow part having favorable shape.

Title: Exposure method for electron beam
Inventor: TAKAYANAGI SHINJI
IPC: H01J37/317
Filed: 1980-12-24
Abstract: PURPOSE:To remarkably shorten a shotting cycle time in an exposure method for an electron beam by approximately apparently absorbing the digital arithmetic processing time of a DA converter in a position designating system to a shotting time or to a time of adding the shotting time to a settling time. CONSTITUTION:When the sum of a beam emitting time designation signal Tp and a signal TS corresponding to the responding time of a DA converter 5 in a position designating system and the difference (TP+TS-TD) of the signal TD corresponding to the digital arithmetic processing time of the converter 5 are positive, an electron beam is emitted, a time (TP+TS-TD) is elapsed, the position designation signal counted by two after the original signal is then fed to the converter 5. When the sum and the difference are negative, the beam is emitter, the time TD is elapsed, the position designation signal counted by two after the original signal is fed to the converter 5, thereby performing the exposure of the electron beam. In this manner, the shotting cycle time can be remarkably shortened, with the result that the exposure time can also be largely shortened.

IPC: G05B19/18
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To automatically limit feed rate at the time when the thermal expansion of a feed screw exceeds an allowable amount of change by executing a process for failures, if the amount of relative change calculated from the calculated relative positions exceeds an allowable amount of change. SOLUTION: The relationship, calculated by a subtractor 11, between the indirect position of a movable part 17 detected indirectly by a feed screw rotary angle detector 14 and the direct position of the movable part 17 detected directly from the slider 15 of a linear scale 16, varies depending on the amount of thermal expansion of a feed screw 18.

Title: One-dimensional effect element and manufacture thereof
Inventor: NIHEI FUMIYUKI
IPC: H01L29/80
Filed: 1989-07-19
Abstract: PURPOSE:To prepare the title one-dimensional effect element by a method in which the gate electrode and the gate voltage supply line are shaped collectively, and which is simpler than a method in which a gate electrode and a gate voltage supply line are formed discretely. CONSTITUTION:Only the upper layer section 31a of a region, in which a gate voltage supply line is shaped, in a positive type resist layer 31 applied onto a semiconductor substrate to which a GaAs layer and an AlxGa1-xAs layer are formed is exposed by ion beams 32. The exposed resist upper layer 31a is removed through developing treatment. A region 31b in which a gate electrode is shaped is exposed by electron beams 33. The resist 31b in the region exposed by electron beams is removed through developing treatment. Gate, electrode materials 34, 34a are evaporated from the upper section of the semiconductor substrate. Lastly, the finally left resist is taken off together with the gate electrode material 34a attached onto the region not exposed of the resist. Consequently, the gate electrode and a gate voltage supply source are formed collectively. Accordingly, internal resistance is lowered while the capacitance of the gate electrode and a channel is inhibited at a small value in an element prepared, and operating speed is not decreased.

Title: Method for retaining soft capsule in stable state in material to be incorporated
Inventor: MORISHITA TAKASHI
IPC: A23G3/00
Filed: 1980-12-25
Abstract: PURPOSE:To maintain the soft capsules in a material to be incosporated in an extremely stable state during producing process as well as in finished products, by coating the soft capsules beforehand prior to their incorporation in the material to be incorporated and incorporating the same into said material. CONSTITUTION:Soft capsules are applied with a coating up to 1.5-5 times the weight of the original capsules on their surfaces by means of, for example, sugar such as cane sugar, sorbit, grape sugar or the like, sugaralcohol, starches as well as a glue such as gum arabic. Next, the coated soft capsules are dried,  after which they are incorporated into the other raw material to be tabuleted  and the mixture is tabuleted by an ordinary method. Since the soft capsules per se are sugar-coated, they are hard to break even when the capsules directly  contact the surfaces of mortars and pestles. Even if the capsules may break and  the material filled therein flows out, the material is absorbed with the coating  material or the like, and no influences are given to the mortars and pestles,  thus long-term stable tableting is accomplished.

Title: Formation of fine pattern
Inventor: NUNOKAWA MITSUJI
IPC: H01L21/3065
Filed: 1986-08-05
Abstract: PURPOSE:To form a fine pattern without damaging a substrate by a method wherein two kinds of metal films being different in etching speed are laminated on a substrate with an interlayer insulating film interposed in between, and the metal film of the upper layer is etched selectively so as to control the thickness. CONSTITUTION:An interlayer insulating film 32 of SiO2 is formed on a GaAs substrate 31 forming an AlGaAs epitaxial layer. Next, after a titanium film 33 is formed by evaporation, a metal film 34 whose etching speed is higher than that of the film 33 is formed by evaporation. Then, a photoresist film 35 having an opening 36 is formed on the film 34. When ion milling is applied with the film 35 used as a mask and by using an Ar gas, metal ions produced by etching stick to the opening 36, and thereby the dimensions of the etched part of the film 34 are lessened. The dimensions of the opening of the film 34 are controlled by controlling the evaporation thickness of the film 34, and the films 32 and 33 are etched with the film 34 used as a mask.
