Title: Method for liquid phase epitaxy
Inventor: IGATA OSAMU
IPC: C30B19/00
Filed: 1987-03-20
Abstract: PURPOSE:To grow an epitaxial film having an excellent thickness distribution by dipping a crystal substrate placed in a multi-holder while rotating the holder to carry out liq. phase epitaxy, and pulling up the crystal substrate under specified conditions. CONSTITUTION:The epitaxial material is charged in a crucible 1, and inserted into a furnace core tube 3. The material is heated by a heater 4 to obtain a melt 5. The crystal substrates 6 are then placed in the multi-holder 9, and dipped into the melt 5 while rotating the holder 9. The holder 9 is rotated at about 35-90r.p.m. for a specified time, the direction of rotation is then changed, and the epitaxial film is grown to about 0.9mu thickness. When the crystal substrate 6 is pulled up from the melt 5 after the growth of film, the rotational speed of the multi-holder 9 is diminished to zero, and the lifting speed is controlled to 30-300mm/min. By this method, an epitaxial film with <=about 0.01mu standard deviation of the film thickness distribution can be grown.

Title: Liquid crystal display device
Inventor: USHIKI TAKEYOSHI
IPC: G02F1/1368
Filed: 1995-03-23
Abstract: PURPOSE:To prevent dynamic rainlike domain from degrading display grade by executing an orientation treatment in such a manner that at least one direc tion of source lines or gate lines and directors of liquid crystal molecules are paralleled. CONSTITUTION:The liquid crystal molecules 20 are oriented in parallel with a longitudinal direction where source lines run in the orientation direction of a TFT substrate and the liquid crystal molecules 20. Electric lines of force intersect nearly orthogonally with the direction of the directors of the liquid crystal molecules 20. The electric lines of force, therefore, tend to act on a twist angle so as to change this angle. As regards the tilt angle, the direction of the electric lines of force and the axial direction of the tilt angle are nearly aligned and, therefore, a drastic change is not applied thereon. Namely, the reversing of the tilt angle is prevented and the generation of the dynamic drain- like domains is suppressed. Consequently, the degradation in the display quality is prevented.

Title: Manufacture of semiconductor device
Inventor: TAKASU HIROAKI
IPC: H01L21/265
Filed: 1990-03-15
Abstract: PURPOSE:To specify the impurity concentration in a semiconductor element formation layer all over the substrate surface by a method wherein impurities is ion-implanted so that the impurity concentration peak may reach in an insulating layer. CONSTITUTION:A semiconductor substrate in a structure having a semiconductor element formation layer 1 on a holding substrate 3 through the intermediary of an insulating layer 2 is formed. Next, the element formation layer 1 is implanted with impurities by ion implantation process. At this time, the ion- implantation process is performed so that the impurity concentration peak may reach in the insulating layer 2. Accordingly, even if the film thickness of the element formation layer 1 is dispersed in the substrate 3, a semiconductor device restricting the dispersion in the impurity concentration to small amount can be manufactured. Through these procedures, the impurity concentration in the semiconductor element formation layer can be specified all over the substrate surface thereby enabling the even characteristics in case an element is formed to be exhibited.

Title: Method for injection compression molding of thermoplastic resin molding
Inventor: AZUMA NAOKI
IPC: B29K23/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To solve a problem such as flatness, a shrink, a strain or a crack by fully filling a cavity with gas at a specific pressure, injecting a thermoplastic resin obtained by dissolving a specific value of carbon dioxide, starting compressing of a mold, fully filling the cavity with a resin, continuing the compressing, cooling and solidifying the resin. SOLUTION: A pressure of gas of a mold cavity is preferably 1 to 6 MPa. This means that a carbon dioxide absorbed to a thermoplastic resin may be larger than a pressure for foaming from a flow front. The carbon dioxide dissolved in the resin is preferably 0.3 to 2 wt.%. A vent hole 17 communicating with an exterior of the mold is opened at an outside of a movable side dowel 14, a gas tube 19 is attached to its outside, a carbon dioxide gas cylinder 20 is mounted at its end, and fully filled with the gas. A pressure release valve between the hole 17 and the tube 19 is set so as to release the pressure at 3 MPa or above, thereby preventing rising of the pressure in the cavity by the injected resin.

Title: Radiographic picture reading method and its device
Inventor: TSUCHINO HISANORI
IPC: G03B42/02
Filed: 1990-03-15
Abstract: PURPOSE:To simplify the management and practical use of necessary radiographic picture information by deciding plural read-out sections on a radiographic picture converting panel in advance, and exciting and scanning the maximum read-out section included in a radiographic picture information recording region decided corresponding to a radiation irradiating region. CONSTITUTION:Plural read-out section S are decided on the radiographic picture converting panel P in advance, and the minimum read-out section S3 out of the read-out sections including the radiographic picture information recording region decided corresponding to the radiation irradiating region is excitingly scanned with stimulating light. The read-out section is a region where an electric signal obtained by the optical scanning of the stimulating light is selected as the radiographic picture information. Thus, since reading out is not required up to an unnecessary part, the reading out time of the radiographic picture converting panel is shortened. Since an obtained picture size is a size decided by a system regardless of the size of the radiographic picture information recording region, the management of a picture is simplified. Besides, the selection of plural set read-out sections is automatically carried out, so that the complication of working is reduced.

IPC: A61B6/03
Filed: 1985-03-28
Abstract: PURPOSE:To prevent a ring artifact in a picture by obtaining each deviation of each detector by means of arithmetic interpolation to correct erroneous data. CONSTITUTION:The titled X-ray CT scanner consists of an X-ray tube 1 and a detector array 2, and a member having a large X-ray absorption coefficient, e.g., an iron pin 3 is arranged between opposed positions of them. Then X rays are irradiated on the iron pin 3, the projected data of the pin 3 is collected at each element of the detector array to obtain a position thetai where the gravity center of the projected data shares at each element. Then the gravity center value alphai and a known position thetai' when no deviation exists between the detectors are made correspond to calculate the deviation DELTAthetai and the result is registered. Thus, when the projected data of an object is obtained, the correction value is calculated by the arithmetic interpolation depending on the deviation DELTAthetai of each channel.
