Title: Manufacture of soi substrate
Inventor: SO SOBUN
IPC: H01L21/306
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To make uniform thickness of a semiconductor layer by forming an element separation film on a semiconductor surface where a polishing process is performed by using a boron ion layer. SOLUTION: One surface of a base Si layer 11 is thermally oxidized to form an embedded oxide film 12. A boron ion layer 14 is formed to a first depth from the upper surface of a semiconductor Si layer (Si layer) 13, then etching is performed to form a trench 15 to a second depth. After the base Si layer 11 and the Si layer 13 are bonded, the rear surface of the Si layer 13 is primary- polished to a trench bottom surface part. Then an etching-removal is performed until the boron ion layer 13 is exposed. The rear surface of the Si layer 13 is secondary-polished to form a semiconductor layer 13a, and an Si nitride film 16 is vapor-deposited, and etching is performed to leave only a part above the semiconductor layer 13a out.  After an Si oxide film 13 is vapor-deposited between the Si nitride film 16 and the semiconductor layer 13a, an element isolation film 17a is formed by etching with the Si nitride film 16 as a stop layer. Then, by removing the Si nitride film 16, an SOI substrate 20 is provided.

IPC: G06F15/80
Filed: 1987-07-23
Abstract: PURPOSE:To increase the communication speed for synchronous communication among processing units of the parallel computers connected adjacently to each other in an n-dimensional state, by using said processing units and a register contained in a control unit to control packet data. CONSTITUTION:When data communication control is carried out among processing units PU21-2m of the parallel computers connected adjacently to each other in the n-dimensional state, a register 3 is added to a control unit CU together with registers 31-3m set into the units PU21-2m respectively. In case the registers 31-3m defines the 2-dimensional state (X, Y) with 1st and 2nd bits, the register 3 instructs at first the X-directional transmission to the PU21-2m owing to an uncompleted state of transmission. Thus those PUs resets the 1st bit of the register and perform the Y-directional transmission. The registers 31-3m are replaced via an OR operation part 4.

The signal is used as the base band video signal or the RF video signal by an RF modulator 2 and it is fed to a television receiver being an object of inspection. Thus, the inspection personnel checks the state of the display screen in the 3-stage display by visual observation to confirm whether or not the reference horizontal synchronizing oscillation frequency is deviated thereby reducing the check time.

Title: Preparation of gelatinous seasoning
Inventor: OKUNO KAORU
IPC: A23L11/20
Filed: 1987-07-22
Abstract: PURPOSE:To prepare a seasoning having excellent suspensibility and dispersibility and improved water holding properties without deteriorating gel, by blending a seasoning, such as soy sauce or sauce, with gelan gum. CONSTITUTION:Agar, gelatin, carrageenan, etc., have been utilized for gelatinizing seasonings. Although such substances are capable of gelatinizing the seasonings, they have disadvantages in that acid resistance is absent and deterioration in gel is caused by thermal sterilization to unstabilize a dispersion and suspension state of solid or semisolid materials or dispersion or fats and oils. In order to solve the disadvantages, spices, such as soy sauces, MISOs (fermented bean paste), sauces, dressings, mustard, Japanese horseradish, garlic or Guinea pepper, are added and blended with an aqueous solution prepared by dissolving gelan gum by heating. Thereby the aimed seasoning having excellent suspensibility and dispersibility and improved water holding properties can be prepared without causing deterioration in gel.

Title: Growth method of chemical compound semiconductor crystal
Inventor: SHIMAZU MITSURU
IPC: C30B29/42
Filed: 1991-07-24
Abstract: PURPOSE:To provide an organic metal vapor growth method of forming a III-V compound semiconductor of multilayered structure, where a multilayered structure possessed of a sharp doping profile at the interface of growth layers can be easily realized. CONSTITUTION:When a compound semiconductor is doped with carbon using organic metal compound as V material, V hydride is periodically supplied at the same time. N-type doping gas is periodically supplied at the same time with the V hydride to form a doping superlattice. Furthermore, V hydride is changed in supply period, whereby carbon is controlled in doping amount. By this process, the interruption of growth and the change of growth temperature are not required to be carried out at the boundary surface of layers. Therefore, not only an operation time can be saved but also impurities or defects are hardly introduced to the boundary surface of the growth layers, so that an epitaxial layer can be enhanced in quality.
