Title: Character generating device
Inventor: FUKUDA SHINICHIRO
IPC: G06F17/21
Filed: 1991-07-04
Abstract: PURPOSE:To generate the same form of character when a family character is generated from one font data, particularly when a character in a middle weight where the existing face is present is generated. CONSTITUTION:Font data of one character is constituted with the corresponding position and attribute information of control points in thin weight and thick weight. Also the position of the control points is stored in a middle weight as required. In the middle weight where the existing face is present, original weight information comprising storing weight information for displaying whether the control points are stored or not, thickness compensation information for compensating the thickness, and position compensation information for compensating the position of controls are stored. Each of these information is stored for each unit of stroke which constitutes the character.

Title: Fabrication of semiconductor laser
Inventor: MIYANAGA RYOKO
IPC: H01S5/30
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To obtain a GaN based semiconductor laser having optical and electrical characteristics excellent in stable single transverse mode operation, low threshold level current density, or the like, with high reproducibility. SOLUTION: At first, a buffer layer 12 of GaN and an n-type contact layer 13 of n-type GaN are grown on a sapphire substrate 11 of (0001) face. A dielectric film of SiO2 is then deposited on the entire surface of the an n-type contact layer 13 followed by formation of a stripe mask pattern 25 extending in the (1-100) direction on the upper surface of n-type contact layer 13. Subsequently, a current constriction layer 14 of p-type GaN is grown in a region other than the mask pattern 25 on the upper surface of the n-type contact layer 13. In this regard, an opening 14a is made in the region of the mask pattern 25 and the wall face of the opening 14a is inclining about 60 deg. of angle β with respect to the substrate surface because of face orientation dependency of GaN growing speed.

Title: Oriented diamond film and its formation
Inventor: POORU SAUSUWAASU
IPC: C30B25/02
Filed: 1993-07-02
Abstract: PURPOSE:To form an oriented diamond film on a silicon wafer in high reliability and to enable the easy production of a diamond film having high quality. CONSTITUTION:A surface of a silicon single crystal substrate is pretreated by exposing to a carbon-containing plasma. A bias potential is applied to the pretreated surface while monitoring the completion of the nucleation on the substrate surface. The nucleation on the substrate surface for the growth of oriented diamond crystals is performed by this process. A crystalline diamond is deposited on the nucleated surface from a carbon-containing plasma to form an oriented diamond film on the silicon single crystal substrate. The crystalline diamond film formed on the silicon substrate by this process is composed of oriented columnar diamond crystals to form an essentially uniform tiled pattern. Practically, these columnar crystals have quadrilateral forms in general and both sides of the crystals are conformed to each other.

Title: Fault tolerant system, fault tolerant processing method and recording medium for fault tolerant control program
Inventor: MATSUSHITA KOZO
IPC: G06F11/20
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To easily designate a specific CPU that takes over the processing of another faulty CPU for every task in a multiprocessor system. SOLUTION: A take-over decision part 11 searches for a task which is operating with a faulty CPU from the transition information, i.e., the series of the CPU number that takes over the task included in a reconfiguration table 2 and the current transition position showing the CPU under processing in a current transition position table 4 after the CPU fault is detected and then checks the CPU that takes over the task. When the checked CPU is its own one, a standby task start part 12 starts a standby task 3 of the relevant task to take over the processing. A current transition position updating part 13 updates the current transition position of the table 4. When no CPU takes over the task, the task or a total system is discontinued according to the processing selection information.

IPC: C08G2/00
Filed: 1994-08-15
Abstract: PURPOSE: To continuously prepare homopolyoxymethylene and copolyoxymethylene having a stable terminal group in a homogenous phase.  
     CONSTITUTION: Protonic acid is caused to be present within the polymn. zone of a cylindrical reactor having a fixed stirring member as an initiator in an amt. of 0.005-500 ppm to polymerize a cyclic formaldehyde oligomer. The stagnation time of the reaction components in this zone is set to 0.1-10 min and the initiator is deactivated immediately after polymn. There is a fluid transition between the polymn. and deactivator zones which is determined solely by the addition of the deactivator and, besides deactivation, the stabilization of chain ends is carried out in the presence of the residual momers and a volatile component is removed from the reaction mixture in a subsequent gas vent unit. Stabilization is carried out in the presence of an alkaline substance at 150-250°C and, if necessary, in the presence of water or primary alcohol or at 175-250° in the absence of these additives.

Filed: 1991-07-31
Abstract: PURPOSE:To prevent a hazard, skew and racing from occurring by simulating a clock input to a register as a correct clock input when it transits from a first level, a third level to a second level or in the reverse order. CONSTITUTION:A '0' level is defined as the first level, a '1' level as the second level and an 'X' level as the third level. In a normal operation, since a clock input C changes '0' 'X' '1' and an input D is '1', an output Q changes 'X' 'X' '1' because the initial value of a register 10 is indefinite. When the input D changes '1' 'X' '0' and when the clock input C changes '1' 'X' '0' and then changes '0' 'X' '1', the output Q changes '1' 'X' '0'.
