Title: Optical recording medium and optical recording method
Inventor: MOCHIZUKI HIDEAKI
IPC: G11B7/246
Filed: 1987-12-08
Abstract: PURPOSE:To enhance the flexibility of software production and to reduce the cost at the time of small-quantity production by forming the title medium in such a manner that the change in the optical properties formed on an optical recording layer is maintained even after the treatment for making the recording layer transparent prior to reproduction. CONSTITUTION:This optical recording medium is constituted by providing the optical recording layer 2 on a transparent substrate 1 and further providing a reflecting layer 3 thereon. The optical recording layer 2 is recorded with signals as the change in the optical properties by irradiation of laser light to be used for recording. The medium is so constituted that the recording part maintains the change in the optical properties with the laser light even after the treatment for making the recording layer 2 transparent. Since the change in the optical properties generated at the time of recording is maintained even after the recording layer 2 is made transparent, the signals can be recorded as the difference in the quantity of the reflected light between the signal recording part and the unrecording part at the time of irradiation of the reproducing light after the recording layer is made transparent. The need for the process for producing a costly stamper in the manufacture of CDs is thereby eliminated and the small- quantity production of the CDs and CD-ROMs of the same software is executed at the low cost with ease.

Title: Semiconductor integrated circuit
Inventor: HISAMUNE YOSHIAKI
IPC: H01L21/8247
Filed: 1989-11-28
Abstract: PURPOSE:To prevent a silicon substrate from being short-circuited to an interconnection or the like which is formed during a transfer to a next process even when a second-layer insulator used to fill up a groove region surrounded by a first-layer insulator is overteched by a method wherein the first-layer insulator formed on an inner wall of a groove made in an element isolation region of a semiconductor substrate forms a sidewall. CONSTITUTION:Grooves 2 are made in an element isolation region of a P-type silicon substrate 1; inner walls of the grooves 2 are oxidized; after that, an oxide film 7 and a phosphate glass (BPSG) film 8 containing boron are formed one after another; the BPSG film 8 is made to reflow by a heat treatment; the grooves 2 are filled up completely. The BPSG film 8 and the oxide film 7 are etched back one after another by a dry etching operation by using CHF3 gas; an active region of the substrate 1 is exposed. At this etching-back operation, an etch rate of the oxide film 7 is smaller than an etch rate of the BPSG film 8; the oxide film is left as sidewalls 9 in the groove parts in the silicon substrate after the etchingback operation. Thereby, it is possible to prevent that a gate electrode interconnection formed in the next or later process is short-circuited to the substrate 1.

IPC: C25D13/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a method of sealing treatment for a sprayed deposit, capable of hermetically sealing, with certainty, pores in a sprayed deposit formed on the surface of a member made of metal, and a member made of metal to which this sealing treatment is applied. SOLUTION: Cleaning treatment for a metallic sprayed deposit is first performed by successively applying degreasing, washing in water, draining, drying, or the like, to a member after the formation of a metallic sprayed deposit, and then the member after the treatment is immersed in an electrodeposition cell in which a solution containing electrodeposition coating material is held. As the electrodeposition coating material, either of cationic one and anionic one can be used. For example, in the case where the electrodeposition coating material is of a cationic type, the member immersed in the electrodeposition cell is connected to a cathode, and a plate connected to an anode is disposed in a manner to be opposed to the above member, and a DC current is allowed to flow between both electrodes.  The positively charged electrodeposition coating material corpuscles are subjected to electrophoresis through the solution toward the metallic sprayed deposit on the surface of the member serving as a cathode, infiltrated into pores in the metallic sprayed deposit, and brought into contact with the inner wall of the pores, where they are deposited and made insoluble. Further, a part of the electrodeposition coating material corpuscles are brought into contact with the surface of the metallic sprayed deposit, where they are deposited and made isoluble.

Filed: 1987-12-09
Abstract: PURPOSE:To obtain a flat surface whose surface roughness is minimized allowing a grinding stone to keep sharpness by alternately laying thin super abrasive grain grinding stone plates and thin thermosetting resin plates. CONSTITUTION:A grinding stone for super finish is constituted in such a way that thin grinding stone plates 1 made of super abrasive grains and thin resin plates 2 made of thermosetting resin are layered alternately in sandwich-like state in a plurality of layers.

Title: Supervisory and controlling system
Inventor: TAKEUCHI YUTAKA
IPC: H04Q9/00
Filed: 1989-11-30
Abstract: PURPOSE:To improve the throughput of monitor item information with heavy weight by transmitting only the monitor item information equipped with the weight more than the weight designated by communication line control signal data to a host station when each slave station receives the data from the host station. CONSTITUTION:A data processing part 34 of a slave station 21 stores the communication line control signal data, which are received by a communication control part 31, to a weight decision storage part 36. Afterwards, each time the monitor item information adding the weight are applied from a monitor item input part 37, the data processing part 34 compares the weight designated by the communication line control signal data with the weight added to the monitor item information. When the latter weight is more than the former weight, the monitor item information are transmitted through the communication control part 31 to the host station. Reversely to the above mentioned case, when the later weight is less than the former weight, the monitor item information are accumulated in a data accumulation part 35. Therefore, possibility is reduced for the monitor item information with the heavy weight to be generated just while executing the processing of the monitor item information with the light weight.
