Title: Production of substrate having buried insulation film
Inventor: OKUBO YASUNORI
IPC: H01L21/304
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To produce a substrate conveniently without forming a polysilicon layer by polishing a first insulation film formed on the irregularly patterned face of a first substrate flatly and then pasting the surface of a second insulation film formed on the first insulation film and one face of a second substrate. SOLUTION: An irregular pattern of grooves (a) is formed on one face of a semiconductor substrate 11 and a first insulation film 13 is formed on the surface of the substrate 11. Surface of the first insulation film 13 is then polished up to the protrusion of the irregular pattern and a second insulation film 14 is formed on the flattened surface. Subsequently, another substrate 12 is prepared and one surface thereof is applied with the surface of the second insulation film 14 on the semiconductor substrate 11. Subsequently, the substrate 11 is chamfered and polished and the silicon film 11 is polished selectively. According to the method, filming material can be saved and production cost can be reduced by shortening the film deposition time.

Title: Induction heating system of continuous transport type
Inventor: NOGUCHI TAKUJI
IPC: H05B6/10
Filed: 1990-03-05
Abstract: PURPOSE:To prevent yielding an annealed workpiece by combining the stationary heating with transported heating in a certain specified sequence, and thereby holding a work to be heated, which will be carried out after resumption of the operation, at a certain heated level. CONSTITUTION:When failure has occurred on a heat processing line, a pinch roller 2 is stopped, and power supplies La, 4b for heating process refrain from current feed. Leaving the line to cool down will vary the thermal state from the curve 21 to one 22. When the heating is to be resumed, only the power supply 4b is operated, and the pinch roller 2 is kept at a standstill, and now only the curve 22 part in the region of a heating coil 1a will approach the curve 21. When thereafter the temp. of a work to be heated 10 is turned in the state corresponding to the curve 21 on the basis of the specified motion, the operation of the power supply 4b is resumed. The pinch roller 2 is driven, and the work 10 is fed to another coil 1b, and static heating is performed by the power supply 4b. When in approximation to the temp. rising curve 21 at the time of steady heating from the state with curve 23, transition is made into the steady operation. This constitution ensures temp. keeping of major parts to prevent yielding of an annealed work, and the operations can be performed easier.

Title: Printer
Inventor: MORI TAKASHI
IPC: B41J2/455
Filed: 1994-03-24
Abstract: PURPOSE:To obtain a printer preventing a temperature increase in the device while making especially a power source module small in size and preventing a rise in the cost of the device. CONSTITUTION:A positive characteristic thermistor 14 is provided in a power supply circuit to a driver 11 driving LED elements 12. If a large supply current I flows when the LED element 12 is driven in accordance with a video signal (VIDEO) supplied through a shift register 8, a latch circuit 9, and an AND gate 10, the thermistor 14 restricts the supply current I for driving the LED element 12 by a power source of a small capacity. Namely, when a large supply current I flows to the thermistor 14, the thermistor 14 is raised in temperature and increased in resistance value, thereby limiting the supply current I and driving the LED element 12 by a power source of a small capacity. Therefore, a power source module putting out the supply current I to an LED head can be reduced in size.

IPC: B01J33/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To make the particle size distribution narrow by suppressing sintering of ultramicro particle-like noble metal, while coagulation of the noble metal itself is restrained, and also controlling average size of deposited noble metal particles. SOLUTION: The noble metal is deposited on the first ultramicro particle-like carrier particles 1 having 1-100nm average sizes, subsequently is uniformly mixed with the second carrier particles 3 having average size equal or larger than it of the first carrier particles 1 and or equal or less than it. Noble metal salt becomes ultramicro particle-like metal by a heat treatment after the deposition, and since the first carrier particles have nearly equal size, about one piece of noble metal particles is deposited on one piece of the first carrier particles. Thus, closely approaching of the deposited noble metal particles themselves is prevented by being interposed the second carrier particles, and the sintering is restrained.

Abstract: PURPOSE:To obtain abrasive grains giving a long-life cutting blade suited for use in cutting a hard and brittle material such as a reinforced plastic by forming a film of either a nickel-based soft magnetic material or a cobalt-based hard magnetic material by plating on the surface of abrasive grains. CONSTITUTION:A film of either a soft magnetic material, e.g. nickel or a nickel alloy, or a hard magnetic material, e.g. cobalt or a cobalt alloy, is formed on the surfaces of abrasive grains by electrolytic or electroless plating to obtain magnetic abrasive grains. These grains are suspended in an electroless plating bath and a metal base is immersed in the bath. The base is then magnetized with an electromagnetic coil so that the edge of the base severs as a magnetic pole. Thus, the grains suspended in the bath are magnetically adsorbed onto the magnetized edge. The magnetically adsorbed grains are fixed to one another and to the base by electrodeposition in an electroless plating bath to produce a cutting blade. This blade is suited for use in cutting, e.g. a glass-fiber- reinforced plastics.
