Title: Manufacture of dielectric isolation substrate
Inventor: MIZOGUCHI TETSURO
IPC: H01L21/76
Filed: 1987-02-18
Abstract: PURPOSE:To make it possible to manufacture a substrate, which has a small curve and an insulating layer having a thickness of 1 mum or more, by adding a step, in which epitaxial growing and oxygen-ion implantation are repeated by specified times. CONSTITUTION:After oxygen ions 4 are implanted one time, a single crystal Si layer is epitaxially grown 6 utmost about 0.8 mum. Ion implantation is added in order to increase the thickness of an insulating layer and a region is formed. When ions are further implanted, the thickness of a newly formed ion implanted layer 5 is added to the thickness of the ion implanted layer 5, which has been formed before, and the thickness of the insulating layer is increased. In a curve decreasing method for forming the insulating layer by the conventional implantation of the oxygen ions 4, the thickness of the insulating layer can be increased by a desired amount. Therefore the amount of the curve can be decreased, with the thickness of the insulating film being kept, in comparison with a substrate made by a conventional manufacturing method.

IPC: B21B38/10
Filed: 1981-03-09
Abstract: PURPOSE:To reduce the manpower required for exchanging and grinding of rolls and to improve a fundamental unit of rolling, by correcting a roll gap considering an abrasion quantity of vertical rolls obtained by measuring it with- out dismounting the rolls and continuing the rolling as it is. CONSTITUTION:In universal mill rolling that web 2 and flange 3 of H shape- steel are rolled by horizontal rolls 1 and vertical rolls 4 respectively, abrasion to the depth (d), spreading over the width of flange 3, occurs in the roll surfaces of the vertical rolls 4 after the rolls are used. An Al rod, having sectional dia. larger than (d), is inserted into between the roll surface of the roll 4 and the side end-surface of the roll 1 to measure the depth of (d), and then the thickness of crushed Al rod is measured to obtain the (d) by making the upper and lower edge parts 5 and 6 of the roll 4 into contact with the side end-surface of the roll 1. Thus the roll gap of the roll 4 is compensated by (d) to treat H shape-steel having the width of flange 3 narrower than that of preceding one at the following rolling.

IPC: G06F9/46
Filed: 1989-02-14
Abstract: PURPOSE:To prevent the fault of a computer system from being erroneously detected due to the overload state of the computer system by combining the detection of task switching and the detection of a lowest/higher priority task operation and detecting the wrong task which continues execution while holding CPU resources. CONSTITUTION:A task switching notifying means 1 sets a task switching flag 31 in a fault supervising task T1 in synchronization with the task switching other than the switching from the fault supervising task T1 to the other task and the switching from the other task to the fault supervising task T1. When the fault supervising task T1 is activated at a time interval set beforehand, a fault detecting means 3 first checks a task switching flag 31 and a lowest/ highest priority task operating flag 32, when neither is st, the means 3 decides that one task continues the execution while holding the CPU resources in a wrong way.

Title: Solid-state image pickup element and white balance adjustment device using the same
Inventor: MIZOGUCHI YUJI
IPC: H01L27/146
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To automatically adjust white balance without causing a cost increase by providing a white filter passing only a white light to the surface of an ineffective area where a video signal is not used as a reproduced video image. SOLUTION: A video camera or a still camera that employs a solid-state image pickup element 10 to photograph an image uses a video signal generated from a valid area 12 as a reproduction signal of the photographed video image. On the other hand, an invalid area 14 is a margin area with respect to the valid area 12 and the physical configuration and operation are the same as those of the valid area 12, but a video signal from the invalid area 14 is not used for a reproduction signal of the photographed image. That is, since the solid-state image pickup element 10 has the invalid area 14 to a certain degree at its surrounding part, a white filter 16 can be provided on a part of the invalid area 14. Thus, a video signal corresponding to the white light passing through the white filter 16 is generated from the invalid area 14 at a bottom where the white filter 16 is provided.

Title: Biodegradable composite material and manufacture thereof
Inventor: KAYANO MINORU
IPC: B32B27/36
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To realize a composite material, which has functions excellent in water resistance, strength or the like and develops a small heating value of combustion at burningly incineration and has a property being degraded by the microbes in the earth, by a method wherein a thin flat plate made of aliphatic polyester resin is thermally fused onto at least one side of a corrugated panel made of aliphatic polyester resin. SOLUTION: This biodegradable composite material 17 is produced by fusing a thin flat plate 5 made of aliphatic polyester resin onto at least one side of a corrugated panel made of aliphatic polyester resin. The corrugated panel is produced by melting aliphatic polyester resin in an extruder and extruding it into a sheet through a die and immediately pinching it between corrugated rolls 3 and 4. Since the temperature of the resin sheet lowers below its melting temperature at its pinching, the apex parts of the corrugated panel under the state being held on the corrugated roll 4 are heated and melted with a heating device 7. The thin plate 5 of aliphatic polyester resin sheet or film just after being extruded from an extruder is piled up onto and pressed against the apex parts of this melted corrugated panel with a pressure roll 6 so as to be thermally fused together.

Title: Honeycomb type heat pipe
Inventor: NISHIO SHINJI
IPC: F28D15/00
Filed: 1979-03-24
Abstract: PURPOSE: To raise efficiency of heat transfer, by constituting a heat pipe by superposing a plurality of blocks consisting of a honeycomb-shaped unit layer having partitions in one direction and a honeycomb-shaped unit layer having partitions formed on the main surface of the former honeycomb-shaped unit layer to extend perpendicularly to the same.  
     CONSTITUTION: A honeycomb-shaped unit layer constituting a heat pipe is divided into right and left sections. Here, if the left sections of the unit layer is immersed in high-temperature, dilute sulfuric acid whereas the right section is exposed in the atmosphere, the high-temperature dilute sulfuric acid is passed through a second unit layer 2 and heat possessed thereby is transmitted to a first unit layer 1, so thatwork fluid sealed in the first unit layer 1 is evaporated. Then, vapor thus produced is carried to the right of the first unit layer 1 exposed to the atmosphere, where it is cooled and condensed, thus releasing latent heat produced at the time of condensation to the atmosphere. Therefore, it results that heat possessed by the dilute sulfuric acid is given to the atmosphere. On the other hand, since wick in the first unit layer is stuck also to the surface of corrugated thin plate 6 in the unit layer, the passage for recirculating work fluid can be enalarged considerably. Further, the corrugated plate serves to reinforce the first unit layer and also serves as medium for heat transmission in the first unit layer.
