Inventor: NISHIKAWA KIICHI
IPC: H01L29/78
Filed: 1987-03-25
Abstract: PURPOSE:To obtain a field effect type semiconductor device miniaturized without deteriorating usual functions, which is able to contribute to the high density integration, by covering the side surface of a control electrode with an insulating film having a constant thickness, and further covering the upper surface and the lower surface with the insulating film. CONSTITUTION:After an oxide film 5, a nitride film 6 and an oxide film 9 are eliminated in order by an etching, an oxide film 10, a polysilicon film 11 and a nitride film 12 are formed in order on the whole surface of an exposed semiconductor substrate 1. Further, a resist 13 is formed on the nitride film 12, and subjected to patterning to form a desired width in accordance with the width of a gate electrode. By using the resist 13 subjected to patterning as a mask, the exposed nitride film 12 and polysilicon film 11 are eliminated by an anisotropic etching. After that, the polysilicon film 11 is subjected to side-etching, and the width is narrowed so as to be equal to the desired width of a control electrode.

Title: Computer capable of getting error
Inventor: IMAI TEIZO
IPC: G06F7/38
Filed: 1988-03-26
Abstract: PURPOSE:To detect the change of precision accompanied with arithmetic operations by appending data indicating the precision of real number data to this real number data. CONSTITUTION:Real number data is stored in a form of a+ or -d and has a q-bit error part besides an exponent part, a sign part, and an n-bit numerical part. An r-bit deviation part may be added. When the number of practically effective digits in the numerical part is smaller than (n), the leading part is '0' as it is and it is not left justified. Addition and subtraction are performed after exponent parts of two numbers are aligned by right digit shift. Digits are right shifted when results of addition and subtraction are left overflowed, exponent parts are aligned, or the number of effective digits is adjusted in multiplication and division. In case of multiplication, both numerical values are converted to a form of (the number of effective digits of the numerical parts) > (the number of effective digits of an error part), and thereafter, the difference between numbers of effective digits of both numerical values is reduced to one if there is this difference. In case of division, multiplication is performed after the reciprocal of a denominator is generated. Thus, the degree of reliability of an outputted numerical value is clarified and only a reliable part can be outputted.

Title: Composite therapeutic apparatus consisting of ferroelectric body and semiconductor
Inventor: ISHIGURO SABURO
IPC: A61N1/20
Filed: 1995-03-30
Abstract: PURPOSE:To eliminate the pain due to the morbid fluctuation of the skin potential by passing only the negative electricity produced in a ferroelectric body to the outer layer of the skin. CONSTITUTION:A composite therapeutic apparatus 10 is constituted by laminatedly coating the surface of a ferroelectric body 7 with a n-type semiconductor film 8 and a p-type semiconductor film 9. When the composite therapeutic apparatus 10 is applied to the portion 6 where there is a stiffness in the skin or a pain, an electric potential of (-, +, -, +, -) is induced on the surface of the ferroelectric body 7 in accordance with the variation of the outer skin potential of (+, -, +, -, +). Since a n-type semiconductor film 8 and a p-type semiconductor film 9 are laminatedly applied on the surface of the ferromagnetic body 7, minus electricity passes to the outer skin 2 through the n-p lamination layer, but plus electricity does not pass through the n-p lamination layer and does not flow to the outer skin 2. Thus, the outer skin potential S returns from plus to minus and is stabilized. When the outer skin potential S returns to minus and is stabilized, the true skin potential returns to plus by the dielectric action, and the stimulus to the nerves 5 disappears, so that pain is removed.

IPC: A01F12/10
Filed: 1994-03-18
Abstract: PURPOSE:To improve the working performance for switching from a reaping and threshing work to a hand-feeding threshing work. CONSTITUTION:A receiving guide 3 is placed above an extended part 1a of an under-type feed chain 1 to deliver the culm from a reaping side B to a threshing part A. The receiving guide 3 is made to be movable forward and a culm-feeding path 4 is formed between the tip end of the receiving guide 3 and the starting end of a pinching rail 2. The reaping part side of the receiving guide 3 is displaced upward or the receiving guide is separated upward to enable the feeding of culm for hand-feeding threshing. The gap between the fins of a swinging screen is closed according to the separating motion of the guide. The supporting member holding the receiving guide and an assorted working member are made to be movable upward by using separated parallel shafts and the supporting member and the working member are engaged with a common engaging part. The upward motion of the supporting member is inhibited with the working member by the lifting force applied to the receiving guide and the supporting member is lifted by the lifting operation of the working member.

Title: Exhaust valve
Inventor: NAKAYAMA TOSHIAKI
IPC: F16K15/14
Filed: 1989-03-27
Abstract: PURPOSE:To certainly exhaust an accumulated material and prevent the entrance of an external foreign material by disposing spherical shell parts in two stages, and providing slits extending in the direction crossing at right angles to each other on the respective spherical shell parts in such a manner that one slit is closed when the other is opened. CONSTITUTION:When an internal combustion engine is stopped, the connecting part 12 of the exhaust valve of an air cleaner is extended in the diameter D1 direction, and a bellows part 11 tries to extend in the arrowed direction A, but it is blocked by ribs 111, 112 and distorted by a force directing the arrow B. By receiving this force, the lip 132 of a slit 131 is opened, and the lip 142 of a slit 141 is closed, so that the accumulated material in a receiving part 15 is exhausted to a receiving part 16, and also no foreign material enters from the outside as the lip 142 is closed. When the internal combustion engine is operated, as the casing of the air cleaner becomes negative pressure, and the bellows 11 tries to contract, the lip 132 is closed, and the lip 142 is opened reversely to the above. Thus, the accumulated material in the receiving part 16 is exhausted to the outside, and the foreign material trying to enter from the outside is blocked by the closed lip 132.

Title: Shutter device of rooftop ventilating fan interlocking with wind vane
Inventor: KAWAI YUUZOU
IPC: F24F7/10
Filed: 1983-04-25
Abstract: PURPOSE:To prevent wind and rain water from entering indoor by a method wherein the blockading area of a ventilating hole is increased by harnessing wind force for the spreading- out of auxiliary shutters, which are slidably arranged at both sides of a main shutter, when the wind blows strongly. CONSTITUTION:When the wind blows at ordinary speed, auxiliary shutters 12 and 12 are pulled up on the upper parts at both sides of a main shutter 9 by the tensional force of tension springs 13 and consequently the ventilation is performed by blockading a ventilating hole 8 by the blockdaing area of a main shutter 9. When the wind direction changes, the main shutter 9, the position of which is fixed integral with a wind vane 5 through a shaft rod 11, changes its blockading position by being guided with rails 4 and 7 so as to perform the ventilation at maximum rate of air circulation while keeping the outdoor air from flowing back indoors. When the wind blows strongly, the pressing force, which is superior to the tensional force of the tension spring 13, is applied to each auxiliary shutter 12 due to the strong wind blowing against the flap 12' of the auxiliary shutter 12 and consequently both the auxiliary shutters 12 and 12 are pulled from both the sides of the main shutter 9 outwards, resulting in spreading the total blockading area by the area occupied by the auxiliary shutters 12 and 12 and consequently in surely keeping the strong wind from flowing back indoors.
