Filed: 1990-03-20
Abstract: PURPOSE:To enable the mask misalignment to be detected as the electrical characteristic values thereby making the accurate overlapping inspection feasible by a method wherein a channel capable of continuously changing its width from a source to a drain is provided. CONSTITUTION:Within the title transistor 40 for inspecting mask misalignment wherein the patterns of a source 30 and a drain 31 as well as the pattern of a gate electrode 33 are respectively assembled into an aligned pattern and an aligning pattern, a channel 32 is formed is an isoceles triangle shape having a basic angle of theta wherein the drain 31 and the source 30 are arranged respec tively in the base side and the vertex side of this isoceles triangle. Besides, the gate electrode 33 in specific width and in parallel with the base of said isoceles triangle is formed as if overlapping with the channel 32 in said isoceles triangle shape. Through these procedures, the mask misalignment can be detected as the variable level of current value ID thereby enabling the reading- out precision to be quantified with high precision.

Title: Window glass device for elevator
Inventor: NORIMURA KENGO
IPC: E06B9/24
Filed: 1988-03-28
Abstract: PURPOSE:To prevent a crime by forming the window glass of an elevator with a glass the transparency of which can be electrically varied and electrically interlocking the glass with the operation mode of a riding cage to vary the transparency of the window glass. CONSTITUTION:An instantaneous light adjusting glass 1 is formed by interposing a liquid crystal sheet 3 between two transparent conductive films 2 and, further by interposing these between two glasses 4, 4. When a voltage is applied to this, liquid crystal molecules 5 are arranged in a defined direction causing the glass to be transparent while, as the voltage is removed, the glass becomes opaque. This glass is fitted in as the window glass 8 of a riding cage 6 and the window glass of a riding place door. As a rider performs call registration on a first floor riding place, the (a) contact 1F-a of a call registration relay is closed and, due to the arrival of the riding cage, a riding cage side alighting detecting contact 13 and the (a) contact B1-a of each floor alighting detecting relay are closed, forming a riding cage window glass driving relay circuit, to make the window glass 8 of the riding cage transparent. At the same time, the driving relay of the riding place window glass is operated to make the glass transparent. Hence, when the riding cage arrives, the glasses become transparent.

Title: Peristaltic pump
Inventor: OKADA SHIGERU
IPC: A61M1/00
Filed: 1990-03-23
Abstract: PURPOSE:To surely absorb an extra amount of crushing forces exerted by a finger under the action of excessive crushing forces by providing a pressing member which permits movement of a door in its opening direction when the amount of pushing forces exerted on a wear plate via a tube by the finger exceeds that of pressing forces. CONSTITUTION:When either one 26 of a group 26A of fingers tends to crush a tube 18 in excess, the excessive elastic reaction of the tube 18 pushes a door 13 back in the direction in which the door 13 is separated from the finger 26, against the pressing force of a pressing member. Thereby a wear plate 23 fixed to the door 13 is allowed to escape in the direction in which as the door 13 moves the plate 23 is separated from the finger 26 i.e., in the direction opposite to that in which the tube 18 is crushed, thus absorbing an extra amount of crushing forces exerted by the finger. Because the wear plate 23 is fixed to the door 13 in such a manner as being opened and closed while being stably supported by housing main body 11, the wear plate 23 is permitted to escape while maintaining its stable position together with the door 13 against the excessive pushing action of the finger 26.

Title: Keyboard ineffective input blocking system
Inventor: UEDA TOORU
IPC: G06F3/02
Filed: 1983-04-25
Abstract: PURPOSE:To decrease the ineffective load of a processor by transmitting an operating signal to a processor only when a key satisfying a prescribed order is operated from an operating device. CONSTITUTION:When the key 13 setting the initial state is operated, an address generating circuit 6 converts a received reset signal (r) into a corresponding address and transmits it to an ROM7. The ROM7 transmits a gate signal stored in the transmitted address to a register 10. The signal (r) inputs a set signal to the register 10 via a timing circuit 9 so as to store the transmitted signal from the ROM7. A register 12 stores the signal transferred from the register 10 and makes gates 5-1-5-n corresponding to keys 2-1-2-n conductive based on the predetermined operating order. Thus, the key operation not satisfying the order of operation is not transmitted to the processor 4.
