Title: Micro-tunnel junction superconductive transistor
Inventor: OI AKIHIKO
IPC: H01L39/22
Filed: 1994-01-12
Abstract: PURPOSE:To eliminate the inter-element difference of a bias voltage applied across a drain and source by providing a gate using a Schottky barrier in the central area of a superconducting material joined with a source area and drain area through a micro-tunnel junction. CONSTITUTION:An Si semiconductor film 5 provided with a Schottky barrier formed between the film 5 and Al is formed on a central area l and brought into contact with a gate electrode 6 connected with a gate terminal G. A source electrode 7 connected with a source terminal S and drain electrode 8 connected with a drain terminal 8 are respectively brought into contact with a source area 2 and drain area 3. Al becomes superconductive at a temperature of <=1.75 K and the electric current flowing between the source and drain electrodes 7 and 8 is controlled by a gate voltage applied across the semiconductor film 5 through a gate terminal G, because a micro-tunnel junction is formed between the central area 1 and source and drain areas 2 and 3. Therefore, any element have the same gate voltage and the inter-element difference of the bias voltage applied across the source and drain can be eliminated.

Title: Misfire detecting device of multicylinder internal combustion engine
Inventor: YAMAMOTO KENJI
IPC: F02D45/00
Filed: 1993-01-08
Abstract: PURPOSE:To provide a misfire detecting device of a multicylinder internal combustion engine which can detect a misfire accurately, to an internal combustion engine having an uneven rotation frequency of each cylinder in a normal combustion condition. CONSTITUTION:A correction coefficient K(i) for each cylinder is calculated and stored depending on the unevenness of the rotation frequency NE(i) for each cylinder calculated at every explosion stroke of each cylinder when the internal combustion engine is in an idle condition (decided as a normal combustion condition). In the normal operation of the internal combustion engine, the rotation frequency NE(i) is corrected individually to each cylinder (Step 301). When the difference between the rotation frequency NEnew after the correction of the cylinder processed this time, and the rotation frequency NEold after the correction of the cylinder processed last time exceeds a specific value A continuously for B rounds or more, (Step 309: YES), it is decided as an accidental fire (Step 315). As a result, the influence of the unevenness of the rotation frequency NE(i) for each cylinder existing at a normal combustion condition is little, and synchronous misfires of cylinders with different phase 360 deg. CA can be detected.

However, a vacuum pump 6 operates all the time and air flow shown by an arrow is generated in an area near the bearing 8 and the pulley 1. Dust is sucked forcibly to a suction nozzle 4 without floating in air due to the air flow. Therefore, it is possible to prevent dust generated from the pulley 1 and the bearing 8 from attaching to the wafer 3.

Abstract: PURPOSE: To provide a pre-treatment method of a steel hybrid circuit board for enabling the carrier substrate of the thinner steel hybrid circuit board by adjusting an inconvenient thermal stress that increases during a later calcination process prior to the application process of a covering requiring calcination. CONSTITUTION: A steel hybrid circuit board 12 is clamped by a retention device, and a group of fine particles 20 made of a metal material are sprayed on its upper surface 13 by jet injection, thus giving a mechanical pre-stress to the circuit board 12. At this time, the pre-stress is given, so that an upper surface 13 of the circuit board 12 becomes a recessed shape. A fine particle injection process continues until a controlled, desired curvature of the circuit board 12 that is subjected to pre-stress can be obtained. The degree of the desired curvature due to the pre-stress is determined according to the requirement for adjusting a deflection generated during a calculation process in a direction that is opposite to the direction of curvature due to the pre-stress of the circuit board 12.

Abstract: PURPOSE: To prevent that a connector is assembled on a base plate in leaving the fitting of both first and second connector elements being incomplete as well as in a state that both first and second lead wires are not conducted with each other intact, and further forwarding the assembly operation of an air bag module, from occurring. CONSTITUTION: A connector 1 is supported on one side of a base plate 10 by means of a pair of holding arm pieces 11. In this case, the connector 1 and these paired holding arm pieces 11 are not engaged with each other unless both first and second connector elements 3 and 5 themselves are completely fitted with each other and an overall length L1 of the connector 1 is set to be less than an interval DL between both first and second keep arm pieces 12 and 13. Accordingly, insofar as the connector 1 and these arm pieces 11 are not engaged with each other, an engaging arm 29 installed in a cover member 15 and an engaging projection formed in the second keep arm piece 13 are not engaged with each other.  In addition, barring an engagement between the engaging arm 29 and the engaging projection, a projection 31 formed in the cover member 15 interferes with the air bag module, disabling the assembly operation of this air bag module.
