Title: Platinum thermo-sensitive device
Inventor: SAMEJIMA MASANORI
IPC: H01C7/04
Filed: 1990-02-27
Abstract: PURPOSE:To increase strength at terminal parts without decreases in connectedness of leads by overlaying a substrate with the platinum first film in a predetermined pattern, a terminal part with the second film of high adhesion with the substrate between the first film and the substrate, and the first and second films with the third metal film. CONSTITUTION:A substrate 1 is overlaid with the first film 2 made of platinum in a predetermined pattern, a terminal part which extracts electric signals with the second film 3 of high adhesion with the substrate between the first film 2 and the substrate 1, and the first and second films with the third metal film 4. That is, presence of the second film 3 of higher adhesion with the substrate than with the platinum film 2 at a terminal part allows increases in adhesion strength at the terminal part. Further, overlaying the platinum film 2 with the third metal film 4 allows the solution of decreases in connectedness of a lead 6 due to diffusion upon heat treatment. Use of a metal film 4 allows decreases in resistance value at a terminal part and improvement in characteristics. This process can increase strength at a terminal part of a platinum thermo-sensitive device without decreases in characteristics.

A feeler holder is constituted of a fixed block 52 and movable blocks 53, 54. The bonding face of the block 52 to the block 53 is a concave which forms an arc, and a fitting groove 55 is formed in the direction of the circumference of a circle. On the other hand, the bonding face on the side of the block 54 is a convex which forms an arc whose curvature is the same as that on the side of the block 52. A protrusion part which is engaged with the fitting groove 55 is formed. The face of the block 53 which is faced with the block 54 is a plane which is parallel with the Z-axis. Thereby, an oblique flaw can be detected without changing the impinging angle, i.e., the angle of refraction, of the title apparatus.

Title: Knocking control device for internal combustion engine
Inventor: KAWASAKI YASUSHI
IPC: F02B1/04
Filed: 1995-03-07
Abstract: PURPOSE: To properly judge the occurrence of knocking even when the maximum value on the knocking of an internal combustion engine becomes the saturation state, suppress the occurrence of knocking to the minimum, and improve the fuel consumption and output torque to the maximum. CONSTITUTION: An electronic control unit(ECU) 41 judges the presence or absence of the occurrence of knocking based on the analog value outputted from a knock sensor 36 and the judgment level and controls the ignition timing based on the judged result. The ECU 41 converts the analog value to a digital value when the prescribed time Tn elapses after the analog value crosses '0' and detects the maximum value on knocking based on the digital value. The ECU 41 corrects the judgment level based on the shape of the probability distribution on multiple maximum values, compares the digital value with the corrected judgment level, and judges the occurrence of knocking. When the detected maximum value is at the saturation state, the ECU 41 changes the prescribed time to make the maximum value relatively small.

Abstract: PURPOSE:To obtain a simplified input switching circuit by connecting two transistors which are mutually complementary between two input signal lines and ground so that emitters and collectors respectively come to opposite directions and inputting a selection signal taking the value of H or L to the bases of both transistors in common. CONSTITUTION:The collector of an PNP transistor Q1 is connected to one input terminal 14 of switching IC 10, and the emitter of an NPN transistor Q2 to the other input terminal 15.
