Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To improve leak diagnosis accuracy of a vapor fuel treatment device. SOLUTION: In this device, driving current of an electrically driven pump 28 is sensed when air is circulated through a first passage 25 on which a reference orifice 24 is arranged, and determination level is set.

Title: Speed change controller for automatic transmission
Inventor: TAZAWA MITSUGI
IPC: F16H61/08
Filed: 1993-06-18
Abstract: PURPOSE:To precisely detect the speed-change start timing by causing the time passage data after issuance of a speed-change instruction and the number-of- rotation data concerning the number of rotations of an input shaft of the automatic transmission to be processed in a neural network per se by performance of the weighting obtained by learning performed in this neural network. CONSTITUTION:When speed change has been done by engagement/disengagement of a friction fastening means (a) of an automatic transmission (b) through supply/discharge of pressure oil with respect thereto, the time passage from the outputting of a speed change instruction is measured by a time-length measuring means (j) of a control unit (d). Further, the rate of change in the number of rotations detected by a detection means (g) which has relevancy to the number of rotations of an input shaft of the automatic transmission (b) is calculated by a change-rate calculation means (k). Then, the time passage and the change rate are inputted to a neural network (m) and specified weighting is performed thereon in accordance with the between-neuro-element coupling weight. Thereafter, when a total sum of the respective weighted values exceeds a specified threshold value, a speed-change start signal is outputted. By this signal, a hydraulic actuator (h) is controlled to an oil pressure for the speed-change time only.

Title: Magnetic head adhering jig
Inventor: MASUBUCHI YOICHI
IPC: G11B5/127
Filed: 1988-06-14
Abstract: PURPOSE:To set the load applied to a block via the external pressing force by pressing a slider to the core block half bodies and fixing the slider to a jig main body by means of a prescribed clamp screw. CONSTITUTION:The adhesive is applied to the magnetic head core block half bodies 3 and these bodies 3 are set between an adhering jig main body 1 and a slider 2. Then the slider 2 is pressed to the bodies 3 and a clump screw 8 piercing through a through hole of the slider 2 is screwed inside. Thus the slider 2 is fixed to the main body 1. These body 1 and the slider 2 are heated up and cooled so that the adhesive like glass, etc., is hardened. Thus a magnetic core block is finished. Therefore the pressing force applied to the bodies 3 can be set with the external pressing force not with the conventional torque produced by a screw. As a result, the reproducibility is improved and at the same time the variance of the gap length is reduced.

Abstract: PURPOSE:To eliminate the unevenness of gate-trigger currents by a simple structure by forming the fifth n layer of which the fourth n layer is extended under a gate electrode. CONSTITUTION:A p2 layer between an n2 layer 4 and an n4 layer 6 is surrounded, the n4 layer is extended so as to contact with an end section of a gate electrode 7, and the fifth n layer (n5) 10 is formed. Thus, gate currents A flowing through the p2 layer just under the n2 layer are utilized for the ignition of an SCR of p1-n1-p2-n5. According to this constitution, gate-trigger currents in the case when gate electrode potential is negative and the second main electrode potential is positive can be reduced as compared to the case when only gate currents flowing through the p2 layer just under the n4 layer contribute to the ignition of the first SCR as seen in conventional triacs. Trigger currents are also uniformalized.
