Title: Needle type probing device
Inventor: YOSHIHARA KUNIO
IPC: H01L21/66
Filed: 1985-06-21
Abstract: PURPOSE:To reduce the leak of the detection current of a metallic needle by giving a coaxial structure to a probe electrode. CONSTITUTION:A metallic needle 11 is coated with an insulating layer 12 except both end parts, and this insulating layer 12 is coated with a conductor layer 13 to form a probe electrode 10. The probe electrode has the coaxial structure with the metallic needle 11 as the center conductor and the conductor layer 13 as the external conductor. This probe electrode 10 is arranged on one principal surface of a printed board 20, and the conductor layer 13 and the metallic needle 11 are connected to a guard electrode 23 and a lead-out electrode 25 respectively. By this structure, the conductor layer 13 of the probe electrode 10 is connected to the guard electrode 23, and the potential of the conductor layer 13 is approximately equal to that of the metallic needle 11, and a current is hardly leaked between the metallic needle 11 and the conductor layer 13 therefore. Thus, the leak of the detection current due to an adhesive 21 can be ignored, and plural probe electrodes 10 can be attached closely.

The hot rolled sheet is subjected to cold rolling for one time or two or more times including process annealing into final sheet thickness and is thereafter subjected to decarburization annealing. At this time, in the first halt of the decarburization annealing, only decarburization is executed until the average grain size of primary recrystallized grains reaches at least 15mum, and, after that, decarburization and nitrification are parallelly executed. This parallel treatment is executed preferably at 700 to 900 deg.C in the atmosphere of which a mixed gas of N2 and H2 of PH2O/PH2 >=0.15 is mixed with NH3. The steel sheet is coated with an annealing release agent and is subjected to finish annealing. In this way, the grain-oriented silicon steel sheet having excellent magnetic characteristics and film characteristics can be obtd. with industrial stability.

As vehicle speed is being raised gradually, a speed-sensitive centrifugal clutch 28 is engaged so that engagement of the second speed at high speed side is realized, i.e., engagement according to predetermined vehicle speed but irrelative to engine speed is realized. Then a speed-sensitive centrifugal clutch 26 comes in and engine speed is raised gradually until the input gear wheel rotates at the rotating speed of the engine so that the third speed at high speed side is realized.  In the meantime, the engine speed is once again lower. It is being accelerated with less throttle opening until it reaches the maximum vehicle speed.
