Thereafter, the implanted boron is activated through the heat processing and thereby a p<+> type external base region 35 is formed. Different masks are not required for the formation of pattern 34 and external base region 35.

Title: Eddy current type device and method for measuring rail displacement
Inventor: SHIROTA YASUSHI
IPC: G01B7/02
Filed: 1981-04-21
Abstract: PURPOSE:To detect the central position of the rail accurately in the eddy current type rail displacement measurement, by using the average of the outputs of a pair of polygonally shaped detecting coils facing opposite to the rail, and compensating the variation in the distance from the wheel tread of the rail. CONSTITUTION:Triangular coils 6 and 7 are mounted on the lower part of a measuring car running on the rails so as to face the rail 3. Since the impedance of the coil is a function of the distance between the rail and the coil, the output, which corresponds to the displacement in the gap between the tread of the rail and the coil and in the span in the right and left directions of the rails, can be detected when a high frequency current is flowed in the detecting coils. When the rectangular coils are used, the detection can be performed in the broad range with excellent linearity. The average of the output of a pair of the coils indicates said gap. Therefore, when the coil output is compensated by the difference between said average and a reference value, the accurate measurement can be performed even though said gap is varied.

Title: Waveform generation circuit and semiconductor tester
Inventor: OSAKI AKIO
IPC: G01R31/28
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a high speed waveform generation circuit. SOLUTION: When a high level is inputted, as a switching signal, to a buffer circuit B1, transistors Q2, Q3 are turned on while transistors Q1, Q4 are turned off. When a low level is inputted simultaneously, as a switching signal, to a butter circuit B2, transistors Q6, Q7 are turned off while transistors Q5, Q8 are turned on. Currents Is1, Is2 flow from a same constant current supply through the transistors Q2, Q3 to diodes D1, D2 which thereby has an identical voltage drop and the potential at an output terminal OUT is equal to an input voltage V1. When a switching signal is switched subsequently, the potential at the output terminal OUT is switched to an input voltage V2. Since a waveform generation circuit comprises a constant current source, a current switch and a diode and the additional parasitic capacitance to the output is reduced, high speed operation is realized.

Filed: 1982-04-12
Abstract: PURPOSE:To set operable condition within a short period with a heat generated from a laser tube without generation of mode hopping by sufficient forced expansion of supporting means through a heater. CONSTITUTION:A supporting rod 5 used as a supporting means is set in the forced heating condition with a heater 6 in the preceding stage where the feedback mechnism is operated for laser oscillation or stabilization. At this time, a heating temperature is set to a temperature which is further higher than the temperature to which the supporting rod 5, expanded up to a degree not allowing skip of vertical mode, reaches. Thereby, heat is not led to the supporting rod 5 from the laser tube 2 dueing laser oscillation and a thermal influence is hardly generated from the laser tube 2.

Filed: 1978-05-18
Abstract: PURPOSE: To facilitate the manufacture of the device by using the solar battery electrode and the printing method and also by drawing out the electrode via the normal Pb-Sn group solder.  
     CONSTITUTION: The Al-use solder and the ceramic-use solder are mixed and fused together to obtain the alloy composition of Pb4.7∼23.4 Sn8.2∼40.9, Sn8.1∼28.2, Cd26.7∼60.9 and Sb0.3∼1.6wt% each in terms of the adhesive performance. This solder alloy is effective to the oxide since Zn and Sb shows a high affinity. With use of this solder alloy, the lead wire can be drawn out directly, but it is recommeded to correct the solder alloy with use of the normal solder for the beauty and reinforcement of the soldered surface. With sue of such solder alloy, the lead wire can be drawn out easily from the electrode formed through the printing  method and via the normal Pb-Sn group solder. Thus, the solar battery can be obtained with high relability and good looking, and the electrode formation through the printing method becomes effective to secure an easy formation of the device featuring a high conversion efficiency.
