Filed: 1990-03-29
Abstract: PURPOSE:To easily integrate and to reduce attenuation of quantity of a light by covering a light propagating region between a light emitting diode and photodiode with a cylindrical light reflecting member. CONSTITUTION:A light emitting diode 10, a photodiode 20 formed through a light propagating region 14 covered at its periphery with an aluminum layer 13, and an npn transistor 30 are provided.

Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device, where bipolar transistors of different cut-off frequencies and withstand voltages are formed on the same semiconductor chip, and a method for manufacturing the device. SOLUTION: Bipolar transistors having intrinsic base layers 10 and 10' with differing thickness are formed on a same semiconductor substrate 1. The thicknesses of the base layers can be determined simultaneously by designing distances from a low-concentration collector layer 3, embedded in an opening of a base collector separation-insulating film 4, to device separation insulating films 7 and 7', and widths of grooves where the device separation insulating films are embedded. By this arrangement, the performance of a circuit using the bipolar transistors can be improved. Further, as diodes used for compensation for the withstand voltages can be omitted, increase in a parasitic capacity due to addition of diodes can be prevented. Thus, a circuit can operate at a high speed.

Title: Measuring method of magnetic flux distribution
Inventor: WATANABE SEIICHI
IPC: G01R33/02
Filed: 1979-07-02
Abstract: PURPOSE: To realize a high-speed measurement for the magnetic flux distribution of the test subject and then carry out the detection of the surface flaw, by flowing the scanning current to the linear electrode of the electronic tube set opposite to the test subject.  
     CONSTITUTION: When steel component P receives the DC magnetization by electromagnet M, the weak magnetic flux is caused evenly on component P. And if surface flaw (d) exists, the big magnetic flux occurs at the area of the flaw. The directions of these lines of magnetic force are fixed by the direction of the magnetic pole of magnet M. The electronic tube is then approximated to component P so that the electrode face of the electronic tube may be set opposite to the measured surface of P and also the coincidence may be obtained between the direction of the line of magnetic force and the direction of the linear electrode. As a result, the line of magnetic force passes through the electrode surface to reach up to the inside of the electronic tube. Under these conditions, the horizontal scanning is given with vertical deflection to the electron beam against linear electrode 6 or in correspondence to a certain linear electrode among electrodes 6.1W6.n. Thus the change is given to the magnetic flux distribution within the electronic tube.
