Title: Manufacture of bipolar semiconductor device
Inventor: MUTO SHUNICHI
IPC: H01L29/72
Filed: 1986-03-03
Abstract: PURPOSE:To form with high reproducibily a base electrode possessing an excellent ohmic contact, by interrupting the growth of a base layer halfway, forming selectively a mask, and forming, after the growth is ended, a base electrode on the base layer surface covered by the mask. CONSTITUTION:A base layer 4 is groven while doping is performed. While interrupting the growth, a mask of SiO2 film is selectively formed on the surface. As to the surface of an exposed base layer, the growth of a base layer 5 is ended by the same procedure. After that, a base electrode 10 is formed on the surface which is formed at the time of interrupting the growth. Thereby a base electrode 10 can be formed with high reproducibily. This electrode exhibits an excellent ohmic contact with a very thin base layer of low sheet resistance, without destructing a collector layer 3. Consequently, the bipolar semiconductor device of this invention is available for high speed operation, because the base resistance can be suppressed low.

Title: Transmitter for detection data for state of elevator
Inventor: YAMAZAKI HIROSHI
IPC: H04M11/00
Filed: 1994-03-15
Abstract: PURPOSE:To easily and quickly confirm an elevator requiring maintenace by changing a tone signal sent at the reception of a call from a tone signal in the normal operation. CONSTITUTION:When an elevator detects an earthquake, the elevator stops automatically. When the seismic intensity is smaller than a specified intensity, the elevator is restored automatically after a prescribed time and contacts 1a-1n are not closed. When the seismic intensity is higher than a specified intensity, the elevator remaines stopped and the contacts 1a-1n are closed depending on a state of a fault. A fault detection means 2a detects the closing state of the contacts and informs it to a CPU 2b. When a telephone set 5 makes a call to a remote monitor terminal 2, a terminal 2 sends a tone signal after the arrival of a call and since the CPU 2b detects a fault in the elevator and a message signal generating section 2c commands generation of a message signal, a continuous tone signal from the tone signal generating section 2d is synthesized and modulated by a gate circuit 2f. As a result, an intermittent tone signal is sent to the telephone set.

Abstract: PROBLEM TO BE SOLVED: To provide a twist angle, cell gap and azimuth anchoring measuring equipment, measuring method and a memory medium storing a program in which the in-plane distribution of liquid crystal cell characteristics can be measured without increasing the size of the equipment. SOLUTION: A light source 1, a polarizer 2, a liquid crystal cell 3, an analyzer 4, and a light receiver 5 constitute an optical element wherein the intensity of transmitting light measured by the light receiver 5 is converted through a current/voltage conversion circuit 8 into a voltage being measured by a voltmeter 9. Rotation is controlled by stepping motors 11, 12 for driving the polarizer 2 and the analyzer 4 based on the measured voltage. Furthermore, a stepping motor for moving the liquid crystal cell 3 in the plane perpendicular to the light from the light source 1 is controlled by means of a PC(personal computer) 10.  Although the size of the liquid crystal cell is increasing in recent years, the twist angle, cell gap and azimuth anchoring measuring equipment can be reduced in size by making the optical element rotatable and the in-plane distribution of liquid crystal cell can be measured.
