Title: Lateral insulated-gate thyristor
Inventor: HOSHI YASUYUKI
IPC: H01L29/749
Filed: 1990-10-26
Abstract: PURPOSE:To reduce stationary loss and enlarge the safe operation area on turn-off by bringing the second main electrode into contact with the exposed surface of a buffer region in addition to the surface of an emitter region. CONSTITUTION:The second main electrode 12 is in contact with the exposed face of a buffer region 10 too in addition to the surface of an emitter region 11. Accordingly, the carriers, which are accumulated by conductivity modulation in a high-resistivity semiconductor layer 2 during ON-time, are drawn out to the second main electrode 12 by short-circuiting the emitter region 11, which is in contact with the second main electrode 12 separated from the first main electrode 13 on the side where an insulated gate 8 is made, with the buffer region 10 contiguous to it, or turning on the second MOSFET in which the emitter region 11 or the buffer region 10 serves as the channel region, whereby the speed of the turn-off can be increased without raising the on voltage, and also the parasitic carrier operation on turn-off can be prevented. Hereby, the safe operation area can be enlarged, and the stationary loss can be reduced.

Title: Ultrasonic measuring method of vibration at different parts of heart
Inventor: NAKABACHI NORITOSHI
IPC: A61B10/00
Filed: 1990-10-29
Abstract: PURPOSE:To measure time-series signals of vibration speeds in various parts of a heart, which serve effectively diagnosis of cardio-disorder, by sampling the vibration speed of the object to be inspected with uneven intervals of the time at which reflected wave returns for each transmission pulse, and resampling the time-series data of this vibration speed at regular intervals. CONSTITUTION:When A/D conversion is made with sampling frequency several times as great as the sine frequency of transmission pulse wave, a memory capacity of 10M pieces (=10<7>) is needed in order to continuously obtain data corresponding to one heart beat, and this is rather difficult. According to the present invention, the output signals of an orthogonal intersect detector circuit including low frequency components is A/D converted with a sampling frequency fs several hundred times as large as the repeating frequency of the transmission pulses, and digital signals xr(n), xi(n) are obtained. To make A/D conversion for one sec continuously in case fs=1 MHz, it is enough with provision of a memory capacity of 1M pieces approximately, which is practicable. Thereby vibration signals of various parts of heart in pulsation with large amplitudecan be measured with high accuracy.
