Title: Static induction thyristor
Inventor: HAYAZAKI YOSHIKI
IPC: H01L29/80
Filed: 1988-10-25
Abstract: PURPOSE:To obtain a static induction thyristor which can be shortened in a turn-OFF accumulation time without increasing a gate-off voltage by a method wherein a cathode region is constituted in such a state that it is made low in impurity concentration and large in resistivity. CONSTITUTION:A static induction thyristor is composed of the following, where the impurity concentration of a cathode region 3 is appropriately set so as to make the total resistance of a cathode section equal to 0.3OMEGA: a low impurity concentration N-type (N<->) base region 1; a high impurity concentration N-type (N<+>) cathode region 2 and a high impurity concentration P-type (P<+>) gate region 3 which are formed on the surface separate from each other by a specified space; and a high impurity concentration P-type (P<+>) anode region 4 provided adjacent to the rear side of the base region 1. And, a turn-OFF accumulation time can be shortened by increasing the cathode region 2 in resistivity even if the thyristor is driven by the same gate-off trigger voltage. Therefore, a static induction thyristor capable of executing a high speed turn-OFF can be obtained.

Title: Switching regulator
Inventor: WATABE SOICHI
IPC: H02M3/28
Filed: 1991-10-17
Abstract: PURPOSE:To obtain a switching regulator having a protecting circuit which had excellent protecting function against an overcurrent, an overvoltage, an overheat, etc., irrespective of a load resistance, i.e., a strong foldback drooping of protecting circuit characteristics. CONSTITUTION:When an overcurrent flows to a load L1, a current detecting transistor 30 is turned ON. A current flowing to the transistor 30 flows to a gate of a thyristor 31 to turn ON the thyristor 30, and a feedback current IF forcibly flows to a light emitting diode 23a. As a bias voltage of the thyristor 31, a negative voltage generated in a secondary coil 4 when a switching transistor 11 is turned ON is employed. The negative voltage is always held at a predetermined voltage value at a ratio in which the transistor 11 is ON or for a time in which the transistor 11 is turned ON irrespective of a magnitude of a load L2. Accordingly, since a protecting circuit 36 has foldback drooping characteristics, power supply to a secondary side of a switching regulator is abruptly decreased.

Title: Screen printer
Inventor: WACHI AKIHIKO
IPC: H05K3/34
Filed: 1990-10-08
Abstract: PURPOSE:To feed paste automatically by providing ultrasonic transmitter and receiver for measuring the profile of the paste. CONSTITUTION:When a paste 7 is placed on a screen 3 and a squeegee 5 lowers to initiate rightward movement of a print head 4, an ultrasonic transmitter 10 mounted on the print head 4 transmits an ultrasonic wave which is then reflected and received by a receiver 11. Thus received ultrasonic wave is delivered to a main controller which analyzes the ultrasonic wave to recognize the profile of the paste thus detecting the amount of paste to be used in the printing. When the squeegee 5 lifts upon finish of printing operation, the amount of paste is detected again. The amount of paste is detected similarly when the squeegee 6 lowers to initiate leftward printing operation. In other words, the amount of paste is detected during printing operation and after printing operation while sustaining continuous printing operation, and when thus detected amount of paste reaches a preset residual amount, the main controller decides that the paste must be supplemented and the main controller interrupts the operation of printer, provides a supplement command to a paste feeder 12 and resumes printing operation after confirming supplement of paste. According to the constitution, residual amount of paste is detected automatically and the paste is supplemented automatically with good timing.

Title: In situ observing method for crystal growth of multilayer film
Inventor: YOSHIKAWA AKIHIKO
IPC: G01N21/41
Filed: 1992-09-15
Abstract: PURPOSE:To make possible the spot observation of a heteroepitaxial growth by a method wherein energy light capable of penetrating from the surface of a grown crystal thin film to the interface of the heterojunction of the layer under the grown crystal thin film is used as a probe beam and the reflectivity of the interference lights of reflected light, which is generated from the surface of the grown crystal thin film, and reflected light, which is generated from the interface of the heterojunction, is detected. CONSTITUTION:An epitaxially grown layer 12 is grown on the upper surface of a semiconductor substrate 11 using a crystal different from that of this substrate 11. Here, when a probe beam 13 is made to incide in the substrate 11, reflected lights are generated not only from the surface 12b of a grown crystal surface superthin film 12a but also from the interface 14 of a heterojunction. Accordingly, lights which are detected as reflected lights of the probe beam 13 are interference lights 15 of these reflected lights. The interference light capable of obtaining a large coherent effect is the reflected light from the interface 14. Thereby, a change in the intensity (reflectivity) of the interference reflected light from the surface 12b is detected and regardless of the presence or absence of an anisotropy of the surface 12b, the observation of the crystal growth process of a multilayer film can be made. Moreover, this observation is suitable for the spot observation of a heteroepitaxial growth.
