Patent JP-H11195784-A (JP)
Title: Insulated-gate semiconductor element
Inventor: MURATA TOSHIO
IPC: H01L29/78
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To increase latch-up resistance of a semiconductor element, and at the same time, to lower the on-state voltage of the element. SOLUTION: Gate electrodes 13a and 13b associated with insulating films 14a and 14b are arranged in a base region 12 where carriers are diffused so as to narrow a carrier diffusing flow passage. In addition, emitter regions 15a and 15b are provided at the upper end sections of the insulating films 14a and 14b, in such shapes and arrangements that holes which passed through the carrier diffusing flow passage are apt to collect on an emitter electrode 18 nor on the emitter regions 15a and 15b of a parasitic transistor, and the resistance of a base region 16 becomes smaller. When an insulated-gate semiconductor element is constructed in such a structure, the hole concentration near the narrowed flow passage is increased and the on-state voltage of the element can be reduced by a conductivity modulating effect.  In addition, the parasitic transistor does not operate and an increase in latch-up resistance and a decrease in on-state voltage can be realized at the same time.

Filed: 1990-12-20
Abstract: PURPOSE: To rapidly detect a shift to a dynamic operation by transferring a measured value when the actually measured value at present time upon dynamic operation of an internal combustion engine is different from a preceding measured value or a counting process reaches its maximum value. CONSTITUTION: When, for instance, the value of the pressure of an intake pipe required for a control or an adjustment is determined, the content of a counter is first increased by one 10, every time a measurement is carried out. After that, it is examined 11 whether or not the counted value of the counter reaches the number of cylinders of an internal combustion engine. When a reply is YES, the counter is reset to zero. Then, the value PL of a load at the present time, that is, the instantaneous value of the pressure of the intake pipe is read to compare it with the preceding value PL-1 of the load. If PL<=PL-1 , the value PL-1 is used for a control or an adjustment. On the contrary, if PL>PL-1 , the value PL is used for a control or an adjustment. At this time, the counters are simultaneously reset to zero 17. Then, a new program process is started.

IPC: H01Q5/10
Filed: 1990-12-28
Abstract: PURPOSE:To miniaturize the antenna itself and to reduce its cost by providing plural antenna elements, using plural antenna elements at the time when a frequency is low, and using one antenna element at the time when the frequency is high. CONSTITUTION:One frequency of a two frequency antenna and the other frequency are denoted as f1 and f2, respectively. An antenna element 1 has dimensions for resonating to f1 and with respect to f1, the impedance Z becomes the impedance which becomes large enough. Accordingly, in them case of f1, the device is not influenced by an antenna element 2 and in the case of f1, it executes the same operation as only the antenna element 1 is installed. Also, in the case of f2, when the impedance Z is set so as to become a sufficient low value, the device operates as the antenna element being in a state that the elements 1, 2 in f2 are added. That is, the impedance Z is set so that the elements 1, 2 are operated simultaneously by a lower frequency in two frequencies, and only the element 1 is operated by a higher frequency. In such a way, a multi-frequency can be obtained.
