Title: Thin film soi-mosfet and manufacture thereof
Inventor: MATSUMOTO HIROSHI
IPC: H01L21/336
Filed: 1990-11-05
Abstract: PURPOSE:To reduce a hole density and thereby to prevent a rise in potential due to accumulation of holes by a method wherein a recombination region facilitating annihilation of electrons and the holes is disposed near a back gate. CONSTITUTION:A region 2 containing many recombination centers facilitating annihilation of electrons and holes is disposed in a part near a back gate in the end of a source region wherein a hole density is the highest. The holes generated by impact ionization in the end of a drain region 4 flow into an Si substrate 5 and reach the recombination region 2. They are recombined therein with the electrons from the end of the source region 9 at a certain rate and the potential of the substrate 5 rises in a sufficiently low value and stops. In this way, the hole density is reduced by the annihilation of the electrons. According to this constitution, the rise in potential due to storage of the holes is prevented and thereby the lowering of a breakdown voltage can be held back.

Inventor: DEO TAKURO
IPC: H01J37/22
Filed: 1989-11-18
Abstract: PURPOSE:To expose a pattern at a proper position on a wafer with an electron beam without using a positioning mark by detecting the positions of pattern edge lines on samples in an auxiliary chamber and an exposure chamber, then determining the exposure point on the sample in the exposure chamber from the exposure point on the sample in the auxiliary chamber by calculation.

Title: Peak hold circuit
Inventor: KUROSHIMA HIROMOTO
IPC: G01R19/04
Filed: 1988-11-28
Abstract: PURPOSE:To make it possible to hold the peak of an input signal with fidelity substantially by a method wherein an output signal being reverse in polarity to a peak value held by a peak hold element is passed between the output node of an arithmetic circuit and the input node thereof. CONSTITUTION:In a peak hold circuit provided with an arithmetic circuit 5, a peak hold element connected to the output node of he circuit 5 and holding a peak value of an output signal appearing in the output node and a period channel connecting the peak hold element with the period input node of the circuit 5, a diode 8 and a resistor 14 are added thereto. The diode 8 is so connected as to be continuous for a signal being reverse in polarity to a peak-held signal. When an output of the signal being reverse in polarity appears in the output 16 behind the circuit 5, accordingly, the diode 8 operates to connect the output 16 onto the period input side behind the circuit 5 with a period resistance being zero nearly at all, and therefore the circuit 5 does not have an amplifying function almost at all for the reverse signal. Besides, the resistor 14 is a current-limiting resistor and a very small value thereof does not contribute to the amplifying function. Thus, an input signal can be peak-held with fidelity substantially.

Title: Opening and closing control device for elevator door
Inventor: KODERA TOSHIYUKI
IPC: B66B13/14
Filed: 1993-11-30
Abstract: PURPOSE:To improve safety of a utilizer and to prevent lowering of operation efficiency by limiting a speed during reverse operation when pull-in occurs. CONSTITUTION:A door position is calculated from the counting value of a pulse count unit and a motor speed is calculated from a change amount per an hour of a door position at S41a-S41c. When door closing operation by a reverse demand is not effected, a normal speed command value is read from an ROM. A torque command value Q responding to a difference from a motor speed is determined and a torque limit value Q0 responding to the position of a door is read at S41d-S41h. When the torque command value Q is lower than the torque limit value Q0, door opening operation is carried out based on the torque command value Q at S41i and S41j. Since, when pull-in occurs, the torque value Q exceeds the torque limit valve Q0, a reversion demand signal is outputted to an elevator control panel to stop door opening operation, and transfer to door closing operation is performed. In this case, a speed command value lower than a ordinary value is read from an ROM at S41l.

Title: Composite roll and its manufacture
Inventor: KODAMA HITOSHI
IPC: B21B39/00
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent cracking, etc., on a part of a carbon fiber reinforcing material even at the time of using under a high temperature condition by making an orientation ratio in a rolling circumferential direction of carbon fiber in a carbon fiber reinforcing carbon material layer less than 10%. SOLUTION: Carbon fiber in a sleeve 3 is orientated in two directions of an axial direction of the sleeve 3 and a circumferential direction on a circular cross section orthogonal with it. As metal constituting a rotation axis material 2 and a C/C composite constituting the sleeve 3 are different from each other in a coefficient of linear expansion, there is possibility of cracking on the sleeve 3 as thermal stress works between a roll main body 2 and the sleeve 3 in the case of using it under a condition where a temperature change is large,  but it becomes possible to make an expansion rate in the diametrical direction of the rotation axis member 2 and an expansion rate to the diametrical direction of the sleeve 3 roughly the same by restraining the number of carbon fibers orientated in the circumferential direction of the sleeve 3 down to less than 10% of the whole and to prevent cracking of the sleeve by thermal stress.
