Title: Method and device for identifying unknown system by adaptive filter
Inventor: SUGIYAMA AKIHIKO
IPC: H04B3/23
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To reduce an error by updating coefficients in a state from the start of adaptive operation till a prescribed valid tap number of times of updating is conducted and in a succeeding states through the use of a specific step size respectively so as to execute tap position control accurately for nonstationary input signal. SOLUTION: When the total sum of power of input signals from a path switch 7 obtained by an input evaluation circuit 72 is smaller than a prescribed number, a switch 75 is used to select zero to omit update of a coefficient from a coefficient generating circuit 30. When the sum is larger than the prescribed number, a step size μ1 or μ2 through a switch 78 is selected and fed to the coefficient generating circuit 30, by which the coefficient is updated depending on the step size μ1 or μ2 . Then a ratio of the total sum of the power of the input signals from the input evaluation circuit 72 to the signal power fed to the coefficient generating circuit 30 is obtained. When it is higher than a prescribed value, counting of a counter 86 is stopped to delay a generating timing of a control signal.  On the other hand, when a minimum coefficient detection circuit 83 detects a minimum value, the switch 75 selects zero and the update of coefficient by the coefficient generating circuit 30 is not conducted.

Title: Prevention of base metal deposition of molten metal flowing port
Inventor: HAMAI KAZUO
IPC: B22D41/18
Filed: 1987-12-24
Abstract: PURPOSE:To ensure the opening operation of a nozzle by forming the tip part of a stopper and the nozzle forming a flowing port with a conductive refractory and feeding the current for heating with electrification between the both. CONSTITUTION:The nozzle stopper 5 and upper nozzle 6 of a tundish 1 is composed of the refractory of an alumina - carbon material having electric conductivity and electrodes 12, 13 are respectively fitted thereto. The current for heating with electrification is fed between the stopper 5 and upper nozzle 6 via the electrodes 12, 13 from an electrode 14. In this case, a bit heating action is received because the stopper 5 and upper nozzle 6 themselves respectively heat and the contact part of the both has a big contact resistance. The solidified deposition of the base metal is thus prevented due to the contact part of the stopper 5 and upper nozzle 6 being maintained at high temp. Consequently the opening operation of the nozzle 6 is ensured.

Title: Method for treating positive resist
Inventor: ENOMOTO JUN
IPC: H01L21/027
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To suppress foaming of N2 in a resist so as to prevent resist pattern defects resulting from foaming, by suppressing the exposing energy at a time when exposing edges of a substrate by dividing the exposure into several times. SOLUTION: An edge exposure of a substrate 1 is divided into several times so as to suppress the exposing energy at a time. Since intensity of exposed light on the edge is suppressed to a low value in the above-mentioned way, foaming of N2 4 from the inside of a resist 2 caused by a photochemical reaction which occurs when exposing can be minimized. Therefore, occurrence of short circuits or pinholes in a resist pattern caused by the foaming of the N2 4 can be prevented. In addition, since the edge exposure is performed in several times with a low intensity of light, the removal of the resist on the edge section of a wafer which is the primary purpose of the edge exposure can also be carried out.

Title: Driving method of thyristor
Inventor: NAKAGAWA AKIO
IPC: H03K17/732
Filed: 1987-12-28
Abstract: PURPOSE:To make it possible to turn off a large current, by imparting a reverse bias between a second emitter layer and a second base layer under the state a MOS transistor is kept on with a first gate electrode when a MOS-GTO is turned off, and turning off the MOS transistor. CONSTITUTION:Under the state an on voltage is slightly increased, a voltage, which is applied to a first gate electrode 6, is made to be zero or less and a channel is quenched. Then, electron injection into a first base layer 2 from a second emitter layer 4 is completely stopped. Thus an element is turned off. When the element is turned off, a part between a second emitter layer 4 and a second base layer 3 is reversebiased with a second electrode 8. Even if a thyristor operation is finished, a uniform current flows through the entire element with a MOS transistor. Thereafter, the MOS transistor is turned off, and the concentration of the current at the time of turn-off is prevented. Thus the entire element can be turned off uniformly. Therefore a large current can be turned off.

Abstract: PURPOSE:To display surely a vibration-restraint function even if vibration force is small. CONSTITUTION:A weight 11 is provided at a mass body 6 so as to be able to be moved horizontally, and at the same time a ball screw mechanism 12 to move the weight 11 advancingly and retreatingly is provided at the mass body 6. When a structure 1 vibrates along the movement direction of the mass body 6, the ball screw mechanism 1.2 moves the weight 11 in the vibration direction of the structure 1. The mass body 6, clue to its reaction, is pushed in the opposite direction to the vibration direction of the structure 1, that is, in a direction restraining vibration, and is easily moved. Even in a case in which force added to the structure 1 is small due to a small-scale earthquake or a wind or the like, vibration-restraint operation is to be displayed surely. As the mass body 6 can be easily moved even against small vibration force, vibration can be restrained that much over a wide range.
