Title: Production of alloyed galvanized steel sheet
Inventor: MIZUYAMA YAICHIRO
IPC: C23C2/28
Filed: 1988-12-23
Abstract: PURPOSE:To form an alloy layer on the surface of the subject steel sheet with a delta1 phase simple substance and to improve its weldability and workability, at the time of heating a galvanized steel sheet and alloying it, by accelerating the heating speed under specific conditions. CONSTITUTION:At the time of heating a galvanized steel sheet, the heating speed from 420 deg.C in the process of the heating is regulated to >=10 deg.C/sec and the steel sheet is heated to the alloying temp. of >=530 deg.C. As the result, a delta1 phase is formed on the surface of the alloy layer. A surface film effective for spot welding is easy to form by forming the surface of the alloy layer with a delta1 phase simple substance and the frictional resistance on the surface is furthermore reduced to improve the workability by the formation of the film on the surface.

IPC: H03F3/45
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a circuit preventing the variance of the conductance due to the variance of the grounded emitter current amplification factor of a transistor. SOLUTION: A first constant current source 10 supplying constant current to a first differential circuit 12 and a second constant current source 11 supplying constant current to a second differential circuit 14 are defined as the grounded emitter circuit having an emitter resistance. The input of the first constant current source 10 is connected with the input of the second constant current source 11 in common via a fifth resistance R5 . As a result, the output of the first constant current source 10 is strongly affected by the grounded emitter current amplification factor of a transistor from the output of the second constant current source 11 and the influence of the grounded emitter current amplification factor on the conductance of the whole of the circuit can be almost canceled.

Inventor: TAKAHASHI KAZUHIRO
IPC: F25C5/18
Filed: 1990-11-26
Abstract: PURPOSE:To accurately control the operation of an ice-making apparatus by detecting the change of the capacitances when ice exists between an inner box for an ice-storing casing which acts as a first electrode, and a second electrode which is fixed to the lower end of signal cable, which is covered for insulation and hung at a place above the inner box, and when the second electrode is in contact with the inner box. CONSTITUTION:When a space exists between an inner box 1A as a first electrode and an ice-detecting member 13 as a second electrode, the capacitance C between them is small because of the air. When the amount of ice storage is increased and finally the inner box 1A and the ice-detecting member 13 are brought to the state in which they are bridged by ice 10 having the permittivity higher than that of the air, the capacitance C between them is increased. The change of this capacitance C is used as an input signal for a switching means 14, and the switching means 14 inputs this signal from the ice-detecting member 13 through a lead wire 15 and performs switching action. The change of the signal from this switching means 14 is transmitted to a control circuit through a signal cable 12 having a connector for a control circuit 20 in an ice-making apparatus, and the operation of the ice-making apparatus is stopped.

Abstract: PURPOSE: To make it possible to shift the frequency downward by shifting a chirp, which is applied by a laser amplifier and is nearly rectilinear in the central partial ranges of respective pulses, by as much as the effective part in the phase. CONSTITUTION: A modulated laser device 11 generates the output stream of the light pulses and supplies the stream to the satd. semiconductor laser amplifier 13 through a fiber segment 12. The laser amplifier 13 amplifies the light pulse stream and simultaneously chirps the stream and supplies the stream formed by the chirped light pulses to the optical fiber segment 14 in response with the stream from the fiber segment 12. The fiber segment 14, unlike the fiber segment 12, exhibits marked light dispersion and chirps the stream and, therefore, has a Fourier spectrum 17 which is asymmetrical and is centers at the frequency f01 lower than ordinary f0 . As a result, the remarkable phase modulation of the light beam and the modulation of its frequency are made possible.

Inventor: KENESU ROI BUTSUTSU
IPC: F16H59/26
Filed: 1988-12-22
Abstract: PURPOSE: To make a shift operation of good performance by stopping gradual decrease of an engaging oil pressure when slip in a high-speed side speed ratio mechanism exceeds a specified value at the time of power-on down shift, and disengaging and engaging when the low-speed side slip becomes below the specified value. CONSTITUTION: At a power-on 3-2 down shift, a control module 34 gradually decreases the torque of an off-going (third speed) clutch 90 and starts supplying the oil pressure to a hydraulic servo 120 of an on-coming clutch (second speed friction brake) 118. When slip of the friction clutch 90 exceeds the reference value, the gradual decrease of the torque is stopped temporarily. If meantime the input speed of the transmission 16 increases continuously and the slip speed of the second speed band brake 118 sinks below the reference value, the clutch 90 is disengaged and the band brake 118 is engaged at the same time, and the shift is completed. Thus a down shift can be made in good performance without generating a large shock.

Filed: 1989-12-15
Abstract: PURPOSE:To obtain a multilevel display without reducing display brightness and also without deteriorating the quality of the display even in the case that a display area for a half tone display is enlarged by using a system for thinning out frames and a system for modulating a pulse width jointly. CONSTITUTION:A data 15 for thinning out the frames is generated in accordance with a lower display data 14, and a control for modulating the pulse width is performed based on the thinning out data 15 and an upper display data 13. Then, the data of two bits which are transferred to a display with one dot is rearranged with reference to the dots in adjacent X directions and Y directions by a phase inversion circuit 9. By rearranging the data, the phase of an impressed pulse is inverted and also the noise caused by a rise and an fall counterbalances each other, the reduction of the display brightness caused by the enlargement of the half tone display area is eliminated. And also, the processing of thinning out the frames is performed by a frame thinning out circuit 4 in an oblique line dot pattern state. Thus, a counterbalancing effect by a phase inversion is effectively used.

Title: Device for detecting movement of anatomical sample receiving nmr analysis

IPC: G01R33/28
Filed: 1990-11-29
Abstract: PURPOSE: To provide a novel movement detector to be used in forming the NMR image of high resolving power by directing an optical sensor having the output corresponding to the intensity of the illumination to a selected part of an anatomical sample, monitoring the output of each optical sensor, and detecting the change in the output corresponding to the movement of the sample. CONSTITUTION: In order to facilitate detection of the movement by the change in the reflection amplitude characteristic, optical sensor 14-1 to 14-5 are provided around the sample part selected so as to reflect the incident light, and the visual field of each optical sensor is brought into correct contact with a pupil 10b of the sample eye. Each corner light sensor receives the reflected light from the iris 10a of the eye. Because the reflection rate of the iris is different form that of the pupil 10b, the eye is moved, and the output of the optical sensor is changed if a part of the pupil is moved in an arbitrary part of the visual field of the optical sensor which is formerly occupied by the iris of the eye.  Thus, the output of each corner light sensor when the eye is correctly placed in the center is stored as the reference level, and generation of any movement can be indicated by periodically comparing the present sensor output with the reference level.
