Title: Mash seam welding machine
Inventor: OKABE YOSHIO
IPC: B23K37/04
Filed: 1994-09-08
Abstract: PURPOSE: To secure a small lap margin by clamping the uniform lap margin formed over the whole length of a weld joint part until the welding is completed, rapidly cooling the weld with the cooling medium immediately after the welding to give the inwardly bending force to the non-welded part. CONSTITUTION: When end parts of two metallic sheets are held by clamping devices 10, 11, a moving frame 1 is moved and a shear 7 cuts the end parts of the metallic sheets. After the cutting is completed, the metallic sheets are tilted from the clamping device 11, and the clamping device 10 is advanced in the condition where the end parts of the metallic sheets are lifted, and the cut parts of the metallic sheets are slightly lapped over the whole length in the width direction. The moving frame 1 is advanced, and the lapped joint parts are welded by rotary electrodes 4, 5, and then, the cooling medium is ejected from a cooling nozzle 12 provided on the outlet side of the electrode to rapidly cool the welded part.  The bending moment is generated toward the inner side of the rapidly cooled welded part and the non-welded metallic sheets, and the lap margin is kept constant to enable the continuous welding of the joint with less lap margin.

Title: Stent
Inventor: VON OEPEN RANDOLF
IPC: A61M29/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the danger of restenosis of a vessel in a stent implanted region. SOLUTION: A stent 1 comprises a stent body 2 with at least two different wall thickness (WH, WE1, WE2). The longitudinal flexible characteristic of the stent can be different by differentiating wall thickness. The occurrence of a vessel stimulating state in a stent implanted region can therefore be prevented to considerably reduce the danger of restenosis in the region.

Title: Inspection plate and manufacture thereof
Inventor: SUZUKI TATSUO
IPC: G01N33/48
Filed: 1985-10-28
Abstract: PURPOSE:To enable a material being inspected to be held in a space wherein no adhesive layer is present in the gap between a cover plate and a base plate by fixing the cover plate and the base plate together with double-coated adhesive tape. CONSTITUTION:An inspection plate 1 is constituted of a cover plate 2, a base plate 3 and double-coated adhesive tape 4. The cover plate 2 and the base plate 3 are made from about 170mum thick and about 500mum thick acrylic resin sheets by a blanking. The tape 4, coated with an about 30mum thick rubber elastomer on both surfaces of an about 40mum thick polyester film as a substrate, is about 100mum thick and made to a configuration A by a blanking. The tape 4 is overlaid upon the upper surface of the base plate 3, then the cover plate 2 is overlaid upon the upper surface of the tape 4 and those are pressed to be adhered. Thus, the inspection plate 1 can hold independent spaces 5 in the gap between the cover plate 2 and the base plate 3.

Title: Drive circuit for mosfet
Inventor: OTSU SATOSHI
IPC: H03K17/04
Filed: 1991-09-20
Abstract: PURPOSE:To attain high speed switching even when an input capacitance is large by selecting a different voltage fed between a gate and a source from an initial period when a MOSFET transits to the ON state from other period. CONSTITUTION:When a voltage of a drive signal source 3 reaches a high level, since the gate-source voltage of a driven MOSFET 1 is lower than the reference value of a reference voltage source 9, a comparator 10 controls a switch 8 and a drive circuit 2 outputs the voltage of a 2nd drive circuit power supply 7. Thus, the gate-source voltage is increased and when the voltage reaches the threshold voltage of a FET 1 or over, the FET 1 is turned on. When the voltage reaches the reference voltage or over, the comparator 10 controls the switch 8 to supply power to the circuit 2 from the 1st drive circuit power supply 4 and to charge up a capacitor 5. When a signal source 3 reaches a low level, an inverter 12 closes a 2nd switch 11 to short-circuit a capacitor 5 thereby decreasing the gate-source voltage and when the voltage reaches a threshold voltage or below, the FET 1 is turned off. Thus, the switching time is reduced.

Title: Speed controller for motor
Inventor: KUBO KENJI
IPC: H02P29/00
Filed: 1994-10-05
Abstract: PURPOSE: To control a motor and a mechanical load without vibration and with a high response by arithmetically calculating the acceleration at the load side from a torque current and speed, by calculating the acceleration at the motor side and by compensating a torque current command value by respective calculated values of acceleration. CONSTITUTION: In a load acceleration computing element 10, an axial torque acting to a motor shaft is calculated from a torque current I1 of a motor and a motor speed ωm . This axial torque corresponds to a torque acting to a motor shaft as a reaction from a mechanical load during deceleration of the mechanical load. Therefore, by this axial torque, the acceleration α1 at the mechanical load side can be calculated. On the other hand, in a motor acceleration computing element 11, the motor acceleration αm is calculated by differentiating a detected value ωm of a motor speed with time.  By doing the above, not only the vibration restriction at the mechanical load side but also the vibration restriction at the motor side can be achieved at the same time, so that axial vibration restriction with good responses can be performed without making the motor control system unstable.

Title: Method of starting ultra-low frequency amplifier circuit
Inventor: MURAO EIJI
IPC: H03F1/00
Filed: 1985-10-28
Abstract: PURPOSE:To decrease extremely the start time by providing a start circuit comprising a switch circuit driven by a timer and using a start circuit at starting so as to charge a time constant circuit. CONSTITUTION:The start circuit A has time constant comprising a resistor R1 and a capacitor C1. Since a timer is connected to an inverting circuit 2 outputting an L level for a prescribed time after a power supply VCC is applied via a resistor R2, the inverting circuit 2 outputs an 'H' level during the period of the timer output L. The output of the inverting circuit 2 is given to a switch circuit 3 to short-circuit a resistor R3 of the time constant circuit connected to an input terminal of an ultra-low frequency amplifier circuit. The capacitor C2 of the time constant circuit is charged rapidly by the short-circuit of the resistor 3 so as to operate the ultra-low frequency amplifier circuit.

Title: Grounding circuit of electric rolling stock
Inventor: KOYAMA SHIGERU
IPC: B60L3/00
Filed: 1985-10-30
Abstract: PURPOSE:To prevent a noise current from flowing to rails by mounting an earth brush for a feedback circuit and an earth brush for grounding a body and a containing box on a common axle. CONSTITUTION:An earth brush 3 for a feedback circuit and an earth brush 3a for grounding a body 1 and a containing box 6 are both mounted on the same axle 2, and wired to the axle. A high-frequency noise current iN1 flows from the box 6 through a floating capacitance 12 to the body 1 and through the brushes 3a, 3 and the axle to the earth side terminal of a filter capacitor 8. A noise current iN2 flows from mounted wirings through floating capacitances 13a, 13b to a body 11 and through the same route to a filter capacitor 13. Since the noise currents do not flow to rails, the influence to devices on the ground side can be minimized.
