Title: Superconductive magnetic resistance element
Inventor: TOYAMA MANABU
IPC: H01L39/16
Filed: 1990-10-31
Abstract: PURPOSE:To achieve a superconductive magnetic resistance element with a proper resistance change rate for a magnetic field with a wide range of values by changing a shape or a sectional area of a section which crosses a current flow path of a superconductor along the current flow path. CONSTITUTION:When a magnetic field is applied to a superconductor 1 which constitutes a magnet-sensing part and a constant current is conducted between electrodes while maintaining temperature below crystal value, the value of a part where the value of magnetic field for transition to resistance state is the greatest and the value of a part where the value of the transition magnetic field is the smallest can be changed freely by changing a shape or a sectional area of a section of the superconductor 1. In this manner, by changing the shape or the sectional area of the section of the superconductor 1 along the current flow path and by selecting the way of this change properly, dependence of resistance value of a magnetic resistance element on magnetic field can be optimized and a superconductive magnetic resistance element with a proper resistance change rate for a magnetic field with a wide range of values can be realized.

Title: Optical disk inspection device
Inventor: SATO YASUSHI
IPC: G11B7/08
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To easily execute the inspection having abundant contents in a short time by performing adjustments and controls so that plural optical detection parts whose characteristics are different from each other, detect signals of tracks on a rotating optical disk to be inspected while successively tracing tracks. SOLUTION: Optical detection parts 14A, 14B being at positions almost symmetric with respect to the center of a rotating optical disk 10 to be inspected detect information of tracks while their positions and focuses are controlled by servo circuits 16A, B. A control circuit 18 controls the circuits 16A, B and properly selects objective lenses of the detection parts 14A, B according to the pitch and the width of the track of the disk by receiving both information. When outputs of both optical detection parts having relatively large and small spot widths by this result constantly coincide with each other, the disk is judged to be a nondefective disk in which a faulty trace and a faulty information detection are not present. Thus, since plural kinds of inspection results are obtained by a single inspecting process, the inspection having abundant contents is executed in a short time.

Abstract: PURPOSE:To reduce the wt. of a head and to increase a recording speed, by constituting at least a part of the constitutional member of a magnetic circuit for driving a wire by magnetic force of a composite member formed by mixing a magnetic powder and a resin. CONSTITUTION:In a head, a magnetic circuit for driving a wire 2 is constituted as a closed magnetic path consisting of a coil core 6a, a yoke 6, a spacer 12, an auxiliary yoke 13, and armature lever 15 and a movable core 16. The movable core 16 is formed from a composite material formed by mixing a magnetic powder and a resin. As the magnetic material of the magnetic powder, one having saturated magnetic flux density higher than that of pure ion is used and, when the mixing ratio of the magnetic powder and the resin is properly set, the quantity of the magnetic flux PHI flowing to the movable core 16 can be kept equal and, by lowering the specific gravity of the composite material through the resin which is low in specific gravity, the equivalent mass of the movable core 16 can be reduced. Therefore, the operational speed of the movable core 16 is increased to make it possible to increase that of the wire 2 operating in conjunction therewith and a recording speed is increased.

Title: Electric railcar main circuit system
Inventor: WATANABE ASAKI
IPC: H02P5/50
Filed: 1994-11-28
Abstract: PURPOSE: To reduce the generated torque to smaller value in the same slip frequency and to eliminate the slip or glide of an axle by increasing the rotor resistance of one of a plurality of induction main motors which are energized from the same PWM-controlled inverter from that of the other motor. CONSTITUTION: An electric railcar main circuit system fetches power from an electric overhead line, converts it to AC power by a PWM-controlled inverter 4, and supplies it to a plurality of induction main motors 5a to 5c, 5d'. The secondary resistor R'2 of at least one of the energized motors 5a to 5c, 5d' such as, for example, 5d' is increased larger than that R2 of the other motors 5a to 5c. Thus, since the motor 5d' can decrease the torque in the same slip as those of the other motors 5a to 5c, large slip or glide is suppressed without adding any other unit, thereby improving the acceleration or deceleration of the railcar.

Title: Embedding work method for non-cut and cover pipe
Inventor: KORIYAMA MASAOMI
IPC: E21D9/08
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide an embedding method for a non-cut and cover pipe capable of reducing the frictional resistance between a pipe material and ground and smoothly inserting the pipe into the ground and obtaining a sufficiently long embedding length and improving the efficiency of the whole embedding work. SOLUTION: As a vibrating means is integrally arranged in a connection means 14 to vibrate a pipe material in the ground when diametrically broadening the ground by a reamer 13 and drawing in the pipe material 20, it prevents the ground 30 at the periphery of the pipe material 20 from closely sticking to the ground 30, and it accelerates intrusion of fluid for excavation in between the pipe material 20 and the ground 30 to reduce the frictional resistance therebetween. Hence, a limit in which the pipe material can be drawn in without breakage on the way can be widened and the embedding distance brought by one time of drawing pipe can be set longer and the number of a series of works of drilling and drawing in of pipes can be reduced to enable remarkable reduction of the construction period and cost.
