Title: Surface coil for mr imaging device
Inventor: SHIMIZU TAKAYUKI
IPC: A61B5/055
Filed: 1989-09-20
Abstract: PURPOSE:To select a desired photographing region by setting dimensional shape of a non-magnetic conductive material itself, in which a surface coil is formed, arbitrarily deformable to be matched with an interest region. CONSTITUTION:For instance, when a method of changing a photographing interest region of a surface coil in a longitudinal direction is shown, an alphabet A shows a condition that a flexible non-magnetic conductor 22 is extended. An alphabet B shows a condition that a flexible coil material is contracted with the photographing interest region decreased as compared with A, and irradiation efficiency or receiving sensitivity of this part is increased. An alphabet C shows a bending part of the coil material. A fold overlapping length of the flexible coil material can be arbitrarily changed to be matched with the photographing region. When shape of the coil material is thus changed, by changing its inductance, a resonance frequency is displaced. Accordingly, the compensation is performed by a synchronizing circuit 23.

Title: Control device for elevator
Inventor: KASAI SHOJI
IPC: B66B3/00
Filed: 1989-09-20
Abstract: PURPOSE:To prevent communication of erroneous data and to continue the normal operation of an elevator without stopping control of a microcomputer under normal operation by a method wherein when one computer has failed in operation, only the computer is prohibited to be written in a memory. CONSTITUTION:When failure in operation occurs on the one microcomputer side, for example, in the case of failure in operation on the microcomputer 1 side, the output of an AND gate 5 is prohibited by means of an output from a failure in operation detecting circuit 3. Further, by stopping a feed by a power source by means of a transistor 4, only a port on the L side of a duel port RAM 6 is brought into a state to be incapable of reading and writing. As noted above, by logically stopping a feed to the AND gate 5 through detection of failure in operation, the microcomputer 1 is prevented in a hard manner also from erroneous writing during runaway. Further, since a PB 5 employs a battery back up source, erroneous writing during shut off of a power source can be prevented from occurring.

Title: Pressure relieving device
Inventor: ISHIKAWA SHINICHIRO
IPC: B61D27/00
Filed: 1989-09-20
Abstract: PURPOSE:To suppress the deflection of a deflecting plate below a certain value and prolong the lifetime by furnishing an air supply device and a gas exhaust device with deflecting plate whose draft area varies according to the pressure difference between inside and outside of the car, and installing a buffer mechanism consisting of an elastic material at least on one side of the upstream and downstream of each deflecting plate. CONSTITUTION:In normal ventilating condition, wind is sent by a blower in the direction of arrow, and an upstream deflecting plate 20 is held in deflected condition and restrained by a stopper 21. When an abrupt pressure difference is generated between inside and outside the car while it is situated in a tunnel, etc., the pressure difference between in front of and behind each deflecting plate 20 should generate deflection, and the draft area will vary in compliance with the direction and size of the pressure variation applied. At this time, a buffer mechanism 22 having resilience will restrain the deflection to a certain degree. Accordingly the stress in the fixed part of the deflecting plate 20 does not increase after contacting this buffer mechanism 22, which suppresses self-exciting vibration generated over a certain limit of the deflection amount, and the pressure change in the car will be reduced and the lifetime of deflecting plate 20 prolonged.

Filed: 1994-09-09
Abstract: PURPOSE: To enable an operator to safely work on his operation by providing a means to move a base back and forth so as to pressurize a roll against the outer circumferential face of a coil. CONSTITUTION: A frame 2 is attached to a base 1 with a connecting means 10 so as to freely rotate around orthogonal three axis lines. A hydraulic cylinder 5 is connected to the base 1 so as to pressurize a roll 3 against the outer circumferential face of a coil. While the frame 2 is pressed against the base 1 with a spring 16, by means of the spherical recessed part 11 of the base pushed by the cylinder 5 and the spherical projecting part 13 of the frame, a motion similar to a universal joint is made possible with both spherical faces. The two pieces of roll 3 are attached parallelly to the frame 2; consequently, when the rolls are abutted on the coil, the frame 2 and the base 1 slide on the spherical face, and the axial lines of these rolls 3 become parallel with that of the coil. Thus, the axes of sunbber rolls can be always made parallel with each other.
