Title: Method and apparatus for collecting projection data in nmr-ct device
Inventor: SUZUKI HIROKAZU
IPC: G01R33/54
Filed: 1982-06-21
Abstract: PURPOSE:To obtain a definite selecting surface simply and readily, by measuring the resonant signal of a specified atomic nucleus, under the state magnetization of the entire part other than the part, which corresponds to the specified cross sectional area of the region where an image can be picked up, is selectively saturated. CONSTITUTION:A current is flowed through coils 3-1, 3-2, and 5 so that magnetic fields are superimposed on a constant static magnetiv field caused by a coil 1 and a power source 2. Then, a slant linear magnetic field is formed in a region to be measured. A resonant frequency is made to be dispersed in the slant direction. Then the frequency of the radio wave generated by an oscillator 7 is swept within a frequency range corresponding to a part which is not selected. The signal is applied to a body to be checked through a probe head 15, the magnetization only at the nonselected part is saturated. Then the current which is flowed to the coils 3-1, 3-2, and 5 is adjusted. Thereafter 90 deg. pulses, which are obtained by modulating the radio wave with an intended resonant frequency from an oscillator 10, are applied to the body to be checked. The resonant frequency is inputted to a digital computer 19 through a receiver 17 and an AD converter 18. Then the image of the density distribution of the reorganized specified atomic nucleuses is dislayed on a display device 20.

IPC: H01H33/64
Filed: 1994-05-20
Abstract: PURPOSE:To obtain a disconnecting switch with resistances without any lowering of dielectric strength by locally lessening the diameter of an insulating support rod for fixing an intermediate shield to a fixed-side electrode via a presser board, a spring, etc., according to the positions of shields and the presser board arranged among the plural resistances. CONSTITUTION:An intermediate shield 9 is fixed to a fixed-side electrode 7 by an insulating support rod 180 passing through shields 82 among the plural resistances 81 via a presser board 83 supported onto the electrode 7 by means a spring 84. The rod 180 has its diameter locally lessened according to shift distances, in a direction orthogonal to the axis of the rod 180 due to the dimensional tolerances and arrangements of the resistances 81, the shields 82 and the presser board respectively so as to form a large-diameter part 180a, a medium-diameter part 180b and a small-diameter part 180c. Thus a disconnecting switch with the resistances 81 can be assembled without the insulating rod 180 brought in contact with the resistances 81 while causing neither concentration of electric fields nor lowering dielectric strength even if the rod 180 is put in such a condition that its axial line is deviated at the time of assembling the switch.

Title: Collision preventing device of unattended inductive car
Inventor: KANAZAWA JIYUNPEI
IPC: B61L23/14
Filed: 1980-08-04
Abstract: PURPOSE:To install a ground equipment easily and also at a low cost, by placing a receiving antenna and a transmission antenna as a ground equipment in each block section, and also providing a transmitter and a receiver on an unattended inductive car. CONSTITUTION:When an unattened inductive car enters a block section 2b, a blocking signal generated by a transmitter is supplied to a receiving antenna 13b. The antenna 13b receives this blocking signal and supplies it to a transmission antenna 16a through a transmission line 15a. As a result, the blocking signal is outputted from the antenna 16a and blocks the section 2b. During this period, if an unattended inductive car behind runs into a block section 2a, the blocking signal which is outputted by the antenna 16a is supplied to a receiver of the following car. The receiver detects this blocking signal, detects that the section 2b is blocked, and stops running of the following car. Thereafter, when the unattended inductive car which has existed in the section 2b goes out of the section 2b, the blocking signal comes not to be received by the antenna 13b, the blocking signal outputted from the antenna 16a becomes off, and the unattended inductive car behind starts to advance.

Filed: 1990-04-23
Abstract: PURPOSE:To nondestructively measure film thicknesses by providing 2nd pattern forming parts without having phase shift films further to the phase shift mask having 1st pattern forming parts and determining and comparing the best focus positions of both. CONSTITUTION:Light transparent parts 12 which allow the transmission of exposing light without phase shifting are provided in correspondence to the patterns to be formed and the phase shift parts 11, 11a to shift the phase of the exposing light are formed in proximity to the transparent parts 12. The focus is changed by using this mask and the resist on the substrate to be exposed is thereby exposed, by which the patterns are transferred to the resist. The best focus position of both patterns of the case of the presence of the phase shift films and the case of the absence thereof and the difference between both are determined by measuring the transferred patterns. The deviation quantity of the focuses can be theoretically determined by simulation from the shapes, materials, etc., of the patterns and the phase shift films and, therefore, the film thicknesses are determined from the actually measured deviation quantity.

Title: Rubber crawler improved in performance against dislocation from wheel and its core metal
Inventor: UCHIDA SHINJI
IPC: B62D55/253
Filed: 1995-04-07
Abstract: PURPOSE: To restrain relative movement in the lateral direction with respect to an outer rolling wheel, and thereby prevent the occurrence of dislocation from the wheel by providing each projecting section at the center area section of each auxiliary angular section with respect to main angular sections. CONSTITUTION: In the core metal 1, each auxiliary angular section 5 is formed at wing sections 2 with respect to main angular sections 4, and the formation of each auxiliary angular section 5 makes each center area faced to the main angular sections 4 an inclined surface slack in inclination, and also makes each space interspaced from the main angular sections 4 narrow. When the core metal 1 thus formed, is incorporated into a rubber elastic body 10, and when relative movement in the lateral direction is made between an outer rolling wheel 30 and the core metal 1, the outer wheel 31 of the outer rolling wheel 30 is brought into contact with the inclined surface 6 of each auxiliary angular section 5, and the effect of taking the outer wheel 31 back to the main angular sections 4, is thereby exhibited.  Therefore, even if the quantity of looseness of the rubber crawler is large, the occurrence of dislocation from the wheel can thereby be reduced.
