Title: Electromagnetic brake for elevator hoist
Inventor: SHIMADA MICHITOSHI
IPC: B66B11/08
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a stable braking force with a simple structure by dividing a brake body into a doughnut shape, and independently brake-operating the divided split brake bodies to eliminate the sharp angle part to the rotating direction of a rotator. SOLUTION: In braking, when the current carried to the coil 2 of a stator 1 is cut, a split armature 17 is pressed by a coil spring 21 since the electromagnetic force is eliminated. A split armature 18 is pressed by a coil spring 22. A rotor 15 is nipped between a slide member 16 adhered to a fixed plate 3 and a slide member 19 adhered to the split armature 17, and also nipped between the slide member 16 adhered to the fixed plate 3 and a slide member 20 adhered to the split armature 18 to generate a braking force. In braking, the braking force is generated by two systems of the split armature 17 and the split armature 18.

Title: Color picture tube
Inventor: KIDA KINJI
IPC: H01J29/07
Filed: 1987-01-27
Abstract: PURPOSE:To improve color purity deterioration such as color convergence error and color phase irregularity by making conductivity in the central part and in the peripheral part of the mainface effective part of a shadow mask in an electron absorption layer. CONSTITUTION:An electron absorption layer is formed on the side of an electron gun 6 of the main face effective part of a shadow mask 7 and this electron absorption part is so made that conductivity is different in the central part and the peripheral part of the main face effective part. Conductivity of the electron absorption layer can be made lower in the central part than in the peripheral part of the main face effective part of the shadow mask 7 being gradually lowered in proportion to proceeding to the central part from the peripheral part of the main face effective part of the shadow mask 7. Since the electron absorption layer such as to make a deceleration electric field, which stronger deflects in the direction going away from a tube axis even when the shadow mask generates a doming phenomenon, is formed on the shadow mask, a mislanded electron beam is deflected to return to the original position. Thereby, possibility to generate color convergence error is further reduced.

Title: Seal inserting method
Inventor: HIRAMATSU MOTOI
IPC: B23P19/02
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To set a seal in a specified position in a normal state by returning a lip to its original state even if the lip is torn off during seal inserting. SOLUTION: For inserting a seal 10 having a lip 10A into a shaft body 14B, a circumferential groove 14C is formed beforehand in the outer peripheral surface of the shaft body 14B. When the seal 10 is inserted from one end of the shaft body 14B, the tip of the lip 10A is positioned in the circumferential groove 14C, and then the seal 10 is moved in a direction opposite the inserting direction. Thus, even if tearing-off occurs in the lip 10A, the lip 10A is hooked on the edge part 14E of the circumferentical groove 14C and the tearing-off is easily corrected.

Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To make no hindrance is caused in terms of design. SOLUTION: A connecting mechanism B has curved surface members 10a, 10c and 12a which exist around the connecting section A of a bottom end front edge 6a of a display device 6 housed in a recessed part 9 and an upper end edge 9a of a recessed part 9 continuous with this bottom end front edge 6a as the central axis and are respectively vary in the distances from this central axis.

Inventor: KONO TSUKASA
IPC: H01B13/00
Filed: 1988-01-27
Abstract: PURPOSE:To obtain an oxide superconductive wire which is high in critical current density and high in mechanical strength, by applying forging process to an intermediate sintered body at a consolidation degree less than the specified ratio of logical density prior to sintering, and shortening heat treatment time at a low heat treatment temperature so as to form the final sintered body at the desired consolidation degree. CONSTITUTION:An intermediate sintered body 1 at the consolidation degree less than 75% of logical density is inserted into a tube body 2 made of metal and cold processing is applied so as to obtain a complex 3 at a consolidation degree of 75-80% of the logical density. Next, an outside metal sheath is removed from a consolidated substance and the exposed complex 3 is applied with diameter decrease processing by a rotary swaging device A. In this diameter reduction processing, since the complex is decreased for diameter while being forged by plural dies 6 which reciprocate while operating the device A, the diameter can be decreased at a large processing rate. And when the diameter decrease of the complex 13 does not reach the desired value, it is processed with a device A equipped with dies with smaller formation space, and when it reaches the desired line diameter, a sheath material is removed and the complex is applied with heat treatment so as to obtain a final sintered body at a consolidation degree more than 92% of the logical density.

Title: Analog/digital conversion controller
Inventor: OOIWA GIHEI
IPC: G05B1/01
Filed: 1983-02-02
Abstract: PURPOSE:To apply an A/D conversion with high accuracy to the voltage higher than the reference voltage of an A/D converting part by applying an A/D conversion to the difference voltage between the output voltage of a detector and that of a reference voltage generating part. CONSTITUTION:The output voltage EO of a detector 1 and the output voltage EA of a reference voltage generating part 4 are supplied to a differential amplifying part 7 through an impedance converting circuit 8 to deliver the difference voltage Ei=EA-EO. In this case, the part 4 is switched and controlled so that the voltage Ei is less than the reference voltage Er of an A/D converting part. As a result, an upper digit part is obtained from the part 4 although the voltage EO is higher than the voltage Er. Thus it is just needed to convert only the voltage Ei corresponding to a lower digit part through the A/D converting part. Therefore an A/D conversion is ensured with high accuracy even with the voltage higher than the voltage Er.

Inventor: SHIMADA KEIJI
IPC: B62B3/06
Filed: 1990-01-26
Abstract: PURPOSE:To facilitate loading/unloading by positioning the height of a load always constant independently of the total load by regulating the transfer range of a transfer member according to the turning range of a turning member and selectively operating a plurality of elastic members which support the loading board. CONSTITUTION:When a load is applied on a vertically movable loading board which is installed on a transport vehicle which is not shown on the figure, a loading board suspending wire 8 arranged on the undersurface of the bottom plate of the transport vehicle pulls a hook 12, and the second elastic member 11 is extended. At the same time, the second wire 20 and a shifting means 23 are pulled. However, when a turning member 18 is operated in the direction crossing at right angle with the pulling direction by an operating member 4, the loading board is moved vertically only by the elsticity of the second elastic member 11. As the turning member 18 is turned and set close to the pulling direction, the distance in which a transfer member 23 transfers becomes long. Accordingly, the loading board is moved vertically by the elasticity of both the first and second elastic members 19 and 11.

Title: Variable valve timing mechanism
Inventor: YORITA HIROSHI
IPC: F01L1/344
Filed: 1995-02-03
Abstract: PURPOSE: To suppress backrush noise by charging oil in a circular space formed by a seal ring and a seal ring groove, and forming a narrow part for partially throttling flow of oil in the space. CONSTITUTION: In a fine circular space 13b between an outer ring 17a and an inner ring 17b, a center of an inner circle of the outer ring 17a is dislocated from a center of an outer circle of the inner ring 17b. The joining form of is thus going to change abruptly with relative rotation of the rings 17a, 17b. Oil is charged in the fine circular space 13b for starting a variable valve timing mechanism, and abrupt deformation is prevented due to viscous resistance. When rotation of a timing pulley 3 is transmitted to a cam shaft 2, oscillation of a piston 12 is suppressed in a rotational direction in a gap backrush between a helical spline 4b of a housing 4 and a helical spline 12b of the piston 12. Backrush noise is thus suppressed.
