IPC: H01P1/205
Filed: 1993-05-19
Abstract: PURPOSE:To improve the symmetry of a straight capacitor by arranging an electrode conductor layer opposite to each of divided mutual coupling capacitors with point symmetry on a same lane in a multi-layer base so as to suppress a capacitance change due to a position deviation. CONSTITUTION:First and second electrode conductor layers 43a, 43b have a point symmetry pattern by using a cross point between a center line in the vertical direction and a center line in the horizontal direction of the surface of a 3rd dielectric layer 20 as a reference point and 3rd and 4th electrode conductor layers 47a, 47b have a point symmetry pattern by using a cross point between a center line in the vertical direction and a center line in the horizontal direction of the surface of a 4th dielectric layer 20 as a reference point. The conductor layers 43a, 43b, and 47a, 47b are extended respectively in the horizontal direction and the width of the conductor layers 47a, 47b is formed narrower than that of the conductor layers 43a, 43b. Even when a pattern of the conductor layers 43a, 43b, and 47a, 47b is deviated in the vertical direction, no capacitance change is caused. Furthermore, when the pattern is deviated in the horizontal direction, if a capacitance Cc1 by the conductor layer 43a is increased, the capacitance Cc2 of the other conductor layer 43b is decreased, resulting that the total capacitance is not changed.

Patent JP-H10332214-A (JP)
Title: Linear compressor
Inventor: FUNATSU YOSHINORI
IPC: F04B35/04
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To improve refrigerating ability by forming a plurality of operating gas passages in a plane perpendicular to an axial direction of first and second cylinders disposed coaxially, thereby upgrading heat radiation. SOLUTION: Since operating gas becoming a high temperature by a compressing operation is transferred to a refrigerating unit 20 and then heat near a coil head 22 is pumped to an operating gas passage side, the heat is stored at this part. Since a plurality of the gas passages 17 are arranged, a contact area between the gas and operating gas passage wall is increased, and hence the heat can be rapidly transferred to the wall to remove the heat stored in the gas. Accordingly, a refrigerating efficiency is improved. Since heat radiating fins 31 are arranged on an outer periphery of the passage part 13, heat transferred from the passages 17 to the part 13 can be rapidly dissipated via the fins 31. Since the heat stored in the passage 13 can be rapidly removed, heat radiation is further improved, and refrigerating efficiency is improved.

Title: Molded winding
Inventor: MAEDA TAKAO
IPC: H01F27/32
Filed: 1988-06-08
Abstract: PURPOSE:To obtain structure having high dielectric strength and easy to be manufactured by using an article formed by impregnating an insulating fiber woven fabric or a nonwoven fabric molded to a wave-form with a molding resin and half curing the resin as an insulating spacer between a low-voltage winding and a high-voltage winding. CONSTITUTION:A low-voltage winding 12 is wound on the outer circumference of an internal insulating layer 8. An insulating spacer 4 in which an insulating fibrous fabric is molded in periodic wave-form irregularities and impregnated with a molding resin and the resin is half cured is wound on the outer circumference of the low-voltage winding 12. A high-voltage winding 2 composed of high-voltage windings 21, 22... is wound outside the spacer 4. The whole is molded by the resin, completely cured and unified. Flexural properties required for winding the insulating spacer 4 on the low-voltage winding 12 by half curing the resin of the insulating spacer 4 and mechanical strength for holding a wave form by winding the high-voltage winding 2 are imparted, thus easily providing a winding. Since one spacer is wound on the whole low-voltage winding 12, the precision of the position of the winding of the spacer may be low.

Title: Tube spinning device
Inventor: NAKAMURA TERUSHIGE
IPC: B21D22/16
Filed: 1981-09-09
Abstract: PURPOSE:To prevent generation of damage on the surface of a mandrel and on the inner peripheral face of a work by connecting the mandrel and tail stock shaft mechanically with rugged parts when starting the work. CONSTITUTION:When starting working, a mandrel 11 and a tail stock shaft 14 are brought close to each other, and a projected part 25 is engaged with a recessed part 26 and these are positioned coaxially. When the mandrel 11 is driven and rotated, rotation is transmitted mechanically to the tail stock shaft 14. Accordingly, the statical force of inertia is not loaded on a work 15 and possibility of generating slipping between the mandrel 11 and the work 15 is eliminated. As rotation similar to that of the mandrel 11 is given to the tail stock shaft 14 by an air motor 20, the frictional resistance between the tail stock shaft and tail stock 13 is cancelled and torque that acts on the work after working also becomes small.

Abstract: PURPOSE:To obtain a paper cutter efficiently cutting a paper roll provided with a spliced part spliced halfway by every image frame. CONSTITUTION:When a paper is carried, the deviation (sigma) of a cut mark or the like is read based on the size information of the image frame and the information of a print mask, the carrying quantity X(A+sigma) of the paper is set and the width of a paper guide is changed(steps 200-204). Next, the paper is carried by a distance X after the cut mark is detected(steps 208-218). Then, the paper is cut and the size of the cut image frame is transmitted to a sorter(steps 220-222). At this time, when the cut mark is detected, a pair of cut marks is detected, both ends of an area including the spliced part are cut and a signal showing unnecessary is transmitted(steps 216, 224 and 226). Therefore, the spliced part of the paper is cut according to a pair of cut marks previously put. Then, the carried-in paper can be ejected by the sorter part.

Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To save the nonvolatile memory of the numerical controller and to facilitate update operation for the software, and to optimize the decentralization of a load to controllers. SOLUTION: When a system is started up, a host computer 2 reads in software modules from an external nonvolatile memory 3 according to a system constitution information file CR and reconstitutes control software for machines, which is transferred to the volatile memories (b) of respective numerical controllers. The software modules are stored altogether in the external nonvolatile memory 3, so when the control software is updated, data of only software modules in the external nonvolatile memory 3 are updated and the operation is made simpler than update operation for control software of the respective numerical controllers. Further, the load can be decentralized to controllers by the same method most efficiently.

Filed: 1983-08-02
Abstract: PURPOSE:To correct properly an increment of acceleration by providing an air fuel sensor for detecting oxygen concentration in exhaust gas of an internal combustion engine and a means for correcting variation ratio in transient running under the specific condition of air fuel ratio. CONSTITUTION:A air fuel ratio sensor detects an amount of oxygen included in exhaust gas.
