Title: Disk brake
Inventor: KOBAYASHI KINZO
IPC: F16D65/18
Filed: 1994-03-18
Abstract: PURPOSE:To effectively suppress a brake squeak in accordance with its cause by forming a pressing area, different relating to the radial direction of a pad, of at least one piston of a plurality of the pistons against the pad. CONSTITUTION:An internal diameter of an outlet side piston 17a is formed smaller than an internal diameter of an inlet side piston 16a, and depth from an opening end face 19a to a bottom part of the outlet side piston 17a is also formed smaller than depth from an opening end face 18a to a bottom part of the inlet side piston 16a, to form the outlet side piston 17a in thickness larger than the inlet side piston 16a as a whole. An area of the opening end face 19a of the outlet side piston 17a is formed larger than an area of the opening end face 18a of the inlet side piston 16a. A vibration, generated in the end part of a disk rotational direction outlet side of a pad 4 can be reduced by a large pressing area by the outlet side piston 17a, thus to enable a brake squeak, caused by this vibration, to reduce.

Title: Split winding transformer
Inventor: ASAKURA MASAKATSU
IPC: H01F30/00
Filed: 1981-03-31
Abstract: PURPOSE:To achieve a good balance magnetically and electrically in a split winding transformer by arranging a primary winding and a secondary winding symmetrically. CONSTITUTION:A primary winding is separated into two parts H1 and H2 at the centre, which are connected in parallel, and external terminals U and V are led out. Among secondary windings L1, L2, L31 and L32, two windings L1 and L2 are arranged in the vertical direction within the primary winding, and their external terminals 1u, 1v, 2u and 2v are led out. The rest, windings L31 and L32, are connected in parallel in the outer side of the primary winding, and their external terminals 3u and 3v are led out. With such an arrangement, any impedance between every primary winding and every secondary winding can be the same. Further, a load current is fully evenly separated among H1 and H2 windings, so that an abnormal increase of iron loss can be eliminated. In addition, since this transformer is splitted into two parts, the adequate number of sections can be organized, and thus this construction can be applied to a higher-voltage and larger-capacity transformer.

Title: Control device for engine
Inventor: SEO NOBUHIDE
IPC: F02D45/00
Filed: 1992-03-06
Abstract: PURPOSE:To prevent unstabilization of control by limiting changing a control constant when a change of operative condition of an engine exceeds a predetermined value, in the case of feedback-controlling a condition quantity relating to the engine so as to approach a target vague based on the predetermined control constant. CONSTITUTION:In an engine 1, oxygen concentration in exhaust gas is detected by an air-fuel ratio sensor 3 in an exhaust passage 2, thus to control a fuel injection valve 5 by a controller 4 so that air-fuel ratio obtains theoretical air-fuel ratio. A bypass valve 9 is arranged in a bypass passage 8 of a throttle valve 7 in an intake air passage 6, thus to control the bypass valve 9 by the controller 4 so as to maintain an idle rotational speed always optimum. Here in the controller 4, whether a change is provided or not in an operative condition of the engine 1 is detected. When the change of the operative condition exceeds a predetermined value, in response to this change, a change of control constant is limited. In this way, control is prevented from being not stabilized due to diffusion of adaptive control.

Abstract: PURPOSE:To expand data most suitably for high-speed operation to shorten the execution time of a program by transferring data, which are arranged at certain intervals on a main storage device, to an extended storage device by the instruction from a high-speed operation processing device. CONSTITUTION:A high-speed operation processing device 2 sends a data transfer request 100 to an extended storage data transfer processing part 6, and an operation code which indicates a request for data transfer from a main storage device 4 to an extended storage device 5, a start address a on the main storage device 4, data length n of one block unit, an inter-element distance m which indicates intervals of existence of block data to be transferred, a number l of transfer blocks, and a start address on the extended storage device 5 are added to this request 100. The extended storage data transfer processing part 6 reads out desired data from the main storage device 4 by the data transfer request from the high-speed operation processing device 2 and writes this data in the indicated address on the extended storage device 5 at indicated inter- element intervals. Thus, array data is so expanded that high-speed operation is possible, and the execution time of the program is shortened.

Title: Enclosed lead-acid battery
Inventor: HIRONAKA KENSUKE
IPC: H01M10/08
Filed: 1995-03-09
Abstract: PURPOSE: To provide a enclosed lead-acid battery in which stratification of the electrolyte can be prevented without greatly reducing the capacity and enclosed reaction efficiency of the battery. CONSTITUTION: A sulfate of a composition formula MXSO4 (M is a metal element and X is a plus integer) which is slightly soluble to the electrolyte is dispersed and supported in a retainer. Then lead sulfate is negatively charged within the electrolyte. As a result, the sulfate and sulphate ions in the electrolyte repel each other electrostatically, and the sulphate ions become more likely to be dispersed in the electrolyte. Thus the sulphate ions are prevented from accumulating in the bottom of the electrolyte to prevent stratification of the electrolyte.

Abstract: PURPOSE:To secure to form a film excellent in durability by specifying and adjusting the tensile force of a supporting body between respective supporting body convey sections divided with cylindrical cans. CONSTITUTION:The tensile force of a supporting body 10 between the respective supporting body convey sections divided by cylindrical cans 6, 1, 2 and 5 is adjusted so as to fill expressions I and II with respect to a Young's modulus.

The Young's modulus is different at every supporting body convey section due to the classification and the film width of a thin film layer formed in a preprocess. Thus, the supporting body can run at the stable tensile force preferable to cooling, and the thin film with high durability and travelability can be formed.

Title: Control method of air-fuel ratio for internal combustion engine
Inventor: SUZUKI KOZO
IPC: F02D41/00
Filed: 1987-03-05
Abstract: PURPOSE:To prevent the excessive correction of an air-fuel ratio by lengthening a set period with an idling condition detected in a manner wherein the air-fuel ratio is controlled based on an air-fuel ratio correction value which is adjusted at every set period in accordance with the comparative result between an exhaust gas component concentration detected value and a reference value. CONSTITUTION:With an engine 5 operated, in a control circuit 20 an air-fuel ratio correction value is adjusted by an unit volume corresponding to an engine operation parameter in accordance with the comparative result between an oxygen concentration detected value given by an O2 sensor 14 acting as an exhaust gas component concentration sensor and a reference value when an air-fuel ratio feed-back control condition is satisfied. And the air-fuel ratio of mixture is controlled by controlling an air-fuel ratio control means such as a linear type electromagnetic valve 9 and the like based on said air-fuel ratio correction value. In this case, in the control circuit 20 a change is so made that the set period becomes longer when an engine 5 idling is detected. And the change in the air-fuel ratio correction value is thereby delayed in speed so as to prevent the excessive correction of the air-fuel ratio.
