Title: Knocking control device for engine
Inventor: TAWARA YOSHITAKA
IPC: F02D41/14
Filed: 1983-09-16
Abstract: PURPOSE:To control engine knocking with good responsibility while preventing an engine output from being lost and any schock from being produced by correcting ignition timing to permit it to be delayed and an air fuel ratio to permit it to change in its rich direction and thereby returning the ignition timing to an original condition with a prescribed time constant when the engine knocking is produced. CONSTITUTION:The captioned device includes an operation state detecting means comprising a knocking sensor 16 as a knocking angle sensor 17 for detecting an engine operation state and a negative pressure sensor 18. Further, it includes a basic ignition timing determining means for receiving an output from the operation state detecting means to determine the basic ignition timing, and a control circuit 20 having a function serving as an ignition timing correcting means and an air fuel ratio control means for knocking control. The ignition timing correcting means serves to correct the basic ignition timing by a prescribed amount in the direction of an angle to be delayed while serves to allow an engine to be returned with a prescribed time constant after delayed. In addition, the air-fuel ratio control means controls an air fuel ratio of mixed gas in the rich direction by a prescribed amount at generation of knocking and returns the air-fuel ratio to an original value after the ignition timing is returned.

Title: Device for converting resolution of picture
Inventor: DAIMON MASAHIRO
IPC: H04N1/387
Filed: 1990-06-29
Abstract: PURPOSE:To obtain a desired picture element density conversion performance with comparatively simple circuit constitution by adding a couple of black picture elements whose size is 1/4 to a linked part of a conversion picture when there is arrangement of independent black picture elements in the oblique direction in a picture inputted to a resolution converter. CONSTITUTION:An input picture element data I is a binarized serial picture element data for, e.g. a facsimile equipment sent through a telephone line or the like. Four picture elements (2 rows X 2 columns) data I1-I4 adjacent to each other in upper/lower/ right/left directions are obtained simultaneously from the input and the output of picture element buffers 10, 12. Conversion picture element data O1-O4 form high density print picture elements of 2 rows X 2 columns being four divisions of one of input picture elements. The 2X2 print picture elements are placed in the middle of the input picture elements I1-I4. When diagonal picture elements among the four input picture elements adjacent to each other in upper/lower/right/left directions are a black picture element and a white picture element, a converted picture with high resolution with less roughness is obtained with comparatively simple circuit constitution by converting the data into a picture element data with four-times picture element density in which four picture elements in upper/lower/right/left directions are all at black level.

Title: Power tool
Inventor: UEDA TAKASHI
IPC: B25B23/157
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To enable one-operation switch of a clutch and a drill by providing each engagement part at inside surfaces of an internal gear and a gear case, providing connecting members fitting, inserting and connecting into/with each engagement part in an insertable/detachable state and suppressing the operation of the internal gear by fitting and inserting the connecting members. SOLUTION: When a mode is set to a drill mode, an internal gear 8 related to a clutch operation obtains a sure drill mode, even if large load is applied to an output shaft 21, because the internal gear 8 is surely fixed and power can be transmitted without operating a clutch because an engagement part provided on a side surface of a connecting member 11 engaged and fixed with/to an engagement part provided on a gear case 5 and an engagement part provided on a side surface of the internal gear 12 are engaged. Because constraints on dimensional accuracy of parts and deformation are mitigated, cost reduction of parts can be contrived. Further, because a switch of a clutch mode and the drill mode can be performed with one operation, regardless of locations of a cap, workability can be improved.

Title: Magnetic head
Inventor: AMANO SAICHIROU
IPC: G11B5/105
Filed: 1981-10-30
Abstract: PURPOSE:To ensure the satisfactory hardening of the resin on a tape rubbing surface without deteriorating the characteristics of a magnetic core, by using a resin material having both the optical hardening properties and the thermosetting properties to the resin part which is exposed to the tape rubbing surface. CONSTITUTION:The resin having both the optical hardening properties and the thermosetting properties is implanted up to an area l of a resin part 2 which is exposed to a tape rubbing surface. Then the resin which is implanted from the tape rubbing surface side outside a main body case 1 and by irradiation PR of the light of an ultraviolet lamp, etc. is hardened, and the thermosetting resin is implanted to the 2nd burying resin implanting part 9. Then the case 1 is put into a thermostatic chamber to be held at a thermosetting temperature. Thus the whole part is hardened by heat. For instance, the resin of the level of 300 of the ''3-bond'' is used to the resin in this example to suppress the occurrence of stress down to a comparatively low level to avoid the deterioration of a magnetic core for the heat hardened part by selecting the hardening conditions. As a result, a satisfactory level of hardness is secured for a surface layer which is formed by an optical hardening process.
