摘要:
An electronic control apparatus that performs feedback control on a fuel injection command value to make an air-fuel ratio come to match a target air-fuel ratio increase-corrects an intake air amount and retard-corrects an ignition timing, together with decrease-correcting the fuel injection command value in the feedback control, and then performs an abnormality detection of a fuel system based on a retard-correction amount of the ignition timing at that time.

It is determined whether a short-run rule can be adapted into a position, where a via cell is parallel and adjacent to a portion of wiring or another via cell. The via cell and the portion of the wiring is arrayed at the smallest space in the wiring. When determined that the short-run rule can be adapted thereinto, via cell data is created. The via cell data includes a via margin which is so reduced in size that the via margin can be equal to or larger than the wiring minimum space. With the created via cell data, automatic layout and wiring is performed. The via cell data is replaced with art-work data including a via cell with an original via margin, so as to be output.

A knocking control apparatus for an internal combustion engine, which is applied to an internal combustion engine including a variable valve mechanism that can vary a valve characteristic of at least one of an intake valve and an exhaust valve, and which changes an engine control amount based on a result of a knocking determination as to whether knocking occurs, includes a controller which performs the knocking determination as to whether knocking occurs based on an output signal from a knock sensor that detects a vibration occurring in the internal combustion engine, and which changes a mode of the knocking determination according to a change in a combustion state of an air-fuel mixture, the change being caused by a change in the valve characteristic.

A memory card installing device has a memory card installing portion that includes a connector. The installing device also includes a lid for opening and closing the memory card installing portion and a connector cover for covering the connector when the memory card is not installed in a predetermined position and the lid is closed.
摘要:
There is disclosed a polyphenylene sulfide resin composition which comprises: (a) 100 parts by weight of a polyphenylene sulfide resin; and (b) from about 0.1 to about 10 parts by weight of finely divided calcium carbonate having a mean particle size of less than about 0.5 .mu.m and a BET surface area of greater than about 15 m.sup.2 /g. The resin composition is improved in that it exhibits no or little corrosive action on metals and that it shows excellent mechanical strength.

A process for producing a polyphenylene sulfide ketone polymer comprising reacting a dihalogen compound of the general formula ##STR1## wherein X and X', which may be the same or different, each represents a fluorine, chlorine, bromine or iodine atom, with an alkali metal sulfide in a polar solvent in such a way that the alkali metal sulfide is not deprived of free water or the water of hydration in the polar solvent before polymerization is started, and that the reaction is performed at a temperature in the range of from 80.degree. to 170.degree. C. in the initial period of polymerization until the percentage of residual unreacted dihalogen compound is reduced to 2% or below, with the subsequent reaction being performed at a temperature in the range of from 200.degree. to 345.degree. C.
摘要:
A ceramic electronic component which comprises a generally elongated ceramic body and a metal cap mounted on each end of the ceramic body. Each end of the ceramic body has a peripheral edge rounded to have a predetermined first radius of rounding, and the metal cap has an interior corner rounded to have a predetermined second radius of rounding. The first radius of rounding is greater than the second radius of rounding.

A tape cassette is provided with a pair of guide rollers for limiting the position of travel in the vertical direction. Holes which serve to determine the position of the tape cassette and into which cassette guides arranged on a chassis of tape recorder can be inserted are formed, respectively, under their corresponding guide rollers. The horizontal distance between the position determining hole and the corresponding guide roller is reduced to a minimum.

This invention is for a tape cassette having window for insertion of a magnetic head and a pinch roller formed extending from a peripheral wall of the housing of the tape cassette to one of the holding plates which holds a pair of reel hubs in place. The device according to this invention has a shutter member, and a resilient metal wire housed in the housing. The shutter member has projections which are to be engaged with an engaging member provided on a tape cassette holder member of the magnetic tape transport apparatus. The metal wire urges the shutter member to close a portion of the window formed in the holding plate. When the cassette is loaded into the loading member, the projections engage with the engaging member and the shutter member releases the closing state of the holding plate forming portion of the window against an urging force of the wire. When the cassette is removed from the loading member, the shutter member closes the holding plate forming portion to prevent the tape from being damaged by an external force.
摘要:
First and second capstans are rotated at respective speeds by first and second motors. The speeds of revolution of the first and second motors are detected as detection signals, and the revolution speed of at least one of the first and second motors is controlled in accordance with a difference between the detection signals. An offset voltage is added to one of the detection signals corresponding to the revolution speeds of the first and second motors for the control of tape tension.
