An electrically erasable and programmable read only memory device unavoidably creates weak electric field between control electrodes and drain nodes of non-selected floating gate type field effect transistors connected to either selected word or bit line in an erasing/programming operation; however, the direction of the electric field is changed during the erasing/programming operation so as to prevent the non-selected floating gate type field effect transistors from disturbing phenomenon.

A wobble plate type compressor is disclosed which includes a compressor housing having a plurality of cylinders and a crank chamber adjacent the cylinders therein. A reciprocative piston is slidably fitted within each of the cylinders. A drive mechanism is coupled to the pistons. The drive mechanism includes a drive shaft which is rotatably supported in an opening of a front end plate and extends into the compressor housing. The drive shaft is supported by a radial bearing. The drive shaft is attached on to an end surface of a cam rotor at an inclindation angle .theta..sub.1 and rotates therewith. The angle .theta..sub.1 is determined so that under severe operating conditions the interior surface of the radial bearing and the exterior surface of the drive shaft are uniformly contacted with each other to prevent damages due to partial contact. In alternative embodiments, the radial bearing is formed with a conical inner surface to insure uniform contact between it and the exterior surface of the drive shaft.

A sleeve stroke SSt of a specific sleeve is gradually increased from “0” (after t1) in a state in which a vehicle is stopped, a transmission is in a neutral state (all sleeve strokes SSt=0 (original position)), a clutch is in a disengaged state (clutch stroke CSt=0 (original position)), and an engine is operating (engine rotational speed NE>0). Upon determination that the sleeve stroke SSt has reached a predetermined value A, at which synchronization operation of a corresponding synchronization mechanism is performed, the sleeve stroke SSt is fixed to the predetermined value A, and an operation of increasing the clutch stroke CSt from “0” in a press engagement direction is started (time t2). An engagement start point CStlearn of the clutch is obtained based on a change in the rotational speed Ni of an input shaft Ai of the transmission after that (time t3).

The present invention provides an optical recording medium including a substrate and a recording layer on the substrate having a squarylium metal chelate compound with a central metal. The recording layer includes a mixture of squarylium metal chelate compounds having ligands of the same type as well as metals of two or more types as the central metal. It is preferable that the recording layer includes a squarylium metal chelate compound having a bivalent metal as its central metal and a squarylium metal chelate compound having a metal other than a bivalent metal as its central metal.
摘要:
In a parking support device, a distance measuring unit measures a quantity equivalent to a distance from an automotive vehicle to an object existing in a predetermined direction. A storage unit stores a sequence of points indicating results of the measurement performed multiple times. A first object specifying unit generates first object information based on the sequence of points when a length of the sequence of points has exceeded a first reference length. A second object specifying unit generates second object information based on the sequence of points when a length of the sequence of points has exceeded a second, larger reference length. A target parking position is determined based on the first object information in a stage where the first object information is generated.
