Abstract: A stator device which prevents the formation of varnish accumulations on jumper wires, thereby preventing jumper wire breakage due to temperature variations. A gap is created between the jumper wire and the stud located on the stator body. When varnish is applied to the stud and the jumper wires, excess varnish flows through the gap and pools underneath. Moreover, when there is a significant accumulation of varnish in the gap, the varnish will flow off from the edge of the stator body.

Abstract: A method and apparatus for image forming includes a hybrid developing apparatus that supplies surly charged toner to a developing roll. The apparatus includes a developing roll that is electrically conductive at least on its surface. The image forming apparatus and the method have a constitution capable of applying an alternating current bias having a duty ratio in the range of 10 to 50% and a direct current bias superposed thereon. The developing roll is directly confronted with a latent image bearing body through an insulative toner thin layer at the nearest region of the developing roll and the latent image bearing body. An independent bias is applied to each of the developing roll and the magnetic roll, and the toner is refreshed by the varying duty ratio of the alternate current bias and the direct current bias after developing.

Abstract: The retainer of the present invention is made of a composite material having a body made from a polymer, a layer of solid lubricant formed over the body by chemically coating the body with a porous layer of solid lubricant and impregnating the solid lubricant with another lubricant using conventional methods such as vacuum impregnation. The retainer is placed between an outer raceway and an inner raceway to form a self-lubricating bearing. The bearing made in this manner has high lubrication tolerance (i.e. it performs well in the absence of external lubrication). Because of its high lubrication tolerance, the bearing is suitable for use in various applications such as dental/medical hand pieces that are periodically sterilized and other applications which occasionally experience periods of lubrication starvation.

The keyboard switch is configured in a pantograph structure having cross arms that intersect each other to form an X-like structure. The upper portion of the pantograph structure is movably attached to a coupling plate on the underside of the keytop and the lower portion of the structure is movably attached to a base plate so as provide the keytop with movement in the vertical direction. The keyboard switch has two frame members that each have two cross arms that are parallel and fixed relative to each other.

Abstract: The first amplifier circuit D1 is formed by connecting drains of a pair of N-channel MOS transistors forming the first current mirror circuit CM1 respectively to the drains of P-channel MOS transistors 1 and 2 as a differential input portion, and the second amplifier circuit D2 is formed by connecting drains of a pair of P-channel MOS transistors forming the second current mirror circuit CM2 respectively to the drains of N-channel MOS transistors 5 and 6 as a differential amplifier circuit. The first and second differential amplifier circuits D1 and D2 can amplify the first and second signals having cycles corresponding with each other with their duty ratios kept unchanged regardless of their operating point potentials. Further, the two outputs are combined into one output to suppress variation of the operating point potential of the output attributable to process-related factors, fluctuation of the power supply potential due to the oscillating operation and the like.

Abstract: A key switch stabilizer mechanism having a first approximately C-shaped stabilizer wire which is connected to both a key top and a base plate, and is further supported so as to be able to turn with respect to the key top; and a second stabilizer wire having a flat portion connected to the base plate, a bent portion, and another flat portion connected to the key top. Therefore, touching even very lightly any part of the key top surface, in particular the top end peripheral edge, allows a pushing pressure to be imparted to the first and second wires arrayed within the key top, by means of which a membrane push mechanism operates. When pressure on the key top is released, the first and second stabilizer wires follow the reaction force from the membrane switch push mechanism and rise, such that the membrane switch can be operated.

Abstract: This low profile key switch structure provides a substantial reduction in the height or thickness of a key switch as compared to conventional and other low profile switches. Substantial height reduction in key switch structures allows the size and thickness of notebook-type personal computers and the like to be similarly reduced. One feature of this low profile key switch structure is that unlike in conventional key switch structures the membrane switch and frame structures do not over lap to cause unnecessary height in the structure. Another feature of this key switch structure is that the frames are formed to include the free motion range limiters. The frames are further formed so that they may be embedded in the reinforcing base plate in such a manner that allows the height of the key switch to be further reduced. This low profile key switch structure is also designed to eliminate unwanted key top movement that often occurs in conventional and other switches when the key top is depressed.

Abstract: A power converter having a transformer with a primary side winding and a secondary side winding, each having a switch. When the primary master switch is switched on, the transformer charges. When it is switched off, the intrinsic capacitance of the secondary slave switch discharges generating the zero voltage switching condition for the secondary slave switch. The secondary slave switch is switched on at a time determined in accordance with the waveform generated by the transformer. When the secondary slave switch is switched on, the transformer discharges and ultimately the charge from an output capacitor flows into the transformer as a backflow which charges the transformer. The secondary slave switch is switched off at a time determined in accordance with a current flowing through said secondary switch. The intrinsic capacitance of primary master switch discharges generating the zero voltage switching condition for primary master switch which is then switched on.
