Patent EP-0462848-A2 (EP)
Inventor: KEANE VINCENT JOSEPH
IPC: B60T11/22
Filed: 1988-04-26
Abstract: An actuator for a fluid pressure system includes a foot pedal (50) pivotally connected to a support structure (51) for movement away from and into a rest position. A piston-cylinder assembly (2) has a piston (9) slidably mounted within a bore (8) of a cylinder member (3) and a pressure chamber (14) formed at least in part within said member. Movement of said piston in one direction relative to said member is operable to cause a reduction in the volumetric size of said chamber. The assembly (2) is pivotally connected to the foot pedal and the support structure respectively, and the pivotal connection to the foot pedal is located intermediate the ends of a lever forming part of the foot pedal. The two pivotable connections with the support structure are spaced apart so that movement of said pedal away from said rest position causes movement of said piston in the one direction.

Abstract: A diffuser employing a purely phase volume holographic medium recorded with scattering boundaries defining smoothly varying changes in the refractive index of the medium arid providing increased optical path lengths for light traveling through the diffuser is disclosed. The scattering boundaries in the thick volume holographic medium are characterized by the absence of sharp boundaries or lines which would tend to abruptly change the direction and intensity of light passing through the medium. The smooth or gradual boundaries or regions of the material defined by smoothly varying changes in the refractive index cause the medium to act like a GRIN medium and the behavior of the medium can be explained using the GRIN model. The purely phase GRIN type medium scatters all light incident the medium and no significant reflection of light incident thereon occurs. Consequently, the diffuser causes light passing through it to travel in a random, curved and lengthened optical path which greatly improves its diffusing characteristics.

IPC: H01L29/792

Abstract: A flash EEPROM is produced comprising multiple MOS cells. In each cell, programming and erasing are performed through tunneling from the write gate (22) to the floating gate (14) and by tunneling from the floating gate to the erase gate (10), respectively. The directional dielectric employed is a multilayered structured (MLS) oxide (16), where thin oxide and thin polycrystalline silicon form alternating layers. The layering is asymmetric: that is, either the uppermost or bottommost layer is thicker than the other layers. As a result of this structure, the oxide exhibits directionality, that is, the tunneling is easier in one direction than the reverse direction, and significantly enhances the tunneling phenomena (tunneling current can be observed at as low as 4.7V). In addition, the MLS oxide can be fabricated having different dielectric constants. The directionality, coupled with the separate write and erase gates, gives the new flash EEPROM cell a number of advantages: it is low-voltage operable, it is highly resistant to disturbance and has an easily scalable structure (that is, it can be made to operate at any given voltage within a specified scale).

IPC: H02M1/00
Filed: 1993-06-22
Abstract: In critically continuous boost converters used to achieve high power factor and low input current harmonic distortion, a power FET is driven by a pulse generator whose on time is essentially constant over a single line cycle. Off time is terminated when current in the inductor falls to zero and the voltage on the side of the inductor not connected to the input voltage is less that the input voltage. A delay causes turn on to occur at the minimum of the voltage ring to minimize turn on switching losses. At voltages when the input voltage is less than one half of the output voltage part of the on time, turn on occurs with negative current flowing through the FET power switch and the inductor. Part of the turn on time is used to charge the inductor current back to zero before energy can begin to flow back into the output of the converter. A correction circuit is provided which extends the on time as a function of the input and output voltage to avoid dead time around the zero voltage crossover.

Abstract: The quality of both a gate oxide and a tunnel oxide in a P-well active area of a CMOS EEPROM process is improved by reducing the field edge pullback arising from wet chemical etch steps prior to the growth of the gate and tunnel oxides. A first oxide is grown, and an implant is performed through the first oxide to form an implanted layer. The surface of the first oxide is then cleaned without removing all of the first oxide overlying the implanted layer. An anneal step then activates the implanted layer to form a heavily-doped region, after which the remaining first oxide is then removed. A second oxide is then grown, and a region of the second oxide is removed overlying the heavily-doped region. Lastly, a tunnel oxide is grown over the heavily-doped region while re-oxidizing the second oxide to form a gate oxide thicker than the tunnel oxide.

Abstract: For swivelling lamellar plates (3.1, 3.2), a scalene articulated rectangle (4.1, 6.1, 8.1, 6.2) is used, the first side of which is formed on a stationary support (4.1). The third side (8.1) of the articulated rectangle, which lies opposite the first side, defines the swivelling angle of the plate (3.1) which is connected firmly to it. In order that the swivelling mechanism is self-closing even in the case of a vertical lamellar front, the plate (3.1) is, with the aid of a distance element (8), connected to the swivelling side (8.1) at a given minimum distance therefrom. As a result, a torque generated by the dead weight of the plate (3.1) acts on the swivellable side (8.1) of the articulated rectangle, which torque guarantees the self-closing. <IMAGE>
