Title: Fluoropolymer laminated separator plate
Inventor: ROCHE ROBERT P
IPC: H01M8/02
Filed: 1993-12-23
Abstract: Electrolyte migrates inter-cell in fuel cell stacks due to an electric potential gradient across the stack. This migration can be substantially inhibited with a graphite separator plate which has been laminated to the electrolyte reservoir plates of adjacent fuel cells with a fluoropolymer resin. In such an arrangement, the fluoropolymer resin forms an electrolyte barrier between the graphite separator plate while maintaining an electrically conductive pathway between the electrolyte reservoir plate and the graphite separator plate.

Abstract: A disposable air filter is described including a filter element (24) formed from a stacked plurality of annular disks (25). The disks (25) are formed from a sorptive material and expand upon absorption of oil or water droplets. The disks (25) are slightly compressed by a movable baffle (28). The baffle (28) floats upon a stream of air entering the filter and directs the air radially through the filter element (24). The air flows between and through the disks (25) with a resulting low pressure drop across the filter. As the disks (25) expand, the baffle (28) shifts axially within a filter housing (11) to maintain the pressure drop across the filter element.

Abstract: A golf club head has a head (110) and a shaft (111) defining an axis, the head having a heel (113), a toe, a top (114) and a bottom (115). Connection of the shaft to the head involves a socket (112) associated with the head, the socket having inner wall structure (117) extending in the direction of the axis, and with annular wall portions (118-120) relatively angled at axially successive locations in the direction, at least one of the wall portions (119) providing a locally camming surface. The shaft has a lower end portion (111a) forcibly received endwise into the socket (112) and collapsed at least in part toward the axis in response to its forcible reception in the socket, and against the camming surface. The wall structure (117) forms with the shaft lower end portion (111a) a clearance (150, 150a) axially offset from the camming surface (119) for reception of adhesive which is thereafter caused to cure and adhere the shaft lower end portion to the wall structure.

Abstract: A method for forming silicon integrated circuits is disclosed. Ion implantation of polysilicon gates is accomplished by directing a dopant species (21) at a polysilicon layer (19) at an angle instead of normal incidence. The angularly directed dopant species cannot channel through the polysilicon layer and, furthermore, the dopant species "sees" a thicker effective polysilicon layer (19).

Abstract: A control device suitable for use in a sing-along or karaoke apparatus has a rotary encoder coupled to a selector knob through a transfer mechanism, such as gears. When the selector knob rotates, the rotary encoder generates pulse signals for each rotation of the selector knob. The number of pulses may depend upon a gear ratio of the transfer mechanism. The control device is used, for example, to scan and select music titles stored in a ROM cartridge or other suitable storage medium. The control device may be integrated with an apparatus for controlling the start or stop function. The control device provides a design flexibility due to its compact design.

Abstract: An excess current protection system (17,37,38,32,35) for GTO electronic power converters which upon the occurrence of an excess current limited in its rate of increase by an inductor (9), instantaneously inhibits the firing of the quenched GTOs and controls quenching of the fired GTOs immediately or with a delay, thereby ensuring that this takes place with a predetermined delay after their firing less than the minimum firing interval necessary for discharge of the excess voltage limiters associated with the GTOs. 
     The system automatically resets itself if the current ceases to be in excess, and stops the operation of the converter after a predetermined number of interventions within a predetermined time interval.

Abstract: An energy efficient logic gate circuit (11,12) design that provides a substantially constant load to a clock source (Φ 1 , Φ 2 ) regardless of logic signal inputs (IN 1  -            IN     ¯             1  IN 2  -            IN     ¯             2 ) to, or outputs from, the gate. The gate provides two complementary outputs (OUT 1,             OUT     ¯             1,  OUT 2,             OUT     ¯             2 ) and utilizes cross-coupled transistors (17,18) to ensure that the outputs remain valid (complementary) after the logic inputs become invalid. Two logic blocks (15,16), each having a node coupling to the clock source and performing complementary logic functions, in combination with diodes (26,27) for recharging the outputs of the gate, present the constant load to the clock source.

Abstract: Coding gain is improved by employing an N-dimensional trellis encoder incorporating an N'-dimensional convolutional encoder where N' is less than N. The additional coding gain is realized as a shaping gain. This unique modulator encodes a digital signal by generating a sequence of N-dimensional symbols as a function of the digital signal using an N'-dimensional convolutional encoder within the trellis encoder more than once (integer N/N' times) during each N-dimensional symbol interval. This allows the trellis encoder to produce an output of higher dimensionality than would normally be expected from the lower dimensionality convolutional encoder. The trellis encoder is applicable to television transmission.

Abstract: The system comprising a controller fitted to a subject vehicle (16) and sensor means (20) operable to sense a distance of separation and relative velocity of a trailing vehicle (18). Also input to the controller is a velocity signal derived from a velocity sensing means (97) determining the ground speed of the subject vehicle using a doppler radar system. The controller calculates a safety envelope and activates a visible warning device attached to the rear of the subject vehicle if the trailing vehicle penetrates the safety envelope. An enhanced safety envelope determined by adverse road conditions is also established, any incursion into the enhanced envelope resulting generally in the visible warning being at a less prominent level. If however the closing speed of the trailing vehicle exceeds a predetermined threshold, penetration of the enhanced envelope results immediately in the full warning being displayed with full prominence to the driver of the trailing vehicle. The system has application to improving the safety of road vehicles.

Abstract: A radio-frequency amplifier circuit of simple construction having low power consumption and low heat generation, and which amplifies an input signal while maintaining composite triple beat (CTB) distortion, amplitude type cross modulation distortion, and phase type cross modulation distortion at a minimum, is provided. The radio-frequency amplifier comprises a transformer which transforms an input signal from an unbalanced state to a balanced state. The amplifier further comprises at least one distortion generation circuit including a first circuit having a nonlinear element and a first delay line coupled in series, and a second circuit having an attenuation element and a second delay line coupled in series. The first and second circuits are coupled in parallel. At least one distortion generation circuit is coupled to an input, an output, and/or an intermediate point of a radio-frequency amplification stage of the radio-frequency amplifier. The first and second delay lines are configured to create a delay time change in a signal input level of a signal input to the radio-frequency amplification stage which opposes a delay time change in the signal input level caused by a delay time difference between the input and output of the radio-frequency amplification stage. A transformer transforms the amplified input signal from the balanced state back to an unbalanced state before outputting the amplified signal from the amplifier circuit.

Abstract: The method is carried out in an engine esp. a four cylinder piston engine with individual cylinder isolation. With the analysis of the rpm, the overall rpm signal of the engine, regarding the duration of at least one working cycle of the engine, is split up to give individual cylinder contributions, so that indirectly an isolated observation of the ignition pressure rpm of each individual cylinder is obtained. The ignition pressure RPM (nKSZBZ) of any selected reference cylinder (BZ) is individually compared with the ignition pressure rpm (nKSZZyl) of each other cylinder. The difference between the two ignition pressure RPMs to each other is determined.
