Title: Multi-electrode double layer capacitor
Inventor: DISPENNETTE JOHN M
IPC: H01G15/00
Filed: 1997-08-29
Abstract: A single cell, multi-electrode high performance double layer capacitor includes first (Stack A) and second (Stack B) flat stacks of interleaved electrodes (141) adapted to be housed in a closeable two-part capacitor case (Fig. 12) which includes only a single electrolyte seal (154, 156, 158). Each electrode stack has a plurality of electrodes connected in parallel, with the electrodes of one stack being interleaved with the electrodes of the other stack to form an interleaved stack (141), and with the electrodes of each stack being electrically connected to respective capacitor terminals. A porous separator sleeve (140) is inserted over the electrodes of one stack (Stack B) before interleaving to prevent electrical shorts between the electrodes. The electrodes are made by folding a compressible, low resistance, aluminum-impregnated carbon cloth (136), made from activated carbon fibers, around a current collector foil (132), with a tab (133) of the foils of each electrode of each stack being connected in parallel. The parallel-connected tabs (135, 142) are then connected to the respective capacitor terminals. The height of the interleaved stack is somewhat greater than the inside height of the closed capacitor case, thereby requiring compression of the interleaved electrode stack when placed inside of the case, and thereby maintaining the interleaved electrode stack under modest constant pressure. The closed capacitor case is filled with an electrolytic solution and sealed. A preferred electrolytic solution is made by dissolving an appropriate salt into acetonitrile (CH3CN).  In one embodiment, the two parts of the capacitor case (150, 152) are conductive and function as the capacitor terminals.

Title: Lift cylinder and mast assembly of forklift
Inventor: NAGAI KATSUMI
IPC: B66F9/24
Filed: 1999-04-07
Abstract: An ultrasonic sensor detects whether a piston is at the lowest position. The sensor is not affected by the environment or damaged by contact with other objects. The sensor is located in the bottom of a mast cylinder, transmits ultrasonic waves to the bottom of a piston and receives ultrasonic waves reflected by the piston. The sensor then outputs electric signals based on the received ultrasonic waves. The ultrasonic sensor is electrically connected to a transmitter-receiver, which, in turn, is electrically connected to a controller. The transmitter-receiver includes an ultrasonic wave generator and sends ultrasonic wave transmitting signal having a predetermined frequency to the ultrasonic sensor based on control signals from the controller. The controller measures time from when it outputs the ultrasonic wave transmitting signal to when the sensor receives a reflected wave. The controller then compares the measured time with a threshold value thereby judging whether the piston is at the lowest position.

Title: Cdma base station assisted soft handoff
Inventor: CHENG TERRY SI-FONG
IPC: H04B7/26
Filed: 1999-06-09
Abstract: A code-division multiple access base station assisted quality soft handoff algorithm screens or filters out candidate pilot signals from a pilot strength measurement message generated by a mobile station and provides the revised pilot strength measurement message to the mobile switching center of the mobile communication system. The mobile switching center subsequently conducts handoff processing in accordance with the revised pilot strength measurement message. If the combined pilot signal strength of the existing mobile station active legs is less than a first threshold, the current pilot strength measurement message is maintained. If the combined pilot signal strength of the existing mobile station active legs is greater than or equal to the first threshold, all candidate pilot signals are deleted from the pilot strength measurement message such that only pilot signals of existing mobile station active legs remain. Also, if the pilot signal strength of a candidate pilot signal is greater than a second threshold, the candidate pilot signal is added to the pilot strength measurement message.      The number of handoffs per call are reduced using the revised pilot strength measurement message such that forward link power and network processing resources are conserved.

Abstract: The bonding of cereal straw in the face layer of a composite panel is carried out with urea formaldehyde (UF) resin or melamine urea formaldehyde (MUF) resin in combination with acid. The treatment consists of applying either a strong or weak acid to straw at levels below 10% of the oven-dry (OD) mass. This results in a drop in straw pH  and straw buffering capacity which facilitates the bonding of the straw with OF or MUF in a heated platen press. The treatment allows the straw-based composite panels to achieve properties in excess of commercial standards without using MDI exclusively.  The acid can be applied to the straw at various stages of comminution before panel pressing.
