Title: Resin-impregnated belt for application on papermaking machines and in similar industrial applications
Inventor: DUTT WILLIAM H
IPC: B29D29/00
Filed: 1998-12-11
Granted: 2003-07-01
Abstract: A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base fabric in the form of an endless loop with an inner surface, an outer surface, a machine direction and a cross-machine direction. The base fabric has machine-direction (MD) structural elements and cross-machine-direction (CD) structural elements in an open structure wherein at least some of the MD structural elements and CD structural elements are spaced apart from one another. The MD structural elements cross the CD structural elements at a plurality of crossing points, where they are joined to one another by mechanical, chemical or thermobonding means. A coating of a first polymeric resin is on the inner surface of the base fabric. The first polymeric resin impregnates and renders the base fabric impermeable to liquids, and forms a layer on the inner surface thereof. The coating is smooth and provides the belt with a uniform thickness. A method for manufacturing the belt, using a smooth and polished cylindrical mandrel with a spacer ring slidably disposed thereon, is also shown.

Abstract: To make it possible to accurately detect a pedal depression force even if a pair of rotating members for detecting the pedal depression force are misaligned with each other. In a pedal depression force detecting device for a bicycle designed to transmit a depression force applied to a pedal through an elastic member to a sprocket, first and second magnetic rings 141 and 142 each having a plurality of N poles and S poles alternately arranged are fixed to the pedal and the sprocket, respectively. A first pair of sensors 151a and 151a' for detecting the magnetic poles of the first magnetic ring 141 are located about 180DEG apart from each other, and a second pair of sensors 152a and 152a' for detecting the magnetic poles of the second magnetic ring 142 are located about 180DEG apart from each other. A phase difference between the first and second magnetic rings 141 and 142 is obtained by averaging phase differences obtained by the first and second pairs of sensors. With this configuration, the phase difference between the first and second magnetic rings 141 and 142 can be correctly obtained and the pedal depression force can be accurately detected irrespective of misalignment between the first and second magnetic rings 141 and 142.

IPC: H01L29/201
Filed: 1999-04-20
Granted: 2001-01-01
Abstract: This invention is about the semiconductor light-emitting device. The purpose of this invention is to provide the semiconductor light-emitting device that has decreased action voltage and realizes higher output than before in the InGaAlP semiconductor device series. Due to the installation of the contact layer with the rating amount of carbon, the contact resistance between the contact layer and the ITO electrode can be reduced. In addition, carbon does not diffuse like zinc and there is no concern of deteriorating the device property. From the center bandgap layer set in between the contact layer and the covering layer, the discontinuity of the valence band is buffered so as to enhance the flowing of the positive hole and decrease the device resistance.

Granted: 2001-09-11
Abstract: The present invention is a decoding system for transferring a system stream multiplexing the video stream obtained by compressing and coding the video signal, a presentation time stamp, and a program clock reference for recovering the system time clock of the decoding system, to the CPU through a bus and processing it on the CPU. The entered system stream is stored in first buffer means, and is transferred to second buffer means through the bus. The system stream stored in the second buffer means is read out by the CPU and decoded. The capacity of the second buffer means is set so as to exceed the quantity of the system stream entered in a time necessary for arbitration of transfer requests in the bus. Moreover, the PCR input to the STC recovery means is delayed by the delay time from the output of a packet from a demodulator until arrival at the CPU.

Title: Surface light source device of side light type, liquid crystal display and guide plate
Inventor: YAMAZAKI HIROSHI
IPC: G02F1/1335
Filed: 1999-06-05
Granted: 2001-05-01
Abstract: A liquid crystal display panel is illuminated from the back side by surface light source device of side light type composed of guide plate, primary light source (3) (fluorescent light (7) and reflector), reflecting sheet, and prism used as a light control device. On the illuminative output surface of guide plate scattering pattern and rough area (M) are formed. Scattering pattern is composed of several tiny scattering elements. Rough area (M) is located between scattering elements, and the scattering ability of rough area is weaker than scattering element. The dot type scattering elements are distributed by pre-defined patterns. The pattern can be designed by the required level of illuminative improvement. Not only the scattering elements but also the rough area among them can improve the illumination. Therefore it's hard to generate tiny flicking brightness uneven or glittering. And even though the attachments such as prisms are directly disposed on the output surface, this design also prevents the attachments from sticking on it. The actual roughness range of rough area (M) is about 0.02 to 0.25 mu m.

Title: A single-feed circularly polarized square slot antenna
Inventor: WU JIAN-YI
Filed: 1999-09-18
Granted: 2001-04-21
Abstract: A new design of a circularly polarized printed square slot antenna loaded with a rectangular conducting patch is presented. The rectangular patch is placed along one of the center lines of the square slot. With the selection of proper dimensions of the rectangular patch, circular polarization (CP) radiation can be obtained by using a microstrip feed line oriented along the diagonals of the square slot. The proposed slot antenna has been implemented and experimentally studied. An impedance bandwidth of 39% (determined from 10-dB return loss) and a 3-dB CP bandwidth of 12% (defined by 3-dB axial ratio) for the proposed antenna have been obtained, which is greater than 2 times that of a conventional single-feed circularly polarized printed slot antenna. The gain variation for the frequencies within the CP bandwidth is also observed to be less than 0.9 dB.

Title: Automatic over-clock method for CPU
Inventor: GAU JIN-SHAN
IPC: G06F1/04
Filed: 2000-03-17
Granted: 2003-03-01
Abstract: The present invention relates to an automatic over-clock method for CPU. The method mainly uses a clock generator that allows free frequency adjustment and provides monitoring (watchdog) function, and applies numerical method to find power-on frequency of a computer, so as to accomplish the function of automatic over-clock. If over-clock procedure is entered after a computer is powered on, all the default parameters of previous power-on will be stored and copied first for comparison in the next power-on. Many flags are also set in the present invention for determining the present conditions as bases of the next step. Power-on frequency can be found by, in accordance with numerical method, comparing the first power-on frequency separately with the bus frequency and the highest frequency of the frequency generator. In this way, it only needs a very short time to find the required frequency. The set of parameters are stored after power-on for future power-on application. However, if any system parameter is changed or any hardware accessory is modified, the set of parameters will become ineffective and the function must be re-executed.
