Title: Parallel comparator and element switch having the same
Inventor: NOIRI AKIRA
IPC: G06G7/02
Filed: 1990-10-31
Abstract: PURPOSE:To increase the switching process speed of cells by inputting the header of a cell to be compared by (m) bits at each time from the bits of high- order digits, and comparing and deciding the current output of the input bit sequence. CONSTITUTION:The parallel comparator 6 inputs a 1st and a 2nd bit sequence sent as an (m)-bit parallel signal by (m) bits at each time from the high-order bits in order in synchronism with their synchronizing signals and outputs a comparative decision result at the point of time according to specific priority order if the 1st and 2nd bit sequences are in large/small relation. Further, an element switch 7 receives the large/small comparative decision result of the headers of the inputted cells from the parallel comparator 6 to switch those cells. Consequently, the cells can be processed at a time at a bit rate (m) times as high as that of an element switch 7 which uses a serial comparator.

Title: Region current density controllable led
Inventor: SO HOJO
IPC: H01L33/38
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To provide an LED allowing the region current density to be controlled. SOLUTION: A separate current blocking layer is provided between the front electrode and an LED polycrystalline layer or between the back electrode and the substrate to remove the current of the LED polycrystalline layer down to the bottom side of the front electrode. This prevents the drawback of the transmitted light brightness reduction due to absorption or blocking of emitted lights by the front electrode, and the current blocking layer may be located at an adequately specified position to section a desired light emitting region position relatively from the current distribution circuit, thereby maximizing the light emission brightness efficiency at the specified region. Besides the current blocking layer and the electrodes are formed together after manufacturing the substrate and the LED polycrystalline layer, this makes the manufacture simple and convenient.

Title: Radio communication system and radio communication method
Inventor: ADACHI TSUKASA
IPC: H04W72/04
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To conduct communication of a multi-link access system between a simple master set, having only two radio channels and a plurality of slave sets and to attain outgoing/incoming call control from other slave sets. SOLUTION: When a simple master set 1 and a slave set 2 are conducting 64 kbps high-speed data communication by adopting a multi-link access system, the simple master set 1 monitors the validity of transmission reception data of a radio channel. When invalid data are detected for a prescribed time and no valid data are sent from the slave set 2, the master set 1 uses ancillary control channel in a communication slot of a radio channel 1 to interrupt the radio channel 1. In this case, the slave set 2 manages data of the radio channel 1 in a simulating way so as to avoid out of synchronism and keeps a data frame with received data of the radio channel 2.  Furthermore, a data frame generating section 106 of the simple master set 1 generates data worth two radio channels in a simulating way, so as to avoid out of synchronism due to loss of transmission data to an ISDN channel and transmits the data to the ISDN channel. The simple master set 1 uses the idle channel to transmit the data of the control channel so as to attain outgoing incoming calls to/from other slave sets.

Abstract: PURPOSE:To reduce the warpage and deformation, and to lessen the contraction changing rate of a substrate by a method wherein the substrate is suspended by a jig having a structure with which a part of the substrate supported when it is treated in a heating furnace. CONSTITUTION:The upper side of the substrate 4 such as a square-shaped substrate is fixed by one or more substrate fixing parts 5, and the substrate is suspended. As the tensile stress works on the substrate by its own weight, the generation of deformation by warpage can be reduced. Also, the substrate has a marked tendency of contraction by one heat treatment cycle in general, and as tensile stress works on the whole substrate, the contraction rate of the substrate becomes small. The substrate 4 is constructed in such a manner that a circular hole 9 is provided at two corners of the substrate 4 and it is hung by engaging the hole with the circular projected part 10 provided on a quartz jig 6. The quartz jig 6 has the function in which the wafers are conveyed in front and rear, and left and right directions, but a method in which the quartz jig and the substrate are merely left in a tube may be considered. The substrate is maintained in the state wherein it is hung by the quartz jig while a heat treatment is performed.
