Title: Adaptive equalizer
Inventor: KUWABARA HIROTO
IPC: H04B3/06
Filed: 1989-04-07
Abstract: PURPOSE:To find the position of a filter coefficient and a coefficient value at a quasi-optimum level without increasing a computing quantity so much by providing an inverse matrix arithmetic circuit and a tap arithmetic circuit. CONSTITUTION:The inverse matrix arithmetic circuit 3 calculates the inverse matrix of a sampling correlation matrix setting an input signal Xk and a training signal (k) from an input register 2 as input, and the tap arithmetic circuit 4 updates and outputs the position and the value of the filter coefficient that is not 0 identically setting the inverse matrix of the sampling correlation matrix from the inverse matrix arithmetic circuit 3 as input. And a coefficient register 6 outputs the filter coefficient to a finite impulse response filter 1 which equalizes and outputs the input signal Xk. In such a way, it is possible to perform desired equalization with a few number of taps even when an impulse response is extended, and to reply to all kinds of transfer characteristics without increasing the computing quantity so much.

Title: Retaining device of plate-shaped body
Inventor: WATANABE KAZUYUKI
IPC: H01L21/68
Filed: 1990-04-03
Abstract: PURPOSE:To enable adhesion of a foreign object to be reduced while retaining a rotary body uniformly by providing a plurality of projecting parts which contact a rear surface of a plate-shaped body in dot shape on a surface for retaining the rotary body for retaining a rear surface of the plate-shaped body at the rotary body which can be rotated by vacuum sucking. CONSTITUTION:For retaining a plate-shaped body (for example a wafer) at a retaining device, a plate-shaped body which is carried by a carrying device (such as a handler) is placed on a sucking surface 3 and then a vacuum pump is operated to allow a negative pressure to be produced at a vacuum hole 4, thus causing a rear surface of the wafer to be held at a suction surface side 3 and a wafer to he fixed to a rotary body 1 while a contact surface 8 of a protruding part 2 is pressed on the rear surface of the wafer. At this time, a space is formed around a contact surface 8. Since this space communicates with the vacuum hole 4, vacuum suction force is uniformly given to the rear surface of the wafer. Then, since a surface area at a tip (peak) of a protruding part 2 is small, entire contact area for the wafer can be reduced to, for example, 1/8 as compared before and the amount of adhering foreign objects can also be reduced to 1/8.

Title: High speed packet coupling network
Inventor: OBARA HITOSHI
Filed: 1987-04-14
Abstract: PURPOSE:To eliminate the need for a control circuit arranged centralizingly to an output terminal by arranging simple control circuits for the preservation of the sequence of packets decentralizingly in each node in a switch. CONSTITUTION:A logic channel number is discriminated at the first half nodes and a packet belonging to its logic channel is sent alternately to an output link. As a result, the flow of one logic channel is distributed impartially in the central node (at a 3rd stage). Although the logic channel of the latter half 3rd and succeeding stages is routed toward an output multiplex link subjected to multiplexing, nodes at a 4th and succeeding stages discriminate a logic channel number and a packet with a smaller packet order is sent to the output link with priority. As a result, the packet order of the logic channel is preserved at the output terminal.
