Title: Ultra high frequency circuit and its static electricity protecting method
Inventor: USHIYAMA KATSUMI
IPC: H01P1/00
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To protect an ultra high frequency circuit in a semi-millimetric wave band and a millimetric wave band from a static electricity surge. SOLUTION: In this static electricity protecting method, one ends (point A and point B) of microstrip lines L2, L3 of λ/4 in length which are connected with the input end and the output end of a circuit 10 to be protected are connected with a power source and ground through diodes CR1, CR2 and diodes CR3, CR4, respectively. These diodes are connected in the inverse polarity of DC. Accordingly, the points A and B are connected through capacitors C2 and C3 in high frequencies. The stray capacitances of the diodes CR1-CR4 are connected in parallel with the capacitors C2, C3 in high frequencies, so that influence is little. The microstrip lines of λ/4 long have high impedance in high frequencies, so that the circuit 10 to be protected is scarcely affected by the diode connection. On the other hand, surge is absorbed by the diodes and the circuit 10 is protected.

Filed: 1988-02-26
Abstract: PURPOSE:To obtain an apparatus capable of receiving and supplying a plate piece in a short time by disposing a pair of right and left conveyers which can be connected to a line and are adapted to support both side portions of the plate piece in such a manner as to separate above a stock portion where plate pieces are placed, and providing means for transferring the plate piece in the substantially vertical direction between the stock portion and the conveyers. CONSTITUTION:A suction pad 4 of a sucking cylinder 5 is lowered to suck the corner portion of a board (a) and raised. At this time, right and left belt conveyers 3, 3 are separated from each other by an air cylinder 25, so that there is no obstacle to passing the board (a) between the conveyers 3, 3. The board (a) is lowered by the sucking cylinder 5 and placed on the belt conveyers 3, 3 approaching the position supporting both side portions of the board (a). After that, the belt conveyers 3 carry out the board (a) to a line (b). In case of receiving the board (a) from the line (b), the above operation is reversed. Thus, the plate piece can be received and supplied in a short time, and an apparatus with a small installation area can be attained.

Title: Data communication system
Inventor: KUSANO MASAAKI
IPC: H04L12/70
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To attain data communication with high throughput performance by allowing a data transmitter to send an information frame with a re- transmission number added thereto in addition to a sequence number and allowing a receiver to make a re-transmission request when a re-transmission number of an information frame this time differs from that at a preceding time. SOLUTION: Upon the receipt of a re-transmission request frame REJ 38a, a data transmitter increments a re-transmission number RSND by 1 into RSND=1 and transmits information frames DATA 37d, 37e, 37f with RSND=1 after N(S)=5 again sequentially. In the case that there is any error in the DATA 37d again, the receiver receives the DATA 37e and detects a sequence error, compares the RSND with a value in a re-transmission detection table 39, updates the value in the re-transmission detection table 39 into '1' and sends a re-transmission request frame REJ 38b. The receiver receives succeedingly the DATA 37f, where the RSND is '1' and equal to the value of the re-transmission detection table 39. Thus, the data transmitter sets the RSND to 2 and transmits information frames DATA 37g, 37h, 37i with RSND=2 after N(S)=5 again sequentially.
