Title: Dry-type capacitor
Inventor: MUKAI SADAYOSHI
IPC: H01G4/22
Filed: 1987-12-12
Abstract: PURPOSE:To prevent the generation of cracks when the resin to be used for impregnation is hardened, and to enhance the withstand voltage characteristics of the title capacitor by a method wherein the resin for impregnation, formed by mixing the hardening agent of the blending quantity of 50-80% of epoxy equivalent, is impregnated into a capacitor element and it is hardened. CONSTITUTION:A capacitor element 5 is formed by superposing a dielectric member 1 and an electrode member 2, and by winding around them a number of times. The impregnating resin 8, formed by mixing the hardening agent of the blending quantity of 50-80% in epoxy equivalent into epoxy resin, is impregnated into the element 5, and it is hardened. As the resin 8 remains in the state wherein a part of epoxy radical is unreacted, no cracks are generated when the resin is hardened. As a result, withstand voltage characteristics can be enhanced.

Abstract: PURPOSE:To allow a request side to confirm whether or not intended transmission is implemented by sending destination information including a relay request source in the case of making relay request and informing the end of relay of a succeeding station to a preceding station based on the destination information. CONSTITUTION:When a relay request reception section 20 receives a relay request from a preceding station at a terminal equipment and it is discriminated that its own station is not a final station, a relay request transmission section 50 makes relay request to a succeeding station on request. In this case, the terminal equipment stores the received destination information to a destination information storage section 30 and a relay request transmission section 50 sends the information to each succeeding station. On the other hand, a relay end confirmation section 70 confirms the presence of notice of a relay end from all succeeding stations to which the relay request transmission section 50 makes a relay request by referencing the destination information storage section 30 and informs it to a relay end notice section 40. When the relay end notice section 40 discriminates it that its own station is not a final relay station, the section 40 references the destination information storage section 30 to inform the end of relay of its own station to a preceding station.

Title: Initial catching circuit and phase recognizing method for spreading code, and receiver, in spread spectrum communication
Inventor: NAWA TOSHIHIKO
IPC: H04B1/7077
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To surely acquire an intermediate frequency(IF) and a spreading code in a short time through a sequential search system while using a circuit and method for judging the overlap of search code. SOLUTION: An IF circuit 1 generates a demodulation signal by mixing an IF signal frequency-converted from a radio frequency band with an IF carrier wave. An inverse spreading circuit 2 finds the value of correlation between the demodulation signal and a pseudo random code outputted from a sequential search circuit 3 and discriminates whether both the signal and the code can be correlated or not. In the case of NO, the operations of search code overlap discriminating circuit 4 and frequency update control circuit 6 are enabled. Then, when a code update time counter 4 or a frame & chip counter 5 counts a prescribed value, the update of frequency is instructed to the frequency update control circuit 6.  This operation is continued until the initial value of spreading code is detected by the inverse spreading circuit 2 and afterwards, inverse spreading data are outputted from the inverse spreading circuit 2 while synchronizing the demodulation signal.
