Title: Centralized radio communication system
Inventor: YAGETA KOICHI
IPC: H04J13/00
Filed: 1993-06-30
Abstract: PURPOSE:To improve the transmission efficiency by decreasing number of acknowledge packets sent/received when data are sent from a base station to slave stations by the centralized radio communication system. CONSTITUTION:A data reception instruction code is sent from a base station to slave stations (No.1). When the preparation of reception of data is finished, each slave station sends a reception ready (packet) to he base station (No.2). The base station sends plural packets to the slave stations simultaneously. The base station sends a transmission data end signal after the end of transmission. Each slave station checks an error of the received data and generates acknowledge packets (ACK, NAK data strings) informing the success/failure of the transmission packet in the order of transmission of data packets (No.3). Each slave station sends the acknowledge packets to be generated to the base station. After the base station receives the acknowledge packet from all the slave stations, the base station calculates OR of the ACK, NAK from N-sets of the slave sets for M-sets of data packets (No.4). The packet specified by the OR calculation is sent to a slave station having a reception error.

Title: Hydraulic pressure feeding system for booster, and hydraulic pressure type booster
Inventor: ISHIWATARI ICHIRO
IPC: B60T13/12
Filed: 1994-07-16
Abstract: PURPOSE:To prevent the generation of the malfunction even if a liquid pressure sensor is installed in close to a booster device, by forming a throtle for drawing a flow passage in comparison with the flo passage area on a hydraulic pressure source side, in the passage leading from the liquid pressure sensor to a servopiston inside. CONSTITUTION:The orifice 7500 of an orifice member 750 midway in a pressure intrducing passage has a diameter of 0.2mm or so, and the min. flow passage area is formed in the passage leading to the inside of a booster 100 through the pressure introducing passage from a hydraulic pressure source 300. Accordingly, even if the pressure lowering is generated inside the cylinder body 140 of the booster 100, by the sharp operation of the booster 100, the large lowering of the pressure at the part 136a is prevented, and the pressure becomes the value of the pressurized liquid inside an accumulator 320. Accordingly, so far as no pressure loss is generated on the liquid pressure source 300 side, a hydraulic pressure sensor 600 supends the switching operation, and malfunction can be surely prevented.
