Title: Vibration detection system
Inventor: TASHIRO HIDEO
IPC: G08B21/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To exactly transmit vibration detection data to a distant place even when a vibration detecting cable is installed long by mutually connecting the vibration detecting cables through a repeater circuit for each block and performing data processing to signals inputted from the vibration detecting cables at the respective repeater circuits. SOLUTION: Vibration detecting cables 3 are arranged while being mutually serially connected through repeater circuits 4 installed for each block. When a signal is inputted from the vibration detecting cable 3 in the 1st block, a discrimination circuit 11 inside the repeater circuit 4 observes the waveform of signal from the vibration detecting cable 3 in the 1st block so as to discriminate whether this signal is inputted by any invading action or simply by wind. In this case, the repeater circuit 4 changes the transmission style of data for specifying the block of invading action so as to transmit these data.

Abstract: PURPOSE:To make the catalytic activation of an exhaust emission controlling catalytic converter yet accelerable. CONSTITUTION:In an exhaust emission control device 1 of an internal combustion engine, a specified flow of gas is made to flow in by an engine 11 or a gas feeding means and an exhaust pipe 3 toward a honeycomb 17 from the side of a heater 15 in addition to heating of this honeycomb 17 or carrier of a catalytic converter by the heater 15 or the heating means till the detection temperature of a catalytic sensor 19 or the temperature detecting means is reached to the specified time or specified temperature before starting and/or after starting the engine 11 at a time when the catalytic converter 5 is activated.

Title: Pneumatic tire
Inventor: FUKUSHIMA HIROSHIGE
IPC: B60C3/00
Filed: 1992-11-04
Abstract: PURPOSE:To reduce the flexure of a belt layer in a tire formed in the crown part with an annular recess having the wide width by hardly reducing the cross- sectional area of the annular recess in filling the internal pressure. CONSTITUTION:Since the thermal contraction rate of cords located near inflection points J, K in a reinforcing layer 43 is enlarged, large tension is generated only in the cords during vulcanization molding and remains even after the vulcanization. Thus, when a tire 11 is filled with the internal pressure, only cords having large remaining tension get difficult to extend so that the circumferential rigidity is improved and the bulging of the annular recess 35 is restrained to a practical value. Also, since the reinforcing layer 43 covers a belt layer 29 over the whole width, an amount of the belt layer 29 thrusted in is uniformed as a whole to reduce the flexure.
