Title: Tire inflation pressure detecting device
Inventor: TOMINAGA MOTONORI
IPC: B60K28/16
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy for detecting a tire air pressure state during driving in which a slipping state varies according to fluctuation of the driving power of the vehicle. SOLUTION: An arithmetic processing unit 2 in a tire air pressure detecting device uses a rotating-state-value computing means 2b to compute, from the wheel speed detected by wheel speed sensors 1a to 1d, a rotating state value that depends on the deviation of the wheel speed, and uses a front-and-rear wheel speed deviation computing means 2c to compute the wheel speed deviation between the front and rear wheels. From the rotating state values obtained within a predetermined period, data obtained when the wheel speed difference between the front and rear wheels is small in terms of the relative magnitude of the wheel speed deviation are sorted out by sorting means 2d, 2e, 2f.  By setting judging means 2i, 2j so that the air pressure states of tires are judged according to the central value of the rotating state values sorted out, data obtained when a slip state is great is prevented from adversely affecting judgment even if driving power fluctuates.

Abstract: PROBLEM TO BE SOLVED: To significantly prolong the life of a fluid-heating apparatus by forming fluid inlet and outlet ports in a pipe for heating a fluid, disposing a heating element within the pipe, and providing an impurity filter in the fluid outlet port of the pipe. SOLUTION: A particle-removing filter 2 is disposed within a particle container 1, and an exhaust-gas inlet port 3 and an exhaust-gas outlet port 4 are formed in a fluid-heating apparatus 5. An enlarged cylindrical portion 12 is formed at a fluid outlet port 9b of the cylindrical pipe 9 which has a heating wire 10 disposed therein. An impurity filter 13 is inserted into the enlarged cylindrical portion 12. Air discharged by a blower 6 is heated within the cylindrical pipe 9 by the heat of the heating wire 10, and also heated by the filter 13. While heat generation by the heating wire 10 is discontinued, an exhaust gas containing impurities 14 does not flow into the pipe 9 from the fluid outlet port 9b of the pipe 9.  Thus, disconnection of the wire resulting from abnormal combustion, and exfoliation of a protective oxide film due to its reduction can be prevented, whereby the life of the fluid-heating apparatus can be prolonged.
