Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce costs by simplifying arithmetic operations with the accuracy of estimation kept intact via filter processing offering a yaw rate gain expressed basically as a yaw rate divided by a steering angle. SOLUTION: For controlling a brake actuator 4, a vehicle motion controller 5 estimates a vehicle yaw rate gain from detection values by a steering angle sensor 1, vehicle speed sensor 2 and yaw rate sensor 3, and computes a braking force command value for each wheel that keeps the yaw rate gain estimate no longer deviating from a target yaw rate gain. Steering angle filtering operation means are provided to subject the steering angle detection value to filter processing.

Title: Gas flow detecting apparatus
Inventor: GOTANDA MOTOHIRO
IPC: G01P13/00
Filed: 1988-10-20
Abstract: PURPOSE:To detect the stream of gas accurately by displaying the flowing of the gas in correspondence with the difference between gas pressures at an inlet port and an outlet port when the gas pressure at the outlet port is slightly decreased with respect to the gas pressure at the inlet port. CONSTITUTION:When the pilot frame of a gas device is ignited, the gas pressure at the side of an outlet port 46 and the inside of a diaphragm 54 is decreased. Therefore, the diaphragm 54 pushes a compressing spring 55 and shrinks owing to the high gas pressure at the side of an inlet port 45. Then a movable lid 51 and a movable shaft 50 are lifted together with a movable body 53 which is in close contact with a packing 52. A lower washer 58 comes to contact with the lower surface of a fixed plate 48 by the lifting of the movable shaft 50. Therefore, the lifting of the movable shaft 50 is stopped. Thus a permanent magnet 31 is lifted by the lifting of the movable shaft 50 and approaches a reed switch 32. The reed switch 32 is turned ON, and an idicating lamp 33 of a display part 34 is lit. Thus, the fact that the gas is being used is detected.

IPC: F02P3/08
Filed: 1989-10-11
Abstract: PURPOSE:To reduce the start rotating speed and obtain sufficient ignition performance over the whole rotating speed region by providing the first and second trigger signal feed circuits feeding trigger signals at the position where the short circuit current of an exciter coil reaches a peak and at the position with the more advanced phase than that. CONSTITUTION:A trigger signal is fed to a cutoff control switch 26 at the position where the short circuit current of an exciter coil 1 reaches a peak when an engine is rotated at a low speed, thus the short circuit current of the exciter coil 1 is cut off at the low rotating speed, the voltage for charging a capacitor is induced, and the start rotating speed can be reduced. When the rotating speed exceeds the preset valve and the cutoff value of the short circuit current becomes sufficiently high, the cutoff value is fixed, thus the cutoff valve of the short circuit current never becomes insufficient. The energy generated by the exciter coil 1 is fully utilized over the whole rotating speed region, sufficient energy can be stored in an ignition energy storing capacitor 4, and sufficient ignition performance can be obtained over the whole rotating speed region of the engine.

Abstract: PURPOSE:To make it possible to improve noise absorption effect, reduce the noise, and change the flow passage with ease by providing a space and a shutter which are extended from a ventilation fan mounting section by a specified dimension inside a casing. CONSTITUTION:An indoor air is sucked up from a ventilation duct 23 by way of a space 15 and discharged outdoors by way of the ventilation duct 23 as indicated in the arrow by driving a blower of a ventilation fan main body 16. During this operation, an acoustic material 22 mounted in the space 15 absorbs the noise generated by the blower 21.
