Abstract: PURPOSE:To enable a sure control operation even in the case of transmitting a code by using IR rays by transmitting the code corresponding to remaining time at the set time and a code to urge the control operation when the time comes to a main control section from a remote controller. CONSTITUTION:A computing means 13 computes the remaining time by the set time and the present time of a clock means 11 when the time is set by a setting means 12 of the remote controller 10. The remaining time is then coded by a code forming means 14 and is transmitted via a transmission means 15 to the main control section 20. The control section 20 sets the timer time of a timer means 22 according to the code upon receipt of said code in a receiving means 21. The code to urge the control generated by the means 14 according to the signal for the reach of the set time by the means 13 is received in the means 13. A control means 23 is started in accordance with the OR of this code and the time-up signal of the means 22. The sure control operation is carried out by the combination of the above-mentioned two systems even in the case of transmitting the code by using IR rays. The reliability of the wireless remote control system is thus improved.

Title: Semiconductor acceleration sensor with driving part for self-diagnosis
Inventor: TANIGUCHI NAOHIRO
IPC: G01P21/00
Filed: 1992-05-26
Abstract: PURPOSE:To make it possible to perform the self-diagnosis as to whether a sensor performs the normal function or not by arranging an electrode, which is approximately in parallel with at least one surface of an overlapped part, applying a voltage across the overlapped part and the electrode so as to impart electrostatic force to the overlapped part, making it possible to drive the overlapped part with static electricity, and obtaining the state, wherein acceleration is applied on the overlapped part in the simulated pattern. CONSTITUTION:An electrode 6 is arranged at the surface of an upper substrate 8 that is bonded to the upper part of a semiconductor substrate 1. The surface faces an overlapped part 2. The electrode 6 is arranged approximately in parallel with the overlapped part 2. When the self-diagnosis of a semiconductor acceleration sensor is performed, a voltage pulse is applied across the electrode 6 and the overlapped part 2. When the voltage is present between the electrode 6 and the overlapped part 2, electrostatic force is generated in the direction for attracting the overlapped part 2 and the electrode 6 in an electrostatic-force acting part F. Thus, the overlapped part 2 is deflected. Therefore, the resistance value of a piezoelectric resistor is changed. The overlapped part 2 acts as if the acceleration G is applied. Whether the acceleration sensor is normally operated or not can be judged by checking the output from the sensor.

Abstract: PURPOSE:To provide a safety device that performs an optimum fail-safe process according to a trouble part, in a control system which is provided with a means for detecting a yaw motion, varying a desired slip factor according to the detected value, and performs antiskid control. CONSTITUTION:At the time of trouble in a yaw sensor or acceleration sensors 11a, 11b, a first fail-safe mode keeping each desired slip factor of wheels 1a-1d constant, not resting on yaw momentum is selected, and such antiskid control as independent of an output of the yaw sensor. In brief, the antiskid control that has set the desired slip factor down to fixation is performed, through which brakability and stability equal to the conventional control are ensured. On the other hand, at the time of trouble in control valves 5a-5d and so on, the antiskid itself is carried out and a second fail-safe mode is selected. In this case, each wheel is lible to be locked, but a no brake state due to trouble in the control valve is thus avoidable.

Abstract: PROBLEM TO BE SOLVED: To stabilize a molding shape and to stabilize the pitch between optical fibers by integrally coating two single core cords with a synthetic resin in the state of holding tension members adjacent to each other to a ribbon form. SOLUTION: The two-core coated optical fiber ribbon T1 is circular in a sectional shape. FRP rods R1 are placed longitudinally along optical fibers (f) and are coated in this state with a UV resin, by which the single core cords C1 , C2 are formed.
