摘要： PURPOSE:To set a switch that is frequently operated at the most easy-to-operate position by setting and changing optionally the corresponding relation between the switch and an electrical parts. CONSTITUTION:A driver puts an ID card 17 where an information pattern is written to designate the corresponding relation between his/her easy-to-operate switch and an electrical parts into a reading device 16. A CPU 1 reads the information on the card 17 through the device 16 and actuates the electrical parts according to the information pattern when the switch is applied. Thus the driver writes the information designating his/her desired switch corresponding relation onto the card 17 and then puts this card into the device 16. So that the correspondence is secured between each switch provided on a vehicle and his/her desired electrical parts. Thus the operability is improved at the driver side and at the same time the specifications can be unified at the maker side respectively.

摘要： PURPOSE:To stabilize the operation of a meter pointer during the OFF period of an ignition switch, by prohibiting the action of a driving section when either a power source voltage or a control signal voltage drops below a specified value. CONSTITUTION:This meter is made up of a control section 1 which generates a signal varying with a specified function characteristic according to changes of an input signal (e.g. vehicle speed signal) and a driving section 2 which controls the direction of forming a magnetic field of a cross coil 3 by regulating the current supply direction and supply current value with respect to the cross coil 3 based on the signal. To run current to the cross coil 3 in both directions, normal and opposite, the driving section 2 has a so-called H switch type circuit composed of current driving type transistors (Tr) 20-25. Then, the Trs 21 and 24 are so arranged to perform the function as operation prohibition means and the operation limit voltage thereof is set, for example, above 2V. This blocks the reception of any signal to forbid the operation of the driving section 2 when the power source voltage or an output voltage of the control section 1 are below 2V.

摘要： PURPOSE:To enhance the recognition property of an alarm car speed, by performing the change-over display of the alarm car speed set in place of car speed data on a speedometer at the setting time of the alarm car speed. CONSTITUTION:Setting switches 1a-1d for setting an alarm car speed on the basis of '0' and '1' codes and a set/reset switch 1e for setting and resetting the alarm car speed are provided in a switch module 1 setting the alarm car speed. The signals from the switches 1a-1e and the car speed signal (a) from a car speed sensor are inputted to a control module 2 and the output of the module 2 is given to a chime 3 and a speedometer 4. The module 2 compares the set value of the alarm car speed set in the module 1 with the actual car speed on the signal (a) and, when both of them coincide, the chime 3 is driven to emit a car speed alarm and, when the switch 1e of the module 1 is subjected to set operation, the set value of the alarm car speed is subjected to change-over display on the speedometer 4 in place of the car speed. By this method, the recognition property of the set display of the alarm car speed can be enhanced to a large extent.

摘要： PURPOSE:To obtain the control pressure of good responsiveness and stability by feeding a pressurized fluid to the primary pressure chamber of a booster for a brake mechanism and concurrently controlling a servo motor. CONSTITUTION:In an initial operation stage, a plunger 24 is quickly actuated on a fluid pressure working on a primary piston 65 due to solenoid valves 73 and 74. Thereafter, the control of the plunger 24 is transferred to a servo motor 68. On the other hand, pressure in a control pressure chamber 6 is introduced into a secondary pressure chamber 53 through a control passage 34, thereby actuating the plunger 24 upward against a pressing force by an elastic body 59. And when the plunger 24 has been moved upward, pressurized fluid in the control passage is discharged from a discharge passage 40. As a result, pressure within the control pressure chamber 6 is regulated to the pressing force of the elastic body 59 corresponding to the fall amount of the primary piston 65 as caused by the servo motor 68, or a level corresponding to an input caused on an input shaft 8.

摘要： PURPOSE:To sense any failure of ignition at a high level of precision by detecting secondary voltage of a current discharged for a certain period after the discharging is started, comparing the voltage with a reference voltage and providing a detecting means which detects a failure of ignition on account of contaminatation thereof due to carbon etc. CONSTITUTION:A high voltage V2 which is applied to an ignition plug 1 is regenerated as a positive output v'2 via an attenuator 3 and an inverter buffer 4. On the other hand, a signal SIG which drives an ignition coil electrifying power switch triggers a mono-stable multivibrator 8 via an inverter 6 and a delay circuit 7 of 50mus, generates a pulse signal SC of a specified time width. An analog switch 5 is kept on for the time width and generates an input signal v'2 as a signal SS. A comparing circuit 10 compares the signal SS with a refer ence signal SR fed from a reference signal generating circuit 9. In case of SS>SR, a signal S0 is generated so that failure of ignition caused by contamina tion of an ignition plug or other reasons can be detected without any possibility of misdetection.

摘要： PURPOSE:To destroy the carbon in a combustion chamber by fire to be removed, by arranging an electrode plate facing to the combustion chamber and providing a means which applies high voltage in a period while combustion gas exists in the combustion chamber. CONSTITUTION:A ring-shaped conductive plate 17, being embedded in the internal wall of a cylinder liner 16, is connected with a high voltage generating device 19 by an electrode terminal 18. A voltage application timing control device 19c sets a period that voltage is applied to the electrode terminal 18 on the basis of a fuel injection pressure sensor 19a and a crank sensor 19b. A high voltage generating circuit 19d generates the high voltage to be output only for the application period set by the control device 19c. In this way, the improvement of output and fuel consumption is promoted because a fine particle of carbon or the like can be prevented from cohesion and destroyed by fire in a combustion chamber.

摘要： PURPOSE:To attain FM reception in an excellent way by eliminating a multipath noise when either of the reduction in a receiving electric field or the generation of echo distortion is detected. CONSTITUTION:When a multi-path reception occurs on both antennas 1A, 1B, an electric field reduction detecting circuit 12 outputs a detecting signal according to the reduction in the electric field level, and an echo distortion detecting circuit 13 outputs a detecting signal according to the generation of echo distortion to control respectively a high cut control circuit 15 and a high blend control circuit 17 via an OR gate 14 so that the noise due to attenuation of the high frequency component of an FM detecting signal is suppressed, the opposite phase component due to the mixing of the high-frequency component of a stereophonic signal is calcelled and the multi-path noise due to the reduction of separation is suppressed. When the reduction in electric field does not reach the operating level of the noise reduction and only the echo distortion is generated or vice versa, the noise is eliminated similarly and the multi-path noise is eliminated completely.
