Abstract: PURPOSE:To carry out the car body incline control in the passing time on a curved line without delay, by comparing the curve radius calculated from the relative rotation displacement between a car body and an under carriage, and the running position of the car depending on the running distance; with the curve radius and the curve position of the railroad data; and correcting the running position of the car by making the differences as the correcting amount. CONSTITUTION:Between a car body 4 and an under carriage 5, a displacement meter 1 to detect the relative rotation displacement between the car body and the under carriage by the boggy of the under carriage is provided, and its detecting signal 6 is input to a controller 2. On the other hand, the pulse signal 7 of a speed generator 3 provided to the wheel shaft is input to the controller 2.

IPC: G05D23/20
Filed: 1985-02-08
Abstract: PURPOSE:To improve the accuracy of a temperature control by using a crystal oscilla- tor whose oscillation frequency by a reverberation effect is varied sharply by a temperature, as a temperature sensor. CONSTITUTION:A crystal oscillator 1 having a large reverberation effect is provided on the side wall of an enclosed rotary vessel 2, and a signal corresponding to an oscillation frequency by the reverberation effect of this oscillator 1 is detected by a frequency detecting means 8.

When a temperature is detected by this crystal oscillator, a high frequency feeble electric signal is transmit ted from a transmitting means 6 by a power source part 4 which is controlled by the control part 3 of a centralized managing room. The crystal oscillator 1 is resonated with it through a receiving means 6, and after a prescribed time, the transmitting signal is halted and a damping oscillation is continued. As a result, the oscillation frequency is varied sharply by a temperature, and it is detected by the detecting means 8.

Title: Laser device
Inventor: TAKAHASHI NORIO
IPC: H01S3/22
Filed: 1980-02-22
Abstract: PURPOSE:To make it possible to obtain laser output in a matter of several seconds even if a laser power source is switched on in the darkness, by connecting in parallel the xenon discharge tube and a condenser to an output terminal of a laser tube. CONSTITUTION:A positive pole of a trigger circuit 13 of a laser power source 1 is connected to an anode 3 of a laser tube 2. A positive and a negative pole of a direct current power source circuit 14 is connected respectively to an electrode 9' of a xenon discharge tube 8 and an electrode 9 of the discharge tube 8 and cathode of the laser tube. A condenser 7 is connected to the discharge tube 8 in parallel. In this formation when the laser power source 1 is switched on in the darkness, the laser tube 2 does not start discharging in an instant. On the other hand, because the voltage at the start of the discharging to the discharge tube is lower than one to the laser tube 2, the delay in discharge starting is short, and as soon as the required voltage is reached the discharge starts in an instant. Electric charge on the condenser 7 is turned to discharge current of the discharge tube 8 generating a flash. This flash, on touching on the cathode, urges to discharge. Thus discharging starts between the anode 3 of the laser tube 2 and the cathode in a matter of several seconds.

Abstract: PURPOSE:To prevent any increase in excessive fuel by setting a narrow fuel increase quantity correction range for a fuel correction coefficient map used for controlling an air-fuel ratio during constant operation. CONSTITUTION:A basic fuel injection quantity Tp is calculated in a circuit 3 from an intake quantity Qz and rotational speed Ne of an engine detected by sensors 1, 2, and a fuel correction coefficient KMR is set in setting device 4a, 4b from the basic fuel injection quantity and the engine rotational speed Ne based on a fuel correction coefficient map including a wide increase quantity correction range, and the fuel correction coefficient map including a narrow one. A changeover switch 6 responds to a speed change ratio Gp detected by a sensor 7, and a corrected coefficient from the setting device 4b is selected in the case of the speed change ratio on the high speed side, and a correction coefficient from the setting device 4a is selected in the case of the other side. The basic correction injection quantity Tp is corrected by the selected correction coefficient in a correction device 5 so as to determine the fuel injection quantity Ti. It is thus possible to prevent such an event as a quantity increasing direction is determined in the same way as the case of acceleration requirement with the speed change ratio on the high speed side where fuel consumption is considered significant.

When internal pressure becomes low, the right valve operates in the same way, and air goes into the disk chamber 2 through a filter 18 for filtering dust and a moisture absorbing agent 17. In this way, damage of the internal device and the housing is prevented.

Filed: 1989-01-31
Abstract: PURPOSE:To improve a photoelectric conversion device of this design in the accuracy of temperature compensation by a method wherein a bypass resistive component is formed of an amorphous semiconductor layer sandwiched between two laminated bodies. CONSTITUTION:A resistive component 6 in an amorphous semiconductor layer 3 composed of an I-type amorphous silicon semiconductor layer 7 and an I-N junction which are interposed between a transparent conductive film 2 and a metal terminal 8 and grows to be a resistive component which varies in resistivity corresponding to light rays incident from a substrate side. The resistive component 6 is formed in such a state that it decreases in resistivity corresponding to the change of an incident light volume, and the change of an output voltage to the change of an incident light volume becomes small but a temperature coefficient can be minimized in incident light volume dependence. By this setup, the temperature coefficient of a photoelectric conversion element of this design can be made small and a temperature compensation of higher accuracy in a wide range can be realized.
