Abstract: PURPOSE:To reduce the deterioration of image resolution for a picture converting element, by writing the picture information into a picture converting element having a crystal and then reading out the picture information by means of a polarizing element or a photodetecting element. CONSTITUTION:A picture converting element 1 includes a crystal 2, transparent insulated layers 3 and 4 which are provided outside the crystal 2 plus electrodes 5 and 6 provided outside the layers 3 and 4. The voltage is applied between the electrodes 5 and 6 by a power supply 7, and the electric charge is stored at each electrode to obtain a potential slope at the crystal 2. The light sent from the picture information passes through a lens 9 and is formed into an image on a microchannel plate 20 to be converted into a photoelectric element. This element actuates a fluorescent matter 19 to emit the light and is stored in the crystal 2 via an optical fiber. Then the light passed through a polarizing element 11 is irradiated on the surface of the crystal 2 and then reflected by a dichroic mirror 13. This reflected light passes through the crystal 2 again and then through a photodetecting element. Thus the picture information recorded to the crystal 2 can be extracted after being converted into a light image 22.

Abstract: PROBLEM TO BE SOLVED: To linearly control an illumination brightness and simplify a circuit, by A/D, D/A conversion of direct current signal corresponding to the duty cycle of a rheostat signal and by processing data by software. SOLUTION: A rheostat signal 3, for its duty cycle control, is converted to a direct current by passing it through a rectifying circuit 5, and becomes as half voltage as the maximum voltage at point A. This direct current voltage is converted to digital by an A/D converter 6a of a control micro-computer 6, and data are processed by a system controller 6b and transmitted to a system control device 4 of a system sound equipment. At the same time, the direction current voltage corresponding to each illumination load is outputted through a D/A converter 6c, 6d, and amplified to the voltage suitable for each illumination load by a voltage amplifier 7. The output of the converter 6c, 6d is amplified, and the voltage from which a loss due to the current amplifier 9, 10 is subtracted is applied to the illumination load directly, so the that a switching circuit for controlling on/off for illumination is unnecessary.

Abstract: PURPOSE:To make it possible to check the wiring state of a plug socket by using a tester, which is constituted of the grounding terminal of the plug socket, three lamps connected between two voltage terminals and a voltmeter connected to the voltage terminals. CONSTITUTION:A plug 2, which connects pins A-C and a tester main body 2, is inserted into a plug socket 3 of a power feeding single-phase power supply 4. When the wiring connection of the plug socket 3 is normal, the potential differences arc generated between terminals (b) and (c) and terminals (b) and (a), and the potential difference is not generated between (a) and (c). Therefore, lamps L-1 and L-2 are lit, and L-3 is not lit. The potential differences between the terminals (a) and (b) and the terminals (b) and (c) can be measured with a voltmeter 5. When only the lamp L-1 is not lit, it is found that a grounding phase K is wired reversely. When all three lamps are lit, it is found that a grounding terminal (c) is not grounded. When the voltage terminal is not connected, the potential difference is not generated between the terminals (b) and (a). Therefore, all lamps are not lit. Thus, the checking can be simply conducted.

Title: Suspension
Inventor: OKAJIMA KENZOU
IPC: B62D55/104
Filed: 1980-01-19
Abstract: PURPOSE: To minimize the size of the suspension and to save the mounting space thereof on the vehicle body by arranging a rod and a damper in parallel.  
     CONSTITUTION: When a steering arm 32 rotates through a bearing 31, the rod 22 moves circularly in the same direction. This circular motion is transmitted to a pair of upper and lower axle brackets 4 and 35. The axle bracket 35 transmits the motion it receives to an outer tube 6 in the same direction. The outer tube 6, then, transmits the motion to the axle bracket 4 through an engagement between an engaging groove (b) provided in the lower end of the outer tube 6 and a bolt 21 fixed to the bracket 4. The axle bracket 4 is mounted with a sled 3 through a bracket 5 and a shaft 5a. Therefore, the motion is transmitted to the sled 3 so as to change the direction of the sled 3 by an amount and in a direction corresponding to the steering angle. Since the sled 3 is interposed in a body frame, the shock from the sled 3 can be absorbed by a damper 2. Further, since the damper 2 is interposed between the vehicle body 1 and the sled 3, the damper 2 can have a stroke of a sufficient length and also works as a rigidity member.
