Filed: 1992-04-24
Abstract: PURPOSE:To prevent a person sitting at the rear seat from laterally moving and increase safety by pushing forward arm arm-rest body to function as a shoulder pad in case of side crash of a car. CONSTITUTION:When an arm-rest is not used, the front end of a hook 11 drops in a hook hole 15 to fit to it and, as a result, the arm-rest body 9 is unified with a support frame 4.

Title: Apparatus for preventing opening of signal converter output circuit
Inventor: AMANO TAKAYOSHI
IPC: G01D3/08
Filed: 1985-05-20
Abstract: PURPOSE:To make it possible to prevent the opening of an output circuit by increasing the number of measuring machineries connectable to a signal converter in series, by selecting a thyristor having a proper limit resistor. CONSTITUTION:When measuring machinery 5 is detached because of disconnection or checking, overvoltage is applied to both terminals of a thyristor 13 because the current proportional to quantity 1 to be measured is ready to flow by a signal converter 2. At this time, a gate current is made to flow in the gate of the thyristor 13 through a limit resistor 12 by the voltages at both terminals of the thyristor 13. The thyristor 13 is brought to a continuity state by said gate current and the open of a circuit due to the disconnection or detachment of the measuring machinery 5 is prevented and the output signal of the signal converter 2 can be normally supplied to he other measuring machinery 5 connected to the signal converter 2 through the thyristor 13. By this method, the number of measuring machineries connectable to the output circuit of the signal converter and the opening of the output circuit can be prevented without lowering measuring accuracy.

Title: Optical pickup device
Inventor: HIRAYAMA NAOYUKI
IPC: G11B19/20
Filed: 1983-06-14
Abstract: PURPOSE:To eliminate the use of an automatic controller for focusing direction and to realize the reduction of cost as well as a compact design of an optical pickup device, by shifting a disk with revolutions by holding the disk between two pairs of upper and lower roller guides. CONSTITUTION:The light beam delivered from a semiconductor laser 1 is focused to a disk 8 through an objective 7 after passing through a beam splitter 3 and a 1/4 wavelength plate 6. The reflected light sent from the disk 8 travels adversely an optical path and is reflected again by the splitter 3 to be condensed to a photodetector 5. Two pairs of upper and lower roller guides 14 are set to hold a place where the light beam on the disk 8 is focused. These guides 14 are positioned so that the disk 8 is sent to a focused point. Therefore it is possible to eliminate the planar deflection at the area where the light beam is focused to the disk 8 by shifting with revolutions the disk 8 by means of the guides 14. This eliminates the use of an automatic controller for focusing direction.
