Title: Head rest position adjuster
Inventor: TANAKA MASATOSHI
IPC: B60N2/48
Filed: 1993-03-01
Abstract: PURPOSE:To achieve higher effect of reducing damages to a neck part by adjusting a head rest body longitudinally and vertically to the optimum position based on the position of the top of a shoulder determined with first and second distance measuring sensors and an ECU as reference. CONSTITUTION:For example, a relative position of the top of a shoulder is determined with an ECU 5 with respect to a head rest body 6 existing at a reference position known based on distances calculated from the results of detection with both the distance measuring sensors 3 and 4 and infrared irradiation angles of both the sensors 3 and 4. Moreover, the distance is calculated to a point Q corresponding to the top of the shoulder from a reference point P at a lower end of the head rest body 6 to obtain a longitudinal direction component Ld and a vertical Le of the distance between the points P and Q. The rotation of a first motor 9 is transmitted to a rack 8 with gears 11 and 13 to move the rack 8 longitudinally and with the gears 12 and 14, the rotation of a second motor 10 is transmitted to a rack at the lower end part of a support bar 7 to move the support bar 7 vertically. Thus, the head rest body can be adjusted to the optimum position thereby achieving a reduction in damages to a neck part.

IPC: B26F3/02
Filed: 1985-03-29
Abstract: PURPOSE:To enable usability to be augmented by allowing a form to be accurately fitted into a machine by means of knob operation through the medium of a form pressing roller in a burster where the continuous form is cut into each of single forms along the scored line which is made at regular intervals of the stated space. CONSTITUTION:In fitting a form 2 placed on a support table 10, the form is inserted in underneath a form pressing roller 27 which has been separated from a form running plate 25 accompanied with upward retraction of a support frame 37. Subsequently, the support frame 37 is swung downward allowing the form pressing roller 27 to press the form 2 located on the form running plate 25 by a spring (62) force. Then, a slitter 63, form feeding rollers 8 and 9, and form discharging rollers 15 and 16 are rotated with a motor driven, a knob arranged at the end of a rotational shaft 28 is operated so as to rotate the form pressing roller 27 through a one-way clutch (not shown) allowing the form 2 to be forwarded. Subsequently, the form 2 is quickly pulled out by a form discharging roller 15, the circumferential speed of which is higher than that of the form feeding roller 8 and 9. This caused the form to run against a break body 21 permitting the form to be cut off along the lateral scored line.

Title: Deflection circuit
Inventor: IMAIZUMI NORIO
IPC: H04N3/22
Filed: 1988-03-18
Abstract: PURPOSE:To make the picture size in the vertical direction always constant irrespective of high-voltage variation by changing the value of a vertically deflected current by controlling the amplitude of saw tooth waves produced from a saw tooth wave producing circuit in accordance with the variation in the high voltage produced in the anode of a cathode-ray tube by means of a control circuit. CONSTITUTION:When the value of a DC power source +B connected to the primary winding 5 of an FBT 4 varies to a higher value, the wave crest value of FET pulses produced from the high-voltage winding 6 becomes higher and the high voltage applied across the anode 8 of a cathode-ray tube 9 also rises. Moreover, the voltage across the output terminal of a rectifier circuit 10 also rises since the voltage induced in the secondary winding 7 also rises similarly. As a result, a current corresponding to the rise in the voltage across the output terminal of the circuit 10 is supplied to a capacitor 23 and the charging voltage of the capacitor 23 is raised. Accordingly, the amplitude of saw tooth waves becomes larger and the value of the deflection current flowing to a vertical deflection coil 18 also increases, and then, the deflection angle of an electronic beam becomes larger by the rise in the high voltage. Therefore, the picture size in the vertical direction is maintained in a constant state.
