Filed: 1983-09-13
Abstract: PURPOSE:To prevent an error in vehicle height detection due to noise by interrupting the detection when an ultrasonic signal which exceeds a specific level is received within a certain time except an expected propagation delay time. CONSTITUTION:An ultrasonic wave from a transmitter 3 which is driven by the output of an oscillator 1 is projected upon the ground surface 7 and its reflected wave is received by a receiver 5. The output of this receiver 5 is detected and smoothed 11, and then compared with a reference voltage Vr by a comparing circuit 15. The output of the comparing circuit 15 is supplied to an AND circuit 29, and the output of the oscillator 1 is also inputted to the AND circuit 29 through a delay circuit 27 with a delay time tau'. If a noise larger than the reference voltage Vr is mixed through the receiver 5 at this time, the AND circuit 29 generates an output. A latch circuit 31 is reset with its output to interrupt the detection of vehicle height H. Thus, an error in the detection due to a noise is prevented.

IPC: G03B17/28
Filed: 1981-10-20
Abstract: PURPOSE:To permit the correction of the inclination of a film leader even when such a film of which only the tongue part is drawn out from a patrone is  used by providing a regulating member for the tongue part of a half width in  the preceding end part of the film leader which is movable into and out from  the plane where the film leader part passes. CONSTITUTION:When a patrone is loaded in a patrone loading chamber 5, a movable arm 28 is moved rightward by a detecting member 34 pressed by the end part of the patrone. In accordance with said movement, a regulating member 20 for the top edge of a tongue part projects into the space between the rear surface 7 of a camera body 2 and an outer guiding member 15 as shown by an alternate long and two-short dashes line. In such a case in which a short film leader extended from the patrone through a slit 8 is drawn out inclinedly downward from the draw-out port, the top end face 20a of the member 20 abuts on the leader part and corrects the inclination thereof. When a rear cover 4 is closed thereafter, a releasing member 21 for the regulation is pushed leftward by the projecting part 23 of said cover, and the member 20 is retreated from the position where the member abuts on the leader part.

Title: Optical pickup head device
Inventor: KADOWAKI SHINICHI
IPC: G11B7/123
Filed: 1990-06-26
Abstract: PURPOSE:To improve mass-productivity while relaxing accuracy for fitting a reflection part by forming first and second reflection parts at the same supporting body so that the fitting error of the first and second reflection parts can be the relatively same angle error. CONSTITUTION:On the same supporting body 15, first and second reflection parts 13 and 14 are formed to reflect laser beams. Therefore, the deviation of an optical axis, which is generated by the error of an angle fitting the first reflection part 13 when the laser beam emitted from a light source 1 is reflected at the first reflection part 13, is canceled when the beam is reflected at the second reflection part 14 to be fitted while including the relatively same angle error as the first reflection part 13. Then, the optical axis of the laser beam emitted from the light source 1 can be made coincident with the optical axis of an objective lens 8 without being affected by the angle of fitting the supporting body 15 forming the first and second reflection parts 13 and 14. Thus, in the case of assembling the optical pickup head device, the productivity is improved while sharply relaxing the accuracy of the angle to fit the supporting body 15 forming the first and second reflection parts 13 and 14.
