Title: Light chopper
Inventor: UDA YOSHIHIRO
IPC: G02F1/13
Filed: 1979-08-06
Abstract: PURPOSE: To obviate the use of motors and rotary plates, miniaturize the chopper and reduce its driving power by periodically changing the reflectance or transmittance of light of a liquid crystal thereby entering the light into the crystal.  
     CONSTITUTION: Since a multivibrator 32 using an integrated circuit as a driving circuit is connected to a liquid crystal 31, the liquid crystal 31 periodically repeats a transparent state and an opaque state. On the other hand, a light signal 33 is led from an optical fiber 34 via a lens 35 into the liquid crystal 31; when the liquid crystal 31 is transparent, the light transmits through the liquid crystal 31 and when opaque, it is reflected by the liquid crystal surface and enters a photodetector 37 via a lens 36. This results in that at this time the light entering the photodetector 37 is periodically chopped.

Title: Distance measuring apparatus
Inventor: KURODA TOSHIHIKO
IPC: G01S15/18
Filed: 1979-08-08
Abstract: PURPOSE:To accomplish accurate measurement of the distance between relatively small two objects by receiving the time lag of reflected ultrasonic waves emitted from a transmitter with pulselike intermittent waves produced through shaping of continuous waves. CONSTITUTION:When the time between the pulselike ultrasonic waves 4 is emitted from the transmitter 4 and received with a receiver 9 after reflected from the object 7 at a distance l is expressed by t1 (=2l/ the velocity of ultrasonic wave), the time lag between the timing pulse and the reading signal can be set at t1. In other words, if the transmitter 4 and the receiver 9 are positioned roughly on the same plane while separated 1m from the object 7, the ultrasonic wave from the transmitter 4 can reach the receiver 9 in about 6msec upon reflection. Therefore, if generated after this time interval so that the intermittent amplification circuit F works only for a fixed time, the reading signal permits the sensing of the area within about 1m of the transmitter 4, thereby assuring accurate measurement of the short distance between relatively small objects.

Title: Video distortion signal generating circuit
Inventor: MURAKAMI AKIO
IPC: H04N5/38
Filed: 1985-05-13
Abstract: PURPOSE:To permit continuous adjustment of an amplitude and a polarity of distorted signals with a potentiometer by providing a non-linear circuit outputting only for a period when video signal is either higher or lower than D.C. bias voltage, a differential amplification circuit outputting both in-phase and anti-phase signals and a potentiometer. CONSTITUTION:A video signal of a video input terminal 1 and bias voltage of a bias input terminal 2 are connected with each other after passing through respective diode 11 and resistance 12. If the video signal is outputted only for a period, when video signal voltage from an output terminal 3 of the non-linear circuit 10 is higher than bias voltage and is added to an input terminal 7 of a differential amplification circuits 20, anti-phase signal appears each other at output terminals 4 and 5. If their amplitudes are almost equal, the amplitude of the output signal which appears in a terminal 6 located at a middle part of a potentiometer 30 goes to 0, when the terminal 6 locates in a center of the potentiometer 30. And as its terminal 6 draws near either terminal 8 or 9, the amplitude becomes larger gradually due to the polarity of added signal. Thus a rotation of the potentiometer 30 between its both ends provides simultaneous adjustment of both the amplitude and polarity of the distorted signals.

Filed: 1987-04-23
Abstract: PURPOSE:To decrease the size in a radial direction of a transmission and to shorten the overall length in an axial direction of the transmission, by a method wherein each of shift forks for forward maximum step and reverse step is situated on a single fork shaft. CONSTITUTION:When a shift lever is shifted from neutral to a reverse step, a moving shaft 23 is coupled to the shift lever for movement. Through movement of a shift fork 28 for a reverse step secured to the fork shaft 23, the engaging state of the gear of a transmission is selected to a reverse step. However, in this case, a release mechanism 34 is actuated, the fork shaft 23 and a shift fork 24 for a forward fifth step are released from engagement with each other, and the shift fork 24 is not moved and stopped and held in a neutral position. Therefore, a conventional stationary fork shaft is eliminated, the single moving shaft 23 will suffice for operation of a shift device, and the size in a radial direction of the transmission can be reduced. Further, length in an axial direction can be shortened only by a space by which the shift fork 24 is not moved.

Title: X-ray photographing device
Inventor: SHINOHARA TAKESHI
IPC: G03B42/02
Filed: 1983-06-07
Abstract: PURPOSE:To prevent the loss of a photographic range of a camera to improve its accuracy by keeping a detection level constant when a maximum voltage of the video signal has a certain level or higher in case that the position of an X-ray diaphragm is determined in accordance with the video signal. CONSTITUTION:A system P which detects a peak voltage of the video signal limits the peak voltage to a certain value VC or smaller by a peak level clamping circuit. This clamp level can be set freely by a variable resistance VR1. Then, a threshold level is set to muVp if the peak voltage passing through a buffer 1' and a variable resistance CR is VC or lower, and it is set to muVC if the peak voltage exceeds VC. The aperture width of the X-ray diaphragm in the video signal is detected by a comparator. Since the threshold is set to a cartain voltage in this manner, the aperture diaphragm does not break the photographic range to make it accurate even if a part of a picture is very bright.
