Title: Stabilizer for video camera
Inventor: HORI TOSHIO
IPC: H04N5/222
Filed: 1988-12-28
Abstract: PURPOSE:To suppress the shaking of a camera part and to stabilize a camera by identifying the signal component of a camera moving operation from a signal representing displacement between a camera frame and the camera part, and operating a camera driving means by a camera moving operation signal. CONSTITUTION:When the shaking of a handle occurs under photographing, the shaking thetas occurs in a vertical gimbal 6 by torque generated via the harmful load characteristic L of the gimbal. When the shaking of the vertical gimbal 6 occurs against a coordinate reference axis (a) by an angle thetas, a vertical rate gyro 3 provided at the camera part 5 outputs the angle of the shaking of the vertical gimbal 6, and a control circuit 13 processes and amplifies it, and supplies a current to a vertical torquer 9. The vertical torquer 9 rotates the vertical gimbal 6. Thus, the signal and a physical quantity round a control loop for the stabilization of a video camera. In such a way, control such that the shaking thetas of the camera part 5 can be held at nearly zero is performed, thereby, the posture of the axis (b) of the video camera can sufficiently be stabilized.

Abstract: PURPOSE:To confirm the position of a vein accurately and rapidly by mounting a comparing means comparing the outputs corresponding to the quantities of lights detected by two light detection means and a position display means for displaying whether the quantities of detected lights are different or equal. CONSTITUTION:When a power supply operation switch 5 is closed, the skin is irradiated with light having a wavelength within a red or infrared region in a spot like state from the LED 10 of a light emitting element 2 and said light transmits through the skin to irradiate a vein 38 or other tissue but, since the blood in the vein 38 has specific light absorbing characteristics, the difference between the quantities of reflected lights from the vein 38 and other tissue becomes max. Therefore, when this apparatus is moved to be allowed to coincide with the vein 38 in its position, the quantities of detected lights of phototransistors 11, 12 are equal and weak, and zero or extremely low output voltage is outputted from a differential amplifier 15. Therefore, the voltage applied to LEDs 21, 22 is zero or too low and LEDs 21, 22 do not light. The collector of the transistor 27 of a window comparator 29 becomes an 'H'-level and voltage is applied to the LED 28 arranged at the center as a display means 6 in a forward direction to allow the LED 28 to light. By this method, it can be confirmed that the apparatus is positioned above the vein 38.

Abstract: PURPOSE:To obtain a recorded image without 'blank space' and 'black streak', even if a highly blackish line and a less blackish line appear alternately and restrict noise by using N pieces of pulse for feeding recording paper for subscan to the frequency of divided recordings by a thermal head, allowing a pulse generating device to synchronize the drive of recording blocks with the timing of subscan, estimating the recording cycle of a single line and making a pulse output interval constant. CONSTITUTION:A recording cycle estimating section 21 estimates the cycle of a line to be recorded based on the frequency of divided recordings of a single line and time for block selection for each divided recording. In addition, a subscan feed calculation section 22 calculates data by dividing a cycle which is output from the recording cycle estimating section 21 by the number N of paper feeds for subscan, and determines the interval of pulses. In addition, a comparison circuit 25 compares the content of an ENB output frequency counter 11 with that of a subscan feed counter 24. A subscan feed pulse generating device 23 receives the comparison results and determines the cycle of application pulse and subscan feed pulse to each block. At the same time, the device 23 controls both pulses so that they do not become excessive or short.
