Title: Video camera
Inventor: HANADA NAOKI
IPC: H04N5/232
Filed: 1995-07-22
Abstract: PROBLEM TO BE SOLVED: To provide the video camera advantageous of cost with excellent mass-productivity in which revision of a digital signal processing circuit is not required even when number of horizontal pixels of an image pickup element is increased. SOLUTION: A frequency conversion circuit 50 and a digital signal processing circuit 18 are connected to an output of an ADC 16 in this order. Taking notice of a digital signal processing circuit 18, it is connected after the frequency conversion circuit 50 and operated based on a horizontal pixel numbers from a video recording device 22. Furthermore, taking notice of the frequency conversion circuit 50, the horizontal pixel number of an output signal from an image pickup element 12 is converted. Thus, independently of the horizontal pixel number of the image pickup element 12, the signal equivalent to the horizontal pixel number of the video recording device 22 is fed to the digital signal processing circuit 18 of the next stage.  Thus, even when the horizontal pixel number of the image pickup element 12 is changed, it is not required to retry design and development of the digital signal processing circuit 18.

Title: Friction mechanism for damper disc
Inventor: TAKENAKA MITSUHIKO
IPC: F16D13/64
Filed: 1987-08-21
Abstract: PURPOSE:To absorb a fluctuation in torque by a change in a friction amount, by a method wherein the friction part of a damper disc to change hysteresis torque in two stages is axially resiliently deformed according to the twist of a subplate. CONSTITUTION:A subplate 8 is positioned through a friction washer 25 between the flange of an output shaft and the side plate of an input member to form a damper disc to change hysteresis torque in two stages. A friction part 27 and a slope 37 are formed to the plate 8 and the washer 25, respectively, so that a top part 31 is brought into pressure contact with the washer 25 when the plate 8 is twisted in the direction of an arrow mark R according to transmission of torque. When the transmission torque is increased and the plate 8 is twisted in a given angle arc, the top part 31 is forced into pressure contact with the slope 37, and with the increase in a twist angle, a friction force between the plate 8 and the washer 25 is increased and therefore, a fluctuation amount of the hysteresis torque can be absorbed.

Filed: 1988-08-22
Abstract: PURPOSE:To easily set the gap between a fixed cylinder and an operation ring with specific accuracy by bringing the fixed cylinder into slide-contact with an operation ring on their cylinder surfaces mutually. CONSTITUTION:The fixed cylinder 10 and zoom ring 12 slide on their mutual tapered cylinders. Therefore, when the zoom ring 12 is moved left, its gap quantity increases and when the zoom ring 12 is moved right, on the other hand, the gap quantity decreases. Thus, a washer 29 is put between the rear stage part 10A of the fixed cylinder 10 and the stage part 12A of the front end part of the zoom ring 12 or a washer 31 is put in the stage part 40 of the fixed cylinder side and the stage part 12C of the rear end part of the zoom ring 12 so as to adjust the axial position of the zoom ring 12.

Filed: 1984-10-03
Abstract: PURPOSE:To obtain a wide dynamic range, by using such signals that their refractive index changing cycles are fixed and they control their refractive index changing speeds as impressed signals upon plural electrode pairs on a piezoelectric crystal. CONSTITUTION:A total of (n) pieces of electrode pairs 6 are formed on the plane waveguide of a piezoelectric crystal 1. The pairs 6 are respectively composed of electrode E1-En and a common (COMMON) electrode which is formed so that the COMMON electrode can face to each of the electrodes E1-En at fixed intervals, and the electrodes E1-En are arranged in the described order with fixed intervals between each of them. A sine wave voltage of a cycle D is used as the voltage 7 to be applied across the pairs 6. Since the refractive index changes in accordance with the voltage 7, optical frequency conversion becomes possible and a diffraction grating can be moved while the grating interval of the grating is maintained under a fixed condition produced by the voltage, when the voltage 7 is controlled so that its pattern can be moved onto the plane waveguide 1. Therefore, the frequency of a light can be converted while the outgoing angle of the light is kept constant and a wide dynamic range is obtained.

Filed: 1987-08-24
Abstract: PURPOSE:To precisely overlap plural images by detecting a position display means detecting the home position of a photosensitive body shown by a detector, grasping said home position and beginning to write images in said position. CONSTITUTION:A driving gear 49 driving a photosensitive drum 3 is placed on the rotary supporting axis 47 of the photosensitive drum 3. A rotating plate 53 to which the gear 49 is fitted through a screw 51 is provided with the position display means 55 displaying the home position of the photosensitive drum 3. This home position means a position in which a semiconductor laser from an exposing optical system begins to write on the photosensitive drum 3. The transmitting type detector 57 is placed in a position where the display means 55 can be detected. Since the write start position of the photosensitive drum 3 can be known in such a manner, images can be written in that write start position all the time. As images can be written in the same position, the eccentricity of the photosensitive drum 3 can be overcome; therefore plural images can be overlapped precisely and accurate images can be obtained.

Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To obtain superior frequency temperature characteristics by constituting the crystal vibrator by forming two inter digital electrodes on one surface of a crystal piece and forming a common electrode on the other surface. SOLUTION: On one surface of the AT-cut crystal piece 1, the inter-digital electrodes 2 and 2' are formed to constitute a series resonance circuit and on the other surface, the common electrode 3 is formed. At this time, the frequency deviation Δf of an oscillation frequency from a series resonance resonance frequency (f) is found from Δf/f=1/2r1 (1+CL/C01 )+1/2r<2> (1+Cv/C02 ). Here, r1 and r2 are capacitance ratios viewed from T1 -T2 and T3 -T2 , CL and CV are load capacities, C01 and C02 are the electrode capacitances between the T1 and T2 , and T3 and T2 . Therefore, this interdigital two-electrode crystal vibrator has its oscillation frequency shifted b CV for a temperature compensation crystal oscillator to perform temperature compensation with CL, thereby making the frequency temperature characteristics constant irrelevantly to the frequency shift.

Title: Optical interference-type angular velocity sensor
Inventor: OKADA KENICHI
IPC: G01P15/14
Filed: 1989-08-11
Abstract: PURPOSE:To remarkably reduce scale factor errors by adding an external signal to an output of a phase difference detecting/controlling part and, supplying the same to a sawtooth voltage generating part. CONSTITUTION:Since a frequency of a sawtooth voltage is oscillated by an external signal, there is generated an error component of a fundamental wave component of a frequency of the sawtooth voltage and a higher harmonic wave component of a frequency integral times the fundamental wave component in the phase difference between two lights transmitted by an optical fiber coil 17 and interfering with each other. Even when the error component appears in an output of a photodetector 19, an upper sideband wave component or a lower sideband wave component appearing in the output of the detector 19, or the fundamental wave component or higher harmonic wave component is changed to a predetermined frequency along with the component of a frequency of a biasing voltage to a frequency of a signal mixed with the output of the detector 19 in a phase difference detecting/controlling part 50, and supplied to a synchronizing wave detecting circuit 55 with considerably reduced ratio. Moreover, the frequency of the sawtooth voltage is changed to both an increasing direction and a decreasing direction, whereby the scale factor errors in the positive direction and negative direction offset each other.
