Title: Distance measuring device of camera
Inventor: NIWA YUUKICHI
IPC: G03B13/36
Filed: 1981-03-31
Abstract: PURPOSE: To evade an error in distance measurement due to parallax, an increase in the scale of a two-image relative position detection type distance measuring device, and complexity in adjustment by using one distance measuring optical system in common to a photographic optical system.  
     CONSTITUTION: A photographic lens 1 is used in common as a reference visual- field lens for distance measurement, and a reference visual-field image is formed on a reference visual-field sensor 7. A reference visual-field signal and a comparison visual-field signal obtained from said image and a comparison visual- field image formed on a comparison visual-field sensor 10 through a comparison visual-field lens 8 are made into binary-coded image signal sequences by binary- coding circuits 12 and 13. Both those signal sequences are stored and then while they are shifted relatively and successively, whether the image is in focus or out of focus is detected, bit by bit; and the extent of the shifting performed until a maximum number of focusing is obtained is compared with information on the outward movement position of the photographic lens 1, thus discriminating an in-focus state.

Title: Oscillator
Inventor: SUGAWARA MITSUTOSHI
IPC: H03L7/02
Filed: 1980-04-11
Abstract: PURPOSE:To make a frequency continuously variable by supplying the oscillation output of voltage-controlled oscillator (VCO) to an FM detector and by inputting the output of a comparison between its detection output and a reference voltage to VCO. CONSTITUTION:According to the circuit constant of VCO1 and a voltage applied to a varactor diode, VCO1 oscillates at frequency f1, and its oscillation signal is detected by FM detector 2 to develop voltage V1 at its output according to oscillation frequency f1 of VCO. Assuming the voltage of reference voltage source 3 denoted as V2 to be less than V1, the amplified voltage of difference voltage V1-V2 is developed at the output of comparator 4. This voltage is fed back to the control terminal of VCO1, so the voltage applied to the varactor diode varies. As a result, frequency f1 of VCO1 decreases, and consequently output V1 of FM detector 2 nears V2, so that VCO is stabilized at frequency f2 where both the voltage equal each other.

Filed: 1987-03-03
Abstract: PURPOSE:To store the charge result even when the battery is detached from a device body in case of charging and is completely charged, by providing the battery with a storage means where the power state is stored. CONSTITUTION:When the battery voltage of a secondary battery 1 is reduced to a reference voltage while a copying machine 7 is operated, a microcomputer in the machine body of the copying machine 7 stops the operation of the copying machine and sends data indicating the stop to a memory 2 through a bus 5. This data is reset when a battery unit 6 is connected to a charger 8 and a signal indicating the charge completion is inputted through a signal line 9. However, data is held by the voltage of the secondary battery because the memory 2 is provided in the battery unit 6 even when the battery is discon nected from the copying machine body 7 and the charger 8. Thus, the charge result is stored even in the copying machine where the battery is detached from the machine body and is charged.

Title: Sprinkler
Inventor: TAKAGI TOSHIO
IPC: B05B1/34
Filed: 1987-03-02
Abstract: PURPOSE:To perform water sprinkling with good efficiency by a simple structure reduced in the number of parts, by specifying the shape of a vortex chamber to which a water guide pipe is connected in a piercing state so as to be directed in the same direction as the tangential line of the max. diameter part of the vortex chamber. CONSTITUTION:In the vortex chamber 3 vertically formed on a base part 1, the water introduced from a water guide pipe 5 flows along the inner wall of the vortex chamber 3 to form a vortex stream which in turn further rises toward the upper part while revolving in a spiral form to be raised in its pressure and sprinkled from the nozzle orifice 2 provided to the top part of the vortex chamber 3. That is, since the inner wall of the vortex chamber 3 is formed so as to successively become narrower toward the upper part, the revolving speed of the vortex stream gradually increases and the water pressure thereof is enhanced toward the upper part. Since the vortex stream flies out from the continuous points on the opening edge of the nozzle orifice 2 in a tangential line direction toward a diagonally upward part because of its kinetic energy, water is scattered in a mist of small water droplets simultaneously with the separation from the opening edge.

Abstract: PROBLEM TO BE SOLVED: To secure the junction between metallic films and resin protrusions, by a method wherein the electrically connecting means of electric pads on semiconductor element to metallic films arranged on resin protrusions are provided, while anchor parts encroaching upon a resin package are formed in the parts of the metallic films. SOLUTION: A resin package 12 is formed by mold-forming e.g. an epoxy resin so as to integrally form resin protrusions 17 and an identification protrusion 19 on the specific positions of a packaging surface 16 of the package 12 and then metallic films 13 as outer connecting terminals are formed for covering the resin protrusions 17. Next, wires 18 are arranged between these metallic films 13 and electrode pads 14 for electrically connecting the metallic films 13 to a semiconductor element 11. Next, the specific ranges of the upper ends of the metallic films 13 are encroached upon the inside of the resin package 12 toward the inside of the resin package 12 from the position of the packaging surface 16 so as to form anchor parts 41. Through these procedures, the junction force between the metallic films 13 and the resin package 12 can be increased, thereby avoiding the release of the metallic films 13 from the resin protrusions 17 for increasing the reliability upon the junction force.

Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing the blow-up of slag with respect to a long nozzle for continuous casting.
