Title: Automatic focusing device
Inventor: HAMADA MASATAKA
IPC: G02B7/34
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain higher accuracy at the time of selecting one of plural pieces of focusing distance information and to excellently focus on almost all the subjects by evaluating reliability by using both the degree of the contrast of a video signal and correlativity between the video signals from paired line image sensors. SOLUTION: The most reliable focusing distance is selected out of the focusing distances obtained by the line image sensors having a different line direction and focusing is performed based on the selected information. Referring to two kinds of data is a method for deciding reliability. Rectangles arranged crosswise on the image sensor 10 are the images X1 and X2 of the horizontal parts of the cross-shaped aperture of a visual field mask 2 by image reforming lenses and the images Y1 and Y2 of the vertical parts of the mask 2. Then, the line image sensor is arranged in a direction where X1 and X2 are linked and the video signal of the subject image on X2 is superposed on the video signal of the subject image on X1 so as to be deviated little by little by processing operation on the video signal, whereby the correlatively maximum deviation is detected.

Title: Photoreceptor cleaning device
Inventor: YANAGAWA NOBUYUKI
IPC: G03G21/00
Filed: 1980-07-15
Abstract: PURPOSE:To effectively recover the toner by providing a static nonmagnetic sleeve disposed on photoreceptor surface, a rotatable magnet element having plural magnetic poles contained therein, a means for removing the magnetic toner attracted on the nonmagnetic sleeve surface and a toner recovery means. CONSTITUTION:The N pole of a magnet 47 is directed outward and its S pole is contacted with a yoke 46 comprising a ferromagnetic material. This causes the S pole to be produced at the tip of the fin 46a of the yoke, thereby forming the magnetic field between the same and the N pole of the magnet 47 adjacent thereto. A toner recovery case 45 has a nonmagnetic guide 45a conforming to the contour near the sleeve 42 and a nonmagnetic scraperplate 49 is fixed to the top end thereof. The free end of said plate abuts on the peripheral surface of the sleeve 42. When the transfer of visible images is finished and the photoreceptor 13 having left the developer on the surface turns and comes to the cleaning portion, it is attracted to the magnetic field on the magnet element 43 and is transferred from the surface of a belt 13 to the surface of the sleeve 42. The developer thus scraped from the sleeve 42 surface is successively fed into the deeper part of the recovery case 45 until the developer is filled up to the full capacity of the case.

Abstract: PURPOSE:To enable the execution of checking at high speed and the easy detection of a minute pattern, by a method wherein a slit-shaped light beam is made to enter an objective lens for illumination having a large numerical aperture so as to form a fine linear light beam on an object of checking. CONSTITUTION:A laser light from a laser 21 is formed into a parallel flux of light by lenses 22 and 23. After passing through a filter 24, it is reflected by a mirror 25, passes through a prism 26 and enters a cylindrical lens system 27.

A fine linear beam is formed on an object of checking. This linear beam is detected by an objective lens 30 for detection and imaged on CCD 34 by an imaging lens 33 through the intermediary of an adjusting mirror 31 and a mirror 32. A minute pattern is detected by moving a stage 35.

IPC: G01S7/285
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a microwave detector which can detect microwaves arriving front the front side and back side together with the receiving directions. SOLUTION: Mixer diodes 8a and 8b respectively mix the frequencies of the outputs of antennas for front side and back side oriented in the opposite directions with the frequencies of the outputs of first local oscillation circuits 7a and 7b for front side and back side having different oscillation frequencies and a second mixer 10c mixes the frequencies of the diodes 8a and 8b with the frequency of a second local oscillator 10b which makes sweeping operations in the mixer 10c.  Since the detecting areas of the output signals from the antennas for front side and back side can be separated from each other within the sweeping range of the second local oscillation circuit 10b, a function which discriminates the arriving direction of microwaves detected based on the sweeping position information of the second local oscillation circuit 10b when the microwaves are detected is provided to a microwave detector.

Title: Frequency dividing device
Inventor: KANEKO MAKOTO
IPC: G10H5/06
Filed: 1981-06-23
Abstract: PURPOSE: To increase frequency dividing ratios by forming period data in which the rate making signals generate in each bit corresponds to the weighting on the basis of counted outputs, comparing the frequency dividing ratio data with the period data and, when a real bit exists in both the data, inhibiting the counting operation.  
     CONSTITUTION: A 4-bit synchronous binary counter 10 counts up clock pulses and generates outputs Q 1 ∼Q 4 . Based upon the counted data Q 1 ∼Q 4 , a period data forming circuit 20 forms period data in which only one bit out of outputs CD 1 ∼CD 4  is "1" and the rate that each bit becomes "1" corresponds to the weighting of each bit, 1:2:4:8. An inhibiting circuit 30 compares the period data CD 1 ∼CD 4  with frequency dividing data DD 1 ∼DD 4  in every bit and, only when there exists a bit making both the data "1", inhibits the supply of clock pulses to the counter 10. The frequency dividing ratios can be changed in the range of 1/16∼1/31.

Filed: 1982-06-07
Abstract: PURPOSE:To prevent a welding cable from deteriorating in high frequency insulation, by providing a high frequency insulating layer to an arc welding equipment which uses a nonconsumable electrode at the contacting part between the welding cable and a holding frame. CONSTITUTION:The welding cable 14b is sheathed with an insulating tube as the high frequency insulating layer 26 at the contacting part where the cable 14b contacts the metallic holding frame 22 of a welding wire feeding device 20 so as to evade the direct contacting between the insulating layer of the cable 14b and holding frame 22. Consequently, the insulation deterioration of the cable 14b due to a high frequency current at the start of welding is prevented and arc generation between the cable 14b and frame 22 is eliminated securely. Therefore, effective welding operation by a stable arc is carried out between the nonconsumable electrode 12 and a base metal 18. The insulating tube may be provided on the side of the holding frame 22 as a substitute for the cable 14b.

Title: Radio get-in/out-of-room control system
Inventor: NAKAGAWA SATORU
IPC: H04B7/26
Filed: 1989-04-19
Abstract: PURPOSE:To discriminate the ID signals by using a transmitter to transmit the ID signals in each fixed cycle and transmitting continuously the ID signals with change of their output cycles in order to avoid the overlap of ID signals. CONSTITUTION:A center 1 contains a computer at the fixed side and is connected to plural local radio control devices LRC 4 via a central radio control device CRC 2 and a transmission line 3. Then these LRC 4 are related to the transmitters 6 via the receivers 5. The receivers 5 are attached at the places where the traveling objects get-in and out of the rooms and the transmitters 6 are attached to the traveling objects respectively. Each transmitter 6 uses a faint current to transmit the ID signals in each fixed cycle. At the same time, the output cycles of the ID signals of the transmitter 6 are changed and transmitted continuously. Thus these transmitters 6 never overlap each other at a certain time point since the output frequencies of the ID signals to be transmitted are different for each of transmitters #1 - #n. As a result, the ID signals can be discriminated successively at above time point with high accuracy.
