Title: Heat soldering iron using liquefied gas
Inventor: NAKAJIMA MASAHIKO
IPC: F23D14/28
Filed: 1984-05-14
Abstract: PURPOSE:To enable complete combustion of fuel-air mixture through sufficient contact of combustion catalyst with the fuel-air mixture and to enable confirmation of the temperature of the forward end of a soldering iron from the outside, by a method wherein combustion exhaust gas is exhausted through the forward end side of a combustion chamber, and a combustion confirming hole is formed in the outer surface of the combustion chamber. CONSTITUTION:Although gas flows through a square through-hole 6a and a U-shaped groove 6b of a combustion catalyst 6 and is exhausted through a combustion exhaust port 7, non-flame complete combustion takes place during passage of the gas through the combustion catalyst 6. In which case, since a gas flow passage, rectilinearly extending from the base and toward the combustion exhaust port 7 at the forward end of a combustion chamber, is formed within a combustion chamber 2, fuel-air mixture is prevented from gathering in the combustion chamber 2, and the inside of the combustion chamber 2 is always maintained at a low pressure, and a nozzle plate 18 part is prevented from being decreased in an ejector action. This enables ensurance of a sufficient amount of the air in the fuel-air mixture, and enables non-flame complete combustion of the fuel-air mixture. Further, since the forward end of the combustion catalyst 6 can be visually watched through the combustion exhaust port 7 from the outside, a combustion state can be confirmed.

Title: Aluminum alloy tube having smooth uneven pattern
Inventor: YAMAMOTO TOSHIHARU
IPC: B21D31/00
Filed: 1987-04-21
Abstract: PURPOSE:To prevent the generation of a defective image as the supporting body of a photosensitive drum by making it the aluminum alloy tube of specified outer diameter and thickness with the slope part continuing to the outer most part of the outer surface having in the axial direction the uneven pattern continued by a projecting R at the external part. CONSTITUTION:The blank tube 4 of aluminum alloy is fitted to a mandrel 5, fed in the axial direction by abutting to the three rollers 7 having an R worked in a mirror face and the aluminum alloy tube 1 forming an unevenness on the outer surface is formed. An insulating body 2 is laminated on the aluminum alloy tube 1 in 10mm-200mm outer diameter and 0.5mm-3mm thickness having a smooth uneven pattern on the outer surface and a photosensitive body 3 is laminated further thereon to make a photosensitive drum. These laminations are adjusted by a dipping method and the thickness by the control of the lifting speed. The generation of the defective image of an interference fringe, black point, etc., in printing as the supporting body of the photosensitive body drum for an optical printer can thus be prevented.

Title: Automatic focus detecting device for camera
Inventor: FUKUHARA TOORU
IPC: G03B13/36
Filed: 1981-06-22
Abstract: PURPOSE: To detect the focus accurately independently of the variance of the F value upon film exposure, by correcting a focus detection signal by a correcting signal corresponding to the variance of the F value.  
     CONSTITUTION: A focus detecting element 11 receives the output of a photoelectric transducer array 4 to detect the phase difference between lights of two divided regions of the exit pupil which are symmetrical about the optical axis of a photographic lens. A deviation from the focus is calculated in a converting circuit 12 from this output and is inputted to an AD converter 13. The lens discriminating signal from a lens discrminating circuit 14 and the F value signal from a signal circuit 15 are given to a decoder 16, and an address signal is inputted to a storage circuit 17 to output a focus correction quantity signal. A correcting circuit 18 receives outputs of the AD converter 13 and the storage circuit 17 and adds both outputs and supplies the result to a display circuit 21, a comparing circuit 20, and a motor controlling circuit 23 to control the focus through a motor 24. Consequently, the focus is detected accurately independently of the F value for film exposure.

Filed: 1979-07-28
Abstract: PURPOSE: To pick up at high speed the profile of flat diagram drawn on the diagram only with one dimensional operation, by processing the edge graph unidimensionally and picking up the profile lines.  
     CONSTITUTION: The data of n-1-row, n-row and n+1-row are given to the buffers 1W3. Data are picked up sequentially from n-th row and the 1st column to check whether or not the n-th row m-th column is the edge point. If it is the edge point, the rejection point or starting point is discriminated by the window 4 of 3×3. In case of rejection point, m+1-th row is advanced to rewrite the domain table 10. The rewrite of table 10 is made that the presence of edge point of the priority order determining logic diagram is checked and if the edge points are a plurality, one point is determined by using the priority order determining theory. To the edge point decided, the coordinates are calculated from the present point. The present point is checked for which any point in the domain table 10 is in agreement and the next point is decided with the priority decision theory.

Title: Magnetic recorded data processing system
Inventor: MIYASHITA NAOKI
IPC: G11B20/10
Filed: 1991-04-26
Abstract: PURPOSE:To suitably process magnetic recorded data by measuring magnetic inverting time while carrying a magnetic card, comparing this measured time with the magnetic inverting time of NULL data and correcting it while considering the fluctuation of carrying speed. CONSTITUTION:Paper sheets are supplied from a roll paper medium 20, cut into the rolled paper of a suitable length by a cutter 11 after passing through a carrying path 10, magnetically recorded by a magnetic write head 12 and printed by a black ribbon 16 and a red ribbon 17, and the card is issued from a port 02. When canceling, the card is inserted from a card slot 01 and stopped at a save position 22 after reading the magnetic information by a read head 13. The data on the card positions the NULL data at the head and end parts and there is a data main body at the middle point. When the carrying speed is fixed, for reading, the magnetic inverting time of the data main body is measured with the NULL data as a reference and since there is the fluctuation of the carrying speed, the data are processed while correcting it.

Title: Conveyor apparatus for glass tubes
Inventor: TOYAMA FUMIAKI
IPC: B65G49/06
Filed: 1984-05-14
Abstract: PURPOSE:To prevent the interference-breakage of a glass tube and allow the conveyor speed to coincide with the speed of the next process by loading each glass tube onto the supporting hooks arranged at equal intervals on the feeding- side conveyor which travels continually and transferring the glass tube onto the receiving-side conveyor through a plurality of inclined chutes on one side midway on a vertical traveling passage. CONSTITUTION:Each glass tube (a) is supported onto the glass-tube supporting hooks 1 installed in equal pitch onto the feeding-side conveyor A onto stripes of endless chains 2. The inclined chutes C1 and C2 are arranged in two stages in close to the top edge of the hook 1 in the leading-out part E of the conveyor A. Solenoid valves midway in air feeding pipes 4 and 4 are opened and closed intermittently corresponding to the pipe (a) feeding speed and the feeding pitch of the conveyor A, and the pipes (a) which reach the positions of the inclined chutes C1 and C2 are discharged by the injection force of the high-pressure air supplied from nozzles D1 and D2, and sent onto the receiving-side conveyors B1 and B2 at the lower edges of the chutes C1 and C2. Therefore, the pipe (a) can be prevented from interference-broken, and the conveyor speed can be allowed to coincide with the processing speed in the next process.
