Title: Manufacture of finned pipe
Inventor: SHIMODA NAOKI
IPC: B21D53/08
Filed: 1982-09-08
Abstract: PURPOSE:To give tightening action to a formed body wound around a core pipe by making rotation angle of the core pipe slightly larger than rotation angle of a forming device in intermittent rotation of a forming device consisting of a die rotating body and a pushing die rotating body and the core pipe. CONSTITUTION:A tapelike material 1 is wound around pins 26 raised on a die rotating body 12 and the tip is clamped to a core pipe P. The tapelike material 1 is bent successively by pushing dies 20a, 20b, and the forming device and core pipe P are rotated with pushing dies 20a, 20b in the state of pushing. At this time, rotation angle theta2 of the core pipe P is made slightly larger than rotation angle theta of the forming device and wound so that the formed material 1' wound around the core pipe P itself causes tightening phenomenon to the core pipe P. When pushing dies 20a, 20b are pulled out of pins 26, they are returned to original position by a pulling spring 22. A truck 27 on which the forming device is loaded relatively moves intermittently in axial direction of the core pipe and heated by a heating device and soldered surely. Thus, a finned pipe is manufactured efficiently.

Title: Card insertion type recorder/reproducer
Inventor: NAGAYAMA HARUHIKO
IPC: G11B25/04
Filed: 1978-12-13
Abstract: PURPOSE:To prevent the impairment given to the see-through plate caused by the misoperation by securing the automatic draw-in for the card into the reproducer just through the operation in which the recording card is inserted to some extent into the reproducer in order to secure the reproduction state. CONSTITUTION:When recording card 8 is inserted into case 1, the tip of the card touches card detection part 18a of eject lever 18. With the further pushing, lever 18 has a right turn. In response to this action, damping lever 13 slides to direction A, and at the same time card positioning pins 32 and 33 rise up. When card 8 is pushed more, part 18a has a right turn to give further sliding to lever 13. And then  stud 38 slides to the direction of arrow A, and thus card holder lever 39 turns right.  As a result, card 8 is drawn into the reproducer automatically to stop when the  outer edge of the record touches pins 32 and 33. Then if eject button 7 is pushed  under reproduction, lever 13 moves toward arrow B with projection 13c detached  from the power source to cut off the reproduction circuit. With further pushing of  button 7, card 8 is pushed out up to the card exhausting position via part 18a.

Filed: 1993-06-02
Abstract: PURPOSE:To provide an excellent frequency characteristic and to reduce an interpolation arithmetic operation quantity by using an interpolation function generated by connecting plural quadratic functions in the interpolation circuit to output by converting a sampling interval to provide an output. CONSTITUTION:A control signal generator 45 calculates an address signal of picture memories 41, 43 and an interpolation coefficient of both a vertical interpolation filter 42 and a horizontal interpolation filter 44 based on data representing a zoom position and a zoom magnification outputted from a microcomputer 5 to provide an output. An interpolation relation used for the arithmetic operation of the interpolation coefficient uses functions formed by connecting quadratic functions to satisfy f(0)=1, f(n)=0, SIGMAf(n-a)=1, where n is an integer other than 0 and SIGMA is a sum with respect to the (n). Thus, the deterioration of frequency characteristic is less and the interpolation coefficient is obtained with less arithmetic operation quantity.

Title: Ignition limit detector for internal combustion engine
Inventor: OZAKI MAKOTO
IPC: F02D45/00
Filed: 1980-11-06
Abstract: PURPOSE:To constantly detect an ignition limit on a certain level by finding a partial combustion just before a misfire from a detected result of the maximum pressure in a cylinder of an internal combustion engine. CONSTITUTION:A pressure PiQA in a cylinder at a fixed angle thetaA before the maximum spark advance or on a compression stroke only is found as an initial  condition. The maximum burning pressure Pimax is divided by the PiQA to derive  a result, which is compared with a certain value alpha. Determining whether the  proportional result is greater than the certain value alpha or not is an aid for distinguishing a complete combustion or a partial combustion just before a misfire.  This detects the ignition limit on a certain level so that controls for an air fuel  ratio. EGR and ignition timing can be effectively performed.

Title: Stain proofing of hull plating and the like
Inventor: SHIMATANI SHIROU
IPC: B63B59/04
Filed: 1983-08-29
Abstract: PURPOSE:To prevent the outside plating such as hull and the like from being stained due to the adhesion of aquatic organisms thereonto by a method wherein copper or copper alloy powder is exposed above the surface layer of coating at all times by underwater grinding. CONSTITUTION:Coating material consisting in mixing copper or copper alloy powder with epoxy resin, polyester resin and urethane resin, all of which have poor hydrophile property and at the same time to all of which no rosin or the like is added, is coated onto a hull. The initial stain proofing is performed by the eluation of copper ions from the pigments exposed above the surface layer of coating. At the point of time when the stain proofing effect starts to decrease, underwater grinding is executed so as to expose the copper or copper alloy powder above the surface layer in order to keep on proofing stain. Long term stain proofing effect is obtained by repeating the above-mentioned coating and underwater grinding.
