Title: Heat insulating material filled type soldering vessel
Inventor: KOBAYASHI MITSUMASA
IPC: B23K1/08
Filed: 1980-09-03
Abstract: PURPOSE: To stabilize the temp. of molten solder and prevent solder ejection by filling heat insulating materials into the space between a vessel and an outer case.  
     CONSTITUTION: Heat insulating materials 6 are filled on side faces (4 places) and bottom part (one place) in the space between the stainless steel vessel 2 and outer case 3 of a soldering vessel. This decreases the temp. drop of solder, makes up the low heat conductivity of solder which is the prime cause for solder ejection that occurs during melting of solder, decreases the temp. difference between the solder surface (the part in contact with air) and the bottom part and decreases the solder ejection. Since the temp. drop of the solder is prevented, saving of electric power and the reduction in starting time are made possible.

Title: Firmware transitional programmable sequential logical controller
Inventor: JIYAN FUROORAN
IPC: G05B19/04
Filed: 1985-06-04
Abstract: An apparatus for controlling external devices in a controlled installation following a control sequence includes a scanning pulse generator arranged to generate scanning pulses at regularly offset times, and an input detection circuit comprising transition detectors each of which detectors is adapted to accept a distinct input variable signal associated with an external device or system component and a respective one of said scanning pulses to detect a transition or change of state of the input variable signal. An address signal is produced substantially immediately for accessing a sequential memory in response to the presence of a respective one of said scanning pulses and an input transition. The sequential memory stores data identifying the stages in the control sequence wherein the different storage locations are designated by a respective address defined by the particular input channel and a given stage. The sequential memory is arranged to accept the address signals from the transition detectors at the time an input transition occurs to provide the new stage data in response to each such transition and corresponding address signal. An output function memory stores the command signals for the external devices under control of the apparatus and responds to the new stage data from the sequential memory and level or alarm signals from the controlled installation to provide the associated command signal.

Title: Magnetic levitation type optically driven conveyor
Inventor: OOTAKE SHIYOUJI
IPC: B61B13/08
Filed: 1988-05-20
Abstract: PURPOSE:To improve the service life and reliability as well as to make non- pollution achievable by attaching each magnet to the underside and the flank of a conveying body provided with a sail with such a surface as producing a temperature difference when it is illuminated, and supporting them on a track consisting of a superconductive material subject to magnetic repulsion. CONSTITUTION:A light receiving sail 2 is set up in a conveying body 1 with a glass window made into a vacuum. Then, each magnet 4 is set up on the underside and flank of this conveying body 1 and supported on a track 5 consisting of a superconductive material subject to magnetic repulsion against the magnet 4. In this constitution, if light is applied to a black surface of the sail 2, a thrust is produced from the black side to the while side because of light pressure, so that this conveying body 1 is propelled. At this time since the conveying body 1 is floated repulsion lying between the magnet 4 and the track 5, it is moved in a noncontact state. With this constitution, since it does not include any rotational part besides noncontact, lubricating oil becomes unserviceable so that any drop in its service life is prevented from occurring.

Title: Heat-sensitive stencil paper and production thereof
Inventor: KAMIYAMA KOUICHI
IPC: B41N1/24
Filed: 1984-06-15
Abstract: PURPOSE:To prevent a heat ray transmitting property and an ink-transmitting property from being degraded by an adhesive, by a construction wherein the quantity of an adhesive coating material is gradually decreased in the direction from the adherend surface of a film and a porous tissue paper toward the outside surface of the tissue paper. CONSTITUTION:An adhesive coating material is applied to an adherend surface of the film, while the porous tissue paper supplied from the other side is impregnated with a solvent. Therefore, at the time of adhesion, the coating material applied to the adherend surface of the film penetrates into the tissue paper under the surface tension of the solvent, resulting in that the concentration of the coating material in the tissue paper is highest at the adherend surface and is gradually lowered in the direction toward the outside surface of the tissue paper. The stencil paper thus obtained has a sufficient adhesion between the porous tissue paper and the thin synthetic resin film. In addition, since the quantity of the adhesive coating material used is small and a major portion of the coating material is present at and near the adherend surface, the coating material does not degrade resolution, printability or the like.
