Title: Copying device
Inventor: HISHIKAWA TAKAHIDE
IPC: G03G15/00
Filed: 1989-09-27
Abstract: PURPOSE:To perform a stable fixing action regardless of the size of a transfer material by providing a means for detecting the length of the transfer material in a conveying direction and controlling the height with respect to the nip part of a transfer material guiding means according to the detected value. CONSTITUTION:The transfer material S is conveyed to guiding plates 22a and 22b to make the lever 20a of a detection means 20 fall. Then, the transfer material S is conveyed to a transfer part T by a pair of resist rollers 21. In the case that a time when the lever 20a falls is longer than a set value, it is decided that the transfer material S is long and a fixing entrance guide 6 is moved to a high position. Meanwhile, the transfer material S is conveyed to the fixing device by the conveying guide 6 after the transfer is performed to the transfer material S in the transfer part T. The leading edge of the transfer material S abuts on a fixing roller 7 at a point Q. By continously conveying the transfer material S, the material S starts to bend with conveying force which is received on its trailing edge. The impact at the time when the transfer material S advances to the nip part N is absorbed with the flexibility. Therefore, the unfixed toner in the midst of transfer is not disturbed and the stable fixing action is performed.

Title: Protective circuit for output of automobile engine control device
Inventor: HASUNUMA TAKASHI
IPC: H02H7/20
Filed: 1992-09-18
Abstract: PURPOSE:To obtain a protective circuit for the output of an automobile engine control device capable of preventing heat generation and protecting a drive stage from overheating by monitoring the output voltage of the drive stage in sampling periods. CONSTITUTION:A control signal A from MPU1 is transferred to an AND circuit 5 and a sampling circuit 9. A permission signal (C) is inputted to an AND circuit 5 from a sampling circuit 9, and the output of the AND circuit 5 is inputted to TR2. When an ON signal is transmitted to TR2, a voltage level E at the junction of TR2 and a load 6 is detected with a level detection circuit 8. The output (F) of the level detection circuit 8 is inputted to the sampling circuit 9 and sampled in fixed periods. A signal from MPU1 and the sampled result are compared with each other to count the number of times of undesirable state, and when the number of times reaches a certain number, it is decided that a short-circuit is brought about, and the permission signal is turned off. Since a conventional current detection resistor is not required, the heat generation can be prevented, and also the monitoring is performed several times, and when the short-circuiting continues, the output thereof is tuned off independently of the control signal, so that a drive stage may be protected from overheating.

Filed: 1985-11-11
Abstract: PURPOSE:To obtain high selectivity for a specific anion by using a metal type org. compd. of which the part enclosed by plural metallic elements form an ionophore as an anion selective material. CONSTITUTION:The titled ion-selective electrode utilizes an ion sensitive film which is formed by dispersing ion sensitive material in a polymer.

Title: Mold for continuous casting
Inventor: ONO ATSUMI
IPC: B22D11/04
Filed: 1985-11-08
Abstract: PURPOSE:To prevent breakout and to improve the quality of an ingot by providing a porous body consisting of a material which does not react with a casting metal in a molten metal flow passage and embedding heating elements around the same. CONSTITUTION:A casting mold 3 is disposed below a crucible 1 having the heating elements 2 and the molten metal flow passage 4 is formed therein. The porous ceramic body 6 which does not react with the molten metal is disposed in the flow passage 4 so as to close the passage 4. The heating elements 5 are attached around the casting mold 3 to maintain the casting metal at the solidifying temp. or above. A dummy bar 7 is positioned under the mold 3 and casting is started. The bar 7 is pulled down and the molten metal is continuously solidified in the outlet of the mold 3. The porous body 6 removes the foreign matter in the molten metal and absorbs the pressure of the molten metal, thereby preventing the excess outflow of the molten metal. The breakout in the outlet of the casting mold is thus prevented and the quality of the ingot is improved.

IPC: F04B15/02
Filed: 1994-09-21
Abstract: PURPOSE: To provide a hydraulic circuit of a swinging valve type concrete pump by which movements of swinging cylinders are stopped when a cleaning pipe is made to leap up so that concrete forcibly feeding cylinders are cleaned. CONSTITUTION: An accumulator 26 and a swing switching valve 27 are provided in order from the upstream side of a pressure oil line 24 in the pressure oil line 24 to swinging cylinders 14, 15. A main switching valve 21 is provided in a pressure oil supply/exhaust line 20 which makes two concrete foreibly feeding cylinders 3 to operate.

Title: Magnetic recording medium and its manufacture
Inventor: SHINOHARA KOUICHI
IPC: G11B5/66
Filed: 1983-12-28
Abstract: PURPOSE:To obtain a magnetic recording medium which is less in dimensional variation and excellent in durability, by interposing a metallic thin-film layer between a high molecular substrate and an applied magnetic layer which uses polymer polymerized by electron beam irradiation as a bonding material. CONSTITUTION:A magnetic recording medium is constituted by providing a metallic thin-film layer 2 between a high molecular substrate 1 and applied magnetic layer 3. When an electron beam 4 is radiated from the applied surface side, the electron beam 4 reaches the interface to the metallic thin-film layer 2 after passing through the applied magnetic layer 3 composed of a bonding material 3a, magnetic powder 3b, and other constituting components not shown in the figure as another electron beam 5 while losing energy. Upon reaching the interface, the electron beam 5 is separated into two parts, one part being an electron beam 7 proceeding to the high molecular substrate 1 after passing through the metallic layer 2 and another part being an electron beam 6 acting on the applied magnetic layer 3 again after it is reflected by the metallic thin-film layer 3. Since the reflected electron beam 6 effectively contributes to the polymerization of the bonding material 3a of the layer 3, the polymerization is sufficiently performed even for areas, to which electron beam does not reach because dispersion of magnetic powder is locally disturbed and the powder is cohered in a constitution, in which the metallic layer 2 is not provided between the substrate 1 and layer 3 and therefore durability is improved.
