Title: Ink jet recording device
Inventor: KIDA AKIRA
IPC: B65H29/70
Filed: 1995-02-01
Abstract: PURPOSE: To prevent the occurrence of smear due to rubbing at the time of sheet delivery by selecting the position of a spur gear coming in pressed contact with a sheet delivery roller, in such a way that the section of the gear nearer both ends is positioned more forward in the sheet transfer direction, and the section nearer the center is positioned more backward along the sheet transfer direction. CONSTITUTION: Regarding an ink jet recording device to record data on a recorded material 20A via a recording means 16, the center breadthwise section of the material 20A under delivery to the recorded side of the previously delivered material is kept afloat, so as not to come in contact with that side. A plurality of spur gears 30A to 30C in pressed contact with a delivery roller 25, therefore, are made to have a section nearer both ends positioned more forward in a sheet transfer direction, and the section nearer the center more backward in the direction.  The center section of the recorded material 20A under delivery is, therefore, curled, so as not contact the recorded side of the previously delivered material, and both of the materials can be superposed, due to a dead load for the first time after a recording process, thereby preventing the occurrence of smear resulting from rubbing with the recorded side of the delivered material.

Title: Automatic intermittent switch for ventilation fan
Inventor: MATSUURA SHIYOUJI
IPC: F24F7/007
Filed: 1979-03-27
Abstract: PURPOSE: To rotate the ventilation fan intermittently through the timing adjustment of the automatic switch using permanent magnet and thermolight by means of vacuum heat insulation.  
     CONSTITUTION: When the lever 15 of the switch 2 is connected to contact 3', the heater and motor 11 are energized. When the thermolight reaches tranformation temperature of magnet (about 150°C) with the heating of metal plate 5, the permanent magnet 9 attached to the lever 13 is separated from the vessel 7. Thus, the contact 14 is disconnected to stop heating by the heater 3 and rotation of the motor 11. The thermolight 8 heat-insulated inside the vacuum requires about 55W60 munutes before it returns to the room temperature. By setting the above-mentioned time zone at a given level by the pre-adjustment of the heat capacity of the heater 3, thermolight 8, size of metal plate 5, and spring 18, it is possible to provide a thermolight as intermittent timer for long period of use.
