Title: Air conditioner
Inventor: FUJISAKI TADASHI
IPC: F24F11/02
Filed: 1978-06-29
Abstract: PURPOSE: To set a relative humidity desired by a person in a room, by detecting the wet-bulb temperature and dry-bulb temperature to determine the dry-to-wet ratio, which is proportional to only the relative humidity, to control an air conditioner.  
     CONSTITUTION: The dry-bulb temperature and wet-bulb temperature are detected by temperature measuring resistors 7, 8 to set the desired relative humidity in the room by a contact S of a variable resistor 12. If the relative humidity of the room is 40 % when the contact S is positioned at a humidity of 60 %, the potential on a point b' is lower than that on the contact S. As a result, a relay 24 is open, a compressor 28 is not driven and the air conditioner blows air. If the relative humidity of the room is 80 % in said case, the potential on the point b' is higher than that on the contact S. As a result, the relay 24 is closed and the air conditioner continues cooling until the relative humidity of the room becomes equal to that indicated by the contact S of the variable resistor 12.

Filed: 1981-05-26
Abstract: PURPOSE:To improve the yield and operating efficiency of titled painting by flowing air into the boundary part between a flux extruding piston and a flux and retreating the piston at a low speed for a short time then at a high speed in the stage of retreating said piston. CONSTITUTION:When a flux extruding piston 6 arrives at an advance limit and ends flux extrusion, a limit switch 23 detects this and changes over a solenoid- controlled selector valve 21. This connects piping l2 to pressure oil and piping l1 to an oil tank 20, and the piston 6 starts retreating. At this time, the piston 6 is retreated at a low speed by only the motor 16 of a high pressure small capacity pump 18 by the short time (about 1-5 seconds) when the piston head and the residual flux are disconnected. During this low speed retreating, a solenoid valve 14 for air vent is opened to flow air through an air hole 5a into a flux cylinder 5, thereby inhibiting the generation of a vacuum state. Following to this, the piston 6 is retreated at a high speed by the pump 18 and a pump 17 for low pressure.

Abstract: PURPOSE:To generate cassettes recorded in duplicate smoothly without giving hindrance to the transmission of a broadcast source by recording an original source by means of a video tape recorder and dubbing a 2nd cassette when the operating schedule of the recorder has a margin. CONSTITUTION:When a recording request of a broadcast source is given to a cart machine 2, a device controller 11 uses one recorder of a video tape recorder section 4 in response to the entry operation from a system controller 12 to allow cassette in cassettes 1 housed in a cassette housing part 3 to record an original broadcast source. In the case of the dubbing of the recorded original source, the controller 11 makes the dubbing of the cassette 1 with a commercial source recorded thereon being 'already recorded' onto other cassette 1 only when two recorders required for the dubbing are idle. Thus, cassettes recorded in duplicate are smoothly generated without giving any hindrance to the transmission of the broadcast source.
