Title: Continuous cleaning of pulverized coal
Inventor: YAMAMOTO SUEJI
IPC: C10L5/00
Filed: 1980-08-12
Abstract: PURPOSE: To remove inorganic impurity minerals adhered to or weakly combined with coal with consumption of small amounts of power by irradiation of supersonic wave of a specific frequency onto aqueous coal slurry containing a specific proportion of pulverized coal of less than a fixed grain size.  
     CONSTITUTION: An aqueous coal slurry containing 10W60pts.wt. pulverized coal of a mixmum grained size of 10mm or less is flowed down from the inclined face of a supersonic cleaner (b), during which a supersonic wave of 15W50kHz frequencies is irradiated on the aqueous coal slurry. Thus, inorganic impurity minerals, e.g., ash, sulfur, etc, present in the coal can be effectively removed continuously with consumption of small amounts of power.

Title: Back tension generator of tape recorder
Inventor: OSANAI AKIRA
IPC: B65H59/04
Filed: 1979-08-30
Abstract: PURPOSE: To prevent an irregular wow occurring in a tape between a reel and capstan by providing a back tension unit that inhibits the rotation in the forwarding direction of a tape by a ratchet and projection.  
     CONSTITUTION: In play mode, tape 90 is forwarded at a constant speed from the 2nd reel mechanism 14 to the 1st reel mechanism 12. The 2nd reel mechanism 14 never turns rotation part 164 because of the rotating force of the electric motor. Then, ratchet 166 is engaged with the 2nd projection 94 of rotation inhibiting method 96 whose 1st projection 92 is oscillated by the rotation of ratchet 66 to inhibit ratchet 166 from rotating. However, reel engagement part 158, while its rotation relative to rotation part 164 is controlled by frictional force operating between felt 162 of the connecting method and rotation part 164, becomes capable of rotating. The back tension like this can prevent the wow of the tape.

Title: Adapter for controlling electronic flash device
Inventor: INOUE TOORU
IPC: G03B15/05
Filed: 1980-08-11
Abstract: PURPOSE:To permit diversion as an electronic flash device of a film plane photometric type camera by providing a light emitting device which converts the control signal from said camera to a light signal and conducts this light signal to the photodetector of an automatic dimming type electronic flash device. CONSTITUTION:As a device of converting the light emission stop signal from a camera 8, a known electronic flash device is used. The light emission stop signal inputted from the terminals p2, g2 of a connector part 10d conducts a thyristor SCR3. The conduction of the thyristor SCR forces a trigger capacitor C4 to discharge, then a flash discharge tube FT2 is triggered by a trigger coil to emit light. The photodiode PD1 of an automatic dimming type electronic flash device 2 detects the emitted light of the tube FT2 and instantaneously completes the electric charging to a capacitor C3, thereby stopping the light emission of a flash discharge tube FT1. By constituting the adapter in this way, said device is diverted as an electronic flash device for exclusive use with the film plane photometric type camera.
