Inventor: YAMAMOTO SOICHI
IPC: B65G33/36
Filed: 1992-02-28
Abstract: PURPOSE:To obtain a grain conveying/spreading device capable of efficiently conveying without remains, and spreading it over a desired location with a reduction in cost and noise. CONSTITUTION:An upper screw conveyer 100 as a grain conveying/spreading device is mounted on the uppermost part of a grain bin 24 of a grain dryer 10 and consists of a screw 102, a rotary drum 104 and a reduction gear unit 106. The rotary drum 104 has two or more openings. The reduction gear unit 106 is of a hypocycloid mechanism type and connects the screw 102 and the rotary drum 104. Therefore, the rotary drum 104 is rotated at a reduced rotating speed with the rotation of the screw 106. Grain is conveyed by the screw 102 and spread downward by the rotation of the rotary drum 104. As a result, the grain conveying/spreading device is built compact as a whole at a reduced cost without grain left in the rotary drum 104.

Title: Method for burning plastic flake
Inventor: NAKAJIMA MASATO
IPC: B09B3/00
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a novel combustion method using plastic flakes as at least a part of fuel in a high temperature combustion furnace. SOLUTION: As at least a part of fuel, plastic flakes with 5-1,000 μm thickness and 2,500 mm<3> or smaller surface area are supplied to a high temperature combustion furnace such as a cement manufacturing rotary kiln, a calcining furnace, etc., by an air flow at 20 m/s or high flow velocity. Consequently, without causing clogging of a supply inlet due to melting deposition of the plastic flakes, the plastic flakes are stably supplied. As a result, a large quantity of plastic flakes are made usable instead of a main fuel and the treatment amount of plastics is significantly increased as compared with that by a conventional treatment for combustible wastes.

Title: Method for driving liquid crystal display device
Inventor: YOSHIDA HIDESHI
IPC: G02F1/133
Filed: 1987-03-02
Abstract: PURPOSE:To increase the response speed of a liquid crystal by trisecting one scanning period of a liquid crystal display device and applying voltages for changing a display, nonchanging the display and negating a DC voltage component to sequentially selected scanning electrodes in every divided period. CONSTITUTION:One scanning period T is divided to the 1st-3rd divided periods T1-T3. The voltage of such a value as to negate the unbalance component of the applied voltages of positive and negative polarities within one scanning period T is applied to the liquid crystal cell connected to the selected scanning electrodes in the divided period T1. The voltage is 0V if there are no DC voltage components as this time. The voltage for changing the state to a dark or bright state is applied in the 2nd divided period T2. The voltage below the threshold voltage is applied in the 3rd divided period T3 in order to maintain the dark or bright state. Conversely, the voltage of the reverse polarity above the threshold voltage is applied in the case of changing the state to the bright or dark state. Since one scanning period T is trisected and the voltages are changed and applied at each of the divided periods, the response speed of the liquid crystal is increased. Constitution of a large-sized display device by increasing the number of the scanning electrodes is thus possible.
