Title: Controlling method for motor
Inventor: SATOU HIROSHI
IPC: H02P3/12
Filed: 1982-07-05
Abstract: PURPOSE:To obtain the excellent constant-current controlling performance of a motor by compensating the variation in the gain of a main circuit and the time constant occurred at the resistance stage switching time of a series resistor in the main circuit of the motor by switching the integrated compensation constant of a controller at every resistance stage switching time. CONSTITUTION:The current generated in a motor 1 at the generatively braking time is converted into thermal energy via a resistor 3 and a chopper parallel resistor 4. In this case, the current flow rate of a chopper 5 is controlled by a digital controller 13, the notch of the resistor 3 is switched at the maximum current flow rate time to be partly shortcircuited. Then, the operation to return to the minimum current flow rate is repeated to control under the constant current. The controller 13 operates in the operating period of the chopper 5, a current pattern Ip and a feedback current If are loaded through a bus line DB to the controller 13, which compares and processes them. The resistance stage detection signal of the contact of the resistor 3 synchronized with the resistance stage switching time is loaded through a digital input unit 15 and the bus line DB to the controller 13, and the compensation constants of a control system which are different between high and low speed times are processes and calculated in accordance with a flow-chart shown in the drawing.

Title: Grain discharge device of grain drier
Inventor: MIYAZAKI KEIICHI
IPC: F26B17/14
Filed: 1989-05-08
Abstract: PURPOSE:To shorten the time necessary to finish discharge in the condition that grains are not pushed back to the inside of a grain drier from a discharge device and the grains are smoothly discharged by stopping and controlling an exhauster which sucks the air and exhaust it when the operation of discharging the drying-finished grains reaches near its completion. CONSTITUTION:When the operation discharging drying-finished grains dried by a grain drier 4 outside the drier is carried out and a starting switch is operated, the drying-finished grains in the drier 4 are sent out from a storage room 16 to a drying room 11 where the grains fall down into the lower part by the rotation of sending-out valves 12 and flow down and are supplied into a grain-collecting conduit 10. When the discharge of the drying-finished grains progresses and these are no grains at the upper part of the room 10 to form cavity condition, the amount of exhausted air by an exhauster 2 which sucks and exhausts the air coming from a hot air room 13 through the room 11 and an exhaust room 14 is increased and the current value of a motor of the exhauster, which rotates and drives the exhauster 2, rises up. When the current value rises up over a specified value, the motor of the exhauster is automatically stopped and controlled and the exhauster 2 is also stopped and controlled and the discharge operation of the drying-finished grains is carried out in the condition that the air is not sucked and exhausted.

Title: Coating device
Inventor: OZAKI KAZUTO
IPC: G03F7/16
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform coating film thickness regardless of the temp. change of a coating solution and to save the coating solution and installation space. SOLUTION: A liquid vessel is provided in a nozzle member 19 and a property that the coating film thickness is changed with the temp. change of the coating solution in the liquid vessel is compensated by a property that the coating film thickness is changed with the change of coating speed by the movement of the nozzle member 19 to a substrate 2 by a linear motor 11. Then, the uniform coating film thickness is constantly obtained regardless of the temp. change of the coating solution.  Further since the substrate 2 is vertically mounted without horizontally supporting the substrate 2 like the conventional rotary coating system, the installation space is reduced and the coating solution is applied on the surface to be coated of the substrate 2 while moving the nozzle member 19 along the vertically mounted substrate 2 by the linear motor 11 in comparison with the conventional rotary coating system by applying the coating solution while tearing away to the surroundings.
