Title: Making of photographic print pattern for polymerized photopolymer and product thereof
Inventor: DONARUDO FUOOTO SARIBAN
IPC: G03C5/08
Filed: 1986-09-06
Abstract: PURPOSE: To make it possible to obtain high-resolution photopatterns of a liquid polymer by using non-parallel emitted light by reproducing the photopatterns partially by a phototool making surface contact and partially by a phototool spaced from the surface of a liquid polymer by an air gap. CONSTITUTION: The liquid photopolymer layer 21 having the characteristic to suppress the photoreaction of the liquid photopolymer by the air contact with the surface of the polymer is adhered onto the surface of a base 22. The photopolymer layer 21 is subjected to light exposure on the surface of the base 22 with the non-parallel emitted light 15 which provides polymn. energy through a light transparent picture 16 arranged apart the layer. Then, the non-parallel emitted light 15 is used for production of the high-resolution patterns and polymerizes a part of the liquid photopolymer layer 21 through the layer, allowing the surface layer of the unpolymerized liquid photopolymer 37 to remain. The remaining layer is washed away and the high-resolution patterns corresponding to the opaque video parts 17 of the light transparent picture 16 are produced.

Title: Method and apparatus for starting brushless dc motor
Inventor: O KININ
IPC: H02P6/182
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To cause triggering to move the rotor of a motor from start dead point when the motor is started, by when a first period in which a multiplexer transmits oscillation signals during the low-voltage period of a trigger signal is ended, starting a second period in which the multiplexer transmits operation signals during the high-voltage period. SOLUTION: In order to drive a motor 30 to vibrate the motor both in the clockwise direction and in the counterclockwise direction during a first period, an oscillation signal is first transmitted from a signal generator unit 10 to a driving device 20. When the motor 30 is thereafter moved from its start dead point, the driving device 20 transmits an operation signal to drive the motor 30 so that the motor 30 is rotated only in one direction. (While this is done, the first period ends and a second period starts.) When the motor 30 is moved from the start dead point, the signal generator unit 10 transmits an operation signal during the subsequent second period to drive the motor 30 to rotate the motor 30 only in one direction.

In the case where a hot water opening 15 is closed, the electromagnetic proportional control valve 11 is driven in an opening direc tion, for instance, after it is wholly opened, a burning state of the burner part 6 can be minimized or stopped since an oil-atomized quantity from the nozzle 18 is almost nothing.
