Title: Starting system for synchronous motor
Inventor: NAKASHIMA KIHEI
IPC: H02P1/50
Filed: 1978-12-06
Abstract: PURPOSE: To prevent an excessive exciting current and properly start a synchronous motor even if the motor produces a counter electromotive force, by causing the magnetic flux of a transformer to approach a stationary level during a preparation period for the starting and then starting the motor.  
     CONSTITUTION: After a synchronous motor 1 is started by a power converter 3, the motor is driven by AC power from a transformer 2. Throughout a preparation period for tge starting, the output signal of a separately-controlled phase rotation circuit 13 is applied to a distribution circuit 16 by a discrimination circuit 14 to perform the separately-controlled operation of a power converter 3 to supply a prescribed phase rotation current. When the rotation phase of the output signal of the separately-controlled phase rotation circuit 13 coincides with that of the output signal of a position detector 7, a phase coincidence detection circuit 15 generates an output signal to excite the field system of the motor 1. At that time, the discrimination circuit 14 applies the output signal of the position detector 7 to the distribution circuit 16 to perform the self-controlled operation of the power converter 3.

Title: Burner of forced draft type
Inventor: TONAI MASANORI
IPC: F23N1/02
Filed: 1986-06-25
Abstract: PURPOSE:To contrive to make the turn-down ratio of a burner larger, by providing a controlling device which controls to operate an air flow rate changing means when a fan reaches its maximum number of revolution, as well as to control the number of revolution of a fan to reach another maximum value. CONSTITUTION:At the time of maximum input, combustion takes place nearly at the yellow limit, with a damper 10 open, and a fan being operated at its maximum number of revolutions. The number of revolution is gradually decreased in accordance with the decrease of input, and at the lower limit, combustion takes place nearly at the limit of a lift. When the input is lowered further, the number of revolution is increased to the upper limit, with the damper 10 closed, and a combustion is started again from the yellow limit. The number of revolution is decreased in accordance with the input, and the combustion rate is lowered down to the limit of a lift. When the input is to be lowered further, a valve 8 to control the number of burner pipes 9 is closed to decrease the number from 7 pipes to 3, and the 3 pipes perform the same operation as that of 7 pipes. In such a manner the variable range of the number of revolution can be effectively used, and the turn-down ratio per burner can be made wide.

Filed: 1988-06-20
Abstract: PURPOSE:To know dislocation between a disk center and a spindle motor shaft and a miss clamp by positioning a reflection type detector, which is composed of a light emitter and a light receiver, in the outer-most circumference of a disk. CONSTITUTION:The reflection type detector to be composed of a light emitter 3 and a photo-detector 4 is arranged on a pick-up 5 and further, the pick-up 5 is moved near the outer-most circumference of a disk 2 by a driving mechanism 6, a position detecting device 7 and a driving device 8.

IPC: G02F1/133
Filed: 1980-10-29
Abstract: PURPOSE:To improve a visual vividness of a reproduced picture, by setting white and black levels properly for conversion of a video signal to a digital signal. CONSTITUTION:A video signal vg is applied commonly to one inputs of (k-1)- number voltage comparators 20, and reference voltages are applied to the other inputs. When the input video signal vg exceeds reference voltages, respective voltage comparators 20 change their outputs, and these outputs are encoded to binaries by an encoding circuit 21 to obtain outputs D0, D1...Di. Reference voltages are obtained by dividing a voltage, which is applied across input terminals 22 and 23, by resistances R1, R2...Rk-2. Thus, a white level is set nearer the black level than the conventional white level, and a black level is set nearer the white level than the conventional black level.
