IPC: F23N5/14
Filed: 1979-11-29
Abstract: PURPOSE: To keep combustion always in an optimal state and to control the air- fuel ratio in a stable and reliable manner, by providing a unit for detecting the changing speed of combustion rate which detects the operational speed of a combustion air controlling unit, and controlling the air-fuel ratio in response to the output signal of said detecting unit.  
     CONSTITUTION: There is provided a unit 37 for detecting the changing speed of combustion rate which detects the operational speed of a combusting air controlling unit 34. The unit 37 is connected to a combustion controlling unit 27 to interrupt control of the air-fuel ration when the operational speed of the combusting air controlling unit 34 is higher than a predetermined level. With such an arrangement, it is enabled to keep combustion always in an optimal state by controlling the combustion rate continuously and widely and also to control the air-fuel ratio in a stable and reliable manner even if the flow rate of combusting air is changed rapidly by a quick combustion-rate changing instruction.

Title: Manufacture of rotor
Inventor: KAWAKAMI KOICHI
IPC: G11B5/53
Filed: 1987-06-24
Abstract: PURPOSE:To lessen costy working and assembling by anchoring a rotated member onto the outer surface of a rotating member so as to work both of the radial bearing surface and the outer surface of said rotating member with a chuck reference surface chucked. CONSTITUTION:The chuck reference surface 66 formed on the upper surface of a rotated member 36 is chucked after a rotating member 30 has been anchored onto the rotated member 36. Then, the radial bearing surface 70 and 72 comprising a dynamic pressure type radial fluid bearing, the outer circumferential surface 62 of the rotated member and the lower end surface of the rotated member are processed by both cutting and grinding without removal of a chuck. No problems therefore are in the fit tolerance between the outer circumferential surface of the rotating member 30 and the inner circumferential surface of the rotated member 36. There is, as described above, no need for the accurate working of an anchored section between the rotating and rotated members, costy working and assembling are thereby lessened.

IPC: H02P3/14
Filed: 1978-12-15
Abstract: PURPOSE: To increase regenerative efficiency by properly selecting characteristics of an operational amplifier, suppressing the current flowing into a battery to the value below a certain secified one at the time of regenerative braking, and reducing the circuit loss.  
     CONSTITUTION: When an electric motor is rotating at specified speed, the regenerative braking is conducted by operating an operation dispatcher 7 so as to change a field current command signal V 6  to such size that corresponds to larger field current. If the counter electromotive force of an armature goes up and exceeds the voltage of the battery 1, the armature current flows in a negative direction and the input of a current comparator 35 turns to be positive. The standard current signal V 20  having a certian value as the negative input of the current comparator 35 has been given from a standard current signal generator 34, and a deviation signal V 21  from a turnover signal V 10  and the standard signal V 20  is output from the comparator 35 so as to become the negative input of a subtractor 36. A field current command signal V 6  as the positive input of the subtractor 36 is given, so that the field current is controlled by the output V 22  of the subtractor 36.

Title: Driving and controlling device for motor
Inventor: WATANABE YASUAKI
IPC: H02P6/24
Filed: 1980-11-05
Abstract: PURPOSE:To ensure a stopping position of a rotor positively by turning a motor drive circuit off when the number of revolution of a motor is predetermined value or lower and keeping said off condition even when the number of revolution of the motor reaches the predetermined value or higher until signals for  driving the motor are supplied. CONSTITUTION:When H levels signals are applied to an input terminal 5, a transistor Q4 is at off, motor stopping signals (inverse currents) are extracted from a terminal 3B, and the number of revolution of the motor 1 drops. When the number of revolution reaches prescribed value or lower, the emitters of Q4, Q5 are grounded because a Q1 ia at off and Q2, Q3 are at on, and the application of counter torque to the motor 1 is interrupted. When the rotor is turned in the opposite direction for certain reasons at that time, the voltage of some value is extracted from a revolution number detecting circuit 2, but the Q2, Q3 are at on, and a collector of the Q2 and a base of the Q1 are connected by a diode D. Consequently, the base of the Q1 is substantially brought to grounding potential, the Q1 is not at on, and the positive stoppage of the motor 1 is  ensured.

Filed: 1987-06-23
Abstract: PURPOSE: To quickly lead in the phase with respect to each of many burst input signals by driving a circuit with a control signal synchronized with the burst input signal and a burst selecting signal.  
     CONSTITUTION: A phase detector 3 detects the phase of a burst input signal 1 passing a phase shifter 2, and the output signal of the detector 3 is inputted to a switch 6a. The switch 6a is controlled by the control signal synchronized with the signal 1 and the output signal of an AND gate 9a of a burst designating signal 11a. An automatic phase control loop is closed only for the designated signal 1, and the final value of the phase error voltage of the signal 1 designated at the preceding time is applied to a low-pass filter 4a while the designated signal 1 does not exist. Thus, a stepwise voltage change does not occur in the input signal of the filter 4a and the phase is quickly led in with respect to each of many signals 1.
