Title: Control for servomotor
Inventor: SAKAMOTO KEIJI
IPC: H02P27/06
Filed: 1985-08-27
Abstract: PURPOSE:To stabilize output torque even on the low torque side when output torque is reduced and output torque is varied extending over a wide range by changing the phase of a command signal for currents made to flow through a winding in response to a torque limiting value and increasing reactive currents. CONSTITUTION:A torque limiting value is converted into a phase shift signal Vr by a D/A converter 31, and multiplied by multiplying D/A converters 24, 25 and correction current commands RTC', TTC' having V phase and W phase are outputted, and a correction phase current command STC' having V phase is outputted. Each phase current command RTC, STC, TTC and respective correction phase current command RTC', TTC', STC' are each inputted to phase shift circuits 27, 28, 29, and outputted as phase current commands corrected RT, ST, TT. Accordingly, since the phase current commands are corrected by the torque limiting value, phase of driving currents advances, and reactive current components increase, thus reducing output torque from a motor M.

Title: Blowing controller for air conditioner
Inventor: TAKANASHI AKISHI
IPC: F24F11/02
Filed: 1987-07-27
Abstract: PURPOSE:To prevent abnormal noises of an outdoor side near exchanger in the early stage of frosting by providing a control means for controlling the number of rotations of an outdoor side blower according to a signal released out of a frost detecting means for detecting the frosting of the outdoor side heat exchanger. CONSTITUTION:When an external air temperature is low during heating operation, moisture in the atmosphere, which has condensed into dew freezes to an outdoor side heat exchanger 3 to obstruct ventilation. When the outdoor side heat exchanger 3 begins to frost, the temperature of the outdoor side heat exchanger 3 begins to gradually fall and is converted into an electric signal by a temperature sensor 13, and said signal is sent to a comparator 14. When the temperature of the outdoor side heat exchanger 3 falls down to a fixed value or below, a signal is outputted from the comparator 14, and a transistor 15 is turned on. This results in a relay 17 being operated through a photocoupler 16, and a power source 18 of an outdoor side blower 5 is connected to a terminal L on a slow speed side, thus stopping the outdoor side blower 5 when defrosting operation is started. Thereby, the air blowing performance of the outdoor side blower and the air volume passing through the outdoor side heat exchanger frosted are well balanced, so that since the turbulence of wind in the vicinity of an outlet port is controlled, abnormal noises offensive to the ear can be prevented.

IPC: H03K3/03
Filed: 1984-09-07
Abstract: PURPOSE:To change easily the frequency to a desired frequency by constituting the titled circuit of an odd number of the 1st inverter arrays connected in series in a ring form and a required number of the 2nd inverter array connected in series and switching a part of the 1st inverter array and the 2nd inverter array. CONSTITUTION:When a level of a terminal 22 is at L, transistors (TRs) 18, 19 are turned ON and TRs 20, 21 are turned OFF, then the circuit is oscillated as a 7-stage ring oscillator comprising inverters 7-13. On the other hand, when the level of the terminal 22 is at 'H', since the TRs 18, 19 are turned OFF and the TRs 20, 21 are turned ON, the circuit acts like a 5-stage ring oscillator comprising inverters 7, 15, 16, 12, 13. Thus, when the oscillated frequency is higher because of variance in elements, the circuit is changed into 7-stage constitution to decrease the oscillated frequency and when the frequency gets lower, the oscillated frequency is decreased by using the 5-stage circuit.
