Title: Blower motor controlling device for automobile air conditioner
Inventor: OI SHINICHI
IPC: B60H1/00
Filed: 1989-04-06
Abstract: PURPOSE:To make a blow quantity constant even when a ventilation resistance is changed by detecting the revolution number of a blower motor, determining the difference from a desired revolution number, compensating an output signal of a desired revolution number setting means corresponding to the difference, and driving the blower motor by a compensated signal. CONSTITUTION:A desired revolution number of a blower motor 2 is sent from a desired revolution number setting means 100 to a revolution number compensating means 120. In the meantime, an actual revolution number of the blower motor 2 detected by a revolution detecting means 110 is inputted to a compensating means 120. The compensating means 120 determines the difference between the desired revolution number and the detected revolution number, and compensates the output signal of the desired revolution number setting means 100. A compensated signal is outputted to a drive means 130, and the drive means 130 drives the blower motor 2 based on this input signal. In this constitution, if a ventilation resistance changes to change the revolution number, the desired value is compensated to absorb it, thereby the blow quantity can be kept constant.

Title: Method of controlling air supply fan of centralized air conditioning system
Inventor: YOSHIDA YASUTOSHI
IPC: F24F11/04
Filed: 1986-04-15
Abstract: PURPOSE:To prevent a duct from being damaged by controlling the rotational speed of an air supply fan to a minimum rotational speed when a pressure sensor installed within an air supply duct between an air supply fan and a first fire preventive damper has detected an extraordinary high pressure. CONSTITUTION:In a case where air supply fan 2 is operated under the control based on the damper opening degree of a variable air quantity control unit 4, when a fire preventive damper 8 operates under an erroneous manipulation or an erroneous action and is put into a closed state, a pressure detector 9 detects the extraordinary rise of a pressure within a duct 3 between the fire preventive damper 8 and the air supply fan 2, the pressure sensor 9 transmits a signal for reducing the rotational speed of the air supply fan 2 to a minimum rotational speed before the duct is damaged. This signal controls the rotational speed of the air supply fan 2 prior to a control signal based on the opening degree of the damper of a variable air flow quantity control unit 4.

Title: Logarithmic compression amplifying circuit
Inventor: KIMURA KATSUHARU
IPC: H03G11/08
Filed: 1989-04-05
Abstract: PURPOSE:To obtain a logarithmic compression characteristic stable against temperature change with small deviation by providing plural differential amplifier sections one of transistors(TRs) whose emitter is inserted with resistors different in resistance value with each other and summing collector currents flowing to the TRs. CONSTITUTION:Since the emitter of a TR Q11 has a resistor R1 and the emitter of a TR Q21 has no resistor, an offset is caused at the input stage. Assuming collector currents of the TRs Q11, Q12 respectively as Ic1, Ic1', when the currents Ic1, Ic1' are equal to each other, the voltage between input terminals T1 and T2 is an input offset voltage Voff. A current Io flowing through a load resistor Ro is the sum of collector currents Icj of the TRs Q1j and the logarithmic compression characteristic is approximated by polygonal lines. Since the logarithmic characteristic depends only on the resistor Rj and the constant current source 2j, the variance in the logarithmic compression is reduced.
