Abstract: PURPOSE:To make the capacity of a fluid pressure source smaller to the utmost by constituting a valve operating mechanism so as to regulate the extent of supply pressure in the fluid pressure source so as to cause it to be applied to the requisite operating pressure conformed to a shift mode of the operating mechanism. CONSTITUTION:As for a valve operating mechanism 4, when it is shifted down to 1-3 gear speeds by a change lever 21 as well as when it is shifted up to second gear speed, a high pressure valve 16 is turned to ON, and a low pressure valve 18 to OFF, respectively. With this on-off operation, compressed air in a tank T is fed to each side of valves 7A-7C and 8A-8C at high pressure via the valve 16 and a check valve 17. On the other hand, when it is shifted down to four gear speed as well as when shifted up to 3-5 gear speeds, the high pressure valve 16 is turned to ON and the low pressure valve 18 to OFF, respectively. With this constitution, the compressed air in the tank T is fed to each side of these valves 7A-7C and 8A-8C at low pressure via the valve 18 and a check valve 19. Consequently, work of the compressed air lessens as compared with the case that the high pressure compressed air is uniformly fed to the whole speed range.

Three different air volumes VR, i.e. high, intermediate and low, at the room side are prepared and two different air volumes Vo, i.e. high and low, at the outdoor side are also prepared. Then the formula "outdoor temperature T o =fi(TR.T e ), i=1W6 is obtained. This formula is memorized by the outdoor temperature estimation device 12. Then the detected values T e , TR obtained by the sensors 9, 10 are inputted to said device. Thus the device operates according to the operation condition of blowers 3, 6 to provide a correct estimation of outdoor temperature T o .

Title: Automatic gain control circuit
Inventor: YAMAGUCHI TAKESHI
IPC: H04L27/22
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce level fluctuation and an error by comparing a mean value of an input signal with a reference value, a maximum value and a minimum value so as to classify the input signal into five ranks, and adjusting and correcting a gain signal accordingly so as to reduce a gain control time with a small scale circuit. SOLUTION: I, Q components of a phase detection circuit are given to an input signal level arithmetic circuit 1, in which an input signal level of a demodulation section is calculated. Then an averaging circuit 2 is used to obtain a mean value and to eliminate the instantaneous effect of noise included in the reception signal and the result is given to a comparator circuit 3, where the mean value is compared with a reference value, a maximum value and a minimum value to classify the input signal into five ranks. An integration control circuit 4 executes the processing corresponding to them to an integration circuit 6 and provides an output of an automatic gain signal AGC to a variable amplifier.  The reception level of five ranks 1-5 classified by the comparator circuit 3 corresponds to the reference value, the maximum value and the minimum value, which are used to apply adjustment and correction to a gain signal. Thus, the gain control time is reduced to reduce level fluctunation and error.

Abstract: PURPOSE:To obtain a correct remainder by providing a selecting circuit which sets the output of an arithmetic circuit directly in a dividend register and performing remainder correction processing at the end of division arithmetic processing. CONSTITUTION:An arithmetic flag 4 is set to ''1'' and an arithmetic circuit 3 subtracts the value of a divisor register 2 from the value of a dividend register 1 and then sets a carry flag 5 to ''1'' when an overflow occurs or to ''0'' when not.

The addition, subtraction, and shifting of a dividend and a divisor are carried out repeatedly by word length plus one, and when the flag 4 is set to ''0'' by final arithmetic, a remainder inputted to the register 1 is smaller by the divisor, so the divisor is added to correct the remainder and the output of the circuit 3 is inputted to the register 1 from a selecting circuit 10.
