IPC: F24F7/08
Filed: 1990-11-27
Abstract: PURPOSE:To reduce the resistance to air suction and feeding at the air suction opening of a sirocco fan and control the occurrence of noises by a method wherein the hub for fixing a fan rotor to a motor shaft is located at the distance equal to a specific fraction of the entire width of the fan rotor from the end thereof on the motor side and two suction openings are provided at both ends of the fan rotor. CONSTITUTION:Since a hub 33 is located in a position A at the distance equal to about 2/3 of the entire width W of a fan rotor 30 from an end part 33a thereof on the side of a motor 31, the overall length of a motor shaft 31a can be made shorter by about 1/3 of the entire width W than that of the counterpart in the conventional device having the hub 33 provided at the right end of the fan rotor 30. For this reason, the vibration of the fan rotor 30 and hence its noise levels can be reduced. Since a sirocco fan 3 is the two-side suction type to suck the air introduced into passages 11 and 12 through two suction openings 32c and 32d into a fan housing 32, the suction resistance can be reduced substantially in comparison with the one-side suction type.

Patent JP-H09145750-A (JP)
Title: Constant-current circuit for digital multimeter
Inventor: TAKEDA SHIGEYUKI
IPC: G01R31/26
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To supply a prescribed constant current to a resistor to be measured even when the power supply voltage supplied to an operational amplifier is low by supplying a constant voltage which is opposite in polarity to the voltage supplied to the high potential-side measurement terminal of the resistor to the low potential-side measurement terminal of the resistor. SOLUTION: A constant-current circuit is provided with an opposite-polarity constant-voltage supplying section 50 which supplies a constant voltage which is opposite in polarity to a compliance voltage VR2 supplied to a constant-current generating section 80 from a compliance voltage generating section 70 to the low potential-side measurement terminal Lo6 of a resistor Rx15 to be measured. Since the section 50 supplies a constant voltage of, for example, +3V to the terminal Lo6 so as to give a 6-V potential difference to the terminal Lo6 as the voltage drop of a constant-current circuit system, the section 70 can generate a -3-V voltage as the compliance voltage VR2.  Since the power supply voltage supplied to an operational amplifier 21 can be as low as -4V to -5V, a stable constant current can be supplied to the resistor Rx15 even when the power supply voltage supplied to an operational amplifier 21 is low (for example, +5V). Therefore, a small-sized inexpensive resistance measuring circuit can be constituted, because no exclusive high-voltage power source exclusively is required for the resistance value measuring range.
