Title: Reference voltage generating circuit
Inventor: ISHIJIMA TOMOHARU
IPC: G05F3/08
Filed: 1986-01-31
Abstract: PURPOSE:To attain supply of plural different levels of reference voltage through a single reference voltage generator, by connecting a diode to an output terminal of the reference voltage generator and extracting the reference voltage through the output terminal and the other end side of the diode respectively. CONSTITUTION:The lower limit of the comparison range of a window comparator WC3 is prescribed by the accurate reference voltage delivered from a D/A converter 7. While the upper limit of said comparison range is prescribed by the voltage higher than the reference voltage equivalent to the voltage drop generated at a diode 8 by the output current of an analog power supply. Then the comparison voltage is supplied to the inverted input terminal of an operational amplifier 4 as well as to the non-inverted input terminal of an operational amplifier 5. The amplifier 4 decides whether the comparison voltage is lower than the upper limit of the comparison range or not. While the amplifier 5 decides whether the comparison voltage is higher than the lower limit of the comparison range or not. If it is known from the decision of both amplifiers 4 and 5 that the comparison voltage is kept within the comparison range of the WC3, the output level is set at an H level and otherwise at an L level respectively.

Title: Method of starting rewinding of yarn
Inventor: TERANISHI JUNICHI
IPC: B65H54/28
Filed: 1990-01-31
Abstract: PURPOSE:To promptly reach a steady rotational speed by first giving rotation at a low speed to a traverse cam and engaging a yarn therewith thereafter rapidly increasing the rotation thereof, in the case of starting rewinding of the yarn by simultaneously rotating a friction roller and the traverse cam in stopping. CONSTITUTION:A friction roller 1 and a traverse cam 2 in stopping are rotated first at a low speed only for a predetermined time T1. The rotational speed is slowly increased, and the cam 2 is rotated about 16 turns so that a traverse yarn guide 6 is reciprocated several times for the time T1=4 to 5sec. Simultaneously the roller 1 is accelerated synchronously by holding predetermined rotational speed ratio to the cam 2. About 30 turns of rotation is obtained for the T1 seconds. During this time, a yarn Y, when it touches the reciprocating guide 6 in a side of a low guide piece 12, is introduced into a guide groove 10 along this guide. After the yarn Y is engaged for the elapsed time T1, these rotational speeds are rapidly increased by switching their acceleration ratio in a range of generating no yarn breakage to obtain steady rotational speeds RF, RT.

Title: Air/fuel ratio controller of combustion equipment
Inventor: EGAMI TOYOHIKO
IPC: F23N1/02
Filed: 1990-01-29
Abstract: PURPOSE:To prevent a mismatching in the air-to-fuel ratio control due to the scatter in the mechanical responses of a fan motor and a variation in the responsiveness by controlling the signal for controlling the gas flow rate based on functions of the target air flow rate of a fan and an actual air flow rate. CONSTITUTION:A gas flow rate delaying circuit 22 outputs a signal for the gas flow rate in delay, and it takes in a target air flow rate Ws and an actual air flow rate W and calculates by Pout=P+K(W-Ws) (K being a positive constant). At time t1 the input to a gas flow rate calculation circuit 21 changes from the state in which a target air flow rate Ws1 and an actual air flow rate W1 agree, and when the signal for gas flow rate changes from P1 to P2, the target air flow rate Ws changes from Ws1 to Ws2. At this time since the actual air flow rate W has delay and Ws2>W at the time t1, Pout2<P2 and at time t3 if W=Ws2, Pout2=P2.
