Title: Control apparatus for steam temperature of boiler and method therefor
Inventor: HOSHI TAKESHI
IPC: F22G5/12
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To automatically obtain a control desired value by supplying the product of a correction quantity correcting coefficient signal for correcting a temperature difference desired value correction quantity signal and a temperature difference desired value correction quantity signal and a temperature difference desired value signal to a superheat reducing device and only adjusting the flow rate of spray water. SOLUTION: A correction quantity function device 51 calculates a temperature difference desired value correction quantity based on the difference in burner coefficient from a subtracter 50 and sends it to a multiplier 52. The multiplier 52 multiplies the temperature difference desired value correction quantity by a temperature difference desired value correction quantity from a correction coefficient function device 48. Thus, the multiplier 52 calculates the temperature difference desired value correction quantity based on the difference in burner coefficient to which a load is added, as the product output, and sends it to an adder 49.  In the adder 49, a temperature difference desired value sent from a temperature difference desired value function device 46 is added to the temperature difference desired value correction quantity based on the difference in burner coefficient to which a load is added, from the multiplier 52. Thus, an actual temperature difference desired value is obtained as a sum output and supplied to a superheat reducing device so that the flow rate of spray water is controlled.

Title: Mechanism for displacing rotary magnetic head
Inventor: TAKEUCHI HIROAKI
IPC: G11B5/588
Filed: 1994-05-09
Abstract: PURPOSE:To form a track having good linearity by fixing the respective one-side ends of leaf springs A to C to the same stationary member, holding a moving member which displaces a magnetic head by the other-side ends of the parallel leaf springs A and B and forming the other end of C on A as a free end. CONSTITUTION:The respective one-side ends of the parallel leaf spring 5 consisting of the annular leaf springs 1 and 2 are fixed to both ends of the stationary member fixed to a rotary drum, etc. The respective other-side ends of this leaf spring clamp the moving member 6 having a permanent magnet. The end 3-1 of the leaf spring 3 is fixed atop the spring 1 above the member 7 and the center line of the member 6 exists in a neutral position (x) in the neutral state shown in Fig. (b). Only the spring 5 acts and the spring 3 does not act when the center line of the member 6 is displaced in the direction A shown in Fig. (b) by the current of a driving coil and a permanent magnet to the position (y). A spring constant is increased by the coupling effect of the springs 3 and 5 when the center line of the member 6 shown in Fig. (c) is displaced in the direction B to the position (y). As a result, the magnetic head is supported with high/low rigidity at the time of signal recording/reproducing. The formation of the track having the good linearity/the dynamic tracking action of the sufficient displacement are thus executed.

Title: Diversity receiver
Inventor: YOKOI ATSUYA
IPC: H04B7/08
Filed: 1986-04-24
Abstract: PURPOSE:To secure the high quality communications and to substantially improve reliability by operating a switching means based on a control signal and transmitting a delay output from a delay circuit by blocking a signal from an A/D converting circuit. CONSTITUTION:If fading occurs in a time t1, a control circuit 5 discriminates a drop in gains in a signal reproduction part, and transmits the control signal to an antenna switching circuit 2 and the switching means 7. Due to the control signal the antenna switching circuit 2 is immediately switched to the side of an antenna 1B, and connects an output terminal from the antenna 1B to the signal reproduction part. On the other hand, when the switching means 7 inputs the control signal, it is switched to the side of the delay circuit 9 after a delay time tau3 elapses, blocks a signal input from the A/D converting circuit 6, and simultaneously transmits delay information from the delay circuit 9 to a D/A converting circuit 8. The switching means 7 maintains such a state for a time taub, then is restored and switched to the side of the A/D converting circuit 6. Thus a drop in gains, which arises at the time of switching the antenna, can be prevented.
