Title: Method for controlling sheet temperature of continuous heat treatment furnace
Inventor: KAMEDA KOJI
IPC: C21D11/00
Filed: 1992-02-28
Abstract: PURPOSE:To restrain the variation in a steel sheet temp. and to stably attain a high yield operation by gradually changing the actual line speed set value given to a controller with a time function at the time of changing the line speed target value. CONSTITUTION:The line speed controller 10 operates a motor 9 so that the value obtd. by a line speed detector 8 is equal to a prescribed value. When the line speed target value changes, the actual line speed set value given to the line speed controller 10 is gradually changed with the time by the time function such as a first-order lag curve by a computing element 15. Further, a fuel gas flow rate set value is calculated as a function of the line speed target value by a computing element 14 and outputted to a fuel gas flow rate controller 11. By this method, a prescribed annealing temp. can be obtd.

CONSTITUTION:Source bias voltage VS is always maintained at constant voltage, and temperature characteristics are given to the bias voltage VQ between a gate and a source by changing gate bias voltage VG in accordance with the variation of temperature. To be more precise, earthed potential and constant negative voltage VEE are divided by resistors 31 and 35, and besides, VC is obtained by inserting three diodes 32, 33 and 34. At this time, as the diodes 32, 33 and 34 have a temperature gradient respectively, the gate bias voltage VG, and the resultant bias voltage VQ between the gate and the source has temperature characteristics. As a result, the bias voltage VQ between the gate and the source, which excellently follows the pinch-off voltage VP of a FET 2, can be obtained. Then, by giving an input signal Vi based on the gate bias voltage VG, the current iP is obtained as the output of the FET 2, and a constant optical output can be obtained as the optical output 16 of an LD 1.

Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent the trunnion of a femur component from disengaging from the lumen of a hip head, by equipping a ceramic hip head with a tapered lumen to form an uneven inside face with peaks and troughs. SOLUTION: Faces 104, 110 of a lumen and a trunnion have uneven or incomplete faces in shapes of peaks 112, 113 and troughs 114, 115 respectively. A layer of a malleable material 106 is covered or coated on a peak 112 on the face of the lumen 102. When a joint receives load, the material 106 flows into a trough 224 so as to disperse the load on peripheries of faces 104, 110 of the ceramic hip head 100 and the trunnion 108. The malleable material 106 eliminates local stress concentration caused by facing peaks 112, 113 on faces of the lumen and the trunnion.

Filed: 1978-06-24
Abstract: PURPOSE:To obtain a simple and stable circuit which generates low-frequency clock pulses through digital operation by making use of a low-frequency alternating- current power supply such as a commercial power supply. CONSTITUTION:Photo coupling elements OCI1 and OCI2 are parallel-connected in mutually-opposite directions and drive terminals are connected commercial power supply CAP. Both outputs A1 and B1 of OCI1 and OCI2 are inputted to logic operation circuits N1 and N2. Applying signals of both waveforms to FF composed of logic operation circuits N3 and N4 as they are prevents rise distortion and fall distortion, caused when waveforms A1 and B1 are obtained by OCI1 and OCI2, from appearing as they are at the output of FF and, therefore, the both are inverted by operation circuits N1 and N2 into waveforms A2 and B2, which are inputted to FF. Consequently, the output waveform of FF becomes X. Namely, terminal A2 is used as the set side of FF and terminal B2 as the reset side, so that FF output waveform X will be inverted only at the time of the fall of waveforms at respective terminals A2 and B2.
