Title: Control method of meandering
Inventor: KUWANO HIROAKI
IPC: B21B37/00
Filed: 1984-01-11
Abstract: PURPOSE:To prevent the meandering of a rolling material even when a rolling speed is changed and to stabilize its rolling by changing a gain of differential signal inversely proportionally to a rolling speed. CONSTITUTION:The meandering quantity DELTAX of a rolling material is compared with a center-position set value DELTAr by an operation amplifier 1, to output a meandering deviation-quantity DELTAX' to a differentiation circuit 2 and a coefficient multiplier 6. The deviation quantity DELTAX' is differentiated by the circuit 2 to output its differential signal to a division circuit 3. On the other hand, the signal of a rolling speed V detected by a rolling-speed detector 4 is outputted to the circuit 3, to obtain a ratio between it and a reference rolling speed V0 and simultaneously to multiply it by a differential signal d(DELTAX')/dt. A signal of V0/V. d(DELTAX')/dt is outputted from the circuit 3 to a coefficient multiplier 5, to output a signal of Td.V0/V.d(DELTAX')/dt to an add amplifier 7. Further, the deviation quantity DELTAX' is multiplied by a proportional gain Kp by coefficient multiplier 6, to output the results to the amplifier 7. The amplifier 7 operates a roll-gap adjusting quantity to output it to rolling-reduction control devices 8, 9, which adjust the meandering so as to eliminate it.

Title: Pla circuit
Inventor: TERAMOTO TOSHIYUKI
IPC: G06F1/12
Filed: 1987-01-10
Abstract: PURPOSE:To attain stable operation against a change in the manufacturing condition by forming a circuit pattern of a delay circuit generating a clock for OR item circuit operation by an output pattern of an AND item circuit, and an input pattern of the said OR item circuit of the next stage connected thereto. CONSTITUTION:When the AND item circuit is operated by an input of a clock CK1, the output change in the AND item circuit 1 is propagated to the input of the OR item circuit 2 and the propagation delay time in this case depends largely on the size of the parasitic delay element. On the other hand, the clock CK1 inputted to the delay circuit 3 is retarded by the delay circuit 3 and outputted as the clock CK2 after a time t2. Since the delay circuit 3 includes the delay element formed by the circuit pattern similar to that forming delay elements 4-7, the difference between the times t1 and t2 is almost unchanged. Thus, sure operation is attained even with the varied manufacture condition.

Title: Manufacture of compound roll
Inventor: MAYAMA KAZUNARI
IPC: C22C37/08
Filed: 1989-01-10
Abstract: PURPOSE:To prevent generation of cracks in the axial direction by forming an outer case layer of a wear resistant and highly hard material, forming an inner layer by teeming molten metal of a highly tough material into the outer case layer to weld both the outer and inner layers, and applying isotropic pressure to the outer layer in a gaseous atmosphere having a temp. range in which a surface temp. of the outer layer is not higher than a specific temp. CONSTITUTION:Isotropic pressure is applied to the surface of an outer case layer in a gaseous atmosphere having a temp. range in which a surface temp. of an outer case layer is <=550 deg.C to cool the outer layer. By that composition, tensile stresses acting in the peripheral direction of the outer layer generated by existence of a difference in contraction coefficient caused by structural difference between the outer and inner layers and temp. difference are relaxed by the isotropic pressure applied to the surface of the outer case layer. An outer case layer 1 and inner layer 2 are formed of high alloy cast iron and ductile cast iron, respectively. A mold is resolved at the time when a surface temp. of the layer 1 reaches 500 deg.C and the layers 1, 2 are put in a pressurizing vessel 4. Ar gas is fed by a compressor 8 and the layers 1, 2 are pressurized together with heaters 7 at a prescribed pressure and the pressure is reduced to atmospheric pressure after elapse of a prescribed time and then the layers 1, 2 are extracted.

Title: Right and left wheel driving equipment for vehicle
Inventor: SHIBAHATA KOJI
IPC: F16H48/22
Filed: 1988-01-11
Abstract: PURPOSE:To improve the kinetic performance of a vehicle by providing a torque transmission gear which transmits power to right and left wheels without transiting a differential gear, a torque transmission clutch which makes the amount of transmission torque variable, and a controller which controls the amount of torque transmission according to the kinetic situation of the vehicle. CONSTITUTION:When a load is applied to the hydraulic multiple disk clutch 25 (torque transmission clutch) by a controller during the turning run of a vehicle in the low to middle speed range, for example, the clutch is brought into the engagement state so that the rotation of an intermediate shaft 15 is transmitted to a right wheel output shaft 7 via gears 18 and 14. At this time, since the relation between both the numbers N1 and N2 of the teeth of the acceleration gears 12 and 16 which transmit the rotation from a power transmission shaft 8 to the intermediate shaft 15 and the numbers N3 of the teeth of the deceleration gears 18 and 14 which transmits the rotation from the intermediate shaft 15 to the output shafts 6 and 7 is N4/N3>N1/N2, the revolution speed of the left wheel output shaft 6 turning together with a differential case 2 becomes higher than that of the right wheel output shaft 7. Accordingly, the turning performance in the low to middle speed range may be improved.

Filed: 1987-01-09
Abstract: PURPOSE:To attain the accurate detection of drop-out by detecting the drop-out of a frequency modulation signal in accordance with the output signal of a latch means. CONSTITUTION:If the instantaneous frequency if the frequency modulation signal (a) deviates from a regular frequency range and falls below a minimum frequency, the terminal voltage (c) of the capacitor 103 at a moment when a switch 102 closes falls below a second reference voltage Vr, whereby the output signal (d) of a comparator 105 shows 'H'. A latch 107 latches it, and holds it until the rise edge of the output signal (b) of a next limitter 108 comes. If the instantaneous frequency of the frequency modulation signal (a) falls below the minimum frequency for several periods, the output (e) of the latch 107 continuously shows 'H'. The output (e) of the latch 107 shows 'H' if the frequency modulation signal (a) is deviated to the side of a low frequency, whereby the detection of drop-out can be executed.

Title: Flame detecting device for radioactive waste incineration facility
Inventor: SUZUKI TAKAO
IPC: G21F9/32
Filed: 1988-01-12
Abstract: PURPOSE:To accurately detect flames without any malfunction due to X rays, gammarays, etc., by providing a flame detector at a position where the inside of a furnace can be observed only through a reflecting body provided in the middle. CONSTITUTION:The detector 1 receives ultraviolet rays emitted by flames in the furnace 2 to confirm ignition and extinction. The detection part 1 is provided where the inside of the furnace 2 can be seen only through the reflection body 5, so although the ultraviolet rays can securely be detected, a high-energy electromagnetic wave like X rays and gamma rays travels straight penetrating the reflection body 5, so it never enters the detector 1. Therefore, there is not the possibility that the X rays and gamma rays enter the detector 1 through its light incidence window to cause malfunction. Further, the outer periphery including the front surface of the detector 1 is covered with a shield plate 6 made of a lead material having large radiation cutoff characteristics, so the radiation generated in the furnace 2 is securely prevented from reaches the detector 1 from the circumference and causing malfunction. Consequently, whether or not there are flames is accurately detected.
