Title: Method for controlling and cooling for thick steel sheet
Inventor: YOSHII MAKOTO
IPC: B21B45/02
Filed: 1994-05-31
Abstract: PURPOSE:To prevent uneven cooling in the width direction by estimating a cooling capacity in the width direction by the surface roughness of a rolled stock from roll wear information depending on a roll chance, controlling a water quantity distribution in the width direction according to this estimation, and cooling the rolled stock. CONSTITUTION:Respective flow rate regulating valves 3 are controlled by calculating the water quantities of center, quarter, and edge with a process computer 6, using formula I and formula II according to rolling information from a rolling side, and transmitting this information to a flow rate regulating valve control panel 5. Hereupon, delta(x) : Wear quantity of a roll at point x in the width direction f (D, Hs): Correction factor to be determined by roll diameter D and roll hardness Hs, F(x): Unit width load at point x in the width direction, L: Rolling length, alpha: Thermal conductivity, g(delta): Correction factor to be determined by roll wear quantity, y (thetaw, theta1, W): Water temperature thetaw, surface temperature of a material to be cooled theta1, function of water quantity density W. Consequently, since a water quantity distribution in the width direction, can be controlled, cooling according to surface roughness in the width direction of a rolled stock 8, can be performed.

IPC: G02F1/37
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser having a secondary harmonic component radiation region so that threshold current density or differentiation efficiency of raging of fundamental waves is equal to that of a normal semiconductor laser. SOLUTION: In this semiconductor laser, by using a selective growth technique of an organic metal vapor phase epitaxy method, a thickness of a quantum well activation layer 4 of a secondary harmonic component radiation region 12 is formed to be 10nm, and a thickness of the quantum well activation layer 4 of a gain region 11 is formed to be 20nm, whereby since an effective energy band gap of the quantum well activation layer 4 of the secondary harmonic component radiation region 12 is greater than that of the gain region 11, fundamental waves generated in the gain region 11 are not absorbed in the secondary harmonic component radiation region 12.  Therefore, threshold current density of raging of the fundamental waves is not made greater than a normal semiconductor laser, and a secondary harmonic component generating semiconductor laser that differentiation efficiency of the fundamental waves is not reduced can be obtained.

IPC: F02F5/00
Filed: 1982-07-07
Abstract: PURPOSE:To improve the gas sealability of the piston ring unit for an engine by upwardly inclining the piston ring corresponding to a ring groove, and setting surface roughness from the lower surface of the piston ring and a gap to the ring groove to the prescribed range.

Title: Method and apparatus for detecting passing magnetic object
Inventor: SCHELLER P KARL
IPC: G01B7/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To enable clear detection of a passing magnetic object by making periodic update so that percentage of voltage is maintained within a predetermined tolerance in response to a change which can occur on peak voltage of threshold voltage Vsig . SOLUTION: Threshold voltages VNth and VPth are indicated at an approximate 173 and 2/3 of a path of a resistance voltage divider 34, respectively. Even when peak voltage of Vsig varies or offset voltage contained in Vsig varies, it is understood that the threshold voltages VNth and VPth have been adjusted after each update period so that they are kept at a fixed percentage of peak-to- peak voltage of Vsig . These thresholds vary with time and exhibit a fixed percentage of peak-to-peak differential voltage (updated) at that time always in the signal Vsig . This is remarkably advantageous in that a proximity detector applies binary output voltage further corresponding to a clear approach point and a retreat point of a magnetic object with transition passing when operating in a peak-to-peak percent threshold mode.

Abstract: PURPOSE:To calculate the arrival time of a reflected wave with good accuracy, by comparing a threshold value slightly larger than electric noise and smaller than sound noise by several figures with the amplitude of a reflected ultrasonic wave using the arrival time discrimination part of a signal discrimination means. CONSTITUTION:An ultrasonic pulse generating means II generates an ultrasonic pulse in synchronous relation to the timing pulse from a measuring control pulse generating means I to transmit the same to an article 4 to be measured from an ultrasonic transmitter III.

An arrival time discrimination part compares the amplitude of a signal with a threshold value close to 0 as near as possible, that is, a threshold value E1 slightly larger than electric noise. Then, the time when the amplitude of the signal exceeds the threshold valve E1 is set to the arrival time of the reflected wave to output a discrimination signal.
