Title: Servo auto gain control circuit of optical disk device
Inventor: WACHI SHIGEAKI
IPC: G11B7/09
Filed: 1989-01-09
Abstract: PURPOSE:To make a loop transfer gain constant by inserting an oscillation output of the same frequency as that of a servo-band into a servo-loop and making the gain variable in accordance with the reflected light quantity of an optical disk so that a ratio of an input/an output of an inserting means becomes constant. CONSTITUTION:An input signal (e) of an operational amplifier 7 is applied to a BPF 10, an output signal (f) is applied to a BPF 12, and an absolute value of an output is calculated by both wave rectifying circuits 11, 13, respectively. Subsequently, a related frequency of a transfer function G of the BPF is determined to the same as an output frequency of an oscillating circuit 8. Until a difference of an absolute value signal (g) and (h) of a rectifying wave circuit becomes '0', a control circuit 15 switches the potential of a resistance type potential dividing circuit 17 and switches a reference voltage (d). Accordingly, while an oscillation output is inserted into a loop, an ON-period of an analog switch 4 is controlled as the signal (e) = (f), and in this case, an open loop gain is 0dB. Thereafter, a composite driving device 20 moves an objective lens of a head, a focusing error is detected by a detector 1 and an arithmetic circuit 2, and it passes through a variable gain adjusting means and reaches a non-inversion input of an operational amplifier 7, and makes a servo-loop.

Abstract: PURPOSE:To attain appropriate and sure removable of blurs, by providing a means for judging whether the cause factors of blurs are large or small, and by changing the set level of a blur removing mode in accordance with the degrees of cause factors of the blurs. CONSTITUTION:A blur cause factor judging means 51 detects the degree of cause factors of blurring, such as wiper operating condition, the number of passengers, the operating condition of a rear heating wire through switches 51a, through 51d. In this arrangement if the degrees of the cause factors of blurring are large, the output of a humidity sensor 50 is compared with a low level value on a setting unit 52 to set a blur removing mode is set. Further, if the degrees of the cause factors of blurring are small, the output of the humidity sensor 50 is compared with a high level value on the setting unit 52 to set another blur removing mode. With this arrangement an appropriate blur removing control is carried out when it is liable to be blurred, thereby it is possible to prevent a transient dewing phenomenon.

Title: Method for decreasing residual stress in web of wide flange beam
Inventor: AZUMAOKA KOJI
IPC: B21B1/088
Filed: 1986-01-10
Abstract: PURPOSE:To improve the quality of a product and to reduce the cost of production by reheating a wide flange beam in the mid-way or upon completion of rolling with a break down mill then reducing the temp. difference between the web and flanges thereof and rolling the beam with a finishing mill. CONSTITUTION:The wide flange beam is reheated in a heating furnace, etc., in the mid-way or upon completion of rolling with the break down mill to make the reverse of the temp. difference of 70-100 deg.C between the web and the flanges so that the web is made higher in the temp. than the flange in the stage of rolling the wide flange beam with a universal rolling mill group, etc. The wide flange beam is subjected in such temp. state to universal rough rolling and finish rolling. The temp. difference after the finish rolling is offset in accordance with the difference in the thicknesses of the web and flanges by which the temp. difference is made approximately zero. The residual stress of the product after cooling is thus decreased and the product quality is improved by the above-mentioned method. The web waviness of the product is eliminated and the cost for reducing the thin-walled wide flange beam is reduced.

Title: Converter steel making method which reduces phosphorus content
Inventor: KITAURA TOSHIKUNI
IPC: C21C5/32
Filed: 1979-01-12
Abstract: PURPOSE:To perform oxygen blowing of superior dephosphorization reaction by temporarily suspending oxygen blowing at the specific point and blowing inert gas or air by an immersion lance then again continuing the oxygne blowing in the  steel making refining by the oxygen top blowing converter. CONSTITUTION:In producing steel by oxygen-blowing of molten steel in an LD converter, basic slag is formed and oxygen blowing is accomplished through hard blow. When [C] has been decarbonized down to 0.4-1.5%, the oxygen blowing is once suspended. Next, inert gas such as Ar or N2 or oxidative gas such as air is blown for 3-10min at ratios of 0.02-1.0Nm<3>/min/ton. The gas having been blown bubbles in the molten steel to cause stirring action, thereby improving the contact of the molten metal and molten slag and lowering the molten metal temperature. This promotes the dephosphorization reaction. Thereafter, the oxygen blwoing is again continued to decarbonize down to the target [C].
