Filed: 1988-05-11
Abstract: PURPOSE:To eliminate a fear that a focus evaluated value is changed by the change of the angle of view and a focus motor is driven unnecessarily by inhibiting automatic focusing action while zooming to a wide angle side is executed. CONSTITUTION:The title device is equipped with an evaluated value detecting means 26 to output the levels of the high frequency components of an image picked up video signal passed through a first HPF9 and a second HPF10 as focus evaluated values for every prescribed period and a focus control means 27 to change the distance between a focus lens and an image pickup element so that either of the focus evaluated values can be the maximum evaluated value, and the device inhibits the automatic focusing action by the focus control means 7 while a zoom mechanism executes zooming action in the direction of a wide angle. Namely, the evaluated value is processed by a microcomputer 26 according to a software way, and the microcomputer 26 sends a command to the focus motor control circuit 27 based on the processed result. Thus, the unnecessary driving of the focus motor generated by the change of the angle of view can be suppressed while the zooming to the wide angle side is executed in which the automatic focusing action is not necessary specially.

Title: Surface treatment of glass fiber fabric
Inventor: TSUJIOKA NORIO
IPC: D06M13/51
Filed: 1980-08-21
Abstract: PURPOSE: To enhance the bonding strength of an org. silane compound to a glass matrix by feeding water to a glass fiber fabric with org. silane applied to wet the fabric and drying the wetted fabric.  
     CONSTITUTION: Org. silane or a soln. of org. silane in an org. solvent is applied to  a glass fiber fabric, and without removing the solvent or after removing the solvent preferably, water is fed to wet the fabric. The wetted fabric is then dried. In this method the org. silane is applied to the fabric in a nonaqueous state, so no silanol is formed. The org. silane is, however, converted into silanol by hydrolysis in the wetting process to form high bonds to the glass matrix. In order to accelerate the hydrolysis of the org. silane, hot water, steam or acidic water adjusted to 3W6 pH is used.

Abstract: PURPOSE: To increase the self-sucking capability of a pump by providing a disc-like valve plate having a conical surface, a cylinder block having a conical surface of slidable contact with the valve plate, and a plunger pressing the cylinder block against the valve plate.  
     CONSTITUTION: The area of the opening part of the discharge-side port 6 of a valve plate 2 along a conical surface A is larger than that of a platelike one, and the port 7 of a cylinder block 1 is formed with some inclination to the direction of the axis thereof so as to connect vertically with the opening part.

Abstract: PURPOSE:To prepare high purity pig iron for casting at a low cost without performing of converter refining, by adding a slag forming agent containing an alkali metal carbonate as a main component to molten pig iron desiliconization-treated to dephosphorization-treat ad desulfurization-treat it. CONSTITUTION:Desiliconization-treated pig iron 10 poured into a tundish 2 from a torpedo car 1 flows through the tundish 2 and is cast into a mold 7 from an outlet at its other end. An outlet for slag 4 is installed in the upstream side of the tundish 2, a skimmer 3 in the downstream side and a feeder 6 in the middle of the both. While the molten pig iron 10 fed to an inflow part for the pig ion flows through the tundish 2, soda ash 11 is fed from a hopper 5 through a feeder 6 to the molten pig iron 10 and formed slag 12 is prevented by the skimmer 3 from flowing into the outlet port of the tundish 2 so that it is discharged from the outlet for slag 4. This prevents the slag 12 from entering the mold 7 and also results in effective performance of dephosphorization and desulfurization teatments of the molten pig iron 10.
