Title: Powdery product for asphalt composition and asphalt composition
Inventor: TSUJI KEIICHI
IPC: C08L9/06
Filed: 1994-12-06
Abstract: PURPOSE: To obtain a powdery product for an asphalt composition which can be directly added to liquid asphalt and therefore can dispense with a step of forming a masterbatch by adding an antitack agent to a rubber substane of a low Mooney viscosity. CONSTITUTION: This powdery product for an asphalt composition comprising 10-90 pts.wt. rubber substance of a Mooney viscosity (ML1+4 ,100  deg.C) of 30-90 (a styrene/butadiene rubber is desirable because of its easy solubility in asphalt) and 90-10 pts.wt. antitack agent (desirably an inorganic compound, a thermoplastic resin or an organic filler) and having a mean particle diameter of 2mm or below. Because the asphalt composition contains the antitack agent, it can be kept in a powdery state. Because it can be molten even when added directly to liquid asphalt, a step of forming a masterbatch can be dispensed with. By using a suitable antitack agent such as an inorganic compound, the antitack agent can act also as an inorganic filler.

IPC: D05B7/00
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce a needle pricking number by manual aid and to improve operability by providing a first waste knit part formed at the side end part of a fabric main body part and a second waste knit part formed at the terminating end side of the first waste knit part and the fabric main body part over the range of crossing the extension line of a linking line. SOLUTION: A first stitch on the linking lines 22 and 24 of this collar knit fabric 10 is pricked with a point needle at a needle pricking position prior to linking. When an automatic linking device is activated, the collar knit fabric 10 is gradually moved accompanying the rotation of a drum and a feed roller and the needle is successively pricked to the stitches on both linking lines 22 and 24 at a corresponding needle pricking position. For a needle pricked part, a body knit fabric is clamped while moving around the drum and thereafter, it is sewn together at a sewing position by a sewing machine. The sewing machine starts an operation after a waste knit part 18 is passed through the sewing position. At the sewing position, since it is not overlapped with the start end part of the collar knit fabric 10, the waste knit part 18 does not obstruct sewing.

Inventor: WATANABE TAKAHARU
IPC: B22D11/20
Filed: 1989-11-21
Abstract: PURPOSE:To weld inner crack in a cast slab under pressing by heating so that average temp. from surface to center part of the rectangular cast slab becomes the specific temp. or holding the specific temp. and after that, applying the rolling reduction to each parallel face in the rectangular cross section. CONSTITUTION:From the relation figure of ultrasonic wave echo from the inner crack to the draft, it is known that the inner crack can be welded under pressing by applying the pressure of at least >=9% to each parallel face in the rectangular cross section. Further, deformation resistance on the surface part is larger than that of the center part and rolling reduction efficiency on the surface part becomes adverse condition. Then, from the relation figure of temp. gradient to depth in the side of rectangle as the range of excellent rolling reduction efficiency, the range of the optimum rolling reduction welding zone is known. That is, by heating up to or holding the temp. so that the average temp. gradient from the surface to the center part of cast slab before executing the rolling reduction to the cast slab satisfy the inequality, it is known that the rolling reduction efficiency becomes good. Therefore, by applying the prescribed rolling reduction to each two directions of the parallel faces in the rectangular cross section, the inner crack in the cast slab can be press welded with good workability.

IPC: H04N5/376
Filed: 1991-11-19
Abstract: PURPOSE:To reproduce accurate and natural picture without image distortion by selecting out of an interline transfer operation and a line address transfer operation. CONSTITUTION:The line address transfer is performed by releasing the address gate of the selected line by selectively supplying address pulses from shift stages S1 to S8 of a shift register 32 by one line. The interline transfer is enabled by releasing all the address gates by supplying address pulses simultaneously from all the shift stages S1 to S8. At the time of picking up the image while taking a moving subject as a moving picture, the line address transfer is selected. On the other hand, the line address transfer is selected when picking up the image as the still picture of the electronic shutter mode and the interline transfer is selected at the time of the still picture photographing. In any case, the reproduction picture without distortion can be provided.

Abstract: PROBLEM TO BE SOLVED: To form an anticorrosion film on a surface of a structural material and prevent a local corrosion by sealing an aqueous solution as an absorbing liquid containing a halogenated lithium as a main component and a specific weight% of an alkali metal hydroxide and an aluminum nitrate. SOLUTION: An absorbing liquid containing a 0.1 to 1.0 wt.% of a lithium hydroxide and a 0.005 to 1.0 wt.% of an aluminum nitrate is formed with respect to a 65 wt.% of a lithium bromide. A film forming liquid is introduced from a valve 17e when the inside of a high temperature regenerator 1a is empty. The valve 17e is closed and then a valve 17b is opened to operate, and heat the high temperature regenerator 1a causing the film forming liquid to circulate. Steam 14 generated during the above operation is converted to water and formed into a refrigerant 11 by a condenser 2. The refrigerant 11 is supplied into the high temperature regenerator 1a by a refrigerant supply piping 18.  Film forming concentration in the high temperature regenerator 1a is maintained constant so as to form a two layer corrosion-resistant protective film made up of an aluminum compound and an iron oxide on the inside of the high temperature regenerator 1a and that of a piping.
