Title: Molding sand of good disintegrating quality
Inventor: HATANO YOSHIYO
IPC: B22C1/02
Filed: 1978-09-08
Abstract: PURPOSE: To improve the disintegrating quality of the molding sand which is used for the self-hardening mold and the CO 2  gas mold, by adding a apecified amount of cane sugar, starch, etc. and oil to the molding sand for which water-glass is used.  
     CONSTITUTION: After cane sugar, grape sugar, and starch of one kind or more, of 0.2W4%, and oil such as vegetable oil, etc. of 0.15W1.2% have been added to silica sand, olivine sand and zircon sand of 100% in weight, as disintegrating agents, they are mixed and kneaded by adding water-glass in addition to the foregoing. As for this molding sand, hydration of the water soluble caking agents such as cane sugar, grape sugar and starch is prevented by adding oil, and the molding sand is interspersed with each pulverulent body. The molding surface which has been molded by this molding sand is stabilized, and since water content is decreased by leaving it as it is, its permeability becomes good and the molding strength is increased. When molten metal is poured into this mold, oil which has been emulsified among sand grains is carbonized after water content is evaporated, and also oil which covers the sand grains makes a carbonized layer between the sand grain and the caking agent, and accordingly, its disintegrating quality becomes good.

Abstract: PROBLEM TO BE SOLVED: To efficiently cool a brake disk, preventing thermal deformation of the brake disc, by interposing a thin plate heat exchanger plate extending by connectiong mounting hardwares each other in the peripheral direction of the brake disk in a state that the brake disk is idly fitted into the mounting hardwares. SOLUTION: A heat exchanger plate 9 is overlapped on the bearing surface 8a of a bracket 8 at first by locating a through hole 9a on the same shaft line as a screw hole 8c to mount a brake disk 7 and the heat exchanger plate 9 on the bracket 8 of a hub 4. At this time, the heat exchanger plate 9 is temporarily held by the bracket 8 by the engagement of the inner peripheral surface of the heat exchanger plate 9 to a projection 8b of the bracket 8. Next, a mounting piece 7b of the disk 7 is overlapped on the bracket 8 and a mounting hardware 10 is inserted into through holes 7c, 9a and the hardware 10 is threadably attached to the bracket 8.  When the disk 7 and the heat exchanger plate 9 are mounted on the hub 4 by the mounting hardware 10 in this way, the disk 7 and the heat exchanger plate 9 become freely movable in the peripheral direction, the radial direction and the shift line direction by a gap D and a dimension L. Therefore, the disk 7 does not deform by thermal expansion due to frictional heat at the time of a braking.

Title: Manufacture of complementary type dielectric isolating substrate
Inventor: SHIBATA SHIGERU
IPC: H01L21/762
Filed: 1984-05-31
Abstract: PURPOSE:To prevent the occurrence of the collapse of a shape in a region adjacent to an N type single crystal island among the corners of a P type single crystal island, by performing epitaxial growing with a mask for the N type single crystal island being extended in the inside, and effectively expanding a single crystal silicon region. CONSTITUTION:An N type single crystal substrate 1 is selectively masked by a silicon oxide film. Anisotropic etching is performed by alkali solution and an N type single crystal island 2 is formed. With a part in the vicinity of the island being made to remain by about 5mum, the N type single crystal island 2 is masked by a silicon oxide film 18. Then P type impurities are doped and epitaxial growing is performed. Thus a P type single crystal silicon layer 7 and a single crystal layer having many crystal defects called a transition region 8 are grown. A polycrystalline silicon layer 9 is deposited on the N type single island other than said layer and region. The polycrystalline silicon layer 9 becomes narrow to the inside of the N type single crystal island 2 by the length the mask 18 is extended to the inside of the N type single crystal island 2. The P type single crystal silicon layer 7 is expanded outward. Therefore, the occurrence of the collapse of the shape due to the etching speed when a P type single crystal island 11 is formed can be prevented in the part adjacent to the N type single crystal island 2 at the next process.

CONSTITUTION:From the coating weights W1, W2 on the front and back surfaces of the steel sheet by using a sheet width direction scanning coating weight measuring instrument 5 for measuring the coating weight in the width direction of the steel sheet 1, a displacing quantity DELTAD=(ln W1-ln W2)/K is calculated with a shape arithmetic device 6 to obtain the steel sheet shape. The shape obtd. from this method is approximated to a quaternal expression and by separating the shape into the symmetrical component and the unsymmetrical component, a linear expression is established between warpage rate of each component and the displacing rate of shifting quantity in the right and left direction of the sync roll 2 or the support rolls 3. Therefore, by using a shape control arithmetic unit 7 for deciding the operating quantity in the right and left sides of each roll and right/left and advancing/retreating driving devices 8, 9, the shape of the hot-dip coated steel sheet is controlled.
