Title: Casting method for non-chilled casting in die casting
Inventor: TSUCHIDA MASANOBU
IPC: B22D27/04
Filed: 1982-01-08
Abstract: PURPOSE:To improve productivity by charging prescribed molten metal added and mixed with Al and an inoculant into dies which are applied with base coating and working coating in two layers on cavity surfaces and are held at prescribed temp. and removing the casting while specifying casting and removing temps. respectively thereby casting non-chilled castings as cast. CONSTITUTION:Base coating of 0.15-0.5mm. thickness and working coating of 0.02-0.2mm. thickness are applied in two layers on the surfaces in the stepwise cavities of dies shown in the figure. While the dies are heated and held at 100- 350 deg.C, the molten metal which consists of 3.4-4.0% C, 2.0-3.5% Si, 0.1-0.8% Mn, <=0.1% S, 0.1-0.9% P, 0.1-0.8% Cr and is added and melted with a specified amt. of an inoculant at varies amts. to be added within a 0.3-1.5% range is added into the cavity parts. Right after the inoculation, the molten metal is charged into the dies at 1,280-1,400 deg.C charging temp., and after lapse of a specified temp., the casting is removed at 700-1,000 deg.C product removing temp. As a result, there is not need for heat treatment for the purpose of rutile decomposition, therefore, the above-metioned method contributes to energy economization, and further to reduction in the production costs of castings.

Inventor: YOSHIDA HIROSHI
IPC: C23F15/00
Filed: 1988-01-07
Abstract: PURPOSE:To improve the corrosion resistance of a welded zone by removing the coating layer on the connection between two steel pipes coated with a polyolefin-based resin, welding both pipes, coating the welded zone where the steel pipe is exposed with a specified shrinking sleeve, and coating the end with a modified polyolefin sheet by fusion. CONSTITUTION:The coating resin layers 2 and 2a on the connection ends of the two steel pipes 1 and 1a coated with the coating resin layers 2 and 2a consisting of a polyolefin-based resin are peeled to expose the steel pipes 1 and 1a, and both pipes are welded. Since the coating resin layers 2 and 2a are removed from the welded zone and the steel pipes 1 and 1a are exposed at the zone, the shrinking sleeve 3 consisting of the drawn polyethylene with the inside coated with an adhesive is mounted on the weld zone, the sleeve is heated to a temp. higher than the softening point of the adhesive and shrunk, hence the sleeve 3 is tightly attached to the welded zone through an adhesive layer 4, and the welded zone is coated. An acid-modified polyolefin sheet 5, etc., are fused to both ends 3a of the sleeve 3, and the corrosion of the fused parts is obviated.

Title: Measuring method of flow rate of fine particles
Inventor: ICHIMURA SHIGEKATSU
IPC: G01F1/74
Filed: 1985-01-11
Abstract: PURPOSE:To measure the flow rate of fine particles simply without restriction based upon conditions such as inner pressure and high temperature by making the fine particles flow from a fluidized bed formed on the way of a carrier through a dam and measuring the static pressure on the lower part in the fluidized bed. CONSTITUTION:Since fine particles flowing from an inflow port 3 are fluidized by carrier gas blowing up from a dispersion plate 5 to form the fluidized bed 4 and flows out from the dam 7, the inflow volume of the fine particles should be balanced with the outflow volume. The outflow volume is planely fixed in accordance with the height of the upper surface of the fluidized bed 4. The static pressure measured by a static pressure detector 8 fitted to the bottom or side wall of the fluidized bed is planely fixed in accordance with the height of the upper surface of the fluidized bed. Therefore, the outflow volume, i.e. the flow rate of the fine particles, is planely fixed by measuring the static pressure and the flow rate of the fine particles can be calculated from the measuring values of the static pressure by forming a graph or a table of the measured static pressure values. The static pressure can be continuously measured and the flow rate of the fine particles also can be continuously calculated.
