Abstract: PROBLEM TO BE SOLVED: To provide a commodity monitoring element which excels in flexibility and can be applied to the commodities of various forms including the labels, etc. SOLUTION: A label 10 which is attached to a commodity, etc., includes a base material 11 consisting primarily of paper, synthetic resin, etc., and a commodity monitoring element 12 which is attached onto the material 11. The element 12 consists of an Fe-Si alloy wire 20 and a canceling magnetic layer 21 which covers the outer circumference part of the wire 20. The wire 20 is made of an Fe-Si alloy having the Si density of 6 to 7wt.% and has the sudden inversion of polarization when an alternating magnetic field exceeding its coercive force is applied. The layer 21 is made of a high polymer material 25 which is mixed with the electrically hard or semi-hard powder 26. The powder 26 applies a bias magnetic field to the wire 20 to prevent the inversion of magnetization of the wire when it is magnetized.

Its particle size is preferably 0.05 to 10 μm. The thickness of the metal oxide film formed at a time is preferably 5 nm to 10 μm. By forming plural coating film layers having different refractive indices from one another, the obtd. powder shows colors by the interference effect. The metal used for the metal salts is iron, nickel, chromium or the like, and salts are sulfates, nitrates, chlorates or the like.  This method is advantageous in that expensive metal alkoxides are not used as the source material.

Title: Cleaner
Inventor: SEDAI FUMIHIKO
IPC: B29B9/06
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To help a cleaner handle set at a given angle to a holding plate by a simple procedure and allow the cleaner to be put in storage in a narrower space by providing a means to temporarily lock a universal joint around which the handle is rotated. SOLUTION: When a cleaner is used, its handle 1 rotates freely in a position shown by the broken line. When the cleaner is put in storage, on completion of cleaning, the handle 1 is laid down until it comes into contact with a holding plate 3 shown by the solid line almost wholly in parallel to the longitudinal direction of the holding plate 3. When a projection 6 is passed through a two- way section while being elastically deformed and is fit into a cavity 7, the deformation is restored, a fitting state is brought about and the handle 1 is fixed. This allows the cleaner to be stored in a narrower space and to be taken out more easily. When it is used for cleaning, the handle 1 is moved to a position above the holding plate 3, to detach the projection 6 from the cavity 7, allowing itself to rotate around a universal joint.

IPC: C04B7/04
Filed: 1989-11-29
Abstract: PURPOSE:To enable coexistence of cement with gypsum having different melting rates by feeding the total amount or part of dihydrate gypsum fed into a closed circuit to a pulverization chamber on the discharge side of a mill or a place between the discharge port of the mill and an inlet of a separator. CONSTITUTION:A clinker is pulverized. In the process, the total amount or part (>=50% based on the total amount) of dihydrate gypsum to be fed is fed to a pulverization chamber on the discharge side of a mill or a place between the discharge port of the mill and an inlet of a separator. Thereby, the residual dihydrate gypsum and the clinker are fed to the pulverization chamber on the feed side of the mill to perform pulverization in a closed circuit. As a result, hemihydrate gypsum having a high dissolution rate, etc., and dihydrate gypsum having a low dissolution rate can be made to coexist in the resultant cement to produce the objective high-strength cement.

A rectifying plate 5 is provided at the junction inside between the tube 2 and the common tube 3.  By providing the rectifying plate 5, the secondary flow of the cooling medium in a junctioning part of the tube 2 and the common tube 3 is suppressed, loss head is reduced, and the flow of the cooling medium to the right and left of the common tube 3 is made smooth.
