IPC: B28B11/08
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To obtain not only an flat, fine finished surface similar to troweling smoothness, but also give stripes on the finished surface by securing a smoothing roller on the front and stripe forming member on the rear with respect to the advancing direction. SOLUTION: When the carriage 1 is traveled on the concrete article 2 in terms of a side frame, at first, a smoothing roller 4 being situated at the front in the advancing direction rolls on the surface of the concrete article 2, and by allowing the surface concrete to move from the middle to the outside by the use of smoothing means 19 provided on the peripheral surface, its surface is smoothed having no difference of elevation. Next, the trowel plate 5 strokes the surface of the concrete article 2 through vibration for trowel smoothing and finishing the surface into a flat and fine surface while raising moisture in the concrete onto the surface.  Following this, the stripe forming means 6 cut the surface of the concrete article 2 by a large number of stripes 39 for giving stripes on the surface, so that the concrete article 2 is completed in one continuous process in its surface finish and stripe formation by this operation.

Abstract: PURPOSE: To prevent cracks from developing in a casting die using a simple structure, promote the building of a wall, and facilitate the parting of a molding die. CONSTITUTION: A gypsum casting die 30 is arranged in a cylindrical die frame 13 through an upper lid 14, an intermediate lid 39 and a lower lid 17, and gypsum 16 is poured into a space between the casting die 30 and the die frame 13, so that the gypsum 16 becomes solidified. The casting die 30 is positively solidified in the die frame 13 and at the same time, a split face is positively sealed. If sludge (b) is injected into the casting die 30, moisture is absorbed not only by the water absorbing properties of the gypsum 30, 16 but also by buried pipes 32, 35, so that the liquid portion of the sludge is absorbed smoothly to build a wall. After the wall is built to a specified thickness and solidified, foam is ejected as a lubricant to an interface between the casting die 30 and a wall built layer (finished product).  At the same time, a die parting layer is formed to effect a smooth die parting action.

Abstract: PURPOSE:To simplify the structure of a reciprocating valve device used for a fluid exchanging device, for example, a cryopump device for performing expansion cooling and also to decrease drive force for the reciprocating operation of a valve. CONSTITUTION:A first route 5A formed by a passage 2B on the lower part and a passage 2A on the bottom side of a valve chamber 1 is opened and closed by reciprocating an end 3D of a large diameter part of a valve 3. While, a second route 5B formed by a passage 2C on the upper side and an opening part 1A (passage 2D) of the valve chamber 1 is opened and closed by reciprocating a stepped portion 3C of the valve 3. These two passages can be opened and closed by one valve 3 having a simple shape. A small diameter portion 3E is provided in a reciprocating section wherein respective wall side passages 2B, 2C on the way of the valve are in the blocked state. When the passages 2B and 2C are in the blocked state, pressure of fluid in respective passages 2B, 2C is circulated to the side surface opposed to the valve 3 through a clearance 3C formed by the small diameter portion 3E, so as to alleviate the side surface pressure by the fluid. Therefore, drive force required to the reciprocating operation of the valve 1 can be decreased.

Title: Electronic measuring instrument can be remote-controlled
Inventor: MASUDA YOSHINORI
IPC: H04M11/00
Filed: 1991-12-02
Abstract: PURPOSE:To prevent a mode from changing from an on-line mode to an escape mode caused by the malfunction of an MNP modem at the time of transmitting measurement data from an electronic measuring instrument to the side of a public telephone line through the MNP modem interpreting an AT command.
