Title: Structure of furnace wall
Inventor: YAMAGUCHI KIMIO
IPC: F27D1/04
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To enable a superior thermal insulation and a superior temperature keeping state to be attained and further enable a superior strength and a superior durability to be kept without increasing a thickness of a furnace wall. SOLUTION: A second furnace wall member 2 formed into a flat plate by refractory material opposing against extremity ends 4b of protrusions 4 is laminated on a first furnace wall 1 having a plurality of column-like protrusions 4 integrally formed at one plate surface of a base section 3 formed into a flat plate by refractory material so as to form a space 5 with some protrusions 4 being placed between the first furnace wall 1 and the second furnace wall 2. With such an arrangement as above, a heat conduction is reduced by the space 5 and an expansion or shrinkage is adapted by a strain of the protrusions 4 even if the expansion or shrinkage caused by a variation in temperature is produced at the plate portion.  Accordingly, even if the furnace wall is thin, it may have a superior heat insulating characteristic and a temperature keeping characteristic and also it may keep a superior strength and a superior durability.

Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To judge the presence or absence of the connection of an analog telephone terminal by recognizing whether a connection means is connected with a terminal equipment or not by using a connection confirmation signal. SOLUTION: When an analog telephone terminal 22 is in a stationary state, a SW 18 is switched and the connection confirmation signal generated from an AC signal generation part 17 is transmitted to an analog telephone terminal 22. At this time, an AC loop is formed in the analog telephone terminal 22 if the terminal is in an on-hook state. Therefore, the transmitted connection confirmation signal is received again by a connection connector part 11 in a digital data transmitter 1. The effect is detected in an AC current measuring part 20. Namely, when the connection connector part 11 is connected with the analog telephone terminal 22, the connection confirmation signal transmitted to this analog telephone terminal 22 is detected by the AC current measuring part 20.  Therefore, the physical connection of the analog telephone terminal 22 can be confirmed by the detection in this digital data transmitter 1.

Abstract: PURPOSE:To enhance resolving power in detection while enhancing the intensity of diffracted light to be detected by projecting monochromatic light of double wavelength having slightly different frequencies to first and second objects from two directions symmetric to the optical axis. CONSTITUTION:Monochromatic light of double wavelength having slightly different frequencies is projected to diffraction gratings 36a, 36b of first and second objects from two directions symmetrical to the optical axis at an angle of thetai/2, where thetai is the angle between the optical axis and + or - 1st order direction of diffracted light being taken out upon impingement in the direction of the optical axis. A -1st order diffracted light, i.e., a light diffracted reversely to the direction of impingement, and a zero order diffracted light being diffracted in same direction are taken out from both objects M, W and subjected to interference with each other thus producing first beat signals on the opposite sides of the optical axis from the objects M, W. On the other hand, -1st order diffracted lights taken out on the opposite sides of the optical axis are subjected to interference with each other to produce a second beat signal. Displacement amounts of the objects M, W are then determined by measuring phase differences based on the first and second beat signals.

IPC: B29L7/00
Filed: 1989-12-08
Abstract: PURPOSE:To stabilize the frost line of bubble and consequently enhance the quality of the film concerned by a method wherein the domain ranging from an air ring for cooling the neck part of bubble and its upper part above the frost line is surrounded with an inverted conical net and the surroundings of the net are cooled to a certain temperature. CONSTITUTION:Bubble 7 is formed by extruding molten thermoplastic elastomer composition through the annular orifice 11 of a die. At this time, the diameter of the bubble 7 just after extrusion is small due to low melt tension, resulting in forming the so-called neck part 71. In the neck part 71, the bubble 7 is stretched mainly in longitudinal direction (MD). Next, the bubble 7 expands itself abruptly so as to have the predetermined bubble diameter. In the expansion part 72, the bubble 7 is stretched not only in MD but also in lateral direction (TD). Near the almost upper end of the expansion part 72, a frost line is present and the thermoplastic elastomer composition turns into cooled and solidified state here. The bubble is further cooled with a second cooling ring 3 and a third cooling ring 4, both of which are provided in a bubble region 73, which lies above the frost line 74.
