Title: Paper pipe or sheet-like nonwoven fabric adsorbed calcium alginate and its production
Inventor: YAMAZAKI TATSUO
IPC: D06M101/16
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain a nonwoven fabric adsorbed calcium alginate particles, having not only a moisture-absorbing effect but also an easily moisture-releasing effect under a low humidity atmosphere, having no toxicity to human bodies, excellent in safety, easy in handleability, and having an excellent gas-permeating effect. SOLUTION: Alginic acid having carboxyl groups in the molecule and gelated with polyvalent metal ions to form a chelate structure is mixed with sodium hydroxide, etc., to produce sodium alginate. An aqueous solution containing the produced sodium alginate in a concentration of 2-3% is mixed with calcium sulfate or calcium chloride containing calcium ions to form the gel of the ion- exchanged calcium alginate. Powdery sodium alginate and powdery calcium sulfate or calcium chloride are also mixed with each other and subjected to their solid-solid reaction by the use of a ball mill, etc., to form powdery calcium alginate. A paper pipe or sheet-like nonwoven fabric main body is allowed to adsorb the calcium alginate particles to form the paper pipe or sheet-like nonwoven fabric adsorbed the calcium alginate particles.

Title: Hot air heater
Inventor: YAMAMOTO TERUO
IPC: F24H9/20
Filed: 1977-11-07
Abstract: PURPOSE: To provide a hot air heater wherein a senser for sensing the temperature of suction air is provided, and when the temperature of suction air is lower than a predetermined value, the quantity of blast air is reduced to make the induced air temperature almost the same as that at ordinary time, this pleasant heating being obtained.  
     CONSTITUTION: In a case where the temperature of suction air at the time of starting heating is lower than the sensing temperature set by a senser 6, the senser 6 which has sensed it operates to energize the air quantity adjuster to reduce the rotational number of a blower 5. For this reason, the quantity of blast air passing through a heat exchanger 4 is reduced to attempt to raise the temperature of induced air. Accordingly, unpleasantness due to cool air induction is not imparted and pleasant heating can be carried out.

Title: Thread rolling tool
Inventor: SATOU YUUJI
IPC: B21H3/02
Filed: 1979-10-15
Abstract: PURPOSE: To improve productivity and prolong life even of a rolling tool of a small size for which dimensional accuracy is requested, by dulling and rounding the angle parts at the end of the thread parts of the thread rolling tool.  
     CONSTITUTION: Angle parts 2a, 2a and a flat part 2b are provided to the end part of the screw part 2 of the tap of the thread rolling tool which forms screws by building up the threads of male screws of female screws. The angle parts 2a, 2a are rounded to arc parts 3R, 3R having virtually on flat parts, by surface treatment such as barrel polishing or chemical polishing. As a result, there are no flat parts 2b and angle parts 2a which hardly contribute to the action of building up the crests of the blank material at the rolling and become the major factor for breakage by increasing friction with the blank material. Since the surface roughness of the screw parts 2 is also improved by said polishing, the friction with the blank material decreases, and the rolling torque decreases, hence the increase in rolling characteristic and the decrease in damaging such as breakage may be achieved.

Abstract: PURPOSE:To shorten the stabilizing time at the operation start and thus to enhance the starting characteristics for the electronic gun assembly to be applied suitably to the in-line type color picture tube, by removing part of the partition of the electron beam transmission hole. CONSTITUTION:Hole 18a-18c which are formed almost concentrically to the electron beam transmission hole of control electrode 5 are provided to grid holder 17(6) of the electronic gun assembly, and part of the partitions is removed between hole 18a and 18b as well as between 18b and 18c to form slit 21 and 22. In such constitution, holder 17 is heated up to raise up the temperature, and accordingly the heat expansion occurs near hole 18b at the center part since the temperatures at the external end part 23 and 24. However, the expansion of holes 18a-18c is absorbed both in the array direction and the direction of arrow D by narrowing slit 21 and 22. The extension of holder 17(6) is reduced extremely in the direction of arrow C. Thus, no malformation is caused virtually due to the extension in the direction of arrow A, preventing electrode 5 and others from being deformed due to the warp. Furthermore, no delay of the rise is caused after start of the operation, thus obtaining a steady picture image in a short time.

Abstract: PROBLEM TO BE SOLVED: To improve airtightness of a pressure responsive portion and performance of a main body in a pressure regulating valve by fitting an upper lid to a cylindrical fitting portion, caulking a circular projection inward, and sealing a clearance between the circular projection and the upper lid by soldering. SOLUTION: A diaphragm 11 is sandwiched between an upper lid 12 and a lower lid 22. The diaphragm 11, a fitting portion 33, and a projection 34 are simultaneously caulked. A clearance S between the projection 34 and the upper lid 12 is closed by soldering. Airtightness in a pressure responsive portion 10 is improved. The pressure responsive portion 10 is always free from influence of variation of pneumatic pressure or temperature by the use of electronic beam welding. It is not necessary to exhaust by a capillary tube, and perform sealing of gas and tube. Manufacture and operation of a pressure regulating valve 1 are facilitated compared to a conventional case. It is thus possible to improve airtightness and performance of the pressure responsive portion 10, and reduce a manufacturing cost.
