Title: Master switch for power window
Inventor: HIGUCHI MITSUTOSHI
IPC: H01H23/14
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To make whole constitution small. SOLUTION: In a master switch 1 for power windows, each window open/ close circuit for individually opening and closing the left and the right windows of the front seat and the rear seat of a vehicle can be alternatively selected by operating one rotation operating knob 3, and consequently it is unnecessary to provide an operating knob for every window open/close circuit, so that the whole constitution may be made small. A lock switch mechanism capable of locking all at once the opening and closing of each of the window open/close circuit is provided in the rotation operating knob 3. Accordingly, it becomes unnecessary to ensure the space of disposing a lock switch, so that the whole constitution of the master switch 1 may be made small.

Title: Ridge structure of roof of building
Inventor: FUNAKI GANTAN
IPC: E04D13/16
Filed: 1993-12-24
Abstract: PURPOSE:To improve the performance or generating power and external appearance, by arranging the uppermost top where solar cell modules are installed and the ridge structure composed of right and left ventilation sidefaces provided with flashings, at the ridge of a roof. CONSTITUTION:The uppermost top with a gable roof-form is used for a solar face 1' and the right and left sidefaces are used for ventilation faces 2'. The support base 3 and the wires of the solar cell modules 1 and the ventilation device 2 are contained so as not to be exposed to the outside. As the rear space (a) of module is prevented well from rain and the solar light is obstructed, the rear structure of module and the wiring materials are not required to apply a special preventive treatment. Accordingly, the heat in the module is easily removed from the ventilation faces 2' and hence, the energy conversion efficiency of the solar cells does not decrease.And since the module 1 faces two directions, the fluctuation of generated power is moderated. And when necessary, the uppermost top is made to be a pent roof facing the direction of much solar irradiance in the uppermost part, or to be a square roof facing four directions. In this way, the design is improved and also the energy conversion efficiency is increased.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which the air permeability (the permeable oxygen amount) of a porous polymer film is measured simply by providing a light oscillation means, which radiates rectilinearly advancing light, on the side of a bore hole face on the porous polymer film, and also providing a cylindrical guide, whose inner face is composed of a light absorption material, on its opposite side and the intensity detection means of light, which is transmitted through the film, at its end part.

Title: Manufacture of ceramic filter with flange
Inventor: SAKON JUNJI
IPC: B01D39/20
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To avoid the impairing of manufacturing efficiency without the generation of cracks in the body or the flange part or a gap in the joined part by baking an unbaked molding for the flange part to an unbaked molding for the body while the molding for the unbaked flange part is stuck to the molding for the unbaked body. SOLUTION: A molding 8 for the body is made to stand in the center of a form 9 with the end part to which a flange is to be joined, set under the molding 8, and a green ceramic material 11 is charged into the periphery of the molding 8 for the body and is molded under pressure using a press 10 from above. In this process, the molding of a molding for the flange part and the adhesion thereof to the molding 8 for the body are performed simultaneously to improve the dimensional precision and dispense with the finish fabrication. Next the body and the flange part, both being of the same material, are simultaneously subjected to baking so that the difference in the degree of shrinkage between the body and the flange part is eliminated.  Further, both are directly brought into tight contact with each other without the use of a joinint material and then are baked to improve the adhesive properties. In addition, both are separately molded to simplify the molding process and thereby finish their baking step at once. Thus it is possible to avoid the generation of cracks in the body or the flange part and also the generation of a gap in the joined part and prevent the manufacturing efficiency from being impaired.
