Title: Electroslag welding method of tee joint
Inventor: OONO KATSUE
IPC: B23K25/00
Filed: 1980-08-20
Abstract: PURPOSE:To cause convection of molten slag and prevent the defect in bead shape by placing straps in such a way that the bead shape forms a rectangular equilateral triangle shape, and curving the inside surfaces of the end parts of the straps. CONSTITUTION:The inside surfaces of the end parts of the straps 4, 5 of a tee joint in contact with welding materials 1 are hollowed to curved surfaces. At this time, the angle alpha that the curved surfaces and the surfaces of the materials 1 form is set larger than 45 deg. and smaller than 90 deg. and the radius of curvature is set at about 4mm.. If the radius of curvature is smaller than this, the convection and circulation of molten slag are poor, and the defects such as overlaps are easy to occur. If it is larger than this, the defects such as undercuts are easy to occur on account of the solidification of molten slag. If the inside surface shapes of the straps 4, 5 excluding their end parts are formed as curved surfaces projecting in the central parts, and the height of reinforcement of weld is lowered, the saving of welding materials and the reducion of welding time are achieved.

Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase a reflectance of a reflecting optical element by rotating polarized light of an LCD panel, and prevent light utilization efficiency from decreasing by arranging a phase plate at a front stage of the reflecting optical element. SOLUTION: A CPU board 2 converts video RGB signals supplied from an external personal computer 1 into digital signals by an A/D converter, and also transmits a synchronizing signal to an LCD panel 3 by converting it into a timing signal by a timing circuit. Here, a shift register fetches the RGB signals for each pixel based on the timing signal, and also generates a horizontal synchronizing signal and a vertical synchronizing signal by a dividing circuit, and further, displays a video in a dot matrix system. This video is reflected by a combiner 6 via an optical member 5 with illumination of backlight 4 and is reflected while being overlapped back ground. Then, a phase plate 7 rotates the polarized light of the display light from the LCD panel 3, therefore, the reflectance of the combiner 6 becomes high.

Title: Relief valve and brake device
Inventor: KOJIMA HIROMASA
IPC: B60T8/34
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To keep the opening pressure of a relief valve at a constant value without being influenced by the liquid pressures of two chambers separated by a valve seat. SOLUTION: A first piston 22, a first spring 24, a second piston 27, and a second spring 31 are arranged in series in a cylinder 21. The second piston 27 is provided with pressure receiving surfaces 27f and 27g to receive a pressure such that a hydraulic pressure in a third chamber 28 communicated with a second chamber 26 is moved in a direction in which it is separated away from the first piston 22. Since, when a hydraulic pressure in the second chamber 26 is increased, the pressure receiving force in a closing direction of the first piston 22 is increased but since the energization forces in an opening direction of the first and second springs 24 and 31 on the first piston 22 are reduced, a force exerted in a closing direction on the first piston 22 is kept at a constant value. This constitution keeps the opening pressure of the first piston 22 at a constant value.

Title: Black toner for color image

IPC: G03G9/09
Filed: 1989-05-11
Abstract: PURPOSE:To obtain a black toner for forming a color image high in image density in deep color parts at the time of using a black toner, and good in the gradation of gray in halftone parts by using a specified carbon black as a colorant and specifying the apparent viscosity of a toner. CONSTITUTION:Carbon black is used as a colorant, and it has an average parti cle diameter of 50 - 80mum, an oil absorption of 50 - 100ml/100g, a pH of 6.0 - 9.0, and an electric resistivity of 0.5 - 1.0OMEGA.cm, and the toner has an apparent viscosity of 10<4> 0 10<6> poise at 90 deg.C and that of 5X10<3> - 5X10<5> at 100 deg.C. If the carbon black has an average particle diameter of <=50mum, dispersion deteriorates and fog is made liable to occur, and it is necessary to maintain the apparent viscosities in the range in order to give offset resistance to fixing rolls, and if the apparent viscosities are out of these ranges, both of the requirements of color mixing and offset resistance cannot be satisfied, and further, the electric resistivity of the carbon black affects the electric charge leakage characteristics, and if the oil absorption of its factor gets out of this range, the toner cannot be sufficiently charged, thus permitting sharp copied images high in image quality to be obtained.
