Title: Large screen display device
Inventor: YAMAWAKI KATSUMI
IPC: G03B21/62
Filed: 1987-11-20
Abstract: PURPOSE: To provide a display device which does not lose the continuity of a screen and has excellent visibility by mounting a light transparent holding plate having the same coefft. of expansion as the coefft. of expansion of plural screen members at the front surface side of a casing and holding the plural screen members by this light transparent holding plate from its rear surface side. CONSTITUTION: The light rays from projectors 22, 23 arrive at the rear surface of the light transparent holding plate 28 via mirrors 26, 27, further, pass the inside of the light transparent holding plate 28 and are projected on the screens 10, 12. At this time, silicone rubber 32 is packed and, therefore, the leakage of the light from gaps does not arise. When the temp. in the casing 9 rises, the thermal stresses tend to be generated by the tightening of screw members 31 but the generation such thermal stresses does not arise as the coeffts. of thermal expansion of the screens 10, 12 and the light transparent holding plates 28, 30 are the same. The expansion in a vertical direction can be dealt with that the through-holes for the mounting screws 29 which are disposed on the front surface side of the frame 1 are formed sufficiently large.

IPC: E02D5/44
Filed: 1986-12-10
Abstract: PURPOSE:To permit a deep foundation pile to be constructed with good efficiency by a method in which deep foundation bottom is excavated while supporting the pit wall by concrete with side footings and then concrete is placed. CONSTITUTION:A deep foundation 4 is excavated to form a wall, and a number of horizontal pits 12 are excavated on the lowest bottom. Concrete 13 is placed into the pits 12 to form the concrete 13 with side footings.

IPC: G09G5/10
Filed: 1988-11-21
Abstract: PURPOSE:To display a picture with the gradation of high quality in a simple circuit constitution by obtaining not only a luminance corresponding to display data in every field but also an about half low luminance of this luminance in every other field. CONSTITUTION:Not only the operation to obtain the luminance corresponding to display data in every field but also the operation to obtain the about half luminance of this luminance in every field are performed to increase the numbers of stages of luminance. Consequently, two kinds of luminance, namely, the luminance corresponding to display data and the about half low luminance of this luminance are obtained when display data is received in every field and is received in every other field. Thus, the control is performed by the simple circuit constitution though the number of bits D0, D1, and D2 of display data is increased because of the increase of the number of stages of gradation display.

Title: Brake actuator
Inventor: DANKAN ASHIYUREI ABUEYAADO
IPC: F16D65/14
Filed: 1986-12-10
Abstract: The present invention relates to a brake actuator for use in a disc brake, the brake actuator incorporating an automatic adjuster mechanism to take account of friction pad wear. In certain known brake actuators a clutch mechanism comprising one or more clutches is used to provide for the required control of the rotational movement of a threaded adjuster sleeve (19) in which a tappet (21) is located. These clutches are located around the outside surface of the adjuster sleeve (19) and thus, due to overall spatial requirements within the actuator (1), the outside diameter of the adjuster sleeve (19) and as a result, the diameter of the threaded bore in the adjuster sleeve (19), have to be limited in size. The threaded tappet (21) thus comprises an enlarged diameter head region and a reduced diameter threaded region. Due to the limited diameter of the tappet (21), the tappet (21) can tilt or be damaged, resulting in premature and/or even pad wear. The present invention provides a brake actuator comprising a drive shaft 93) rotatably supported in an actuator housing (1) and coupled to an internally threaded adjuster sleeve (19) by coupling means (7) which convert rotational movement of the drive shaft (3) into axial movement of the adjuster sleeve (19). The internally threaded adjuster sleeve (19) is retained against rotational movement and is screw threadedly engaged with a hollow tappet (21) within which a clutch mechanism (23, 35) for interconnecting the drive shaft (3) and tappet (21), is located. The clutch mechansim (23, 25) is thus located within the hollow tappet (21) so that the diameter of the threaded connection between the tappet (21) and adjuster sleeve (19) can be optimised to at least reduce the problems of premature and uneven pad wear inherent in previous constructions.

IPC: F02M63/02
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To operate a high pressure pump by use of a small-sized and low- priced solenoid valve by holding a closing body in a valve open position by a valve rod of a solenoid valve when an electric current is applied to a magnet, and causing the high pressure force-feed start of the high pressure pump by interception of the magnet of the solenoid valve. SOLUTION: A suction pipe 8 is guided to a working chamber 5, a solenoid valve 9 is inserted in the suction pipe 8, and a valve closing body 10 formed as a ball of the solenoid valve 9 can be lifted from a valve seat of the valve closing body 10 only by the inlet pressure of the suction pipe 8 against the force of a valve spring 11. The valve closing body 10, the valve spring 11 and the valve seat 12 form a check valve. The valve closing body 10 reaches the valve seat 12 according to the force action of the valve spring 11 and the force of fuel jet so that the solenoid valve 9 is closed. In the working chamber 5 of the high pressure pump 1, pressure formation is started and diesel fuel is forcefed to a high pressure accumulator 2 through the opened check valve 7 and the high pressure pipe 6. Thus, the high pressure pump can be operated by a small-sized and inexpensive valve.

Abstract: PURPOSE: To produce a part containing Fe for metallurgical joining to an aluminum casting by successively forming a Fe-Al intermetallic compound layer, an aluminum coating and a Zn alloy coating on a part containing Fe.  
     CONSTITUTION: A part 10 containing Fe is immersed in a molten Al bath at 1000-1500°C for 1.5-2min, an Fe-Al intermetallic compound layer 12 of about 0.0005in thickness is formed on the part 10 containing Fe. Successively, when taking out the part 10 containing Fe, Al 2 O 3  film is produced on the surface of a molten Al coating 14 covering the part 10 containing Fe. While maintaining the molten Al coating 14 is a molten state, by immediately immersing in a molten Zn alloy bath (Al contact 1-40wt.%) of 720-1000°F for rapid cooling, the Al 2 O 3  film is floated on the An alloy bath surface to be removed. By this method, a protective An alloy coating 16 (about 0.001-0.003in thickness) is formed on the Fe-Al intermetallic compound layer 12 through the Al coating 14 (about 0.001-0.004in thickness), thus the part 10 containing Fe for metallurgical joining to an aluminum casting is obtained.
