Title: Groove machining method for collection mirror
Inventor: ISHIKAWA MICHIO
IPC: B24B19/02
Filed: 1987-07-07
Abstract: PURPOSE:To prevent the occurrence of tipping, residual processing distortion, and unevenness in the depth of a groove and to form the high-precise shape of a groove, by a method wherein, by using a single or a combination grinding stone, a cutting amount of a grinding stone is provided in a manner to be divided in many stages based on the given depth of a groove. CONSTITUTION:When groove machining is applied on a collecting mirror 1 made of an Si crystal by 2-stage cutting through the use of, for example, a single grinding stone 4, the depth of a first stage groove 2 is set to d1=6.5 mm and the depth of a second-stage groove 3 to d2=0.2 mm, and a feed speed is set to a value being approximate two times as high as that of a conventional first stage machining. In which case, machining distortion of a groove bottom part, occurring at a first stage machining time, is higher than that of a conventional method, but since the distortion is removed at a second stage machining time, it is enoughly decreased. Further, since a final cutting amount is low, coarseness of a machined surface and wear of a grinding stone are low, and groove precision is improved. This method prevents the occurrence of a trouble, e.g. tipping, residual machining distortion, unevenness in the depth of a groove, which heretofore occurs, and enables provision of the high-precise shape of a groove.

Title: Discharge machining device
Inventor: ISHIHARA SHOJI
IPC: B23H7/36
Filed: 1990-06-29
Abstract: PURPOSE:To obtain a small device coping with the negative pressure and abnormally high pressure due to the large vertical motion of a large electrode at a low cost by assembling a pressure control valve and a machining liquid accumulator into a jet circuit feeding a machining liquid to the gap of an inter-electrode section through holes of an electrode. CONSTITUTION:A pressure control valve 10 and a machining liquid accumulator 11 are assembled into a jet circuit feeding a machining liquid to a discharge machining inter-electrode section. When an electrode 1 is lifted, negative pressure, i.e., the machining liquid deficient state, is generated in the inter-electrode section, a large quantity of the machining liquid is discharged to the jet circuit from the machining liquid accumulator 11, thus the negative pressure of the inter-electrode section is prevented. When the electrode 1 is lowered, the abnormally high pressure state is generated in the jet circuit of the machining liquid, the pressure control valve 10 provided on the jet circuit of the machining liquid is operated, the abnormally high pressure is avoided, and stable machining and circulation of the machining liquid are performed. Troubles due to the machining liquid deficiency and abnormally high pressure in the jet circuit can be prevented, it is not necessary to select the whole machine of the higher type by one rank, and an inexpensive device is obtained.

IPC: B05D7/00
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent color-coated face from being stained and damaged and to prevent coating operation from being retarded caused by rain fall, snow fall, etc., by a method wherein ground coloring is applied onto the whole face of the exposed face above the ground in factory operation and after a concrete block is placed on a site to be installed, a top coloring is applied onto the ground coloring by on-the-spot operation. SOLUTION: At first, ground coloring is applied onto the whole face of the exposed face above the ground in factory operation. At this time, a concrete block A is an unfinished half-finished product. Then, after this concrete block A is carried to the actual spot and this is laid, a top coat coloring 3 is applied onto the ground coloring 2 by on-the-spot operation. Therefore, as two coatings, namely, the ground coloring 2 and the top coat coloring 3 are performed, a color coating with good finish being based on the basis of coating can be obtd. In addition, as the top coat coloring 3 is applied after laying operation is performed on the actual spot, there exists no possibility of generating staining and damage caused by earth and sand. In addition, as the ground coloring 2 is applied, it is possible to prevent water such as rain from sinking into the base skin.
