Title: X-ray image photographing apparatus
Inventor: TAMURA JOICHI
IPC: A61B6/00
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To dispense with the resetting of a compensation means to enhance operability by controlling a rotary means rotatable around the straight line connecting the compensation means and imaging means provided to a freely rotatable C-shaped arm. SOLUTION: Two operators adjust the position of a compensation means 102 on the supposition that a C-shaped arm 105 is inserted from the head direction of a subject. Actually, the support arm 106 to which the C-shaped arm 105 is connected is rotated by 45 deg. within the plane becoming horizontal with respect to a floor surface to insert the subject into the C-shaped arm 105. Therefore, an angle-of-rotation detection means 113 detects the angle of rotation of 45 deg. of the support arm 106 and outputs the 45 deg.-rotation of the support arm 106 to a control means. The control means controls a rotary means to rotate the compensation means 102 by 45 deg. in the direction reverse to the rotary direction of the support arm 106. Since the rotation of the compensation means 102 is canceled, the positional relation between the compensation means 102 for correcting X-ray absorption difference and the subject is not changed and it is unnecessary to reset the compensation means in such a state that the C-shaped arm 105 is inserted from the head direction of the subject.

Abstract: PURPOSE:To speedily carry out the grinding work with high precision by stopping the grinding operation and detecting the abrasion quantity of a grindstone from the measurement value of a noncontact type distance meter for a standard gauge on a table and keeping the grinding operation starting position at a constant position. CONSTITUTION:When grinding operation starts, a table 1 moved in reciprocation right and left, and noncontact distance meter 5 alternately measures the distance between a standard gauge 4 and a workpiece 2 to be ground by a grindstone 3, and the value is input into a controller 6. The table 1 is roughly fed until the deviation value between the both becomes the prescribed value close to zero, and when the prescribed value is reached, fine feed is carried out, and when the deviation value becomes zero, the grinding for the workpiece 2 i suspended, and the table 1 is returned to the original point position A. Then the abrasion quantity of the grindstone 3 is detected from the measurement value of the distance meter 5 for the standard gauge 4, and if said quantity is over a set value, the distance meter 5 is shifted upwardly by the distance corresponding to the abrasion quantity from the initial set position together with the table 1 by a shift mechanism 5-1, and the grinding operation starting position is kept constant. Thus, safe and speedy grinding work with high precision can be carried out.

Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a cemented carbide capable of maintaining self-lubricity even under ultrahigh loading and high temp. conditions by mixing a powder of molybdenum disulfide with a powder of cemented carbide consisting of Co and WC and applying hot isostatic pressing to the resultant powder mixture. SOLUTION: Molybdenum disulfide powder is added by about 1-15 pts.wt. to 100 pts.wt. of alloy consisting of about 30-50wt.% Co and the balance WC, etc., and these are mixed. The resultant powder mixture is put into a hermetically sealed vessel and hot isostatic pressing is performed, by which a compact of cemented carbide with self-lubricity can be obtained. In the case where a Co-WC alloy is used as the cemented carbide, appropriate hot isostatic pressing conditions are as follows: temp., 1200-1400 deg.C; pressure, (500 to 2000)kg/cm<2> ; time, 1-10hr. The maintenance of the resultant sintered compact of the cemented carbide is facilitated because a lubricant always appears at a renewed surface even if the surface of the sintered compact is worn away and self-lubricity can be maintained.
