Abstract: PURPOSE:To improve rigidity, reduce the number of welding spots, eliminate stress relieving and reduce the cost of production by attaching a necessary reinforcing material to the inner part of a monocoque type outer plate forming a rim part in each of proper spots such as a peripheral edge, an opening edge and a butting edge by means of bending. CONSTITUTION:A side body structure 1 is mainly divided into blocks 13-20, and each window column 40 required for these blocks is combined together.

IPC: B41J2/36
Filed: 1993-03-26
Abstract: PURPOSE:To make a dot printer quickly start printing by providing a printing dot number counting device which calculates a total dot number when writing print data for one run of a print head into a printing buffer is completed. CONSTITUTION:When a communication controller 5 receives printing data from a host computer 11, a CPU 1 develops the printing data into a dot pattern and stores it in a printing buffer in a RAM 3 as printing dot data after once storing the printing data in a receiving buffer. The number of dots to be printing is added by an adder every time the printing dot pattern is stored in the printing buffer in a unit of 8 bits, and when the printing dot data for a line are stored in the printing buffer, the adder outputs the total dot number. Thereby, the CPU 1 controls a printing controller 4 and a mechanical controller 6 for printing one line based on the total dot number, so that a rise in temperature of the print head is restrained within an allowable temperature range.

Abstract: PURPOSE:To promote the concentration efficiency of a magnetic flux denpending on the size of magnetic gap length and obtain compact power saving rotary anode type x-ray tube equipment by mounting a material ring of high permeability on the external surface of a permanent magnet. CONSTITUTION:Suppose that an instantaneously energizing stabilization control system is selected, when an external force is applied to rotor 11 and the gap length between this rotor 11 and the protruded thick section 100a of annular members 134a and 134b of high permeability is reduced, a stable magnetic support is achieved by energizing a coil 30 by means of a stabilizing control unit 51, applying such a force that reduces the gap length between the other protruded thick section 100b located at a different position from the protruded thick section 100a by 180 degrees and rotor 11, matching the magnetic force of permanent magnets 33a and 33b with the external force, and creating the new equilibrium state of the rotor 11. When a magnetic force is controlled on a straight line that provides connection between the protruded thick sections 100a and 100b like this, the magnetic force can effectively be controlled by concentrating it near this straight line.

Title: Ct scanner
Inventor: SAITOU KIYOTO
IPC: A61B6/02
Filed: 1978-06-09
Abstract: PURPOSE: To secure corection of the increment of the slice width at the fringe area  caused by the central radiant rays of the fan beam by decreasing the beam thickness at the fringe area, and thus to ensure the substantial uniformity for the slice  width.  
     CONSTITUTION: Fan beam 16a radiated from radiation source 14 transmits through  tested object 15 and enters the detector. in this case, the radiant rays at center part  19 of beam 16a always pass through the center part of the fault surface to contribute to the whole fualt surface, but the radiant rays at fringe part 20 contribute  only to the circumference part of the fault surface. As a result, the cross-section of  the fault surface becomes thin at the center part and thick at the fringe part owing  mainly to the radiant rays at the center part. This can be corrected by decreasing  the deflecting width and thickness of beam 16a gradually from the center to fringe  part. As a result, the thickness of the fan beam can be changed uniform substantially, and accordingly the pickup leak part can be solved in the case of the continuous  shooting of several slices. And furthermore, the double exposure can be reduced.

IPC: G01M11/00
Filed: 1984-04-06
Abstract: PURPOSE:To easily measure the parallelism of a parallel surface with high precision and to scan and measure undulations of the parallel surface by arranging a reflecting mirror at right angles to the optical axis of a laser light source and detecting deviation in the incidence position of reflected light which is transmitted through a sample. CONSTITUTION:When a light beam is incident on a nearly parallel surface 17 with a fine angle theta at an angle theta1, the angle epsilon between the incident light beam and projection light beam is fixed even when the surface 17 is rotated by a fine angle. The sample 20 which transmits light and has a nearly parallel surface with a fine angle theta is inserted into the optical path between the laser light source 18 and reflecting mirror 19. The light beam transmitted through the sample 20 changes in traveling direction by the angle epsilon and is reflected at a point A on the mirror 19 and then transmitted through the sample 20 again to travel at an angle 2epsilon to the projection light and reaches a point B. The extent (d) of deviation is obtained from d= 2(l1+l2)(n-1)theta, where l1 and l are distances between the sample 20, and light source 18 and mirror 19 and (n) is the refractive index of the sample 20. For the purpose, a beam splitter 21 and a qarter-wavelength plate 22 re provided on the optical path, and the reflected light is made incident on a beam position detecting element 23 to read the output signal of the extent (d) of deviation, so that a measurement is easily taken only by placing the sample on the optical path.
