IPC: G01T1/29
Filed: 1984-01-13
Abstract: PURPOSE:To form a picture prevented from dispersed lines and provided with high resolution by detecting linear X rays from a line detector by a surface detector. CONSTITUTION:Linear X rays are moved relatively to a subject 3 in the linear direction, i.e. the direction crossing with the length direction of slits 2A, 2B, the slits 2A, 2B are fixed so that two-dimensional scanning is executed and the subject 3 is moved together with a photosensitive body 4 in the solid line arrow direction. Or, the subject 3 and the photosensitive body 4 are fixed and the slits 2A, 2B are moved in the dashed arrow direction while keeping straight arrangement with the X-ray source 1. Thus, the X-ray transmission image of the subject 3 is recorded on the photosensitive body 4. The recorded X-ray transmission image scans laser light 5A to be excited light from a laser light source 5 on the photosensitive body 4 two-dimensionally by a galvanometer 6. Since the transmission image of the subject 4 is obtained by using the linear X rays, the X-ray transmission image prevented from dispersion lines can be obtained, and since the picture is recorded on the surface-like photodetector, a picture having high resolution can be obtained.

SOLUTION: SiCl4 is brought into contact with NH3 in a liq.-phase or gaseous-phase state by the thermal decomposition of an imide almost at ordinary temps. to form Si(NH)2 by an interface reaction, the Si(NH)2 is heated to 1200-1500 deg.C in a non-oxidizing atmosphere to conduct thermal decomposition and crystallization, and a mixture of the Si3N4 grain and NH3 is obtained. The mixture is then heated in the atmosphere for at least 40 min at least 400 deg.C, e.g. 500-600 deg.C. Consequently, NH3 is decomposed into N2 and H2 and separated and removed from the Si3N4 grain. The Si3N4 grain is mixed in a plating soln. to obtain a composite plating soln., hence the Si3N4 grain is efficiently coprecipitated in a metallic matrix without being hindered by NH3, and a composite plating film is obtained.

Title: Control system for radio transmitter of subordinate station
Inventor: TSUBOI TOSHIHIDE
IPC: H04B7/24
Filed: 1981-01-19
Abstract: PURPOSE:To perform secure interruption from one subordinate station by stopping the transmission of the radio equipment of another subordinate station by a timing pulse generated by the radio equipment of the latter subordinate station, in a radio transmission controlling system for the interruptible subordinate stations. CONSTITUTION:In the radio equipment of a master station, an interruption clock pulse generator 3 generates a constant timing pulse, which is ANDed with the busy signal H of a calling subscriber of the master station by an AND circuit 4 to be transmitted for a constant time of an interruption permit signal I. At a subordinate station on a duplex transmission system, transmission is stopped for the time when the interruption permit signal I is detected in a busy state. At a subordinate station on a two-wave press-to-talk system, a pulse generating circuit 104 is controlled by the rise of the detection of an interruption synchronizing signal J to obtain clock pulse signal K which synchronizes with constant timing. Further, pulses with constant time width which repeats at constant timing are generated by the pulse signal K, and consequently transmission is forced to stop repeatedly even when the press-to-talk type subordinate station is busy.
