Abstract: PROBLEM TO BE SOLVED: To obtain a new fluorine-containing porphyrin complex useful as a contrast medium having a sufficient contrast ability in a physiologically acceptable concentration region and capable of giving image information useful for diagnoses in a nuclear magnetic resonance contrastradiography using<19> F as a detection nucleus. SOLUTION: This is a complex of formula I [R is a group of formula II or III (X is hydroxyl group, amino or the like): Z<a+> is an oriented paramagnetic metal ion], for example, 5,10,15,20-tetrakis 4-[2-3-sulfopropyloxy)hexafluoro-2- propyl]phenyl] porphyrin magnesium complex. The complex is obtained by condensing 3,5-bis(2-hydroxyhexafluoro-2-propyl)benzaldehyde with pyroole, oxidizing the produced porphyrinogene with a quinone oxidizer, introducing a protected hydrophilic portion having a releasing group in the form of an ether bond to the hydroxyl group of the fluorosynthon portion of the obtained porphyrin ring, removing the protecting group, and subsequently complexing the obtained ligand compound with a metal ion.

Abstract: PURPOSE:To obtain a satisfactory optical performance even in case of the use of a material, which is relatively easy to polish and has a lower refractive index and less disperses the light, as a negative lens in a first lens group by satisfying specific conditions with respect to zoom lens which is provided with two lens groups, namely, the first lens group having a positive refracting power and a second lens group having a negative refracting power and changes the interval between both lens groups to vary the power. CONSTITUTION:This lens system satisfies conditions of inequalities (1)-(7) where f1i, F1, N11P, N12N and nu12N, and N13P are the focal length of the 1i-th lens group, the focal length of the first lens group, the average value of the refractive index of the material of a positive lens in a 11th lens group, average values of the refractive index and the Abbe's number of the material of a negative lens in a 12th lens group, and the average value of the refractive index of the material of a positive lens in a 13th lens group respectively. Thus, a satisfactory optical performance is obtained throughout the variable power range though the material which is relatively easy to polish and has a low refractive index is used as negative lens in the first lens group.

Title: Parallel flat same color pair arranged cable
Inventor: TADA KAZUMITSU
IPC: H01B7/08
Filed: 1990-01-31
Abstract: PURPOSE:To enhance operational facility particularly at the time of wiring two lead wires in a pair by coloring two adjacent lead wires in a parallel flat cable in the same color, and repeating various colors. CONSTITUTION:Each pair of wires in a parallel, flat cable are made identical in color. For example, since jigs for printed circuit board inspectors after packaging of electronic parts must be prepared for each kind of board, contact probes 4 and 13 constitute one pair so that the parallel flat cable lead wires 7 and 8 for wiring the probes are made identical in color. Another pair of parallel flat cable lead wires 11 and 12 are made identical in color different from the above-mentioned color. Therefore, any confirmation of a pair of wires can become unnecessary, and moreover, wiring efficiency of the jigs can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To prevent invasion of water into an outer frame from around a hook part to hold a cover body in a closed condition. SOLUTION: A clamp main body 131 on the side of a cover body 121 is engaged with a hook part 137 on the side of an outer frame 52, so the cover body 121 is held in a closed condition. The hook part 137 is formed on an inner pot support body 71 as a separate body from the outer frame 52 integrally having an upper wall part 54, an outer wall part 55, and an inner wall part 56. The inner pot support base 71 is assembled to be engaged in an assemblage recessed part 61 formed in the outer frame 52. Wall parts 62, 63 forming the assemblage recessed part 61 have no through holes or gaps communicating the inside of the outer frame 52 with outer side. Invasion of water can thus be prevented. The inner pot support base 71 can be engaged with the assemblage recessed part 61 only by slide action from the back side forward.

Title: Shifting state discriminating device of parts to be shifted
Inventor: AKAMA MASARU
IPC: B65G47/24
Filed: 1981-02-14
Abstract: PURPOSE:To exactly discriminate a shifting state at all times, by mutually deflecting and placing 2 photosensitive elements opposed to a light source for detecting a shifting state of parts to be shifted, in the direction which is capable of discriminating the shifting state, from the contour of a front end of the parts to be shifted. CONSTITUTION:2 photosensitive elements 4a, 4b opposed to a light source are placed so as to be deflected by an angle alpha from the contour of the end of parts (m) (full line) which are carried on a chute 1a. When the photosensitive element 4a is shaded by the parts (m), an input terminal J and K of an FF17 become ''1'' and ''0'', respectively, through a transistor (TR) 11 and NOT elements 13, 14. Subsequently, when the photosensitive element 4b is shaded, a terminal C becomes ''0'' through a TR12 and NOT elements 15, 16, and an output of a terminal Q becomes ''1''. It is detected that the parts (m) are in a state that its  front is the head. Even when the parts have jumped up as shown by a dotted  line, the same result is obtained. In this way, the shifting state is discriminated  exactly at all times.
