Title: X-ray image pickup panel and its manufacture
Inventor: AMITANI KOJI
IPC: H04N5/32
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray image pickup panel having a good X-ray absorption factor and easy to manufacture. SOLUTION: This X-ray image pickup panel is constituted of a photoconductive layer 62 formed on a substrate and having photoconductivity and accumulative capacitors 24 and switching elements 26 two-dimensionally arranged between the photoconductive layer and the substrate. A conversion cell 20 converting an X-ray image into an electric signal is formed with the accumulative capacitor 24, the switching element 26 and the photoconductive layer located above them. The photoconductive layer is a coated layer coated to the prescribed thickness on the substrate. The photoconductive layer is made of a photoconductive inorganic compound having a high X-ray absorption factor such as ZnO, CdS, CdSe, PbO, HgI2 , CdTe, CdZnTe, PbI2 , TlI2 , Bi12 GeO20 , Bi12 SiO20 .  Since the photoconductive layer is made of the photoconductive material having a high X-ray absorption factor, the S/N ratio of the X-ray image signal is good. The photoconductive layer is formed in a coating process, it can be easily manufactured, its manufacturing time is shortened, and the cost can be reduced.

IPC: B66D3/24
Filed: 1978-02-24
Abstract: PURPOSE: To provide a hoist with geared limit switches, in which the lift is roughly determined by a first geared limit switch and fine adjustment for on-off control of cargo raising and lowering circits is effected correctly by a second geared limit switch, whereby it is enabled to facilitate adjustment of the hoist and improve accuracy of stopping the same.  
     CONSTITUTION: A first geared limit switch 14 operates cargo raising and lowering cams 15, 16 over the entire rotation of drum 2, whereas a second operates cargo raising and lowering cams 19, 20 for each one rotation of drum 2. In raising the cargo by pushing cargo raising push button U, contact S 3  is opened at recessed portion of cam 19 for the second limit switch 18 with one rotation of drum 2, but contact S 1  of the first limit switch 14 is not opened since its cargo raising cam 15 is arranged to be operated over the entire rotation of drum 2 as described above. Thus, cargo raising operation is continued, and when the cargo comes to a predetermined stop position, both of contacts S 1 , S 3  are opened and operation of the hoist is stopped.

Title: Crossing obstructing detector
Inventor: SATO KAZUTOSHI
IPC: B61L29/00
Filed: 1989-01-31
Abstract: PURPOSE:To lower a construction cost by providing a counter for counting the number of objects existing in a railroad crossing way on the basis of the information obtained at a discriminating device for performing the discrimination with the information obtained at detectors and detecting the existence of the objects in the railroad crossing way by the counted result. CONSTITUTION:A discriminating device E discriminates whether objects advanced in or out a railroad crossing way from the information obtained at detectors A, B, C, D. A counter F counts the number of objects which advanced into the railroad crossing on the basis of the information obtained at the discriminating device E, collates the numbers of the objects which advanced in and out, judges the existence of objects in the railroad crossing way if the numbers of the objects do not coincide, and outputs its judgement to an output device G. The output device G performs obstructing detecting output in case the counter F outputs the existence of objects in the railroad crossing way despite the blocking of the railroad crossing. The obstruction remaining in the railroad crossing way at the approaching time of a train or a rolling stock can be thus detected automatically.

Title: Manufacture of laminated piezo-electric element
Inventor: IMOTO YASUO
IPC: H01L41/22
Filed: 1993-02-08
Abstract: PURPOSE:To reduce defectives and manhours and eliminate environmental problems in the manufacture of laminated piezo-electric elements. CONSTITUTION:Piezo-electric materials 11 and internal electrodes 12 are alternately laminated to manufacture a laminated piezo-electric element. After the slicing process in the manufacture, at least the side of the element where an internal electrode 12 is exposed is subjected to shot blasting. This makes unnecessary a lapping process to remove scrapings from sliced faces. In addition the end of the internal electrode 12 is projected from the level of the end face of the piezo-electric material 11. This increases the surface area of the internal electrode 12, and provides reliable connection with external electrodes.

Filed: 1995-02-08
Abstract: PURPOSE: To eliminate the risk of damaging or injurying a rim valve due to slippage of a chain band when fitting a snow chain to a wheel and also to do away with designing restrictions by arranging a rim valve on either the right or left side of a spoke and forming the spoke so that the rim valve may be housed inside the side projecting surface of the spoke. CONSTITUTION: Not only is a rim valve V arranged on either the right or left side of a first spoke Sp1 , it is formed so that its exposed part may be housed inside the side projecting surface of the spoke Sp1 . Mutual interference of a chain band CB and the rim valve V is evaded and damage or injury of the rim valve V is nipped in the bud should a snow chair SC (therefore, the chain band CB) make a circumferential slippage with respect to a wheel W by receiving rotational drive force from a rear wheel 1r, even if the chain band CB is run through a gap S13 between the first and a second spokes, because the chain band CB making an approaching move towards the rim valve V side can certainly be regulated by the first spoke Sp1 .

Title: Process and apparatus for surface modification of fluororesin
Inventor: INAZAKI SATOSHI
IPC: C08J7/00
Filed: 1993-02-08
Abstract: PURPOSE:To easily and uniformly make the surface of a fluororesin hydrophilic. CONSTITUTION:The apparatus consists of an ultraviolet source and a container for holding a fluororesin and highly pure water to be brought into contact with the resin and an optical means for irradiating the desired part of the contact surface between the fluororesin and the water with the light from the ultraviolet source. When the fluorinecarbon covalent bonds of the fluororesin are broken by ultraviolet light, the dissociated fluorine atoms are bonded to the hydrogen atoms of water, while the resulting hydroxyl groups are bonded to the carbon atoms at which the covalent bonds have been broken. Since the highly pure water is in contact with the fluororesin, while it is kept uniform in composition, the fluororesin can be made uniformly hydrophilic. Since the highly pure water has a good light transmittance, the ultraviolet irradiation can be performed through the water. Therefore, the surface of the fluororesin can be made hydrophilic even when it is thick.
