Title: Gas breaker
Inventor: HOSOMI MAMORU
IPC: H01H33/64
Filed: 1989-11-24
Abstract: PURPOSE:To miniaturize the whole device by constituting a gas breaker so that a movable contact and the tank inner wall of a breaker can be connected with dielectrics and a condenser relaxing transient recovery voltage at the time of breaking can be formed inside the tank. CONSTITUTION:A movable side flange 8 and the inner wall of a vessel 1 are electrically connected with plural cylindrical dielectric 21 having the main component of e.g. barium titanate and strontium titanate, etc., and a ceramic condenser is formed between the flange 8 and the inner wall. That is, the said connection finally forms the condenser 15' having both poles of the movable side flange 8 and the inner side of the vessel 1. The condenser 15' has the same function as that of an outer condenser 15 connected between the vessel 1 and a bushing terminal 3c in a circuit point of view. Because the dielectric 21 has very hard and brittle properties, rod-like one, retaining strength by coating around it with cylindrical synthetic resin, is actually used in many numbers as necessary. This permits the miniaturization of the whole device compared to condenser arranging on the tank outside.

Title: Image forming device
Inventor: YANO HIDETOSHI
IPC: G03G15/01
Filed: 1990-11-13
Abstract: PURPOSE:To maintain a position of a developing electrode to an image carrier and each surface interval of both of them constant by shifting a developer receptor selectively to a position where the cover member surrounds a rotating field generating means together with a developing electrode member and forms a developer carrier part. CONSTITUTION:Each of developer receptors Y, M, C available for development are shifted to a position where the cover member 6 surrounds a rotating field generating means 5 together with a developing electrode member 3 and forms a developer carrier part by a developer receptor supporting means 23, and a developer is conveyed on a developer carrier part at a rotating magnetic field by the rotating field generating means 5. Accordingly, the developer is fed to the surface of an image carrier 1 on the developing electrode member 3, thus it acts so as to do development. Therefore the developing electrode member 3, forming developing area in opposite to a surface of the image carrier 1 is unnecessary to change any position to the image carrier 1 at time of this changeover. With this constitution, a position on the developing electrode to the image carrier 1 and each surface interval of both of them are kept constant in this way.

Title: Antenna switching system
Inventor: KURIYAMA MASARU
IPC: H04B5/00
Filed: 1988-12-03
Abstract: PURPOSE:To shorten a time, in which carrier intensity is lowered, by switching plural antennas, which are set at the interval of a prescribed distance in a moving body, only when the carrier intensity is lowered for the prescribed time. CONSTITUTION:When a moving body 4 moves from the side of a host station 1 to a right direction in a figure, an antenna 9 arrives at an interval 3 of a linear wave source 2. When the moving body 3 is further moved, the intensity of the carrier to be received by the antenna 9 goes to be <= a prescribed value and a slave station 7 recognizes such a condition and changes an antenna switcher 5 over to an antenna 8 side. At such a time, the antenna 8 does not arrive at the interval of the linear wave source 2. Then, after a time to be determined by the switching speed of the antenna switcher 5, signal transmission can be executed again through the antenna 8.

Title: Artificial bone
Inventor: NISHIHARA KATSUNARI
IPC: A61F2/28
Filed: 1993-12-07
Abstract: PURPOSE:To effectively disperse stresses and to maintain the modification of a bone over a long period of time by forming the surface of an artificial bone to be joined in the form of adhesion of connective tissues (sharpey's fibers) to the intrinsic bone to a corrugated cylindrical form alternately formed with build-up parts and recessed parts. CONSTITUTION:The build-up parts 2 and recessed parts 3 are alternately disposed on the surface of the stem of an artificial thigh joint 1 to form the surface to the corrugated form as a whole. The stem is formed to the corrugated cylindrical shape in such a manner, by which the direct transmission of stresses from the artificial bone to the surrounding bones is averted and the stress dispersion and homoquenty to the surrounding bones are effectively attained. As a result, a promating effect on extremely thin fibrous tissues of the living body around the artificial bone is obtd, and the artificial bone is stably fixed in the body; in addition, the neogenesis and modification of the bone relating to the surrounding bones of the artificial bone are maintained stably over a long period of time. Further, cortical bones are formed on the outer layers of the fibers and, therefore, the modification of the osteotissues is maintained over a long period of time even under interative load.

Title: Apparatus for producing electrolyzed water
Inventor: KAKINUMA KEIJI
IPC: C02F1/46
Filed: 1994-11-16
Abstract: PURPOSE: To remove a calcium deposit near the upper part of a cathode cell and in a cathode discharge pipe and to protect the electrodes of an ORP meter by lowering pH of cathode water discharged from an anode cell by adding simultaneously electrolite and an organic acid to raw water during back washing of an electolyzer. CONSTITUTION: Back washing is conducted while electrolyte being added. A part of raw water flows to an addition cylinder 16 through a water supply pipe 17 when a valve 19 is opened. When a chemical is placed in the addition cylinder, the chemical is dissolved to be supplied from an outflow pipe 18 to an electrolyzer through water supply pipes 11, 12. In this process, the chemical added into the cathode cell can dissolve a calcium deposit in an area with a smaller electrolytic current density close to the upper part of the cathode cell which is formed during a normal operation and in a cathode discharge pipe. Besides, cathode water discharged from an anode cell is neutralized to decrease pH to prevent the functional deterioration of the electrodes of an ORP meter installed in an anode pipe.

Title: Controlling method for position of semiconductor chip
Inventor: TSUBAKI KAZUHIKO
IPC: H01L21/68
Filed: 1989-11-27
Abstract: PURPOSE:To prevent the cutout of the end of a semiconductor chip by using a control jig for so processing the pressing face in contact with the chip as to become parallel to the side face of the chip at the time of controlling the position. CONSTITUTION:An L-shaped control jig 2 is so disposed on a base as to hold a semiconductor chip 1 on the extension line of the diagonal line of the chip 1. In this disposition, the jig 2 is moved in a moving direction indicated by '3' to press the chip 1 to another one control jig. If individual chips 1 are divided from a semiconductor substrate by using a cleavage, it is general that the side face 5 crosses a main face at an angle alpha to form a chip end for forming an acute angle, but the pressing face 4 of the jig 2 to be used is formed to be parallel to the side face 5 of the chip 1. Thus, when the chip 1 is pressed by the jig 2, the pressing face 4 of the jig 2 is brought into contact with the side face 5 of the chip. Thus, a pressing load at the time of controlling the position is reduced to prevent the cutout of the end of the chip.
