Title: Epithelium cell strain of human crystalline lens
Inventor: IBARAKI NOBUHIRO
IPC: C12N5/10
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain the subject cell strain free from the trouble of inducing viral infection in transplantation and useful e.g. for the treatment of crystalline lens diseases such as cataract by imparting epithelium cell of crystalline lens with an infinite proliferation potency in vitro by a specific method without using the infection with live virus. SOLUTION: This cell strain is a monoclonal epithelium cell strain of human crystalline lens (SRA01/04 strain, etc.) having uniform property, capable of expressing an extrinsic immortalizing gene and established without using the infection with live virus e.g. by the transfection of an epithelium cell of human crystalline lens originated from epithelium of crystalline lens by a plasmid expression vector functionally integrated with an immortalizing gene. A heat- sensitive epithelium cell strain of human crystalline lens (SRA01/01 strain, etc.) terminating the proliferation within about 2 weeks at about >=36 deg.C and capable of stably continuing the proliferation at about 33 deg.C can be produced by transfecting with an expression vector containing an immortalizing gene expression cassette exhibiting temperature-sensitive expression behavior.

IPC: G02B6/40
Filed: 1981-07-31
Abstract: PURPOSE:To reduce the loss of connection of optical fiber connecting parts by previously forming unrestored distortion with a prescribed length on the end parts of optical fibers. CONSTITUTION:Unrestored distortion is formed on the end parts of optical fibers, an Ni/Co arroy layer with even thickness is formed on the periphery of each optical fiber 2, 2' to suck the leading ends of terminals 2a, 2a' of the optical fibers into a matching streaky groove 4 by a permanent magnet and bending work is applied so that an optical axis is made approximately parallel with the streaky groove 4 under the condition that the terminal 2a' is sucked on the matching streaky groove 4. Since the optical fiber terminals 2a, 2a' are distorted by metallic films 1, 1', angle divergence is not generated on the optical axises of both the optical fibers when both the end surfaces of optical fiber terminals 2a, 2a' are made butt with each other on the matching streaky groove 4. Consequently the loss of connection of optical fiber connecting parts can be reduced.

IPC: A01B33/12
Filed: 1987-05-15
Abstract: PURPOSE:To achieve tilling of soil in high accuracy, by detachably attaching a wall-forming member between a rotary and a rotary cover acting also as a tilling depth sensor. CONSTITUTION:The oscillation angle of a rear cover 6 of a rotary is detected by a potentiometer 11 and the depth of tilling is controlled based on the detected angle.

Title: Digital etching process of iii-v compound semiconductor
Inventor: KIKUTA KUNIKO
IPC: H01L21/302
Filed: 1988-05-16
Abstract: PURPOSE:To enable a GaAs substrate to be digital-etched by a method wherein halogen gas radical is chemical-adsorbed on the semiconductor surface by one layer only at low temperature and then the temperature of semiconductor is raised to etch the atomic layers one by one from the semiconductor surface. CONSTITUTION:A GaAs substrate fed to an ultrahigh vacuum chamber with substrate temperature kept at 300 deg.C is irradiated with hydrogen radical beams for 15 minutes. A thin natural oxide film formed on the substrate surface is perfectly removed by the hydrogen radical beam irradiation. First, the GaAs substrate in the chamber with the substrate temperature kept at -40 deg.C is irradiated with chlorine radical beams for 30 seconds. At this time, chlorine 3 chemical-adsorbes by one layer only to dangling bond of Ga as the uppermost layer of the GaAs substrate. Secondly, when the chlorine is cut off and the substrate temperature is raised up to 50 deg.C, the chlorine 3 becomes chlorides of Ga 1 and As 2 one layer below the Ga 1 to be removed. Furthermore, the GaAs substrate can be etched away by two atomic layers by repeating the processes of irradiating the GaAs substrates kept at the temperature of -40 deg.C with chlorine radical and then raising the temperature up to 50 deg.C.

Title: Constant torque mechanism
Inventor: TAKITA MASAAKI
IPC: B65H18/06
Filed: 1985-06-03
Abstract: PURPOSE:To rotate a shaft with constant torque by driving first and third circular parts pressed against each other with a spring having variable spring pressure under the condition that tooth form mating surfaces of second and third circular parts fitted onto the shaft are formed in a portion with a gap. CONSTITUTION:When a part 1 is rotatably driven by a motor or the like, pressure change occurs in inclined portions of tooth form surfaces 14, 17 of respective contact surfaces of parts 2, 3. Here, a force to drive an ink film mounted on a paper pipe 8 with a part 3 acts to reduce a frictional force between the part 2 and a frictional plate 4 so that slippage occurs to prevent the transfer of film when said force exceeds the frictional force. When said force does not exceed the frictional force, the film is transferred with constant set torque. A coil spring 6 between parts 2, 3 works also as a drive transmitting element in the rotational direction.
