Title: Ratchet device
Inventor: TANABE SHIGERU
IPC: B65H18/08
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent an unexpected engaging release by constituting an operating means by a ratchet lever connected to a ratchet tooth, and a release lever for displacing the ratchet lever into a position which is enabled an operation and a position which is not enabled the operation. SOLUTION: A release lever 11 is pushed downward opposing to a spring 12 so as to engage a claw part 15 and a claw receiving part 16 with each other, the release lever 11 is inclined in clockwise direction in a condition in which the most upper end of a long hole 14 is brought into contact with a pivotally supporting pin 8, and thereby, the ratchet lever 9 is rotated together. As a result, engagement of the ratchet wheel 7 and a ratchet tooth 10 is released. In the case where the release lever 11 is inclined without pushing down, the claw part 15 and the claw receiving part 16 are not engaged with each other, only the release lever 11 is inclined in a condition in which the lowest end of the long hole 14 is brought in contact with the pivotally supporting pin 8, and thereby, engagement of the ratchet wheel 7 and the ratchet tooth 10 is not released.  If the top end of the release lever 11 is caught on the branch of a tree and the like and it is inclined, the ratchet lever 9 is not inclined so as to prevent an engaging band 5 from loosening on running of a vehicle.

Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To surely take out a recording material, especially a paper sheet, stackedly stored in a cassette, etc., from the uppermost part one by one by freely swinging a downstream side shaft of a driven shaft in the direction advancing to/separating from the recording material and providing a member which abuts on the top face of a belt and makes it tension, when the driven shaft is swingingly separated from the recording material. SOLUTION: When a drive shaft 103 is driven by rotation of a motor M and a pulley 105 is rotated, the top side of a belt B is tensioned, the bottom side of the belt forms a loop, and a recording material on the uppermost part is taken out. When the top side of the belt B is sufficiently tensioned, the drive force by the pulley 105 is transmitted to a pulley 102 so that a driven shaft 100 starts to rotate.  When the taken-out recording material is advanced so as to become such a state as receiving the carrier force of a pair of register rollers, the driven shaft 100 is rotationally moved in the direction separating from the recording material by energizing force of a solenoid 113, the top side part of the belt B abuts on a suppression shaft 114, the belt B is set to a tensioned state, and the drive force of the motor M is cut off so that the recording material is made to advance by a pair of the register rollers.

Title: Manufacturing luminous tube for high pressure alkali metal vapour discharge lamp
Inventor: OOTANI KATSUYA
IPC: H01J61/36
Filed: 1978-08-29
Abstract: PURPOSE:To provide a durable discharge lamp of high transmittance by preventing cracking of ceramic tube sealing part by grinding both ends of a light transmittable alumina ceramic tube made of alumina particles of a specific size by abrasive particles of a specific size. CONSTITUTION:A luminous tube is prepared by grinding the internal and/or external surface of both ends of a light transmittable alumina ceramic tube 2 made of alumina particles of mean diameter over 80mu by abrasive particles of diameters less than 70mu. For example, the internal surface of both ends of an alumina ceramic tube 2 which is prepared from alumina particles of a larger mean particle size and thus provided with improved transmittance is ground by conical grinding face 13 of a grinding tool 12 having diamond grinding particles smaller than 70mu to form ground face 14, thus cracks and microcracks produced in cutting the tube are removed so that faulty sealing due to cracks is prevented providing durable discharge tube of a high transmittance.

Title: Synchronizing operation controller of rotor
Inventor: SATOU YOSHIKI
IPC: H02P5/52
Filed: 1984-05-24
Abstract: PURPOSE:To operate master and slave rotors at the same speed or at the prescribed speed ratio without mechanical coupling by applying the rotating difference of the two rotors to the rotating speed of the master rotor to control the slave rotor. CONSTITUTION:The output of a pulse generator 2 of a main rotor 1 is applied through an F/V converter 7 and an adder 8 to a controller 5 to control a slave rotor 3. A deviation counter 9, when receiving a pulse generated from the generator 2 and a pulse generated from a pulse generator 4, applies the difference to a D/A converter 10, which converts it to a voltage corresponding to the difference of the number of the pulses and applies it to the adder 8. Thus, the slave rotor is always rotated at the same speed as the master rotor or at the same rotary angle as the master rotor, and stopped at the same angle in case of stopping.

Abstract: PURPOSE:To automatically adjust sensitivity of control interlocking by equalized pressure applied to a wheel tract eliminating member depending upon hardness of soil surface, by controlling a front sensor and the wheel tract eliminating member in an interlocking way. CONSTITUTION:A valve arm 22 of a rise and fall control valve 21 of a fluctuating cylinder is interlocked to a link 9 of a float sensor 4 at a side corresponding to the arm and to a wire 23 of a wheel tract eliminating member 3. These parts, the float sensor 4 and the wheel tract eliminating member 3 are constituted in an interlocking way so that rise and fall of traveling wheels are controlled by changing the rise and fall control valve 21 while detecting change of soil condition. When the surface of soil is hard, the wheel tract eliminating member 3 is slightly dropped and stands at a high position a. A spring 24 is stretched strong and change resisting force of the rise and fall control valve 21 by the float sensor 4 is enlarged. When the surface of soil is soft, the wheel tract eliminating member is readily dropped and stand at a relatively low position b. The spring 24 is weakened and change resisting force of the rise and fall control valve 21 is lessened.

Abstract: PURPOSE:To obtain 3-oxo-5beta-steroid-DELTA<4>-dehydrogenase (3-OSD) having high purity on an industrial scale, by adding a specific immobilized material to a solution containing 3-OSD, thereby allowing the immobilized material to adsorb 3-OSD. CONSTITUTION:A 3-oxosteroid compound is subjected to peptide reaction with a ligand immobilization compound (e.g. AH-sepharose 4B) to obtain an immobilized ligand. The immobilized product is suspended in a buffer solution of 6-9pH and filled in a column. A 3-OSD solution produced by dissolving 3-OSD in a buffer solution having an electrical conductivity of <=20mmho/cm is flowed down through the column to effect the adsorption of 3-OSD to the immobilized ligand. The above buffer solution is passed through the column at an amount corresponding to about 3 times the volume of the column to elute impurities. After the above treatment, a concentrated salt buffer solution such as phosphoric acid buffer solution containing 0.1-0.5M of NaCl, etc., and having an electrical conductivity of >=40mmho/cm and 6-9pH is passed through the column to elute the enzyme. 3-OSD produced by this process has a purification ratio of as high as 25-50 based on the crude raw material.
