Title: Developing device
Inventor: NAKAI HITOSHI
IPC: G03G15/09
Filed: 1990-04-25
Abstract: PURPOSE:To simplify the structure by arranging a belt conveyor which conveys a developer toward the surface of a photosensitive body in a developing tank and arraying N and S poles of a magnet alternately on the back surface side of the belt conveyor in the conveying direction of the developer. CONSTITUTION:A magnet 23 which is fixed to a case 24 and a belt sleeve 22 which is rotatable around the magnet 23 are provided in the case 24, and toner 31 and carriers 32 are stored. The case is open at one end and the opening part faces the photosensitive drum 11. Then the N and S poles are magnetized alternately in the fixed magnet 23. Friction is therefore caused between the toner 31 and carriers 32, and toner 31 and belt sleeve 22 to charge the toner electrostatically to a specific electrostatic charging quantity. Consequently, a complicate driving mechanism which rotates the magnet roller is not necessary and the structure is simplified.

Title: Orthogonal polarization type light frequency shifter
Inventor: HORIUCHI SHIGENORI
IPC: G02F2/02
Filed: 1989-04-28
Abstract: PURPOSE:To obtain the orthogonal polarization type light frequency shifter which facilitates optical axis adjustment, etc., and obtains an extremely low beat signal by providing two light frequency shifter parts which differ in performance in an acoustooptic medium and providing them with mutually orthogonal planes of polarization, and obtaining two diffracted light beams which are slightly different in frequency. CONSTITUTION:When laser beam 7 is made incident on an ultrasonic wave front 8 at an angle thetaB, the 1st light frequency shifter 21 obtains the 1st diffracted light 9 and transmitted light 10 which propagates rectilinearly. This 1st diffracted light 9 is a P wave which has a frequency f0+fs shifting from the frequency f0 of the laser beam 7. Part of the transmitted light 10 of the 1st light frequency shift part 21 becomes the 2nd diffracted light 12 (S wave) and transmitted light 10 at the 2nd light frequency shift part 22. The frequency of the 2nd diffracted light 12 is f0+fl and the frequency of the beat signal obtained from the 1st and 2nd diffracted light beams 9 and 12 is the difference between f0+fl and f0+fs, i.e. the difference between fl and fs. Then fl and fs are both smaller than f0, so the difference between them is smaller. The beat signal of low frequency can, therefore, be obtained.

Filed: 1979-08-30
Abstract: PURPOSE: To enable tracing fusion cutting to be performed with high accuracy and efficiency by wide working capacities by securing a balance weight mechanism to the root end of the link mechanism provided with a tracing roller and a torch.  
     CONSTITUTION: The position of a weight 16 is set and fixed on a weight supporting arm 7 so as to offset the unbalance turning force by the gravity action around a pivot part 4 of a link mechanism A fixed with a tracing roller 14 and a torch. Thence, when the tracing roller 14 is rotatively driven, the tracing roller 14 surely rolls while being magnetically attracted along a tracing die 20 without receiving so much the downward deviating force owing to the gravity action. As a result, the torch applies fusion cutting to the work W to be treated with high accuracy and efficiency.
