Title: Developing device
Inventor: ARAO KOUZOU
IPC: G03G15/09
Filed: 1979-03-05
Abstract: PURPOSE: To make image reproducibility good, faithfullness high and achieve the longer service life of developer by providing a magnetic field generating means on the inner side of a holding means of the upper stream image in the developer moving direction of the developer holding means surface than the developer removing means.  
     CONSTITUTION: When the developer is removed by a developr removing plate 6, the sleeve 2 surface is maintained always clean and this is good for development performance but since it is removed mechanically, the cohered toner is produced. To prevent the production of this cohered toner, a magetic pole 3e is newly disposed in the fore-process position of the removing plate 6 in contact with the sleeve 2. This causes the toner having returned into a hopper 5 without contributing to development to be trapped by the magnetic pole 3e and prevents the same from colliding against the removing plate 6 by large momentum. Thereby, the occurrence of cohesion and fusion is obviated despite the use of mechanical scraping means, thus the even toner layer may be obtained and good images obtained.

IPC: F01D17/16
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of damage caused by the vibration of a moving blade by attaching a variable nozzle fixed to a gas entrance flow passage for the rotary-driven moving blade to a nozzle rotary shaft such that its rotational center is positioned in an exit rear end side rather than the particular position of a nozzle from the exit rear end with respect to a nozzle cord length. SOLUTION: A variable nozzle 2 provided in a variable displacement type exhaust turbine supercharger is fixed in the end part of a nozzle rotary shaft and rotated integrally with the nozzle rotary shaft by the operation of a nozzle driving part to change the entrance angle and the passage area of gas. In this case, the nozzle rotary shaft is attached to the variable nozzle 2 such that the rotational center 14a of the variable nozzle 2 is set to the distance L1 -<=1/3L (L is a nozzle cord length) of the variable nozzle 2 from a nozzle exit rear end 4.  Thus, when the nozzle rotary shaft and the variable nozzle 2 are rotated, the changing amount of the distance of a nozzle rear end distance ΔR is smallest, the changing amount of a ratio ΔR/WN between the nozzle rear end distance ΔR and a nozzle blade width WN is suppressed small and an increase in the exciting force of a moving blade 7 is limited.

IPC: H04J14/08
Filed: 1980-02-29
Abstract: PURPOSE:To obtain a pulse light output of a high repetitive frequency with a high peak powder, by securing a synchronous operation between a plural number of pulse oscillating lasers and deflectors and radiating the output light given from each laser in the same direction through the deflector. CONSTITUTION:The light source 1 consists of semiconductor lasers 1a-1c which can be driven independently and is then driven by the synchronous signal generator 4. The beams emitted from lasers 1a-1c are incident to the acoustic-optical deflecting element 3 in different angles and via the lens 2. The deflecting angle of the element 3 is varied by the output signal of the generator 4 via the driver 5 and synchronously with the lasers 1a-1c. Thus the direction is set constant for the emitted beams. As a result, a pulse light output can be obtained with a high repetitive frequency and high peak power.
