IPC: G03G9/087
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent image defects due to flocculation of a toner from being generated by adding a process to deflocculate the flocculated material produced in a dry powder toner. SOLUTION: Resin particles produced by a polymn. method are cleaned to remove a hydrophilic material. The polymer particles are subjected to a solid-liquid separation process to deflocculate a flocculated material and to obtain a dry powder toner. Namely, polymer particles flocculated and dried are deflocculated into particles of the original polymer particle unit, so that problems caused by flocculated particles can be prevented. For example, mechanical shock which does not break the polymer particle itself is added to the dry flocculated polymer particles to obtain individual particles. Namely, the process is carried out by mixing and stirring in a drying and mixing machine. For example, efficient pulverization can be performed while preventing breaking of the polymer particles by using a Henschel mixer at 15 to 50m/sec rotation rate of vanes.

Abstract: PURPOSE:To prevent strain and distortion by fitting the opening of a battery container formed by drawing austenite stainless steel to a tool having a recess fitting to the opening, then applying heat treatment to the container to remove residual stress. CONSTITUTION:The opening of a battery container 11 formed by drawing of austenite stainless steel is fitted to a tool 12 having a recess 12a fitting to the opening and a through hole 12b useful for heating the container 11. The container 11 fitted to the tool is heated in a heat treatment furnace at reduced pressure or in an atmosphere of hydrogen at about 1,050 deg.C. Part of the container is transformed form austenite structure to martensite structure by drawing. This structure transformation results in work hardening and residual stress and causes the container to develop aging hardening crack or stress corrosion crack. Returning the martensite structure to austenite one by heat treatment prevents the container form these problems. By this treatment, the strain and distortion in the battery container 11 are removed, and complete circle of the opening is maintained. Thereby, a battery cover is smoothly fixed to the container to obtain a sealed type battery.

Filed: 1978-06-22
Abstract: PURPOSE: To make it possible to switch stably the running direction of a high-speed running tape by rotating always two capstans in opposite directions previously and opening and closing two pinch rollers.  
     CONSTITUTION: Capstans 23 and 23' are always rotated in opposite directions previously, and the rotation of capstan 23 with which pinch roller 22 driving a tape is brought into contact is transferred to pulley 25 through belt 24. Lever 34 supporting linkage plate 27 which fixes the bearing of pulley 25 is moved to compress belt 24 to small pulley 31, thereby transferring the rotation of pulley 25. Consequently, the reel is rotated by the frictional force dependently upon the rotation of the small pulley and winds up the tape. Next, when a tape end mark is detected, plunger 37 is released to sepsrate pinch roller 22, and plunger 37' is operated to cause belt 34 to compress belt 24' to small pulley 31', and pinch roller 22' is brought into contact with capstan 23' again. Thus, the tape running direction can be inverted.
