Title: Cutting device of barrel cam
Inventor: KATOU HEIZABUROU
IPC: B23C3/08
Filed: 1981-08-18
Abstract: PURPOSE:To process all types of barrel cams with a high precision without requiring the manual finishing by connecting a rotary table shaft and a rotary shaft of the object under process to a two shaft simultaneous control servo mechanism which controls the revolution. CONSTITUTION:In a cutting device of a barrel cam largely used for a high speed automatic machine, if the relationship between the barrel cam revolution angle and the turret revolution angle is substituted for the relationship between the revolution angle theta of a cam substance V and the revolution displacement S of a rotary table T, the locus N becomes equal to the shape of the cam groove of the barrel cam. Therefore, by arranging a rotary tool E such as a milling cutter with the same shape as a trailing roller at a fixed point, a cam groove with the desired shape can be obtained. The shaft of the table T and the rotary shaft of the object under process are connected to a two shaft simultaneous control servo mechanism, which controls them so as to satisfy S=f(theta). Accordingly, all types of barrel cams can be processed with a high precision.

IPC: G03G15/16
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To restrain the deterioration of image quality to be caused by forming a high-density image or using liquid developer of non-Newtonian fluid by constituting the process so that a secondary transfer stage for secondarily transferring a transfer image is executed for a longer time than a primary transfer stage for primarily transferring a visible image. SOLUTION: A primary transfer roller 7 is desposed inside an intermediate transfer belt 6 and forms a primary transfer nip by putting the belt 6 between the drum 1 and the roller 7. Then, a secondary transfer roller 9 abuts on the part of the belt 6 positioned between rollers for laying 8b and 8c and forms a secondary transfer nip. The nip length of the secondary transfer nip is set to be longer than that of the primary transfer nip. Namely, the secondary transfer stage is executed longer than the primary transfer stage in this printer. Thus, the time to electrophorese a primary transfer image from the belt 6 to recording paper 15 is secured to be long, and the electrophoretic efficiency of the primary transfer image in the secondary transfer nip is improved.

Title: Solenoid valve
Inventor: MURAKAMI FUMIYOSHI
IPC: F16K31/06
Filed: 1994-05-18
Abstract: PURPOSE:To relax flow rate characteristics during a high negative pressure and to perform high-precise control of a low flow rate by a method wherein when energization of an electromangetic solenoid is released, a main valve body is brought into seat to a valve seat to disconnect a fluid passage and the pressure difference of a communication hole in a partition wall is cancelled. CONSTITUTION:When an electromagnetic solenoid 1 is energized and the suction force thereof exceeds the energization force of a coil spring 7, a moving body 6 is attracted to the fixed core 5 side. Thereby, the bed seat 8a of a valve body 8 is separated away from a valve seat 34 and a communication hole 33 is released and inner holes 17a and 17b intercommunicate to allow fluid passages 13a and 16 to intercommunicate. In this case, a differential pressure is generated by the throttle opening 22 of an auxiliary valve body 21 between fluid passages 13a and 17 communicating with ports 11b and 11a, respectively. As a result, the auxiliary valve body 21 is energized to the valve seat 18 side. Thus, in a case a high negative pressure wherein the differential pressure exceeds the energization of a coil spring 26, the auxiliary valve body 21 is continued to seat a valve seat 18 and the area of an opening 15 is reduced to the area of the throttle opening 22 and a flow rate is decreased.
