Title: Joining method for different kind of metal
Inventor: OGASAWARA SHINOBU
IPC: B23K101/14
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a more inexpensive joining method by which the direct joining of a mating material to a piping structure is possible, joining reliability such as strength, a tightness, etc., is high, the treatment of the end face of a joining tube is easy and tolerances in dimension are large in the joining of different kinds of metals such as copper, aluminum, etc. SOLUTION: In the combination of the different kinds of metals showing an eutectic solidification phenomenon at the time of alloying, joining is performed by a process making a copper tube 1 and an aluminum tube 2 adhere closely by rubbing the abutted surface of the two materials by rotating the copper tube 1 after shifting it in the peripheral direction while it is pressed and is brought into contact, a process making eutectic melting liquid generate by heating the aluminum tube 2 up to the vicinity of a low melting point held by the aluminum tube 2 under pressure welding and a process making the eutectic melting liquid solidify by cooling.  The joining with high reliability can be provided because an oxidized film on the surface of a metal, which is the obstacle of the joining by friction caused by rotating and sliding, can be easily ejected and making the active surfaces of the metals adhere closely is possible. Even such a time when some deformations are generated in a pre-stage by using a soft metal, the shape of the end face of a joining part can be learned by a mating material by revolving, and a high productivity can be realized such as the extent of the allowable ranges of joining dimensions, the improvement of a yield, etc.

Title: Developing device
Inventor: TANAKA MASARU
IPC: G03G15/08
Filed: 1989-03-20
Abstract: PURPOSE:To prevent the solidification, etc., of developer and to secure stable development for a long period by turning an endless sheet member which segments the inside of a developer container into plural rooms and supplying the developer to the room on a developing sleeve side through a replenishment hole. CONSTITUTION:Throw-in opening parts 32a are respectively formed on the endless sheet members which segment the inside of a toner housing part 22 into the plural rooms 30A-30D corresponding to the size of the throw-in hole 22a of the toner housing part 22. By successively turning the endless sheet members by motors 34A-34C, toner T is supplied from the room 30A to the room 30D through the respective throw-in opening parts 32a. With such constitution, the toner T thrown from a throw-in hole 21a is housed in the endless sheet member at an upper stage through the throw-in opening part 32a. Since a comparatively small quantity of toner T is housed in the respective rooms 30A-30D, at such a timer, the weight of the toner T in the rooms 30A-30C is not exerted on the toner T in the room 30D and the solidification, etc., of the toner T is surely prevented even if the toner housing part 22 is a large capacity one.

Title: Voice coil
Inventor: HARA FUMIO
IPC: H04R9/04
Filed: 1983-04-22
Abstract: PURPOSE:To suppress an eddy current disturbing a current flowing to a voice coil by providing a slit to a metal-made bobbin part of the voice coil. CONSTITUTION:The slit 10 is provided to a part 1 of the bobbin 2 of the voice coil. Since the eddy current flows to the surface (side wound on the coil 1) of the bobbin 2, the slit 10 prevents the current from flowing. Since the eddy current is hardly produced even if a current flows to the coil 1, the current flowing to the coil 1 acts effectively so as to drive an objective lens 5 up to high frequencies. The width, length and number of the slit 10 is set properly depending on the size of the bobbin 2.
