摘要： PROBLEM TO BE SOLVED: To provide a method for forming a projecting shaft in an electronic storage device, the method that enables cracks or fractures less liable to occur in the projecting shaft which is formed integrally with a base and that enables the effective length of the projecting shaft to be expanded. SOLUTION: On the base of the electronic storage device, there is formed a projecting shaft whose distal end is plugged. The base 1 is placed on a die 4 formed with a hole 4a having a prescribed inner diameter, and is pressurized by a press tool 8 from one direction. This moves a portion of the base into the hole of the die, thereby integrally and projectingly forming the projecting shaft. In the hole 4a of the die 4, a compressing member 5 is arranged that presses the base in the direction opposite from the pressurizing direction of the press tool 8, and the compressing member compresses the distal end of the projecting shaft 2 to be formed by the press tool 8.

摘要： PROBLEM TO BE SOLVED: To provide a forging punch, forging equipment, a micro forging method, a liquid jetting head manufacturing method which realize accurate formation of a partition of a recessed part and highly accurate working of a recessed shape for a pressure generating chamber and the like, and also to provide a liquid jetting head or the like obtained by the liquid jetting head manufacturing method. SOLUTION: The forging punch consists of a first and second dies 51a, 52a for forging metallic base stock plates 30, 55. In the first die 51a, there are installed projections 53 arrayed in parallel and voids 53b formed between the projections 53. In the second die 52a, recesses 54a are provided so that the height of the middle section is set low. By working using the punch, the base stock plates 30, 55 on both sides of the recess 54a are moved to the recess 54a, with the flow rate of the base stock plates to the voids 53b uniformized as much as possible. Consequently, the liquid jetting head 1 is given stability in its liquid jetting characteristic, enabling the manufacturing cost to be reduced through the simplification of working by forging.

摘要： PROBLEM TO BE SOLVED: To obtain a high-quality bearing of good controllability with a simple machining in a short time, smooth in movement and with a low vibration, a low noise, and high rotation accuracy by inserting a mandrel having a desired groove shape on its peripheral face in the inside of the bearing, drawing the outside diameter of the bearing, and forming a convex or concave groove for generation of a dynamic pressure on the inside diameter surface of the bearing. SOLUTION: A mandrel equipped with a groove of desired shape on its outer periphery is inserted in the inside diameter of a metal bearing 10 of a circuit board 1 which also serves as the base for an outer rotor type brushless DC motor for a CD-ROM, and the metal bearing 10 is inserted in a housing 7, for drawing the outside diameter of the metal bearing 10, so as to form a convex herring bone groove for generation of a dynamic pressure on the inner face of the metal bearing 10. When it is assumed that the outside diameter of the bearing is D, the inside diameter of the bearing is d, the inside diameter of the drawing jig is A, and the diameter of the mandrel is B, it is preferable to satisfy (D-A)/D=0.005-0.035 and (d-B)/d A and d>B.

摘要： PROBLEM TO BE SOLVED: To reduce the number of part items, by integrally molding the support pin with forging work, cylindrically in a rear end face of a flange part, and by engravingly forming a recessed part, having an internal diameter larger than an external diameter of the support pin, coaxially thereto in the front end face of the flange part. SOLUTION: A plurality of recessed parts 21 are engraved by an equal angular pitch on the same circumference in a front end face of a flange part 20 integrally molded with an output rotary shaft 11, and a support pin 22 is protrusively provided cylindrically coaxially to the recessed part 21 in a rear end face of the flange part 20. The output rotary shaft 11 is supported by a sleeve bearing 12 fitted to the internal circumference of a flange 4b of an internal gear 4, and an armature rotary shaft 2 is supported by a sleeve bearing 13 fitted to the recessed part in a rear part internal circumference surface of the output rotary shaft 11. A plurality of planetary gears 7 are supported by each support pin 22 so that the planetary gear, through a bearing fitted to its internal circumference, is mashed with a sun gear 6 formed in a front end side of the internal gear 4 and the armature rotary shaft 2.
