Abstract:
PROBLEM TO BE SOLVED: To efficiently improve the productivity of an optical member molding mold (structure) when the mold (divided mold 19) for molding an optical member such as a Fresnel lens is manufactured by machining a mold material (workpiece material) 2 by means of a cutting tool 4 of a quadruple spindle lathe type machining device 1 provided with an X axis, a Y axis, a Z axis and a C rotation axis. SOLUTION: There is provided an optical member molding mold (structure) machining method which is implemented in the following manner. Firstly, the mold material 2 is mounted on a mold material mounting portion 7 in the machining device 1, and the mold material 2 is rotated about the C axis as a rotation center 8, followed by driving the cutting tool 4 for moving in the X axis direction and the Y axis direction. Next the mold material 2 is cut by the cutting tool 4 at a required cutting speed relatively generated at a required location 20 of the mold material 2, and elliptically vibrated and machined by the cutting tool 4, to thereby form a cavity recess 17 for molding the Flesnel lens formed with an opening of a required shape and a machined surface (e.g. a concave surface) of a required shape.

Abstract:
PROBLEM TO BE SOLVED: To provide a resin sealing mold for an electronic component which makes various resin materials (including a strong adhesion sealing material) satisfy both mold release properties and corrosion resistance of the mold and form the surface treatment layer of the mold enough in consideration of environmental problems. SOLUTION: By forming a chromium carbide film A (surface treatment layer) in a necessary place of each of the surfaces of these molds 1 and 2 by depositing (surface treatment) by a vacuum film depositing method, the resin sealing molding of the electronic component 5 set on a substrate 6 can be carried out in mold cavities 3 and 4.

Abstract:
PROBLEM TO BE SOLVED: To provide a resin sealing molding apparatus for an electric component which can mainly improve the strength of a component single body and quality in accuracy in a press structure, and align the pressing center position of the press structure with the center position of a mold. SOLUTION: A hold frame (press frame) mechanism 55 of this apparatus 100 is provided so as to be reciprocated along a machine table frame 72 by a proper reciprocation driving mechanism 78. In an example shown in a figure, a pressing center position 79 in a hold frame (press frame) 77 and a pressing means 73 can move in the same direction (in this case, left direction) as the moving direction of the mechanism 78, and can be aligned with a center position 80 of a mold 51 in a mold region P including the mold 51 arranged between mounting blocks 68 and 71 and a mold opening/closing mechanism 54.

Abstract:
PROBLEM TO BE SOLVED: To prevent formation of resin burrs on the front surface of substrate by simplifying total structure of die to form a resin seal of electronic component loaded on the substrate, and by absorbing fluctuation in thickness of substrate at the time of forming the resin seal of electronic component. SOLUTION: The resin seal forming apparatus is constituted by forming a die 110 to form resin seal of electronic component from a first die 111 and a second die 112, and by laminating and allocating, to the die contact surface P, L of both dies, a die structure unit (die 110) of a plurality of units in which a substrate supplying part (substrate supplying set surface 113) is provided for supplying a single sheet of preliminary substrate 400 loading electronic component. Moreover, a die closing mechanism (press frame mechanism 130) is also arranged to simultaneously apply the die tightening pressure to the laminated by arranged die structure unit (die 110).

Abstract:
PROBLEM TO BE SOLVED: To prevent the formation of resin burrs on a substrate surface by simplifying the entire structure of a mold 110 used for resin-sealing molding an electronic component mounted on a substrate 400 and absorbing variations of the thickness of the substrate 400 in resin sealing molding the electronic component. SOLUTION: The mold 110 used for resin sealing molding the electronic component is composed of a first mold 111 and a second mold 112, and planar substrate feed setting surfaces 113 having no step are formed on mold matching surfaces (P.L surfaces) of both the molds. Also, a pot block 140 is arranged on the side surface 110a of the mold 110 matching the mold matching surfaces (P.L surfaces) of both the molds so as to be freely joined and separated, and the mold matching surfaces are joined to the pot block 140 and a molten resin material in the pot block 140 is directly injected into a cavity 114.

Abstract:
PROBLEM TO BE SOLVED: To dispense with replacement of a fixing base to fix a subject, and prevent abrasion of the fixing base in cutting the subject along mutually crossing cutting lines. SOLUTION: This cutting device is for cutting a subject 28 along the mutually crossing cutting lines 63 and 64 by injecting water including abrasive grains under high pressure. It is provided with the fixing base 66 for fixing the subject 28, groove parts 68X and 68Y provided at positions corresponding to and below the cutting lines 63 and 64 in the fixing base 66, projected parts 67 provided to get in contact with the subject 28 at other parts than the groove parts 68X and 68Y on the fixing base 66, base parts 69 provided to connect the projected parts 67 to each other almost in parallel to the cutting lines 64 extended in the Y-direction at the groove parts 68X and 68Y, a frame part 70 provided to connect the base parts 69 to each other at least in part of the outer circumference of the fixing base 67, and protective members 74 detachably provided to cover the base parts 69.
