摘要:
A table apparatus for a machine tool for moving a table along a guide member by a driving mechanism, feeding of the table being controlled by a feedback scale in cooperation with the driving mechanism, the feedback scale having a scale portion and a detecting portion, with opposed vicinal surfaces for accepting the feedback scale defined on the guide member and the table, respectively, the scale portion of the feedback scale being mounted on one of the surfaces, while the detecting portion is mounted on the other.
摘要:
A machine tool in which a feed member is fed in a feeding direction relative to a fixed member wherein the feed member is guided by a linear linkage mechanism including a first arm linked to the fixed member at its one end so as to swivel about a first axis, a second arm having the same length as the first arm and being linked to the first arm at its one end so as to swivel about a second axis and also linked to the feed member at its other end so as to swivel about a third axis. A first gear is secured on the fixed member at the one end of the first arm and is coaxial with the first axis. A second gear is secured on the second arm at the other end thereof and is coaxial with the second axis. A chain is provided around the first and the second gears. The first gear has a diameter twice that of the second gear.

A spindle device in which a coolant passage 26, capable of being selectively connected to a main passage 17, is provided at downstream of the main passage 17, an air passage 32, capable of being selectively connected to the main passage 17, is provided externally of the coolant passage 26, a first open-close means 20 is provided between the main passage 17 and the coolant passage 26, and a second open-close means 30 is provided between the main passage 17 and the air passage 32, whereby when the tool is clamped, the first open-close means 20 is opened to connect the main passage 17 with the coolant passage 26 and the second open-close means 30 is closed to cut-off the connection between the main passage 17 and the air passage 32 whereas when the tool is unclamped, the first open-close means 20 is closed to intercept the connection between the main passage 17 and the coolant passage 26 and the second open-close means 30 is opened to connect the main passage 17 with the air passage 32.
摘要:
A machine tool comprises: (a) a tool (22); (b) a body (2); (c) a tool supporting means (10) for supporting the tool (22) provided relative to the body (2); (d) a means (4) for supporting a pallet (P) for setting a work (W), the support means (36, 35) being provided relative to the body (2); (e) a first moving means (31, 32, 32a, 33, 34, 37, 39) for moving the means (4) about a center axis (U2) along a first direction (B1, B2); and (f) a second moving means (11, 12, 13, 14, 15, 16, 17, 18, 19, 20) for moving the tool supporting means (10) so as to cause relative motion between the tool supporting means (10) and the means (4) for performing machining operation of the work (W).
摘要:
A three-dimensional displacement gauge comprising a housing, a probe rotatably and slidably mounted on the housing, the probe is slidable along a first direction and having a contact member attached at one end thereof, two emitting members mounted on the probe each for emitting a light beam, two-dimensional measuring member such as a position sensor fixed to the housing for detecting the light beams, a biasing spring for biasing the probe toward the contact member, and a limit switch attached to the housing for detecting whether or not the probe moves in the first direction. The two-dimensional measuring member detects the light beams struck thereon so as to measure a small displacement of the contact member of the probe either in the first direction or in a second direction perpendicular to the first direction. In another mode, the two emitting members are mounted on the housing, and a mirror is mounted at the other end of the probe, and the two-dimensional measuring element detect the light beams struck thereon from the emitting members by way of the mirror.
摘要:
A key switch structure which enables a reduction in the width of the key switch. A key switch structure comprises a first support member (22), a second support member (23), and a third support member which are arranged independently of each other, the first support member (22) having rotation pins (22d, 22e) and slide pins (22a, 22b), the second support member (23) having rotation pins (23e, 23f) and a circular columnar slide section (23a), the third support member having front end sections (24d, 24e), which are slidably held, and a support shaft section (24a). A key top (21) is supported by the support members (22, 23, 24) so that the key top (21) can move in the vertical direction. The length of at least one side of each of the support members is set to be less than or equal to the mounting diameter of a rubber dome (27).

There is provided a keyboard structure capable of preventing a fingernail of a user from being inserted between key tops and achieving uniform illumination without illumination leakage. A key top body portion (120a) and an upper sheet (120b) are integrally formed to form a key top (120) and a flange portion (120d) is formed by protruding the upper sheet (120b) from the key top body portion (120a) toward an outer circumferential direction. A frame (122) is disposed between the adjacent key tops (120) and a gap is closed by the flange portion (120d) of the upper sheet (120b) and a flange portion (122a) of the frame (122).
摘要:
A semiconductor device is provided which has a semiconductor element having an element forming surface at which a sensor element is formed, a back surface on the opposite side of the element forming surface, and a light transmissive protective member laminated over the element forming surface via an adhering portion. The semiconductor device includes a region exposed from the protective member at the outer peripheral end portion of the semiconductor element, when viewed from the protecting member in a laminating direction.
摘要:
A method of manufacturing a semiconductor device and a semiconductor device including a first semiconductor element mounted on a first surface of a base plate, wherein solder balls are formed on a second opposite surface of the base plate—such that the second opposite surface includes an area without solder balls. At least one second semiconductor element is mounted to the base plate at the area of the second surface without solder balls. The at least one semiconductor element may be mounted to the base plate using low molecular adhesive, or in the alternative, high temperature solder.
