  • Patent number: 7681830
    Abstract: A film feeding device etc. in which, even if film rolls in which tapes are applied to joint between films of the rolls are used, an occurrence of a bag making failure caused by the tape is prevented. A film feeding mechanism (10A) has a receiving member (72) for holding the leading edge of a film (1B) of the standby side and a joining sealer (71) for joining films (1A, 1B). A tape (B) applied to the film (1A) on the use side is detected by a sensor (83), and according to the result of the detection, a cutter (81) cuts of the film (1A) at a portion on the downstream side of the tape. Then, the cut film (1A) and the film (1B) of the standby side are joined by the joining sealer (71), and the two films joined are sent as a long film.

  • Patent number: 7640812
    Abstract: A cap is provided on a diaphragm, and a first end of a flexible board is connected to the cap. A cover is attached to the cap. The cover directs a second end of the flexible board in a direction away from the diaphragm held by a joint so that the flexible board is supported while being curved. Since the flexible board is not locally bent at an acute angle, a crack is not generated on a copper pattern provided on the flexible board.

  • Publication number: 20070089523
    Abstract: An adapter (2) disposed between joint (1) and diaphragm (3) includes an axis portion (21) and a flange (22) projecting radially from the axis portion (21). The axis portion (21) is arranged so that one end thereof does not interfere with the joint (1) and the other end is welded to the diaphragm (3), and the joint (1) is caulked to a peripheral edge of the flange (22). Since the diaphragm (3) is not directly joined to the joint (1), welding is not performed near the joint (1), but can be performed in a wide space where equipment is suitably arranged. In addition, caulking operation of the joint (1) to the adapter (2) can be performed by pressing a caulking portion (12C) formed in advance in the joint (1) against the outer peripheral edge of the flange (22), so that a wide space is unnecessary for caulking.

  • Patent number: 7150198
    Abstract: A pressure sensor (1) includes a diaphragm (21) with a bottom formed of a thin-wall portion (210) and a pressure introducing joint (10), in which an austenitic precipitation hardening Fe—Ni heat resisting steel having high mechanical strength is used for the diaphragm (21), while an austenitic stainless steel that is relatively inexpensive is used for the pressure introducing joint (10). The diaphragm (21) and the pressure introducing joint (10) are integrated by welding, and Ni content of a weld portion is appropriately adjusted. Thereby, the pressure sensor (1) achieves high accuracy and reliability, and usage amount of the expensive austenitic precipitation hardening Fe—Ni heat resisting steel can be minimized in manufacturing the pressure sensor (1). Also, since the austenitic stainless steel has an excellent corrosion resistance, the pressure sensor (1) can be used in measurement of a fluid with high corrosiveness.

  • Patent number: 6859823
    Abstract: A workflow server is provided with, in association with a user management table 100 for managing work items for each user, a list 130 of substitute users for indicating a substitute user for each work or process and a list 140 of users in charge who designates the user as a substitute. When a client terminal user selects a specific user among the users in charge on the list 130, the workflow server checks the power of substitute by referring to the list 140 of substitute users for the selected user, thereby to allow the client terminal user to process a predesignated unprocessed work item instead of the selected user in charge.

  • Patent number: 6474170
    Abstract: A pipe having a through-hole of smaller diameter than a pressure port is disposed in the pressure port. Therefore, a volume of the pressure port can be reduced by the thickness of the pipe, thereby improving response of a pressure sensor. Furthermore, there is no need for the pressure port having smaller diameter to be provided by drill processing, so that a volume in the pressure port can be easily adjusted. Accordingly, the volume in the pressure port can be reduced with a simple structure to improve response of the pressure sensor.

  • Patent number: 6298730
    Abstract: A pressure sensor (1) having a first terminal (35), the first terminal (35) including a horizontal portion (61) and a vertical portion (62) at an intermediate portion thereof and being elastically deformable. A portion of the first terminal (35) being inserted and soldered to a circuit substrate (33) has a collar portion (63) being abutted around a through-hole (51) of the circuit substrate (33). The first terminal (35) is fixed at a state being pressed to the circuit substrate (33) by the collar portion (63) and being slightly compressed between a base member (32). When the circuit substrate (33) and the base member (32) are spaced apart by circumambient heat, the first terminal (35) can follow by the compressed margin. When the first terminal (35) itself is thermally expanded, the first terminal (35) can follow by an elastic deformation of the horizontal portion (61) and the vertical portion (62).
