摘要： In an acceleration sensor including a vibrator subject to a sliding vibration and a weight section connected to the vibrator and supported at a position different from the position of the center of gravity of an assembly of the vibrator and weight section, for detecting an angular moment about the support point, which is produced at the weight section by application of acceleration, as sliding vibration with the vibrator, the acceleration sensor includes a rectangular substrate having a plurality of electrodes electrically connected to the vibrator, a formation pattern of the plurality of electrodes is symmetrical about an axis parallel to at least one side of the substrate, and the plurality of electrodes have substantially equal thickness. Since the formation pattern of the electrodes on the substrate is symmetrical and the respective electrodes have substantially equal thickness, the vibrator that is bonded to this substrate does not incline and the detection sensitivity does not vary.

摘要： A wireless hub, connected to the USB bus of a computer, and a wireless port, connected to a USB interface of a peripheral device, are provided, and wireless communication is performed between the two. The wireless hub performs communication with the computer by converting a USB packet routed to a device into a wireless signal, and a wireless signal received from a device into a USB packet. The wireless port attached to each device also converts a wireless signal into a USB packet and vice versa. While it is normal for a plurality of wireless ports to be connected to a single wireless hub, an arrangement of one wireless hub and a corresponding single wireless port is also possible. A wireless hub and a wireless port each have a device identifier assigned to them, and in the USB-wireless conversion, a non-specific destination identified by a USB address and bus topology is converted into a device identifier. Inter-host communication is enabled by using the device identifier.

摘要： A process and apparatus is provided for automatically and continuously producing a mass of moldings. A continuous molding is manufactured by injecting a solid solution in order of precedence into a plurality of molds circulating in a line along an endless track and by solidifying the injected solution. The solution is preferably vinyl chloride resin or another synthetic resin. After the solution solidifies the mold is automatically removed from the molding. The continuous molding consists of a number of moldings open at the bottoms and connected end to end by a top plate, molded at the same time.

摘要： A small-sized, high detection sensitivity and high performance acceleration sensor having directional or non-directional sensitivity is disclosed. The acceleration sensor is provided with a vibrator having uni-directional polarization and a weight connected to the vibrator. The weight is supported at the position different from the center of gravity of the total body of the vibrator and the weight itself. The vibrator is disposed so that its direction of polarization axis is either consistent or inconsistent with an axis of the torsion of the vibrator.
