Abstract: A sensor unit includes: a sensor that is attached to a measurement target object becoming deformed in response to a swing taken with the measurement target object and that generates an output signal indicating a relationship between a physical quantity related to an amount of deformation of the measurement target object and a time; a feature value generation circuit that generates a feature value, the feature value being a parameter indicating a feature of the swing, on the basis of the output signal obtained by the sensor; and a communication unit that is attached to the measurement target object and that transmits the feature value to an external device by wireless communication or wired communication.

Abstract: A data processing apparatus includes an arithmetic circuit that performs an acquiring step of acquiring swing data indicating relationship between a physical quantity concerning an amount of deformation of an object to be measured and time, a determining step of determining whether the swing data indicates the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung, to determine whether the swing data is to be deleted, and a deleting step of deleting the swing data if it is determined that the swing data does not indicate the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung.

Abstract: A network-based server device for managing product inventory information on an individual-store basis, the server device including a receiving unit receiving requests for product information from a client device, and a processing unit transmitting, to the client device in response to the request for product information, product inventory information on an individual-store basis corresponding to stores selected on the basis of client or customer identification information.

Abstract: A safety circuit 31, which compulsorily closes an on-off valve for supplying a gas to a burner when a microcomputer for performing a combustion control is in an abnormal condition, does not operate unless abnormality occurs to the microcomputer 1, and therefore even when the safety circuit 31 is out of order, an ignition operation is performed as it is. A transistor 4 is not turned off until a fixed time elapses from a start of an ignition sequence in the safety circuit 31, but the fixed time is shortened by a timer acceleration circuit 32, and if the transistor 4 is turned off by a transistor 2 being turned on, the safety circuit 31 is determined as normal, so that the normal ignition sequence is executed thereafter.

Abstract: An inventive oil pump system in a power train has a simple oil-delivery arrangement employing a hollow torque-input member containing a member to which oil is to be delivered, a drive shaft extending from the interior of the torque-input member and capable of being rotated by the torque-input member, an oil pump disposed coaxially with the drive shaft, a sleeve fixed to the oil pump and coaxially surrounding the drive shaft, a hollow pump-drive shaft coaxially surrounding the drive shaft, being journalled within the sleeve thus forming an oil-discharge passageway surrounding the drive shaft, and a coupling comprising a non-circular opening in the torque-input member and one end of the pump-drive shaft being inserted into the opening, the end of the pump-drive shaft having a non-circular cross-section capable of engaging the walls of the opening while leaving some radial clearance between part of the walls of the opening and the outer surface of the end of the pump-drive shaft.

Abstract: A clutch disc has at least two kinds of torsion damper springs arranged circumferentially around a hub of the clutch disc. First damper springs have a spring constant smaller than that of second damper springs. The first springs and the second springs are not arranged in series, end to end, in a circle, but the first springs are arranged in parallel with the second springs. The first springs are wound around an annular wire guide concentric with the hub. In one embodiment, the annular wire guide extends through the second springs, and the first springs are inserted in the second springs, respectively. In another embodiment, the annular wire guide is mounted on the outer periphery of a flange of the hub outside the second springs.

Abstract: A common housing is used for a torque converter or clutch and a center brake device. The drive shaft of the torque converter or clutch is connected to the input shaft of a transmission, which is housed in a housing adjacent to the common housing. The output shaft of the transmission lies parallel to the input shaft and the clutch drive shaft and extends into the common housing. The center brake device is fixed to the free end of the transmission output shaft and within the space defined by the converter or clutch housing. To minimize housing dimensions, the center brake device and the clutch or torque converter share the space defined by the converter or clutch housing. To better ventilate and cool the clutch or torque converter, the common space may open directly to atmosphere through an opening in the housing.

Abstract: A synchronizer ring for a synchromesh device for use in a transmission comprises an annular body of a wear-resistant metal forming a conical slide surface, and a main ring body made of a resin molded integrally on the annular body. The synchronizer ring according to the invention is light weight and economical of manufacture and can perform smooth contacts at chamfered surfaces and operate without producing any noise.

Abstract: The present invention relates to an automotive transmission for an industrial vehicle. The main shaft of the transmission gear is hollow and internally splined to be slidable along and synchronously rotatable with an externally splined input shaft. Upon removal of a snap ring which holds at least two gears and a synchronizer (disposed between the gears) in place on the main shaft and the removal of a lock pin which interconnects the main shaft and the input shaft, the main shaft can be slid toward the clutch allowing the gears and synchronizer to be slipped, one by one, off the end of the main shaft and readily replaced with new units.
