A power cut/connect device is proposed which is axially compact and is usable in a limited space. The device includes a first input member coupled to a power shaft, an output member mounted coaxially with the first input member, a first two-way clutch provided between the first input member and the output member, a second input member coaxially mounted with the output member, a second two-way clutch provided between the output member and the second input member so as to be disposed coaxially with and around the first two-way clutch, and a control unit for controlling the first and second two-way clutches for interruption and connection of power.

A friction type continuously variable transmission has double cones kept in contact with an input shaft and a drive cone and is capable of transmitting the rotation of the input shaft to an output shaft so that the output shaft rotates at a higher speed than the input shaft. A mechanism is provided for preventing the double cones from rotating about the input shaft and from coming off of their support shafts. A stay is mounted on a carrier supporting the double cones. The stay carries a guide roller bearing received in a guide fixed to a housing of the transmission. The stay thus prevents the rotation of the carrier while allowing only its axial movement. A stopper surface is provided at one end of the guide to restrict the axial movement of the carrier within a predetermined range.

Plating 5 having good slide friction characteristics is applied onto the pocket surfaces 4a1, 4a2, which are opposite each other in the circumferential direction of the pockets 4a of the carrier and onto the end face 4a3 in the axial direction. It is possible to improve the lubrication conditions at the contacting area of the outer circumferential surface of the planetary rollers and the pocket surface 4a1 of the carrier 4 by coating the plating 5 having good slide friction characteristics onto the pocket surfaces 4a1,4a2 of the pocket 4 of the carrier 4 and further onto the end face 4a3. That is, the friction force at the contacting area is able to be decreased by the plating 5 having good friction characteristics, whereby even in a case where the contacting area is lubricated with a little lubricant, thermal deterioration of the lubricant due to heat generation of the contacting area is suppressed and good lubrication actions can be expected.

A power transmission device is proposed which makes it easy to start on a slope. A control type slip clutch and a mechanical type control type two-way clutch are mounted between an input shaft to which the rotation of an engine is transmitted and an output shaft mounted around the input shaft. The input shaft and the output shaft are engaged together by the slip clutch while producing slip, and thereafter the two-way clutch is engaged. This improves transmission efficiency. A one-way clutch is provided between the output shaft and a housing provided around the output shaft. In a stopped state on an upward slope, when depressing of the brake pedal is released and rotation in the reverse direction to the revolving direction of the engine is transmitted to the output shaft from the vehicle wheel side, the output shaft is locked by the operation of the one-way clutch, thereby preventing the vehicle from moving in the opposite direction to the moving direction.

The present invention provides a data management program for performing monitoring so that user data provided to the client cannot be copied and utilized for a purpose other than the intended purpose.When a storage device (8) storing user data (3) is connected to a client computer (12), a management program (4) prohibits writing to all of the external storage devices. The management program (8) makes settings prohibiting usage of a network (7). The management program (4) performs control by acquiring the file name, folder name, and attribute data of the execution file as well as the process name and process ID of the process being executed. The management program (4) has built-in driverware (50) which runs in the kernel mode (15) of an operating system (21) and serves to provide a common interface for the communication of device drivers (35, 36, 42 to 44) and an application program (20).

A plate member is adapted to be electrically grounded. A first radiating electrode opposes the plate member with a gap and extending parallel to the plate member. A second radiating electrode opposes the plate member with a gap and extending parallel to the plate member. A feeding pin is connected to a center part of the first radiating electrode and a center part of the second radiating electrode. The feeding pin is adapted to feed power to the first radiating electrode and the second radiating electrode. A pair of first short-circuiting pins are electrically connecting the plate member and an outer edge of the first radiating electrode at symmetrical positions relative to the feeding pin. A pair of second short-circuiting pins are electrically connecting the plate member and both ends of the second radiating electrode. The first radiating electrode is formed with blank portions which are located at such positions that are on hypothetical straight lines connecting the feeding pin and the short pins. The first radiating electrode and the second radiating electrode are flush with each other.

摘要:
An object is to provide a shaft coupling which is short in axial dimension, which can transmit large power between shafts even if the offset amount of the shafts is large, and which is less expensive and can be assembled easily. The shaft coupling includes plates 1 and 2 fitted on ends of input and output shafts A and B, respectively. A plurality of guide grooves 5 and 6 are formed in the opposed surfaces of the plates 1 and 2, respectively, so that each of the grooves 5 and 6 extend perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves 5 and 6 of the plates 1 and 2 at a portion where the pair of grooves 5 and 6 cross each other. When the steel balls are pushed by the driving plate 1, they push the driven plate 2 while rolling in the guide grooves 5 and 6, with their movements restricted by a retainer 4 in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates 1 and 2, there are only the steel balls 3 and the retainer 4. Thus, the shaft coupling is sufficiently short in axial length, can be manufactured at a low cost, and can be assembled easily.
