A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.

Abstract: A removable hard disk drive is detachable from a computer apparatus, and includes a storage medium for storing data from the computer apparatus and a communication interface with the computer apparatus. Upon reception of eject instruction issued by the computer apparatus, the removable hard disk drive writes contents cashed in a cache memory into a disk, and shifts to an ejectable state. Upon the completion of the shift to the ejectable state, the removable hard disk drive externally outputs an eject signal. A microprocessor which controls an eject mechanism executes removable hard disk cartridge eject operation in response to the eject signal.

Abstract: There is provided a portable storage device which makes it possible to largely reduce time that is taken to remove the storage cartridge that is inserted and cannot be handled. A removable hard disk cartridge contains a hard disk and a control circuit for control of writing and reading of data in and from the hard disk in a casing thereof. A main unit includes an automatic loading/ejecting mechanism that receives the hard disk cartridge into a predetermined inner position within the main unit and ejects the same out from the position, and a microprocessor that controls storage operation for storing data in the hard disk cartridge. Before the automatic loading/ejecting mechanism performs a receiving operation, it is determined whether access to contents recorded on the hard disk can be gained, and when the access cannot be gained, the receiving operation by the automatic loading/ejecting mechanism is inhibited.

Abstract: An information processing system which is capable of promptly authenticating a combination of a disk array device accommodating a plurality of disk devices, and an information processing apparatus in which the disk array device is mounted. A first control section of a cartridge device as a disk array device stores ID information for use in authentication by an information processing apparatus, and a second control section of the information processing apparatus acquires the ID information from the first control section. The second control section authenticates the cartridge device by using the acquired ID information. A third control section of the information processing apparatus reads out information from hard disk devices contained in the cartridge device when the authentication by the second control section is successful.

Abstract: This invention can reliably prevent removal of a disk unit by a person other than an authentic user while enabling sharing the disk unit between a plurality of users. An HDD unit (20) detachable from an information processing apparatus incorporates a memory which stores user information for user authentication, and a CPU which performs authentication processing by using the user information. If eject of the HDD unit (20) is designated, the HDD unit (20) executes authentication processing on the basis of authentication information input from the information processing apparatus in which the HDD unit (20) is mounted, and the user information stored in the memory. The HDD unit (20) notifies the information processing apparatus whether to permit/inhibit eject processing. If eject processing is permitted, the information processing apparatus ejects the HDD unit (20) by using a lock mechanism (21), motor controller (23), and the like.

Abstract: An adjustment structure for the cushion unit of a snowmobile suspension system. The adjustment arrangement includes a mounting for the cushioning unit that is defined by a bolt and a pair of mount brackets having guide apertures formed therein. The bolt and guide aperture surfaces are treated so as to avoid shifting of the mechanism under the weight of the snowmobile when the mounting bolt is loosened for adjustment purposes.

Abstract: A communication apparatus is provided with an element for reading out information signals recorded on a medium. The reading element includes a reproducing portion for reproducing the signals recorded on the medium and a processing portion to process the reproduced signals. The information signals are temporarily stored and sequentially transmitted. Electric power to the reading means is controlled when the information is transmitted through a communication line.

Abstract: An image transmitting apparatus for digitizing a still-picture television signal, a manuscript image signal or the like and transmitting the digitized signal over a line is adapted to read an analog image signal stored in video memory such as a video disk, convert the read analog image signal into a digitized multi-valued signal and store the multi-valued image signal in an image memory. On the basis of paper size on which printing is to be performed by an apparatus, such as a facsimile machine, on the receiving side, the number of pixels constituting the multi-valued image signal stored in the image memory and an ensuing binary coding method, a ratio is obtained at which the multi-valued image signal stored in the image memory is to be expanded or compressed, and the multi-valued image signal is expanded or compressed based on this ratio.

Abstract: A hydrostatic transmission utilized in a tractor that drives a mower attachment. The hydrostatic transmission includes a control shaft that is operated through a linkage system from a shift control lever. An adjustable detent operates directly on the control shaft for locking the control shaft in its neutral condition. The linkage system includes a lost motion connection so that the detent can operate without having to move the linkage system or the shift control lever.

Abstract: A signal processing device detects information drop-out parts of an incoming information signal by dividing the information signal received for a given period of time into an n number (n: an integer which is at least 2) of blocks and by forming an information drop-out part signal indicating a part that has an information drop-out within each of the blocks. The device is thus arranged to be capable of promptly finding the parts of the information signal having information drop-outs.
