Title: Data link layer protocol for transport of atm cells over a wireless link
Inventor: AYANOGLU ENDER
IPC: H04W88/08
Filed: 1996-08-29
Abstract: The present invention is a reliable data link layer protocol to transport ATM cells over a wireless point-to-point link. The protocol ensures that the cells are transported reliably by use of a sliding window transport mechanism with selective repeat automatic repeat request (ARQ) and forward error correction (FEC). The protocol minimizes ATM header overhead by means of header compression and provides per-cell FEC whose size can be changed adaptively. The protocol also provides parity cells for recovery from errors that cannot be corrected using the per-cell FEC field. The number of these cells as well as the size of a window or frame can also be adaptively changed. In addition, the window can be terminated to request an immediate acknowledgment

Filed: 1995-11-24
Abstract: A time-division still picture communication system through which users can select necessary frames with a simple constitution. Natural still picture frames including reference frames are repeatedly transmitted in a fixed order by using the reference frames as the reference. A user device finds the reference frames, counts the reference frames, confirms the relation of the frames desired to be displayed, and displays the desired frames. For selecting the frames, only the information about the still picture being displayed is displayed. The number of all still pictures transmitted for one period determined by the reference frames may be additionally displayed together with the information. The still picture frame information is inserted into the voice band corresponding to a reference still picture, or into the voice band corresponding to several still pictures. Alternatively, an identification signal is inserted into the voice band corresponding to all the still pictures. Still picture frame information inserted into the voice band includes the three kinds: the sound signal inserted into the main voice band, the sound signal inserted into an auxiliary voice band, and appropriate control signals inserted into the auxiliary voice band.

Title: Valve operating system in internal combustion engine
Inventor: KAJIWARA SHIGEMASA
IPC: F01L13/00
Filed: 1997-11-18
Abstract: A valve operating system includes a connection switch- over device provided in a plurality of cam followers. The connection switch-over device has a piston moved in response to a change in hydraulic pressure in a hydraulic pressure chamber. A roller shaft is disposed on at least one of the cam followers and has a roller carried thereon to come into rolling contact with a valve operating cam. In this valve operating system, the hydraulic pressure chamber and a communication passage, which permits an oil supply passage to communicate with the hydraulic pressure chamber, are defined in a particular one of all the cam followers, which moves a smallest amount when the connection switch-over device is in its disconnecting state. The roller shaft, having the roller rotatably carried thereon, is mounted on the cam follower other than the particular one cam follower.          Thus, it is possible to avoid an increase in size of the particular one cam follower, and avoid a complicated assembling operation and passage construction. Moreover, the valve operating load is reduced to a minimum by using the roller.
