Title: Transmitting system of digital signal
Inventor: TAN YOUICHI
IPC: H04L5/22
Filed: 1981-10-30
Abstract: PURPOSE:To decrease extremely the time required for control of connection, by designating previously the limit of time which is necessary for a called station to transmit an answer packet through a calling station and inhibiting the use of said time limit for the stations excepting the calling station to facilitate an easy answer packet for the called station. CONSTITUTION:A calling station finds out three idle blocks prior to the transmission of a packet and prepares a block 1 for calling packet and a block 2 for answer packet. Then the rear and front guard times b1 and b0 are set across blocks 1 and 2. The calling station monitors the block 2 and puts a dead pulse 4 into the latter half of the block sent from the called station when no answer signal is fed to the block. Thus the calling station informs the occupancy of the block to the stations excepting the called station and inhibits the use of this block for the stations excepting the called station in the subsequent frames. Thus the called station transmits an answer packet in an easy way.

Title: Resin spin welding member
Inventor: SHIBAYAMA TERUTSUGU
IPC: B29C65/06
Filed: 1986-07-23
Abstract: PURPOSE:To prevent excessive frictional heat from generating and consequently warpage and wrinkles from generating on the rear surface of a board by a method wherein ribs are provided on the front side of a flange part in a spin welding member having the flange part, which is to be welded to the resin board. CONSTITUTION:Ribs 13 are provided on the opposite surface 11b of the mounting surface 11a of a flange part 11 in a resin spin welding member having the flange part 11, a columnar part 11 and engaging projections 12 to be engaged with a rotary jig 16. Through the phenomena of 'heat transfer to rear surface' or of the generation of wrinkles, warpage and the like on the rear surface of a board 17 may occur due to excessive frictional heat when the resin board 17, onto which the flange part is welded, is thin, the provision of the ribs 13 on the front side of the flange part 11 prevents the above-mentioned phenomena of 'heat transfer to rear surface' from developing, because excessive heat is effectively dissipated through the ribs and does not be transmitted to the rear surface of the board 17.

Title: Brake valve for railway vehicle
Inventor: KINOSHITA TAKAO
IPC: F16K11/074
Filed: 1985-08-06
Abstract: PURPOSE:To prevent an increase in sliding resistance at a sliding surface between a valve and a valve seat by separating and removing graphite component at the upper surface portion of the valve seat to form a lot of vary small vertical concave portions, and accumulating lubricating oil in the concave portion. CONSTITUTION:A raw material cast iron is subjected to necessary machining, such as boring a supply and discharge hole 4 and the first outlet 3. Just after the surface portion of the machined valve seat 2 is heated up to about 850 deg. by a burner, the surface portion is dipped in quenching oil to be rapidly cooled. The quenching and tempering will cause the surface portion of the valve seat to fall off graphite, and increase hardness of the portion. After the flatness of the surface portion is increased, lapping is performed. At the time of lapping, graphite is removed to form concave portions. The concave portion 20 has a diameter of several mu and a depth of several tens of mu, and lubricating oil is accumulated in the concave portions 20.
