Title: Data transmission system
Inventor: OKA NOBUYUKI
IPC: H04L1/00
Filed: 1983-12-01
Abstract: PURPOSE:To improve a data transmission percentage and to reduce an incorrect receiving percentage in mobile radio communication by detecting a trigger pattern on the receiving side, after a prescribed time, inputting plural words and deciding the majority on the basis of respective corresponding bits dividing the plural words at prescribed intervals. CONSTITUTION:A clock CLK reproduced from a receiving signal is inputted to a trigger pattern detecting circuit 10 to form the reading timing of receiving data RD. The detecting circuit 10 inputs respective bits of the receiving data RD sequentially read out at said timing simply to an 8-bit shift register, and if the shift register is filled with the bits, discharges the older bits successively from the shift register until the 8 bits in the register coincides with the trigger pattern TR. At the time of coincidence, a counter 12 counts the number of clocks CLK. Counting up the number of bits corresponding to one word, a counter 12 outputs a signal S2 to allow a data storage circuit 14 to input the receiving data RD sequentially. Since a TR period repeating the same pattern plural times is regarded as a trigger point and 5 words are inputted unconditionally after an idle time, the receiving percentage is improved.

Title: Valve drive for engine
Inventor: MATAYOSHI YUTAKA
IPC: F01L1/14
Filed: 1989-09-04
Abstract: PURPOSE:To restrict the wear of a cam and a lifter and reduce their sizes by forming a follower portion of a lifter in sliding contact with the cam in a spherical shape, and forming the cam surface in sliding contact with the lifter of the cam with an arcuate curvature. CONSTITUTION:At the time of engine operation, a lifter 3 in sliding contact with a cam surface 8, following the rotation of a cam shaft 11, reciprocates within a fitting hole 5, while compressing a valve spring 6 and allowing it to expand, to drive a valve 1 to be opened and closed. If the amount of lift of the valve 1 is increased here, the travel amount during which the cam surface 8 of a cam 2 is in contact with the follower portion 7 of the lifter 3 increases, necessitating an increase in the diameter of the lifter 3 accordingly. However, since the follower portion 7 is formed with a spherically curved surface, the diameter of the lifter necessary for securing a specified travel amount need not be increased. Because the cam surface 8 is recessed with an arcuate cross section to secure a specified contact width L, contact surface pressure is reduced.
