Title: Cell subculture device
Inventor: TAKAOKI MUNEO
IPC: C12M1/00
Filed: 1993-02-17
Abstract: PURPOSE:To provide a device capable of conducting cell subculture with light labor and reduced risk of microbial contamination. CONSTITUTION:Plural laboratory dishes 1 are laterally aligned. Above them, a supporting bar 5 is set up and fitted with plural sheets 2 for cell transplantation corresponding to the respective dishes 1. This bar 5 is attached to a cam 7, which, in turn, enables the reciprocating motion of the bar 5 in its axial direction by turning a knob 8. A culture fluid is put into the dishes 1; when the dish 1 at the left end is inoculated with cells, the cells are then gradually proliferated and transferred to the transplanting sheet 2 there. In this state, on displacing the bar 5 right, the sheet 2 with the cells transferred thereto enters the adjacent right dish 2, effecting transplantation of the cells thereto. In this way, by conducting the reciprocating motion of the bar 5 each for a specified period of time, cells are transplanted successively to the right dishes, thus proceeding with the objective cell subculture.

Title: Data communication system
Inventor: ASOU FUSAYOSHI
IPC: H04L29/00
Filed: 1980-03-06
Abstract: PURPOSE:To prevent the occurence of failure, by identifying the character pattern even if failure data due to noise is produced, after the transmission/reception by one terminal device in the data communication using multiplexer. CONSTITUTION:When the data transmission from a terminal device 15 is finished, the multiplexer 8 is the status STX waiting state (a). With this state, all the patterns other than STX pattern are neglected, and when a pattern in matching with it is detected, the state moves to the SA(Station Address) pattern waiting (b). With this state, when the data in the SA pattern is received, the state moves to the DA (Device Address) waiting state (c), but if STX pattern is received, the state remains and in case of the patterns other than them, the state returns to the status (a). BCC(Block Check Code) waiting state is made next to the status (c). Thus, it is prevented to transfer failed data on the relay lime, allowing to increase the usage efficiency of the relay line.
