Filed: 1984-06-01
Abstract: PURPOSE:To transfer data in response to the state of transfer requests by providing a data section deciding point of time just before a data section and all data sections of the information requested for transmission by reserved information whose reception is finished from the data section deciding point of time for one preceding occassion until the data deciding point of time at the data set point of time. CONSTITUTION:Plural ground stations are arranged in a range possible for communication with a communication satellite to constitute an information transmission system and the satellite communication line is subjected to framing in time division. The satellite communication frame consists of a reservation section of a fixed time length and a data section of a variable time length. The data part deciding point of time deciding the time length of the data section is provided just before the data section. In transmitting information from the ground station of the system, the ground station transmitting the information uses the reservation section to transmit the reservation information requesting the information transfer to all the ground stations.

Title: Method for detecting fluid flow
Inventor: LOYD JOHN C
IPC: B41J2/185
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting the flowing state of fluid in an ink jet printer. SOLUTION: In the method for detecting the flow of fluid, a low speed air flow type catcher 18 is provided in order to form a bubble flow in a catcher vacuum port and a catcher return line 25. Pressure fluctuation of returning fluid is monitored in the catcher return line to an ink tank 30 having tank vacuum pressure. The tank vacuum pressure is lowered automatically to a predetermined level higher than the bubble flow forming level. Subsequently, the vacuum pressure of tank is lowered increasingly while monitoring the pressure fluctuation. When the pressure fluctuation 15 reduced lower than a predetermined level due to formation of a bubble flow, the vacuum pressure of tank is sustained at a constant level. The vacuum pressure of tank is increased by a predetermined level and the increased level is sustained as the operating point for the bubble flow of a printer.
