Abstract: PROBLEM TO BE SOLVED: To provide a lens interchangeable camera, by which the cost can be reduced. SOLUTION: When a serial communication request (CSL='L') from a body side micro-computer is given for opening a serial bus to a data bug for printing data such as a date or the like in a film, a lens side micro-computer instructs not to perform communication by a serial bus (S331). The micro-computer transmits 'serial bus inoperable' to a lens and waits for the end of CSL='L', that is, local communication (S332-S333). If CSL='L', the micro-computer instructs release of a serial bus open instruction and returns.

Title: Liquid crhomatograph
Inventor: ITO TOSHIKAZU
IPC: G01N30/32
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent a rate-of-flow setting reaching the upper limit of pressure value by presuming the upper limit rate of flow by a max. rate-of-flow presuming means, comparing the obtained value with a new rate of flow set by a rate-of-flow setting means, and prohibiting such a setting operation that the new set rate exceeds the upper limitation. SOLUTION: The upper limit of pressure value P0 is previously stored in an upper limit pressure storing means 22. The rate of flow in the range where the pressurization will never become abnormal, is set by a rate-of-flow setting means 21, and the operation is conducted in normal condition. The set rate of flow F1 is stored in an at-normal set rate storing means 24. The liquid feeding pressure at this time is monitored by a pressure sensor 15, and the latest pressure value P1 is stored in an at-normal pressure storing means 23. Using the upper limit P0, set rate F1, and pressure value P1, the upper limit rate of flow F0 is determined from an expression P1/P0=F1/F0.  When a new input of the rate of flow is made by the setting means 21, a comparing means 26 compares the new set rate FS with the upper limit F0, and if FS is greater than F0, it is judged that an abnormal pressurization is likely, and the made setting is canceled 20.
