Abstract: A method of testing ICs in parallel is capable of receiving a state signal from handlers to estimate process start times of the handlers, and of changing a test start request interruption wait time. Automatic carriages automatically supply and accommodate IC issue test start request interruption signals to an external device control circuit of an IC tester. IC testing stations execute tests of ICs at the same time. When the test start request interruption signals are not issued from all the automatic carriages, a computer of the IC tester reads an operating state of the automatic carriages which do not issue the test start request interruption signal so as to judge whether the automatic carriage is in a significant wait condition. The IC testing stations immediately execute the test of ICs if the automatic carriages are not in the significant state.

Abstract: An information processing apparatus uses a triad-based state transition model which is implemented in a state machine for making rational determinations on the state of a system of interest and for controlling the same to an appropriate state. The triad-based state transition model is stored in a memory unit of the apparatus and made up of a first group of states for defining natural behavior of the system to be controlled irrespective of forced actions; a second group of states for defining forced actions for directing the behavior of the system to be controlled to a target; and a third group of state for defining target states to which the system to be controlled may proceed from the first group of states as a result of determining natural behavior of the system based on a first predetermined threshold value, and as a result of determining a change in the system behavior due to a forced action based on a second predetermined threshold value.

Abstract: A printer for use with an ink ribbon having at least two printing tracks is provided with a print head that moves along a predetermined path adjacent to a recording medium. A line driver reciprocates the print head along the path in first and second directions. A multi-track ribbon comprises a plurality of printing tracks having portions thereof disposed between the print heads and a recording medium. A ribbon shift mechanism positions a preselected one of the tracks on the ink ribbon adjacent the print head for use in printing a response to movement of the print head. The ribbon shift mechanism comprises a printing track setting mechanism for moving the ribbon in one direction to set at one desired track height from among several preselected track heights corresponding to a selected one of predetermined amounts of movement of the print head in the first direction to a first end portion of the path.

Abstract: A compact, lightweight printer capable of using multi-track ink ribbons that facilitates multicolor printing, without having a dedicated track switching drive system. The printer employs a printing track setting member that is activated by contact pressure from a print head carriage when it moves in one direction and vertically displaces a ribbon frame supporting the ribbon to one of several preselected heights with respect to the print head. The setting member is preferably made in the form of a setting lever with a drive end for interacting with the print head carriage and a setting end with a series of setting height stops that interact with the ribbon frame. Rotation of the setting lever places different setting level stops under the frame which varies its height accordingly.
