Title: Resource state monitoring method and information processing system
Inventor: RICK ALLEN HAMILTON II
IPC: G06F11/30
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To provide the method for monitoring resources of the information processing system as to various states exceeding a permissible range and the device for actualizing the method. SOLUTION: A continuous count of a fault read is held and only when the number of reads of fault states exceeds a specific fault repetition constant, that is reported to an operating system to perform proper operation. If a resource is discriminated as a fault resource in advance and then an 'excellent' read is made, the resource identifier is changed from a 'fault' state to a 'intermittent fault' state. Consequently, when successive 'excellent' reads exceed a specific success repetition constant, the resource is excluded from the 'intermittent' state and the monitor process is carried on.

Abstract: PROBLEM TO BE SOLVED: To obtain a printer having an adjustable interval between a head and a platen in which a print start position can be set accurately even for a thick sheet, e.g. a sealed letter, by an arrangement wherein the position of a carriage and a carriage position detecting means can be varied synchronously. SOLUTION: When an adjust lever 22 is stopped to a fixed frame 15 while inclining forward, the forward part of a carriage 10 carried on a guide shaft 17 by means of an eccentric pin 16 sets a lowering position to shorten the interval between a head 11 and a platen 12 thus setting an interval suitable for a thin sheet S1. In this regard, a detection flag 23 is located substantially in the center of the gap 20A of a home position sensor 20. At the time of printing a thick sheet S2, e.g. a sealed letter, the adjust lever 22 is inclined rearward and held at a specified rearward inclining position by a stopping means. Consequently, the carriage 10 is elevated along with the detection flag 23 and located at a home position corresponding to the sheet S2.
