Abstract: PROBLEM TO BE SOLVED: To provide a disk device diagnostic system with which a disk device in on-line state can be diagnosed without separately preparing a similar disk device for separately storing data stored in that disk device. SOLUTION: A disk device 13 is connected through an on-line disk diagnostic device 12 to a maintenance operating device 11 and stores data to be handled by this device 11. The disk device 13 divides a data storage area 22 into N pieces of areas, the area of a block number stored in a diagnostic pointer block 21 is defined as a block area 24 for diagnosis and by copying data in a diagnostic object block area 25 to be diagnosed into this block area 24, the read/write of the diagnostic object block area 25 is diagnosed. After diagnosis, the diagnostic object block area 25 becomes the block area 24 for diagnosis and the respective block areas are diagnosed while being successively shifted. Therefore, the diagnosis in on-line state is enabled without especially preparing any disk device.

Title: Substrate for thermal head and manufacture thereof
Inventor: NISHIOKA YOICHI
IPC: B41J2/335
Filed: 1988-06-24
Abstract: PURPOSE:To improve heat retaining properties and heat-resisting properties while enabling printing operating at high speed and having high quality by forming a heat storage layer shaped onto an insulating substrate of the sintered body of boehmite powder having specific grain size. CONSTITUTION:A heat storage layer 2 is formed onto an alumina substrate 1 as an insulating substrate, and the heat storage layer 2 is shaped of the sintered body of boehmite powder having grain size of 1mum or less. Since the heat storage layer 2 is composed of the alumina sintered body having a large number of fine holes, has excellent heat-resisting properties and has fine holes, it has small thermal conductivity and properties superior in heat retaining properties. Consequently, even when the heat storage layer 2 is thinned, sufficient heat retaining properties can be acquired. Since the heat storage layer 2 can be thinned, the speed of heat dissipation of a heating element formed onto the heat storage layer 2 is accelerated, thus increasing printing speed.
