Title: Double write control system
Inventor: MUTO YOSHIAKI
IPC: G06F12/08
Filed: 1990-03-19
Abstract: PURPOSE:To shorten a copying time by pre-reading in advance difference data (track) copied to an input/output device in which a fault is eliminated from a normal input/output device before a host device (OS) reads it out, and storing it in a disk cache memory, at the time of transferring from a non-dual state to a dual state. CONSTITUTION:A disk device (DKU) 231 and 23a are dualized each other, and in the course of input/output processing, it is assumed that for instance, the DKU 232 becomes unable to read and write due to a fault. In such a case, in a cache 225, record data of a track to be read out by a copy processing executed continuously is read out already from a normal DKU 231 and stored in advance before a read-out command from an OS 201, and it will suffice that the record in this cache is read and only copied to the DKU 232 whose fault is repaired. In such a way, the time required for positioning a head in a track on the disk of the DKU 231 is eliminated, and the copy processing time is shortened.

Title: Clock monitor circuit
Inventor: NISHIKAWA MASAHARU
IPC: H03K5/19
Filed: 1978-06-02
Abstract: PURPOSE:To secure an easy monitoring for the clock fault by obtaining the OR for the terminal voltage of the capacitors which are charged by the high and low levels of the clock respectively. CONSTITUTION:When capacitor 8a is charged in a high level by clock input 1, the other capacitor 8b is discharged. While when capacitor 8b is charged in a low level, the other capacitor 8a is discharged. Accordingly, the clock fault can be detected with variation of OR output 5 by deciding the time constant properly for resistances 9a and 9b plus capacitors 8a and 8b and then obtaining the OR for the terminal voltage between capacitors 8a and 8b.

Filed: 1990-03-17
Abstract: PURPOSE:To reduce smoke generation by afterburning of soot in a cavity by connecting the cavity to an annular hollow space provided inside a piston by means of communicating paths. CONSTITUTION:A fuel injection nozzle 6 is arranged so as to face a cavity 5 formed at a central portion of a top of a piston 4. In this case, an annular hollow space 7 is formed inside the piston 4 so as to surround the cavity 5. The hollow space 7 and the cavity 5 are communicated with each other through communicating paths 8. By this constitution, combustion gas, which has flowed into the hollow space 7 through the communicating paths 8, flows out reversely from the hollow space 7 to the cavity 5 almost at the end of combustion in the cavity 5. This accelerates afterburning of the soot, and as the result, reduces smoke generation.
