Filed: 1988-09-12
Abstract: PURPOSE:To increase processing speed for the input/output interruptions of a guest virtual computer and at the same time to improve the reliability of a virtual computer system to the input/output faults by using a guest input/ output subclass mask and a setting/resetting means for input/output interruption factors. CONSTITUTION:The guest input/output subclass masks 12 and 13 are used so that the change of a virtual input/output subclass mask performed by a guest virtual computer is directly reflected on the input/output interruption accepting state produced by the input/output subclass mask of a host computer. Then a means is added to decide the guest/host relation at high speed in an input/ output interruption process carried out in an active state of the guest virtual computer. Furthermore another means is used to set/reset an input/output interruption factor latch 14 corresponding to an optional input/output subclass. In such a constitution, no special process is required to a microprogram and a host program at decision of the guest/host relation. Then the input/output interruption of a guest virtual computer can be changed to that of the host computer. As a result, the performance and reliability are improved in a computer system.

Title: Optical switch
Inventor: WAKABAYASHI HIROHARU
IPC: G02B27/28
Filed: 1982-12-27
Abstract: PURPOSE:To improve the reliability of a switch by inserting a converting means for polarized components selectively between the output of the 1st prism which separates input light into plural polarized components and the input of the 2nd prism which puts those polarized components. CONSTITUTION:Light from an incidence optical path 2 is separated by a polarizing prism 6 into a P wave component to an optical path 12 and an S wave component to an optical path 10. When those components pass through half-wavelength plates 13 on the optical paths 11 and 10, the P wave component is converted into the S wave component and the S wave component is converted into the P wave component. Consequently, the polarized wave component at the input terminal of a polarizing prism 2 is in a state shown by (a) as a result of this polarization conversion and the light generated by mixing both components is outputted to a projection optical path 3. Thus, two states (a) and (b) are produced to obtain the functions of an optical switch. This constitution improves the reliability of the optical switch.

Title: Emergency cutoff valve
Inventor: NAMAKI TOSHIYUKI
IPC: G05D7/00
Filed: 1988-09-10
Abstract: PURPOSE:To execute excellent emergency cutoff during the occurrence of an abnormal situation by a method wherein through automatic control of a drive type low rate set means by means of an automatic control part, the energizing force of an energizing means for setting a cutoff flow rate is varied and a set flow rate is changed with a time so that it is maintained at a proper value in a state to match an actual change in a flow rate. CONSTITUTION:Set flow rate varying means A and B are provided for automatically changing a set flow rate, being to be cutoff for emergency, with a time based on information from a sensor S for detecting a flow rate. Thus, by automatically changing a set flow rate at a similar tendency to that of an actual change in a flow rate, a difference between an actual flow rate and a set flow rate can be always reliably maintained at a proper value. When a measurement flow rate by the sensor for detecting a flow rate is increased to a value higher than a set flow rate by a setter, emergency cutoff being executed can be realized at a normally proper timing. Even when an electric system is brought into a stop state due to outage, emergency cutoff is executed reliably.
