IPC: F25B9/14
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To restrict wearing of a seal member and attain a long life of gas compressing expansion machine by a method wherein there are provided a second seal member having a higher sealing characteristic against a flow in a direction from a working chamber to a driving chamber than that for the flow opposite to the former flow and a plenum chamber between the second seal member and the intermediate chamber. SOLUTION: Since the second seal member 93 is made such that a higher sealing characteristic of flow in a direction from a working chamber 21 to a crank chamber 12 than a sealing characteristic of flow opposite to the former flow is set, oil 10 flowed from the crank chamber 12 is held in a plenum chamber 94. In addition, an intermediate chamber 92 is arranged between the plenum chamber 94 and a first seal member 91, the oil 10 stored in the plenum chamber 94 is not directly splashed to the first seal member 91 as a piston rod 22 is reciprocated and its volume more than that required is supplied to the first seal member 91 so as to prevent the oil from being flowed into the working chamber 21. With such an arrangement as above, it is possible to suppress wearing of the first seal member 91 and attain a long life of the device.

Title: Scsi controller and scsi bus system
Inventor: OE ICHIRO
IPC: G06F13/38
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To simultaneously transfer the same data to plural targets in a single transfer sequence. SOLUTION: A mode selection part 2 switches a switch 3, a gate 4 and a control signal monitoring part 5 to select a normal mode or a subsidiary target mode. The part 5 monitors the control signal such as an MSG(message) signal, etc., to identify the bus phase such as a selection phase, etc., and notifies a selection/reselection recognition part 6 and a data input/output part 7 of the present phase in a subsidiary target mode.

Then the part 6 recognizes in a subsidiary target mode the selection of a main target and a fact that the main target reselected the initiator.  As a result, an SCSI (small computer system interface) controller fetches the information transferred to an SCSI bus 1 from the initiator synchronously with the transfer of information that is performed between the main target and the initiator in a subsidiary target mode.

Title: Inspection of reticle
Inventor: OHASHI NORIKO
IPC: H01L21/66
Filed: 1988-10-27
Abstract: PURPOSE:To shorten a production period of a semiconductor with a reduction in reticle defect inspection time by comparing a defect memory data as comparison between a reticle before a partial correction thereof and that thereafter with a design data of a corrected part alone. CONSTITUTION:A reticle 1a before a partial pattern correction and the reticle 1b thereafter are placed on an X-Y stage 2 and moved at a uniform speed. The reticles 1 are irradiated with a light source 5 and light signals obtained through a lens 6 are converted into comparison signals with an opto-electro transducer section 7 to be compared. Hence, reticle defect information is stored into a buffer memory 9a. On the other hand, an original pattern data for a corrected part alone stored in a magnetic tape 10 is converted by a converter section 11 into a comparison signal to be compared with a data in the memory 9a by a comparison section 8b and defect information is stored into a memory 9b to be outputted to an external output 12. This enables a reduction in the production period of a semiconductor with a shorter inspection time of a reticle defect.
