Title: Safety device for exhaust bypass type turbo-charger
Inventor: YAMADA KOUICHIROU
IPC: F02B37/18
Filed: 1977-11-18
Abstract: PURPOSE: To permit reliable detection and disposal regarding a failure of operation of an exhaust bypass valve by coupling an intake tube communicating compressor and diesel engine through a pressure switch to an alarm unit.  
     CONSTITUTION: A pressure switch 14 is provided on an intake tube 5 communicating a compressor 2 and a diesel engine 4, and the tip of a rod 14 of the switch is held in contact with a movable piece of a switch 15 connected to a solenoid controlled valve 22. With this arrangement, when the pressure in the intake tube 5 is extraordinarily increased with a failure of operation of an exhaust bypass valve 8, a diaphragm 18 is leftwardly moved against a compression spring 19 within an atmospheric air chamber to move the rod 20 to the left side so as to bring the movable contact 15 into contact with a fixed contact 15. As a result, the solenoid controlled valve 22 is excited to cause throttling of an oil supply pipe 23, thus reducing the rate of fuel supply from fuel tank 24 to engine 4 and also turning on an alarm lamp 25.

Title: Screw propeller blade for ship
Inventor: YUASA HAJIME
IPC: B63H1/18
Filed: 1980-10-04
Abstract: PURPOSE: To prevent exerting of the influence of vortexes produced in the proximity of a propeller shaft, by a method wherein guide vanes, being positioned separately from a propeller blade, are placed at a root part of the propeller blade.  
     CONSTITUTION: Guide vanes B3 are placed at intervals at a root part of a  propeller blade A, being positoned ahead of the rotation direction of the propeller  blade A. The guide vanes B3 function as a type of a vortex generator, and  vortexes, produced by the vanes, perform a role to erase the vortexes produced  around a propller shaft. The displacement of the vane by, for example, C>0.5tMAX  prevents contact of the vortexes, generated by the guide vanes B3, with the surface  of te propeller blade A but causes skimming of the vortex along the blade surface.

Title: Error recovery system of logical device
Inventor: IWAMOTO MITSUE
IPC: G06F11/14
Filed: 1980-10-03
Abstract: PURPOSE:To perform recovery processing efficiently by performing the stopping of execution, the reporting of an error, and the standing-by operation of internal state information when the CPU error occurs, by permitting the CPU to recover to the last state before the error occurrence by repairing a fault, and by starting retrying operation at the last point. CONSTITUTION:If the occurrence of an error in a CPU10 is detected by an error detecting circuit 130, a clock oscillating circuit 131 is stopped to freeze its internal state, and a recovery controller 20 is informed of the error occurrence to send the program-rewritable contents of register groups 111-119. An instruction retry indicator 132 judges whether the retrying of an execution instruction can be executed during the error occurrence to retry the instruction, but when it fails in the retrying owing to a fixed fault, the recovery controller 20 permits register information and the contents of a main storage device 30 to stand by in an auxiliary storage device 40 and the name of the faulty package is outputted on a console panel to disconnect the CPU10. After an operator repairs the fault, the recovery controller 20 recovers in the reverse order and then continues processing.

Filed: 1983-07-28
Abstract: PURPOSE:To incorporate the titled drier easily to an automatic treating process, and to dry a wafer readily by bringing the wafer into contact with and holding it to a stopper with the revolution of a rotary stage. CONSTITUTION:A semiconductor wafer 1 is placed eccentrically on a rotary stage 12 while taking a distance (e) between the central point of the stage and the central point of the semiconductor wafer, and three stoppers 13 are fitted in the direction of positional displacement of the semiconductor wafer 1. When the semiconductor wafer 1 having a 5 inch diameter is placed on the rotary stage 12 having a 150mm. diameter, the distance (e) is brought to 5mm.. Consequently, speed is increased slowly from the number of revolution of several dozen RPM up to the number of revolution of 5,000RPM first, and speed is reduced gradually and stopped lastly. According to such a usage, the semiconductor wafer can be held only by fitting the stoppers 13 only at one side end of the fringe of the rotary stage 12 because the semiconductor wafer is pushed against the stoppers and held by centrifugal force by revolution.
