Title: Method and apparatus for restriction of access to file
Inventor: TOOMASU II KUUPAA
IPC: G06F12/00
Filed: 1995-04-19
Abstract: PURPOSE: To provide a method and device for protecting access to a specific file stored in a memory medium to which access can be performed by a computer. CONSTITUTION: Plural files including at least one enciphered file and at least one non-enciphered file are stored in a memory medium 213 to which access can be performed by a computer. The previously selected part of each enciphered file is recorded in the memory, a cryptoanalyzing block including information available for the cyptoanalysis of the file is generated, and the cryptoanalvzing block is integrated into the file instead of the previously selected part recorded in the memory. Afterwards, data processing system calling related with the files stored in the memory medium to which access can be performed by the computer is monitored by using a file management program. The file management program decides whether or not the called file includes the related cyptoanalyzing block, and the file is processed in a specific method according to the result.

Abstract: PURPOSE:To extremely simplify a structure and to effectively replace a tube by providing a supporting member and an engaging stop member, driving both of the members by one driver, and moving them to supporting and support releasing positions as well as engaging and disengaging positions. CONSTITUTION:When a vacant tube 8 of lowermost stage is detected by a sensor 29, a driver 22 is operated by its signal, an engaging stop member 35 is further operated, a tube of second stage is engaged to prevent it from dropping, a supporting member 32 is retreated to release the supporting state of the vacant tube 8 of the lowermost stage, thereby dropping the tube 8. Then, the driver 22 is reversely driven to move the member 32 to the supporting position. When the member 35 is retreated, the tube of the second stage is dropped on the member 32. Thereafter, chips P are fed from the tube to a tunnel unit. Thus, the tube can be effectively replaced.

Title: Turning angular speedometer of ship
Inventor: KOGURE SHIYOUICHI
IPC: G01P3/42
Filed: 1978-08-02
Abstract: PURPOSE: To make it difficult that a turning angular speedometer is affected by phase deviation and power source voltage fluctuation and make the turning angular speedometer small-size by obtaining a pulse output dependent upon the rotation of the axis of an originating synchro, which outputs bearing signals, to obtain turning angular speed signals according to turning directions.  
     CONSTITUTION: The voltage obtained in the stator winding of roiginating synchro 31 which outputs bearing signals is applied to input terminals S 1  to S 3  of Scott transformer 37 of transducer 36 to obtain output sinθ.sinωt and cosθ.cosωt. These outputs are subjected to synchronizing rectification by 46 and 47 to obtain sinθ and cosθ, and further, the output obtained by full-wave rectification is applied to attenuator 40 to obtain the ratio of a voltage proportional to sinθ to a voltage proportional to cosθ. This ratio is applied to comparators different in set value of comparator 41. Outputs of comparators are applied to gate circuit 45 together with respective outputs according to positive and negative of sinθ and cosθ, thus obtaining a pulse train. From the number of pulse trains per unit time, an output proportional to the turning angular speed according to the turning direction of the synchro axis is obtained.
