Patent JP-H0216848-A (JP)
Title: Operation expert system
Inventor: OYAMADA SATOSHI
IPC: G06Q10/04
Filed: 1988-07-04
Abstract: PURPOSE:To automatically diagnose a fault and to instruct repair to a maintainer by integrating expert systems on print boards. CONSTITUTION:In the case of a parity error, for example, a bus 2 and the print boards(PB) 10 and 11 which have used the bus 2 at the time of detecting the fault are assumed to be in a suspected range. On the other hand, device parts 13-15 are identified to be in what kind of states they are at the time of detecting the fault. A knowledge base 28 which is externally fitted collects information on a process in which the cause of the fault is assumed, and state information of PB10-12, analyzes them, decides the means and the process of the diagnosis of a fault device. A decision result is transferred to the built-in expert systems(BES) 19-21 together with the diagnosed result, and BES 19-21 analyze information on the cause of the fault and the decision result and selects a test string. Test data for verifying the normality of the device parts 13-15 select and execute test terms from data in the knowledge bases 22-24 in response to the purpose of inspection.

Title: Magnetic tape storage device
Inventor: GOMI MUNECHIKA
IPC: G11B15/087
Filed: 1980-11-28
Abstract: PURPOSE:To prevent an error in writing due to tape deformation by delaying a next data write command when a magnetic tape is in a stand-by state continuously for longer than a prescribed time, and starting the writing operation after the tape part is jumped over. CONSTITUTION:When the time interval of a tape run instruction signal A exceeds a time T1, a latch output signal (c) is inputted to an AND gate 12. Then, when the tape run instruction signal A is generated, the run instuction signal A and a written signal D are inputted to the gate 12 to output an energizing signal F having time width T2. This signal F permits an AND gate 15 to stop the write permit signal K of a magnetic tape storage device for a time T2 and also to output a new delayed write permit signal L, and consequently writing to a magnetic tape is delayed by the time T2, thereby avoiding writing data at a deformed tape part. Consequently, errors in writing due to tape deformation is prevented.

Title: Plunger pump
Inventor: HORI TOSHIAKI
IPC: F04B9/04
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce the wear and heating of structural parts resulting from increase in friction resistance by preventing increase in friction resistance between a rotating cam and a member on a plunger side when a cam mountain of the rotating cam is put about its top in abutting to the member on the plunger side. SOLUTION: On the sliding face of a cylinder 12 with respect to a plunger 13, a passage hole 22 having one end communicating with a suction passage 17 is formed to be open. A communication passage 25 communicating a pump room 14 with the siding face is formed in a plunger 13 so that the communication passage 25 communicates with the passage hole 22 when the plunger 13 is displaced to a predetermined position in front of a top dead point. When the contact portion of a rotating cam 8 approaches the top (t) of a cam mountain 9 and the plunger 13 is displaced to the determined position in front of the top deaf point, pressure in the pump room 14 is released through the communication passage 25 and the passage hole 22 to a suction passage 17. At this time, friction resistance between the rotating cam 8 and a member on the plunger side is reduced.

Title: Microporous membrane
Inventor: SASAKI JUN
IPC: C08J9/28
Filed: 1985-07-27
Abstract: PURPOSE:To reduce the filtration resistance, to increase the filtration flow rate and to prevent the deterioration in the filtration performance due to the loss of the surface by using a microporous membrane with the pore diameter distribution in the thickness direction and having a smallest pore diameter layer at the inside of the membrane. CONSTITUTION:A polymer such as polyvinylidene fluoride is dissolved in the mixture of a solvent such as dimethylacetamide and a nonsolvent such as polyethylene glycol and polyvinyl pyrrolidone to prepare a film forming soln. The soln. is extruded from a slit in specified thickness onto a web carrier and spread and the spread film is dipped in a liq. coagulant, when the separation of the micro phase due to the evaporation of the solvent is generated only in the vicinity of the spread film. Consequently, a microporous membrane with the pore diameter distribution in the thickness direction and having the smallest pore diameter layer on the inside of the membrane is produced. The polymer soln. released from the liq. coagulant and having a self-supporting property is stripped from the carrier, washed with water and then dried.

Title: Personal computer which identifies attaching and removing type medium
Inventor: ARAN FUREDERITSUKU AANORUDO
IPC: G06F3/06
Filed: 1991-06-13
Abstract: PURPOSE: To discriminate attachment/detachment media in plural types by discriminating the type of a medium inserted into a device for communication by a controller by using at least several of plural signal communication paths. CONSTITUTION: The storing capability of a medium inserted into an discriminated storage device having a function which can be easily judged is judged by using a pair of paths which are not used due to reservation or which are used for a grounded return for ensuring the insulation of the other signal. In this case, a path 17 is changed from the grounded return path to the path for a first medium type indicator, and a path 9 is changed from the grounded return to the path for a second medium type indicator. A signal indicating that any driving mechanism type is not present on the pair of paths is discriminated.

Filed: 1983-09-14
Abstract: PURPOSE:To smoothly conduct turning and boom operation in parallel with each other by introducing the first pilot pressure and the second pilot pressure into a pilot switching valve so that the initial turning is conducted without delay, and after the start of turning, a boom is quickly operated. CONSTITUTION:In a pilot switching valve 9, the first pilot pressure introduced from the first fluid pressure actuator circuit 4 exerts upon the spring 16 side, and a fluid fed with pressure by a switching valve 19 adapted to open interlocking with the opening of a switching valve 7 for a boom cylinder exerts upon the pressure spring 15 side as the second pilot pressure. If the working fluid has high pressure for producing large turning torque required for the initial turning, a hydraulic motor for turning is separately operated by the total output of the first hydraulic pump. When the first pilot pressure becomes lower than the second pilot pressure, the pilot switching valve 9 is opened to let a part of the working fluid in the first hydraulic pump system in the second hydraulic pump system, thereby operating the boom cylinder.

Abstract: PURPOSE:To attain smooth vibration of a vibration system by providing a throughhole whose outer diameter is specified to the center of a flat diaphragm. CONSTITUTION:The outer diameter D of the throughhole 10a provided to a flat diaphragm 10 is larger than the outer diameter d1 of the 1st bobbin 5, and smaller than the outer diameter d2 of the 1st sub cone 7. Thus, a 1st space A of a 1st magnetic circuit 1 and a 2nd space B of a 2nd magnetic circuit 11 are communicated and when the 1st space A is expanded, the 2nd space B is compressed and since the 2nd space B is expanded with the 1st space A compressed, the total volume of the 1st space A and the 2nd space B is always constant. Thus, the air in the 1st space A and the 2nd space B is not compressed and expanded, then the vibration of the vibration system is not suppressed but smoothed.
