Title: Forming method for metallic matrix complex
Inventor: JIYON TOOMASU BAAKU
IPC: C22C1/10
Filed: 1989-11-10
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. Particularly, a permeable mass of filler material is formed into a preform (1). An infiltration enhancer and/or infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the preform (1) at least at some point during the process, which permits molten matrix metal (5) to spontaneously infiltrate the preform (1) when the preform (1) is placed into the molten matrix metal (5). A means (4) for maintaining the preform (1) at least partially below the surface of the molten matrix metal (5) can also be utilized.

Abstract: PROBLEM TO BE SOLVED: To hold negative pressure even in supplying ink by preventing flow-out of ink from an orifice by providing an ink reservoir vertically above the orifice, and providing a blower for setting internal pressure to negative pressure of the atmospheric pressure or less and an ink supply hole to be opened only at the time of supplying the ink. SOLUTION: An ink reservoir 11 is disposed above a vertical direction of an orifice 1. A blower 13 is mounted at the reservoir 11 and controlled to be rotated to exhaust the air therein. The reservoir 11 is held so that the air pressure therein is a negative pressure of about 5mm to 1,000mm of water column with respect to the atmospheric pressure. An ink supply hole 14 is normally blocked by an elastic cover 15, and held at the negative pressure. Meanwhile, at the time of supplying the ink, the hole 14 is blocked by an ink cartridge so that no air flows from the outside. Accordingly, the reservoir 11 is always held therein at the negative pressure to prevent the ink from being discharged from the orifice 1.

Title: Error rate display device
Inventor: NAKAYA HIDEO
IPC: G11B20/18
Filed: 1992-10-30
Abstract: PURPOSE:To provide an error rate display device capable of displaying an error rate with high sensitivity. CONSTITUTION:An error count value with (n) bit from a register 2 is supplied to a ROM 30 constituting a conversion table for converting data into a level signal as an input address. The level signal with (m) bit outputted from ROM 30 is supplied to an LED array 5 through a buffer 4. The (m) LEDs on the array 5 are driven by respective bit signals of the level signals with (m) bit respectively, and a count value is level displayed by the number of emitting pieces of the LEDs. The count value is converted to the level signal in logarithmic in the ROM 30. The display of the error rate is performed with high sensitivity since the variation amount of the error rate appears excellently on the array 5 because convertion is performed so that the change of the level signal becomes larger compared with the change of the count value when the count value of an error is small in the ROM 30.

Title: Active matrix type liquid crystal display device
Inventor: TANUMA SEIJI
IPC: G02F1/136
Filed: 1988-11-18
Abstract: PURPOSE:To prevent an ever-off point defect from spreading to the peripheral part of the defect even if the defect is present by separating an orienting film on the side of an active element substrate into independent picture element parts in constitution which has liquid crystal sandwiched between the active element substrate and a counter substrate. CONSTITUTION:If a picture element which is held insulated from a write bus WB (ever-off point defect) is caused, a different optical state as compared with normal picture elements is entered and charges migrate around to peripheral picture elements from the ever-off point defect through the orienting film 4 to cause variation in the potential of the picture element electrode E of the peripheral part. Namely, the orienting film 4 on the side of the active element substrate P is separated into independent picture elements to prevent picture elements from being connected by the orienting film 4. Therefore, even if the ever-off point defect picture element is generated, the path where the charges migrate from the orienting film of the picture element around to the orienting film of an adjacent picture element is cut off, so the charges are prevented from migrating around. Consequently, the display defect never spreads.

IPC: F17D5/02
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a fluid interrupting device enabling highly reliable remote interrupting control and a remote interrupting system using it. SOLUTION: The system includes a plurality of governor chambers 102 and a central monitoring portion 101 capable of two-way communication with the governor chambers 102. The central monitoring portion 101 monitors the condition of disaster in each block and transmits a remote interruption command selectively to each governor chamber 102. In each governor chamber 102, a communication device 10 determines whether the communication of the remote interruption command is true or false, after which, based on earthquake information sent from an SI sensor 14 and a mechanical earthquake sensor 15, a signal control device 11 opens a gate only when governor interruption is surely required, thus receiving a remote interruption signal and checking a sequence (ciphers) for final determination as to whether or not the command is true or false.  When the command signal indicates true ciphers, the signal control device 11 executes forced interruption of the governor via the SI unit 12.
