Title: Data base processing system
Inventor: HAYASHI TOMOHIRO
IPC: G06F12/00
Filed: 1990-05-11
Abstract: PURPOSE:To reduce cost for storing collected data and to improve the concurrency of transaction by handling a log data as the storage structure of a data base processing to mainly insert the data. CONSTITUTION:A log data procession part 14 possesses the data inputted from a terminal 11 by a transaction processing part 12 as the log data and stores it into a log work area 15. A log data write-out part 16 writes out the log data stored in the work area 15 to a log storage area 19. A log data retrieval part 18 retrieves the log data stored in the work area 15 or in the storage area 19. Namely, according to the request of a transaction processing part or the like, the retrieval can be executed any time. Thus, the insertion of the data is processed only by possessing the log data.

Title: Fuel injection nozzle for internal combustion engine
Inventor: HASEGAWA TAKAO
IPC: F02M65/00
Filed: 1987-05-19
Abstract: PURPOSE:To damp residual vibration in a short time to improve a detecting function for injection start time by forming the sensor element parts of a piezoelectric sensor of piezoelectric material having the low modulus of elasticity. CONSTITUTION:In a fuel injection nozzle, one end of a nozzle spring 7 to press a needle valve is provided with a piezoelectric sensor 9 to generate an output signal when the needle valve lifts. The sensor element parts 14a, 14b of the piezoelectric sensor 9 are formed of piezoelectric material having the low modulus of elasticity. The residual vibrations of the piezoelectric sensor 9 itself and the nozzle spring 7 are therefore absorbed. Thus the generation of residual signal among the output signals can be controlled, and moreover injection start time can be exactly detected.

Filed: 1982-07-15
Abstract: PURPOSE:To regulate the falling down and chemical erosion of refractory and to achieve the safety long life of furnace wall, by combining the stave-cooling system on the outside of furnace side into the lateral rectangular cooling board connection system. CONSTITUTION:A cooling board 11 is made from cast iron, etc., of which the inside is, in a casting manner, arranged with a cooling tube 12, situated at almost central part of furnace wall thickness, each cooling board being surrounded in circumferential direction of furnace body by lateral connection, and such ring shape boards 11 are, by a suitable interval, arranged in direction of height. Longitudinal row cooling staves 16 are, by a suitable interval, arranged in circumferential direction of furnace body near peripheral shell 17 of this cooling zone on the inside of furnace side and they construct the cooling zone on the outside of furnace side. This two layers cooling zone is constructed by working unshaped refractories 14, etc. in surroundings of the stave 16 and board 11 fixed to the shelf 17. Thus, the refractory 14 is wholly cooled and strongly held with the board 11, and its falling down can be protected by reducing its wearing. Even though the board 11 is exposed after several years operation, the cooling zone on shelf side is in a good condition and the shell is not heated at a high temperature.

Title: Logic circuit
Inventor: TOGASHI MINORU
IPC: H03K19/0185
Filed: 1987-05-19
Abstract: PURPOSE:To realize a high speed logic circuit by connecting a capacitive element to a gate of a constant current source FET used for a driver circuit. CONSTITUTION:A signal generated at a terminal T1 in two current input terminals T1, T2 of a switching circuit 1 is fed from an output terminal O0 to a gate of a FETQS1 of the 2nd part circuit. An inverting signal generated from the terminal T2 is fed to a gate of a FET constant current source QC1 via a capacitor CC1 from an output terminal 0'0. For example, in case of a time tLH, when the level of output terminals O0, O1, O2, O3 changes from a low level (L) to a high level (H), if the capacitive load CL1 exists in the terminal O1, the inverted output goes from H to L, and the gate potential V3 of the FETQC1 goes to a lower potential than that of the steady-state as the result of capacitive coupling. On the other hand, while the potential V1 changes from H to L, the gate potential V3 reaches higher than the steady state. In the transient state, the drain-source current of the FETQC1 is increased/ decreased from the current at the steady state.

Abstract: PURPOSE:To uniformize a flange side distance throughout a whole periphery and to prevent the occurrence of running aground and the drop of a cable by calculating a deviation between adjoining flange side distances measured at measuring points of a preceding winding, and effecting fuzzy control of a winding correcting means depending upon whether a calculating result is higher or lower than a set reference value. CONSTITUTION:Flange side distances D1, D2... between measuring points N1, N2..., set at intervals of a specified distance throughout the whole peripheral surface of a preceding winding, of the edge part of a cable 6 and a flange part 1a toward which winding is about to progress are measured one by one. From data of the flange side distances D1, D2..., a deviation between the flange side distances of adjoining measuring points is computed one by one. Based on deviations DELTAn1, DELTAn2..., winding scheduled points C1, C2,... are computed and set one by one so that a flange side distance of each measuring point of the subsequent winding of the cable 6 is uniformized, and the winding locus of the winding scheduled points of a subsequent winding is decided. The magnitude of the operation speed and an operation amount of a winding correcting means for the cable 6 is regulated depending upon whether a value between a decided winding scheduled point position and a subsequent winding scheduled point exceeds a predetermined reference value S.

Filed: 1987-05-20
Abstract: PURPOSE:To decode an original packet through error correction even if a sent packet string is aborted due to an error during the transmission by extracting a specific bit number from each packet string and constituting the other packet string through interleaving. CONSTITUTION:A random error correction code addition circuit 3 feeds a random error correction code to consecutive information including a video signal, and a packet frame composition circuit 4 forms a packet so that a block comprising the consecutive information including the video signal and a random error correction code has a packet length. Then an interleave conversion circuit 5 extracts the information one by one bit from each consecutive packet, applies interleave conversion and supplies a transmission order number to the packet information to be sent. Thus, even if the abort of packet is caused in the network, since the sequence number is fitted to the information, it is clarified that the packet is aborted at the reception side, and the video signal can be decoded.
