Title: Non-volatile semiconductor memory
Inventor: TERADA YASUSHI
IPC: G11C17/00
Filed: 1988-02-12
Abstract: PURPOSE:To correct an error by an error correcting code (ECC) even when a defect occurs in a word line as the output line of a row decoder by dividing the word line into plural word lines and providing high voltage switches the boost the respective divided word lines at the time of writing for the respective word lines. CONSTITUTION:A memory array is divided into two by a row decoder 4, and the respective divided word lines are further divided into six by a word line driver 16. Namely, the memory array is divided into twelves as a whole. The driver 16 is composed of two inverters and high voltage switches 7 connected to the output of the inverters. When a breakdown occurs in the gate oxide film of the selective transistor of a memory cell, though a divided word line 2a, to which the memory cell belongs, is not boosted due to a leak in a part where the breakdown occurs, the potential of the word line 2a rises up to a degree equivalent to supply voltage, and another divided word line 2a in a next block is boosted by the switches 7. Thus, the error can be corrected by the ECC even when the defect occurs in the word line.

Title: Communication controller and storage medium
Inventor: KANEMURA TOSHIAKI
IPC: H04L12/701
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of repeating data communication from the beginning at the time of a restart even when data communication is interrupted by passing through a communication disabled area where radio waves do not reach during data communication by radio. SOLUTION: At the time of travel by a transportation means such as a train, a CPU 2 judges the means and a travelling route based on present position data and map information, etc., selects data on communication disabled area present on the shortest travelling route from a present position from the data base of communication disabled areas and calculates a required arrival time.  Then, in the middle of data communication by radio, the CPU 2 stores communication information required for restoring a communication state at the time and interrupts the data communication in the case that the required arrival time is less than a prescribed time, and in the case that a communication disabled area is passed through to reach a data communication available area, reads the communication information, restarts the data communication and performs control so as to restore the communication state before interruption.

Title: Flow deflecting device
Inventor: SUGAWARA NORIO
IPC: F24F13/10
Filed: 1987-02-13
Abstract: PURPOSE:To permit the deflection of flow into a proper direction in accordance with the condition of installation or the configuration of a room, by a method wherein the position of a nozzle is deviated from the axis of a flow passageway and the configuration of a guiding wall is formed so as to be asymmetric with respect to the axis of the flow passageway. CONSTITUTION:A nozzle 9, having a choked area 11 from the whole circumference, is provided so that the axis 10 of the nozzle is eccentric with respect to the axis 8 of a flow passageway. The size of a guiding wall 12 is asymmetric and an angle betabetween the tangential line of the downstream end of the wall 12 and the axis 8 of the flow passageway is formed so as to be changed depending on a direction. A part of flow, entering the flow passage-way 7, forms bias flows Fa, Fb by the choke 11. The flow Fa is intercepted by an intercepting plate 13 and the flow Fob, flows out of the nozzle 9, is deflected upwardly by the bias effect of the flow Fb. The tangential angle beta1 of the upward deflection is formed so as to be small in the presence of a ceiling 15. The intercepting plate is turned to an opposite direction to deflect the flow downwardly. In this case the bias flow Fa becomes large by the eccentricity of the nozzle 9 with respect to the axis 8 of the flow passageway of the nozzle 9 and the tangential angle beta2 is also large, therefore, the blow-off flow Fob is deflected downward considerably.

IPC: F04B49/10
Filed: 1992-02-19
Abstract: PURPOSE:To perform fail safe by keeping the loss of hydraulic energy and heat generation down at the fail safe time of a pump failure in the hydraulic system whose hydraulic supply source is a variable displacement pump. CONSTITUTION:A fail safe valve 12 is provided in a pump suction oil passage 19. The valve 12 comprises a poppet valve 13, spring 14 throttle 15, and stopper 16, for example. While a variable displacement pump 11 is normally operated, the poppet valve 13 keeps its suction oil passage opened. When system supply pressure rises abnormally due to the breakdown of the pump 11, the poppet valve 13 is moved so as to close the suction oil passage and becomes pressed to the stopper 16 at the position of the stopper 16 due to the pressure difference between those before and after the poppet valve 13 resulting in the close of the suction oil passage. The flow rate is throttled, the pressure of the downstream of the throttle 15 becoming negative. The pump discharge rate and discharge pressure are lowered to near 0. The amount of the energy loss and heat generation become minute.
