Title: Decelerating energy recovering device in vehicle
Inventor: TAKEDA NOBUAKI
IPC: B60K25/00
Filed: 1985-01-30
Abstract: PURPOSE:To control the rotational efficiency of a variable displacement pump/motor so that the rotational efficiency become maximum, the pump/motor converting decelerating energy into oil pressure which is then converted into starting energy upon starting, by controlling the tilt angle of the variable displacement displacement type pump/ motor in accordance with the stroke of an accelerator pedal. CONSTITUTION:When a brake pedal 53 is depressed upon braking, the rotation of wheels is transmitted, in response to a control signal from a control device 67, to a variable displacement type pump/motor 16 through a propeller shaft 12, a main shaft PTO gear 6, a drive gear 7, a PTO output shaft 8 and an electromagnetic clutch 14. Pressure oil generated from the motor 16 is charged in an accumulator 41 through a hydraulic passage 40. Upon starting, when an accelerator pedal 51 is depressed, a valve 81 is opened in response to a control signal from the control device 67 so that the pressure oil is fed to the pump/motor 16 from the accumulator 41. The torque of the motor 16 is transmitted to the wheels through the transmission system which is reverse to that upon braking. At this time the tilt angle of the motor 16 is controlled in accordance with the stroke of an accelerator pedal 51, thereby it is possible to rotate the motor 16 with a maximum degree of efficiency.

Abstract: PURPOSE:To realize slow start or slow stop of a motor by arranging a switching element to be subjected to pulse width modulation and an analog circuit for producing a motor control output signal and feeding the motor output control signal to a speed feedback circuit. CONSTITUTION:When a stop signal P has a level L and a start signal T has a level H, a transistor 11 is turned OFF.

Motor output signal VOUT does not vary when the pulse width modulation signal Q has the level L. When the start signal T is brought to the level L and the stop signal P is brought to the level H, Tr 16 is turned OFF. Consequently, a pulse width modulation signal Q which is brought to the level H only when the speed command voltage division signal VIN exceeds over the triangular wave signal S is obtained and the C20 is charged during the level H interval. The motor output signal VOUT does not vary when the pulse width modulation signal Q has the level L.

Title: Method and device for shared memory access control
Inventor: HIRAMATSU KIMIMASA
IPC: G06F12/06
Filed: 1990-01-26
Abstract: PURPOSE:To map the memory space of a shared memory in the address space of a higher-order processor by combining the address, which the memory access request from the higher-order processor designates, with second mapping information at the time when this address is within the area discriminated with first mapping information. CONSTITUTION:First mapping information which discriminates a certain area in the address space and second mapping information which discriminates the position of a desired area in the space of a shared memory 22 mapped there are sent from a second processor 1 to an access controller, and the access controller receives and holds both mapping information. The access controller discriminates whether the address designated by the access request from the second processor 1 to the memory 22 is within the area discriminated with first mapping information or not, and second mapping information is combined with the address designated by the access request in response to this discrimination to execute the access request. Thus, a part or the whole of the memory space of the shared memory 22 is mapped in the address space of a higher-order processor 1.

Title: Feed pump control system
Inventor: KAWAMURA NOBUYUKI
IPC: F04B49/06
Filed: 1979-02-14
Abstract: PURPOSE: To prevent flushing phenomenon into a feed pump at low pressure in feed command by keeping rate of feed water flow during operation larger than a limit value of that of circulating water at all times.  
     CONSTITUTION: When rate of feed water flow decreases according to a command signal from load demand for some reason or other during operation of a pump P, and thus an output of PI operator 14 becomes greater than the command signal from load demand, a signal from the PI operator 14 turns to a feed water command signal 100a to a flow control valve FV. The rate of feed water flow during operation can consequently be kept larger at all times than the limit value of that of circulating water to secure a minimum rate of flow of the feed pump command, thereby preventing flushing phenomenon into the feed pump at low pressures in feed command.

Title: Duplex output selecting device
Inventor: MAKINO TERUYUKI
IPC: G05B9/03
Filed: 1989-01-26
Abstract: PURPOSE:To prevent the occurrence of the output down to any type of a single trouble by outputting directly the output of a duplex controller to a control subject when a duplex output selecting device has its own trouble and then outputting the current value recorded to an analog memory to the control subject when one of two devices contained in the duplex controller has a trouble. CONSTITUTION:When the outputs of current converters 8 and 9 are not coincident with each other, an output relay 12L of a discordance detector 12 is energized and an analog memory 14 holds the voltage of the same level of the output Vc of a switch 16. Then a current converter 15 outputs a current I to a control subject 5 via switches 16 and 17 so as to secure the output voltage Vc. Thus a current is successively outputted to the subject 5 at discordance. The detector 12 can detect the discordance at a high speed by using a TTLIC at a detecting part. At the same time, the count value of the memory 14 is also instantaneously fixed. The output, however, is once interrupted at switch of the relay. Then the response time of a plant is extremely long compared with the working time of the relay. Thus the influence of the relay switching time can be neglected to the plant.

Title: Sense circuit
Inventor: TAKEDA TAKASHI
IPC: G11C11/34
Filed: 1983-02-03
Abstract: PURPOSE:To suppress an increase in the chip area of an integrated circuit by adding a gate and allowing a sense circuit part itself to function to latch data at read operation. CONSTITUTION:When an RAM is read, one FF of a cell part is connected to signal lines 9 and 10 through gates. When the FF is set to ''1'', the signal line 9 is at a high potential and the signal line 10 is at a low potential. At this time, when a write signal phiR is set to ''1'', the output of 11 is ''1'' and the output of 12 is ''0''. One input to 13 is ''1'', so its otput is ''0'', so that the output of 14, i.e. the output of the ram is ''1''. On the other hand, when the FF connected to the signal lines 9 and 10 is set to ''0'', the signal line 9 is at the low potential and the line 10 is at the high potential. At this time, when the signal phiR is set to ''1'', the output of 11 is ''0'' and the output of 12 is ''1'', so that the output of the RAM is ''0''. When data is written in the RAM, the signal phiR is set to ''0''. Therefore, the outputs of 11 and 12 are both ''0'' regardless of the states of the signal lines 9 and 10, but the read data of the RAM is held at the output of 14.
