Title: Motor controller for vehicle
Inventor: TAKAHASHI KAZUYA
IPC: H02P27/04
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a motor controller for controlling a motor without deterioration in steering caused by a difference in revolution speed at turning of the vehicle with respect to an electric vehicle with the induction motors connected to right and left driving wheels and driving the induction motor with a common inverter. SOLUTION: When a vehicle is turned by driving force, a revolution speed difference ΔNs between revolution speed Nin of an induction motor of an inner wheel and revolution speed Nout of an induction motor of an outer wheel is calculated. A control curve is determined by the revolution speed difference ΔNs and output torque T. A primary current according to the control curve is determined, and a sliding speed Ns0 is calculated from the control curve. A driving current revolution speed NI is calculated from the sliding speed Ns0 and the revolution speed Nout. The induction motor is put under sliding-speed control at the driving current revolution speed NI and a primary current value I as a controlling target, the same torque as the outer wheel is generated in the inner wheel, and a deterioration in steering can be prevented.

Abstract: PURPOSE:To facilitate winding work, in a method for preparing a liquid absorbing roll used in the removal of the liquid on the surface of a printed circuit board, by inserting the pin bodies protruding from the outer peripheral surface of a hollow core roll in the mounting holes piercing a liquid absorbing sheet to wind said sheet around the roll. CONSTITUTION:The pin bodies 6 producing from the outer peripheral surface of a hollow core roll 3 are inserted in the mounting holes 5 piercing a liquid absorbing sheet 4 to wind the sheet 4 around the roll 3. At this time, since each liquid absorbing sheet 4 is cut to winding length going round the roll 3 and a plurality of the mounting holes 5 pierce the sheet 4 at predetermined positions, the pin bodies 6 are successively inserted in the mounting holes 5 to wind the sheet 4 around the roll 3. Since the pin bodies 6 and the mounting holes 5 are bonded by applying a urethane or epoxy type adhesive to the places where the pin bodies 6 are inserted, the adhesive can rapidly be applied in the necessary min. amount in the optimum state. After the liquid absorbing sheets 4 are wound in a multiple state, the adhesive is applied to both ends of the sheets 4 in the axial direction to seal both end surfaces of the sheets 4.

Filed: 1982-11-12
Abstract: PURPOSE:To avoid useless access of a central processor to a main storage device by informing the end of data transfer to the central processor at a time point when the data stored temporarily in a data buffer in a main storage controller are all transferred to the main storage device. CONSTITUTION:A channel device 6 transfers data to a main storage device 2 as well as an I/O device (not shown in the diagram) connected to the device 6 by a command of a central processor 1. In this case, a data buffer 4 is provided to a main storage device 3 to store the data temporarily in the buffer 4. The data is transferred independently between a channel 5 and the buffer 4 as well as between the buffer 4 and the device 2. Thus the buffer 4 is used effectively. At the same time, the end of data transfer with the channel needed by the device 2 is informed to the processor 1 from the buffer 4. After receiving this information, the processor 1 gives access to the device 2. In such a way, useless access is prevented and the workability is improved.

Title: Semiconductor memory
Inventor: SAWADA SEIJI
IPC: H03K19/0185
Filed: 1990-07-26
Abstract: PURPOSE:To shorten access time by connecting the source of an N-ch L data output transistor (Tr) in the final step of an output buffer circuit to a negative voltage. CONSTITUTION:When an input signal A2 is turned from L to H, an input signal A3 of an N-ch L data output Tr 3 in the final step connecting the source to a negative voltage 6 and connecting the drain to an output terminal 7 is turned from L to H, and the output is turned from a high impedance state to a negative potential. Afterwards, an input signal A1 of an N-ch L data output Tr 2 is turned from L to H and the L data output Tr 2 is turned ON. Since the input signal A3 of the L data output Tr 3 is returned from H to L, the L data output Tr 3 is turned OFF and the output is turned from the negative potential to 0V. Thus, even when ringing is generated, potential difference between a ringing level and a VOL level can be enlarged, and access time can be shortened.

In a thermocouple type infrared detecting element 9' formed in this way, no dead zone is present in the series direction of the temperature sensitive bonded parts 5. Sensitivity is lowered only to about 1/2. The pitch 1/2 the pitch at the temperature sensitive bonded parts. Therefore, the sensitivity uniformity in the series direction of the arrangement is improved to a large extent.
