Title: Method for controlling vehicle driven by electric motor
Inventor: OOTA HIROKI
IPC: B60L15/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To improve fine operability of a vehicle driven by an electric motor. SOLUTION: A control circuit 21 detects the step-down angles of an accelerator 2, a brake pedal 3 and in inching pedal 11 from the outputs of step-down angle sensors 12 to 14. The inching pedal 11 is mechanically interlocked with the brake pedal 3, which, therefore, is stepped down simultaneously when the inching pedal 11 is stepped down. The control circuit 21 gives an instruction to a power converting circuit 22 to turn down the driving force, which is to be generated by stepping down the accelerator 2, of a vehicle drive motor 4 according to the stepped down angles of the inching pedal 11. The power converting circuit 22 supplies power to the drive motor 4 in accordance with the instruction from the control circuit 21.

Title: Drum speed control device for drum shear
Inventor: UNO TAKUJI
IPC: B23D36/00
Filed: 1987-02-25
Abstract: PURPOSE:To prevent the speed of a motor for driving a drum shear from varying by detecting the rotary angle of the drum shear by means of both a rotation detector and a counter, and outputting a compensation signal for compensating the rotary speed variance by means of a compensation circuit. CONSTITUTION:The rotary angle of a drum shear is detected with a counter 24 to which a signal 10 from a rotation detector is inputted. The rotary speed of a motor is controlled by computing a compensation signal 25 so that the rotary angle is accelerated from 0 deg.-180 deg. and decelerated from 180 deg.-360 deg. for a short material and reversing the order for a long material to compensate the speed variance by means of a compensation circuit 26. A torque compensation value at the time of the maximum speed with a maximum or minimum cutting length at which the speed variance is the greatest is obtained from actual measurements. A factor K1 is determined so that the compensation value becomes zero when the cutting length L0 is equal to the drum periphery length. Factors K2 and K3 which are proportional to the primary and secondary speeds of line speeds v are determined to compensate such that the compensation amount increases with the increase in the speed and as a result the speed variance becomes small even at the time of acceleration during a buildup operation of a line.

IPC: H02P8/14
Filed: 1981-03-25
Abstract: PURPOSE:To keep freedom in setting drive pulse time intervals at increase and decrease of a speed, by storing drive pulse time interval data to determine rpm in a memory, and controlling a speed based upon them. CONSTITUTION:Drive pulse time interval data are stored in a memory 32 to determine rpm of a pulse motor 35. The memory 32 is connected to a timer 33 or programmable counter. A control circuit 31 supplied the memory 32 with an address designation signal (b) and a memory control signal (c) everytime the timer 33 pulse is input. At the same time, it outputs a preset signal (g), updating preset input of the timer 33. This action continues until the pulse reaches the preset number. The pulse motor 35 is driven via a drive circuit 34. Therefore, a preset value can be updated by the memory change. This establishes speed variations easily in correspondence with loads 36.

Abstract: PURPOSE:To make it possible to freely adjust the temperature of the titled KOTATSU (foot warmer) by providing the electric foot warmer with an external temperature adjustor clearly indicating a calorific value without interrupting a current within a practical temperature range. CONSTITUTION:The operational point of a temperature switch 3 is fixed so as to operate the titled foot warmer at a position of ''strong'' in the temperature scale of the ordinary foot warmer.

The output terminal of the chalk coil 7 of a temperature adjuster 6 installed at the intermediate of a power source cord 5 is changed over by a rotary switch 8, and the current is limited so that the calorific value becomes 7W...10W...13W...16W...20W. At the time of the continuous calorific value of 20W, a radiation area in which the radiation quantity balances, is required. As a result of the experiment, it has been found that it is sufficient if the size of a height of 24cm and a length of 30cm. The temperature switch 3 operates only when the radiation quantity reaches more than 20W to interrupt the current and retains a predetermined calorific value.
