Title: Timer device
Inventor: TAKASHIBA YOSHIYASU
IPC: H01H43/02
Filed: 1990-02-13
Abstract: PURPOSE:To set timer time highly accurately by attaching a display means, which instructs timer graduation in accord with the selection of a driving mode, to a console panel. CONSTITUTION:When desired timer time is set by operating a timer range changeover switch 84 and winding up an operation shaft 12, a controller 41 selects the driving mode designated by the switch, so the driving speed of a driving means 29 is limited based on this mode, and it is rotated in the direction reverse to the winding-up direction of the operation shaft 12. Specified driving speed of the driving means 29 is maintained until the timer is turned off. Nevertheless, the timer sendings by each driving mode of the controller 41 are executed at different speeds. The controller 41 actuates display means 85-87 at the time of winding up of the timer shaft, so by this means some one timer graduation is instructed, therefore since the winding up of the operation shaft 12 can be done based on this instruction, the index part of a timer knob 40 can be set to a proper timer graduation.

SOLUTION: Since an angle member 46 is arranged in a vertical direction and a protrusion contact part 46b is protruded in a right angled direction from contact surfaces 28c and 28c, a horizontally sliding door 28 is hardly warped. Further, the protrusion contact part 46b is brought into contact with a door stopper surface 12a of a hodate 12, and since tip surfaces 28e and 28e of the horizontally sliding door 28 is brought into contact with a bottom 30a of a door rebate 30, even when a warp occurs to the horizontally sliding door 28, adhesion is not damaged. Further, since the contact surface 28c is oblique to a traffic line M of the horizontally sliding door 28, when the horizontally sliding door 28 is closed, a component wherein the contact surface 18c is moved to a door step E is produced.  As a result, the whole of the horizontally sliding door 28 can be adhered to magnetic attraction packings 32 and 32, the interior of a room is completely closed, and leakage of a sound is prevented from occurring.

IPC: H02P7/292
Filed: 1982-02-26
Abstract: PURPOSE:To prevent a motor from accelerating after recovery by controlling by isolating an outer loop control system which corrects the speed to the variation in the offset when a load current variation rate or a speed variation rate exceeds the allowable value to the instantaneous variation in the speed of the motor. CONSTITUTION:A power source 1 drives a motor 3 through a power converter 2. A pulse generator 4 detects the speed of the motor 3, and applied it through a frequency/voltage converter 5 to a comparator 6. The comparator 6 compares it with the output of a reference speed setter 7, and forms a minor loop control system which controls the motor 3 through a speed controller 8. A frequency comparator 9 compares the frequencies from the generator 4 and the setter 7, applies it through a contact 19A to the comparator 6 to form an outer loop control system. The detection signal of a load current detecting current transformer 15 is inputted through a differentiator 16 to a load current abnormal variation detector 18, and operates a timer 19 when the load current variation rate  exceeds the allowable value of the setter 17, thereby opening the contact 19 A  for the prescribed time. Accordingly, it can prevent the speed of the motor once  recovered from accelerating.

Title: Current control circuit
Inventor: KANEKO HIROMI
IPC: G05F1/10
Filed: 1987-02-12
Abstract: PURPOSE:To avoid the consumption of electric power as well as the generation of heat and noises by forming a current control circuit with use of a D/A converter and a constant current control circuit so that the current value can be varied dynamically by a program. CONSTITUTION:When a control signal 6 of a certain level is applied to a D/A converter 2, the reference voltage signal 7 corresponding to the signal 6 is applied to a constant current control circuit 3. The circuit 3 delivers a driver control signal 8 so that the signal 7 has the same level as that of a current detecting signal 9. A driver circuit 4 drives a motor 5 based on the signal 8 and detects the value of the current flowed to the motor 5 for output of the signal 9. Thus the current flowing to the motor 5 can be changed with change of the value of the signal 6 received from the microprocessor 1. Thus the signal 6 of the converter 2 is controlled by a program and therefore the current flowing to the motor 5 is freely changed.
