Title: Power source for arc welding
Inventor: IWATA AKIHIKO
IPC: B23K9/06
Filed: 1985-03-25
Abstract: PURPOSE:To stabilize welding and to prevent an inverter from breaking by installing setting circuits for setting the 1st and 2nd aimed values of welding current as well as disposing a rapid-response current-control circuit for controlling an inverter. CONSTITUTION:A setting circuit 11 for setting the 1st aimed value V1 of welding current and a setting circuit 12 for setting the 2nd aimed value in rapid response to a sudden load change, are disposed respectively. Further, a rapid-response current control circuit 13 for transmitting a drive signal to an inverter 3 by inputting the 2nd current aimed value V2 of circuit 12 and an output of a PWM circuit 9. When a welding current exceeds the 1st aimed value V1 and rises by the delay of response of a PID circuit 10, the circuit 13 acts rapidly to clip the current to the 2nd aimed value V2. Thereafter, the circuit 10 responds to keep the welding current at the 1st aimed value V1. Accordingly, the welding is stabilized and the breakage of inverter 3 is prevented.

Title: Electric motor
Inventor: MAIKERU EI PIERA
IPC: H02K7/10
Filed: 1990-03-09
Abstract: PURPOSE: To obtain a high torque output with a low speed without using the high revolution member of an electric motor, by a method wherein a deceleration mechanism is formed on a part where the stator and rotor of the motor are unified. CONSTITUTION: Two stator rings 20a and 20b which move on a track without rotation are provided with 180 degrees difference between each other around a rotor 145 having a predetermined number of lobes 16. Each ring has rollers 22 more than the lobes 16 by one. That is, in the case of a system with 12 rollers, the reduction gear ratio is 1:11. Windings 36a-36h are so provided as to face each other as poles. The stator ring moves as a magnetic force, i.e., an electric impulse, induced by the winding is successively moved around the facing poles. As a result, the rotor rotates at a speed which is obtained by dividing the speed of the stator ring by the built-in reduction gear ratio. As the two stator rings are respectively moved on the tracks shifted from each other by 180 degrees, the mass on the track and the torque of the rotor can be balanced.

Abstract: PURPOSE:To reduce a memory area by encoding a single word of high use frequency, storing in the memory, automatically retrieving a code table when registering the name of a good by means of an electronic balance and changing a good's name character code to a single word code. CONSTITUTION:When the signal word of the highest using frequency of the goods name registered words is encoded, stored and the goods name is registered by the electronic balance, this code table is automatically searched and stored in the memory by the single word code. When the goods name is registered by a single word code table formation device, if an operator presses a prescribed key in a keyboard after the completion of registering the goods names of all the goods, this device searches the single word of high using frequency. As a result of this, the goods names of the high using frequency are gathered in order, and the single word code table of, for instance, three digits (in the case of 'BEEF', 100) is formed. By using the encoded single word code table, for instance, an area requiring 8 digits in the case of 'BEEF' in the registering area of the electronic balance may required only three digits.

Abstract: PROBLEM TO BE SOLVED: To prevent a harmful influence caused by breakage overturn and movement, by converting the vibrational energy of an earthquake into kinetic energy for moving an image forming device. SOLUTION: Respective mats 8 and 9 are arranged in specific positions on both sides in the longitudinal and lateral directions, to which a printer 1 can be moved, and a framing member 10 and a floor driven member 11 are incorporated in the mats 8 and 9. The framing member 10 and the floor-driven member 11, which are in the mat 9 can be connected to the mat 8 and incorporated after the printer 1 is put in the mat 8. The printer 1 and the mats 8 and 9 are kept at a fixed distance and even if the printer 1 is moved because of the earthquake, its energy is absorbed so that the printer 1 is stopped, because it is surrounded by the respective mats 8 and 9. The respective mats 8 and 9 are provided with the framing member 10 and the floor driven member 11, not to be moved.  Thus, even if the printer 1 placed on a 2000-sheet feeding deck 4 is moved because of the energy of the earthquake, the moving amount can be regulated within a prescribed dimension, so that the occurrence of a failure in blocking an evacuation route, etc., can be prevented.
