Title: Butt welding method
Inventor: KO TAKAO
IPC: B23K11/02
Filed: 1987-02-04
Abstract: PURPOSE:To improve the weld quality extending over the entire widths of sheet steels by butt-welding the sheet steels while preventing clearances from taking place on both sides of the end faces of the sheet steels at the time of performing the welding. CONSTITUTION:At the time of joining the sheet steels 2 and 2 by the butt-welding via electrodes 1 and 1, projection parts 4 are provided at both side parts of the steel end faces where the clearances take place in advance. At this time, the width (l) of the projection parts 4 and the projection lengths D at the time of butting the end faces are set to about 1-50mm and >=0.01mm respectively to perform the welding. In this way, since an electric current can be allowed to flow excessively to a place where the heat input is insufficient at a first stage of welding, the insufficient heat input at both the side parts of the steel end faces is dissolved and the excessive heat input at the position close to the inside slightly from both the side parts of the end faces can be prevented. At the time of welding, since the welding is performed while preventing the clearances taking place on both the side parts of the sheet steel end faces, the defective joining due to the unevenness of the heat input is prevented and the weld quality is improved extending over the entire widths of the sheet steels.

Title: Water reducing agent of concrete
Inventor: HAMADA SHINJI
IPC: D21C11/02
Filed: 1992-01-16
Abstract: PURPOSE:To obtain an AE water reducing agent capable of readily supplying proper air entraining properties by specifying a lignin sulfonate content of waste liquor of sulfite pulp as an AE water reducing agent. CONSTITUTION:This water reducing agent of concrete consists essentially of waste liquor of sulfite pulp having <=45% lignin sulfonate content. Since content of lignin sulfonate mainly providing air entraining properties is regulated, the water reducing agent has low air entraining properties and enables slight change of fluidity of concrete with time. The water reducing agent has low content of lignin sulfonate but does not drop water reducing properties with increase in content of denatured substance of saccharide having more water reducing properties than the lignin sulfonate. The waste liquor of sulfite pulp having <=45% lignin sulfonate content is obtained by removing a high molecular weight region from the waste liquor of sulfite pulp by an ultrafilter or a permeable membrane.

Title: Fixing device and image forming device
Inventor: INAZAKI YUTAKA
IPC: G03G15/20
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent a fixing failure and an excessive temperature rise and to realize low power-consumption. SOLUTION: When printing on recording paper starts, the temperature of a fixing roller before it is heated is measured, and a different process is performed depending on whether this temperature belongs to a first temperature- range or a second temperature-range. For example, in the case of the first temperature-range, the rate of a temperature rise is calculated, and the timing of the start of the printing is determined according to the result of the calculation. In the case of the second temperature-range, on the other hand, time to start the printing is determined according to the temperature of the fixing roller 1 measured before it is heated, and a proper process is performed according to whether the size of the recording paper is small or not. In these processes, each control temperature is decreased according to the number of prints being processed.  This prevents a fixing failure and an excessive temperature rise and also realizes low power-consumption.

Title: Acceleration/deceleration control for motor
Inventor: YOSHIHARA MUNESUKE
IPC: H02P7/00
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To control voltage instability caused by a delayed magnetic flux change of a motor during acceleration/deceleration in a constant power range, by supplying field current for a target rotational speed from the time of control start, thereby conducting acceleration/deceleration control. SOLUTION: When rotational speed is increased from '0' to target rotational speed Nm, field current I dm for target rotational speed Nm is supplied to a motor from the time of control start of rotational speed of '0', and controlled at constant conditions. When the rotational speed is increased from N1 to the target rotational speed Nm in a constant power range, the field current I dm for the target engine speed Nm is supplied to the motor from the time of control start, and controlled at constant conditions.

Title: Tension controller
Inventor: OOTA OKIYOSHI
IPC: G11B15/43
Filed: 1989-02-03
Abstract: PURPOSE:To execute the tension control irrespective of the speed of a tape and its winding thickness by providing a filter means for filtering an output of a rotation detecting means of a reel, and a reel driving means for applying the torque being proportional to its output to the reel. CONSTITUTION:At the time of holding a tension value applied to a tape 1 constant, it will suffice that the torque being proportional to a radius of a reel 3 containing the tape winding thickness is applied to the reel 3. A rotating state of the reel 3 is converted to rotational information through a rotation detecting means 4. The tape 1 is driven at a constant speed by a tape driving means 2, therefore, from an output of the means 4, information related to the radius of the reel 3 is obtained. By a filter means 5, information being proportional to the radius of the reel 3 is outputted from the output of the means 4, and converted to the torque by a reel driving means 6. Since this torque is proportional to the radius of the reel 3, tension applied to the tape 1 becomes constant irrespective of the radius of the reel 3.

Title: Manufacture of inductor element and its fitting method
Inventor: TOTSUKA SATOSHI
IPC: H01F41/06
Filed: 1990-02-06
Abstract: PURPOSE:To stabilize the mounting onto an electrode land, by flatly forming the end portion of a coil main body, simultaneously eliminating a covering part, dipping the end portion in a low temperature melting solder vessel, and finishing soldering. CONSTITUTION:The tips of terminal parts 3, i.e., the start-of-winding and the end-of-winding, of a coil main body 1 are bent so as to be parallel to the winding axis direction, and a flat part 4 is formed by mechanical pressing. At the time of pressing, a coating film at this part is broken into pieces and removed from the terminal parts 3. As a result it is unnecessitated to eliminate a coating part by heating it at a high temperature, so that the end portion 3 can be completely soldered only by dipping it in a low temperature melting solder vessel. Hence the coil main body can be stably retained on an electrode lands 7, and the temperature of the solder vessel can be decreased, so that oxidation is slow and further the temperature management is simplified. Thereby the stable mounting onto an electrode land is enabled.
