Patent JP-H04131248-A (JP)
Title: Ink jet recorder
Inventor: KINOSHITA HIROYUKI
IPC: B41J2/18
Filed: 1990-09-22
Abstract: PURPOSE:To stabilize the action of a pump by a method wherein the pump is provided with a guide member for guiding a piston, and a half or more of the length from a top surface in the pump to the upper dead point of a power transmitting part for transmitting a power to the piston is covered with the guide member. CONSTITUTION:A piston 16 is provided with an O-ring 18 and a pump ring 19. A cylinder 17 is provided with ribs 20a, 20b as a guide for the piston 16 on a part other than a sliding part of the O-ring 18. When a pump cam 14 is rotated, a force is applied to the piston 16 not only in a Y-axis direction but also in an X-axis direction. The occurrence of the sticking of ink in the pump results in the cylinder 17, the O-ring 18, and the pump ring 19 coming into a sticked state. At this time, if the pump cam 14 is rotated, a large resistance occurs in a Y-axis direction, and a large force is also applied in an X-axis direction. However, even in this condition, the ribs 20a, 20b ensure the normal action of the piston 16. In this manner, a recovery action can be normally conducted.

Title: Detecting device of torque
Inventor: KAWAMATA SHOICHI
IPC: G01L3/10
Filed: 1987-10-09
Abstract: PURPOSE:To detect a torque from the time of stop to the time of high speed, by obtaining triangular wave outputs from magnetoresistance effect elements disposed opposite to magnetic rotary encoders which are provided on the drive side and the load side of a rotating shaft, and by detecting an angular difference between said outputs. CONSTITUTION:Drums 2 and 2' having N and S poles 3 and 3' recorded thereon are provided on a rotating shaft 1 at a prescribed gap between them, and sensors 4 and 4' consisting of magnetoresistance effect (MR) elements R1 and R2 are disposed opposite to these drums at a small gap therefrom. The MR elements R1 and R2 are disposed in separation by lambda/2 from each other when an interval between the N and S poles is lambda. The resistances of the elements R1 and R2 are varied due to changes in intensities of the N and S poles. The shaft 1 is distorted when a torque is applied thereto and causes a phase difference proportional to the torque between outputs due to variations in the resistances of the sensors 4 and 4'. By selecting appropriate gaps between the drums 2, 2' and the sensors 4, 4', on the occasion, the torque is detected as a phase difference between outputs of triangular waves. Since these outputs are not dependent on the speed of rotation, the torque can be detected highly precisely even at the time of stop.

Title: Serial printer
Inventor: SAEKI YOSHIRO
IPC: B41J13/10
Filed: 1987-10-09
Abstract: PURPOSE:To provide clear print by employing a moving guide having side bars which define spacing longer than the carriage of a print head but shorter than the travel of the head and enclose the opposite sides of the carriage. CONSTITUTION:In printing on a recording medium 8 in a predetermined position, a print head moves from the home position to the right, and the medium is firmly pressed against the platen by the head 6 and a side bar 11a so that clear printing is possible. The gap between side bars 11a and 11b of a moving guide 11 is wider than a carriage 5. Therefore, the guide 11 does not follow the movement of the head 6 in the beginning, and the side bar 11a keeps pressing the recording medium 8. On the other hand, the gap between the side bars 11a and 11b is shorter than the travel of the head. When the right-hand edge of the carriage 5 presses the inner face of the side bar 11a, the moving guide 11 follows the carriage.

The optimal amt. of water 4 to be sprayed is about 20-50kg/ton of coal/temp. drop of 100 deg.C of the high-temp. coal. The coal 6 which has been cooled to a suitable temp. is fed into a second cooler 8. Air 9 of room temperature is fed into the second cooler 8 to allow the coal 6 to cool at a final temp. The cooled coal 11 is discharged and transferred to cool at a power station or the like.

Title: Walk control device for leg type mobile robot
Inventor: HASEGAWA TADAAKI
IPC: B25J5/00
Filed: 1992-08-28
Abstract: PURPOSE:To stabilize the high speed walking attitude of a robot by furnishing a means to distribute over the legs the resultant force and moment of all floor reactive forces to be aimed at, and providing a means to control the attitude of the robot in accordance with the distributed floor reaction force. CONSTITUTION:All floor reactive forces acting on a robot as a whole are designed previously and distributed over two legs (flat foot) 22L, 22R from the time the legs are supported so that the floor reactive force is continued. That is, a large spin moment is produced at the supporting leg when separating from the floor, so that the floor reactive force moment balancing with the spin moment is given positively to the leg as the supporting one at the next single leg supporting cycle from the time supporting is made with the two legs in advance, and thereby the floor reactive force moment of legs is made continuous even at the boundary point (at separating from the floor). In other words, control is made so that the floor reactive force moment on each leg varies continuously, so that the floor reactive force moment of the leg does not exceed the friction limit even after separation from the floor, and the stability of the attitude can be surely secured.

Abstract: PURPOSE:To prevent overshoot at the time of supplying hot water and delay of starting at the time of heating to circulate by storing an integral value feedback calculated by dividing to a circulating heating and hot water supplying as optimum integral value, and using it as a calculated value of a feedback calculated value of next time for a predetermined time. CONSTITUTION:A circulating heating judging unit 21 outputs a circulating signal when a water flow rate Q is detected by a water flow rate sensor and a water flow switch is so turned OFF as not to detect a water flow. An optimum integral value controller 29 adds a stored value X at the time of circulating to heat stored in an optimum integral value memory 28 to a feedback calculator 30. On the other hand, at the time of supplying hot water in which the circulating signal is not output, a stored hot water supply value Y is added to the calculator 30. The calculator 30 applies the stored values to a heat quantity deciding unit 43. After a predetermined time is elapsed from the start of controlling, a switch 27 is closed, a deviation of a hot water temperature TM from a set temperature TS is applied to the calculator 30.
