Title: Electric power steering unit
Inventor: TAMAI KATSUNORI
IPC: B62D117/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain the restoring force at the slewing motion, and to judge the slewing angle and the returning quantity, by comprising a means for operating the first and second motor driving signals, and determining the third motor driving signal by comparing the first and second driving signals, for driving a motor. SOLUTION: A steering torque signal added to a steering handle 2 is read, and a chopper ratio D1 of a motor 12 is operated. The chopper ratio D1 is set in such manner that it is agreed with a direction of the steering torque, and is almost proportional to the magnitude of the same. Then the rotation angular speed at the present time, of the fork lift is read, and the chopper ratio D2 of the motor 12 which is determined by this angular speed, is operated. The chopper ratio D2 is set in such manner that the direction is opposite to that of the steering ring, and the chopper ratio D2 is almost proportional to the rotation angular speed. Then the chopper ratios D1 and D2 are added to determine the chopper ratio D3 by which the motor 12 is finally driven. Whereby the restoring force can be obtained, and the judgement on the steering can be performed.

IPC: F25C3/04
Filed: 1990-03-20
Abstract: PURPOSE:To manufacture snow pieces similar to natural snow pieces continuously within a short period of time by a method wherein numberless ice crystals are produced employing an ice crystal producing means including a liquid spraying means and a refrigerating means while the ice crystals are levitated in the sound field of ultrasonic wave. CONSTITUTION:The inside of a refrigerating chamber 3 and especially a collecting chamber 6 are cooled by a refrigerating mechanism 2 while liquid is atomized by a liquid atomizing mechanism 1 to send the misticated liquid into the collecting chamber 6. The mist, sent into the collecting chamber 6, is changed in the collecting chamber 6 into numberless ice crystals, then, the crystals are sent out of a mist guiding chamber 8 together with the mist and dropped naturally, then, the crystals are guided into the sound field of ultrasonic wave of an ultrasonic levitating mechanism 9. In this case, the ice crystals and the mist are coupled by the aggregating effect of ultrasonic wave and become snow pieces 22, then, ambient ice crystals and mist are adhered to the snow pieces 22 whereby the size of the snow pieces 22 is increased. When the snow piece is grown to the degree of several square mm, the weight of the snow piece is increased and the snow piece becomes unable to be levitated whereby it drops naturally. The cycle of this snow producing operation is the unit of several seconds and, therefore, the snow can be produced and fallen continuously.

Abstract: PROBLEM TO BE SOLVED: To obtain a photosensitive material processor capable of carrying a photosensitive material at uniform speed by attaching a roller in contact with the photosensitive material so that the direction of fluff formed on the outer peripheral surface of the roller by grinding may have fixed relation to the carrying direction of the photosensitive material. SOLUTION: A drying roller 101 and a driven roller 102 are constituted by winding and sticking a water absorption sheet made of non-woven fabric or porous synthetic resin, etc., round the shaft center of metal, shaping it to have a specified outside diameter and grinding an outside diameter part. The attaching direction of the rollers 101 and 102 is regulated by using the chuck mechanism of a grinding device, and the rollers 101 and 102 are attached so that the forming direction of the fluff 301 may always have the fixed relation to the carrying direction of the photosensitive material. Desirably, the roller 101 is attached in a direction where the fluff 301 is tilted by the rotation (a). When the roller is attached in a direction where the fluff 301 bristles up (b), the fluff 301 is gradually worn and the carrying speed of the photosensitive material is changed.  By attaching the roller in the direction where the fluff 301 is tilted, influence caused by the wear of the fluff 301 is small even when the fluff 301 is worn.

Title: Magnetic head
Inventor: OKADA SUSUMU
IPC: G11B5/11
Filed: 1984-04-05
Abstract: PURPOSE:To reduce the leakage flux of a magnetic head and to improve the reproducing characteristic by forming a conductive layer at, at least, either one of the inside of a winding window and gap. CONSTITUTION:Conductive layers 5 are formed at the inside of a winding window 3 and a gap 4 by sputtering or the like. The conductive layer 5 is formed with a highly conductive metal, such as copper, silver, etc. Therefore, most of a leakage flux passing through the winding window 3 and gap 4 interlinks with a reproducing coil due to the eddy current reaction of the conductive layer 5 formed in these sections. As a result, the leakage flux is reduced and the reproducing output, especially, the output at high frequencies of this magnetic head is improved. Even when the conductive layer 5 is formed at either one of the gap 4 and winding window 3, the same effect can be expected.
