Title: Noncontact rotation angle acceleration sensor
Inventor: NAGASAKA NAGAHIKO
IPC: G01P15/13
Filed: 1985-10-03
Abstract: PURPOSE:To measure the angular acceleration of a rotating body without contacting by fixing the input shaft of an actuator on a rotating shaft, detecting the angle of displacement of an output rotor from an input rotor during the rotation of the rotating shaft, exciting and controlling the electromagnetic coil of the actuator so that the angle of displacement is invariably zero, and leading out an exciting current proportional to the angular acceleration. CONSTITUTION:The input rotor 10 made of a magnetic body is fixed on one shaft end of the rotating shaft 1 of a main motor whose rotating angular acceleration is detected and the output rotor 11 supported by a nonmagnetic support 16 is provided to the shaft 1. A permanent magnet 13 is provided on the inner peripheral surface of this rotor 11 axially opposite inductor teeth 12. An electromagnetic coil 21 wound around a stator 20 is excited by the electromagnetic coupling consisting of three elements, i.e. stator 20, and rotors 10 and 11 and the relative variation angle between the rotors 10 and 11 is detected by a noncontacting type sensor 22. For the purpose, the angle of displacement of the rotor 11 from the rotor 10 is detected by the sensor 22 even when the rotating shaft 1 and the coil 21 is brought under the excitation control of a servo system so that the angle of displacement is invariably zero, thereby detecting the acceleration from the exciting current.

Title: Washing method of ion exchange resin bed
Inventor: ODA KENJI
IPC: B01J49/00
Filed: 1983-11-24
Abstract: PURPOSE:To wash efficiently an ion exchange resin bed by introducing simultaneously pressurized air and backwashing water into a column, stripping thoroughly clads from the ion exchange resin beds in which the clads are accumulated and discharging the stripped clads together with a small amt. of the backwashing water to the outside of the column. CONSTITUTION:After the water level in a regenerating column 1 is adjusted to around the top surface of an ion exchange resin bed 2, pressurised air through an introducing pipe 4 and backwashing water through an introducing pipe 5 are simultaneously introduced into the column and while the outflow of the ion exchange resin bed to the outside of the column is prevented, the bed 2 is mixed and agitated to strip thoroughly the clads accumulated in the bed 2. When the top surface of the bed 2 arrives at the neighborhood of the upper part of the column, the introduction of the pressurized air and backwashing water is stopped and immediately the pressurized air is introduced through an introducing pipe 6 into the column to discharge a part of the backwashing water through a drain pipe 11 thereby discharging the relatively heavy clads. While the introduction of the pressurized air is continued the backwashing water remaining in the column is discharged from a drain pipe 3 installed near the part above the top surface of the bed 2 to discharge the relatively light clads.

Title: Semiconductor circuit
Inventor: TODOROKI TETSUO
IPC: H03K19/096
Filed: 1983-11-25
Abstract: PURPOSE:To keep an output level of an output terminal to a high level by constituting the 1st, 2nd, 3rd and 5th transistors (TRs) on the 1st substrate of the same polarity and constituting the 4th TR onto the 2nd substrate with opposite polarity to that of the 1st substrate. CONSTITUTION:Since a clock non-inverting signal is at a high level as shown in Fig. (a) at a period A9, an output potential at an output terminal 8 increases to a high level as shown in Fig. (e) through the 2nd TR5 in conductive state. As a result, the output potential of the output terminal 8 can be increased to a poten- tial lower by a threshold voltage Vth of the 2nd TR5 from the potential of a gate 11 and increasing. This is repeated, the potential of the output terminal 8 rises up to the high level of the clock non-inverting signal as shown in Fig. (a) and the potential of the gate 11 is a considerably high potential. Even if the potential of the gate 11 is lowered by the leakage of an electric charge of a capacitor 9, since the 4th TR13 is conductive by an output signal of an inverter 12, the high level of the output terminal 8 is kept.

Title: Automatic paper supply device
Inventor: TAKEUCHI TADASHI
IPC: B65H27/00
Filed: 1983-11-25
Abstract: PURPOSE:To maintain a stable separating action without increasing a contact even if a separating piece wears, by forming an end of the separating piece contacting a blank to have a section of an acute angle triangle. CONSTITUTION:A portion of a separating piece 6 contacting a manuscript 2 or a separating roller 4 has a triangular section with an end angle a. Even if this separating piece 6 wears, it is urged by a compression spring 5 to pivot clockwise while the contact center O transfers to the upstream side of the separating roller 4, so that the contact area is not so much changed. Further, since a press force of a compression leaf spring 5 to the separating piece 6 is applied to an end of a supporting leaf spring 7 even if the contact center O moves to the upstream side, the reduction of moment due to the reduction of distance from the fulcrum P of said spring 7 to the contact center O is covered by the increase of moment due to the increase of distance from the contact center O to the pressure point R of said spring 5 without any change in the contact pressure.

Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To improve a function by fixing a sliding strip on one of upper and lower part structures and fixing a laminated rubber support member free to slide along the sliding strip on the other. SOLUTION: A base isolation device is constituted of a laminated rubber support member 2 fixed on a continuous footing 1 and a sliding plate 4 fixed on a lower surface of a building wall 3 in the direction orthogonal to the footing 1. Thereafter, the support 2 is made free to slide on the plate 4 by sticking a sliding material 5 of Teflon etc., on an upper surface, the plate 4 is formed into a band shape out of stainless steel etc., so as to provide desired friction damping force, and a frame guide to guide sliding of the support 2 in the longitudinal direction is provided on a peripheral edge part.  At the time of an earthquake, the support 2 slides in the longitudinal direction of the plate 4 when the wall 3 is displaced in the longitudinal direction of the plate 4, and the support 2 absorbs the displacement by elastic force when the wall 3 is displaced in the direction intersecting the longitudinal direction of the plate 4. Consequently, it is possible to adjust base isolation performance in the horizontal direction and to easily set it in a narrow part of the continuous footing etc., when a laminated rubber support and a sliding support are combined by arranging plural numbers of the base isolation device in the proper directions.
