Title: Action controller for traveling object
Inventor: TSUCHIDA TORU
IPC: B25J9/16
Filed: 1985-05-27
Abstract: PURPOSE:To increase the speed of a traveling object by changing a deceleration curve to the one having a large deceleration degree as long as the control accuracy has the margin when the traveling object gets close to its target position. CONSTITUTION:When a traveling object gets close to its target position, the speed of the traveling object is reduced according to an initial deceleration curve set by an initial deceleration curve setting means 25. Here a deceleration curve having a large deceleration degree is read out among those stored in a deceleration curve storage means 24 when it is decided from the arithmetic result of an arithmetic means 21 that the control accuracy has the margin. Then a deceleration curve changing means 26 changes the read-out deceleration curve. Thus the traveling object is set quickly at its target position along the deceleration curve having a large deceleration degree. In such a way, the speed of the traveling object can be increased.

Title: Filling detecting device of transmission
Inventor: ASAYAMA YOSHIO
IPC: B60W10/11
Filed: 1987-05-11
Abstract: PURPOSE:To accomplish smooth speed change without breathing and to improve running performance by detecting the end of filling from a change rate of the number of revolutions of input shaft of a transmission to detect the end of filling simply and accurately. CONSTITUTION:After a speed change command is output, during a period of a filling time tf until a clutch back is filled up with oil, oil acts only for filling up the clutch back, and during the period tf, the clutch oil pressure is zero. The clutch oil pressure comes to initial pressure P0 at the completion of filling. On the other hand, though the number of revolutions of an input shaft of a transmission is normally held at a specified level nc during the period of time tf after a speed change command is output, at the completion of filling, it is decreased by force exerted on a clutch by the initial pressure P0. Accordingly, a change rate ¦nc-nt¦/nc of number of revolutions of the input shaft using the initial level nc as a standard, that is, a change ratio of number nt of revolutions at each point of time to number nc of revolutions at the time of outputting a speed change command is checked, and when the change rate is more than a preset value K, it is detected as the end of filling.

Abstract: PURPOSE:To obtain a stable pressure sensor, by adding a pressure to a cylinder comprising a magnetostrictive metal to detect changes in permeability caused in the cylinder. CONSTITUTION:A metal cylinder 3 comprising a cylindrical magnetostrictive Fe amorphous magnetic alloy is arranged at the center of a frame body made of a 45% Ni-Fe alloy with a cylindrical groove 2 at the center thereof and both ends thereof are fastened on the frame body 1. Difference in the thermal expansion coefficient is 0.3X10<-6> between the Fe amorphous magnetic alloy composing the metal cylinder 3 and the Ni-Fe alloy composing the frame body 1. A coil 4 is wound concentrically in the perimeter of the metal cylinder 3. A pressure applied at a pressure introduction port 2a causes a displacement in the amorphous magnetic alloy composing the metal cylinder 30mum thick. With this pressure per displacement, permeability of the amorphous magnetic alloy decreases to cause a change in inductance. The inductance value decreases monotonously down to 10kg/cm<2> in pressure to give a 1:1 correspondence to the pressure. An output thereof is detected with a circuit 5 for detecting a sensor output.

Filed: 1991-05-20
Abstract: PURPOSE:To obtain a cooling controlling device for electronic components which enhances cooling effect and also minimizes noise by carrying out the optimum control of the rotational speed of a fan according to the temperature in the device. CONSTITUTION:During stabilized time after a rise of an electric power supply and especially during a small fluctuating time accompanied by a relatively slow change of heat release values, variable rotating speed control of a cooling fan 13 is carried out based on a control signal of a feedback control section 16 which is output based on a detected temperature.

Title: Compound magnetic substance and manufacture thereof
Inventor: KOYUHARA TOKUKAZU
IPC: H01F1/00
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To remove noises in the ultra high frequency band by composing a compound magnetic substance of a continuous layer made of a magnetic substance and a non-porous diffused layer made of an insulating ceramic or a non-magnetic substance and by specifying the initial permeabilities and permittivities of these layers. SOLUTION: The initial permeabilities of a continuous layer (first layer) consisting of a magnetic substance and a non-porous diffused layer (second layer) consisting of an insulating ceramic or a non-magnetic substance are set in the range of 10-500, and their permittivities at 100 MHz 50 or lower. The method of mixing the magnetic material with the insulating ceramic material or the non-magnetic material, is adjusted so that the second layer is uniformly present in the first layer in a predetermined size. By limiting the size of the second layer to 0.5-200 μm, the second layer has substantially the same size as the grain diameter of the magnetic substance, thereby suppressing internal stresses caused due to distortions of the crystal structure and the like as much as possible and minimizing the deterioration of the permeability, which is a magnetic property.  Hence, good impedance characteristics can be obtained for high frequencies.
