Title: Fluid control valve
Inventor: TAKEUCHI TAKAHIKO
IPC: G05D7/06
Filed: 1985-06-24
Abstract: PURPOSE:To improve the operability of a fluid control valve by setting a drive circuit and an actuator, a position sensor and a control circuit and the control circuit and the drive circuit close to each other respectively. CONSTITUTION:An analog indication signal 2 is converted into a serial digital signal by a modulation transmitter 1 and sent to a fluid control valve 12 via a transmission line 3 using an optical fiber after modulation of the pulse width. The valve 12 consists of an actuator 7, a fluid control valve mechanism 8 and a working transformer 9, together with a reception demodulator 4 and a drive circuit 5 unified together. The circuit 5 contains a control circuit which sets a flow rate indicated by the signal 2 based on a position detecting signal 11. Thus the transmission lines are shortened for the drive signal 6 of the actuator 7, the drive signal 10 of the transformer 9 and the detecting signal 11 respectively, external noise is difficult to mix because the part 8 is unified with the circuit 5 for the valve 12.

Filed: 1986-06-13
Abstract: PURPOSE:To prevent the adsorption of dust or smoke on the display panel of a CRT or the generation of the uncomfortableness due to the discharge of electrostatic charge by providing a CRT in the space between the inner layer and the outer layer of which metallic vapor and inert gas are sealed. CONSTITUTION:Inert gas 11 sealed in the inside space 5 of double layers is heated on the inside layer 3 by means of the heat generated in a CRT and cooled on the outside layer 4, so that the convection of the said gas is generated in the space 5, then the convection of the metallic vapor 12 sealed in the space 5 is generated too. When the convective metallic vapor 12 is contacted to the surface of the space side of the inner layer 3, electrostatic charge 10 on the surface is transfered to the metallic particle 12 of the metallic vapor contacted to the surface. The metallic particle 12 having the transfered electrostatic charge is moved in the space 5 by the convection, and transfers the charge to the electrostatic charge collector electrodes 61, 62 when it is contacted to the elecrodes. The lead wire potions 71, 72 of the electrodes 61, 62 are connected to the frame of the CRT display device, so the charge is flowed in the frame to neutralize the high voltage electrostatic charge.

IPC: G01L3/10
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain an electric power steering for automobile for maintaining operation feeling without any feeling of wrongness even if failure such as voltage drop and instantaneous interruption occurs in the drive power supply of a torque sensor. SOLUTION: By detecting the failure in a power supply V1 of a torque sensor 108 by the self-off function of a voltage-monitoring circuit 3 or a fail switch 2, the gain of an auxiliary steering force operation means 1 is gradually decreased and a torque command Ts to an electric motor for giving auxiliary steering force to an auxiliary steering device is gradually decreased. As a result, even if the power supply V1 fails while the auxiliary steering force is in operation, the auxiliary steering force cannot be lost immediately. Since the auxiliary steering force is gradually attenuated, a driver can continue stable handle operation without any feeling of wrongness where a steering handle suddenly becomes heavy.

Title: Low frequency electromagnetic induction heater
Inventor: IGUCHI ATSU
IPC: H05B6/04
Filed: 1989-05-29
Abstract: PURPOSE:To prevent electromagnetic vibration by forming a heater from six induction coils, allowing any pair of adjoining coils to receive supply of the power from either of three-phase AC power supplies, and feeding the current to induction coils in substantially symmetrical positions. CONSTITUTION:An induction heater is formed from at least six induction coils, which are arranged cylindrically. If they are designated as A1 thru A6, the A1 and A2 as adjoining are wired to the U phase of the three-phase power supply, the A3 and A4 to the V-phase, and the A5 and A6 to the W-phase. The wiring shall be made so that current flow occurs to the induction coils in substantially symmetrical positions. That is, the A1 and A4 are wired together, the A2 and A5, and also A3 and A6. This causes continuous generation of electromagnetic attraction force to allow pulling of the object to be heated continuously, which should prevent generation of vibratory sound even though a low frequency AC power supply is used.

IPC: A63B71/08
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To effectively play the natural role of fastening and fixing of a supporter in an area except a bending part, and facilitate the bending in the bending part by forming a curved recessed part forming a non-pile area braided by float mesh on the inside area opposed to a curved protruding part braided with additional yarns on the outside area. SOLUTION: A longitudinal cylindrical supporter 1 for a bending part such as elbow or knee is formed as the whole by pile braiding in the other area excluding a fixed area on the inside. The outside area 2 of a bending part is formed into a vertically long thick elliptic form by pile-braiding with additional yarns 4, and the inside area 3 of the bending part is formed into a thin braided fabric as a non-pile area braided by float mesh. Therefore, the outside area 2 of the bending part is curved slightly outward, and the inside area 3 is curved inward. Thus, when the supporter 1 is installed to the elbow, for example, the outside area 2 of the bending part is situated on the outside of the elbow, and the bending part inside area 3 on the inside, the bending of the elbow part can be performed without excessiveness.
