Title: Wire wound electronic component and its manufacture
Inventor: AMADA YOSHIHIRO
IPC: H01F41/04
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To protect a bobbin and wire rods by relieving stresses and, at the same time, to suppress the fluctuation of the inductance value of the wire rods due to stress changes. SOLUTION: A conventional resin 54 and a ferrite-containing resin 56 are successively applied to a conductor 22 wound around the core 10 of a bobbin 16. Namely, the sealing resin of the conductor 22 has a two-layer structure of the conventional resin 54 and the ferrite-containing resin 56. Since the sealing resin is constituted in a resin structure such that has a soft inside layer and a hard outside layer, the inside layer of the sealing resin has low viscosity and a high flow property. Thus even if the ferrite-containing resin 56 is applied as the outside layer, stresses are relieved by means of the conventional resin 54 and the occurrences of cracks at the junctions of the bobbin 16, particularly, the junctions between the core 10 and flanges 12 and 14 are reduced.  In addition, the disconnection of the conductor 22 is prevented, because stresses with respect to the conductor 22 are also relieved.

IPC: B25J19/06
Filed: 1985-10-25
Abstract: PURPOSE:To markedly improve the collision prevention performance of a mechanical structure and reliability by installing an air injection device onto the periphery of the mechanical structure and installing a microphone for collecting the reflected sound of the jetted-out air and a drive controller. CONSTITUTION:The pressurized air P1, P2, and P3 is jetted out from a pressurized-air source, and jetted out in the form of the jetted-out air q1, q2, and q3 at a high speed from an air injection port 10a through a pipe 10b. When an attachment (mechanical structure) 2 having the injection port 10a approaches to an obstacle 15, and the distance becomes (l), the jetted-out air q1 collides and generates the reflection sound gamma1, which are collected by a microphone 11, and the distance (l) is discriminated from the sound pressure and the frequency. When the distance does not reach a set value, the jetted-out air advances, and when the distance reaches the second set value, a control signal M is outputted into a driving device 13 from a drive control device 12, and automatic deceleration or stop is performed to prevent collision. Since the jetted-out air q2, q3 is not in approached state to an obstacle, the reflected sound is not collected, and the non-existence of an obstacle is judged.

Abstract: PROBLEM TO BE SOLVED: To make driving stable and to reduce a control deviation sufficiently by executing driving with successive reference to a reference table wherein information on a change in thrust at each point in a driving direction is held. SOLUTION: According to a target value generated by a target position generating means 5, a movable element of a multiphase linear motor is moved to a first position at a prescribed speed and then it is driven to a second position at a prescribed speed.
