IPC: B41J29/13
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a stable operation force by a very simple method by allowing at least one engagement part to be a center-beam type elastic engagement part wherein both end parts are supported by a member, respectively, at a specified position of the member and provided a member which regulates displacement of the elastic engagement part in a specified direction adjacent to it. SOLUTION: When a lid member 3 is closed in an arrow-A direction from above, a tip end lower are part 3a' of a non-elastic engagement part 3a is made to hit an upper part tip end of an elastic engagement part 1c, and a horizontal force is made to act on the elastic engagement part 1c as the engagement part 3a moves downward. The engagement part 1c formed at a beam part 1d causing distortion is displaced rightward (arrow E), so that the engagement part 3a comes under the engagement part 1c. Here, the force acting on the engagement part 1c is released to cancel the distortion of the beam part 1d so that the engagement part 1c is displaced in an arrow F direction to return to an initial position, and the lid member 3 is fixed for preventing disengagement upward of the engagement part 3a. Thus, breakage is prevented even with a small strength of an elastic part.

Title: Ringing choke converter
Inventor: TANAKA HIDEHIRO
IPC: H02M3/338
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency under minimum load by employing a ringing choke converter connected with a delay circuit for prolonging the off time of an inverter toward minimum load as a transformer having an uneven core gap. SOLUTION: A ringing choke converter comprises a transformer 2 in which efficiency under minimum load is enhanced by partially decreasing the core gap thereby making gentle the gradient of current flowing through an inverter 6 under minimum load. Furthermore, a circuit 15 for delaying the turn on time of the inverter 6 as the load current decreases, e.g. a ringing choke converter, is connected with a winding 4 for driving the inverter 6. Since the off time of the inverter 6 is prolonged, switching loss ΔP1 per unit time is reduced and the efficiency can be enhanced significantly under minimum load.
