Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide an insulating resin layer excellent in thermal, mechanical and physical characteristics by blending a specific quantity of fibrous filler having a specific aspect ratio with an insulating resin. SOLUTION: An inorganic insulator fibrous filler such as calcium carbonate or an organic insulator fibered filler such as polyoxytbenzoyl having the aspect ratio of 5 or above, preferably 10 or above, is added at 10-60% to an insulating resin singularly or in combination of multiple kinds.

There is no problem for the organic filler, however the average fiber length is set to 10 μm or below to improve the inner beer hall workability by laser when the inorganic filler is used. A granular filler of 30-70 wt.% is added to the fibrous filler to improve the anisotropic property peculiar to the fibrous filler.  The mechanical strength, thermal expansion coefficient and crack resistance are improved, and warping or peeling can be suppressed.

Title: Microwave oven having rush current suppression function
Inventor: TOMIMATSU HIROKAZU
IPC: H05B6/68
Filed: 1989-03-29
Abstract: PURPOSE:To suppress the rush current of a high-tension transformer by measuring a delay time elapsed from the time when a microwave generation command is outputted to the time when current is applied to a switching means, thus operating the switching means prior to the time when a rush current is minimized, by a delay time. CONSTITUTION:For driving a turn table motor 12, a H-level signal is outputted from an output port A at the time of Tk. This causes the coil 103 of a relay to be applied with current so that relay contacts 101, 102 are made conductive so as to feed power from a power source 2 to the motor 12. At the time of Tm after a elapse of Ti, based on the last transition time Tl of a power source synchronizing signal, since the motor is certainly turned on, the H-level signal is outputted from an output port B, wherein T1=T2- T, T2 being 3/4 period of the power source synchronizing signal. Thus, the contacts 141, 142 are made conductive at the time Tm when the rush current is made minimum for starting to flow current at a high tension transformer 18. Accordingly, the high tension transformer is less liable to be applied with a large current at the time of starting of current-applying.
