Title: Apparatus and method for direct-current-to-direct-current conversion in dual mode
Inventor: MAIKERU EMU UORUTAAZU
IPC: H02M3/156
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To automatically and smoothly perform switching of a DC-DC controller and control modes by supplying a capacitor with the current applied to the capacitor containing a means which controls peak current applied to the capacitor. SOLUTION: Once a switch S opens, a capacitor C supplies a load L with current, feedback voltage VFB being decreased. Once the VFB reaches the specified voltage δV less than a reference voltage Vr, a comparator 40 transits again an AND gate 46, a clock 44 and an error amplifier 42 to an enable high signal level. An inductor current is adjusted to continue hysteric cycle again. Since the inductor current is adjusted by both peak current and hysteresis mode, the transition between two modes is very smooth. Since the current applied to a capacitor is PWM current of constant frequency, synchronous noise is easily filtered.

IPC: B65D30/02
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To enable an easy opening of a bag by overlaying two kinds of films made of different materials and fusing left and right end rims. SOLUTION: Films 1a, 1b made of different materials which have been cut into congruent trapezoids are overlaid so that they align with each other. Left and right end rims 2a, 3a of one of the films 1a and left and right end rims 2b, 3b of the other film 1b are fused by heat-sealing, thereby manufacturing the packaging bag. The manufactured packaging bag has upper end rims 4a, 4b and lower end rims 5a, 5b not fused but is opened upward and downward. A polypropylene biaxially oriented film is used as the film 1a, while polypropylene span bond nonwoven cloth or the like is used as the film 1b. Since both are different in flexibility, they are not tightly attached even if both films 1a, 1b are overlaid. Therefore, at the time of opening an upper opening of the packaging bag, it can be easily opened without rubbing both films 1a, 1b in opposite directions between fingers.

IPC: G11B5/31
Filed: 1985-09-25
Abstract: PURPOSE:To reduce the error rate by retrogressing an end face opposed to a magnetic recording medium of a magnetic flux restoring core from an end face of a magnetic pole. CONSTITUTION:The end face 1a opposed to a magnetic recording medium of the magnetic flux restoring core 1 is retrogressed from the end face 2a opposed to the magnetic recording medium of the main magnetic pole core 2 by DELTAd. The retrogressed value DELTAd corresponds to the subtraction being the distance of the main magnetic pole core 2 from the surface of the magnetic recording medium from the distance of the magnetic flux restoring core 1 from the surface of the magnetic flux restoring core 1. In adopting the retrogressed value DELTAd by >=0.3mum, the sub pulse voltage is reduced to a half or below of the main pulse voltage. When the retrogressed value DELTAd is >=0.3mum, the error rate is rapidly decreased. Thus, the retrogressed value DELTAd is selected to be >=0.3mum.
