Patent TW-I319604-B (TW)
Title: Method of manufacturing flash memory cards
Inventor: TAKIAR HEM
IPC: G06K19/077
Filed: 2006-11-01
Granted: 2010-01-11
Abstract: A method is disclosed for forming semiconductor packages by a process of punching and cutting the packages from a panel of integrated circuits. During an encapsulation process for encapsulating the packages in a molding compound, portions of the panel may be left free of molding compound. Portions of the panel left free of molding compound may subsequently be punched from the panel. These punched areas may define chamfers, notches or a variety of other curvilinear, rectilinear or irregular shapes in the outer edges of the finished semiconductor package. After the panel is punched, the integrated circuits may be singulated. By punching areas from the panel, and then cutting along straight edges, a simple, effective and cost efficient method is disclosed for obtaining finished semiconductor packages of a variety of desired shapes.

Inventor: PAN CHING TSAI
IPC: H02M7/515
Filed: 2010-02-24
Granted: 2013-10-21
Abstract: An integrated-type high step-up ratio DC-AC conversion circuit with an auxiliary step-up circuit applies to converting a low DC voltage of alternative energy into a high AC voltage. The conversion circuit uses an isolated Cuk integration unit and an auxiliary step-up unit to form a multi-phase input and uses parallel charging and cascade discharging to boost the DC voltage in the DC side with a low voltage power switches and low duty cycle and then converts the boosted DC voltage into AC voltage. The auxiliary step-up unit not only shares the entirety of power but also exempts the DC-side circuit from using high voltage power switches, whereby the cost of elements is reduced. Further, the conversion circuit can decrease the switching loss and conduction loss of the DC-side switches and promote the efficiency of the circuit.

Abstract: An arrangement for damping and absorption of sound in rooms. The purpose of the invention is to provide a sound damping even at very low frequencies e.g. 50 Hz and simultaneously improve speech comprehension in the entire room by reduction of the resonance time. Another purpose is to be able to vary the acoustic absorption and in that way even vary the resonance time over the entire part of the frequency area. This has been achieved by the fact that the sound absorbents 14 in the form of plates mats or similar are arranged at an angle with at least one corner area (11) formed by the walls 12 and ceiling 13 of the room in the corner area 11 behind the absorbent 14 an air volume is trapped so that the absorbent due to the sound influence has a membrane effect. The inclination and for position of each absorbent 14 can be varied individually or in group.
