Abstract: A punch type substrate strip includes a plurality of substrate units, a plurality of slots and at least one plating-trace collecting hole. The slots are formed around the substrate units. The plating-trace collecting hole is located outside the substrate units. The substrate strip is provided with a plurality of connecting pads, a plurality of first plating traces and at least one second plating trace. The connecting pads are disposed in each substrate unit, and the first plating traces and the second plating trace are electrically connected to the connecting pads. The first plating traces have a plurality of first broken ends located in the slots. The second plating trace is extended across a region located between the slots, and has a second broken end located in the plating-trace collecting hole. Accordingly, more extensive space for plating traces can be provided.

Abstract: A twin pedal assembly for a bass drum includes a first pedal and a second pedal. A linkage is connected between the first pedal and second pedal and has a bar. A passage is defmed through the bar. Multiple threaded holes are defmed through an upper side of the bar inclined towards a user. Multiple threaded fasteners are screwed into the threaded holes and inclined towards the user. Two shafts are inserted respectively into the passage and secured by the fasteners. Two universal joints are mounted respectively between free ends of the shafts and the pedals. Each universal joint is composed of a first barrel connected to the shaft, a second barrel connected to the first pedal/second pedal and a pin to pivotally mounted between the first barrel and second barrel. Whereby, it is very easy and convenient to loosen/tighten the fasteners to adjust a distance between the pedals.

Abstract: A winding mechanism for a window blind includes a base having two slideways, a rotation member rotatably mounted on the base and having an outer wall formed with a threaded guide portion, and a guide seat having an inner wall formed with a threaded guide hole screwed onto the threaded guide portion of the rotation member and an outer wall formed with two guide posts each provided with a roller slidably mounted in a respective slideway of the base. Thus, when the lift cord is wound around the rotation member, the guide seat is movable successively on the rotation member by guidance of the roller, so that the lift cord is wound around the rotation member serially and smoothly by guidance of the guide seat, thereby preventing the lift cord from being tangled.

Abstract: A substrate strip for a transparent package has a top surface, a bottom surface and an injection region through the top and bottom surface. The top surface includes a plurality of package regions and a plurality of runner regions. The injection region is disposed between the package regions and is coupled to the runner regions. The injection region has a sidewall with a releasing layer for preventing the residual of clear compound from remaining at the injection region of the substrate strip.

Abstract: A controller is disclosed for a motor. The motor includes a first terminal and a second terminal. In a positive mode, the first terminal is connected with the positive electrode of a power supply, and the second terminal is connected with the negative electrode of the power supply. In a negative mode, the first terminal is connected with the negative electrode, and the second terminal is connected with the positive electrode. The controller includes a central conductive device comprising a first conductor connected with the positive electrode of the power supply, a second conductor connected with the first terminal, a third conductor connected with the negative electrode of the power supply and a fourth conductor connected with the second terminal. An upper conductive device includes a first conductor for contacting the first and second conductors of the central conductive device and a second conductor for contacting the third and fourth conductors of the central conductive device in the positive mode.

Abstract: The present invention provides a throughput monitoring and analysis system and method, comprising: a factor-fetching means and a terminal means. Wherein the factor-fetching means fetches a plurality of raw time data of the production factors corresponding to selected operation events during execution of operation events of the complex machine. The terminal means stores the time data and related information of the production factors and displaying the monitoring results according to set required condition and the data and information.

Abstract: An energy saving multiplication device and its method is disclosed. The multiplication device includes a dynamic range determination unit, a Booth encoding/decoding unit and a counter array. The dynamic range determination unit determines dynamic ranges of the numerical values to be multiplied together and outputs after processing according to the dynamic-range size relation of the input data. The Booth encoding/decoding unit couples to the dynamic range determination unit. The counter array couples to the Booth encoding/decoding unit for accumulating the partial products to obtain the products of the input data.

Abstract: A charger is provided for charging a battery from a source and capable of detecting and switching polarity. The charger includes a first detection block for connection with the source, a second detection block for connection with the source, a first switch connected with the first detection block, a second switch connected with the second detection block and a switch actuation block connected with the switches and for connection with the battery. The switch actuation block includes a first relay and a second relay. The first relay is turned on for sending power from the source to the battery when circuit flows through the first detection block and the first switch. The second relay is turned on for sending power from the source to the battery when circuit flows through the second detection block and the second switch.
