Abstract: A card reading device includes an insulating housing, at least a set of conductive terminals, a rear wall, and a shielding member. The rear wall includes a metal plate and a plastic plate that is formed by insert molding, which has a stable configuration and is unlikely to shake or distortion. The rear wall reliably presses and contacts with a top edge of a soldering portion of the conductive terminals, which is easier to be soldered so as to avoid soldering skipping or solder voiding. Moreover, the shielding member presses a top edge of the rear wall so as to make the rear wall securely press the soldering portion. Furthermore, the rear wall includes a plurality of openings therein, which make the gas circulate so as to avoid solder voiding. Thereby the qualified ration is improved.

Abstract: A process of manufacturing a tooth of a dipper bucket of a shovel is disclosed. The tooth has a larger joining portion coupled to the dipper bucket and a sharp portion. The process comprises cooling the molded tooth in a furnace at about 920° C., suddenly cooling the tooth in a fluid contained in the furnace, heating the tooth at about 460° C., slowly cooling the tooth in the air, supporting the tooth in the furnace with the joining portion immersed in the fluid and the sharp portion exposed in the air, and producing the finished tooth. The teeth are less brittle and more ductile while having a sufficient hardness. The teeth can dig further into earth for increasing load of the dipper bucket per shovel.

Abstract: An LED chap lamp apparatus has a heat sink with a reflector, an LED lamp module and a heat pipe. The LED lamp module is assembled on an inside of the reflector for reflecting light of the LED lamp module. The two ends of the heat pipe each connect to the LED lamp module and the heat sink to conduct and disperse the heat produced form the LED chips to increase the lifetime and the light-emitting efficiency of the LED chap lamp apparatus.

Abstract: A wafer container having a latching mechanism utilized to lock the door of the wafer container in an airtight status. The latching mechanism comprises a cam rotated to move a link and a locking plate pivoted to one end of the link, and a guide block adapted to guide the locking plate sliding into an insertion hole in the container body of the wafer container by using a straight guide means and a curved guide means of the guide block and then to turn the locking plate about pivot rods at the link, causing the locking plate to withstand against part of the container body and to hold down the door toward the inside of the container body and to lock the door in an airtight status.

Abstract: A management system for managing information of monitor wafers stored in a storage center includes an operation rule module for determining the next manufacturing process for each of the monitor wafers according to its wafer number and wafer condition, an information update module for updating the information of the monitor wafers in a database according to the results made by the operation rule module, an inventory module for computing an inventory quantity of the monitor wafers according to the wafer numbers and the wafer conditions of the monitor wafers, a warning module for checking whether the inventory quantity of the monitor wafers is less than the quantity of the safety stock or not and sending a warning message when the inventory quantity of the monitor wafers is less than the quantity of the safety stock, and a display module for showing the wafer conditions and the inventory quantity of the monitor wafers.

Abstract: A vacuum-sealed container includes a flexible waterproof plastic bag on which there are a plurality of inflatable C-shaped tubular ribs and a plurality of horizontal tubular inflatable ribs, the horizontal tubular ribs being connected internally and externally to the C-shaped tubular ribs, and on one of the C-shaped tubular ribs there is a nozzle through which air can be forced into the C-shaped tubular ribs and tubular horizontal ribs to form a three-dimensional container, thereby providing a space for storing articles, the bag having an open end for putting articles therein, whereby the vacuum-sealed container can be inflated and kept on a flat surface to form a three-dimensional container thereby making it easier to put articles inside the bag and enabling it to become flat and foldable when not in use, and therefore isolating the articles from water, moisture and mildew.

Abstract: A connector interference prevention grounding mechanism comprises a circuit board with a connector on one side. The connector has a plurality of slots, each slot contains a sleeve internally. One metal board each is on top and bottom of the connector. Internal to the side slots on both end of the connector has a grounding sleeve. A C-shaped spring tongue is in the middle of the grounding sleeve. A convex point is on the bottom of the metal board and beneath the C-shaped spring tongue. Therefore by the C-shaped spring tongue of the grounding sleeve contacting the convex point of the metal board, the grounding sleeve also connects to the circuitry of the circuit board so that the electromagnetic wave and static electricity absorbed by the metal board can be conducted to the circuit board through the grounding sleeve to eliminate the electromagnetic wave and static electricity.

Abstract: A pressing bar for connecting legs of connectors includes a connector with a plurality of slots. A sleeve is inside each slot with a connecting leg that is soldered on a connecting point of a circuit board. The connecting legs are further fixed onto the circuit board with a pressing bar. The pressing bar includes a pair of pressing ears on both ends and a plurality of troughs on the bottom. A fastening hole is on both ends of the connector. By placing the pressing ear of the pressing bar into the fastening holes of the connector, the pressing bar is fixed on top of the connector and the troughs of the pressing bar are firmly attached on top of the connecting legs of the sleeves. Thus the connecting legs are pressed on top of the connecting points so as to avoid bad connections and open circuit conditions.
