Abstract: A blade for a paper shredder cutting tool that includes an improved structure for one of two blades of each cutter of two rotary cutters of a paper shredder cutting tool. A protruding ring protrudes from a rim of a center hole of the blade, and the protruding ring and the blade are formed as an integrated body. The protruding rings not only enable disposition of paper chaff guides, but also will not deform because of thermal expansion and contraction when shredding paper, thereby preventing a gap from forming between the two blades, and thus the occurrence of paper jamming or wedging together of the blades of the upper and lower cutters.

Abstract: The present invention relates to an inkjet printer ink cartridge, which configures a sponge-free ink-filling device into a combined structure of a case and an ink outlet base body, which is then attached onto a printed circuit by PECVD. A stand having a recess on the ink outlet base body thereon can be used to dispose a socket. A nozzle plate connected to a heater chip can be inserted to the socket therein. The heater chip is electrically connected to a heating element in airflow guides formed on a surface of the socket thereto. A vertical wire attached to the socket is electrically connected to the vertical wire bent on the printed circuit at an edge of the stand. Therefore, when the heater chip has been used for some time and is required to be replaced, only the nozzle plate and the heater chip are independently replaced, whereas the case and the ink outlet base body can both be repeatedly used.

Abstract: A wireless transmission circuit enabling modulation of RF power amplification includes a signal processing circuit for outputting a signal that is modulated and then amplified at a cascade power amplification circuit including a plurality of power stages, and is then wirelessly transmitted to and received by a computer system. The wireless transmission circuit includes at least a power-setting unit for controlling a specific number of power stages included in the power amplification circuit to be used in the power amplification of the modulated signal. When a wireless input device employing the wireless transmission circuit is used within a short transmission distance, a lower transmission power is selected via the power-setting unit; and when the wireless input device is used at a long transmission distance, a higher transmission power may be selected to achieve the remote transmission. The wireless input device could therefore have extended battery life.

Abstract: An electrical connector to be electrically connected to a transmission cable plug. The connector includes a plastic base, a metal housing and at least one fastening assembly. At least one connection slot and a plurality of terminals are formed on the plastic base. Each of the terminals has a pin portion extending out of the plastic base. The metal housing covers the plastic base while exposing the at least one connection slot of the plastic base and the pin portions of the terminals to the outside. The at least one fastening assembly contacts the metal housing and thus is electrically connected to a circuit board. The at least one fastening assembly and the metal housing pertain to different parts.

Abstract: An infrared night vision camera apparatus includes a casing unit delimiting a first compartment and a second compartment separated from the first compartment, a light source module mounted in the first compartment, a shooting module mounted in the first compartment, and a power supply unit mounted in the second compartment.

Abstract: An insulated IC pressure sensor comprises a main body, enclosing a chamber, having a hole for letting in fluid pressure of which is to be sensed, a pressure-sensing integrated circuit (IC), placed inside the chamber, and a membrane, placed inside the chamber between the hole and the pressure-sensing IC, tightly sealing the pressure-sensing IC from a remainder of the chamber, creating a sealed space between the pressure-sensing IC and the membrane filled with electrically insulating fluid, so that sensing pressure of electrically conducting fluid will not directly contact and hence not adversely affect the pressure-sensing IC by short-circuits.

Abstract: A suitcase lock that can be opened either by setting a combination or by a key, in which dials of a suitcase lock are disposed with sleeves, and characterized in that a key tumbler is additionally fitted to the suitcase lock, and tongues located at a lower portion of a swing plate clamp connect to a slider. A groove at one end of the slider enables a push rod of the key tumbler to be clamped therein, and sloping grooves defined on another end enable the tongues of the swing plate to displace therein. In general, dials are used to control cuttings or circular arcs on the sleeves to operate the swing plate and hooking to a locked object and realize opening and closing of the lock. However, when in a locked state, without moving the dials, a key can be used to directly activate the key tumbler to push the slider, and thereby causes the swing plate to tilt in an opposite direction and the stopper at one end of swing plate can release the locked object from hooking position, thus opening the lock or suitcase.
