Abstract: An oxygen-compression apparatus has a driving device, multiple rotating wheels, multiple driving rings, multiple rocking cylinders and multiple connecting hoses. The driving device has a driving shaft with a central axis. The rotating wheels are eccentrically attached on and rotated with the driving shaft and are located respectively at different angles relative to the central axis of the driving shaft. The driving rings are rotatably mounted respectively around the rotating wheels. The rocking cylinders are connected respectively to the driving rings and each has a housing and a piston rod. The piston rod has a first end extending into the inner space of the housing to form a compression chamber in the inner space and a second end pivotally connected to a corresponding one of the driving rings. The connecting hoses are connected between the compression chambers of adjacent rocking cylinders.

Abstract: A lamp driving circuit with a floating power supply driver includes a microcomputing unit, a floating power supply driver, and a driving unit. The microcomputing unit and the floating power supply driver are independent integrated circuits and manufactured under a normal voltage. The floating power supply driver is coupled to the microcomputing unit via two independent high-pressure coupling capacitors, instead of sharing the same ground with the microcomputing unit. The microcomputing unit and the floating power supply driver provide at least one low-voltage driving pulse output pin and one high-voltage driving pulse output pin to control the power transistor inside the driving unit. The power transistor turns on/off at appropriate time so that a lamp connected to the driving unit can be lit up by a driving high voltage.

Abstract: A radar sensor for a vehicle and having a fine-tuning function includes a base forming a chamber to pivotably receive a sensor module. The sensor module can be adjusted in its pantoscopic angle and direction, so as to set a sensing range accurately. A packing block is configured at an inner wall of the chamber, which can be controlled by an adjustment part configured at a surface of the base. When an operator adjusts the sensor to an appropriate angle, the adjustment part at the surface of the base can pack the sensor, so as to achieve an objective securing the sensor module in a desired position.

Abstract: A decorative tree uses a control circuit to operate multiple light strings and a speaker. Based on different types of music output by the speaker, the control circuit determines the light strings to be properly turned on or off. Therefore, the visual effects generated by these light strings coordinate with the output music.

Abstract: A receptacle for a CPU has a seat, a cover, a heat sink, and multiple fastening members. The seat is mounted on a motherboard, and a recess is defined in the seat with multiple flexible metal pins provided therein. Multiple resilient members are mounted in the recess. The cover is mounted on the resilient members and can slide in the recess. The heat sink is mounted on the seat, contacting the CPU and secured by the fastening members. The receptacle of this design omits the metal housing, has a heat dissipation capability, and can help reduce the cost of a computer.

Abstract: A composite circuit board comprises multiple soft panels evenly mounted on a rigid panel. The soft panels are positioned on the rigid panel in proper alignment via locating pins on the rigid panel and corresponding holes in the soft panels. The soft panels are securely bonded to the rigid panel to form the composite circuit boards. The smaller size of the soft panels minimizes the alignment problems caused by the different heat expansion rates of the soft panel and the rigid panel.

Abstract: The invention relates to jet devices and the operating methods thereof and can be used in order to produce and intensify the oil inflow from a well. The inventive device comprises a jet pump arranged on a tubing string in the well with a casing string. An active nozzle and a mixing chamber are coaxially arranged in the body of said pump and a bypass channel provided with a mounting seat for a sealing unit with an axial channel or for functional inserts with autonomous instruments is embodied. The output of the pump is connected to an annular space of the tubing string, the input of a channel for supplying a working medium to the active nozzle being connected to the internal space of the tubing string above the sealing unit. A channel for removing the medium pumped out from the well is connected to the internal cavity of the tubing string below the sealing unit. Said device is also provided with a radiation source and a receiver-transducer of physical fields and a packer.

The SOI substrate is an SOI wafer which is obtained by forming an oxidized film on a first silicon wafer, forming a separation layer by hydrogen ion implantation into the first silicon wafer via the oxidized film, bonding the first silicon wafer onto a second silicon wafer, and cleaving the first silicon wafer from the second silicon wafer at the separation layer so that a silicon membrane layer is formed on the second silicon layer via the oxidized film.

Abstract: A detachable screen protector assembly mounted on a screen frame of a monitor having a lower front surface and an upper front surface and has a screen protector and a fastening apparatus. The fastening apparatus has at least one couple of a bracket and a detachable hook. The bracket is mounted on the screen frame to hold the screen protector. The detachable hook corresponds to the bracket, is mounted the screen frame above the bracket and holds the screen protector. The detachable hook has a bracket member mounted on the upper front surface of the screen frame and a hooking member detachably mounted to the bracket member and holding the screen protector. Because the hooking member may disengage from the bracket member, the screen protector can be detached from the screen frame to be cleaned or be mounted on other monitors when people change their monitor.
