Abstract: A candle warmer lamp is provided, which includes a seat, a connection frame, a first light-emitting component, and a second light-emitting component. The seat is provided with a bearing surface configured to carry a container accommodating an aromatherapy candle. One side of the seat away from the bearing surface is provided with an accommodation groove, the connection frame is connected to the seat. The first light-emitting component is provided in the connection frame, a light-emitting end of the first light-emitting component is faced to the bearing surface. The second light-emitting component is accommodated in the accommodation groove. Light emitted by the second light-emitting component passes through an outer circumference side of the seat. Therefore, by providing with the second light-emitting component, a bottom of the candle warmer lamp can emit light, and a user can start the first light-emitting component and/or second light-emitting component for lighting or fragrance release.

Abstract: Managing source code change set commits to decrease time to identify software bugs in versions of a software project is provided. An initial order of relevant commits corresponding to the software project is determined in a priority queue based on a weight of each respective commit of the relevant commits. The initial order of the relevant commits is adjusted in the priority queue based on a build distance between the relevant commits of affected source files. A particular commit having a highest priority ranking is selected in the priority queue for build and test. The build and the test of the particular commit having the highest priority ranking in the priority queue is executed.

Abstract: A counter-rotating fan, comprising two impellers and a motor. The motor is used for driving the two impellers to rotate. The two impellers are axially spaced apart from each other, and are divided into a first-stage impeller and a second-stage impeller. When the counter-rotating fan operates, airflow is blown to the direction of the second-stage impeller by means of the first-stage impeller. At least one impeller has turns of blades arranged in the radial direction of the impeller. Blades of each turn are spaced apart from each other around a hub of the impeller, and a spacer ring is connected between two adjacent turns of blades. The counter-rotating fan is stable in rotation and good in cooling effect, it is not easy to deform, and the wind is strong in the center.

Abstract: Disclosed is a fan. The fan includes a support; a first motor installed on the support, the first motor having a first rotation shaft; a first blade installed on the first rotation shaft; a second motor installed on the support, the second motor having a second rotation shaft and being coaxial with the first motor; a second blade installed on the second rotation shaft, a tilt direction of the second blade being opposite to a tilt direction of the first blade; and an electric control board electrically connected to the first motor and the second motor and configured to control a relative rotation of the first motor and the second motor.

Abstract: Disclosed is a fan. The fan includes a support, a first motor, a first blade, a second motor, a second blade and an electronic control board. The first motor and the second motor are both installed on the support. The first motor is coaxial with the second motor. The first motor has a first rotation shaft and the second motor has a second rotation shaft. The first blade is installed on the first rotation shaft. The second blade is installed on the second rotation shaft. A torsion direction of the first blade is opposite to a torsion direction of the second blade. The electric control board is electrically connected to the first motor and the second motor, and includes a speed ratio adjustment device. The fan can provide a variety of air outlet modes and can quickly adjust between different air outlet modes.

Abstract: Provided is a phase transfer catalyst for producing an aromatic aldehyde compound, comprising a compound of formula I, wherein R1 is hydrogen, methyl, ethyl, isopropyl, isobutyl or tertbutyl; R4, R5 and R6 are independently selected from alkyl groups containing 1 to 6 carbon atoms; and X is fluorine, chlorine, bromine or iodine.

Abstract: A mounting apparatus is used to secure a disk drive, which defines a mounting hole therein. The mounting apparatus includes a bracket and a mounting member. The bracket is configured for receiving the disk drive therein. A through hole is defined in the bracket. A locking tab is formed on the bracket. The mounting member includes two arms and an operating portion. One end of each of the arms is pivotably secured on the bracket so that the mounting member is pivotable relative to the bracket, and the other end thereof connects with the operating portion. A positioning portion is formed on the operating member. The operating portion is capable of engaging with the locking tab of the bracket for inserting the positioning portion into the mounting hole of the disk drive via the through hole of the bracket.

Abstract: An exemplary method for forming gaps in a micromechanical device includes providing a substrate. A first material layer is deposited over the substrate. A sacrificial layer is deposited over the first material layer. A second material layer is deposited over the sacrificial layer such that at least a portion of the sacrificial layer is exposed. The exposed portion of the sacrificial layer is etched by dry etching. The remaining portion of the sacrificial layer is etched by wet etching to form gaps between the first material layer and the second material layer. One or more bulges are formed at one side of the second material layer facing the first material layer, and are a portion of the sacrificial layer remaining after the wet etching.
