Abstract: This application relates to a stylus detection method applied to a terminal device provided with a first area for attaching a stylus. A magnetic attaching component for attaching and fastening the stylus to the first area is disposed in the stylus. An example method includes in response to detecting that an attaching object is attached and fastened to the first area, detecting the attaching object to obtain a detection result, where the detection includes detecting whether an attaching location of the attaching object is accurate. The method further includes in response to determining that the detection result is a target detection result, providing a first prompt to remind a user that the attaching location is inaccurate, where the target detection result includes that the attaching location of the attaching object is inaccurate.

Abstract: The disclosure relates to an improved Oil Red O staining solution, which consists of 0.5% of Oil Red O, 50% of ethanol, and 5% to 10% of salicylic acid. The staining solution does not contain organic solvents toxic to human bodies and has good safety and no toxic effect. The disclosure further relates to an Oil Red O staining method for cells or tissues, which is simple in operation, short in staining time, and easy to stain neutral fat in cells or tissues, with good staining effect and clean background. This method does not use isopropanol, which is safe and convenient and is suitable for popularization and application in laboratories.

Abstract: A molding device includes a male die, a master die core, a male die core located between the male die and the master die core, and a cutting mechanism received in the male die core. The cutting mechanism includes a cutting seat and a cutter. The cutting seat defines a latch slot. The latch slot includes a narrow portion and a wide portion communicating with the narrow portion. The cutter includes a plate body received in the narrow portion and a latch shaft located on the plate body. The latch shaft is engaged in the wide portion. When a plastic product is formed and a sprue gate is around the mold cavity, the plate body is configured to cut the sprue gate, and the plate body is movable relative to the cutting seat around the latch shaft, to prevent the plate body from sticking.

Abstract: A cutting apparatus configured for aligned with a gate of an injection molding part, includes a bottom board, a main adjustable mechanism attached to the bottom board, and a cutting mechanism. The main adjustable mechanism includes a driving device, a mounting member attached to the driving device, and a rotatable member rotatably attached to the mounting member. The rotatable member can be rotatable relative to the mounting member between a first position, where an acute angle is formed between the rotatable member and the mounting member, and a second position, where the rotatable member parallel to and abuts the mounting member.

Abstract: A cutting apparatus for cutting a gate of an injection molding part, includes a bottom board, a pushing mechanism attached to the bottom board; and a cutting mechanism. The cutting mechanism includes a driving member and a cutting member that is engaged with the driving member. The pushing mechanism moves the cutting mechanism in a first direction parallel to the bottom board, for the cutting mechanism to align with the gate. The driving member rotates the cutting mechanism, so the cutting mechanism can cut the gate.
