Abstract: Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.

Abstract: A keyboard device for an electronic device includes a keyboard main body and a protection plate member. The protection plate member is pivotally coupled to the keyboard main body. Consequently, the keyboard main body is covered by the protection plate member, or a first angle is formed between the protection plate member and the keyboard main body. The protection plate member includes a first plate and a second plate. The keyboard main body is pivotally coupled to a first end of the first plate. The second plate is pivotally coupled to a second end of the first plate. After the protection plate member is rotated relative to the keyboard main body and the first angle is formed between the protection plate member and the keyboard main body, the protection plate member is further adjusted to a selected usage mode.

Abstract: A protective cover assembly is provided, which includes a bracket and a biaxial structure. The bracket has a first portion and a second portion pivotally connected to each other. The biaxial structure has a first rotating shaft and a second rotating shaft, in which a portion of the first portion of the bracket away from the second portion is configured to be pivotally connected to or separated from the first rotating shaft or magnetically connected to or separated from the first rotating shaft, and the second rotating shaft is configured to be pivotally connected to a component.

Abstract: A laser detection system includes a light source module, an optical isolator, a scanner, and a detector. The light source module is configured for emitting a first laser having a first polarization direction. The optical isolator is on an optical path of the first laser configured to emit a second laser by transmitting the first laser from the light source module and prevent the second laser from transmitting toward the light source module. The scanner is on an optical path of the second laser and configured for reflecting the second laser to project a reference light to the target to be tested. The detector is configured to receive detection light reflected by the target to be tested and obtain position information of the target to be tested according to the detection light.

Abstract: A keyswitch structure includes a base plate, a keycap, a first support, and a second support. The keycap is located above the base plate. The first support is connected to and between the keycap and the base plate and has an upper connection portion, a lower connection portion, and a protruding limitation portion. The upper connection portion is located between the lower connection portion and the protruding limitation portion. The first support is rotatably connected to the keycap and the base plate through the upper connection portion and the lower connection portion respectively. The protruding limitation portion is located close to and under the cap body. The second support is connected to and between the keycap and the base plate. The keycap moves up and down relative to the base plate through the first support and the second support.

Abstract: A proportion-integration-derivation (PID) kettle structure includes: a kettle upper cover; a water filling cap, embedded into kettle upper cover; and a PID element, fixed onto inner side of water filling cap, to indicate usage time of a filter core in a kettle. The PID element includes: a guiding axis, disposed at an end inside the water filling cap; a pushing rack, sleeved around the guiding axis; a reset spring, disposed between pushing rack and guiding axis; an arc-shape rack pushing boss, disposed symmetrically on both sides of the pushing rack, used to push the pushing rack to move, when water filling cap is opened or closed; a driving gear, disposed at front end of the pushing rack, to act in cooperation with the pushing rack; and a driven gear, disposed below the driving gear, and connected to rotate along with the driving gear.
