Abstract: A stopcock includes a housing and a sealing insert. The housing includes a first surface, a first blind hole defined in the first surface, and a through hole defined in a first bottom surface of the housing in the blind hole. The through hole tapers toward the bottom surface. The sealing insert includes a first engaging portion and a second engaging portion connected to the first engaging portion. The first engaging portion is engagingly received in the blind hole. The second engaging portion is engagingly received in the through hole.

Abstract: A shutter includes a first insulating substrate, a first electrode layer, a second insulating substrate, a second electrode layer, and a light-blocking layer. The first electrode layer is formed on the first insulating substrate. The first electrode layer includes layer portions insulated from one another. The second electrode layer is formed on the second insulating substrate. The light-blocking layer is disposed between the first and second electrode layers. The light-blocking layer includes a liquid and opaque and charged balls movably distributed in the liquid. At least one layer portion is selected. The at least one selected layer portion and the second electrode layer are connected to respective positive voltage and negative voltage to generate an electric field to the charged balls. The charged balls are attracted by the electric field to arrange in a configuration corresponding to the at least one selected layer portion to block light.

Abstract: An exemplary lens module includes a barrel, a first lens fixedly disposed in the barrel, a second lens movably received in the barrel, and a pressure control device. The barrel includes a peripheral side wall. A hole is defined in the peripheral side wall. The first lens, the second lens, and the barrel together define a chamber. The chamber communicates with the hole. The pressure control device communicates with the hole so as to change the gas pressure of the chamber, thereby moving the second lens relative to the first lens.

Abstract: A mold includes a parting surface, runners, mold cavities, gates and primary air-venting grooves defined in the parting surface. The gates connect the respective runners to the corresponding mold cavities. Each primary air-venting groove includes an air-receiving groove portion and an air-venting groove portion in communication with the air-receiving groove portion. The air-receiving groove portion communicates with the gate and surrounds the corresponding mold cavity. The air-venting groove portion extends to and terminates at a corresponding edge of the parting surface.

Abstract: A portable electronic device includes a housing and a main body. The housing has an image pickup window. The main body is accommodated in the housing. The main body includes a first lens module, a second lens module, a rotatable base and a driving element. The rotatable base carries the first lens module and the second lens module thereon.
