A porous silicon nitride capillary core for a loop heat pipe is formed by firing raw materials including silicon nitride powder, a sintering aid and a pore forming agent, wherein the content of silicon nitride is not smaller than 90% by weight. The average grain size of the silicon nitride powder ranges from 0.1 micrometer to 10 micrometers, and the proportion of the alpha-phase silicon nitride is larger than 90%. Micropores included in the porous silicon nitride capillary core communicate with one another, the pore diameter of the micropores ranges from 0.5 micrometer to 5 micrometers, and the open porosity is larger than 50%. The porous silicon nitride capillary core is formed by sintering the silicon nitride powder, has good chemical stability and is resistant to corrosion of acid and alkali, decomposition of working media in the loop heat pipe can be effectively restrained, and the service life of the loop heat pipe is prolonged. Meanwhile, the porous silicon nitride capillary core is high in brittleness and good in machining performance, the surface micropores cannot be closed during outer wall finish machining, and the high open porosity of the capillary core is guaranteed.

The invention discloses an automatic change-over switch with manual and automatic switching mechanisms. The automatic change-over switch is provided with a fixed panel and a sliding panel, the automatic change-over switch is covered with the fixed panel, and the two panels are each provided with one opening; when the sliding panel moves to a first station, the two openings do not coincide, a user cannot operate the automatic change-over switch, and the automatic change-over switch is in an automatic running state; when the sliding panel moves to a second station and the two openings coincide, the automatic running state is removed, and the user can stretch into the automatic change-over switch through a tool and rotate a transmission mechanism, thereby manually operating the automatic change-over switch; when the sliding panel moves to a third station and the two openings do not coincide, it is guaranteed that breakers on two sides are each in a switched-off state, a limiting mechanism on a motor shaft and a limiting mechanism on the sliding panel limit rotation of the motor shaft, and it is guaranteed that the automatic change-over switch cannot be switched on during outage and maintenance, it is guaranteed that maintenance is carried out safely, accidents are avoided, and manual and automatic orderly switching management is achieved.

The invention relates to a piezo injector with an actuator chamber (170), in which a piezo actuator (180) is arranged. The piezo injector comprises an upper section, the injector body (150) and a lower section, the nozzle body (140). The piezo injector also has a control piston bore (200), which is formed in the nozzle body, wherein a control sleeve (220), in which a control piston (340) is received, is arranged in the control piston bore (200). The control sleeve (220) seals against an intermediate plate (260) with a first front face (240) facing the piezo actuator (180). The control piston (340) has a first side (360) facing the piezo actuator (180), wherein the first front face (360) of the control piston (340) and the section of the control sleeve (220) facing the piezo actuator (180) form a first control chamber (380).

The embodiment of the invention discloses a method, a device and a system for remote procedure call control. The realization of the method comprises that a remote procedure call request transmitted by a client is received; the remote procedure call request is processed; if the time for processing the remote procedure call request reaches a preset value, the transport layer session of the remote procedure call request is transmitted through the client and activity notification information is transmitted to the client; and the preset value is less than the value of the overtime period of the transport layer session. By adopting the implementation method, after the remote procedure call request is received and when the remote procedure call request is processed, the processing time is timed and information is transmitted through the transport layer session of a session link between the client and a server within the preset time to ensure that the transport layer session of the session link is not closed because of overtime, thereby improving the session stability.

The invention discloses a structure and a method for preventing a mobile terminal protective jacket from being turned over and turning a screen off. A Hall inductive switch is arranged on one side inside a mobile terminal body; an induced magnet is embedded at a position on one side, which is opposite to the position of the Hall inductive switch on one side inside the mobile terminal body, inside a protective jacket cover body; a tinplate is jointed to the upper part of the induced magnet embedded into the protective jacket cover body. When the surface of a mobile terminal screen is covered by the mobile terminal protective jacket, the Hall inductive switch inside the mobile terminal body can be triggered by the induced magnet without being influenced by the tinplate. When the mobile terminal protective jacket is turned over to the back side of a mobile terminal, the tinplate is positioned between the Hall inductive switch and the induced magnet, and the Gaussian value of the SN pole of the induced magnet is tilted by using the magnetic conduction characteristic of the tinplate, so that the magnetic induction intensity on the Hall inductive switch is changed. The Hall inductive switch is not turned off when the mobile terminal protective jacket is turned over to the back side of the mobile terminal, so that the mobile terminal screen is prevented from being turned off, and normal use of a user is ensured.
