A system of controlling a sliding member for a vehicle includes a motor, a pulse generating device, a counting device and a control device. The system has a range for movement of the sliding member between a position short of a first lock position and a position short of a second lock position. Also, the system has an error range within the range for movement of the sliding member and memorizes in advance a range of pulse count representative of the error range. If a pulse count counted by the counting device falls within the range of pulse count when the sliding member discontinues movement due to detection of an overload of the motor, the system resets a pulse count counted by the counting device at one of the first and second lock positions.

A pump for an inkjet printer applying a negative pressure to an inkjet head nozzle, includes: a tube connected to the inkjet head nozzle and being U-shaped; a plurality of rollers which contact an inner arch of the tube and having a tapered shape; and a rotor to which the plurality of rollers are rotatably mounted. When the rotor rotates in a direction, at least one of the plurality of rollers rotate and squeeze the tube. When the rotor stops rotating, the plurality of rollers return to a state in which the plurality of rollers do not squeeze the tube due to a recovering force of the tube. The squeezing of the tube generates the negative pressure in the inkjet head nozzle.

The valve rocker for the automobile engine is not prone to abrasion, long in service life and low in noise and makes contact with the valve lifter all the time.

The invention discloses a construction lifter control system, and relates to the field of lifter control systems. According to the construction lifter control system, the control operation mode of a lifter is switched into a manual operation mode or an automatic operation mode through an electric lock switch, and the lifter is controlled to operate to any height of a floor; and logical judgment isconducted through a PLC to obtain whether the lifter is on a flat layer or not, and thus a lifter door and a floor door are controlled to be opened or closed. According to the construction lifter control system, the construction lifter can parked at any height, and meanwhile, collision noise caused by the use of a mechanical lock and a car cam is avoided.

An automatic positioning finding structure with a furniture pulling device comprises the pulling device sliding in an inner cavity of a fixed groove piece. The pulling device at least comprises a support assembly. A pulling part is arranged on the support assembly. A supporting boss is arranged on the fixed groove piece. A supporting wing part is arranged on the support assembly and slidingly supported on the supporting boss. An elastic part and a fixed part are arranged on the support assembly. The elastic part slidingly and elastically acts on the top and/or the side of the inner cavity of the fixed groove piece. The fixed part has a limiting effect on the fixed groove piece at least after the pulling device completes positioning finding so that the supporting wing part can be closely pressed on the supporting boss so as to lock and fix the pulling device. Through the improvement of the structure, the automatic positioning finding structure has the advantages of being simple and reasonable in structure, reliable in performance, rapid and convenient to detach and assemble, convenient to use and high in universality and practicability.

The invention discloses a hot pot capable of achieving liquid level lifting, belongs to the technical field of hot pots, and solves the technical problem that in the prior art, a material tray must be matched with a specific stockpot for use and cannot be suitable for stockpots of other sizes. The hot pot comprises a stockpot and a material tray arranged in the stockpot, the material tray divides the stockpot into an upper space for containing food materials and a lower space for containing soup, the material tray is provided with a breathing cavity with an open lower end, at least part of the breathing cavity is located in the lower space to contain part of the soup, the breathing cavity is communicated with the lower space, and a liquid through hole is formed in the part, surrounding the periphery of the breathing cavity, of the material tray.

The present invention relates to a device for varying a stroke of a clutch pedal. More particularly, the present invention relates to a device for varying a stroke of a clutch pedal applied to a pedal unit of a clutch system of a manual transmission and varying an effective stroke of a clutch pedal depending on a vehicle speed signal and an engine RPM signal thereby preventing energy collision noise of a driving system.

The invention provides an indoor unit foam installation structure and an air conditioner. The indoor unit foam installation structure comprises a shell and a first foam assembly, wherein the first foam assembly is arranged in the shell, a second foam assembly is installed on the rear side of the first foam assembly, and the front side of the second foam assembly abuts against the rear side of the first foam assembly. By arranging the first foam assembly, it is avoided that cold air blown out of an air outlet is directly blown to a top cover plate in a refrigeration state, and condensation on the top cover plate is prevented. By arranging the second foam assembly, it is avoided that evaporator fins scratch other parts, and it is also avoided that collision noise between an evaporator connecting pipe and the shell is caused by vibration in the use process of the air conditioner. As the front end of the second foam assembly abuts against the rear end of the first foam assembly, the rear side of the first foam assembly and the front end of the second foam assembly are limited and fixed, the stability of the whole foam installation structure is guaranteed, assembly dislocation between parts is avoided, and a fool-proof effect is achieved.

A brake amplifier having a housing; a spindle nut; a motor; two tie rods; a hook frame; and a pressure piston which can be coupled at a first end to a brake pedal and at a second end to a brake master cylinder. A return spring is assigned to the pressure piston which bears a follower element at the second end, which follower element engages the hook frame at the rear and rests on the end side of the spindle nut in a rest position by means of a distance holder passing through the hook frame such that the follower element is spaced apart from the hook frame. In the operating position, the pressure piston is moved relative to the main shaft so that the follower element is spaced from the hook frame and is spaced from the end side by means of the distance holder. An elastomer element projecting axially in the direction of the hook frame is arranged on the side of the follower element facing the hook frame, and/or an elastomer element projecting axially in the direction of the follower element is arranged on the end side of the hook frame facing the follower element.
