Abstract: The present invention relates to an ultrahigh sensitive pressure-sensing film based on spiky hollow carbon spheres and the fabrication method thereof. The fabricated spiky hollow carbon spheres composed polydimethylsiloxane sensing film whose spheres were well dispersed in the matrix. The spiky structure is useful for the spheres to trigger Fowler-Nordheim (F-N) tunneling effect and thus enhancing the sensitivity of the material. The carbon material fabricated by the precursor transformation method contains a proper Nitrogen doping, which has efficiently increased the carrier migration ability. The hollow structure can both regulate the density of fillers and help to improve its temperature independence. Calcine the spheres under an inert atmosphere to transform the spiky hollow organic spheres into a carbon one, in this process the Nitrogen fraction and graphitization can be adjusted. The above carbon spheres then can be assembled with polydimethylsiloxane to achieve the composite film.

Abstract: A remote control controls a karaoke device to select songs. The remote control stores a controller identifier, obtains a user unique code and control instructions input by a song selector, and combines the controller identifier, the user unique code, and each of the control instructions into a controlling message. The remote control transmits the controlling messages to the karaoke device to enable the karaoke device to collectively display the songs selected by the song selector and the user unique code corresponding to the song selector.

Abstract: A remote control system for a multi-screen display of an array of sub-displays tiled together contiguously includes a remote controller and a number of control boxes each of which is installed on a corresponding sub-display. The remote control is configured for receiving user input governing selection and control of the sub-displays, generating a control signal based upon the selection and the control of the sub-displays, and transmitting the control signal. Each control box is configured for receiving the control signal, identifying if the control signal is passed and transferred to a controller of corresponding sub-displays upon the selection of the sub-displays.

Abstract: A bathroom lock device includes an inner locking mechanism and a lock set. The inner locking mechanism includes a manual control rod, an unlocking rotary plate and an inner actuating rotary plate. The manual control rod has a rotatable wheel while the unlocking rotary plate has a pair of actuating protrusions. In a locking operation, the manual control rod is pressed to a locking position so as to limit a rotational movement of the inner actuating rotary plate. In an unlocking operation, the manual control rod is returned to an unlocking position by turning a lever so as to permit turning the inner actuating rotary plate. When the lever turns the unlocking rotary plate, the actuating protrusions of the unlocking rotary plate smoothly push the rotatable wheel of the manual control rod so as to return the manual control rod to the unlocking position.

Abstract: A door lock mechanism includes a rose escutcheon having a mounting plate and two positioning plates provided on a side thereof, a door handle rotatably extending through the rose escutcheon and the mounting plate, a spindle including a first end securely attached to the handle, and a return disc mounted to a second end of the spindle. The return disc includes an annular wall and a notch. A return spring is received in the annular wall and extends through the notch of the return disc, with two ends of the return spring being respectively attached to the positioning plates of the mounting plate of the rose escutcheon for returning the handle. Since the return spring is directly received in the annular wall of the return disc, a compact design is provided. The door lock mechanism further includes a restraining plate and a locking/unlocking control bar cooperating with the restraining plate.

Abstract: A lock assembly includes a fixing plate fixed to an inner side of a door. An inside rose liner is fixed to the fixing plate. A shaft is rotatably mounted in an axial hole of the fixing plate and coupled with a tail piece of an auxiliary lock body. An inside handle includes an inside spindle rotatably mounted in another axial hole of the fixing plate. A control mechanism includes a sliding plate slidably mounted in the inside rose liner, a driving wheel mounted on the inside spindle to turn therewith, and a driven wheel mounted on the shaft to turn therewith. Each of the driving wheel and the driven wheel includes at least one pressing section on an outer periphery thereof for pressing against an associated pressing portion of the sliding plate. The auxiliary lock is simultaneously unlatched when the inside handle is turned.

The latch assembly is mounted in a bore of a door by inserting the housing into the bore with the housing being mounted on the casing of the latch assembly.

Abstract: A bathroom lock device includes an inner lock assembly, an outer actuating wheel and a latch unit. The inner lock assembly is consisted of an actuating press rod, an unlocking cam and an inner actuating wheel, which constitutes a press-button mechanism. In locking operation, the actuating press rod is pressed to limit rotation of the outer actuating wheel and to rest in lock stage. In unlocking operation, an inner lever is operated to successively actuate the unlocking cam and the inner actuating wheel for rotation. Thus, the preceding rotation of the unlocking cam can push the actuating press rod to rest in unlock stage, and the following rotation of the inner actuating wheel can drive the latch unit for retraction.

Abstract: An apparatus joins bonding pads of a slider and lead pads of lead wires in a head gimbals assembly to improve efficiency, downsizing, and maintenance of solder-ball disposing devices, and solder-ball reflow devices for reflowing solder balls. The solder-ball disposing apparatus discharges solder balls from solder-ball discharging holes of a solder-ball feeder unit which are evacuated by a suction pad. An environmental space and an inert-gas supply portion for forming inactive atmosphere are formed on a table to eliminate an inert-gas supply unit from an optical unit, so that converged laser beams are directly radiated onto the solder balls.
