Abstract: This paper describes an invention involving an electrochemical discharge-enabled micro-grinding process for micro-components of silicon-based materials. The specific machining method is described below. A micro-grinding tool and an auxiliary electrode are respectively connected to the negative and positive electrodes of a pulsed DC power supply. When the current flows through the loop, an electrochemical hydrogen evolution reaction (HER) occurs at the micro-grinding tool in the grinding fluid, which generate multiple hydrogen bubbles. The bubbles coalesce into an insulating gas film and separate the micro-grinding tool from the grinding fluid; when the critical voltage is reached, the gas film is broken down and an electrochemical discharge occurs accompanied by discharge spark; under the action of the discharge spark, the surface material of the workpiece in the discharge-affected region is directly ablated to generate a heat-affected layer (HAL), namely, physical modification.

Abstract: A method for igniting a refillable gas lighter comprises a rear case, a front case and a barrel. The lighter is provided with a physical phenomenon of piezo-electric effect to generate the electric spark. Inside the rear case, the pusher is pressed down to the gas tank with the pusher having a plurality of conducting strips that acts as an electrical conductor connected to the gas tank. A copper wire carrying negative charge is connected with a bridge plate that passes through the conductive hose to achieve fuel distribution and electric conduction. The conductive hose transfers the igniting gas from the gas tank to the spark plug, where the ignition initiates the flame. The housing assembly includes a rear case with a rear case neck, a front case with a front case neck, and a barrel. The housing assembly is further locked together by means of a barrel sleeve where the barrel has a flame opening to ignite.

Abstract: A piezoelectric lighter includes a lighter housing having a liquefied gas storage, a gas emitting nozzle extended from the liquefied gas storage, a piezoelectric unit disposed in the lighter housing, and a lighter cap slidably coupled on top of the lighter housing above the piezoelectric unit. The gas emitting nozzle is slidably received at a nozzle window of the lighter cap, wherein an exit opening of the gas emitting nozzle is embedded in the ceiling of the lighter cap to protect the exit opening of the gas emitting nozzle. When the lighter cap is depressed to expose the exit opening of the gas emitting nozzle above the ceiling of the lighter cap, the piezoelectric unit is depressed and the gas emission unit is actuated at the same time to produce a flame at the exit opening of the gas emitting nozzle.
