Abstract: A data erase method of a three dimensional (3D) memory device comprising the following steps. First, in a first phase of an erase operation, a first voltage is applied to a first semiconductor channel of the semiconductor channels to erase data stored in the memory cells defined on the first semiconductor channel and a second voltage is applied to a second semiconductor channel of the semiconductor channels, wherein the second semiconductor channel is adjacent to the first semiconductor channel. Then, in a second phase of the erase operation, the second voltage is applied to the first semiconductor channel and the first voltage is applied to the second semiconductor channel.

Abstract: A adjustable wrench comprises a body used to operate the adjustable wrench including a fixed jaw extending outward therefrom and having a holder mounted on a top end thereof, including an arcuate recess fixed on a middle portion of a front side thereof; a movable jaw pivoted in the holder, serving as engaging a workpiece, and including a guiding rib relative to the arcuate recess extending from a bottom end thereof to be adjusted and moved along the arcuate recess; a locking mechanism axially displacing in the cavity of the body and including a control unit to operate the locking mechanism and to drive a pushing member, the control unit including locking and unlocking positions so as to move the pushing member across the notch of the arcuate recess and then to bias against the guiding rib, thereafter, the pushing member is driven to move downward, thus disengaging the guiding rib to slide freely.

Abstract: A special tool used in a control arm of vehicles comprises a rod to be held by hand formed in an elongated stick shape and including a lower end having a retaining portion to abut against a bottom side of the control arm, and between the rod and the retaining portion being defined a support portion; a suspending seat including a lateral slot secured at a side thereof to engage with the support portion; an engaging member connected to the suspending seat so as to hook the control arm of vehicle.

Abstract: An adjustable pry bar comprises a prying block used to pry and remove an object and including first and second side wings mounted on a rear end thereof and parallel to each other to clamp a head end of a handle, the first side wing including a groove to receive multiple balls and biasing members; an adjusting mechanism installed in a central aperture and a notch of the head end and including a plurality of biasing members and balls, a shaft member, and a control member, the biasing member being flexible to be pushed backward to abut against the balls, the shaft member including a first end for engagement with the balls, the first end including a recess arranged around an outer rim thereof, the shaft member also including a second end extending out of a second through hole of the second side wing to coupled with the control member.

Abstract: A adjustable pliers comprises a body used to operate the movable pliers including a fixed jaw extending outward therefrom and having a holder mounted on a top end thereof, including an arcuate recess fixed on a middle portion of a front side thereof; a movable jaw pivoted in the holder, serving as engaging a workpiece, and including a guiding rib relative to the arcuate recess extending from a bottom end thereof to be adjusted and moved along the arcuate recess; a locking mechanism pivoted in the cavity of the body and including a control unit to operate the locking mechanism and to drive a pushing member, the control unit including locking and unlocking positions so as to move across the notch of the arcuate recess and then to bias against the guiding rib, thereafter, the pushing member is driven to move downward, thus disengaging the guiding rib to slide freely.

Abstract: A forced puller includes a central seat having a threaded hole centrally defined therein and extending therethrough. The central seat has two opposite sides each having a rod perpendicularly extending therefrom relative to an axis of the threaded hole. Two hook members are respectively slidably mounted to a corresponding one of the two rods. Each hook member is formed with a hook engaged to a workpiece that is purposed to be detached. A main threaded rod is screwed through the threaded hole in the central seat. The main threaded rod has a polygonal head formed on a first end thereof for user to forcefully rotate the main threaded rod and a push portion is formed on a second end of the main threaded rod to securely and longitudinally abut against the workpiece after rotating the main threaded rod.

Abstract: An oil filter wrench in accordance with the present invention comprises a first handle and a second handle pivotally jointed together by a pivot shaft. A first jaw and a second jaw are respectively pivotally connected to a front end of the first handle and the second handle. The angle formed by the first/second handle and the first/second jaw can be adjusted step by step.

Abstract: A device for adjusting the exposure of an image sensor includes an average luminance value calculation unit, a first exposure control unit and a correction exposure value calculation unit. The average luminance value calculation unit calculates the first total average luminance value of pixels that are output from the image sensor. The first exposure control unit controls the exposure value of the image sensor based on a previously set exposure value. The correction exposure value calculation unit calculates a correction exposure value by multiplying the exposure value, which is previously set on the first exposure control unit, by the ratio of a target luminance value to the first total average luminance value. Additionally, the first exposure control unit receives the correction exposure value from the correction exposure value calculation unit and controls the exposure value of the image sensor based on the correction exposure value.

Abstract: In an interferometric device using a coherent beam and an image pickup camera, a protective glass for the detector surface is needed on the incident side of the pickup unit of the image pickup camera, and this gives rise to interference fringes which constitute noise. To solve this problem, a dustproof container is configured also to cover an imaging lens system arranged on the incident side of the pickup unit of the image pickup camera, and the pickup unit of the image pickup camera is arranged in this container. By assigning the function of the protective glass for the detector surface in the conventional configuration to the imaging lens system, the protective glass is made unnecessary.

Abstract: Methods and apparatus are disclosed for reducing output ripple voltages in bandgap voltage reference circuits. Ripple rejection circuitry is connected to a supply voltage and a first control signal, such as from an amplifier. The ripple rejection circuitry provides a second control signal representative of a difference between the supply voltage and the first control signal. The second control signal is then used to generate a reference voltage output. The incorporation of the supply voltage component in the second control signal operates to reduce or suppress the effects of power supply ripple on the bandgap voltage output.

Abstract: A waveguide is provided with coplanar printed probes that enable the waveguide to have reduced volume and enhanced signal processing ability. The waveguide includes a cup-shaped tube portion, a body portion behind the tube portion, and a circuit board for receiving and processing wave signals. The circuit board is provided at one side facing away from the tube portion with two printed probes that are perpendicular to and spaced from each other by a predetermined distance. And, the tube portion is provided at a position facing one of the two printed probes that is located farther from the tube portion with a guide slot, so that wave could be guided into the guide slot and received by the printed probe facing the guide slot.
