Abstract:
A jet propulsion construction toy assembly includes a container mounted on a movable brick assembly. A launching unit includes a launching seat permitting extension of a nozzle of the container thereinto and having an inlet. When the nozzle extends into the launching seat, an actuator mounted movably in said launching seat is operable to engage the nozzle such that said container is filled with fluid including air and liquid and pumped out of a barrel by a pump through first and second conduits, the inlet and the nozzle. Thereafter, when the nozzle is released from the launching seat due to disengagement between the nozzle and the actuator, jet of the fluid from the container through the nozzle forms a propulsion force to drive movement of a combination of the brick assembly and the container away from the launching unit.
Abstract:
A data programming circuit for storing a writing data into a memory cell is provided. The data programming circuit includes a control circuit and a current generating circuit. The control circuit generates a control signal according to the writing data. The current generating circuit provides a writing current to the memory cell to change a crystalline state of the memory cell. The writing current has a pulse width corresponding to the writing data, and the crystalline state corresponds to the writing data.
Abstract:
A voltage compensation circuit, a multi-level memory device with the same, and a voltage compensation method for reading the multi-level memory device are provided. When a memory cell is read, a reference voltage applied to the memory device is adjusted according to variation of characteristics of a drift resistance of a reference cell. The increased value of the reference voltage (i.e. a voltage difference) corresponds to a resistance variation caused by a drift condition. The drift compensation mechanism is adaptive to a compensation circuit of a read driver of the memory device, which can compensate variation of the voltage level when data is read from the memory cell. When the resistance drift occurs, a drift amount is calculated and is added to the reference voltage, in order to avoid the error in judgement caused by the resistance drift when the stored data is read out.
Abstract:
A staple gun with a safety device and its safety device are disclosed. The staple gun with a safety device comprises a safety device and a staple-floating unit that are installed in a housing of the staple gun. The safety device includes a safety push sheet and a switch. In a middle portion of the safety push sheet is defined an engaging slot along a staple-discharging direction, and the safety push sheet is further provided with a triggering sheet extending from an upper end thereof. The staple-floating unit is movably connected to the safety device and includes a guide sheet, a control knob, and a positioning pin. The positioning pin can be used to drive the safety push sheet and the guide sheet to move downwards to make the safety push sheet and the guide sheet to protrude out of the staple exit synchronously for facilitating exerting the staple-floating function.

Abstract:
Devices controlling a phase change storage element and methods for increasing reliability of a phase change storage element. The invention introduces a first operation mode and a second operation mode. A reference phase change storage element is forced a write current for an ideal conduction period in the first operation mode. In the second operation mode, the invention generates a proper conduction period based on the resistance of the reference phase change storage element, and forces the write current into the controlled phase change storage element for the proper conduction period.
Abstract:
A phase change memory wherein several phase change storage elements are coupled in series to share a single current source. The current provided by the current source is directed by a plurality of switches. To write/read the phase change storage elements, the invention provides techniques to control the current value generated by the current source and controls the states of the switches. The impedance summation of the phase change storage elements vary with the data stored therein.
Abstract:
A verification circuit for a phase change memory array is provided. A sensing unit senses a sensing voltage from a memory cell of the phase change memory array according to an enable signal. A comparator generates a comparing signal according to the sensing voltage and a reference voltage, so as to indicate whether the memory cell is in a reset state. A control unit generates a control signal according to the enable signal. An operating unit generates a first signal according to the control signal, so as to indicate whether the comparator is active. An adjustment unit provides a writing current to the cell, and increases the writing current according to the control signal until the comparing signal indicates that the memory cell is in a reset state
Abstract:
A memory having a memory cell, a resistance estimator and a write current generator. The resistance estimator is coupled to the memory cell to estimate the resistance of the memory cell and outputs an estimated resistance level. According to the estimated resistance level, the write current generator generates a write current to flow through the memory cell and to change the resistance of the memory cell. The write current is in a pulse form, and the write current generator sets the pulse width, or magnitude, or both the pulse width and the magnitude of the write current according to the estimated resistance level.
