The invention provides a separated gate type flash memory for sharing a word line. The flash memory comprises a semiconductor substrate provided with a source electrode region and a drain electrode region which are arranged at intervals, a word line arranged between the source electrode region and the drain electrode region, a first storage bit unit positioned between the word line and the source electrode region, and a second storage bit unit positioned between the word line and the drain electrode region, wherein, the two storage bit units are separated by a tunnel oxide from the word line; one storage bit unit is provided with a first control gate and a first floating gate, and the other storage bit unit is provided with a second control gate and a second floating gate; and the two control gates are arranged at intervals on the two floating gates respectively. The separated gate type flash memory for sharing the word line can effectively reduce the area of a chip while ensuring that the chip retains the electrical isolation performance, and avoid the phenomenon of over-erasure at the same time.

A magnetic read / write apparatus comprises: a recording medium; and a head for writing / reading data to / from each sector on the recording medium; wherein the magnetic read / write apparatus further comprises: a write inhibit slice setting circuit for, when data is written to the recording medium, setting a write inhibit slice for each sector based on the recording state of each sector on the recording medium.

A magnetic recording medium having a first magnetic layer, a spacer layer, and a second magnetic layer, in this order, wherein the spacer layer includes a non-magnetic layer and a thickness of the spacer layer is selected to establish anti-ferromagnetic coupling between the first magnetic layer and the second magnetic layer, and a thickness of both the first and second magnetic layers are less than a critical thickness for formation of stripe domains in the magnetic layers is disclosed.

The present invention provides a recording apparatus having a recorder that records information signals pertaining to broadcast programs received from a receiver onto a recording medium, a setting device that sets a repetitive recording reservation program specifying recording of a broadcast program at each predetermined time interval, and a controller that determines whether or not information signals previously recorded onto the recording medium in accordance with the repetitive recording reservation program have already been reproduced by a reproduction device, and if so causes the recorder to erase the previously recorded information signals and records information signals of a current broadcast, and if not causes the recorder to record the information signals of the current program without erasing the previously recorded information signals.

Embodiments of the invention provide a memory erasing method and apparatus. The method comprises: receiving an erasing check command sent by an upper computer, wherein the erasing check command comprises target file information; determining a target region by using the target file information, wherein the target area comprises target data; checking the target data according to a preset check rule, to obtain a check result; obtaining, by the upper computer, the check result, and determining, by using the check result, whether the target area is to be erased, if yes, generating, by the upper computer, an erasing command; receiving the erasing command sent by the upper computer; and erasing the target area by using the erasing command. The embodiments of the present invention are used to reduce time overheads for erasing the memory and increase a service life of the memory.

The method forms a liquid-repellent film on a surface of a nozzle plate having nozzle apertures through which droplets of liquid are ejected. The method includes: a termination process step of carrying out a hydrogen termination process or a halogen termination process on a surface of a nozzle plate, at least a portion of the surface of the nozzle plate being made of a material containing silicon; and a liquid-repellent film formation step of forming a liquid-repellent film on the surface of the nozzle plate after the termination process step by bringing a liquid-repellent film raw material into contact with the surface of the nozzle plate while applying energy to the surface. Each molecule constituting the liquid-repellent film raw material has an unsaturated carbon bond at an end and has a liquid-repellent functional group. The liquid-repellent film is bonded to the surface of the nozzle plate through silicon-carbon bonds.

An electronic defrost timer for a mechanical refrigerator is disclosed, which includes an input unit applying its power to the defrost timer and receiving an input of time for controlling the defrost timer, a control unit controlling a compression mode or a defrost mode by using the input time and a program, and an output unit directly controlling the compression mode or the defrost mode under the control of the control unit. According to the electronic defrost timer, since the input unit, the control unit, and the output unit are mounted on a PCB and the compression mode or the defrost mode is controlled by the program, the compression / defrost operation time of the refrigerator can be promptly controlled by a simple modification of the program, without any modification of moldings, and thus the manufacturing cost and time can be saved.
