摘要:
In a synchronous semiconductor memory device, memory arrays (MA) forming activation units each are divided into a plurality of small memory arrays (MK). There are provided local I/O line pairs (LIO) each for two small memory arrays. The global I/O line pairs (GIO) crossing word lines are arranged in word line shunt regions (WS). The connection switches (BS) are arranged in the crossing between the local I/O line pairs and global I/O line pairs. Each small memory array in the activated memory array is connected to the corresponding global I/O line pair through the local I/O line pair. Thereby, a plurality of bits can be simultaneously read without increasing an area occupied by interconnections. The control of connection switch is made using a sense amplifier activation signal. Global I/O lines are precharged/equalized after data are transferred to read data registers provided for data output terminal for sequential data output or into selected memory cells. External clock signal is frequency-divided to produce phase-shifted internal clock signals which are used for producing internal voltage through charge operation.

摘要:
An internal clock signal generating circuit includes a selector, a delay line, a 2-frequency divider, a phase comparator and a shift register. The selector alternately selects an external clock signal and an internal clock signal output from the delay line and outputs the selected signal to the delay line. The delay line receiving the signal delays the external clock signal, and delays the internal clock signal output from itself. The 2-frequency divider divides frequency of the internal clock signal by 2. Phase comparator compares phases of the external clock signal and the output signal from the 2-frequency divider. Delay time of the delay line is adjusted by the phase comparator and the shift register so that the phase difference is made 0.

A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (θ1) is set in a range of 5° to 15°, and a cap taper angle (θ2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.
摘要:
An entry including multiple bits of unit cells each storing data bit is coupled to a match line. The match line is supplied with a charging current having a restricted current value smaller than a match line current flowing in a one-bit miss state in one entry, but larger than a match line current flowing in an all-bit match state in one entry. A precharge voltage level of a match line is restricted to a voltage level of half a power supply voltage or smaller. Power consumption in a search cycle of a content addressable memory can be reduced, and a search operation speed can be increased.

The disclosure provides a control device of a spark-ignition gasoline engine. When an operating state of an engine body is within a low engine speed range, a controller operates a fuel pressure variable mechanism so that a fuel pressure is higher within a high engine load range compared to a low engine load range, the controller operates, within the high engine load range, a fuel injection mechanism to perform at least a fuel injection into the cylinder by a cylinder internal injection valve at a timing during a retard period from a late stage of a compression stroke to an early stage of an expansion stroke, and the controller operates, within the high engine load range, an ignition plug to ignite at a timing during the retard period and after the fuel injection.

The disclosure provides a control device of a spark-ignition gasoline engine. When an operating state of an engine body is within a low engine speed range, a controller controls a fuel pressure variable mechanism so that a fuel pressure is higher within a high engine load range compared to a low engine load range, the controller operates, within the high engine load range, a fuel injection valve to perform a fuel injection at least at a timing that is more retarded than an injection timing of a fuel within the low engine load range and is within a retard period from a late stage of a compression stroke to an early stage of an expansion stroke, and the controller operates, within the high engine load range, an ignition plug to ignite at a timing within the retard period and further after the fuel injection.

A cantilever has a probe portion and a cantilever portion having a free end portion from which the probe portion extends. A displacement detecting portion detects a displacement of the cantilever portion according to an interaction between a sample and the probe portion. An electrode portion is connected to the displacement detecting portion. An insulation film is formed over at least one of the electrode portion and the displacement detecting portion. A functional coating in the form one of a conductive film, a magnetic film, and a film having a light intensity amplifying effect is disposed on the insulation film.

Provided is a self displacement sensing cantilever, including: a cantilever (4) that has a probe (2) at its tip and has a distal end portion (3) at its distal end; a displacement detecting portion (5) that is provided to the cantilever (4), for detecting a displacement of the cantilever (4); an electrode portion (6) that is connected to the displacement detecting portion (5) and is communicated with the distal end portion (3); and an insulation film (7) that is formed over at least one of the electrode portion (6) and the displacement detecting portion (5) of the cantilever (4), in which the insulation film (7) is applied a coating of an arbitrary functional material (8). As a result, measurement with a scanning probe microscope may be performed at the same time as projecting light.
摘要:
A scanning probe microscope has a probe needle and a control section that controls relative scanning movement between the probe needle and a surface of a sample in at least one direction parallel to the sample surface and controls relative movement between the probe needle and the sample surface in a direction perpendicular to the sample surface. A vibration source vibrates the probe needle at a vibrating frequency relative to the sample surface. An approach/separation drive section causes the probe needle to relatively approach to and separate from the sample surface at a predetermined distance while the probe needle is vibrated at the vibrating frequency relative to the sample surface by the vibration source. A detection section detects a rate of change in a vibration state of the probe needle in accordance with a distance between the probe needle and the sample surface. An observation section gathers observation data from the sample surface when the rate of change in the vibration state of the probe needle detected by the detection section has exceeded a preselected threshold value.
