A sputtering target contains high purity Nb of which Ta content is 3000 ppm or less and oxygen content is 200 ppm or less. Dispersion of the Ta content in all the sputtering target is within ±30% as a whole target. Dispersion of the oxygen content is within ±80% as a whole target. According to such sputtering target, an interconnection film of low resistivity can be realized. In addition, each grain of Nb in the sputtering target has a grain diameter in the range of 0.1 to 10 times an average grain diameter and ratios of grain sizes of adjacent grains are in the range of 0.1 to 10. According to such sputtering target, giant dust can be largely suppressed from occurring. The sputtering target is suitable for forming a Nb film as liner material of an Al interconnection.

When recording is performed by focusing a short pulse laser on an inside of a transparent medium such as quartz glass, and forming a minute deformed region in which the refractive index is different from that of surroundings thereof, it is difficult to ensure a recording quality.Therefore, a recorded dot length in a depth direction is monitored and a power of the laser light is adjusted based on the monitored recorded dot length, or a difference between a focus position where a region of the recorded dots appears brighter than the surroundings and a focus position where the region of the recorded dots appears darker than the surroundings is measured and the power of the laser light is adjusted based on the difference.

An image forming apparatus includes a main body portion including an image carrier, an image-carrier driving unit, a latent-image forming unit, a developing-unit attachment section, and a transfer-unit attachment section. The developing-unit attachment section receives a first developing unit having plural developing members or a second developing unit having a single developing member. The transfer-unit attachment section receives a first transfer unit, which includes a first transfer member capable of retaining a recording medium and a first transfer driving unit that rotates the first transfer member, and a second transfer unit, which includes a second transfer member that cannot retain the recording medium. When the first developing unit and the first transfer unit are attached to the developing-unit attachment section and the transfer-unit attachment section, respectively, the first transfer driving unit is mechanically connected to the first developing unit.

A recording medium and apparatus enable the number of data units of recording pulse information to be reduced. The recording medium includes an information area for recording set values of a recording pulse for forming recording marks. The set values include preceding space-based set values having a first reference value as a set value of a recording pulse corresponding to a predetermined preceding space and a first difference set value of a recording pulse corresponding to a space other than the predetermined preceding space; and trailing space-based set values having a second reference value as a set value of a recording pulse corresponding to a predetermined trailing space and a second difference set value of a recording pulse corresponding to a space other than the predetermined trailing space and which is expressed as a difference from the second reference value.

In write power adjustment for an optical disc having a plurality of information storage layers, data of trial writing is varied by the influence of layers other than a target layer. It is difficult, therefore, to determine optimal write power. A modulation M[m] is obtained from a reproduction signal amplitude of a signal subjected to the trial writing performed with use of write powers Pw[m] (m being an integer) of a plurality of kinds. At least an optimum write power intercept Pint_opt is determined by fitting a relation between the Pw[m] and the M[m] by a modulation characteristic formula M=Masy×(1−(Pint−Pasy)/(Pw−Pasy)) having an asymptotic modulation Masy, a write power intercept Pint, and an asymptotic write power Pasy as parameters. Approximation accuracy by the fitting and/or quality of the trial writing signal are evaluated with use of at least the M[m], the modulation characteristic formula, and the Pint_opt. An optimum write power Pw_opt is calculated by performing a specified operation at least with use of the Pint_opt.

A piston is provided in which the amount of uncombusted and discharged air-fuel mixture is small, and agglutination of a piston ring due to heat is prevented.In a piston 2 in which plural peripheral grooves in which piston rings are provided are formed in an outer peripheral surface, as the relation between an inner diameter B of a cylinder 1 and a distance L between an upper surface of the piston and an upper surface of a top peripheral groove 4a, L/B≦0.1 holds. A cooling chamber 5a is formed in close vicinity to the top peripheral groove. A dead volume S partitioned with the piston, a cylinder liner 11 and a top piston ring 3a is reduced, and the amount of air-fuel mixture enclosed here and discharged in uncombusted state is reduced. Further, agglutination of the top piston ring to the cylinder due to thermal load can be prevented with the cooling chamber 5a. The thermal efficiency as an engine is improved in comparison with conventional art.

The present invention provides a recording medium and a recording/reproducing apparatus which enable the number of data units of recording pulse information to be reduced by dividing the recording pulse information into 1 byte-parameter information and differences from a value thereof, and the recording pulse information to be recorded on an existing DI area.A recording medium (801) has an information area (101) in which is recorded, as recording/reproducing control information, set values of a recording pulse adopted when forming a recording mark including: preceding space-based set values that include a first reference value that is a set value of a recording pulse corresponding to a predetermined preceding space and a first difference set value which is a set value of a recording pulse corresponding to a space other than the predetermined preceding space and which is expressed as a difference from the first reference value; and trailing space-based set values that include a second reference value that is a set value of a recording pulse corresponding to a predetermined trailing space and a second difference set value which is a set value of a recording pulse corresponding to a space other than the predetermined trailing space and which is expressed as a difference from the second reference value.

An electrode active material mainly includes an organic compound having, in a structural unit thereof, a conjugated diamine structure represented by the general formula (I), and an electrolyte includes a carbonate ester compound represented by the general formula (II). In the formulae, R1 to R4 represent substituted or unsubstituted alkyl groups, or the like, whereas X1 to X4 represent a hydrogen atom or a substituent. A secondary battery is achieved which has a high energy density and thus produces a high output, and has favorable cycle characteristics with a small capacity degradation even in the case of repeating charge and discharge.
