A copolymer is provided for use in a lithographic photoresist composition, particularly a chemical amplification photoresist. In a preferred embodiment, the copolymer is substantially transparent to deep ultraviolet radiation, i.e., radiation of a wavelength less than 250 nm, including 157 nm, 193 nm and 248 nm radiation, and has improved sensitivity and resolution. In one embodiment, the copolymer is comprised of an α-cyano- or an α-trifluoro-methacrylate monomer unit and a vinyl ether monomer unit. A lithographic photoresist composition containing the fluorinated copolymer is also provided, as is a process for using the composition to generate resist images on a substrate, i.e., in the manufacture of integrated circuits or the like.

A nonvolatile semiconductor memory device includes a nonvolatile storage element to which data is inhibited from being rewritten, a read operation control circuit which captures a read operation instruction signal in synchronization with an external input clock, and a write operation control circuit to which a write operation instruction signal is input asynchronously with the external input clock. The read operation instruction signal gives an instruction to start a read operation to read data out of the nonvolatile storage element, and the write operation instruction signal gives an instruction to start a write operation to write data to the nonvolatile storage element. The device further includes a reset circuit which resets an operation of the read operation control circuit upon receiving the write operation instruction signal.

An image forming device is disclosed that can control image blurring, image contraction, and the like when resilient transfer media such as cardboard is to be transported upward from a pair of resist rollers and guided to a transfer position, and obtain a suitable transfer image. Transfer media is transported upward by resist rollers, and guided toward a transfer position by a pair of guide plates. Because tip of a resilient transfer medium such as cardboard may spring back to its original shape after it separates from the resist rollers, one guide plate is urged toward the transfer position by spring members, and can absorb the springing of the transfer media back to its original shape by pivoting away from the transfer position, and thus can reduce the occurrences of image blurring or the like.

A portable electronic apparatus includes an acceleration detection unit, an evaluation-signal generation unit, and a control unit. The acceleration detection unit is configured to detect an acceleration generated in the portable electronic apparatus. The evaluation-signal generation unit is configured to carry out a predetermined process based on the acceleration detected by the acceleration detection unit in order to generate an evaluation signal representing the amplitude and positive or negative polarity of the acceleration. The control unit is configured to produce a result of determination as to whether or not the portable electronic apparatus has been driven to make a predetermined movement on the basis of the evaluation signal and carrying out a predetermined operation on the basis of the result of determination.

A contrast echo image of the myocardium and a cardiac chamber obtained by use of ultrasound diagnostic equipment is analyzed so as to determine the volume of blood within the myocardium. The contrast echo image is divided into a plurality of calculation regions, each being considered to have a uniform acoustic field intensity and covering a portion of a myocardium image region and a corresponding portion of a cardiac chamber image region. For each calculation region, a difference in intensity between the myocardium image region and the cardiac chamber image region is obtained, and the myocardium image region is colored in accordance with the difference.
