An optical film that is excellent not only in transparency and heat resistance but also in solubility in an organic solvent and linear thermal expansion coefficient. Also, a product or a member which meets high demands for heat resistance and low linear thermal expansion coefficient with the use of the optical film, more specifically a transparent substrate using the optical film, and an image display device and a solar cell including the optical film or the transparent substrate. The optical film contains a polyimide having a specific structure in which a repeating unit of a chain of a polymer has both an amide group and an imide group and the polymer has a fluorine atom. The polyimide is obtained by mixing a dehydrating agent and an imidizing agent with a polyamic acid solution so as to imidize the polyamic acid.

The present invention provides a semiconductor integrated circuit device equipped with a memory circuit, which realizes speeding up of its operation in a simple configuration or realizes high reliability and enhancement of product yields in a simple configuration. A memory cell is selected from within a memory array having a plurality of memory cells by a selector or selection circuit. MOSFETs constituting a precharge circuit provided for signal lines for transferring a read signal therefrom to a main amplifier are respectively brought to an on state based on a memory cell select start signal transferred to the selection circuit and brought to an off state prior to the transfer of the read signal from the memory cell to thereby complete precharging, whereby NBTI degradation at standby is avoided.

Several embodiments of induction systems for internal combustion engines wherein each chamber of the engine is served by a relatively long low speed induction passage and a relatively short high speed induction passage. The arrangements of the passages is such that the change in length is achieved quite simply by positioning a throttle valve at the upstream end of the short induction passage and having both passages communicate with an air inlet device. Several embodiments of throttle valve arrangements are also disclosed wherein a single throttle valve can control the flow through two adjacent induction passages.

A semiconductor integrated circuit device including a memory circuit with both high access efficiency and high memory efficiency in a simple configuration is provided. In a memory read control circuit, burst length is changed based on whether or not a read instruction is issued at a cycle after a cycle at which a read instruction /R is issued. And, in a memory write control circuit, burst length is changed based on whether or not a write instruction is issued at a cycle before a cycle at which a write instruction /W is issued.

A Y selection line for write for controlling operations of a column selection switch within a write amplifier and a Y selection line for read for controlling operations of a column selection switch within a read amplifier are provided individually and the column selection switch within the read amplifier is set to the non-operating condition during the write operation. Accordingly, a through-current during the write operation may be reduced. In this case, the write IO line and read IO line are allocated crossing sense amplifier columns, while the column selection line for write and column selection line for read are allocated in parallel to the sense amplifier columns.
