Abstract: Multiple displays are arranged such that their display surfaces are arrayed side by side. A measurement section measures orientation information about apparatus orientation. A control section determines the display surface a user is viewing from among multiple displays, based on the orientation information measured by the measurement section. The control section causes the display surface of displays, other than the display surface determined as being viewed by the user, to become darker than the display surface of the display determined as being viewed by the user.

Abstract: A novel polyimide resin is formed by imidizing a diamine component including an amide group-containing siloxane diamine compound represented by the following formula (1) and an acid dianhydride component including an aromatic acid dianhydride such as 3,3?,4,4?-diphenylsulfone tetracarboxylic dianhydride. This novel polyimide resin utilizes a novel polyimide resin into which a reaction group capable of reacting with a crosslinking agent to form a crosslinking point is pre-introduced before imidization. The novel polyimide resin can confer a comparatively low elastic modulus and heat resistance to a dry film or a photosensitive cover film formed from a photosensitive polyimide resin composition containing the novel polyimide resin. In the formula (1), R1 and R2 are each independently an optionally-substituted alkylene group, m denotes an integer of 1 to 30, and n denotes an integer of 0 to 20.

Abstract: A vehicle control unit includes interface software memory means storing an interface software program for connecting an application software program with an OS (operating system) in an internal ROM, a CPU (central processing unit) for performing computation for the application software program and the interface software program, a RAM (erasable memory) storing data such as the result of computation, an I/O unit for extending the control unit, and extending means for communicating memory data through a bus or a LAN. A single-chip micro-computer used in vehicle control permits an increase in input/output points or the addition of functionality, in which case an application software program can continue to be used simply by rewriting the interface software program, without further remanufacturing of the core unit.

Abstract: A polyimide compound has a low coefficient of linear thermal expansion comparable to the coefficient of linear thermal expansion of a conductor to be covered by the polyimide. The polyimide compound is less susceptible to contraction caused by dehydration process. The compound is obtained by the reaction of a highly linear acid dianhydride with a highly linear diamine and has a high imidization rate. Having a low coefficient of linear thermal expansion comparable to the conductor to be covered by the polyimide, the polyimide compound of the present invention is less susceptible to contraction that occurs during polyimide formation. The polyimide compound is suitable for making curl-free flexible wiring boards.

Abstract: Laser light irradiation can be performed on a recordable surface in a defocused state with a high-power laser beam with safety without incurring data destruction due to erroneous data recording or overwrite recording even in the recording on an eccentric disk or regardless of occurrence of wobbling of the disk surface. Laser irradiation is performed after moving an objective lens radially inwardly beyond a PCA located at an inner peripheral portion of the disk (or radially outwardly beyond the PCA located at an outer peripheral portion of the disk) by using a tracking coil.
