Abstract: Fingerprint-erasing cured films for rendering fingerprint depositions on various surfaces quickly less visible, or invisible; a manufacturing method therefor; a display or touch panel using the same; and electronic devices using these are provided. A liquid coating film including a solvent and a polymerizable resin composition curable by an activating energy beam is formed. In a state of the solvent being included within the film, the film is cured to form a cured film containing the solvent, preferably using a release material whose surface has undergone matte processing; and the solvent is evaporated in a subsequent drying step, whereby a cured film with a multitude of micropores on the surface is formed. Fingerprint soiling is rendered not readily visible or invisible. By using the cured film, there are obtained displays, touch panels, and electronic devices having fingerprint-erasability. To improve fingerprint-erasability, adding a water-absorbent compound to the film composition is preferable.

Abstract: Broadcast-receiving device has a broadcast-receiving section that receives a broadcast signal and generates an image signal on broadcast contents, an image-processing section that generates a menu signal for displaying a menu and generates an image display signal based on any one of the menu signal and the image signal, and a control section that controls operations of the broadcast-receiving section and the image-processing section. The control section chooses between an analog broadcast mode in which operations of the broadcast-receiving section and the image-processing section are controlled to be set in correspondence with the analog broadcast signal, and a digital broadcast mode in which operations of the broadcast-receiving section and the image-processing section are controlled to be set in correspondence with the digital broadcast signal. The control section controls the image-processing section to generate the menu signal corresponding to the chosen mode.

Abstract: An image signal display device includes a program data readout circuit by which at least one second adjustment data, not to be adjusted, takes a proper value relative to a first adjustment data, to be adjusted, in accordance with a predetermined relational expression. A data calculating circuit calculates the second adjustment data, and a data changing circuit changes the second adjustment data together with the first adjustment data. A memory stores coefficient data of the relational expression and a digital-to-analog convertor converts an output signal read out from the memory into an analog signal that is fed to a display device for display as an image.

Abstract: A video display apparatus capable of receiving multiple video input signals and of reducing its power consumption when each of those signals becomes inactive. Power consumption is reduced by selecting from a number of power saving modes. Each power saving mode has an associated recovery time as well as an associated amount of power savings. Recovery time is minimized by determining which of the video input signals is most likely to become active first, assigning a high priority to that signal and selecting a power saving mode based on characteristics of that signal. The likelihood of reactivation of a signal is determined by detecting the absence of normal vertical and/or horizontal synchronization signals.

Abstract: The present invention relates to an engine control device adapted to determine a basic fuel feed rate (Tp) in response to signals from a suction air flow rate sensor (20) and an air-fuel ratio sensor (20), and thereafter a fuel feed rate (Ti). According to the present invention, suction air flow rates (Q.sub.An-1, Q.sub.An-2) are calculated first on the basis of the last and the next to last fuel feed rates (Tin-1, Tin-2). The coefficients (A, B) required to correct the properties of the suction air flow rate sensor (20) are computed on the basis of these suction air flow rates. In the present invention, a fuel feed rate is determined finally on the basis of these coefficients.

Abstract: Method and apparatus for controlling the spark timing of an internal combustion engine is provided, wherein the output of a sensor for detecting the state of a means affecting the engine operation is detected prior to engine start, and the detected value is stored as an initial value. After engine start, the output of the sensor for detecting the state of the means affecting the engine operation is again detected, and this detected value is corrected by the stored initial value. On the basis of the corrected detected value, a command value of ignition point in time (command ignition timing) is calculated and used to control ignition timing.

Abstract: An up-counter counts pulses of a first pulse train of a variable frequency during each pulse-duration of pulses generated corresponding to the angular position of a crankshaft of an engine. The so counted value is transferred to a down-counter which counts pulses of a second pulse train with a constant frequency so as to diminish its transferred content. The down-counter produces an output signal as an ignition timing signal when its content decreases down to a predetermined value. In the ignition timing control device of such type, the first pulse train of the variable frequency can be provided by a novel advance angle establishing means in which a given short time period is divided into two time portions and from which two pulse trains of different frequency from each other are outputted for the respective time portions, the ratio of sharing being controlled in accordance with the number of revolutions of the engine and the opening value of the throttle.
