Abstract: An access control unit provided in an LSI, that supports external devices with varying access times, comprises a clock, mask circuit, a wait signal generating circuit, a flip-flop and a wait cycle number setting register. The wait signal generating circuit calculates the number of wait cycles using a formula for determining a general term in an geometrical progression based upon the data currently set at the wait cycle setting register to generate and output a wait signal “wait.” The clock signal “clock” is input to another input terminal of the clock mask circuit. The flip-flop takes in data output by a low-speed external device or a high-speed external device in synchronization with the clock signal “clock” and provides the data thus taken in to a CPU with specific timing.

Abstract: The present invention provides a method of turning over a window that is laid over another window in order to peek a content of another window that is laid under the window in a pseudo-three dimensional manner, in a multi-windows computer system. The method includes the steps of (a) selecting a first window from the multi-windows by placing an object on the first window; (b) clicking the object on the first window to initiate an operation of turning over; and (c) dragging the object toward a direction to which the first window is to be turned over so as to unveil a second window that is laid under the first window, whereby enabling to peek a content of the second window.

Abstract: The present invention provides a device for signal control of a switch which outputs a first signal in response to a turning operation thereof and outputs a second signal in response to a depressing operation thereof. If one of the first and second signals is outputted in response to a corresponding one of the switch turning operation and the switch depressing operation and the other signal is thereafter outputted in response to the other operation within a predetermined period, the control device nullifies the other signal. With this arrangement, a heating cooker provided with the switch is prevented from performing an under-heat or over-heat cooking operation on the basis of a misoperation of the switch. Further, the need for resetting a cooking period is obviated which may otherwise arise from the misoperation of the switch.

Abstract: There is provided a semiconductor device in which substantially no deformation of a bonded wire occurs, and a method for producing the semiconductor device. A wiring pattern of a wiring substrate and an electrode of an IC chip are connected by a wire. A contact prevention resin whose height is higher than the highest position of the bonded wire, is adhered to the approximate center of the surface of the IC chip. If the wiring substrate warps due to heat from the lower metallic mold, an inner surface of an upper metallic mold placed on the wiring substrate abuts against the contact prevention resin, and decrease warpage of the wiring substrate. Accordingly, the wire is kept from contacting the inner surface of the upper metallic mold. Thereafter, the IC chips, the wires, and the like are sealed by injecting a mold resin into the molds.
