Abstract: A semiconductor integrated circuit has: a differential amplifier circuit including a first MOS transistor connected between a first node and a common node and a second MOS transistor connected between a second node and the common node; a first current supply circuit configured to supply current to the first node; and a second current supply circuit configured to supply current to the second node. A current supply ability of the first current supply circuit is variable.

Abstract: A data communication device includes a receiving circuit configured to receive a data signal in an active state. An intermittent activation control circuit activates the receiving circuit into the active state in a predetermined time interval. A control unit operates in response to the data signal received by the receiving circuit. Also, the control unit controls the time interval of the intermittent activation control circuit.

Abstract: An automatic plant diagnostic device and method are provided to inform disease conditions of the plant easily and early. An image memory of the device reads a color image of a plant and controls a display so as to display the image. An background color deleting unit deletes the background color from the color image on display, so that a leaf image can be obtained. A color change calculating unit detects values corresponding to hues of the leaf image and stores them in a memory on every date. After storing, the calculating unit further allows the display to display the values of hues on every date in form of a graph.

Abstract: The invention discloses a front fender reinforcing structure for automobiles. A fitting part for a clip member is formed between a body work outside panel and a plate disposed outside of the outside panel, one end of the clip member for engaging a front fender with the outside panel is fitted into the fitting part, and an opposite end of the clip member is placed and disposed at a window frame section at the rear upper part of the front fender so that the window frame section of the front fender is engaged with and held by the outside panel. Thus, the clip member is positioned between the easily deformable window frame section of the front fender and the outside panel to support the back of the easily flexible window frame section of the front fender. Consequently, the window frame section of the front fender can be prevented securely and effectively from being deformed.

Abstract: A relay module, by which a time required when a motor is optionally mounted on a machine tool or removed therefrom can be omitted. The relay module comprises only a case and terminal screws of an electromagnetic contactor for a motor from which internal components are removed. The relay module is disposed when the motor is not connected and an electromagnetic switch is disposed when the motor is connected. Further, the relay module or electromagnetic switch is wired at all times. When the motor is optionally mounted on the machine tool, it suffices only to replace the relay module thereof with the electromagnetic switch and no wiring job is additionally required. Further, when the motor is removed, it suffices only to replace the electromagnetic switch with the relay module and a job for removing the wiring is not necessary.
