Abstract: A driving device for a motor has a mounting substrate mounted to a base substrate. Highly heat-generating components such as a switching element for PWM control are mounted to the mounting substrate and only less heat-generating circuit components are mounted to the base substrate. The mounting substrate has a base plate part made of a metallic plate material surround by a molded insulating material but includes a heat dissipating part where the insulating material is removed and the internal metallic plate material is exposed.

Abstract: A switch device for rotating and stopping a DC motor includes a first switch element having two moving contacts, two normally open NO contacts and two normally closed NC contacts, a second switch element having one or two normally closed NC contacts, and an operating element. The operating element serves to connect the two moving contacts individually to input terminals of the DC motor, the two NO contacts to a voltage source line at a higher voltage, and each of the two NC contacts of the first switch element to another voltage source line at a lower voltage such as the ground potential, each through the NC contact, or one of the two NC contacts, of the second switch element. The NC contact of the second switch element is maintained in an open condition during a period from when either one of the NO contacts begins to change from a closed condition to an open condition until the corresponding NC contact of the first switch element finishes changing from an open condition to a closed condition.

Abstract: A switch apparatus of the invention can avoid contact damage without inviting a drastic increase in a size even when applied to a high power source voltage and does not deteriorate return feeling to a neutral state. The switch apparatus includes a switch A for cutting off connection between one side driving input of a DC motor and a negative plate side power source, a switch B for cutting off connection between the other side driving input and the negative plate side power source, and a switch C for cutting off connection between the one side driving input and the positive plate side power source and connection between the other side driving input and the positive plate side power source, wherein the switch A and the switch B are normally-closed type switches and the switch C is a normally-open type switch. The switch C is opened at a predetermined time before the switch A or the switch B is closed, and cuts off in advance a power source route to avoid the occurrence of dead short-circuit.

Abstract: A switch unit is provided which is free from causing contact damage even in case applied to a high power voltage, whose switch unit is not greatly increased in size. Switches A and B are to take a motor stop status, a motor forward rotation status and a motor reverse rotation status. A switch C is to electrically connecting and disconnecting between the switches A and B and the power source. This switch C, when the switches A and B transits from the motor forward rotation status or motor reverse rotation status into the motor stop status, is operated from a connection state to a disconnection state at a time of any of completing the transition to the motor stop status and prior to a predetermined marginal period of time.

Abstract: A power-window control device is provided which is capable of inexpensively avoiding the occurrence of a failure, not to overlook in safety, due to a short-circuit (including current leak) at between adjacent ones of switch terminals. The switch terminals are arranged in a combination that the terminals having a possibility to cause a failure due to short-circuit are not in an adjacent relationship. Specifically, in the case of a configuration of FIG. 1, arrangement is made such that there is no adjacent relationship between the MU and the COMA, the MD and the COMA, the NC and the COMA, the NC and the NO, the NC and the COMS, the NO and the COMA, the NO and the COMS, and the COMA and the COMS, e.g. in an order of the COMS, MD, NO, AD, COMA, AU, NC and MU.

Abstract: In an image data display control device wherein image data that are stored in a video RAM are to be sequentially read and converted into video signals for a display, writing and reading of the image data in the video RAM is so controlled that the capacity of the video RAM can be reduced. The image data display control device that performs such an operation includes a video RAM having an area for storing image data; a converter, which converts image data read from the video RAM into video signals; and a controller, which writes image data to the video RAM and reads the image data from the video RAM. The controller switches between the two areas that are obtained by dividing the area of the video RAM for storing the image data in order to alternately perform data writing and data reading.

Abstract: In a switch, the speed at which contacts are separated from each other is increased without depending on the speed at which an operating member is operated, so that an arc is prevented from being generated, to prevent the operating member to be deformed by heat generation and prevent the durability of the switch to be decreased due to the abrasion of the contacts. A movable contact member having movable contacts at both its ends is swingably supported with a common fixed contact projecting upward and serving as a fulcrum. A leaf spring is fixed to a slider. The leaf spring has a portion projecting in a U shape. The U-shaped portion is engaged with the center of the movable contact member. When the slider is moved, the U-shaped portion is distorted in the transverse direction. When the slider is further moved, the U-shaped portion gets beyond the fulcrum, so that the movable contact is rapidly separated from a normally open fixed contact.
