摘要： An improved output circuit that provides an output signal having a predetermined high voltage level regardless of the voltage of a high-potential power supply is described. In one embodiment, the invention includes a first transistor and a second transistor connected in series between a high-potential power supply and a low-potential power supply, and a third transistor connected in parallel to the first transistor between the high-potential power supply and the node between the first and second transistors. The first and second transistors are n-type MOS transistors and the third transistor is a p-type MOS transistor. In another embodiment, the invention further includes a supply voltage detector for detecting a voltage of the high-potential power supply and supplying a voltage signal to the first and third transistors for selectively enabling one of the first and third transistors based on the voltage detected.

摘要： A small computer system interface (SCSI) controller for continuously or intermittently performing communication of plural sets of data. The SCSI controller includes a data register for temporarily storing a set of data, a SCSI interface for transmitting the data stored in the data register in units of 2 bytes and for receiving data from another SCSI controller in units of 2 bytes, a byte counter for counting the number of bytes of data that is transmitted from or received by the SCSI interface, an internal processor for controlling initial setting of a target count value of the byte counter, and a transfer control circuit for controlling transmission of the data stored in the data register from the SCSI interface and reception of data by the data register via the SCSI interface. In data communication in units of 2 bytes, the SCSI controller can prevent transfer of dummy data that is ineffective, to thereby provide efficient data communication.

摘要： A camera comprises: a photographing lens; a viewfinder lens lying behind the photographing lens so that an object to be photographed can be viewed; a first reflector mirror capable of being displaced between a first position, at which the first reflector mirror intervenes between the photographing lens and viewfinder lens so that light emanating from the photographing lens is reflected horizontally substantially at 90.degree., and a second position at which the first reflector mirror has retracted from between the photographing lens and viewfinder lens; a second reflector mirror lying by the side of the first reflector mirror so that the light emanated from the photographing lens and reflected from the first reflector mirror is reflected vertically substantially at 90.degree.; an image forming plane lying below the second reflector mirror so that the light emanated from the photographing lens and reflected from the second reflector mirror forms an image thereon; and an aperture for determining a picture size that defines a zone to be exposed of film lying on the image forming plane.
