摘要： A visible telephone includes a housing in which a video camera is accommodated in a manner that an aperture thereof is directed to the front. The camera is fixed to a rotatable holder which is rotated by an operation of a knob outside the housing, responsively, an angle of declination or elevation of the aperture of the camera is changed. The camera includes a lens system and a solid-state image sensor which converts a light image from the lens system into an electrical signal (video signal), which is mounted on a circuit board. The solid-state image sensor is responsive to at least an infrared light. On the same or the other circuit board, an infrared LED is mounted. The infrared LED is lightened at necessary timing to expose a person or subject in the front of the aperture of the camera.

摘要： A communication device such as a video telephone is connected to a telephone line together with a telephone set at both parties. In response to an operation for removing a handset from a hook of the telephone set at this party, the video telephone at this party is initiated. Each of the video telephones includes a mode selecting switch and DTMF receiver which receives a DTMF signal from one of the telephone sets and decodes a received DTMF signal to output data representative of the mode of the video telephone. When a flag "1" is set, a mode of the video telephone at this party can be controlled in response to the DTMF signal which is received by the DTMF receiver from the telephone set at this party and, when a flat "2" is set a mode of the video telephone at this party can be controlled in response to the DTMF signal which is received by the DTMF receiver from the telephone set at the other party.

摘要： A memory array divided into a plurality of sub-memory-arrays is disposed on a chip so that, if a specified sub-memory-array is selected by a sub-memory-array selecting circuit, a normal read/write operation is performed with respect to the sub-memory-array based on an address indicated by a group of external address signals. At the same time, a clock generator for self-refresh mounted on a chip generates a word-line basic clock for self-refresh and a word-line basic clock for refresh, thereby selecting the word lines in the sub-memory-arrays which have not been selected. Prior to a predetermined time at which the sub-memory-array subjected to a refresh operation is subsequently selected, a refresh halt signal is outputted so as to forcibly halt the refresh operation, thereby preventing insufficient recharging of a memory cell. Each of the plurality of sub-memory-arrays stores, of sequential sets of image data, data on one frame or one field.

摘要： A machine tool comprises an upstanding column, a tool-driving unit vertically movable on the column, and a pair of guide rails on a front surface of the column to extend vertically thereon and horizontally spaced apart from each other for guiding the upward and downward movement of the tool-driving unit. The tool-driving unit includes a lift frame on the guide rails and a tilting-type turret head which is supported on a front surface of the lift frame and is rotatable about an axis inclined relative to the longitudinal direction of the frame in a horizontal plane. One of the pair of guide rails is relatively disposed forwardly of the other guide rail, so that the individual guide rails both assume positions close to the turret head thereby to minimize the amount of overhang of the tool-driving unit.

摘要： The invention provides a method for manufacturing a semiconductor device, wherein a semiconductor substrate is vertically etched to form a groove, antioxidant insulating films are formed on the side walls of the groove, and local oxidation is performed. Lateral extrusion of an oxide film which is a so-called bird's beak and a projection of the oxide film which is a so-called bird's head are substantially eliminated. As a result, the active region of the transistor, that is, the element formation region may not be narrowed, providing high packing density and high precision. Furthermore, the surface of the semiconductor substrate is flattened to prevent short-circuiting and disconnections of wiring layers. Stable manufacturing process provides a high yield of the semiconductor device. Electrical characteristics of the semiconductor device are greatly improved.
