摘要： This invention relates to a method and an apparatus for automatically generating a control program for a computer controlled system, such as a plant. A plurality of general-purpose standard program modules (49, 51) are prepared in advance, and a choice is made between these standard modules, a standard module chosen being indicated in the form of pictorial information on a display (21). Non-standard program modules (50, 52) are produced by combining standard modules arbitrarily on the basis of an operation plan, and stored in the form of pictorial information in a stacker (155). The non-standard modules are also grouped according to arbitrary program functions and produced in multiplicity. A source program is produced by compiling these non-standard modules, and the non-standard modules are then assembled to produce non-addressed intermediate-stage modules. Load modules can be made by linking and editing these intermediate-stage modules.

摘要： A multi-projection image display device using a plurality of image projectors to form one picture on a screen, in which images projected from the projectors are smoothly connected with one another, so that seams of the images do not appear conspicuously. The image display device has projectors (0121, 0122, 0123, 0124) and a screen (0140) laid out in such a manner that maximum image projection ranges (0151, 0152, 0153, 0154) of the respective projectors ovelap the adjacent ranges. An image signal control unit (0110) for processing an image signal supplied from an external image input (0180) has, therein, a member for cutting out a partial image area dealt with by each projector, an image converting member for performing geometric transformation and local color correction of the partial image, and an arithmetic control member for controlling the image converting member on the basis of image information inputted from a screen state monitor camera (0130). With this structure, smoothing of the seams between the images may be realized simply by image signal processing, and precise adjustment of the optical system of the projectors becomes unnecessary.

摘要： The ratio BrOR of the residual magnetic flux density in a circumferential direction to the residual magnetic flux density in a radial direction is 0.95 - 1.05 and the ratio HcOR of the coercive force in a circumferential direction to the coercive force in a radial direction is 1.05 - 1.2 in the substrate surface of a magnetic recording medium. Therefore, a high output resolution, a low medium noise and a high track recording density are simultaneously achieved in recording at a high line recording density. When a magnetic storage apparatus is constituted by using a high S/N magnetic recording medium like this, a magnetic disc apparatus which has a high surface recording density, is low in cost and small in size, and a large capacity and a high reliability can be provided.

摘要： A high-frequency power amplifier circuit device, with the frequency of the operating band between 500 MHz and approximately 10 GHz and power level of not lower than 0.5 W, has a problem to be settled that no increase in power level can be expected in proportion to the increase in the gate width of a power transistor. In addition to the solution of the above problem, an optimal high-frequency power amplifier circuit device and a high-frequency transmission system using the device are constituted to reduce the space in the matching circuit, to improve the linearity and to prevent oscillation in a power transistor (10) and an input/output matching circuit in such a way that the grounds (2) and (4) of an input-side strip line (61) and output-side strip line (62) are separated from each other and the grounds (2) and (4) are respectively connected to an input-side ground electrode (24a) and output-side ground electrode (23a) provided on a semiconductor chip carrying the power transistor (10). Consequently, the effective source impedance component which has been the cause of the deterioration of high-frequency power amplifier circuit in mutual conductance can be reduced.

摘要： Optical signal communication equipment and optical communication system which can be suitably used even when the transmitting speed and capacity of information transmitted by using optical signals are increased. On the optical signal transmitting side, signal light is generated by causing induced emission in an active medium by supplying exciting light to the medium in accordance with transmitting signals. The exciting light is supplied to the active medium in such a way that naturally emitted light is made incident to a semiconductor layer and the component of the light having a specific wavelength is Bragg-reflected by modulating the refractive index of the semiconductor layer by impressing the voltage pulse correspdoning to the transmitting information upon the semiconductor layer, and then, the reflected light is supplied to the medium as the exciting light. Since the Bragg reflection and associated induced emission show excellent responsiveness to voltage signals having pulses widths of 1x10 second on shorter, an optical communication system which can transmit optical signals at a transmitting speed of up to 100 Gb/s can be realized.

摘要： A controller of an electric car for controlling a motor which drives a wheel of the electric car by a vector control inverter for controlling the primary current of the motor which is divided into an exciting current component and a torque current component which are respectively controlled by the command values of the components, characterized in that the controller comprises a means which detects the wheel speed (including the rotor frequency of the motor which is proportional to the wheel speed), a means which detects slip and skid of the wheel in accordance with the differential coefficient (change rate with time) of the detected wheel speed, a means which detects the readhesion of the wheel in accordance with the differential coefficient and 2nd order differential coefficient of the detected wheel speed and a means which adjusts the torque current component command value in accordance with the detection results of both the detecting means. The readhesion point of the wheel can be found when the wheel slips or skids, and the torque current component of the motor can be restored in a short time accordingly by utilizing the high speed response of the vector control. Therefore, even in a state such as a rainy weather in which the adhesion factor is small, the torque can be efficiently utilized to a physical adhesion limit, so that the acceleration/deceleration of the electric car can be increased as high as possible.
