Inventor: KAMADA HIROSHI
IPC: G05D1/02

Abstract: In a steerable vehicle including automatic steering means signal processing circuitry is provided for employing image data provided by a camera (1) mounted on the vehicle to produce control signals for use in operating the automatic steering means of the vehicle to cause the vehicle to follow a guide line on a surface over which the surface is travelling. 
     The circuitry comprises guide line recognition means (21, 22, 23) for determining which of the image points represented by such image data are line-indicating points characterised by image data values satisfying predetermined conditions consistent with passage of the guide line through points on the surface that correspond respectively to the image points. The circuitry also includes density determining means (31 to 35) for employing data from the guide line recognition means (21, 22, 23) to determine locations where the density of such line-indicating points is maximal across the field of view of the camera, thereby to determine the course of the centre of the guide line over the surface. This information can then be employed in, for example, a fuzzy inference method to produce the required control signals for use in operating the automatic steering means of the vehicle. 
     Such circuitry can enable the guide line to be detected more precisely and quickly, and can improve the reliability of the vehicle steering control.

Abstract: A contact shutter mechanism in an IC socket has a socket body which has a plurality of contacts arranged in such a manner as to be able to contact with terminals of an IC package, and a contact shutter member vertically movably dis­posed on the socket body and adapted to displace, when being pushed down, the contacts backward against resiliency thereof to cancel the contacted state between the terminals of the IC package and the contacts and to bring an IC loading portion into a released state. The shutter member has a contact pushing portion adapted to rendering a backward displacement force to the contacts. The contact pushing portion is formed in an inclined surface. The inclined surface is formed at a front-stage pushing portion in a gentle inclined surface and at a rear-stage pushing portion in a steep in­clined surface.

Abstract: The subject of the invention is a method for manufacture of sandwich-type moulded articles and panels, mainly of textile fibre structures, which contain fibres having different thermal properties, by pressure, heat and moist hot air, using moulds, which have a greatest-possible, uniform porosity, to press panels and moulded articles with a sandwich structure and cool them in the same cycle, the moist hot air and a special design of the mould causing a positive pressure to be achieved in the mould and consequently in the fibre structure, which pressure makes the outer sides in particular of the fibre mats set largely evenly on the mould surfaces, the inner structure of the moulded articles or panels then having a lower density. By using this method, the weights of moulded articles and panels to be described can be reduced, which is of decisive significance in terms of price and acceptance on the market for energy reasons alone. Furthermore, by using fibre systems comprising the same polymer, reuse is largely possible, since then it is possible to dispense with binder systems of a different type.

Abstract: A loading lever (101) having loading lever pins (111a and 111b) is fixed on a main chassis (51). Loading arms (3a and 3b) having loading arm depressed portions (109a and 109b) are rotatably attached to a slide chassis (1). The loading arm depressed portion (109a) engages with the loading lever pin (111a), and loading arm depressed portion (109b) is engaged with the loading lever pin (111b), and in this state, the slide chassis (1) moves in the direction of the arrow B. Therefore, loading arms (3a and 3b) moves in the direction of the arrows J and K. Since the loading arms are rotated, it becomes unnecessary to slide the loading lever, and therefore, the structure of the magnetic recording reproducing apparatus can be made simple.

Abstract: The screen packs as well as the breaker plates of a melt filter supporting the screen packs are each mounted in holders 16 which are guided in recesses of a swing mounting or a disc 5 between a cover plate 1 and a base plate 3. The holders 16 have a spherical cap 23 on one side for the attachment of a nozzle of an injection moulding unit, and they are supported at the rear side against an annular supporting surface which surrounds the melt entry into the mould. The holder that is respectively in a working position is thus pressed against its support only during the shot of the injection-moulding unit, so that the contact pressure of the nozzle can ensure a complete sealing and the disc itself, as well as the holders not in their working position, are not loaded. After the completion of the shot, including the necessary holding pressure, the nozzle of the injection-moulding unit is withdrawn so that the disc with all holders is then freely moveable and that the following holder can be transported into the working position 21 without substantial stressing and with preservation of the sealing surfaces to a high degree. <IMAGE>

Abstract: A magnetic reproduction apparatus which uses a magnetic recording medium on which frequency-modulated signals produced by frequency-modulating a carrier with video signals are recorded, and demodulates reproduced signals from the magnetic recording medium into the video signals. The apparatus includes a frequency converter for causing the reproduced signals to shift to a higher frequency region and a pulse-count-type FM demodulator for demodulating the reproduced signals which have shifted to the higher frequency region into the video signals. This arrangement restrains the mixing of the reproduced signals in the video signals. Therefore the video signals are reproduced with lessened waveform distortion, achieving a high-quality image.

Abstract: The disclosed novel doping method makes it possible to tailor the effective activation energy of a dopant species in semiconductor material. The method involves formation of very thin layers of δ-doped second semiconductor material in first semiconductor material, with the second material chosen to have a bandgap energy that differs from that of the first material. Exemplarily, in a Be-doped GaAs/AlGaAs structure according to the invention the effective activation energy of the dopant was measured to be about 4 meV, and in conventionally Be-doped GaAs it was measured to be about 19 meV. The invention can be advantageously used to dope III-V and II-VI semiconductors. In some cases it may make possible effective doping of a semiconductor for which prior art techniques are not satisfactory.

Abstract: Disclosed is a method and system for allowing resource control in a UNIX-based system to be done on an aggregate, or group, basis. This enables both access control and accounting to be done in units of groups instead of units of users. This design is upwardly compatible with the current implementation which does resource allocation and accounting in units of users. In addition, the method and system provides greater flexibility in selecting the system availability policy to be enforced. A resource quota scheme is introduced wherein a pooled resource account allows a system administrator to segregate processes into critical/non-critical classifications.

Abstract: Previously known methods of securing video recorders and/or for magnetic-tape cassettes used with these video recorders against unauthorised use, such as for example numerical locks, have the disadvantage that in this way the video recorders are completely blocked. In the case of the present invention, this disadvantage is avoided by a security code being both stored in the video recorder and recorded onto each magnetic-tape cassette used in the video recorder. Each time a magnetic-tape cassette is used, the security codes are compared and use is permitted only if the security codes coincide.
