Abstract: An optical disk master (19) having a diffraction structure including guide grooves (8) and small pre- pits (9) of a width narrower than a diffraction limit determined by a wavelength of light used is produced by preparing a photoresist layer (21) subjected to anti-dissolution surface treatment, narrowing the spot diameter of a zero-th diffracted beam irradiated on the photoresist layer by means of a super resolution optics (22), and effecting high contrast development to leave behind, as it is, a portion of the photoresist layer exposed to adverse higher order diffracted beams caused by super resolution. An optical disk (45) produced from the master has a diffraction structure including tracks and/or pre-pits formed along a spiral track or concentric tracks (7) and having a width narrower than a diffraction limit determined by a wavelength of light used in the course of formation of the diffraction structure.

Abstract: Arsenic ions are implanted into an element region of a silicon substrate (31) so as to form a first impurity region (35). Then, an insulating film (36) is formed on the silicon substrate in the element region, followed by forming a heat resistant film (41) on the entire surface of the silicon substrate. Further, a resist film (37) is formed on the silicon substrate, followed by patterning the resist film to form an opening on at least the first impurity region. After the patterning step, the heat resistant film positioned below the opening of the resist film is removed, followed by implanting phosphorus ions into the substrate using the patterned resist film as a mask so as to form a second impurity region (38). In the next step, the resist film is removed and, then, annealing is applied with the heat resistant film used as a mask. After the annealing step, the resist film is removed, and an annealing is performed with the heat resistant film used as a mask, followed by removing the insulating film using the heat resistant film as a mask. Finally, a tunnel oxide film (39) is formed on that portion of the silicon substrate, followed by forming an electrode (40) on the tunnel oxide film so as to manufacture a desired nonvolatile semiconductor memory device.

Abstract: A detachable IC card (2a) applicable to a portable data processing device referred to as an "electronic organizer" is disclosed. The IC card is formed of microstrip lines formed on a dielectric substrate (281). An antenna (201a) receives an unmodulated carrier signal (20a) externally applied and guides the received signal to microstrip lines (212a₁, 212a₂) for impedance conversion. Cathode potential of a diode is varied in response to a data signal outputted from a CPU (222a), so that the barrier capacitance of the diode varies. Accordingly, the carrier is reflected according to the data signal and radiated toward the electronic organizer main body through the antenna. An oscillator for data transmission is not required in the IC card, so that an internal buttery having a large capacitance is not required, either. As a result, without increasing the size and weight of the device, data transmission by radio from the IC card can be accomplished.

Abstract: An improved tapered notch antenna configuration is provided. H-plane pattern directivity is achieved by splitting the planar tapered notch into two diverging surfaces to increase aperture dimension in that plane. 
     A first embodiment describes a stripline feed approach where the ground plane conductors and attendant dielectric substrates diverge in the notch taper region. 
     A second embodiment utilizes a conductor plane (411) containing a notch (403,409) and coplanar transmission line (407) which is imbedded at half-depth within an essentially thin dielectric slab. The conductor plane and the dielectric slab separate into two equal but diverging conductive surfaces (413,415) on separate dielectric substrates in the taper region. 
     The improved tapered notch antenna, according to the invention, provides increased H-plane directivity, while retaining the prior art-features of feed compactness, low-cost, and repeatability.

Whenever the available cache space is less than the write domain needs, then the data transfer is subsetted to match the available cache space. Calculations for determining the maximum cache space is described and sets of machine operations are disclosed for effecting the above operations.
