Title: Scanning device
Inventor: TAKEUCHI NORIYASU
IPC: G03B27/50
Filed: 1992-01-20
Abstract: PURPOSE:To eliminate the need of an electric cable having special specification by always giving rotating force in a direction where the cable is taken up to a take-up trunk, which is weaker than the force of rewinding the connection cable from the take-up trunk to the take-up trunk. CONSTITUTION:When an electric motor 12 is rotated in the normal direction, the part of the wire 4 between pulleys 7 and 8, and the part thereof between pulleys 8 and 9 are moved in a direction from the pulley 7 to the pulley 9, and an image read unit 2 is moved in a direction from the pulley 9 to the pulley 7. By this movement, the tensile force of the connection cable 13 is eliminated, but the take-up trunk 14 is driven to be rotated counterclockwise by the repulsive returning rotating force of a spiral spring by interlocking with such an effect. The cable is taken up to the trunk 14 by the length of the reciprocating distance of the unit 2, and the trunk 14 is moved in the left direction by the half of the reciprocating distance. At such a time, an electric part exists outside the reciprocating limit position of the unit 2, then the left end of the cable 13 is fixed.

Title: Manufacture of ultra-minute tunnel barrier
Inventor: SAKAMOTO TOSHIMORI
IPC: H01L29/76
Filed: 1994-01-27
Abstract: PURPOSE:To provide an ultra-minute tunnel element and a single electronic transistor, which are operated at 77 K. CONSTITUTION:A vertical step 19 of 50Angstrom  is formed by low-damage etching on a gallium arsenide substrate 20. A gallium arsenide layer 23, a monoatomic doped silicon layer 22 and a gallium arsenide layer 21 are epitaxially grown on the substrate 20 sequentially by an MBE method. Silicon is not doped into the side wall of the step. Thereafter, the grown layers are etched, and a thin line 25, which orthogonally crosses the step, is formed. The probability of a tunnel is determined by the height of the step. Since the height of the step is low in modulation doping, the interval between potential barriers can be largely provided. Then, the capacitance of the tunnel junction can be made small, and the element is operated at 77 K.

Title: Semiconductor photodetector
Inventor: MORITA TETSUO
IPC: H01L31/108
Filed: 1990-01-17
Abstract: PURPOSE:To reduce a dark current flowing to a semiconductor photodetector by bonding a reverse conductivity type semiconductor layer to a photodetecting layer to the opposite side surface of the photodetecting layer to a photodetecting surface. CONSTITUTION:A P-type semiconductor layer 12 is formed on a substrate 11 made of InP, etc., and an n-type GaInAs epitaxially grown layer is formed as a photodetecting layer 13 on the layer 12. Since the layer 13 is not Schottky- connected, an AlInAs epitaxially grown layer 15 is further formed thereon, and a pair of Schottky electrodes 16 are formed on the upper surface. Thus, since a structure in which the reverse conductivity type layer 12 to the layer 13 is bonded to the opposite side surface of the layer 13 to the photodetecting surface to which a light is emitted is formed, carrier existing in the layer 13 is depleted, and the resistance of the layer 13 is increased. Thus, a current scarcely flows to the layer 13, and a dark current is reduced.

Abstract: PROBLEM TO BE SOLVED: To stably manufacture a thin foil of a soft magnetic metal becoming a magnetic material of nearly <=10 μm to >=3 μm in thickness, performance of which is not lowered in a high frequency zone of 1000 MHz-1 GHz. SOLUTION: The foil of the soft magnetic metal which is worked into nearly <=20 μm to >=10 μm in thickness by rolling and annealing is formed into a desired thickness while vertically transferring it downward i.e., rolling it without applying a tension exceeding gravity. It is heated at the recrystallizing temperature or higher of the soft magnetic metal to recrystallize it. A thick foil e.g. a foil 1A of 100 μm on the market is taken out of a coil, and the thick one is allowed to roll by horizontally making it pass through a pair of rolling rolls 21a, 21b, 22a, 22b,... which are vertically positioned, however the foil 1B becoming nearly 10 μm in thickness is rolled by the rolling rolls 31a, 31b, 32a, 32b which are horizontally positioned avoiding the application of the tension exceeding gravity.

Title: Diazo copying material
Inventor: TAKAHASHI NORIHISA
IPC: G03C1/58
Filed: 1984-01-20
Abstract: PURPOSE:To obtain an image superior in light resistance and prevented from coloring on the background by using a specified hydrazone type coupler in combination with a metal salt capable of chelating with a coupling product. CONSTITUTION:A diazo copying material is composed of a diazonium salt, a pyridine deriv. as a hydrazone type coupler represented by the formula in which R is a cyclohexyl group optionally substd. by a lower alkyl group, and a metal salt capable of chelating with the coupling product. Since such a coupler itself is white, a sharp image free from coloring on the background can be obtained, and moreover, since it is soluble in water, a soln. for forming a photosensitive layer has a merit capable of being used as an aq. soln. It rapidly reacts with the diazo compd. to produce a sharply colored coupling product, i.e., a formazan dye. Since said dye is allowed to chelate with the metal salt, it is enhanced in stability and light resistance, and accordingly, a sharp high-density image free from coloring on the background can be obtained.

Abstract: PURPOSE:To prevent occurrence of waveform distortion and overload noise that occur at the time of overloading by making bit allocation to one having large predictive error electric power out of predictive coding processing sections large and transmitting at the time of overloading in which predictive error increases. CONSTITUTION:When an overload detecting circuit 15 detected that the level of predictive error from a subtracter 11 became large, that is, became the state of overload, the circuit outputs overload detection data, and makes allocation of quantizing bit of a predictive coding processing circuit having large predictive error electric power out of plural sequences large to prevent increase of quantizing error. Thus, as allocated number of bits to sequence having large predictive error electric power becomes large, bad influences of waveform distortion, overload noise, etc., can be prevented.
