Title: Waveform-shaping circuit
Inventor: INOUE AKIO
IPC: H03K12/00
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To automatically maintain a duty ratio at 50% and to reduce the influence from noises. SOLUTION: The maximum output value of a reception circuit IC1, with which a sine wave voltage is defined as a negative input, and the voltage value of a prescribed negative voltage power source VR are divided by a voltage- dividing circuit and this voltage divided output is fed back to the positive input of the IC1, so that a comaprator circuit can be constituted. The voltage-dividing circuit is composed of a resistor R2 connected between the output of the circuit IC1 and a voltage-dividing point and a resistor R3 connected between the voltage dividing point and the prescribed negative voltage power source VR, so that the resistance value of the resistor R3 corresponding to the resistance value of the resistor R2 can become double the voltage value of the prescribed negative voltage power source, corresponding to the maximum output value of the circuit IC1.  Since the sine wave voltage is compared with the positive and negative threshold values of the equal absolute value and a binary waveform is outputted, even if some noise voltage is superimposed on the input sine wave, no chattering occurs in the sine wave output so that troubles do not occur, even when this circuit is used for a digital processing circuit.

Title: Image forming device
Inventor: MAEDA HIROSHI
IPC: G03G15/00
Filed: 1992-06-22
Abstract: PURPOSE:To express area blocks of a color original such as a map to be easily observed by printing an image in a mono-tone based on image data converted from original image data so that a density histogram obtained from the original image data forms plural separated and flat areas. CONSTITUTION:When the map mode is selected, a CCD section 51a of an image data input section 51 reads an image and a histogram(Hg) processing section 51b generates a density Hg. Furthermore, image data are stored in a memory 61 via an error spread processing section 51c. Then the image data are subject to multi-value processing by a multi-value processing section 2, subject to density conversion by a density conversion section 52d, an image process section 52f detects a peak and a notch of the Hg at the input to make separation and flat processing. The image data are subject to 4-value processing again by an error spread processing section 52g and a compression processing section 52g, compressed by the compression processing section 52h, the result is stored in the memory 61 and the data are read by an image data output section 53 and printed out. Thus, the area block of a color original is printed out to be easily observed.

Title: Production for radio wave reflecting antenna
Inventor: NAKAJIMA AKIOMI
IPC: H01Q15/14
Filed: 1983-09-07
Abstract: PURPOSE:To eliminate a fear of peeling between individual layers and to prevent rust of metals by melt-spraying a metal to a glass fiber layer, which is formed into a prescribed shape, to form a metallic layer and impregnating this metallic layer with a synthetic resin and hardening the synthetic resin. CONSTITUTION:A glass fiber cloth is put in a shaping mold and is formed into a prescribed shape along the surface of the mold to form a glass fiber layer. Thereafter, an adhesive such as a polyester, an acrylic resin, or the like is applied by spraying or the like and is hardened by heating for about 30min at 50- 200 deg.C and is fixed. In the next process, 20-200gr/m<2> metal such as Al, Zn, or the like is sprayed theremally to the surface of the glass fiber layer to form a metallic layer. The melt-sprayed metallic layer not only forms a reflecting layer but also is stuck to intersections of glass fibers to fix glass fibers. In the molding process, the glass fiber cloth which is provided with the metallic layer and is shaped is put in a forming mold and is formed by injection of a thermosetting synthetic resin liquid. Since the synthetic resin passes through the metallic layer from the glass fiber layer to cover the surface in case of this forming, the whole of them are made into one body.

Filed: 1986-07-11
Abstract: PURPOSE:To obtain an extremely small-sized, high-resolution rotation detecting device by providing a magnetic sensor opposite a magnetic recording part which is subjected to multipole magnetization at the periphery of a rotating shaft provided rotatably by bearings. CONSTITUTION:The magnetic recording part 6 which is subjected to multipole magnetization so that their polarities are alternately inverted in the rotating direction of the rotating shaft 1 provided rotatably to a holder 2 by the bearings 3 and 4 and fixed to a fixed shaft 5 is arranged on the peripheral surface of the rotating shaft 1 between the bearings 3 and 4. On the other hand a magnetic sensor 7 is fixed to a magnetic sensor fitting part 8 opposite the magnetic recording part 6 and this sensor 7 is used to transduce the periodic variation of a magnetic field produced by the rotation of the rotating shaft 1 into an electric signal. With this assembly, vibrations of the magnetic recording part 6 to the magnetic sensor 7 due to the rotation of the rotating shaft 1 are extremely small, so the gap length between the magnetic sensor 7 and magnetic recording part 6 and the recording wavelength of the recording part 6 are reducible, so that high resolution is obtained.

Abstract: PURPOSE:To make possible continuous wavelength control by performing the current injection uniformly into a phase adjusing region and a DBR region, and making the coefficient GAMMApc of confinement of light in the tuning layer of a phase adjusting region larger than the coefficient GAMMAdbr in the DBR region. CONSTITUTION:A diffraction grating 10 is provided partially on an n-InP substrate 1, and thereon parallel insulating films 20 are formed to sandwich a stripe region, and by MOVPE method, an n-InGaAsP guide layer 2, a MQW tuning layer-cum-active layer 7, and a P-InP clad layer 5 are grown. Thereupon, since the width of the insulating film 20 varies with each region, the MQW tuning layer and active layer 7 in the stripe region sandwiched by the insulating films 20 from a DBR region to an active region is thick, and the composition of wavelength changes stepwise to long wavelength. Accordingly, continuous wavelength control can be made by patterning both sides of the insulating films 20 again in stripe shape, and selectively growing a P-InP clad layer 5' and a P<+>-InGaAs cap layer 6 by MOVEP so as to form an electrode.
