Filed: 1977-09-27
Abstract: PURPOSE:To realize a 90 deg.-twist waveguide element by providing a thin coupling element to the connection surface of waveguides twisted by 90 deg. and connected discontinuously so as to couple waveguides each other. CONSTITUTION:A radio wave can be transmitted by giving band-pass characteristics and prescribed coupling degree by using a thin metal plate for the connection surface between waveguides 3a and 3b. Namely a high-frequency magnetic field infiltrates into one waveguide, but intersects, so that no coupling will occur. Then, thin metal plate 6 of strip line 5 is provided between waveguides 3a and 3b so that the magnetic field of waveguide 3a will couple in the part parallel to the X-X' axis and its induced current will flow even to the part parallel to the Y-Y' axis. Consequently, the high frequency magnetic field of waveguide 3b will be excited.

Abstract: PURPOSE:To control a liquid crystal layer heating heater in such a manner that the temperature of the liquid crystal layer does not become lower than the operating temperature range by measuring the temperature of the liquid crystal layer through detection of the change in the impedence of refractive index by the temperature of the liquid crystal layer itself. CONSTITUTION:The temperature at which the impedance of the liquid crystal layer changes abruptly changes with the frequencies applied, therefore, if suitable frequencies are selected, the on-off controlling of a heater is accomplished without assembling a bridge circuit. The change in the refractive index on the liquid crystal layer is detected by opposedly disposing a light source 8 and a photodiode D2 by way of a liquid crystal element 1 in-between, whereby the on-off controlling of a heater 6 is performed. It is also possible to use a GTO element in order to make circuit constitution simple, or to provide the one for detection separately from the electrode for displaying and an electric power source in order to facilitate temperature setting or to provide plural detecting parts in order to be adapted in the case when there is a difference in the temperature distribution of liquid crystal elements.

Abstract: PURPOSE:To improve the contact with a thermal recording paper and the thermal efficiency of a thin-film type thermal head by a method in which the surface of a heating section is made higher than the surrounding of the sending direction of a paper or formed at the same plane as the surrounding. CONSTITUTION:The surface of the portion between electrode films 3a and 3b in a heat insulator glazed layer 2 is made higher than or matched with the surfaces of the films 3a and 3b. A glaze layer 2 as a heat insulator layer is formed on an alumina base plate 1, and a resist pattern film 21 insoluble in an etchant gas is formed on the layer 2. The surface of the layer 2 is dry-etched by an etchant gas to form a groove in an unnecessary portion of the layer 2. An electrode film 3 is formed by vacuum vapor deposition on the resist pattern film 21 and the groove of the layer 2. The film 21 is dissolved by an organic solvent by a lift-off method and the film 3 on the film 21 is also removed out. The portion where no groove is formed of the glaze layer 2 can thus be exposed.

Abstract: PROBLEM TO BE SOLVED: To prevent malfunction owing to a reception of non-target signals by discriminating the type of a portable telephone set from a reception signal and giving information on an incoming call only when the set belongs to a portable telephone set in question. SOLUTION: A specified frequency band of a received signal is extracted by a filter 2A of an incoming call informing device mounted separately from a radio telephone set, and a low frequency component detected in a detection circuit is amplified and shaped. Then, it is inputted to a frequency/voltage F.V conversion circuit 7 consisting of a pump circuit, an arithmetic circuit and the like to obtain voltage corresponding to the frequency component. The voltage is then applied to the other input terminal of a discrimination circuit 8 including an operational amplifier to an input terminal of which a reference voltage is applied. The type of the related portable telephone set at present is discriminated from a relation with voltage corresponding to the digital frequency.  A driving circuit 5 drives a vibration motor M based on output voltage from the discrimination circuit 8 or makes a light-emitting diode emit light and gives information of the incoming call. In an analog type radio telephone, both frequency and output voltage and '0', thus it is discriminated at once.

Title: Digit matching circuit for floating point

IPC: G06F7/00
Filed: 1990-05-07
Abstract: PURPOSE:To improve the operating speed of the circuit by starting a shift action according to the difference of an exponent part outputted from a subtractor regardless of the presence or absence of a stingy expression and adding one later to a mantissa part if the stingy expression is confirmed. CONSTITUTION:The decoders 25 and 27 are connected to the stingy expression detecting circuits 23 and 24 which detect the presence or absence of the stingy expressions according to a fact whether an exponent part is set at zero or not and also connected to the subtractors 15 and 17 respectively for generation of the addends. The outputs of both decoders 25 and 27 are added to the shift results by the bit OR 29 and 31 and sent to the selectors 33 and 35. The selectors 33 and 35 output the shifted bit trains as the mantissa parts and also output the unshifted original mantissas as they are according to the difference between both mantissa parts AE and BE. A selector 37 inputs two exponents and outputs the larger one of both exponents. Thus a shift action is started regardless of the stingy or non-stingy expression of the mantissa part. Then the operating speed is improved for a digit matching circuit for floating points.

Abstract: PROBLEM TO BE SOLVED: To prevent deformation such as wavy parts on the surface of a substrate by forming a master disk made of Ni so as to have a shape corresponding to the surface shape of the substrate formed in one direction surface and have its thickness more than a specified dimension. SOLUTION: A recessed and projecting pattern formed in one direction surface of a master disk 1 is formed according to the shape of a substrate to be formed, and its thickness is set to a dimension t1 of >= about 0.4 mm. The strength of this master disk 1 itself is increased if t1 is >= 0.4 mm, but about 0.4 mm is desirable from the viewpoint of a manufacturing process. If the thickness of the master disk 1 is set >=0.5 mm, uneven thickness occurs in a surface during manufacturing and, as the thickness is larger, unevenness is increased and thus it is more difficult to suppress such unevenness. The master disk 1 is formed so as to have a mirror-like surface if a substrate to be formed is a mirror type.
