摘要:
An improved serial-parallel type A/D converter is disclosed herein. A gate circuit 7 applies signals S11' to S14' provided from an encoder 3 only in a fine comparison period to switching circuits 11 to 14 as switching control signals S11 to S14. In the fine comparison period, one switching circuit is turned on, so that a fine comparison voltage is applied to voltage comparators 21 to 23. Since all of the switching circuits are turned off in a coarse comparison period, correct coarse comparison voltage is provided from a reference voltage generating circuit. As a result, a correct conversion in the coarse comparison period can be performed.

An improved parallel-type A/D converter is disclosed, which includes encoder 3 constituted by a pseudo-NMOS type ROM, and encoder 28 constituted by a pseudo-PMOS type ROM. These encoders are connected to the outputs of pre-encoder 2. Averaging circuit 29 receives binary data provided from two encoders to provide average value data of these as converted binary output data. Even in case of multi-addressing, an averaging circuit can provide correct data as converted data. As a result, an A/D converter which is not affected by noise or the like has been obtained.
摘要:
A step-type training machine in which the exerciser trains using a predetermined load while detecting the pulse of the exerciser, and in accordance with data (e.g. the age, sex and weight) inputted before the training and various data (e.g. the exerciser's pulse) during the training, the step load is varied and controlled during the training so as to impart the optimum exercise load to the exerciser. The machine includes a frame; a plate for mounting various parts at a lower portion of the frame; a pair of crankarms each pivotally mounted by a pivot shaft on the plate and having a step member mounted on its one end movable up and down through a predetermined angle; an eddy current load device rotated by the swinging movement of the pair of crankarms; an input device for inputting individual data of the exerciser; a mechanism for measuring the pulse value of the exerciser; a detector for detecting the rotation frequency of the load device; a processor for extracting a control signal; and a display for displaying predetermined date extracted by the processing means.

A dry etching method, wherein a multilayer film including one selected from tungsten, molybdenum, and a silicide thereof, as the first layer, and polycrystal silicon as the second layer underlying is formed on a silicon oxide insulation film, a substrate having a mask pattern on the multilayer film is placed in a vacuum container, an etching gas is introduced into the vacuum container, and an electrical discharge is induced by applying an electrical field to the vacuum container, thereby anisotropically etching the multilayered film in accordance with the mask pattern. The method comprises the first etching step for etching the first layer by use of the first gas selected from fluorine, sulfur hexafluoride, and nitrogen trifuoride, or a mixture gas containing the first gas and the second gas selected from hydrogen chloride, hydrogen bromide, chlorine, bromine, and carbon tetrachloride, as an etching gas, and the second etching step for etching the second layer by use of the second gas, or a mixture gas containing the second gas and the third gas selected from an inert gas, nitrogen gas, oxygen gas, silicon tetrachloride gas and carbon monoxide gas, as an etching gas.
摘要:
A voltage comparator includes a coupling capacitor which receives at one terminal thereof two signals applied in a complementary fashion, an inverting amplifier having an input coupled to the other terminal of the coupling capacitor and having an output, and switch means coupled between the input and output of the inverting amplifier so as to be in parallel with the inverting amplifier. The duration of an auto-zeroing interval during which the switch means is conductive is maintained constant regardless of the period of the ON-OFF operation of the switch means.
摘要:
A data processing apparatus for processing data structured as records, each record including a number of fields. The processing consists of replacing the contents of specific fields in specific records. The apparatus has a memory for storing a record to be processed, a memory for storing data to be used in replacement processing, a register for storing information designating specific record fields to be processed, and a control section for successively reading out the stored record fields. As each field is read out, either the field data or the replacement data are transferred as output data from the apparatus, in accordance with the corresponding information in the aforementioned register.

摘要:
A capillary nib for pens is shaped from a thermoplastic resin bar and has a cross-sectional shape comprising an outer shell and a plurality of projections joined integrally at their bases to the outer shell at equal angular spacing intervals and projecting centripetally toward the center of the cross section, voids constituting principal capillary ink passages being formed between the projections, alternate projections extending fully to the center and being joined together. The thermoplastic resin bar is formed by extruding the resin in molten state though a die having a large number of orifices disposed in a specific arrangement thereby to form a plurality of filaments of the resin and causing the filaments to adhere longitudinally while the surfaces thereof are still substantially in molten state thereby to form the bar. Each passage or channel has substantially identical transverse width across its cross-sectional area.

A detection device includes: a detection member that includes an emission member emitting a beam toward a direction of a transportation path and a beam receiving member receiving a reflected beam reflected from a medium; a transmissive member that is provided to allow a regular reflected beam of the beam reflected from the medium to be obliquely incident thereto, and through which the beam emitted from the emission member is transmitted; and a multiple-layered antireflective film that is provided on the transmissive member, the antireflective film being formed such that a maximum value of reflectivity of a first incident beam incident at the same angle as an incident angle of the regular reflected beam becomes smaller than a maximum value of reflectivity of a second incident beam incident in the direction perpendicular to the transmissive member within a visible light wavelength range.
摘要:
In a start-up method of a single shaft combined cycle power plant, during a time period from when the gas turbine is started up to when rotation speed of the gas turbine reaches a rotation speed allowing self-sustained operation using the combustion gas, auxiliary steam from the start-up boiler is fed to the low-pressure steam turbine via the low-pressure turbine steam supply pipe by controlling valve opening degree of the auxiliary steam flow control valve. The low-pressure steam turbine generates a drive force. Speed-up control is performed in a unified manner for the gas turbine, the high-pressure steam turbine, the low-pressure steam turbine, and the power generator.
