Title: Motor current detecting circuit
Inventor: NISHIBE TAIJI
IPC: H02P7/06
Filed: 1993-02-18
Abstract: PURPOSE:To obtain a motor current detecting circuit which can detect the overload state of a motor quickly by suppressing the chattering of detection output due to the fluctuation of motor current effectively. CONSTITUTION:A hysteresis imparting circuit 30 imparts hysteresis characteristics, corresponding to the time integration value of the increment of a potential v2 (corresponding to the motor current value Im) over a reference value v1, to a comparator 14. When the current value Im of the motor 12 repeats increment and decrement at some width and increases with time as a whole, a hysteresis imparting circuit 30 causes the comparator 14 to generate such hysteresis characteristics as the amount of hysteresis increases with time depending on the time integration value of the increment of potential v2 exceeding a voltage set value v1. Consequently, output from the comparator 14 is reduced and the chattering of detection output is suppressed thus allowing quick detection of the overload state of the motor 12.

Title: Cordless telephone system
Inventor: MIZUMOTO TORU
IPC: H04M1/725
Filed: 1990-02-13
Abstract: PURPOSE:To attain normal and excellent talking even in simultaneous talking from slave stations by selecting an antenna gain depending on the strength of a received radio wave. CONSTITUTION:The electric field strength is discriminated by an antenna gain control circuit 10 depending on the electric field strength of a reception signal at a slave set 1 and the antenna gain is selected in response to the reception signal level. Thus, in the case of making simultaneous talking from plural slave sets 1, the slave set 1 close to a master set 31 does not give a strong electric field to the utmost to other slave set 1. Thus, excellent and simultaneous talking from plural slave sets 1 is attained independently of the distance of a radio line between the master set 31 and the slave set 1.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device with a document feeder constituted so that an image is formed on a paper by adjusting the feeding timing of a document and the supply timing of the paper by comparatively simple mechanical constitution. SOLUTION: A document image is read by moving the document to a document read part by a document feeder on a condition that the document read part is fixed at a position R. Then, the document image is formed on the carried paper at an image forming part. At this time, the feeding speed of the document is increased at previously decided fixed acceleration from a time point that the leading edge of the document is detected by an image edge sensor S3. When the feeding speed arrives at the target speed corresponding to image forming magnification, the target speed is maintained at least while the document is read. Then, the supply timing of the paper is decoded based on an arrival time T that the leading edge of the document obtained according to the image forming magnification arrives at the document read part from the sensor S3.

Abstract: PURPOSE:To cast continuously a deflectless billet free from foam and inclusions over the entire surface on the long and short side of a product, i.e., steel slab by conducting the swirling horizontal flow along the respective mold surfaces on the long and short sides in the molten steel surface part in a mold. CONSTITUTION:Continuous casting of a molten steel 4 cast into a mold for continuous casting of a steel slab is executed while the molten steel 4 in the mold 1 in contact with the mold surfaces on the long side is forced to flow horizontally by electromagnetic stirrers 2, 2 built respectively into both long side faces facing each other of the mold 1. Partition walls 9, 9 to bisect the spacing between both long side mold surfaces spaced from the respective short side mold surfaces of the mold 1 are immersed and installed into the molten steel 4 in the mold 1 to form the circumnutating flow passages of the horizontal flow. The swirling horizontal flow along the long and short side mold surfaces is thus induced in the molten steel 4 near the molten steel surface 5 in the mold 1.

Abstract: PURPOSE: Raw material steel for forging is added with V, and after forging the products are subjected to a specificaly adjusted cooling, thereby producing high- strength, high-toughness forged steel products without using refining process.  
     CONSTITUTION: Forging steel includes, C: 0.30 to 0.60%, Si<0.50%, Mn: 0.60 to 2.0%, V: 0.30 to 0.20%, sol Al: 0.02 to 0.06%, N: 0.008 to 0.02%, and if required Cr<0.50% or one or more of specific amount of S, Pb, Bi, Te, Se, Ce, and Ca, Mn%/C% being adjusted to more than 2. The steel material is, immediately after hot forging, adjustably cooled to a temperature just above the A 3 , at a cooling rate of 0.7 to 15°C/sec. After starting modification, the material is cooled to 500°C at a  rate of 0.2 to 15°. Such cooling process hinders the growing of austenite granules,  precipitating V carbide and V nitride in modifying period, which function as nucleus for ferrite modification to produce very fine structure of ferrite plus pearlite,  thereby providing high-strength, toughness, and malleability to as-forged products  without using refining process.
