Title: Heat exchanger using spiral flow of fluid
Inventor: TOMONAGA KATSUHIDE
IPC: F28F13/02
Filed: 1995-05-10
Abstract: PURPOSE: To improve the efficiency of heat transfer markedly by sending by a spiral-flow generator a spiral flow of a convertible fluid along the inner surface of a cylindrical heat-transfer wall provided with a passageway for heat-transfer medium. CONSTITUTION: A spiral tube 10a as a passageway for heat-transfer medium is provided in a thick-walled part of a cylindrical tube 10 and a heat-transfer wall is formed in a manner of making the heat-transfer medium flow back and forth longitudinally in the cylindrical tube 10. On the other hand, sectionally inside a cylindrical container 21 of a spiral-flow generator 20 stationary blades are radially arranged, through which a current of air from a blower 22 is passed, turned into a spiral flow, and sent into the cylindrical tube 10. The air thus sent flows along the heat-transfer wall toward the outlet and after undergoing heat exchange is blown out in a spiral flow from an exhaust port. This method improves the efficiency of heat transfer considerably and also facilitates the maintenance.

Title: Non-contact igniter
Inventor: YOSHIDA TATSUYA
IPC: F02P9/00
Filed: 1980-08-15
Abstract: PURPOSE:To prevent a four-cycle engine from excessively rotating or improve the output of a two-cycle engine in its rapid rotation, by accurately controlling the time of ignition at high rotational frequency. CONSTITUTION:The output of a pulser coil 1 is shaped by a flip-flop 4 and then supplied to two triangular wave generation circuits to attain a characteristic shown at (a) in the drawing. Since a capacitor 2 is connected to the pulser coil 1, delay by the time of charging is caused. For that reason, the angle of ignition is delayed as the speed of revolution rises. This results in preventing the excessive rotation of a four-cycle engine or improving the output of a two-cycle engine in its rapid rotation.

Title: Method and apparatus for active sound attenuation
Inventor: MAAKU SHII ARII
IPC: G10K11/16
Filed: 1989-04-28
Abstract: PURPOSE: To improve system performance by reducing a modeling range from the cut-off frequency of an input signal. CONSTITUTION: This device has a model input 40 from an input microphone or a transducer 42 and an error input 44 from an error microphone or a transducer 46 and is modeled by an adaptive filter model 38 for outputting a correct signal to an omnidirectional speaker or a transducer toward 48 for supplying cancel sonic waves, so that an error signal at the error input 44 can get closer to a prescribed value, such as '0'. The input signal is high-pass filtered by a high-pass filter 62 to the cut-off frequency of 4.5Hz. The cutoff frequency of a highpass filter 56 is kept at 45Hz. Thus, an adaptive modeling process for modeling the invertion of a plant and an input filter is further improxzed.

Title: Random access digital synchronous light wave number synthsizer
Inventor: BAANAADO GURANSU
IPC: H01S5/0625
Filed: 1990-05-01
Abstract: PURPOSE: To bring the laser bias current supplied to a laser nearer to the accurate value, with respect to a desired resonance frequency by incorporating a means, which selects one of the store values of a control signal for driving the laser in a desired oscillation frequency set. CONSTITUTION: When the characteristic curve of a laser drifts, the control circuit section of a feedback loop decides a control signal error and adds the error to the value of a restored control signal. A digital processor measures the value of the control signal error and deduces a new total control signal value, which is stored in place of the control signal value. When the digital processor decides to pull up an error control signal, the processor calculates new control signal values with respect to all the desired working frequencies and stores the new control signal values at an appropriate position in the processor for the next selection and use. As a result, the laser is controlled by the control signal value which generates a desired accurate working frequency.  Therefore, the laser bias current supplied to the laser can be brought nearer to the accurate value, with respect to a desired resonance frequency.
Patent JP-S5636071-A (JP)
Title: Sensor
Inventor: OOHASHI HIROSHI
IPC: G01V3/08
Filed: 1979-08-31
Abstract: PURPOSE: To detect the movement of an object in only approaching direction by providing an exciting wire and a plurality of sensing wires on both sides of the exciting wire, setting the induced voltage on the side closer to the object to be larger than the induced voltage on the remoter side, and inverting the phase of the induced voltage as the object approaches.  
     CONSTITUTION: On poles 4a and 4b sensing wires 3a and 3b are wired at a distance so that one sensing wire 3b is on the side closer to an object M to be sensed and the other sensing wire 3a is on the remoter side. The induced voltage of the sensing wire 3a is set to be smaller than the induced voltage of the sensing wire 3b by varying the distance. When the object M approaches to the sensing wires 3a and 3b, induced voltages VA and VB are produced, and the induced voltage of the sensing wire 3b decreases as the object M approaches. Consequently, the difference voltage VA-VB and the induced voltage VB of the sensing wire 3b are made to be in-phase. The outputs of limiters 6a and 6b enter between the output levels VH and VL, and the relay of a switching circuit 8 is actuated to be off. By the constitution, since the phase is inverted according to whether or not the object M exists under the sensing wires 3a and 3b, the movement of the object M in only approaching direction can be detected.

Title: Production of steel having high strength and high ductility
Inventor: SHINODA KENICHI
IPC: C22C38/00
Filed: 1983-06-23
Abstract: PURPOSE:To obtain a heat-treated steel provided with high strength, excellent ductility and toughness in a combined austempering method of a specifically composed middle and high carbon steel by stabilizing positively residual austenite. CONSTITUTION:A middle and high carbon steel contg., by weight, 0.40-1.10% C and 0.8-2.7% Si among the elements in the steel is held at a temp. region of the Ac3 point -Ac3 point of said steel +150 deg.C to austenitize the steel. The steel is then hardened from said temp. region to a temp. region of the Ms point -M80% point of the steel. The steel is thereafter heated from the state in which >=20vol% untransformed austenite is maintained to a temp. region of 300- 450 deg.C so that the tempering of martensite and the bainite transformation of the untransformed austenite is effected. The steel is at the same time cooled to an ordinary temp. by regulating the holding time in said heating temp. region in such a way that the residual amt. of the austenite stable at an ordinary temp. attains >=5vol%. The bainite transformation is interrupted by such regulation. The steel in which the three phases, martensite, bainite and residual austenite, coexist, is thus obtd.
