Inventor: YAMAMOTO YASUSHI
IPC: C21D8/10
Filed: 1991-04-22
Abstract: PURPOSE:To produce a square tube having strength as high as >=50kgf/mm<2> and also having earthquake resistance, refractoriness, and toughness at low temp without using expensive alloying elements in particular. CONSTITUTION:A tube of low carbon steel having a composition containing, by weight, 0.1-2.0% Mo and 0.01-0.15% Nb and/or 0.010-0.30% V is heated to (Ac3-200) deg.C. Square tube forming is started at (Ac3-200) deg.C and finished at a temp. between (Ac3-200) and (Ac3-200 deg.C. Subsequently, immediately after the forming or after air cooling, cooling is performed from a temp. between (Ac3-250) and (Ac3-70) deg.C at a rate of >=15 deg.C/sec, followed by tempering at 200-600 deg.C.

Title: Working pressure transmitting device for actuator
Inventor: NAKAMURA SHIGEFUMI
IPC: F02D21/08
Filed: 1982-05-27
Abstract: PURPOSE:To protect an actuator from positive pressure, by providing a one way valve preventing transmission of the positive pressure to an actuator by connecting pressure within a duct with the atmosphere only when the former is in the positive pressure in the midst of a pressure transmission duct between a pressure signal source and the actuator. CONSTITUTION:As a connecting hole 15 with the atmosphere is closed by a valve 14 of a one way valve 12 through negative pressure by generating negative pressure at a port 9 according to the opening of a throttle valve 8, in a normal operation range where a supercharger 3 does not actuate, the negative pressure is led into the negative pressure chamber 11 of an EGR valve 5 through a hose 10. When the led negative pressure overcomes resistance of a spring 13, a diaphragm 16 is raised, a duct 7 is opened by a valve 6 and part of exhaust gas is fed to a suction air pipe 4 through an exhaust pipe 2, a hose 20, the duct 7 and a hose 21. On the one hand, in an operation range where the supercharger 3 actuates, the suction air pipe 4 and the port 9 become positive pressure. In this instance, as the valve 14 is opened and the positive pressure is released through the connecting hole 15 with the atmosphere, transmission of the positive pressure to the negative pressure chamber 11 is prevented.

Abstract: PROBLEM TO BE SOLVED: To enable fast inspection of defects by determining parameters of a light source distribution function with a limited volume of calculation. SOLUTION: In a defect inspection method in which the surface of an object is irradiated with light at an observation point to inspect the presence of a defect at the observation point based on a plurality of luminance values obtained by measuring the reflected light, among parameters of the light source distribution function indicating the above mentioned luminance values, approximation functions as regression models are separately generated for the first parameter indicating peak values of the light source distribution function, the second parameter indicating an expanse of the base of the light source distribution function and the third parameter indicating a deviation of the peak values.  Regression coefficients of the respective approximation functions are determined by a regression analysis using the parameters thus obtained as purpose variables and the plurality of luminance values as description variables (S4, S6 and S8). Parameters are determined by the approximation functions using the plurality of luminance values measured per arbitrary observation point and the above- mentioned regression coefficients to inspect the presence of a defect at the observation point based on the parameters.

Inventor: FUIRITSUPU KOARIE
IPC: B64D45/08
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To enhance passage follow-up accuracy by providing a means to display on a collimator two inclined scales for a takeoff and a homeward touchdown which symmetrically incline along an X arm placed on an artificial skyline and cross each other by a value of a pitch attitude called a safe pitch attitude to be maintained when an engine runs into trouble. SOLUTION: An aircraft flies in a roll attitude of zero, and its wings are a flat shape in which half diameters 10 and 11 of a local horizontal line are completely lines up with wings of an aircraft model 2. Its pitch attitude is discriminated by indicators 12 and 13. It is larger than a safe pitch attitude to be maintained when an engine runs into trouble. The fact that the aircraft flies along a positional inclination of 5 degrees can be understood from a relative position of a ground speed vector 4 to inclined scales 7 and 8 for a takeoff and a homeward touchdown. The fact that the aircraft takes a course of 180 degrees on a nose azimuth scale can be understood from a relative position of a sign 4 of a 'ground speed vector' to an artificial skyline 3 and its nose azimuth scale.

IPC: B60T8/72
Filed: 1985-04-25
Abstract: PURPOSE:To make it possible to control the anti-skid operation of a vehicle with a high degree of accuracy, by estimating the frictional coefficient (mu) of a road surface in accordance with the difference between the peak value of false speed of the vehicle body and the last time peak value, and the lapse time thereof so that the deceleration of the wheel speed and the detected level of slips are changed in accordance with the frictional coefficient. CONSTITUTION:A selecting means 6 detects the highest one among outputs from vehicle wheel detecting means 5a through 5c for detecting the speeds of wheels 1a through 1c. Further, a false vehicle body speed subtractor 7 subtracts a predetermined amount from a false vehicle speed one control period before, and a false vehicle speed determining means 8 compares the output of the subtractor 7 and the output of the selecting means 6 to determine the higher one as a false vehicle body speed. Then, a road surface frictional coefficient (mu) estimating means 9 detects the peak value of the false vehicle body speed to obtain the deceleration of the vehicle body in accordance with the difference between the present peak value and that of the last time and the lapse time thereof, the thus obtained value being determined as the frictional coefficient(mu) of the road surface. Further, the anti-skid control is changed to exhibit such a trend that the lower the frictional coefficient (mu) of the road surface, the lower the braking pressure becomes.

IPC: H03M1/10
Filed: 1979-07-20
Abstract: PURPOSE:To secure an automatic control for the shift of both the offset and the gain, by setting both the offset calibration cycle and the gain calibration cycle. CONSTITUTION:Controller 24 indicates the execution of both the offset and gain calibration cycles prior to the A/D conversion of the original analog input signal. In other words, switch 12 is first turned to the earth side, and D/A converter 26-1 performs the successive A/D conversion via the earth level to store the offset amount in selector 25. Then switch 21 is changed over, and D/A converter 26-2 performs the successive A/D conversion to store the gain control amount in selector 25 via the partial pressure reference level of reference voltage 14. After this, the original A/D converting cycle is started to add each calibration value which is stored previously. In such way, the gain can be controlled automatically for both the offset and the gain.

Filed: 1994-04-28
Abstract: PURPOSE:To provide a bath room heating apparatus which senses the preparation of a bath and heats the bath room just before the bathing and puts the bath room at comfortable temperature in the bathing. CONSTITUTION:The temperature sensor 5 provided at the suction port 2a of a bathtub 2 measures the air temperature inside a bath room 4 when the bathtub 2 is empty. The temperature sensor 5 sends measured temperature to a controller 6 in every fixed time, and the controller 6 compares the measured temperature with the lowest temperature stored until then, and stores either lower temperature again. When hot water is poured in the bath 2, the temperature sensor 5 detects the higher temperature (hot water), and at the point of time when this detected temperature become higher than the second set value, it outputs a hot water signal. Furthermore, it compares the lowest temperature stored in the said way with the first set value, and if the measured temperature is lower than it, the temperature sensor outputs a room temperature. When these two signals are outputted, the controller 6 operates a pump 3, and jets hot water from a nozzle 1 to warm up the interior of the bath room 4.
