Title: Ultrasonic flaw detection method for steel pipe, and apparatus therefor
Inventor: HASHIMOTO TATSUYA
IPC: G01N29/04
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To enhance the reflection intensity of ultrasonic waves from a defect and make reducible noises caused by echoes from a reinforcement of weld of a weld part and a weld metal or the like by setting the flaw detection refraction angle of ultrasonic waves sent into a steel pipe from an oblique probe to an angle with which the ultrasonic waves enter the plane defect perpendicularly. SOLUTION: A probe-selecting operating apparatus 11 operates an appropriate flaw detection refraction angle θ for detecting a plane defect 4 spreading in the thickness direction and axial direction within a weld part 3 in accordance with a thickness (t) and an outer diameter D of a steel pipe 1 to be inspected. Moreover, the apparatus selects an oblique probe 5 which can detect a defect with the flaw detection refraction angle θ and operates an incidence angle (i) of an ultrasonic wave 6 to an outer circumferential face 2 of the steel pipe 1. The probe-selecting operating apparatus 11 calculates the flaw detect refraction angle θ according to formula I from the thickness (t) and the outer diameter D.  At the same time, the apparatus calculates the incidence angle (i) in a propagation direction of the ultrasonic wave 6 within the oblique probe 5, that is, incidence angle to the outer circumferential face 2 of the steel pipe 1 according to formula II in which Vm, V are respectively a sound velocity of the longitudinal wave of the ultrasonic wave in an edge and a sound velocity of a transversal wave of the steel pipe 1.

IPC: G03G15/08
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To excellently keep the performance of carrying recovered toner, at all times and to efficiently recover the recovered toner to a toner recovering chamber, for maintaining cleaning performance by setting the repulsion of an elastic scraping member to such a degree that the heaping/sticking of toner on a rotary carrying member is inhibited. SOLUTION: A toner carrying means 4 is provided with the rotary carrying member 5 having an elastic rotary blade 7 and a scraping part, 8 which is provided in a housing 2, to obtain the elastic contact of the top end part, of the elastic rotary blade 7 and scraps the toner T stuck to the top end part, of the blade 7. Then, the repulsion F of the blade 7 is set to such a degree that the heaping/sticking of the toner T on the rotary carrying member 5 is blocked. In other words, various kinds of parameters are optimized to set the repulsion F to such a degree that the heaping/sticking of the toner T on the rotary carrying member 5 is inhibited. Thus, the toner T carried by the rotary carrying member 5 is surely carried to the side of the toner recovering chamber 2b, that is, the toner T never remains in a state where it is heaped on the rotary carrying member 5.

IPC: B60T8/30
Filed: 1985-12-03
Abstract: PURPOSE:To enhance the blending characteristic of brake hydraulic pressure, by preventing a plunger pressing force given by hydraulic pressure of a rear wheel cylinder from acting in the valve closing direction of a deceleration sensitive type brake hydraulic control valve when the latter is closed. CONSTITUTION:When an inertia force is applied to an inertia mass member 24 due to deceleration by braking, a force proportional to a lever ratio at the acting point acts upon a plunger 21 from a bush section 34a, and therefore, the plunger 21 receives a force in the valve closing direction. Further, the diameter of the plunger 21 is selected so that the hydraulic pressure Pr of a rear wheel cylinder is prevented from acting upon the plunger 21 in the valve closing direction when the valve section 31 is closed.

Title: Optical reception circuit
Inventor: ASAKURA NORIYUKI
IPC: H04B10/69
Filed: 1990-10-11
Abstract: PURPOSE:To extend the dynamic range and to eliminate the need for a fixed optical attenuator by providing a variable optical attenuator to an optical input section so as to control the attenuation of the variable optical attenuator in response to the optical power of a branched light thereby increasing a maximum light receiving level. CONSTITUTION:An optical input is given to a variable optical attenuator VAT 6 and its output is branched by an optical branching device PBR 7. Then an optical power mean value of one branched optical output is detected by an optical output power mean value detection circuit AVD 8 and it is compared with a reference value by a comparator 9. An optical attenuator control circuit ATC 10 controls the attenuation of the VAT 6 depending on the result of comparison. Through the constitution above, the optical input level is attenuated to an optical power less than the maximum light receiving level to prevent the optical power at the maximum light receiving level or over from being inputted to the APD 1. Thus, the dynamic range is extended and even when the reception circuit is used for short distance communication, no fixed optical attenuator is required.

IPC: G03G15/16
Filed: 1989-10-20
Abstract: PURPOSE:To prevent toner from being attracted to a transfer sheet on an upstream side in the rotating direction of a photosensitive body and to improve resolution by pushing the transfer sheet to the photosensitive body on the downstream side of the rotating direction by a conductive roller in the internal part of a transfer sheet holding cylinder composed of the sheet material of an insulating and soft material. CONSTITUTION:A transfer sheet 108 on a film roller 94 constituting the transfer sheet holding cylinder, which is composed of the insulating and soft material, is pushed to a photosensitive body 22 forming a toner image by a conductive roller 110 on the downstream side of the rotating direction in a contact point between the photosensitive body 22 and a roller 94. Then, the toner image is transferred to a transfer surface 108. Thus, the toner is prevented from being attracted to the transfer sheet 108 on the upstream side in the rotating direction of the photosensitive body 22 and since the transfer sheet is pushed with pressure at a certain degree so as not to crush the toner, a satisfactory transfer picture can be obtained.

Abstract: PURPOSE:To use only one reception antenna for the system and to reduce in space required for the antenna installation location by using signals of upper and lower side bands of the local oscillation frequency as 1st and 2nd transmission signals, respectively, after the conversion of the transmission frequency. CONSTITUTION:An intermediate frequency signal inputted to a transmitter input terminal 1 is branched into two by a distributer 2 and the signal is frequency-converted into signals of upper and a lower side bands of the local oscillation signal from a transmission local oscillator 10 at transmission frequency converters 4, 5. Then the high frequency and the low frequency signals are selected by 1st and 2nd band pass filters 8, 9 and the result is sent to space. The signal is received by a reception antenna 14, passes through a circulator 15, the signal component with the low frequency is a 1st reception signal and the component with the high frequency is reflected totally in the circulator 15, the high frequency component is selected via a circulator 16 and a band pass filter 18 and becomes a 2nd reception signal. Since one reception antenna is enough, the installation at a narrow space is attained while keeping a high transmission characteristic.
