Title: Method and apparatus for electromagnetic flaw detection
Inventor: SHINGIYOKU MIKIO
IPC: G01N27/83
Filed: 1988-02-19
Abstract: PURPOSE:To recognize a flaw on the basis of a pattern with high accuracy, by simple constitution such that a flaw detection probe is relatively moved with respect to the surface of an object to be inspected and the flaw detection output at each flaw detection position of the object to be inspected is subjected to image processing. CONSTITUTION:A high frequency AC magnetizing yoke 15 is mounted in the rotary frame revolving around the path line of a steel pipe 1. The yoke 15 is mounted so that a flaw detection probe 18 for detecting the leaked magnetic flux generated owing to the flaw of the steel pipe 1 holds a definite distance with respect to the steel pipe 1. An image processing apparatus 41 takes in the output of each search coil mounted in each probe 18 through a rotary transformer 42 and a probe signal detector 43, and also takes in the output of a rotation detector 31 through a trigger generator 44 to transmit such a cycle that each probe 18 makes one revolution, for example, with respect to the steel pipe 1. By this constitution, for example, the apparatus 41 applies binary image processing to the flaw detection output at each flaw detection position of the steel pipe 1 continuously detected by each search coil and extracts the flaw of the steel pipe 1 to make it possible to display the same on a display device 45.

Title: Ultrasonic flow meter
Inventor: WATANABE HAJIME
IPC: G01P5/01
Filed: 1981-03-12
Abstract: PURPOSE:To measure an extremely low flow rate by supporting an ultrasonic transmitter and a receiver with a sound absorbing material at a prescribed facing angle. CONSTITUTION:An ultrasonic transmitter 1 and a receiver 2 are stuck to a base plate 12 at 160-170 deg., preferably 167 deg. opposing angle theta, and the base plate 12 is coupled with a sound absorbing material 13 having a low elastic modulus. As a result, when facing distance l between the transmitter 1 and receiver 2 varies, the influence of a standing wave is eliminated and the adjustment of an oscillating circuit 3 which drives the transmitter 1 is facilitated; and further the receiver 2 obtains a signal stable against slight variation in oscillation frequency.

Title: Beam shaping device and optical pickup using the same
Inventor: MORI TAIICHI
IPC: G11B7/135
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To realize miniaturization of an optical pickup by providing first and second shaping devices to shape an intensity distribution of a light emitted from a light source from an elliptic shape into a circle. SOLUTION: A pair of a first shaping device 2 and a second shaping device 3 expand a beam in an X direction. For example, when a junction surface of a light source 1 is positioned in an X-Z plane, an intensity distribution of a beam at a far point, which has an elliptic shape with a longer axis thereof in a Y direction after emitted from the light source 1, becomes substantially a circle after passing the first shaping device 2 and the second shaping device 3 since the beam is expanded in the X direction.  Thus, before a diameter of a light emitted from the light source 1 and guided to a recording medium while being diffused gets larger, the light is incident on the first shaping device 2 and the second shaping device 3, whereby sizes of the first shaping device 2 and the second shaping device 3 can be reduced, which then results in miniaturization of an optical pickup incorporating these components.

Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To precisely set the initial height of a torch regardless of the waviness and the deformation developed on a material to be worked and the internal distance between the torch and a sensor, at the time of starting the cutting-off or welding, etc., of the material to be worked by using the torch of a plasma torch, laser beam torch, etc. SOLUTION: An elevating/lowering bracket 4 is lowered by driving an elevating/lowering motor 2 and fitted to a guide member (guide bracket) in the vertical direction, and the tip part of the torch 1 energized downward is brought into contact with the material to be worked with a spring. Since the torch 1 is stopped by contacting with the material to be worked and the elevating/lowering bracket 4 is continuously lowered, the relative shift is developed between both. The shifting is detected by the sensor, and the elevating/ lowering motor 2 is stopped and thereafter, the elevating/lowering bracket 4 is elevated to the preset height.

Abstract: PURPOSE:To obtain a high output amplifier synthesizer circuit capable of removing drape, in obtaining high output by synthesizing the outputs of two amplifiers, by providing a phase shifter, of which the frequency characteristics are adjusted and set, between one amplifier and a synthesizer circuit. CONSTITUTION:In order to obtain sufficient output in a total solidified high output amplifier, charp pulses are parallelly amplified by two transistor amplifiers 5, 6 and synthesized by a synthesizer circuit 8. At this time, a (pi/2+theta) phase shifter 9 is provided between one transistor amplifier 6 and the synthesizer circuit 8. Herein, theta is adjusted and set so as to take a value proportional to frequency. If this phase shifter 9 is used, the input signals of the input ports 1, 2 of the synthesizer circuit 8 are different by pi/2+theta radian and, as a result, the output signal of an output port 3 comes to one modulated in amplitude in proportion to theta. Therefore, the output of the port 3 has frequency amplitude proportional to frequency.

Title: Fuel controller of internal combustion engine
Inventor: SASAKI TAKEO
IPC: F02D41/34
Filed: 1988-02-18
Abstract: PURPOSE:To supply the specified quantity of fuel at the desired timing by calculating the quantity of fuel to be supplied synchronously with the change-over of an injection timing. CONSTITUTION:In a controller 30 the driving means of an injector 16 predicts the driving period of the injector 16 on the basis of the variation in driving time. When the predicted driving period is more than the specified time and an internal combustion engine 1 is in the specific running state, such as high speed running state, the injector 16 is driven at earlier timing, but when not, said injector 16 is driven at later timing. Since the quantitative calculation for fuel is executed immediately after the rise-up of the signal from a crank angle sensor 17, the calculation is synchronized with the change-over of an injection timing, whereby executing the proper air-to-fuel ratio control without shortage in fuel supply caused by a delay of the quantitative calculation for fuel.
