Title: White smoke reducing device for diesel engine
Inventor: MORI YASUO
IPC: F02D9/04
Filed: 1990-04-10
Abstract: PURPOSE:To reduce generation of white smoke by providing a throttle valve to close one part of an intake passage and an opening/closing valve to close one part of an exhaust passage according to working signals output from a sensor. CONSTITUTION:When an engine 1 is operated, a signal corresponding to cooling water temperature at the time is sent from a temperature sensor 9 to a controller 8. The controller 8 computes the temperature of the engine 1 based on the supplied signal from the temperature sensor 9. When the computed temperature is judged, for example, to be under 50 deg.C, working signals are respectively supplied to a throttle valve 4 and an opening/closing valve 7. Both the throttle valve 4 and the opening/closing valve 7 keeping full open condition until the time are operated to close to be one quarter opening for example, fresh air quantity supplied to the combustion chamber is limited, back pressure is raised, and hence residual gas quantity in the cylinder is increased. Hereby, air excess ratio in the combustion chamber is not increased more than need, cylinder temperature is raised to promote vaporization of injected fuel, fuel consumption is improved, and generation of white smoke is restrained.

Title: Ultrasonic probe
Inventor: SEO IKUJI
IPC: A61B8/00
Filed: 1979-07-25
Abstract: PURPOSE:Not only to increase the receiving sensitivity of the ultrasonic wave but to shorten the time duration of the received pulse, by setting the acoustic impedance of the acoustic matching component to 0.5-0.8 times as much as the geometric mean value of the acoustic impedance of the piezoelectric oscillator and the test subject. CONSTITUTION:Acoustic matching layer 3 is provided on the single surface of piezoelectric oscillator plate 1 via the 1st metal electrode 2a; and packing component 4 is provided on the other surface via the 2nd metal electrode 2b respectively. Maching layer 3 secures an acoustic matching between plate 1 and test subject 5, at its thickness is set to lambda/4 (lambda: ultrasonic wave generated from plate 1). Component 4 absorbs the extra ultrasonic waves generated from plate 1 to shorten the pulse duration of the ultrasonic wave. Here the acoustic impedance of 0.5-0.8  times as much as the geometric mean value of the acoustic impedance of plate 1 and subject 5 is set for the lambda/4 matching layer 3. As a result, nearly the maximum  receiving sensitivity can be obtained, at the same time minimizing the time duration of the received pulse.

Abstract: PURPOSE:To enable an image to be corrected without being affected by the difference between a main scan and a subscan mechanisms, by correcting the image by an MTF correcting filter in which characteristics in a main scan and a subscan directions are set independently. CONSTITUTION:An MTF(modulation transfer function) correcting filter FC has band-pass characteristics in the main scan and the subscan directions as shown in figure A. For example, the MTF correcting filter is constituted so that it has the frequency characteristics with the inverse 1/H(u) of a function H(u) respectively in the main scan and the subscan directions. At such a time, it is assumed that the H(u) is a function obtained by the Fourier transform of a spreading function h(x) in the main scan direction. In this way, the enhancement of the signal component of the Nyquist frequency can be prevented. Simultaneously, influence due to the periodical fluctuation of a level caused by the use of amplifiers 22a and 22b for even-th scan and odd-th scan in the main scan direction, can be eliminated. Also, since a low frequency component passes through the MTF correcting filter as it is, and also, the signal component in the neighborhood of the frequency component of the peak of a gain is enhanced, the blur of an image can be corrected. Also, a variable power in the main scan direction is performed at a main scan variable power part 25. but the variable power in a subscan direction is performed by changing the scanning speed of an optical system.

Title: Composite piezoelectric filter
Inventor: NAKAJIMA YASUO
IPC: H03H9/58
Filed: 1978-08-03
Abstract: PURPOSE:To reduce the reduction in the band width of crystal filter and to increase the guaranteed attenuation, by the cascade connection of the ceramic filter and crystal filter having the same center frequency. CONSTITUTION:The cyrstal filter 1 and the ceramic filter 2 having the same center frequency are in cascade connection. The specific band width of the composite piezoelectric filter is almost the same as the filter 1 since the filter 2 has wider band than that of the filter 1, and the guaranteed attenuation is the sum of the two filter values. Further, taking the upper limit cut off frequency and lower limit cut off frequency of the filter 2 at 1 dB down as f1 and f2, those of the filter 1 at 3 dB down as f3 and f4, if f1>f3, f2<f4, are kept at operating temperature, the band width of the composite piezoelectric filter is kept almost the same as the case with only the crystal filter, allowing to increase the guaranteed attenuation.

Title: Descrambling method
Inventor: MORI HITOSHI
IPC: H04N7/169
Filed: 1987-04-17
Abstract: PURPOSE:To eliminate the step due to the effect of horizontal tilt caused at the reception side on the picture puality subjected to descramble by applying internal correction to the horizontal tilt caused in the video signal part to be scrambled based on the horizontal tilt quantity. CONSTITUTION:A difference from a dotted line part at the sample point of time of each sampling clock till the pedestal signal part is a tilt quantity in the horizontal direction. Thus, the horizontal tilt quantity is calculated by a tilt correction circuit 108 during optional horizontal scanning period where no video signal component in the vertical blanking period exists. The tilt calculated by the tilt correction circuit 108 is held in the inside of the circuit and inverse correction is applied to the sampling value with respect to the video signal attended with the horizontal tilt. As a result, the video signal of digital signal form passing through the tilt correction circuit 108 is a signal without horizontal tilt. Thus, the best picture quality is always obtained as the decoded picture quality.

Filed: 1981-06-23
Abstract: PURPOSE:To increase filtering capacity, by respectively forming the 1st oil paths at the one end side and the circumference of a filter element wit rolled paper shape and the 2nd oil paths at the other end side of it and in the inside of a cored body, in an oil filter used for the lubricating system of a motor car engine. CONSTITUTION:Oil, transferred by a pressure from the direction of the arrow, is supplied to the 1st oil path A through an oil inlet port 91c to push open a member 13 against an elastically reactive force of a spring 14, and is passed through the inside of an element 1 from the upper end and the outer circumference of the element 1 to be filitered. Next, the oil enters the 2nd oil path B through bottom surface of the element 1 and passes through the inside of a pipe 2, and then, is sent to an oil port 11 of an engine case 10. When the oil flow rate is increased by increasing an engine speed or the filtering flow rate is decreased by a clogging of the element 1 produced in itself, a clearance between a turn-up part 3d and the member 13 is produced against an elastic reactive force of a spring 7 to cause a by-passing of the oil. Accordingly, the high filtering efficiency is maintained over a long period of time.
