Title: Film thickness measuring method using fluorescent x-ray
Inventor: TAKESHIMA EIKI
IPC: G01B15/02
Filed: 1980-04-30
Abstract: PURPOSE:To realize a nondestructive and high-precision measurement for the thickness of film, by irradiating the X-rays to a painted metallic plate to measure the intensity of the secondary fluorescent X-rays given from the substrate metal and then calculating the thickness of painted film from the absorbing coefficient of the film. CONSTITUTION:The X-rays are irradiated to a metallic plate having a film of thickness (x) painted or laminated, and the intensity Nx is measured for the fluorescent X-rays of the substrate metal. At the same time, the intensity NO is measured for the fluorescent X-rays sent from a substrate metal having x=0 or having no painted film. Furthermore the X-ray absorbing coefficient mu is measured for the film. The background is referred to as Ninfinity  in the measurement corresponding to x=infinity , and thus the film thickness (x) can be calculated from a logic equation of x=1/mu{ln (N0-Ninfinity )-ln(Nx-Ninfinity )}. This result of calculation does not depend on the type of substrate metal. The diagram shows the examples of measurement concerning a relationship between the intensity of fluorescent X-rays and five different thicknesses of films on a zinc plate. In such way, a nondestructive and high-precision measurment is possible for the thickness of film.

Title: Device and method for reading recorded information from magnetooptical recording medium
Inventor: KIM DAE YOUNG
IPC: G11B20/14
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To read recorded information without an error by detecting a difference signal showing a level difference between an electric signal having a second level value and the electric signal of the second level value detected continuously to that when the electric signal is moved from a first level value to the second level value, generating a phase control signal, adjusting a clock signal and generating a read beam spot. SOLUTION: A phase control signal generator 1500 inputs an analog electric signal from a sample-and-hold means 1100 and a read bit signal from a bit line detector 1200, and detects the difference value between the second level values of the electric signals to form the phase control signal of the clock signal. The read bit signal and the electric signal are delayed by the period of the clock signal at least once, and a delay signal, the read bit signal and the signal before delay are processed. A channel clock generator 1400 adjusts the period of the clock signal based on the phase control signal so that a write-in mark on an optical disk 100 is irradiated by a laser beam spot.

Title: Vector composite type amplitude equalizer
Inventor: MIYAMOTO BUNICHI
IPC: H03H7/01
Filed: 1989-03-09
Abstract: PURPOSE:To obtain a vector composite type amplitude equalizer which is stable, inexpensive and which has less trouble for executing equalization by constituting the equalizer by means of a distributor, a composite unit, an attenuator, and a delay cable and specifying the delay time of the delay cable. CONSTITUTION:At the time of desiring a characteristic curve for attenuation vs. frequency which decreases with the increase of the frequency (abbreviated as decreasing toward the right), the distributor 1 is set to be an in-phase (or antiphase) type and the composite unit 2 to be the antiphase (or in-phase) type. When the center frequency of the transmission band of an input signal is set to be fm, the delay time tau1 of the delay cable 4 is set to be tau1 1/(0.8fm). At the time of desiring a characteristic curve increasing toward the right, both the distributor 1 and the composite unit 2 are set to be the in-phase type or the anti-phase type, and the delay time tau2 of the delay cable 4 is set to be tau2 1/(1.2fm). Since equalizing characteristic changes by varying the attenuation quantity of the attenuator 3, it does not take trouble to decide the equalizing characteristic. Since the equalizer can be constituted by the distributor 1, the composite unit 2, the attenuator 3 and the delay cable 4, the stable and inexpensive vector composite type amplitude equalizer can be obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of a main control part at the time of sending an Internet control message protocol(ICMP) by preparing two kinds of caches, i.e., a transfer cache having rewriting information and an ICMP cache having information for generating an ICMP packet. SOLUTION: A cache retrieving processing part in each of interface parts 31 to 33 is provided with a transfer cache having rewriting information for normal transfer as cache information to be stored in a cache table 201 and an ICMP cache having information for generating an ICMP packet to be added to a received packet at the time of transmitting an ICMP. When either one of the cache is hit in the processing part 9, an ICMP packet is generated and transmitted by an ICMP processing part 92 in the interface parts 31 to 33. Since it is unnecessary to execute ICMP generation processing by the main control part 2, the load of the control part 2 can be reduced.

Abstract: PURPOSE:To produce a cylinder liner for an internal-combustion engine formed with crescent-shaped ruggedness on the outside circumference by punching many small circular holes on the outside circumference of a hollow cylinder in the axial direction thereof then machining the outside circumference. CONSTITUTION:Many small holes 4 are punched apart from each other on the same circumference 3 in the outside circumference 2 of a hollow cylinder 1 made of an iron alloy. The cylinder 1 is rotated and the outside circumference 2 is machined to make grooves having each partly notched circular section so that longitudinal projections 5 between each adjacent grooves are somewhat widened at the outermost circumference of the cylinder; the projections are batched by oblique lines. The longitudinal grooves 4 having narrowed slits at the circumferential surface of the sylinder have successively widened arcuate spaces and are made formed between the longitudinal projections 5. The resulted cylinder liner is then inserted in a crank case 6 made of an alumina alloy. The gas 7 generated in the case 6 in this case is released to the outside of a casting mold through the grooves 4, and since the grooves 4 gnaw in the case 6, both are adhered tightly and firmly to each other.

Title: Air-fuel ratio control system for internal combustion engine
Inventor: TAKAHASHI ATSUSHI
IPC: F02D41/02
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of running performance of an internal combustion engine or emission due to deviation in the control gain of an air-fuel ratio feedback correction from an optimal value. SOLUTION: If the control gain of an air-fuel ratio feedback correction deviates from a optimal value due to piece-to-piece difference of an engine 11, wherein the fuel is injected and supplied directly into a combustion chamber 16, the running performance is deteriorated based on increase of torque fluctuation following such a deviation, or the emission is deteriorated based on delay in the air-fuel ratio reaching to the ideal air-fuel ratio following the deviation. However, if the torque fluctuation is increased due to the deviation of the control gain from an optimal value, control gain is modified according to the degree of the torque fluctuation. As a result, deterioration in the running performance following the increase of the torque fluctuation is suppressed, so that deterioration of both running performance and emission can be made compatible.

Title: Engine control device
Inventor: SASAKI MASAHIRO
IPC: F02B1/04
Filed: 1988-03-12
Abstract: PURPOSE:To maintain excellent performance of acceleration by constituting a device deciding an acceleration correction for whether it is proper or not and correcting the acceleration correction in accordance with the decision by the time from the point of time controlling an engine to be accelerated till a detecting result of air-fuel ratio by an O2 sensor changes from the lean to the rich. CONSTITUTION:When an engine 1 is controlled to be accelerated, a detecting signal by an O2 sensor 5 changes once to the lean thereafter to the rich by a response delay or the like in a fuel supply system for the response in an intake air system. Now when assumed T in this time for time after the engine is controlled to be accelerated till it changes into the rich, this time T shows a sufficient correlation for an acceleration response. Then detecting this time T, thus correcting an acceleration correction, an optimum correction condition can be always maintained.
