摘要:
Additional information, composed of characters, images, voice, etc., is converted into two-dimensional codes and then converted into a visible additional image to be embedded. The additional image is embedded in a full-color main image in a state of invisibility to produce a composite image. The composite image is recorded on a non-electronic medium such as paper or on an electronic medium, such as a memory on a personal computer, over the Internet. The embedded additional image is extracted from the composite image recorded on the recording medium and the additional information is reproduced.
摘要:
An evaporated fuel treatment apparatus having a correction checking means for detecting the state of change in the internal pressure of the fuel tank when the fuel tank is closed after being placed under atmospheric pressure, a leakage checking means for detecting the state of change in the internal pressure of the fuel tank when the fuel tank is closed after being placed under a negative pressure, and a judgement means for judging the presence or absence of leakage in the fuel tank on the basis of the detection results obtained by the leakage checking means and the correction checking means. The apparatus includes calculating means for calculating the amount of fuel consumption at the time of correction checking and the amount of fuel consumption at the time of leakage checking, and judgement prohibiting means for prohibiting a judgement of the presence or absence of leakage from being made by the judgement means in cases where the amounts of fuel consumption calculated at the time of correction checking and at the time of leakage checking are substantially different. As a result, a judgement of the presence or absence of leakage in the tank system is prevented from being performed in cases where such a judgement might be inaccurate.
摘要:
An evaporated fuel treatment apparatus that has a leakage checking means that detects the conditions of change in the internal pressure of the fuel tank when said fuel tank is closed after being placed under a negative pressure, and a judgement means that judges the presence or absence of leakage in the fuel tank on the basis of the detection results obtained by the leakage checking means and correction checking means. The apparatus further includes a pressure variation checking means which detects the degree of pressure variation in the fuel tank, and then opens the fuel tank to the atmosphere and judges whether or not the pressure inside the fuel tank has dropped. Judgement prohibition means is provided that prohibits a judgement of the presence or absence of leakage from being made by the judgment means in response to a judgement by the pressure variation checking means that the pressure has dropped. Accordingly, a judgement of the presence or absence of leakage in the tank system is prevented from being performed in cases where such a judgement might be inaccurate.
摘要:
A plane transformer has both a primary plane coil and secondary plane coils fitted in a fitting groove formed on a substrate composed of a magnetic substance. At least either of the primary plane coil and the secondary plane coils is separated into two, so that an output voltage is variably controlled by changing the numbers of turns of the primary and secondary plane coils. The plane transformer can be small in size and thickness, reduces generated heat, and hardly emits electromagnetic noises.

A television receiver comprising an information extracting circuit for extracting information from a format or content of an input video signal, a video signal processing circuit for processing this video signal by a program or data, a memory for storing the program and data, a CPU for controlling, operating or driving these elements, and a display device for displaying an image. The video signal processing circuit can, under the control of the CPU, decode the signal, correct or set the picture quality such as gradation and sharpness, or adaptively process an on-screen display based on the input video signal. The television receiver is also able to adaptively extend the functions of the television receiver corresponding to various signal formats.

A receptacle optical module including a fixed housing adapted to be fixed to a mother board (substrate); an optical semiconductor assembly having an optical semiconductor chip for performing conversion between an optical signal and an electrical signal; a plurality of lead pins fixed to the fixed housing for mechanically fixing the fixed housing to the mother board and electrically connecting the optical semiconductor chip to the mother board; a movable housing pivotably provided on the fixed housing for supporting the optical semiconductor assembly; and a receptacle mechanism for detachably holding an optical connector in the movable housing so as to optically connect the optical semiconductor chip to the optical connector. With this configuration, the movable housing for supporting the optical semiconductor assembly is pivotably provided on the fixed housing, so that the optical connector can be easily attached/detached, and possible bending of the lead pins due to attachment/detachment of the optical connector is suppressed.

A matte paint film includes a synthetic resin component as a paint film forming primary element, and silica particles having an average particles size D.sub.1 in a range of D.sub.1 .ltoreq.2 .mu.m and synthetic resin particles having an average particle size D.sub.2 in a range of 8 m.ltoreq.D.sub.2 .ltoreq.50 .mu.m as a matting agent. The weight proportion Pw of matting agent incorporated per 100 parts by weight of the synthetic resin component is set in a range of 20 parts by weight.ltoreq.Pw.ltoreq.100 parts by weight. The weight ratio Wr (W.sub.1 /W.sub.2) of the weight W.sub.1 of silica particles incorporated in the matting agent to the weight W.sub.2 of synthetic resin particles incorporated in the matting agent is set in a range of 20/80.ltoreq.Wr.ltoreq.70/30, and the thickness t of the paint film is set in a range of 8 .mu.m.ltoreq.t.ltoreq.30 .mu.m. A 60.degree. incident ray L.sub.1 is absorbed and/or irregularly reflected mainly by the silica particles in the film surface. On the other hand, a 85.degree. incident ray L.sub.2 is irregularly reflected and/or absorbed mainly by the synthetic resin particles partially protruding on the film surface and the silica particles deposited on the surfaces of such synthetic resin particles.

摘要:
A quinoline derivative represented by general formula (1), a medicinally acceptable salt thereof, and a remedy for cardiac diseases containing the same: ##STR1## [wherein ring A represents a furan, dihydrofuran or dioxolane ring, and R.sup.1 represents an aminoalkyl group].The compound (1) has a positively inotropic effect on myocardia and an antiarrhythmic effect, and can dilate blood vessels without extremely increasing the heart rate. Therefore, a remedy for cardiac diseases containing the same as the active ingredient is remarkably useful for treating cardiac insufficiency, arrhythmia, and so forth.
