Title: Optical amplifier
Inventor: SHIMA MICHIKAZU
IPC: H04B10/2507
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical amplifier that amplifies an input signal light in a wide input dynamic range, without saturation to suppress the effect of wavelength dependence on a gain with respect to the optical amplifier that amplifies wavelength multiplexed signal lights altogether. SOLUTION: This optical amplifier consists of three optical amplifier sections 1, 3, 5 connected in cascade, an optical attenuation section 7 that adjust the power level of a signal light received by the optical amplifier section 3 for controlling the level of a signal light OUT which is outputted from the optical amplifier section 5 to be constant, and a scattering compensation fiber 8 provided between the optical amplifier sections 3 and 5. The optical amplifier sections 1, 3, 5 receive a constant gain control by automatic gain control AGC circuits 19, 39, 60 respectively. Since the gain of the optical amplifier section 1 at the first stage is decreased by adopting the 3-stage configuration for the optical amplifier sections, even if a signal light with a high power level is received, gain constant control is conducted without saturating the optical amplifier section 1.

Title: Gasoline engine equipped with exhaust intake valve
Inventor: TAKAGI YOSHIARI
IPC: F02M25/07
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To ensure safe combustion even if an EGR circulation rate is increased, reduce pumping losses and increase a fuel consumption rate by providing an exhaust intake valve in a combustion chamber and sucking exhaust gas into the combustion chamber through a valve different from that for mixture or air. SOLUTION: An exhaust intake valve 1 is provided in the combustion chamber of a gasoline engine, and this valve is opened/closed at the same timing for an intake valve 2. That is, during an intake stroke, mixture from the intake valve 2 and exhaust gas from the exhaust intake valve 1 are simultaneously sucked into the combustion chamber, and then stratified charge combustion is performed. By sucking the mixed gas and the exhaust gas into the combustion chamber through different ports, the generation of an independent swirl or tumble is facilitated, and the generation of a stratified intake gas between the mixture and the exhaust gas in the combustion chamber (mixture is collected near an ignition plug, and exhaust gas is formed in its outer side) is facilitated.  A ratio between the mixture and the exhaust gas is controlled to increase the amount of exhaust gas to the range of carrying out stable combustion.

Title: Solid state x-ray image convertor
Inventor: SHIMIZU YOSHINORI
IPC: G21K4/00
Filed: 1988-03-29
Abstract: PURPOSE:To improve drastically brightness and resolution, by laminating a first electrode layer of a transparent conductive film, i.e., a fluorescent layer, a non-transparent layer and photo conductive layer, and a second electrode layer by turn on a transparent substrate. CONSTITUTION:A solid state X-ray image convertor is constituted with multiple thin films laminated on a glass base plate 1. An AC voltage of some 400-500V is applied between a transparent electrode 2 and a second electrode. On the other hand, when an X-ray is irradiated to the convertor in this condition, a voltage applied to a luminescent layer goes high. Finally, when the voltage goes higher than a luminary voltage, a luminary brightness increases very rapidly. Because the luminary brightness is proportional to an intensity of the X-ray, the X-ray is converted directly into a visible photo image. In this situation, a thickness of a fluorescent layer is 0.5-1.0mum and that of a photo conductive layer is 2-5mum, that is, both are of very thin film structure and without any irregularity of layer thinkness and moreover a photo beam luminesced in the fluorescent layer is not scattered by particles so that and extremely high brightness compared to a conventional method can be attained.

Title: Ultrasonic distance measuring device
Inventor: DOI KOJI
IPC: G06F3/043
Filed: 1990-03-26
Abstract: PURPOSE:To accurately decide whether an input is regular or not and to prevent the wrong input by invalidating the measurement of distance when it is estimated the pressing force is less than a prescribed level. CONSTITUTION:A coordinate pointing device 1 is provided together with a sensor 2, a pen drive circuit 100, a driving waveform generating circuit 101, a tg/tp detection circuit 200, a counter circuit 201, a CPU 300, etc. Then a signal level is read out and at the same time the distance is measured between a vibration generating means and the sensor 2. Based on the relation between the result of the distance measurement and the signal level, the pressing force of the vibration generating means is estimated. Then the result of the distance measurement is validated only when the pressing force of the vibration generating means is larger than a prescribed level. Thus it is possible to evade the input of an extreme tilt state of the vibration generating means regardless of the distance relation between the vibration generating means and the means 2. Then the measurement of distance is always attained with the constant pressing force.
