Title: Air-fuel ratio control device for internal combustion engine
Inventor: DEGUCHI RYUICHI
IPC: F02D41/14
Filed: 1989-06-12
Abstract: PURPOSE:To reduce an NOx increment due to lean burn by periodically controlling a control air-fuel ratio to be at the vicinity of a theoretical air-fuel ratio, using an self-excited control waveform when the operation mode of an engine is judged to be in a lean air-fuel ratio operation mode. CONSTITUTION:An air-fuel ratio sensor 13 is fitted at the upstream side of a catalytic converter rhodium 12 provided in the exhaust passage of an internal combustion engine. Also, an operation mode judgement means A is provided for making judgement as to whether the engine is in a theoretical air-fuel ratio feedback operation mode a1 or in a lean air-fuel ratio operation mode a2. When the engine is judged to be in the operation mode a1, the operation B of an air-fuel ratio correction amount is made, depending upon output from the air-fuel ratio sensor 13, and the operation C of the central value of correction values is made. On the other hand, when the engine is judged to be in the operation mode a2, the generation D of a self-excited control waveform is made mainly about a value obtainable via the shift of the aforesaid central value toward the lean side by the predetermined value. In addition, the air-fuel ratio of the engine is adjusted with an air fuel ratio adjustment means E, depending upon the air fuel ratio correction amount or the self-excited control waveform.

Inventor: MATSUO MASAYUKI
IPC: G01N23/223
Filed: 1993-06-18
Abstract: PURPOSE:To realize highly accurate spectroscopic analysis by correcting the error in the measurement of intensity of fluorescent X-rays caused by the fluctuation in the total weight of samples. CONSTITUTION:The intensity of fluorescent X-rays is measured for a plurality of types of glass bead having identical dilution ratio and different total weight of sample.

Title: Method for removing dissolved oxygen in water
Inventor: FUJIWARA GORO
IPC: C02F1/28
Filed: 1986-06-24
Abstract: PURPOSE:To efficiently adsorb and remove the dissolved oxygen in water to be treated at a low cost without exerting any adverse influence at all to the ensuing process by passing said water to an oxygen adsorbent. CONSTITUTION:The dissolved oxygen in the water to be treated is adsorbed and removed by passing said water through the oxygen adsorbent. The execution of this method is more effective if the dissolved oxygen is preliminarily removed from the water to some extent by a deaerator. For example, an ion exchange resin material bonded and reduced with copper or copper compd. is preferably used as the oxygen adsorbent. As a result, the dissolved oxygen in the water is efficiently removed at a low cost without exerting any adverse influence at all to the ensuing process.

Title: Float valve with vibration-preventing streamlining plate
Inventor: KITSUTAKA YUTAKA
IPC: F16K31/18
Filed: 1990-06-06
Abstract: PURPOSE:To prevent generation of vibration of a main valve body and noise caused by the vibration by providing a streamlining plate for guiding fluid to a fluid outlet by a process of avoiding collision of at least the most flow of fluid, flowing from a fluid inlet toward the fluid outlet, against the external surface of the main valve body. CONSTITUTION:A streamlining plate 12 is composed of metal-made plate member, bent in a circular are shape in its cross section, with many small holes 12a... formed therein and mounted to the periphery of a valve box seat 10 through a bracket 13 opposedly to a position comparatively near the external surface 4B of a main valve body 4 and on a lower part of a cylinder 3. When the constitution is thus provided, fluid (arrow mark A1), flowing in from a fluid inlet 2 at opening time of the main valve body 4, collides against the straightening plate 12, and the most of the fluid is streamlined into a flow as shown by an arrow mark a1 and guided to a passage 14. On the other hand, partial fluid facing to the small holes 12a... of the streamlining plate 12, after the pressure is reduced, collides against the external surface 4B of the main valve body 4 at a low pressure flow as shown by an arrow mark a2. In this way, vibration of the main valve body 4 and a noise caused by this vibration can be surely prevented from being generated.

Filed: 1983-08-11
Abstract: PURPOSE:To increase the utilization efficiencies of the fuel and the oxidant by preventing any gas leakage from the joint area between a gas separator and an electrolyte-holding body or an electrode by forming concaves and convexes on the peripheral area of the gas separator and on at least one of the peripheries of the electrolyte-supporting body and the electrode so as to bring them into close contact with each other. CONSTITUTION:Concave grooves 5a are formed on a gas separator 4 for separately supplying an oxidant and a fuel while convex stripes 5b are formed on an electrolyte-holding body 1 or an electrode which is to be brought into contact with the gas separator 4 in such a manner as to connect the concave grooves 5a and convex stripes 5b to each other. In another method, convex stripes 5b are formed on the gas separator 4 and caused to encroach upon the electrolyte-holding body 1. The height of the convex areas or the depth of the concave areas is adjusted to be around 0.1-0.5mm.. Owing to the above constitution the gas separator 4 and the electrolyte-holding body 1 are made in close contact with each other and the oxidant or fuel does not leak out from the fuel cell into the external atmosphere. Consequently, a high generation efficiency and a high performance of the fuel cell can be maintained for a long time.
