摘要:
A reference electrode is formed of lead, zinc, tin, indium, cadmium, magnesium, or any alloy thereof. A pair of electrodes comprising the reference electrode and a responding electrode made of a conductive solid, when placed in oil, develop a potential difference varying with the acidity or basicity of the oil and thus enable the efficient determination of the acidity or basicity.

A fuel supply system for engines having a carburetor which has a float chamber and a vapor bleed passage connected to the float chamber, wherein a part of a fuel supply passage means for supplying fuel from a fuel tank to the carburetor traverses through the float chamber so that the fuel flowing through the fuel supply passage means absorbs heat from the fuel contained in the float chamber. The fuel entering into the float chamber releases volatile light components as vapor towards the vapor bleed passage while the liquid fuel contained in the float chamber becomes a more stable liquid due to the release of volatile components and the cooling effected by heat exchange with the fuel flowing through the fuel supply passage means.

A main metallic gasket body is formed by interposing an intermediate plate between two elastic metallic plates, each of which have a bead formed around combustion chambers. The intermediate plate is divided into two pieces, steps are formed by the two pieces, and spaced formed between the pieces are provided with thermal spray stoppers.
摘要:
A vaporization promoting apparatus for an internal combustion engine is disclosed, in which at least one electrode is disposed in an intake manifold, and the electrode and the intake manifold are respectively connected to a high voltage generator which is provided for forming an intensive electric field in the interior of the intake manifold, thereby vaporization of a fuel injected into the intake manifold from a nozzle of a carburetor is promoted by the intensive electric field.

A mechanism is provided whereby the opening of an automatic choke valve is controlled by means of pressure in a diaphragm chamber with the chamber being selectively communicated with a vacuum pickup tube or an atmospheric pressure pickup tube through operation of a solenoid controlled valve. A switch actuatable in response to vehicle speed and another switch actuatable in response to engine temperature operate to selectively connect the solenoid controlled valve to a power source thereby to determine the operating mode of the valve.

Disclosed is a fuel feed device of an internal combustion engine. The fuel supply conduit communicating the carburetor and the fuel tank is arranged in the carburetor for cooling the carburetor and for vaporizing the low boiling components in the fuel only when the temperature of the engine is higher than a predetermined level. The fuel flowing out from the fuel supply passage located in the carburetor is introduced into a low boiling component separator. In this separator, the low boiling components in the fuel are removed, and then the fuel consisting of the high boiling components is fed into the carburetor to prevent the occurrence of an abnormal fuel metering operation under a high-temperature condition.
摘要:
An internal combustion with an arrangement for heating the suction gases in order to promote the vaporization of the fuel contained within the suction gases is disclosed. In the arrangement, the exhaust gases exhausted from the engine are routed around fins formed on the exterior wall of the bottom floor of the intake manifold for receiving the heat of the exhaust gases, and a covering is provided for enclosing the fins of the intake manifold in a closed chamber which is defined between the covering and the exterior wall of the intake manifold. The covering is provided with inlet and outlet ports so as to introduce the exhaust gases into the chamber and so as to drain the exhaust gases from the chamber. The introduced exhaust gases heat the entire surface of each fin so that the heat of the exhaust gases is transmitted to the fuel within the suction gases thereby accelerating vaporization of the fuel.
摘要:
An apparatus for measuring an alignment accuracy between overlaid alignment marks formed to each of alignment mark portions on every plural chip units or exposure units arranged on a substrate to be measured, comprising: an XY stage running in a direction x and in a direction y while mounting the substrate; an illumination optical system for illuminating each of the alignment mark portions in a state where the XY stage runs in a direction x which is a direction of arranging the chips; a detecting optical system having an objective lens for collecting a reflection light in the running state obtained from the overlaid alignment marks, a focusing optical system for focusing the reflection light in the running state obtained from the objective lens, a scanning optical system for scanning reflection light image in the running state focused by the focusing optical system in a direction opposite to that of the running and a linear image sensor receiving reflection light image substantially in a static state being scanned in the opposite direction by the scanning optical system and converting them into image signal; and an alignment accuracy calculation device for measuring the alignment accuracy between the overlaid alignment marks at least for a direction perpendicular to the running direction based on the image signal converted by the linear image sensor.
摘要:
Disclosed is a fuel feed device of an internal combustion engine. A heating device is disposed in the fuel supply conduit communicating the carburetor with the fuel tank for vaporizing the low boiling components in the fuel. The liquid fuel containing bubbles of the fuel vapor therein is introduced into a low boiling component separator. In this separator, the low boiling components in the fuel are removed and then the liquid fuel consisting of the high boiling components is fed into the carburetor.
