Provided is a thermal flow meter including a conductive measurement tube including an inlet through which liquid enters and an outlet through which the liquid exits and including an internal flow passage extending along an axis, and a sensor substrate including a heating resistance wire and a temperature detecting resistance wire formed on a detection surface along the axis, and in the detection surface, an insulation area is formed where the heating resistance wire and the temperature detecting resistance wire are coated with a thin-film insulating material, and the insulation area is joined to the measurement tube along the axis.

Flow meter and method of manufacturing flow meter

A thermal flowmeter including a measurement tube that has an inflow port into which a liquid flows and an outflow port that allows the liquid which flows in from the inflow port to flow out, and has an internal flow passage where the liquid flows formed to extend along an axis, and a plurality of detection sections each of which has a heating resistor and a temperature detecting resistor along the axis and is provided at the measurement tube, and a control section that calculates a flow rate of the liquid flowing through the internal flow passage based on signals from the plurality of detection sections, wherein the plurality of detection sections are respectively provided with predetermined intervals left in a circumferential direction with the axis as a center.

Thermal flowmeter and method for determining weighting factor

Provided is a flow meter that determines a liquid flow rate based on temperature. The flow meter has a cylindrical measurement tube having an internal flow passage, and a temperature detecting substrate including a heating resistance element a temperature detecting resistance element formed on a detection surface thereof. The measurement tube has a flat surface facing the detection surface of the temperature detecting substrate, and a pair of recesses arranged so as to sandwich the internal flow passage at a position where the heating resistance element is arranged. The flat surface and the detection surface are bonded together to form two bonding area. A width of the first bonding area is narrower than a width of the second bonding area so that heat, transmitted through the measurement tube from the heating resistance element is increased.

Flow meter including increased measuring detection accuracy

A photosensitive material processing apparatus which performs, with high accuracy, the positioning of a negative table, an optical system supporting member, a guide member for photographic paper, a conveying member, a development portion, a drying portion and a cutting portion relative to each other on a base member by means of positioning members. As a result, a high quality image can be reliably obtained and the photographic paper can be accurately conveyed.

Photosensitive material processing apparatus

A piston head for an internal combustion engine is provided containing a polished nickel plated layer formed in the piston top and an anodized layer formed on at least the lower part of the uppermost piston ring groove in order to reduce the adverse affects of excessive thermal conditions on the member.

Piston for internal combustion engine

A four cycle internal combustion engine including a secondary intake system. The secondary intake system includes a pumping diaphragm actuated by pressure variation within the engine crankcase. The pumping diaphragm is in turn connected to the intake passage through a secondary intake passage to receive and expel air/fuel mixture toward the intake valving at appropriate intervals. A control valve control communication between the crankcase and the pumping diaphragm to restrict or allow actuation of the pumping diaphragm. An outlet also extends from the system to vent the crankcase at appropriate intervals.
