An information processing device generates web page data of a first window including a program causing a terminal device to execute an elapsed time determination process for obtaining first time information at a timing of a transition from the first window to a second window, obtaining second time information at a timing during which a process in the first window is executable in a state after the transition to the second window, calculating an elapsed time from a difference between the first time information and the second time information, and executing a predetermined process according to a comparison between the elapsed time and a threshold time. The information processing device executes a process for transmitting the web page data to the terminal device and causing the terminal device to present the web page data.

An expansion valve for reducing the quantity of material required for the valve body by contriving the arrangement of bolt fitting grooves. In the expansion valve (), displacement of a valve member driver () provided in the valve body () is transmitted to a valve member by a valve member drive rod () and the valve opening is altered to control the flow rate of the refrigerant. The valve body () consists of a body upper portion () and a body lower portion () narrower than the body upper portion (), and bolt fitting grooves () opening in the flank of the valve body (), preferably opening obliquely downward, are formed at the boundary () of the body upper portion () and the body lower portion (). With such a layout, the material required at the boundary () can be reduced furthermore and the quantity of material required for the valve body () can be reduced furthermore, as a result. Since the opening width (minimum spatial dimension) w is smaller than the diameter of bolt, a seating surface is assured sufficiently around the bolt fitting groove () and the bolt does not drop off from the bolt fitting groove ().

Expansion valve

An expansion valve includes a valve body having a valve body hole, a first passage, a bottomed valve chamber, a second passage, a third passage and a guide member disposed in the valve body hole between the first passage and the third passage. The valve body hole has a first valve body hole portion and a second valve body hole portion of different diameters forming a valve body step between the second passage and the first passage. The guide has a first guide portion and a second guide portion of different diameters forming a guide portion step. The guide is sized to be slidably received by the valve body hole in a close-fitting relationship with the first valve body hole portion receiving the first guide portion, the second valve body hole portion receiving the second guide portion and the valve body step and the guide portion step contacting each other.

An expansion valve has a solenoid relief valve equipped in an air conditioner for decompressing and expands a refrigerant and supplies the same to an evaporator. A high-pressure refrigerant from a compressor enters a valve chamber. The refrigerant traveling towards the evaporator flows through a first passage. The refrigerant returning from the evaporator toward the compressor flows through a second passage. A valve seat is disposed between the valve chamber and the first passage. A valve body has a refrigerant chamber disposed in parallel to the valve seat and communicates the valve chamber and the first passage. A valve device is capable of coming into contact with and separating from the valve seat. A power element drives the valve device. A solenoid relief valve is disposed between the refrigerant chamber and the first passage.

Expansion valve having solenoid relief valve

An expansion valve comprises a prism-shaped body , and a valve chamber is formed within the body . Refrigerant supplied from a compressor flows into the valve chamber through a passage , passes between a valve means and a valve seat , and travels toward an evaporator through a passage . Refrigerant returning from the evaporator enters the body through a passage , and after the refrigerant temperature information is transmitted to the operating shaft , the refrigerant flows out through a passage toward the compressor. Passages and open to a first side surface of the body, and passages and open to a second side surface orthogonal to the first surface. Such structure improves the degree of freedom for mounting the expansion valve

A thermal expansion valve has a valve chamber in a valve body , and controls the flow rate of refrigerant from a condenser and a receiver, and the refrigerant travels to an evaporator through a passage . Refrigerant returning from the evaporator transmits the temperature of refrigerant to a heat sensing shaft connecting to a power element portion while traveling through a passage . A cover has a head portion and a tapered portion , and is mounted to the top portion of the valve body . Tapered outer surfaces of the tapered portion of the cover and tapered surfaces of the valve body form approximately identical surfaces. A concave portion of the head portion covers the power element portion , and its peak portion forms a curved surface

Thermal expansion valve

The invention provides a thermal expansion valve for a car air conditioner, which prevents a hunting phenomenon. The thermal expansion valve is provided with a refrigerant passage from an evaporator toward a compressor formed in an inner portion thereof and a temperature sensing and pressure transmitting member having a heat sensing function and forming a hollow portion in an inner portion thereof, which is installed in the passage. In the thermal expansion valve, a distal end of the hollow portion of the temperature sensing and pressure transmitting member is fixed to a center opening portion of a diaphragm constituting a power element portion for driving the temperature sensing and pressure transmitting member, an upper pressure chamber within the power element portion formed by the diaphragm and the hollow portion are communicated with each other so as to form a sealed space having a working fluid charged therein, and a thermal-transfer delay means is provided between a heat ballast member received in the hollow portion and an inner wall of the hollow portion.
