A refrigeration cycle device for a vehicle includes a refrigerant circuit, in which a zeotropic refrigerant mixture is circulated, including a utilization heat exchanger including a first heat exchange portion and a second heat exchange portion disposed in series with the first heat exchange portion in a direction in which the zeotropic refrigerant mixture flows in the refrigerant circuit. The first heat exchange portion is disposed on an upstream side of the second heat exchange portion in a direction in which the zeotropic refrigerant mixture flows when the utilization heat exchanger functions as an evaporator of the zeotropic refrigerant mixture.

Refrigeration cycle device for vehicle

A glass panel (P) including a pair of glass sheets ( A), ( B) disposed in a spaced relationship with each other with forming a gap (V) therebetween, characterized in that peripheral edges of the glass sheets ( A), ( B) are bonded directly by a single metal material ( ) for sealing the gap (V) hermetically.

Method of manufacturing glass panel and glasspanel manufactured by the method

In order to provide a glass panel in which any substance which may be present on the glass surface and may then become detached to invite deterioration in the vacuum degree has been sufficiently reduced and which can maintain highly sealed condition against the surround atmosphere for an extended period of time, in a glass panel comprising a pair of glass sheet disposed in an opposing and spaced relationship with each other with a gap formed therebetween, the gap being air-tightly sealed by joining peripheral edges of the glass sheets with a sealing material, at least one of the glass sheets has a water contact angle of 30 degrees or less on a gap-side glass surface thereof.

Glass panel and its manufacturing method

Glass panel and production method therefor

To maintain high bonding performance between two glass sheets by metal material, thereby to obtain high gas tightness and bonding strength. A glass panel includes a pair of glass sheets ( A, B) disposed in opposition to each other with forming a gap (V) therebetween, the peripheral edges of the opposed glass sheets ( A, B) being directly bonded to each other by metal material ( ); wherein bonding faces ( Aa) in the opposed surfaces of the glass sheets ( A, B) to be bonded to the metal material ( ) are worked so as to obtain an average surface roughness below 30 nm.

Glass panel

A method of bonding respective objects made of different kinds of material to each other is disclosed. The method includes the steps of (A) contacting a bonding material in the fluid state thereof with respective bonding faces of the respective objects to be bonded, (B) mechanically abrading portions of the respective bonding faces contacting the bonding material to be bonded to each other, (C) setting the respective objects fixed in a predetermined position relative to each other while maintaining the respective objects in contact with the bonding material in the fluid state thereof, and (D) solidifying the bonding material to bond the respective objects to each other. In the respective steps (A)-(D), the bonding material is present at the bonding portions to be bonded to each other of the respective objects constantly and without discontinuities.

Method of manufacturing bonded assembly

A lead-free solder alloy substantially contains Sn and Ti, and has a temperature of a liquidus line of not greater than 400&deg; C. The lead-free solder alloy contains no toxic lead and has sufficient bonding strength to oxide materials such as glass and ceramics.
