An air conditioning system comprising an outdoor and an indoor unit connected through common power supply lines. The outdoor unit including a first communication circuit using one of the plurality of common power supply lines and one signal line independent of the power supply lines. The indoor unit comprising terminals connected to the first communication circuit; a switch configured to set the first and second communication circuits to a connection state or a disconnection state; a detection circuit configured to detect a voltage between the terminals; and a controller configured to control the switch. The switch sets the first and second communication circuits to the disconnection state when the voltage detected by the detection circuit equals or exceeds a predetermined threshold value; otherwise the switch sets the first and second communication circuits to the connection state.

An epoxy resin composition is a one-part epoxy resin composition for hermetic sealing of an electronic component or an electrical component, containing: a liquid epoxy resin; dicyandiamide; and a filler, the filler having an average particle size between 0.1 μm and 1 μm, the filler containing particles not less than 5 μm in particle size in an amount of not more than 20 wt %, and the amount of the filler contained in the one-part epoxy resin composition being between 5 and 60 parts by weight relative to 100 parts by weight of the liquid epoxy resin. This achieves a one-part liquid epoxy resin composition in which a great variety of curing agents can be used and dissociation of an epoxy resin and a curing agent is suppressed even when used in a gap of approximately several tens of micrometers.

The process of the present invention for producing a metal film includes: forming an organic film using a primer composition containing an addition polymerizable compound including three or more reactive groups, an acid group-including addition polymerizable compound, and a hydrophilic functional group-including addition polymerizable compound; forming a metal (M1) salt from the acid group; substituting the metal (M1) salt of the acid group with a metal (M2) salt by processing the organic film with a metal (M2) ion aqueous solution containing a metal (M2) ion having less ionization tendency than the metal (M1) ion; reducing the metal (M2) ion so that a metal film is formed on a surface of the organic film; and oxidizing the metal film. This provides (i) a process for producing a metal film and a metal pattern, at low cost, on an arbitrary substrate, (ii) a metal film, and (iii) use of the meta film.

摘要:
Provided is a method for bonding glass members for optical communication, which can achieve sufficient bonding strength and resistance to separation between the glass member and the adhesive layer. The method is characterized by vaporizing a silane-coupling agent by heating, treating glass members for optical communication with the silane-coupling agent vapor, and bonding the glass members to each other with an adhesive.

In a communication control system for an air conditioner including an outdoor unit, plural indoor units and control equipment such as a remote controller, etc. which is connected to each indoor unit through a communication line, data communication being carried out between each indoor unit and the control equipment through the communication line, each indoor unit is equipped with a communication control device having a power source circuit 59 to which a power source voltage is supplied from a main power source, a communication superposing circuit for superposing communication data on the power source voltage, a transistor 54 for ON/OFF-controlling the supply of the power source voltage from the main power source to the communication superposing circuit, and a polarity coincidence circuit 63A that passes the output of the communication superposing circuit therethrough to the communication line and depolarizes the power source voltage from the external. Even when an indoor unit functioning as a power supply source cannot supply power due to some trouble, another indoor unit is automatically selected as a power supply source so that the power supply operation can be continuously carried out in the air conditioner.
摘要:
In a machine tool provided with a column 4 mounted on a back end portion of a bed 1 having a table 2, and a spindle head 20 arranged in a vertically movable manner to the column 4, both sides of an upper portion of the column 4 is connected with both sides of a front-end portion of the bed 1 through support members 42, 43. Even the machine has a structure that the spindle head 20 embeds a main shaft rotating at high rpm, vibration can be reduced. The column is affected by a force to fall down in the direction due to the weight of the spindle head 20, but the tilt caused by the force can be avoided. Accordingly, a high finish surface accuracy can be ensured without an increase in size and weight.
