Abstract: An electric compressor includes a compression mechanism that compresses refrigerant, an electric motor that drives the compression mechanism, a drive circuit that drives the electric motor, a housing that forms therein a motor chamber in which the electric motor is accommodated, a cover that is attached to the housing, a rotary shaft, and a relay terminal portion. The cover is configured to cooperate with the housing to form a drive circuit chamber in which the drive circuit is accommodated. Rotation of the electric motor is transmitted to the compression mechanism through the rotary shaft. The relay terminal portion provides electrical connection between a wire of the drive circuit and a wire of the electric motor. The housing includes a partition wall that separates the motor chamber and the drive circuit chamber from each other. The relay terminal portion is disposed between the partition wall and the rotary shaft.

Abstract: An electric compressor includes a compression portion, an electric motor, a drive circuit, a housing having a cylindrical shape and accommodating the compression portion and the electric motor, a cover attached to the housing and cooperating with the housing to accommodate the drive circuit, and a protector. The protector is configured to protect the cover from an external force. The protector includes a fixing portion that is fixed to the housing and a protection portion that is formed in a plate-like shape. The protection portion is disposed to face and to be spaced from the cover. The protector extends in a diametrical direction of the housing. A plurality of recesses is formed in the protection portion toward the cover such that the protection portion projects toward the cover. The recesses extend in an extending direction of the protector.

Abstract: While a base model has been determined for a product, in a system for performing a configuration designing operation of the product by setting a specification value to a specification item of the product, a product configuration design aiding system aids that a configuration designer can easily perform the configuration designing operation while following a restriction condition of a specification value of a specification item. A specification configuration information database is constructed which describes restriction conditions available for the specification values with respect to the specification item, and a configuration designing screen for inputting the specification values with respect to the specification item is displayed so as to conduct an input by the configuration designer.

Abstract: A specification plan of an order-made product suitable for a building structure plan is generated promptly. A WWW server 11 and a database server 12 are provided to the equipment designer's side. The database server 12 has a drawing database 9 that registers a CAD symbol for each product. A CAD symbol for each product includes: effective space information, which expresses a space to be secured for installation of the product; product name information expressing a name of the product; structure information expressing structural features (size, shape, etc.); product specification information; option data; etc. On the other hand, WWW server 11 has a symbol generation data interface 3, through which requirements specification data for an order-made product can be received from a WWW client terminal 2, and a CAD symbol of the order-made product can be taken out from the side of the WWW client terminal.

Abstract: A renewal proposal support system that performs communication with a sales terminal device includes a configuration information storage unit for storing information on components of a product provided for a customer, a component information storage unit for storing the components, a configuration rule storage unit for storing information on advisability of combination between the components, and a control unit for performing processing on a change of one of the components. The control means refers to the configuration information storage unit, thereby displaying the components on the sales terminal device, and notifies an operator of the sales terminal device of other component that cannot be combined with the one of the components targeted for the change, upon receipt of a command for the change of the one of the components from the sales terminal device.

Abstract: A fluid machine includes a motor and a motor housing. The motor housing defines a motor chamber for accommodating the motor. The motor chamber is filled with inert gas. A rotor rotates in accordance with rotation of the motor. A pump housing defines a pump chamber for accommodating the rotor. A dividing wall is located between the pump housing and the motor housing. The pump housing and the motor housing are attached to each other via the dividing wall. Therefore, water is prevented from being generated in the motor chamber even if fluid that contains hydrogen leaks from the pump chamber to the motor chamber.

Abstract: In a design aiding method, a design aiding apparatus having the method, or a design aiding system possessing a plurality of such design aiding apparatuses for use in a field of computer software to facilitate a design process, there is determined, for a product having many variations of attributes and values thereof, an appropriate design procedure according to a state of design in a process of determining the attribute values of the product satisfying a request of a client. At occurrence of, for example, conflict during the design, the design procedure is guided for the user to obtain a design plan conforming to the request.
