An object of the present invention is to make a housing for a ceiling-mounted type air conditioner small-sized without decreasing the performance and capacity of the air conditioner, and particularly to decrease the length of the housing in the depth direction, thereby facilitating the installation of the air conditioner and improving the room appearance. To achieve the above object, a heat exchanger is bent into a doglegged shape, the bent portion thereof is convex to the air inlet side, and the heat exchanger is inclined so as to be raised on the air inlet side. A cross flow fan rotating around a horizontal axis is disposed on the downstream side of the heat exchanger.

An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. A skip code is entered for portions of transaction data that is not pre-stored. An automatic transaction processing unit reads the transaction data stored in the card and receives from the customer any additional data which was not previously stored in the card (e.g. data associated with the skip code) and which is required to complete a transaction.

The present invention concerns a plumb-bob device for vertical pointing operation with a beam-casting housing supported vertically by a plurality of legs via a gyroscope mechanism. The device has a reduced size, so that it can be handled quickly and conveniently on a construction cite. The legs are mounted for expansion and contraction in and around an upper end portion via the gyroscope mechanism on and around an upper end portion of the housing. The legs each have an inner surface complementary to the outer periphery of the housing. The device thus can assume a shape just like a long pencil when the legs are contracted. For vertical pointing operation, the housing is held vertically by the legs in an expanded state. The device can be used as an inverted plumb-bob device and also as a pointer by mounting a retaining member, which has a string, on lower end portions of the legs in the contracted state thereof.

An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. An automatic transaction processing unit reads the transaction data stored in the card, checks to determine what transaction data, if any, which is required for the processing of the transaction is not stored in the card and, if necessary, receives from the customer any additional data which was not previously stored in the card and which is required to complete a transaction.
摘要:
A casing includes half members coupled with each other. The half members in cooperation define an inner space for containing a storage device. A removable storage device unit is thus established. A guide surface is defined on the casing. The guide surface is related to a predetermined guide located on an enclosure defining an interior space for containing the casing. The guide surface serves to guide movement of the casing with respect to the enclosure. The removable storage device unit can easily be detached from the enclosure without disassembling the enclosure. The removable storage device unit can easily be carried. The user is allowed to utilize the single storage device common to a plurality of or various electronic apparatuses, for example. This enables a facilitated exchange of data between the electronic apparatuses.

A storage device unit includes a storage device containing a recording medium in a housing. A heat radiation device is attached to the storage device outside the housing. The storage device unit enables prevention of rise in the temperature of the storage device based on the action of the heat radiation device. The storage device keeps normally operating in a high temperature condition. Moreover, the heat radiation device can be attached to a conventional storage device, so that it is possible to avoid the redesign of the storage device. The storage device having a resistance to high temperature can be provided in this manner at a lower cost.

An enclosure of an information processing apparatus is designed to enclose a processor. An opening is defined in the enclosure. The opening is designed to guide insertion and removal of a storage device. The user is allowed to easily attach and detach the storage device such as a hard disk drive to and from the enclosure. The user may simply own a single storage device for plural enclosures. Various information related to the operating conditions is stored in the storage device. If the user is allowed to operate the information processing apparatuses solely based on the single storage device, the accustomed operating conditions can always be established for plural information processing apparatuses.
摘要:
A voice recording card (1) can record and reproduce a message and when it is inserted into a transmitting and receiving apparatus (3), it can transmit and receive the message. In a recording mode, the message is applied through a microphone (14), converted into a digital signal by an analog/digital converter (21) and is recorded in a memory (22). In a transmission mode, the content of the message is read out from the memory (22) and is transmitted through an interface (24) to the transmitting and receiving apparatus (3). In a receiving mode, the content of the message received by the transmitting and receiving apparatus (3) is recorded in the memory (22) through the interface (24) and is read out, in a reproduction mode, from the memory (22) and converted into an analog signal by a digital-analog converter (23) to be outputted from a speaker (15). The card (1) comprises a central processing unit which controls an electric structure of the card (1) in response to the mode designated by a mode designation key included in a keyboard (13).
