Abstract: An underground structure cover comprises a cover body (10) and a receiving frame (20) arranged so that the cover body is fitted in and supported by the receiving frame in the manner that an inclined surface (11) of the outer circumference of the body meets an inclined surface (21) of the inner circumference of the frame. The inclined surfaces (11, 21) each have an upper inclined surface (11a, 21a) and a lower inclined surface (11b, 21b), and the lower inclined surfaces (11b, 21b) are steeper than the upper inclined surfaces (11a, 21a). The body (10) is fitted in and supported by the part (20) at the upper inclined surfaces (11a, 21a) and the lower inclined surfaces (11b, 21b). By this, the body is prevented from being wedged into the frame too deeply and also from becoming inclined with respect to the frame or riding up.

Abstract: When a remote device returns an address in response to a search signal, a control unit searches a phone book memory based on this address, reads the user name of the corresponding remote device, and displays it on a display unit. On the other hand, when the phone book memory does not store the user name of the corresponding remote device, the control unit receives the device name from the remote device, and displays it on the display unit. When the control unit cannot receive this device name, the control unit displays the address on the display unit.

Abstract: A character input apparatus includes a key-in unit configured to input a character by a keystroke, a writing input unit to input a character by writing, a storage to store character strings, and a control unit to control the storage to store, in the storage, a first character input by the key-in unit and a second character input by the writing input unit in a form of a single character string including the first character and the second character.

Abstract: A cover assembly includes a support frame (20) fixed to a utility access hole and a rounded cover (10) fitted into the support frame. The support frame is provided in its upper portion with an S-curved inner peripheral surface (20b) having a convex curved surface portion (21) and a concave curved surface portion (22) that continues to the convex curved surface portion and is formed thereabove. The cover has an S-curved peripheral surface (10b) that is substantially complementary in shape to the S-curved inner peripheral surface of the support frame. When the access hole is closed by the cover, the cover is smoothly fitted into the support frame due to a guide function of the S-curved inner peripheral surface of the support frame.

Abstract: An air conditioner equipped with a solar generator is disclosed. The solar generator is capable of converting the DC power generated by a solar cell into the AC power whose voltage and frequency correspond to that of the commercial power source. The electrical power generated by the solar cell and the electrical power consumed by the air conditioner are monitored and may be displayed. The DC power generated by the solar cell is used directly by the air conditioner or used indirectly as the commercial power source by merging the converted AC power to the commercial power source. Further, the converted AC power may be selectively merged to the commercial power source depending on the various states of the air conditioner, and the air conditioning operations may be regulated depending on the electrical power generated by the solar cell.

Abstract: A DC power supply bus is used to connect a solar cell to an outdoor unit of air conditioners. The output voltage of each outdoor unit is controlled so as to maximize the power generation efficiency of the solar cell and the DC power supplied to the air conditioner is regulated to a predetermined value.
