  • Publication number: 20030017873
    Abstract: Three user characters are displayed in a chat room. When a user inputs a character string, the character string is displayed on the screens of the respective users. When a character string inputted by a user contains a character string “Ha,Ha,Ha”, a data table outputs an event corresponding to the character string “Ha,Ha,Ha”. All the user characters participating in the chat make a laughing action, uttering the laughing sound “Ha,Ha,Ha”. The input character processing method not only can simply transmits utterances of respective participants but also can occur various events.

  • Publication number: 20020194016
    Abstract: A driving support system is provided for guiding a vehicle safely to the desired destination. To this end, use is made of a database of the past traffic accidents owned by an insurance company or public institution. Based on the comparison between the GPS data about the current position of the vehicle and the site data of the past accidents recorded in the database, the driver can be notified, by a warning beep or warning message on the monitor of the navigation system, that his or her vehicle is approaching the site of the past accident on the route. In this manner, though a past accident is now invisible, the driver can be careful in passing by the site where the accident occurred.

  • Patent number: 6494059
    Abstract: A receiver-tank is provided with a vertical tank main body 140. An inlet 131 and an outlet 132 are provided in an inlet-and-outlet forming member 150 as a bottom wall of the tank main body 140. A desiccant-filled-layer 135 as a flow-resistance layer is provided in a lower part of the tank main body 140, and an upper space is formed above the desiccant-filled-layer 135. A suction pipe 133 is provided in the tank main body 140 with the lower end connected with the outlet 132 and the upper end opened toward the upper space. When the refrigerant introduced into the tank main body 140 from the inlet port 131 goes up through the desiccant-filled-layer 135, the flow velocity decreases, and liquid-stagnation R is quietly created bin the upper space. The liquefied refrigerant of this liquid-stagnation R flows out of the outlet 132 through the suction pipe 133. Thereby, the stable liquid refrigerant can be supplied.

  • Patent number: 6484547
    Abstract: In the present invention, a thin and disc-shaped blank made of steel plate is used. The present invention provides a method of manufacturing a sheet metal member comprising a circular base plate, and an annular projection bulged from at least one surface of the base plate so as to be concentric therewith, which can be easily and cheaply produced without loss of material, by only a few steps. A blank having an outer peripheral portion which has been thickened by a former step, is rotated while it is held between an upper and lower dies. At the same time, an edge angle portion of an outer peripheral surface of a drawing roller is pressed against one surface of the thickened outer peripheral portion which extrudes outwardly from the upper die of the blank, and the drawing roller is rotated, while it is moved in the direction of the center of the blank, and the thickened outer peripheral portion is drawn so as to make it think, thereby bulging the annular projection axially.

  • Publication number: 20020148248
    Abstract: This refrigeration system is an orifice-tube system constituting a refrigeration cycle in which a refrigerant passes through a compressor 1, a condenser 10, an orifice-tube 3, an evaporator 4, and an accumulator 5 in this order and then returns to the compressor 1. The condenser 10 is constituted by the so-called multi-flow type heat exchanger having a plurality of passes P1-P3. The intermediate pass P2 is constituted as a decompression pass for decompressing the refrigerant. After condensing the refrigerant by the first pass P1, the condensed refrigerant is decompressed and evaporated by the decompression pass P2, and then the evaporated refrigerant is re-condensed by the third pass P3. This refrigeration system is excellent in response characteristic to thermal load fluctuations and in refrigeration performance.
