Title: Damper device
Inventor: OYAMA MAKOTO
IPC: F16F9/50
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a damper device which changes an operating characteristic of a movable unit in accordance with a load acting in the damper device and generates a small characteristic change even in the case of changing a temperature. SOLUTION: This device is constituted by a casing 10, movable unit 11 arranged in the casing 10, operating fluid 13 sealed in the casing 10, and an orifice hole 16 allowing the operating fluid 13 to flow according to movement of the movable unit 11. An area of the orifice hole 16 is changed in accordance with force applied to the movable unit 11, and a change rate of the area is changed so as to suppress changing of a damper characteristic due to temperature dependence of physical properties of the operating fluid 13. In the case of increasing viscosity of the operating fluid 13 according to a change of temperature while a sectional area of the orifice hole 16 is changed in accordance with force acting in a damper, changing of the damper characteristic can be suppressed by decreasing the change rate of the sectional area of the orifice hole 16.

Title: Network device
Inventor: MATSUO MASAHIRO
IPC: H04N5/00
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a network device which improves the security of personal information when service provided through a connected network is available. SOLUTION: A remote controller 2 when indicating an access destination to a main device 1 sends its machine identification code. The main device 1 once receiving the indication for access from the remote controller 2 adds the identification code of the remote controller 2 to information obtained by accessing the access destination and outputs them. The remote controller 2 displays only the output given its machine identification code at a reception display part 25. The information that the main device 1 has acquired from the network 7 can, therefore, be confirmed at the display part 25 of the remote controller 2 and the danger that circumferential persons see the information can be suppressed. The security of the personal information is therefore improved.
