Title: Damping force generating structure of hydraulic buffer
Inventor: UDA KOICHI
IPC: F16F9/32
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To generate upper zone damping force higher than a normal zone of stroke by fixing an auxiliary seal to an inner surface of a cylinder, and discharging a flow quantity which raising speed is multiplied by a pressure receiving area of a bush to an upper chamber since the bush is connected to a piston rod, and generating auxiliary damping force. SOLUTION: In association with raising of a piston rod 100, a bush 102 is entered to an upper zone Su of stroke, and communication between an upper chamber A and an auxiliary chamber E is shut out when the bush 102 is fitted to an inner circumferential lip 101A of an auxiliary seal 101. When the piston rod 100 is further raised, operating oil having a flow quantity which piston speed is multiplied by a pressure receiving area of the bush 102 is discharged from the auxiliary chamber E to the upper chamber A since the bush 102 is connected to the piston rod 100, and auxiliary damping force is generated by a passage resistance. In an upper zone of stroke, auxiliary damping force is applied to normal expanding side damping force, and upper zone damping force which is larger than the normal zone of stroke is generated.

IPC: H02P21/22
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To surely detect a speed detection abnormality whether it is in a high-speed range or in a low speed range. SOLUTION: To vector-control an induction motor 2 a speed detection value ωr is calculated with a pulse signal P of a speed detection sensor (a pulse pickup).

Title: Diffused light emitting device
Inventor: SAKAI MASAHISA
IPC: G02B5/02
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To improve productivity, heat radiating property, convenience of use and so on. SOLUTION: Plural LEDs(light emitting diodes) 14 are directly attached to the lower surface of a fixing plate 11. The productivity and the positioning accuracy are improved because thereby conventional fixing of the LEDs with lead wires and fixing members are not necessary any more. Also the fixing plate 11 radiates the heat generated by the LEDs 14. However, as the direct attachment of the respective LEDs 14 to the lower surface of the fixing plate 11 like this results in the directional angle of the optical signal turning out to be limited within a vertically downward narrow range, a diffusion lens 12 diffusing the optical signal with specified light distribution is arranged so as to ensure a wide directional angle for the transmission range of the optical signal and to obtain nearly uniform intensity of the optical signal within a specified range.
