Publication number: 20160281812Abstract: The new springs provide many different levels of accelerate increasing physical force. There are two rules to help you form a new spring. The deflection between two adjacent wire rings always has to be kept linear along the whole spring. First, along the whole spring wire, the (cross section area)?2 should be linear. Second, along the whole wire, the pitch could adapt linear change. To get different accelerate effects, you need to adjust these constants in the two linear functions of the two rules. The new springs are flexible enough to fit in many places, i.e. in factory lines, in robot end effector, in artificial legs, in giant machines . . . etc.Type: ApplicationFiled: February 25, 2014Publication date: September 29, 2016Inventor: Christina Xiaolin DAI

Publication number: 20160281815Abstract: Shock absorber including a suction passage allowing flow only from a reservoir towards a pressure side chamber, a rectifying passage allowing flow only from the pressure side chamber towards an expansion side chamber, and a damping force variable valve allowing flow only from the expansion side chamber towards the reservoir. A large pressure-side pressure chamber communicating with the pressure side chamber, and an outer peripheral expansion-side pressure chamber communicating with the expansion side chamber sandwich a free piston slidably moving within a bottom housing forming a pressure chamber. Because a pressure-side pressure-receiving area of the free piston is larger than an expansion-side pressure-receiving area in a contraction operation in which a piston moves downward, the free piston can move downward even in a uniflow-type shock absorber in which pressure in the expansion side and pressure side chambers become equal whereby damping force can be reduced during an input of high-frequency vibration.Type: ApplicationFiled: March 20, 2014Publication date: September 29, 2016Applicant: KAYABA INDUSTRY CO., LTD.Inventors: Takashi TERAOKA, Tatsuya MASAMURA
