Title: Electronic key device for vehicle
Inventor: YAMAMOTO KEIJI
IPC: E05B83/00
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To control the start of an engine by the electronic keys of various shapes, by mounting an insertion port into which the electronic key can be inserted, and rotating a rotary switch by the electronic key inserted into the key insertion port. SOLUTION: In a rotary switch 24 where an electronic key 60 is inserted and operated, an operation knob 40 is formed in such manner that it is projected to a front face of the rotary switch 24, and a slit-shaped key insertion port 44 is formed. The operation knob 40 is made rotatable in a condition that a rectangular elecronic key 60 is inserted into the key insertion port 44, and the operation knob can be directly rotated by a hand. By applying this structure, the operation itself can be smoothly performed even when a driver possesses the electronic key which is not agreed with the shape of the key insertion port 44. That is, the electronic keys of various shapes can be applied as the electronic key 60, and it is unnecessary to change the shape of the key insertion port 44 corresponding to the shape of the electronic key 60.

Title: Bellows
Inventor: TAKEUCHI KUNIO
IPC: F16D3/84
Filed: 1984-10-31
Abstract: PURPOSE:To allow a smooth movement in the axial and radial directions by continuously changing the angle of crest and the bottom land diameter of the corrugated section, and dispensing with changing the thickness or the pitch of the corrugated section. CONSTITUTION:The angle of crest 21 is made increasingly smaller gradually from one end 11 toward the other end 12, while the diameter of the bottom land 22 is made increasingly larger. When the bellows so arranged contracts under its free state, the contraction starts at the other end 12 to ultimately reach the end 11, and when it expands under the contracted condition, the expansion starts at the end 11 to reach the other end 12. Such is the characteristics of the instant bellows. Therefore, there is no need to change the thickness or pitch of the corrugated section, and the change in the axial and radial directions becomes smooth.
