Title: Asynchronous positive clutch structure
Inventor: ARAN RICHIYAADO DEEBISU
IPC: F16D21/04
Filed: 1994-02-16
Abstract: PURPOSE: To obtain a smooth, nearly synchronized clutch connection without increasing the risk of erroneous shifting by increasing the number of interengageable clutch teeth provided in respective clutch members to be more than that of clutch teeth normally used in similar nonsynchronized positive clutch members. CONSTITUTION: Backlash of the device is the sum of backlash due to spline connection between a clutch collar 50 and a main shaft 46, and backlash among the clutch collar, interengageable clutch teeth 208, 210 of respective gears. The number of clutch teeth 208, 210 is determined as a function of pitch radius 214 and backlash 216 when these are taken into consideration for durability. Based on these considerations, maximum number of clutch teeth or allowable, practically maximum number of clutch teeth is determined. If the number of clutch teeth defined as N, P is the number over 10, the pitch diameter is PD in inches, the number of clutch teeth has a relationship represented by N>=P.PD.

Title: Measuring device
Inventor: MORI AKIRA
IPC: G01C19/5649
Filed: 1995-03-01
Abstract: PURPOSE: To provide a small measuring device which can be installed on the body and is small and can be installed without troublesomeness and can easily and inexpensively measure arm swinging speed and a twist of an arm or the like. CONSTITUTION: The measuring device containing a vibrating gyro 10, a converting means and a display means is incorporated into a wristwatch. When a person having this wristwatch starts action, turning angular velocity detected by the vibrating gyro 10 is converted into data such as arm swinging speed by a converting means, and is displayed on a data display window of the wristwatch. Since this is very small, when it is installed on the body, desired data can be easily and inexpensively known. When it is incorporated into a comparatively small accessory such as a wristwatch, a highly value-added accessory can be realized.
