Title: Zoom lens
Inventor: KONO TETSUO
IPC: G02B13/18
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To efficiently make the whole of an optical system unit compact by executing a variable power action by changing an air gap between a 1st group and a 2nd group and satisfying a specified condition. SOLUTION: This zoom lens is constituted of the 1st group Gr1 having negative power and the 2nd group Gr2 having positive power in turn from an object side. Then, the variable power action is executed by changing the air gap between the groups Gr1 and Gr2. Besides, it is constituted so as to satisfy the conditional expressions of 0.2<T1-2/Y'<0.8 and 0.1<|f1/f2|/Z<0.6. Provided that (T1-2) shows the air gap between the groups Gr1 and Gr2 at a telephoto end, Y' shows the maximum image height, f1 shows the focal distance of the group Gr1, f2 shows the focal distance of the group Gr2 and Z shows a zoom ratio. Thus, the constitution of a lens barrel is realized and the optical system unit can be made compact. Besides, the whole length of the optical system can be shortened while keeping optical performance.

Title: Motor machine tool
Inventor: SUZUKI TAKASHI
IPC: B23Q17/00
Filed: 1981-06-12
Abstract: PURPOSE:To decide the outer-diameter of a tool held in a drill chuck by producing a signal proportional to the outer-diameter of the tool held in a drill chuck while providing means for holding sail value. CONSTITUTION:The flexible gear 5 of a motor machine tool is geared with the casing gear section formed at the tool body side of a casing 4 coupled at the outside of the body 3, and each tooth is determined such that when the diameter of the drill 1 has varied to the maximum diameter the relative rotary displacement between the casing 4 and the gear 5 will be within 360 deg.. The casing matching mark 8 and the gear matching mark 9 are marked on the casing 4 and the gear 5 in order to decide the optically or magnetically detectable relative rotary displacement. Consequently the diameter of the drill 1 held in the drill chuck 1 can be decided from the shift between both marks 8, 9.

Filed: 1986-04-22
Abstract: PURPOSE:To make a select shock at the time of forward or backward selection preventable from occurring on the occasion of starting a forward-backward selector mechanism, by inserting a starting clutch into a power transmission system between a hydraulic power transmission device and an input cone disc. CONSTITUTION:At a neutral position of a manual valve, both forward and backward clutches 21 and 22 are released, and engine power is not transmitted to an output shaft 2, stopping a vehicle. Simultaneously, a starting clutch 18 is also released so that dragging torque by a hydraulic coupling 3 is interrupted, therefore it is in no case transmitted to cone discs 6-9 and cone rollers 16 and 17, keeping the rotation suspended intact during stoppage. And, at the time of starting these forward/backward clutches 21 and 22 and the starting clutch 18 are all engaged together, and cone discs 6-9 and cone rollers 16 and 17 are driven and coupled together, but at this time, since these cone discs 6-9 and cone rollers 16 and 17 are all stopped, thus no select shock occurs there.
