Title: Lens barrel for zoom lens
Inventor: UESUGI KIYOUZOU
IPC: G03B5/00
Filed: 1978-12-18
Abstract: PURPOSE: To smooth the movement of moving lens groups for zoom, by slidably fitting the supporting frame of moving lens group for zoom to the inner and outer sides of a stationary lens barrel.  
     CONSTITUTION: A supporting sleeve 4 is slidably fitted to the outside of a stationary lens barrel 1 mounted on a camera, and the arm thereof is projected into the stationary lens barrel 1 through a cam groove 12 which penetrates through the stationary lens barrel 1, thereby securing a first moving lens group for zoom Z 1 . At the same time, a supporting ring 9 to which is secured a second moving lens group for zoom Z 2  is slidably fitted to the inside of the stationary lens barrel 1. In this setting, when an operating ring 3 is moved back and forth, the supporting sleeve 4 rotates along the cam groove 12 through balls 5, and the supporting ring 9 also turns along the cam groove 14 through the engagement of the cam groove 13 and pin 10. Thus, without risk of collision of the supporting sleeve 4 and the supporting ring 9, the variable power may be possible in a wide range.

Title: Wire bonding apparatus
Inventor: IMAIZUMI TATSUO
IPC: H01L21/60
Filed: 1978-12-19
Abstract: PURPOSE: To reduce the used wire amount in a wire bonding apparatus and stabilize the wire bonding by setting the height of a capillary when the capillary is moved above the stitch bonding position different from the height thereof at its tail cutting position.  
     CONSTITUTION: The height of a capillary 2 is increased at its top dead point a 2  to thereby reduce the inclined angle θ 2  of a gold wire 6 with respect to the vertical  line when the capillary 2 is horizontally moved to its stitch bonding position. Thus,  the gold wire 6 does not bend directly above a gold ball or directly below the capillary 2 to thus readily increase the height of its loop. The height of the capillary 2  becomes a 3 <a 2  at its tail cutting position, and the gold wire is cut directly below  the capillary 2. When the gold ball is yet in molten state after the gold wire is cut,  the gold wire 6 is not rocked by the curled return thereof or by the wind pressure  of a torch to cause no strain of the ball. Thus, the length of the tail of the wire is  shortened to thereby reduce the used amount of the gold wire 6.

Title: Melting treatment method for waste
Inventor: FUJIMOTO TADAO
IPC: B09B3/00
Filed: 1981-10-05
Abstract: PURPOSE:To change melted slag formed by incinerating and melting the waste to be treated into crystalline structure having strong strength, and to utilize the slag sufficiently as aggregate, also by mixing heat-generating flux into the melted slag and slowly cooling the melted slag. CONSTITUTION:The heat-generating flux 5 is mixed into the melted slag D shaped through incineration and melting in the melting furnace of an incineration melting process 3 in a slow cooling process 4. The heat-generating flux 5 mixed into the melted slag D is burnt and generates heat by the heat of the melted slag D, and the slag is heated through the heat generation while the flux after heat generation floats on the surface of the slag by the difference of specific gravity, forms a heat insulating layer and limits the radiation of the slag, thus slowly cooling the melted slag D. Consequently, the melted slag D is slowly cooled. Accordingly, crystals grow sufficiently during the time when the melted slag D is slowly cooled in the slow cooling process 4, and the slag is recovered as slag E in crystalline structure having strong strength.
