Abstract: A method for superimposing an image of an optoelectric component on a substrate with the use of a single camera. Specifically, the camera looks through a transparent alignment tool that is holding the component, to the substrate below it, thus allowing both the component and the substrate to be seen together by the camera. The alignment tool and substrate are adjusted to precisely align the two and then are brought together while being seen by the camera. On laser chips, the chip is energized while on the glass alignment tool to produce a laser spot that is superimposed on the visible light image via a series of lenses and mirrors.

Abstract: In a dicing step in which a spout face is formed and a flow path length is defined, for example, a region in a cut depth direction is divided into a cutting region B containing spouts, a region A above the region B, and a region C below the region B. Feedrate v2 when the region B is cut is applied for cutting head material with high quality. Feedrate v1 when the region A is cut is set to, for example, three times the feedrate v2 when the region B is cut, and the blade form is shaped at the feedrate v2. Feedrate v3 when the region C is cut is the same as the feedrate v2 when the region B is cut, whereby affecting the upper cut face is prevented and the yield is improved.

Abstract: A far infrared radiation heater 33 is disposed on the back of a ceiling of a drying chamber 11. The inside of the drying chamber 11 is evenly heated by the heat emitted from the far infrared radiation heater 33. The drying chamber 11 is provided with air charge means 16 and air exhaust means 17 each communicating with the inside thereof. Outside air is introduced into the drying chamber 11 by means of the air charge means 16. On the other hand, the air exhaust means 17 continuously maintains the inside of the drying chamber 11 in a state of reduced pressure. Thus, objects to be dried which are placed in the drying chamber are dried by heating under reduced pressure while continuously introducing fresh air. Therefore, the present invention provides a system for drying objects to be dried whereby not only can dried products be produced within a short period of time but also the flavor is satisfactorily retained in the dried products.

Abstract: An excavating bucket for rotating bucket excavators has a trough-shaped bucket having a forward edge formed by a U-shaped bucket lip. The lip has multiple shank holes and a cutting tooth in each shank hole which is removably attached to the lip. There are two sets of corner shank holes which lie on a circular line and receive a corresponding number of corner cutting teeth. Cutting portions of the corner teeth can be variously shaped so that the corner teeth can be adapted for varying cutting conditions. The cutting teeth have a weakening undercut adjacent their respective shafts so that forces acting on the teeth cause tooth deflections in the area of the recess while a remainder of the tooth, to which wear resistant layers of materials can be applied, is subjected to substantially no deflection to prevent a spalling of the wear resistant layers. An aft end of the bucket is defined by a multiplicity of side-by-side chains mounted on bars extending transversely between side plates of the bucket.
