Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To form uniform beads by preventing the flow of the molten metal of a fusion pool caused in the case of moving a welding torch from a flat surface to a curved surface part. SOLUTION: In the case of continuously welding a rectangular column 1 having the flat surface part 1a and an arc like corner part 1b, the welding torch 4 is moved to the flat surface part terminal M2 along the flat surface part 1a to weld the flat surface part 1a, the welding torch 4 is successively moved from the flat surface part terminal part M2 along the corner part 1b to weld the range of the stationary curved surface welding angle of 5 deg.-40 deg. from the flat surface part terminal M2 to a stationary curved surface welding terminal M3, then the column 1 is rotated by 90 deg. around the column axial center O. The welding torch 4 is simultaneously moved corresponding to the movement of the welding point in the corner part 1b during the rotation of the weld up to the terminal M4 of the corner part 1b.  The flow of the molten metal is prevented by waiting for the solidification of the fusion pool.

Title: Color separation optical unit
Inventor: YOSHIKAWA TOMOHISA
IPC: G02B7/00
Filed: 1990-09-25
Abstract: PURPOSE:To realize an optical unit which accurately holds the mutual positional relation between a solid-state image pickup element and a color separation prism by sticking and fixing the solid-state image pickup element and the color separation prism by using a columnar glass piece. CONSTITUTION:The solid-state image pickup element 1 and the color separation prism 2 are stuck and fixed by adhesive 4 in a state where the columnar glass piece is taken as a fixing member. Even when the element 1 is not parallel with the color separation prism, the element 1 contacts with the glass piece 3 at point because the fixing member 3 is columnar, and the quantity of the adhesive 4 becomes uniform all over the adhesive area and positional deviation caused by the hardening and contraction of the adhesive 4 is prevented. Thus, the positional deviation at the time of fixing the unit is restrained regardless of the degree of parallelism between the light receiving surface of the solid-state image pickup element and the light existing surface of the color separation prism.

Title: Construction equipment
Inventor: MURAHASHI TAKAYOSHI
IPC: E02F9/00
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the loosening of an open-close cover while improving appearance by preventing the deformation of the open-close cover. SOLUTION: The construction equipment is constituted in such a manner that an elastic holding mechanism 18 comprising a stopper 20, a grommet 22, etc., is installed at a place near to the upper side of an open-close cover 12 separated from a locking mechanism 16 and the stopper 20 is fitted elastically to the grommet 22 mounted on the housing box 10 side when the open-close cover 12 is closed. Accordingly, when the open-close cover 12 is closed, the looseness of the open-close cover 12 can be prevented by fitting the stopper 20 and the grommet 22. Since only the open-close cover 12 is held elastically by fitting the stopper 20 and the grommet 22, not only the open-close cover 12 can be closed easily but also the deformation of the open-close cover 12 is prevented, thus improving appearance.

IPC: H01L21/60
Filed: 1986-10-29
Abstract: PURPOSE:To ensure firm bonding by forming a recessed part in the surface of a film-carrier lead facing an electrode part of a semiconductor chip. CONSTITUTION:A recessed part 8 is formed in a belt-like long flexible insulating-film 3 or in the surface facing an electrode part for a device at two or more carrier leads 6 which are formed by being extended from the flexible insulating-film 3 to an opening 2 for the device. When the recessed part 8 and the leads 6 are formed, alkali-soluble resist is applied in the opening 2 for the device in order to prevent a copper layer on the reverse side from being etched through the opening 2 for the device. After the leads have been formed, the resist is exfoliated. By this method, the recessed part 8 prevents the lead from slipping when the electrode of a semiconductor chip and the film-carrier leads undergo thermocompression bonding, and reliable bonding can be executed.
