Patent DE-4230330-A1 (DE)
Title: Tape carrier package for soldering multipin chip to substrate by hf heating - comprises base film with device hose, leads having lead sections extending outwardly for bonding to substrate and lead sections extending into device hole
Inventor: AOMORI KOKICHI
IPC: H01L23/495
Filed: 1992-09-10
Abstract: The tape carrier package has a base film with a device hole and, on one side of the base film, leads having lead sections extending outwardly for bonding to a substrate and lead sections extending inwardly into the device hole. A tape carrier package (TCP) mounting process involves applying an h.f. electromagnetic field to the side opposite the lead section surfaces to be bonded to a substrate so that a solder, previously applied to the leads or the substrate, is heated and melted to bond the package to the substrate. A device, for solder bonding by h.f. heating, has an exciter for generating an h.f. magnetic field and a lead for emitting and applying the field to a solder-coated portion of an object to be bonded. USE/ADVANTAGE - The process gives reduced reject rate in bonding of multi-pin TCPs to substrates, e.g. for computers, watches and LCDs.

Keyboard supports (18) permit adjustment of the keyboard for optimal ergonomic positioning. ADVANTAGE - Keyboard and inclination of display can be freely positioned for good working arrangement.
Patent DE-4242550-A1 (DE)
Inventor: HENKE DIETRICH
IPC: E05B51/00
Filed: 1992-12-16
Abstract: Described is a device for monitoring a lock element (1) to determine whether it is closed or open. Even when manufacturing and installation tolerances are large, operation of the device is very simple, secure and reliable by virtue of the fact that a light-transmission path (7) passes through the lock element, the light path being unobstructed when the lock element (1) is in the closed position. The light path (7) has at least two optically discrete light-transmission zones (7a, 7b, 7c) disposed adjacent to each other with respect to the direction of motion of the element (1).

Patent DE-4326536-A1 (DE)
Title: Hydraulic equipment for face support in mining
Inventor: MATEJA ERNST DIPL ING
IPC: E21D23/16
Filed: 1993-08-07
Abstract: In hydraulic equipment for face support in mining, with a pressure line (P) and a return line (R), a non-return valve (11) opening towards the pressure line is arranged between the pressure line (P) and the return line (R). Damage caused by pressure peaks in the return line is thus avoided in a simple manner. Although the non-return valve (11) does not mean that the pressure peaks are prevented or rapidly reduced, but the reversal of the pressure direction is avoided, which as a rule is the cause of the damage. This is especially important for that type of slide control systems (3) in which sealing rings lie in each case between various positions of a gap through which the pressure medium flows or of such a row of holes, i.e. are crossed by the gap or the row of holes during the control action. The non-return valve (11) is preferably arranged at a control system (1), preferably in a construction unit (1, 12) together with it, and for this purpose is configured as a component (12) to be attached to a baseplate (2) of a valve unit (1). <IMAGE>

A frame of the travel unit comprises a box girder extending virtually over the entire length of the travel unit. Equipment necessary for operation, in particular travel operation, is arranged on the outside on the box girder. A driving motor, preferably an internal combustion engine, sits on one side of the box girder. The longitudinal axis of the box girder can lie eccentrically or obliquely with respect to the track predetermined by a travelling mechanism.
Patent DE-4338373-A1 (DE)
Title: Film hinge
IPC: E05D1/02
Filed: 1993-11-10
Abstract: The invention consists in an improvement in the resistance of a film hinge to tearing by virtue of the provision of reinforcement strips which run transversely with respect to the bending axis and have a greater resistance to fracture and a greater tear strength than the rest of the material of the film hinge. Said reinforcement strips may be designed as bead-like thickenings or by a different, more resistant material inserted into the film-hinge material. Reinforcement strips at the ends of the film hinge prevent lateral tearing, and reinforcement strips in the central region of the film hinge prevent further tearing when there is damage in the central region of the film hinge.

Filed: 1994-01-20
Abstract: The invention relates to a process and device for securing a pipe wall (40) to a pipe end (41) and for making aluminium heat exchangers for fluid heat conveyors. The purpose is to produce lightweight heat exchangers with high corrosion resistance and good to very good heat conductivity while maintaining adequate mechanical strength and low material costs. This purpose is achieved in that, after a pipe wall (40) has been heat treated, a drilling is made in it by the swarfless flow-drilling method in such a way that a cylindrical passage (8) is produced by the formation of a collar on both the outer and inner pipe walls, the collar-like parts (34) of the cylindrical passage are shaped swarflessly by means of a forging die (9) during flow drilling and the end (41) of a pipe to be connected is inserted into the cylindrical passage, said end being positively flanged about the cylindrical passage on the inside of the pipe by means of a flanging cone (31) arranged in the inner pipe beneath the cylindrical passage.
