Patent DE-4310621-A1 (DE)
Title: Rotating piston machine for compression of gaseous mediums - has intake and discharge sockets relatively offset on housing parallel to rotor axis
Inventor: FREY MICHAEL
IPC: F04C18/22
Filed: 1993-03-31
Abstract: The machine has a common housing for rotors (1,2), which rotate about stationary shafts. The rotors mesh to form working chambers of varying sizes. Intake and discharge apertures (3,4) in the housing wall connect the chambers via channels (5,6) to intake and discharge sockets (12,13). A flow connection (19) between the channels has a control (20) for pressure regulation. The sockets are located relatively offset on the housing, in a direction parallel to the rotary axis of the rotors. One of the channels is curved, and encloses the cylindrical housing chamber (11) up to the associated intake and discharge socket to approach the other channel. ADVANTAGE  - Permits low loss and low noise pressure control in discharge socket.

Title: Conductor for bonding in semiconductor chip - has perforated end section through conducting layer for connection to contact bumps on semiconductor chip
Inventor: YANO MASUYUKI
IPC: H05K3/34
Filed: 1993-04-27
Abstract: The conductor is part of a film contact tape (4) which is fixed to a carrier (10). The film contact tape comprises a carrier tape and a number of conductors (1) which have a perforated end portion. A contact stage (13) carrier the semiconductor chip (2) on which contact bumps (3) are formed. A rotary mechanism (13a) is used to turn the contact bumps, and a vertical setting mechanism (14) brings the bumps and the perforated section into contact, such that a force exists which deforms the conductor (1) so that the ends of the conductors press onto the contact bumps. Meanwhile, the semiconductor chip is heated and the fused bumps penetrate into the perforations to form electrical contacts. ADVANTAGE - Prevents bonding of conductor causing reduction in connection strength. Does not use press head.

Title: Device for recording and reading out transponders which move in relation to this device
Inventor: HOEFGEN GUENTER DR ING
IPC: G01S13/76
Filed: 1993-08-05
Abstract: A device for recording and reading out information-carrying transponders (T) which move in relation to this device, which device selects transponders which are to be read out according to their distance and is thus unaffected by reflections or unwanted transponder responses from distance zones which are located at a shorter or longer distance. Two phase modulators (PM1, PM2), one of which is disposed in the transmit arm and the other in the receive arm of the read device, are controlled with the same pseudo-random code, although the second phase modulator is time-delayed. Receive signals reflected from a transponder or from other objects are evaluated only if the sum of the transit times of the transmitted RF signal and the signal reflected back to the read device is equal to the delay of the modulation signal fed to the second phase modulator. The device can be used in a stationary manner to read out transponders connected to mobile objects or in a mobile manner, e.g. on trains to read out fixed route markers. <IMAGE>

Inventor: PEACE STEVEN L
IPC: G11B5/55
Filed: 1994-08-25
Abstract: A magnetic head positioning mechanism for a tape backup device includes a carriage 14 carrying the head 10 that has an opening (Fig 4, 15) with a substantially conical surface, a guide rod 30 extending through the carriage that restricts translation of the carriage to motion along a predetermined axis, a lead screw 20 extending into the opening in the carriage that is driven by a stepper motor 50 via a gear train 51, 22, a follower nut 40 threaded on the upper portion of the lead screw for translating the carriage and head along the axis as the lead screw is rotated by the stepper motor, and a spring (Fig. 1 60) for urging the carriage into contact with the follower nut The base end of the lead screw 20 has a conical indentation 24 that contacts and rotates on the rounded end (Fig. 3 6) of a protrusion 4 extending from the chassis 2. The relative positions of this indentation and protrusion can be reversed, if desired. The follower nut includes a rounded (or spherical) surface (Fig. 4 42) for contacting the conical surface (Fig 4 15) within the opening in the carriage. The combination of the conical indentation at the base of the lead screw and the rounded surface on the follower nut at the upper portion of the lead screw allows the lead screw to pivot and self-align. This relaxes the required tolerances for alignment and simplifies assembly of the device. <IMAGE>
