Patent EP-0395415-A2 (EP)
Inventor: DOKI MASAHIKO
IPC: H05H1/46
Filed: 1990-04-26
Abstract: For greater flexibility in adjusting the radio frequency bias voltage applied to substrate 11 while maintaining a desired floating potential on the substrate, a mixing circuit 41 is used to combine and supply a DC bias voltage (via 32,33) with the RF bias voltage (via 23,20) to the substrate. A synchronising circuit confines generation and supply of the bias voltages to the active portion of each microwave pulse cycle supplied via generator 17 to plasma generating chamber 37 so that plasma is directed to the substrate 11 by a magnetic field produced by solenoid 6 during bias voltage supply to the substrate. In an alternative arrangement which dispenses with the DC bias voltage, the waveform of the RF bias voltage is varied during the active portion of the microwave pulse cycle to instigate desired effects using a high magnitude RF bias voltage confined in time to avoid undesirable side-effects.

Abstract: A die set (20) for crimping an electrical connection of a contact terminal member to an electrical conductor comprises two hermaphroditic members (22, 22′). Each die member (22) has a base section (24) including an anvil (40) extending therefrom and defining an essentially hemispheric concave crimping surface (42) having a selected desired radius. In operation, the anvils (40, 40′) are opposed so that upon completion of the crimping portion of a stroke, a symmetrical essentially cylindrical recess is defined having an axis orthogonal to the crimping axis. A contact terminal member(62) having an outer diameter at least larger than the diameter of the cylindrical recess and having a wire portion (68) inserted therein, is crimped by placing the terminal member (62) between the opposing die members (22, 22′) and parallel to the cylindrical recess axis. The opposing die members (22, 22′) are moved together, and the crimping surfaces of the anvils (40, 40′) define a crimped electrical connection (74) cylindrical in shape and having a diameter equal to the cylindrical recess diameter.

Abstract: The presence of oval defects on MBE-grown compound semiconductor (e.g., GaAs, InP, or InGaAs) epitaxial layers has proven to be a serious obstacle to the use of such material for the manufacture of integrated circuits (ICs), even though the use of such material potentially could result in ICs having superior performance. One particularly prevalent type of oval defect is generally referred to as α-type. It has now been discovered that compound semiconductor epitaxial layers that are essentially free of α-type oval defects can be grown by MBE if first at least a portion of the Ga and/or In metal crucible (24) is coated with an appropriate second metal (25). The second metal is chosen from the group of metals that are wetted by the first metal and that are less electronegative than the first metal. Aluminum is a currenlly preferred second metal. Advantageously the interior of the (typically pBN) crucible is Al-coated at least at and near the orifice of the crucible, whereby formation of drops of first metal is prevented.

Abstract: A mobile telephone apparatus for installation in a vehicle comprises a handset (1) and a cradle member (2) for releasably holding and locating the handset. The cradle member (2) includes a loudspeaker grille which, in plan view, is disposed laterally of the handset when the handset is present of the cradle. The handset does not therefore impede the sound from the loudspeaker. 
     The cradle member (2) may be substantially triangular in cross section. The handset can thus be presented to the driver of the vehicle at an optimum angle for easy physical and visual access, without the need for an additional mounting means. Furthermore, the cradle is reversible for left- or right-hand mounting, also allowing horizontal or vertical handset mounting on the dashboard.

Abstract: A communication protocol for direct communi- cations between operating system kernels of a plurality of processors in a clustered-type, shared virtual memory, multi-processor data processing system is disclosed. Each processor unit (10) includes a novel intermachine communications software system ("IMCS") which may be used by a trusted kernel of the operat­ing system of the processor, such as the page fault handler, to communicate with a service in another processor, either directly or through an intermediate processor. Communications are initiated when a user prepares a message in accordance with pre-programmed instructions from the IMCS in a standard format which contains both a data field and a header contain­ing specific control information. Once the message is pre­pared, the user calls IMCS which selects a route for the transmission of the message over a serial communications link (12) to the receiving processor using a "request to send immediate" serial link level protocol. The message is initi­ally directed to a common buffer pool previously assigned to IMCS by the various services in the receiving processor. IMCS calls special software to read the header of the message to determine the identity of the destined server (42) and to determine if the buffer in the buffer pool assigned to the called service has available buffer space to accept the message. If not, IMCS directs the sending of a negative acknowledgment to the sending processor. If sufficient buffer space is available, IMCS directs the sending of an acknowledge­ment to the sending processor. Upon receipt of the acknow­ledgement by the sending processor, IMCS calls a notifi­cation routine to inform the user of the status of the trans­mitted message.

Abstract: A TTL inverter buffer circuit is provided with a switched current that produces hysteresis in the threshold values. The current is switched on by a switch means (42) controlled by a control circuit (43) when the input logic is low and is switched off when the input logic is high. The control circuit (43) receives its sense signal from the output of a phase splitter switching transistor (18) so that when the input logic is low a high threshold is created and when the input logic is high a low threshold is created. The difference is the circuit hysteresis voltage which is dependent upon the switched current and a resistor (40).

Abstract: An assembling system of a semiconductor chip comprises a die bonding step, a wire bonding step, a molding step, a deflashing step, a lead cladding step, a marking step, a lead bending step, a testing step and a tape-wrapping step, which are arranged in the order mentioned. Each of the molding step, the deflashing step and the lead cladding step is performed by only a first treating apparatus (12, 13 or 14). Each of the die bonding step, the wire bonding step, the marking step, the lead bending step, the testing step and the taping step is performed by first and second treating apparatuses (10, 11, 15, 16, 17 or 18). The second treating apparatus is substantially equal in function to the first treating apparatus and arranged in parallel with the first treating apparatus so as to share the operation of each treating step. Where the second treating apparatuses are included in two adjacent treating steps, these two second treating apparatuses are connected in series. Where the first treating apparatus alone is included in the adjacent treating step, the second treating apparatus is connected to the first treating step.

Abstract: A broadly tuned transducer system for pulse echo ranging systems has a rigid plate (1), to a planar radiating front surface of which is applied at least one layer of acoustic coupling material (6) having a density intermediate between that of the plate and an atmosphere into which the transducer is to be coupled. Three or more driver assemblies spaced apart in a two dimensional array are rigidly secured to a rear surface of the plate, each assembly having a loading block (3) and a piezoelectric element (2) compressed between the block and the plate (1). The driver assemblies all have the same resonant frequency on axes perpendicular to the plate and are driven in phase; they occupy not less than one fifth and not more than four fifths of the area of the rear surface of the plate, which is rigid enough to prevent the excitement of significant flexural oscillations. The arrangement permits the transducer to have a large planar radiating surface whilst using quite small piezoelectric elements (2).
