Title: Method and apparatus for exposing photoresist by using an electron beam and controlling its voltage and charge
IPC: H01J37/317
Filed: 1985-06-12
Abstract: A method and apparatus are disclosed for exposing photoresist using an incident electron beam during the fabrication of a semiconductor device. The method includes the steps of coating the substrate (50) with a photoresist (51) that is exposed in response to an electron beam (52). The electron beam is projected onto the photoresist (51) and deflected to trace a pattern. The voltage and the amount of charge of the electron beam are controlled as it is deflected so that the energy incident upon the coated photoresist is correlated to variations in the photoresist thickness to expose photoresist with minimal penetration therethrough to underlying structures.

Title: Encoding method
IPC: H03M7/46
Filed: 1985-06-24
Abstract: An encoding method for an anologue waveform, such as a speech waveform comprises deriving a digital data stream from the waveform, dividing the digital data stream into a number of successive time frames of equal period and storing the data. A stream of time encoded symbols is also derived from the analogue waveform, divided into successive time frames corresponding to those of the digital data stream. The distribution of the time encoded symbols for successive time frames is determined and a digital data stream for subsequent decoding is reconstructed from the digital data stored in combination  with derived digital data which is dependent upon the results of the comparison of the encoded symbols.

Title: Device for cutting off an involontary connection at a telephone apparatus by the exchange in a system with two automatically alternatively connectable parties on a line
IPC: H04M1/715
Filed: 1986-08-06
Abstract: The telephone stations (SP1, SP2) can be connected via a change- over switching device (W) to the telephone line (a1, b1) by means of which, when the loop is closed in a telephone station, this station is in each case connected to the telephone line. Each of the telephone stations (SP1, SP2) is connected via a resettable disconnecting device (K1, K2) to the change-over switching device (W). When a loop is closed in a telephone station due to the fact that a handset has not been replaced, a set signal, by means of which the telephone stations (SP1, SP2) are disconnected from the change-over switching device (W), is supplied to the disconnecting devices (K1, K2) due to a control signal coming from the exchange. By means of a monitoring device (16), a reset signal is transmitted to the disconnecting device (K1, K2) which is associated with the telephone station in which there is no loop closure and this telephone station is reconnected to the change- over switching device (W). The voltage on the telephone line is continuously monitored by a short-circuit monitoring device (11-12) and in the case of a short circuit without the exchange becoming active, the defective telephone station is disconnected from the change-over switching device (W). <IMAGE>
Patent EP-0222443-A3 (EP)
IPC: G06F9/46
Filed: 1986-10-31
Abstract: A multiprocess computer executes operating system 
routines and user processes. One specific peripheral apparatus has a 
preferential status in that it may emit attention interrupts and/or 
completion interrupts that relates to an I/O-operation. Only those 
interrupts find preferential treatment in that the associated interrupt 
has a higher priority level than the one(s) corresponding to the 
majority of the operating system routines. In contradistinction to all 
other user process interrupts the above attention and completion 
interrupts are executed in their own hardware and software context, to 
which effect the latter context is temporarily activated, and after 
execution of the interrupt procedure restored to its previous status. In 
this way dialog with the peripheral may be executed real-time, while the 
"own" context greatly facilitates programming. An upgraded driver 
program is also presented.

Abstract: A process for etching SiO₂ using either silicon rich SiO₂ or 
Si₂N₄ as an etching barrier over a substrate. Selectivity is ob­
tained between the two dielectric materials, silicon dioxide and 
silicon nitride or silicon dioxide and silicon rich silicon dioxide 
wherein the oxide etches considerably faster than nitride (or 
silicon rich silicon dioxide) because of the selectivity of oxide 
to nitride. A further object of the present invention is to provide 
an etching process wherein the silicon dioxide on the 
substrate is directionally etched in a fluorocarbon gas to form 
silicon dioxide spacers on a substrate, and the substrate 
surface ist protected by an etch stop composed of the silicon 
nitride or silicon rich silicon dioxide material.

Title: Control circuit for a switching power supply with a sinucontrol circuit for a switching power supply with a sinusoidal input current for transforming a sinusoidal ac vosoidal input current for transforming a sinusoidal ac voltage into a regulated dc voltage ltage into a regulated dc voltage
IPC: H02M3/156
Filed: 1987-06-01
Abstract: A control circuit for controlling a known active harmonic filter operating as a step-up converter in a power supply with sinusoidal network current input and a power factor of almost unity. The step-up converter comprises: a main rectifier, a storage inductance (LS), a cross-connected high-speed transistor (TQ), a diode (D1) and a power storage capacitor (CL). The high-speed transistor (TQ) is controlled by a first threshold switch (STc) whose input is controlled by a control capacitor (C12) coupled to receive a signal representative of instantaneous rectified d.c. output voltage (UE), instantaneous power output voltage (Uo) and a signal representative of the charge state of the inductance. The inductance charge signal is obtained from a voltage jump (ringing voltage) between the inductance and the diode (D1) by sensing a flank of an oscillation voltage occurring at the diode by a RC circuit (R8, C10), which triggers a second threshold switch (STa) to control charge reversal and recharge of the capacitor (C12), thus determining the time instants of operation of the first threshold switch to control the cross-connected electronic switch (TQ) to conduction, and hence re-storing of electrical energy in the inductance.

Title: Block pattern detection circuitry
IPC: G11B20/12
Filed: 1987-07-24
Abstract: Block pattern detection circuitry for the read subsystem of a streaming tape drive system comprises a state machine (20), a pattern decoder (30), a tape mark detector (40), a block/gap filter (50), a block/gap meter (60), a verify count section (10), and a block read/verify section (80). The incorporation of a hardware state machine (20) within the block detect circuitry permits the application of historical detect data in the interpretation of present detect data. This provides more certain pattern recognitions. Also, state data is fed back to the block/gap filter (50) allowing precise block boundary triggers which are used by position capture circuitry and the drive controller to effect more precise re-try positioning. The use of the block/gap filter (50) increases the detect circuitry's immunity to noise. The advantage is enhanced where the block/gap filter (50) uses stochastic thresholding, which is also advantageously employed by the tape mark detector (40).

Title: New lock arrangement
IPC: B65D71/00
Filed: 1987-02-10
Abstract: This relates to a lock arrangement particularly adapted for use in locking together closure panels of paper board cartons and the like. The lock arrangement utilizes a conventional basic type of lock including a primary locking tab and a secondary locking tab. The primary locking tab engages in a cutout having as part of its boundary a straight line primary locking shoulder. The new feature of the lock arrangement is an arrangement for receiving the secondary locking tab. This arrangement is in the form of a cut line which will define an opening through the associated closure panel and also define a secondary locking ear for engagement beyond a prong on the secondary locking tab. The closure panel in which the cutout and the cut line are formed is provided adjacent the cut line either with an opening or a hinged locking flap with there being between the cutout and either the opening or the locking flap a narrow strap. When a nose of the secondary locking tab engages the panel between the narrow strap and the cut line, the panel is locally bowed through a twisting of the narrow strap facilitating the opening of the panel along the cut line so as to automatically receive the nose of the secondary locking tab.

Abstract: Surfaces such as lead alloys, to which paint does not 
adhere well, have previously been shot blasted with an 
abrasive, cleaned and then coated with the pain or similar 
coating. It is now found that dry epoxy powder may be 
projected at high pressure at such surfaces and will form a 
conditioning layer to which paint will adhere well. The 
conditioning layer penetrates into the surface to form a 
mechanical bond. In one example, dry epoxy powder paint is 
projected by air at 5.5 bar pressure onto terne steel to 
condition it. This is followed by electrostatic coating with the 
same epoxy powder paint and heat treatment.

Title: Electronic time switch with a programme carrier which can be switched from a short to a long time interval programme
IPC: G04C23/08
Filed: 1988-03-03
Abstract: In the electric timer having an analog time display and a disk-or ring-shaped program carrier programmable by means of slide contacts, the program carrier is settable selectively by means of a switching device to different synchronous speeds of rotation, namely one revolution per week or one revolution per day. To this end two drive rings concentric with the axis of rotation of the program carrier are provided, of which one revolves at a speed of one revolution per day and the other at one revolution per week. The program carrier can be coupled selectively with one of the two drive rings by means of a coupling member adjustable to radii of different size on the same radius vector. While the drive ring revolving at the slow speed can be coupled with the program carrier in seven different angular positions, for the drive ring which revolves once a day only a single angular position exists in which it can be coupled with the program carrier.

Filed: 1988-11-25
Abstract: A tuned oscillator comprises an active element such as an FET (1) 
for oscillation and an YIG thin film ferrimagnetic resonator (2) 
connected to the FET (1) as part of a feedback circuit for the FET (1). 
The YIG thin film resonator (2) includes an YIG disc (2a) and has a 
bias magnetic field (H) applied perpendicular to a surface of the YIG 
disc (2a) to set the resonant frequency. The magnetic field (H) is 
generated both by a permanent magnet (4c) for providing a fixed 
component of the field and also by a coil (4b) for providing a variable 
component of the field. The resonant frequency is stabilised by a PLL 
circuit (5) connected to an output of the oscillator and with a 
feedback connection to the coil (4b). Since the YIG thin film tuned 
oscillator has a high Q value, high quality communication signal 
processing can be achieved. The YIG tuned oscillator may be used as a 
local oscillator for a transceiver.
