Title: Transistor switching circuit
Inventor: FURUHATA SHOICHI
IPC: H03K17/64
Filed: 1991-09-02
Abstract: The negative terminal (-) of a base driving unit 1 is connected to the emitter of a switching transistor 28 or an intermediate position (M, Fig. 3) of a reactor 5 connected in series with the transistor emitter to remove or reduce a turn-on repressing function due to the reactor 5 at the time of turning the transistor 28 on, while a function to repress the radical turn-off speed of the transistor caused by the electromotive force EL of the reactors at the time of turning the transistor off is maintained. The reactor 5 is connected to the control electrode of the transistor by means of diodes 6, a capacitor (9, Fig. 5), a capacitor (9, Fig. 6) and diodes 6, a single diode (60, Fig. 8) or a zener diode (6Z, Fig. 10) and a diode (60).

Title: Plasma processing
Inventor: COLLINS KENNETH S
IPC: H05H1/46
Filed: 1991-11-05
Abstract: Plasma processing apparatus is operated under such conditions that the cathode sheath voltage developed adjacent the cathode is inversely related to the strength of a magnetic field provided within the plasma. In a plasma processing arrangement, eg. for reactive ion etching of semiconductor wafers, a wafer 46 is disposed on cathode (16) within a process chamber (14), a gas is released into the chamber, R.F. power in the VHF/UHF frequency range 50-800 megahertz is applied to the cathode to form a plasma within the chamber, and a magnetic field is provided within the chamber having flux lines substantially perpendicular to the surface of the water, and the strength of the magnetic field is varied until a desired cathode sheath voltage is attained. The includes a chamber 14, a water-supporting cathode (16) disposed within the chamber, a mechanism (32, 34) for introducing gas into the chamber, an R.F. power source (18) coupled to the cathode operating in the frequency from about 50-800 megahertz, an electromagnetic coil (60, 62) disposed around the chamber adapted to develop a magnetic field within the chamber which is substantially perpendicular to the wafer and a variable output power supply (64) coupled to the coil to vary the magnetic field strength and therefore the cathode sheath voltage within the chamber. <IMAGE>

Patent GB-2263592-A (GB)
Title: Improving stability of power supply system voltage by controlling timing of increase/decrease in power consumption of a load
Inventor: SHYU JIA-MING
IPC: H02J3/24
Filed: 1992-01-17
Abstract: A device controls a load so that the load can only turn on, or increase its power consumption, if the instantaneous (or short term average) value of the amplitude of the voltage of an A.C. or D.C. supply system is above a first threshold, and so that the load can only turn off, or decrease its power consumption, if the instantaneous amplitude is below a second threshold. The first and second thresholds may be equal to one another and equal to the long term average of the supply voltage, (Figs 1, 2). Alternatively, the first threshold may be less than the second or vice versa, (Figs 7, 8) and both may be adjusted in dependence on the highest and lowest values of the supply voltage in a given time interval. In an appliance with microcomputer control to maintain a target value of a certain parameter, the additional deviation from the target value due to the power-switching delay inherent in use of the device of the invention may be compensated by microcomputer calculation of the on-delay and off-delay averages and by advancing monitoring for suitable on/off time points by such average period ahead of the times when the microcomputer estimates that an upcoming on or off command will next be given in response to deviation from the target value.

Title: Fixture for testing for soft package leak integrity.
Inventor: HUMBARGER GRANT V
IPC: G01M3/36
Filed: 1992-09-18
Abstract: A soft package fabricated of a material with a memory is tested by placing the package in a vacuum. If there are no leaks in the package, the package undergoes a dimensional change as the vacuum is created. This dimensional change can be measured. If no dimensional changes occurs, the package has a gross leak. If the package increases in dimension and then gradually returns to its original shape, a slow leak exists. if the package grows in dimension upon creation of vacuum and retains that dimensional growth, there is no leak in the package. A test fixture 24 for measuring the dimensional changes includes a base plate 26 on which a package 10 may be positioned. A support member 36 is mounted on the base plate 26 to support a plunger rod 32 for reciprocal movement relative to the base plate. The plunger includes a first end 30 that engages the package to be tested and a second end on which a platform 44 is mounted. A counterweight is positioned on the platform. The counterweight 46 is of sufficient weight to overcome the memory force of the package material and return the package to its original dimension. A dial gauge 40 measures movement of the plunger relative to the base plate.   <IMAGE>

Title: Improvements relating to apparatus for forming scrolls from strip material
Inventor: BEECHER ROY
IPC: B21D11/06
Filed: 1994-03-10
Abstract: The invention provides that a former (A, B, C) is used for forming scrolls from strip metal (30). The former has a scroll flight which is in two parts (A, B) which are relatively movable in the direction of the axis about which the former (A, B, C) rotates to coil the strip (30) about said flight (A, B) by drawing it radially into the former. In the first stage of the process the strip (30) is coiled about the inner part (A) of the flight, the outer part (B) being held displaced axially so as not to interfere with the initial coiling by the strip (30), until the strip (30) clears the end of the outer part (B) of the flight which then moves into the plane of the inner part (A) of the flight and coiling can continue onto the outer part (B). The apparatus also includes additional mechanisms for making circle and arches from the strip and for cutting, punching, twisting and right angle bending the strip from the same drive. <IMAGE>

Title: Vehicle motion control system
Inventor: HIWATASHI YUTAKE
IPC: B60T8/1764
Filed: 1996-10-18
Abstract: In a vehicle motion control system, section 18 calculates a target rear-wheel steering angle, and section 19 sets a rear-wheel steering quantity which controls a rear-wheel steering motor 9. In addition, section 21 calculates a front-and-rear wheel steering response parameter, and section 22 calculates a front-and-rear wheel steering target yaw rate. Section 23 calculates a yaw-rate difference, section 24 calculates a target braking force, and section 25 selects a wheel to be braked. When an output discriminating section 26 determines that the yaw-rate difference is within a controllable region, section 27 outputs a signal to a brake driving section so as to add the target braking force to the selected wheel i.e inside rear for under-steer and outside front for over-steer. In a second embodiment, when an abnormality occurs in the 4 wheel-steering control, the system will switch to 2 wheel-steering.
