Title: Particle beam surface analyzer
Inventor: HAZAKI EIICHI
IPC: F16K3/18
Filed: 1990-06-13
Abstract: In a particle beam surface analyzer, having a partition wall separation a vacuum space, an opening that is provided in a partition wall through which the particle beam is taken out, a seal member which is moved along a seal surface of the seal member and seals the opening, a condenser lens which converges the particle beam onto the sample, and detector for detecting a physical quantity from the sample when the particle beam is irradiated on the sample, the surface analyzer further has a movable shift member that pushes one side surface of the seal member along the seal surface of the seal member and a stopping member which the other side surface of the seal member having a predetermined angle being larger than 55 DEG  and smaller than 75 DEG  to the seal surface is abutted so as to move the seal member along the other side surface till the seal member reaches the openings, whereby resultant forces between the seal member and the seal surface in the side of the one side surface is equal to that in the side of the other side surface. As the predetermined angle is larger than 55 DEG  and smaller than 75 DEG  to the seal surface, the abrasion and seizure of the seal member are prevented and the contamination of the sample is lessened.

Patent GB-2264808-A (GB)
Title: Plasma mass spectrometer
Inventor: OISHI KONOSUKE
IPC: H01J49/10
Filed: 1993-02-18
Abstract: In a microwave induced plasma source the aerosol generator 5, 3 is shielded from stray microwaves by a shield 24. A plasma mass spectrometer generates an aerosol of a sample, by dissolving the sample in a liquid solvent 1, and spraying the liquid into a spray chamber 5 via a nebulizer 3. The solvent condenses in the spray chamber and an aerosol of the sample then passes through a supply tube 25 to a plasma torch 6. Microwave power from an output 8 on the plasma torch 1 converts the aerosol to a plasma, and the plasma passes to an analyzer 14. If microwave radiation reached the spray chamber 5, it would cause heating of the solvent which may evaporate it so that the solvent would be present in the plasma. Therefore there is a wall 24 between the spray chamber 5 and the plasma torch 6 and microwave output 8 which blocks such microwave radiation. Although the aerosol supply hole 25 creates an opening in the shield wall 24 microwaves will not propagate through it if it is sufficiently small. In an alternative arrangement, Fig 2 (not shown), the spray chamber 5 is also enclosed in the casing 23 with an internal wall (27) shielding it from the microwave output 8. <IMAGE>

Title: Communications system with priority scheme for reduced access delay
Inventor: KASHI HAIM
IPC: H04L12/403
Filed: 1994-10-04
Abstract: A communications system is described having a central station and a number of remote units arranged for communication over a common communications channel. Each remote unit has a predetermined priority parameter and each remote unit has a processor element (30), a receiver (28), a channel monitoring circuit (26) for sensing when the channel is free and a transmitter (29). The processor element is arranged to identify from received data a priority parameter of a unit currently transmitting. A comparison is performed between the priority parameter of that unit and the predetermined priority parameter, to initiate a timer function (108) in response to the channel monitoring circuit when the channel monitoring circuit indicates that the channel has become free, and to reset the timer function if the channel monitor circuit indicates that the channel has become occupied. The timer function times a selectable period which is dependent on the comparison and the timer function causes activation of the transmitter when the timer function times the selectable period. The invention is applicable to, but not limited to use in supervisory control and acquisition-of-data (SCADA) systems. <IMAGE>

Patent GB-2299224-A (GB)
Title: Motor bearing and/or winding protection circuit
Inventor: ORMISTON JIM
IPC: H02H7/085
Filed: 1995-03-11
Abstract: The protection circuit has temperature sensors 1 located close to the bearings and windings which send a voltage signal of actual temperature to comparators 2,3,4,5,6,7 and 10 and sample and hold circuit 11. If the voltage signals exceed pre-set limits then the comparator outputs are enabled and signals are sent to trip unit 12 and warning indicators 14. The sample and hold circuit 11 is switched by a clock input 13 at pre-set timing intervals, and sends a voltage signal to the comparator 10. A desired temperature limit is added to this signal which is held for the duration of the hold cycle and continually compared to the voltage signal received from the sensor 1. If the temperature rises excessively during this period, the comparator output is enabled and a signal is sent to the trip unit 12.
