Patent GB-2330643-A (GB)
Title: Piston-cylinder assembly
Inventor: MINTGEN ROLF
IPC: B60J5/04
Filed: 1998-07-29
Abstract: A piston-cylinder assembly 7 comprises a cylinder divided by a piston 17 on a piston rod 15 into two fluid chambers 23, 25. A fluid connection 21 connects the two chambers and is capable of being closed off by a valve means 19. The valve means 19 is adapted to close the fluid connection 21 for each direction of fluid flow, and comprises a main valve 27 together with a secondary valve 47, 47' for each direction of flow. The valves 27, 47, 47' are arranged in series, and a throttle means 45 is arranged between the main valve 27 and each secondary valve 47, 47'. On opening of the main valve 27 the throttle means 45 operates to reduce the pressure applied to the downstream secondary valve, and the throttling effect decreases with increasing opening of the main valve 27 to allow increasing pressure to be applied to that secondary valve. The control of the pressure applied to the valves reduces noise in operation. The assembly 7 may be used on a vehicle door or tailgate.

IPC: H03G3/30
Filed: 1999-04-30
Abstract: Described herein is a dual mode linear RF power amplifier circuit in which the amplifier can be switched between a mode in which it has high efficiency and a mode in which it has high linearity.

Title: Circuit for energising cold cathode fluorescent lamps
Inventor: LIN YUNG
IPC: G05F3/04
Filed: 1999-05-18
Abstract: Two cold-cathode fluorescent lamps 32a, 32b are connected in series with one another across a secondary winding 28 of a transformer 26, and a capacitor 36 is connected in shunt with one of the lamps 32a (or 32b), whereby the voltage produced by the secondary winding 28 and applied across the lamps 32a, 32b can be significantly less than a sum of the breakdown voltages of the two lamps. The arrangement ensures that the lamp 32a with the shunt capacitor 36 starts after a delay following starting of the other lamp 32b, the length of the delay depending on the value of the capacitor 36. The primary 24 of the transformer 26 may be driven at a high frequency of 20 to 150 KHz by a supply 22, and a DC isolation capacitor 34 may be connected in series with the lamps 32a, 32b. The capacitor 34 may be omitted if the supply 22 is a pure current source. The junction 48 between the lamps 32a, 32b may be connected to ground. The lamps 32a, 32b may provide backlighting for a liquid crystal display (LCD) of a computer.

Title: Fabricating a piezoelectric/electrostrictive thick film actuator using photolithography
Inventor: YUN SANG KYEONG
IPC: H01L41/22
Filed: 1999-06-23
Abstract: A bottom electrode 20 is formed on a vibrating plate 10. Over the bottom electrode, a photoresist 14 is coated, exposed to light and developed to form moulds. Ceramic paste 16 is prepared by mixing a ceramic oxide powder and a ceramic sol solution. The ceramic oxide powder has a particle size of 5 m or less and is prepared from Pb and Ti-based ceramic oxide powder by a non-explosive oxidation-reduction combustion reaction at 100-500 {C while the ceramic sol solution, identical or similar in composition to the ceramic oxide powder, uses water or an organic solvent as a base. The ceramic paste is placed into the moulds to form a piezoelectric/electrostrictive film by sintering at 100-300{C to sinter the film. Finally, a top electrode 18 is formed on the film. Alternatively, the bottom electrode may be omitted if the vibrating plate is metallic or conducting. A micro actuator formed by this process has high aspect ratio patterns, improved bonding properties and improved protection.

Title: Optical communication system
Inventor: SHIBATA NOBURU
IPC: H04B10/29
Filed: 1987-01-21
Abstract: PURPOSE:To attain excellent reception even with increased number of subscribers by using a Brillouin optical amplification so as to receive selectively only signal component of a specific channel frequency from a subscriber side. CONSTITUTION:For example, when a subscriber operates a stimulated light source 10 in a subscriber receiver 6-i, the light radiated from the light source 10 and made incident in an optical coupler 7 through an optical isolator 9 generates a Brillouin optical amplification region in the optical fiber line 5-i and the signal light propagated through an optical fiber 5-i. The amplified light is converted into an electric signal by a photodetector 8 and the original electric signal waveform is restored by a signal demodulator 11. Only the signal component of a prescribed channel frequency is received selectively by using the Brillouin optical amplification from the subscriber side. Thus, even when number of subscribers is increased, excellent reception is attained.
