Patent GB-2104319-A (GB)
Title: Fluorescent lamp starter apparatus
Inventor: TSUONG TSUAN CHEN
IPC: H05B41/04
Filed: 1981-08-25
Abstract: To provide a high voltage starting impulse to fluorescent lamp 10 without the use of a transformer in the circuit, the starter circuit comprises a voltage doubling and rectifying circuit including capacitors denoted by prefix C and diodes denoted by prefix D connected in series and parallel with the AC input. Resistor R1 dampens the input current and thus protects diodes D1 and D2 from damage, resistor R2 prevents excessive build up of voltage across the lamp 10 which might damage the lamp 10 and resistor R3 provides a current sink to speed extinction of the lamp when the current is switched off. Once lit, the lowered impedance of the lamp lowers the output voltage of the circuit. <IMAGE>

Title: Solid state image sensor
IPC: H04N5/369
Filed: 1981-11-09
Abstract: A solid state image sensor, in which the same gate voltage is applied through a gate insulating layer to a channel area and an over-flow control gate area, both provided in a semiconductor substrate, is disclosed. In this case, the substrate concentration adjacent the area beneath the over-flow control gate area is made different from that adjacent the area beneath the channel area to reduce the gate voltage dependency of the potential at the over-flow control gate area as compared with that at the channel area, whereby the maximum handling charge upon the charge transfer mode is made more than that upon the light receiving mode.

Patent GB-2089438-A (GB)
Title: Wave energy converting system
IPC: F03B13/12
Filed: 1980-05-21
Abstract: A device for the generation of energy from the energy in waves in a body of liquid comprises a buoyant structure (30) which is positioned in the body of liquid so as to heave up and down under the action of heave wave forces. The buoyant member is provided with a rope, cable, cord or the like (12) which extends downwards through a gland (28) to a submerged energy conversion apparatus such as a piston (22) and cylinder device (14). The lift of the buoyant member effects displacement of the piston in a submerged cylinder and from such piston movement fluid is pumped to drive a pelton wheel (38) located in a submerged air pocket (36), and the pelton wheel is connected to drive an electrical generator (43). As the buoyant member moves downwards, the piston moves downwards in the cylinder and a one-way valve arrangement (23) allows fluid to flow into the cylinder. During the upward pumping stroke of the piston, the fluid is pumped out of the cylinder and drives the pelton wheel. An accumulator (900) is coupled to the piston and cylinder to be charged when the piston and cylinder also pumps to the pelton wheel, and when the piston and cylinder moves in a pumping stroke the accumulator discharges to drive the pelton wheel. The buoyant member is biased downwards by elastic straps (300) or the like which preferably are attached to the underside of the buoyant member.

Patent GB-2132789-A (GB)
Title: Method of pattern generation
Inventor: DOLAN GERALD JOSEPH
IPC: H01L21/027
Filed: 1983-11-18
Abstract: A pattern generation technique is described in which a pattern is produced in a radiation sensitive material by writing only the perimeters of the desired features, and effecting a toning step to define the full pattern. This enables a slow but high resolution technique e.g. electron beam lithography, to be used to define the outline of the pattern 9 in a resist 5. In one embodiment after development of the resist, removal of the bared underlying chrome layer 3 and removal of the remaining resist a chrome layer with a pattern of ditches defining the features is produced (Figure 4). By differentially etching or plating the layer inside and outside the perimeters the full feature 7 is formed (Figure 5). Various etching techniques are described including applying different electrical biases to the areas inside and outside the perimeters, e.g. by contacting some areas with Al or Ln, before immersion in etchant (dilute HCl). In a second embodiment selected areas are contacted with Cu and the chrome etch is cerium based. <IMAGE>
