Patent NL-8602276-A (NL)
IPC: G11B15/18
Filed: 1986-09-10
Abstract: When a record carrier (14) is inscribed for an n <th> time (n>1), in which record carrier the information is recorded in fir  blocks (FB) in tracks (T1, T2, ...) which adjoin each other and which are inclined relative to the longitudinal direction of the record carrier, each track containing at least one first block (FB1) of information and at least one second block (SB1) of tracking signals ( f), only the first blocks of new information are written over the first blocks recorded previously in the tracks and the second blocks of tracking signals are not erased from the record carrier. These second blocks are employed for the purpose of tracking when the record carrier is inscribed for the n <th> time. In this way it is achieved that the new information is recorded exactly in the original tracks, so that perfect inserts can be made.
Patent NL-8701528-A (NL)
IPC: G11C19/28
Filed: 1987-06-30
Abstract: The invention relates to a semiconductor device comprising a charge transfer device having an output stage (8). The output stage (8) comprises a read-out zone (9), a feedback capacitor (11) and an amplifier (10). An inverting input (15) of the amplifier (10) is connected to the read-out zone (9) and an output (16) of the amplifier (10) is fed back via the feedback capacitor (11) to the inverting input (15). According to the invention, the capacitor (11) is a capacitor of the MOS type and means are provided by which during operation of the charge transfer device the surface potential of a surface region (13) in the capacitor (11) is solely determined by the potential of the read-out zone (9). Consequently, the capacitance of the feedback capacitor (11) is dependent upon the potential across it, as a result of which there is a linear relation between the charge supplied to the read-out zone (9) and the voltage variation across the capacitor (11). Thus, this voltage variation is an accurate measure for the supplied charge.

IPC: B65G51/00
Filed: 2004-11-19
Abstract: The method and the device are used in mechanical engineering for the transportation of liquids by means of compressed air, both of condensation, and of other liquids which can substitute the existing and the quickly wearing off devices having spring-and-lever mechanisms and ensure smooth and emergency-free operation of the pieces of equipment. By the method the liquid is fed to a specified level into a vessel wherein at least two changeable volumes can be formed, after which the liquid is pushed out and transported by means of changeable effective operational volume of the compressed gas, or steam, respectively. In the vessel, at least two changeable gas volumes V1 and V2 are formed, which act by different pressure p1 and p2 on the liquid. The liquid level in both volumes is changing in a stepping manner, and the switching of the processes - feeding of the liquid and filling the vessel, as well as the pushing out of the liquid to the user - is effected by the established pressure difference p1 and p2 between the gas volumes V1 and V2. The device for liquid transportation by compressed gas or steam takes the form of a closed vessel (1) having an input (6) and output (7) for the liquid, and input (4) and outlet (3) for the compressed gas or steam. A second volume is formed in vessel (1), and a cylinder (2) is provided, opened from its lower part and mounted along the axis of vessel (1) with a facility for movement in vertical direction.
