Patent EP-0336754-A2 (EP)
Inventor: KARZ ROBERT S
IPC: G03G15/20
Filed: 1989-04-06
Abstract: A control arrangement for the heater of a fuser roll (12) for fixing toner images to copy substrates. A light chopper (36) rotates with the fuser roll and generates signals which actuate a switch (42) operably coupling a power source (46) with the fuser roll heater (30). The heater (which may be in the form of a filament lamp) is energized at maximum power at a duty cycle of 10 %: this provides for a fail-safe arrangement in the event that the switch (42) short circuits because the heater then fails through being overloaded before the fuser roll becomes overheated.

Abstract: A linear accelerator (30 in Fig. 2) for charged particles is constructed of a plurality of transmission line sections (41-1, 42-1)---(41-5, 42-5) that extend between a power injection region (36) and an accelerating region (37). Each line section (41-1, 42-­1)---(41-5, 42-5) is constructed of spaced plate-like conductors and is coupled to an accelerating gap located at the accelerating region (37). Each gap is formed between a pair of apertured electrodes, with all of the electrode apertures (43) being aligned along a particle accelerating path (24). The accelerating gaps are arranged in series, and at the injection region (36) the line sections (41-1, 42-1)---(41-5, 42-5) are connected in parallel. At the injection region (36) a power pulse is applied simultaneously to all line sections (41-1, 42-1)---(41-5, 42-5). The line sections (41-1, 42-1)---­(41-5, 42-5) are graduated in length so that the pulse reaches the gaps in a coordinated sequence whereby pulse energy is applied to particles as they reach each of the gaps along the accelerating path (24).

Abstract: The invention relates to a pneumatic fertilizer spreader, the dispensing elements of which can be stopped at least in groups by interrupting the drive and the working width of the pneumatic fertilizer spreader can thus be reduced in steps. So that the working width can be reduced or increased in the smallest possible steps, in one embodiment each pipeline is assigned a respective dispensing element and each dispensing element can be stopped independently. In another embodiment, at least some of the dispensing elements are assigned slides, by means of which the dispensing elements or outflow orifices can be covered. Here, the slides are so designed that at least half the width of the dispensing elements can be covered in each case, with the result that, in addition to the interruption of the drive of the dispensing elements, the working width can be reduced in further steps by covering the dispensing elements.

Abstract: An oxide superconducting film is formed using laser deposition of applying an excimer laser beam (1, 21) onto a target (3, 23) through a converging lens (2, 22) and depositing atoms and/or molecules scattered from the target (3, 23) on the base material (5). The converging lens (2) is prepared by a cylindrical lens, or the converging lens (22) is moved, so that a portion (4, 25) irradiated with the laser beam (1, 21) on the target (3, 23) is linearized. Thus, it is possible to form an oxide superconducting film which is homogeneous over a region having a relatively large area on the base material (5) not only in film thickness but also in property.

Abstract: A push button variable resistor device includes a hollow push button seat member confining a receiving space 10, and at least one resistor piece (3, 3a, 3b, 3') fixed inside the seat member. The resistor piece (3, 3a, 3b, 3') has a contact portion (30, 30', 3d) and at least one leg portion ( 32, 34, 3f) projecting outward through a base portion 12 of the seat member. A spiral spring resistor (4, 4') is disposed inside the receiving space 10 of the seat member above the resistor piece (3, 3a, 3b, 3d). The spring resistor (4, 4') has a plurality of concentric turns of varying diameters. A push button 5 is slidably fitted through a button opening 23 of the seat member. The spring resistor (4, 4') has a topmost turn 41 cooperatively associated with the push button 5. The push button 5 is externally pushed to compress the spring resistor (4, 4') to cause the concentric turns to contact the resistor piece (3, 3a, 3b, 3d). The contact area between the spring resistor (4, 4') and the resistor piece (3, 3a, 3b, 3') varies according to the degree of depression of the push button 5 to correspondingly vary the output resistance of the variable resistor device.

Abstract: A particle detector (12) for detecting particles of blood components in an electrolyte employs a minute hole (16) through which a fixed quantity of the material is drawn. Electrodes inside (50) and outside (52) the detector pass an electric current through the minute hole (16). When a particle passes through the hole, it partially blocks the hole, whereby a sharp change is experienced in the amount of current passing through the electrolyte. A syringe fluid path (32) in the detector enters the fluid path for the test fluid (20) at right angles thereto. The inside electrode (50) is disposed in the syringe fluid path near its junction with the fluid path for the test fluid (20). A colorimeter (40) is placed in series with the flow of the test fluid to measure the concentration of hemoglobin in the test fluid. Automated control of the particle detector is provided by a plurality of cams driving a corresponding plurality of pistons. One of the pistons serves as a syringe (64) for pumping test fluid during a test and for pumping purge fluid for cleanup prior to the next test. The remaining pistons, with interconnecting chambers, perform valve functions.

Abstract: An optical head apparatus (2) of this invention has an object lens (14), arranged to oppose an optical disk (50) and to be perpendicular to a plane including a normal to a central beam of laser beam and movable in a desired direction, and a mirror (8), arranged at an angle of 45° with respect to the central beam of the laser beam, for guiding the laser beam toward the object lens. The mirror (8) and the lens (14) are integrally supported and are biased so that the gap between the lens and the optical disk (50) is constant. When the optical disk (50) is rotated while it vibrates or is inclined, error rates during data recording and data reproduction are increased. According to this invention, the support (30) member for supporting the mirror (8) and the lens (14) is rotated within a plane perpendicular to the central beam in accordance with the vibration or inclination of the optical disk (50). As a result, even when the object disk is inclined in accordance with the inclination of the optical disk, coma-distortion is decreased.

Abstract: An improved video signal recording system for recording a full bandwidth video signal on a limited bandwidth medium includes an encoder 10, coupled to an input terminal 5, for adaptively processing a composite video signal in response to a motion representative signal, and producing two signals; a luminance signal Lr, having attenuated high frequencies subsampled so as to be folded into a spectral hole in the low frequencies, and being bandwidth limited to the limited bandwidth of the recording medium, and a combined signal C+Mr including a chrominance and a motion component. Luminance signal recording circuitry 20 records the folded luminance signal on the medium, and chrominance signal recording circuitry 30 records the combined chrominance and motion signal on the medium. An improved video signal playback system for reproducing such a prerecorded video signal is also disclosed. The playback system consists of a luminance signal playback circuit 60 for retrieving the prerecorded luminance signal Lpb from the medium, and a chrominance signal playback circuit 80 for retrieving the prerecorded combined chrominance and motion signal C+M from the medium. A decoder 70 extracts the motion signal and the chrominance signal from the combined chrominance and motion signal and an unfolding circuit extracts the luminance high frequencies from the prerecorded folded luminance signal and adaptively regenerates the full bandwidth luminance signal in response to the motion signal. This regenerated full bandwidth luminance signal is combined with the chrominance signal to reproduce the originally recorded composite video signal. A recording medium previously recorded by such a recording system is capable of being played back on a standard playback system without objectionable artifacts in the reproduced image.
