IPC: G11B7/123
Filed: 1997-09-22
Abstract: An optical scanning device has an objective lens for imaging light from a light source as a dot on a recording medium, a deflector located between the light source and the objective lens for changing the propagation direction of incident light, and a photodetector for error signal and h.f. signal recognition by collecting light reflected from the recording medium through the objective lens and the deflector. The novelty comprises the provision of a second harmonic generator which is located between the light source and the deflector and which has an incident light focussing lens, a nonlinear single crystal for changing the focussed light wavelength and a filter for transmitting a predetermined wavelength of the modified light.
Patent DE-19748091-A1 (DE)
Title: Waste gas treatment unit exposing flow to descending beds of activated carbon
Inventor: WATANABE TERUO
IPC: B01D53/88
Filed: 1997-10-30
Abstract: This novel unit treats a waste gas. It has a vertically-descending solid bed with horizontal gas inlet and outlet connections. Two louvered partitions between them, form a front-, intermediate- and rear chamber. Flow control units at the bases of the chambers adjust the individual rates of descent of catalyst in each. The descent velocity reduces in moving successively through the chambers in the direction of gas flow. Preferably the vertical flow rate in the second chamber is two thirds to a fifth of that in the first. The same ratios apply to vertical flowrates in the second and third chambers. The central chamber contains activated carbon. The layer thickness in the front chamber is 10%-20% of the total thickness of the moving layer. The layer thickness of the central chamber is 20% to 45% of the total thickness of the moving layer.
Patent DE-19752631-A1 (DE)
Title: Frictional error recognition device for hard disk drive
Inventor: LEE BONG-JIN
IPC: G11B19/04
Filed: 1997-11-27
Abstract: The device includes a start-up oscillator for generating a spindle motor rotation control frequency, according to a level of a spindle motor control voltage, and for controlling a rotation of a spindle motor according to the control frequency.  There is also a restart oscillator for generating a restart control signal for controlling the level of the spindle motor control voltage for a renewed starting of the rotation of the spindle motor.  A resistance is connected between the restart oscillator and ground, so that it enables a control of the level of the spindle motor control voltage, without starting the spindle motor again.  A micro-controller is connected with a node between the restart oscillator and the start-up oscillator for monitoring the level of the spindle motor control voltage, to recognise a frictional error and to provide a control signal to a voice coil motor after recognizing a frictional error.

Patent DE-19854565-A1 (DE)
Inventor: TUMBRINK MANFRED B
IPC: B01D39/18
Filed: 1998-11-26
Abstract: The invention relates to a multi-layer filter element. The invention provides a main filter layer which preferably consists of a melt-blown fleece and has an absolute filtration capability. A paper layer (2) on the clean side supports the filter element and does not contribute to the filtering of the fluid to be filtered. Said layer can therefore have a macropore structure, thereby allowing a low flow resistance. A layer (3 )on the clean side which preferably also consists of paper serves to pre-filter the fluid and to protect and support the main filter layer. The inventive design of the multi-layer filter material provides a means for economically producing filter elements, especially filter cartridges which are folded in the shape of a star, since no trellis protective layers are necessary. The invention also facilitates an improved thermal disposability of the proposed filter cartridge.

At least one branch (3) is at the outer wall of the flow channel (2), which opens into a separation channel (4) leading to a separation outlet (6).  The flow channel (2) is in a spiral, with the flow direction inwards from the outside. Several branches (3) can be along the flow channel (2), opening into the separation channel (4). A flat transit section is placed between the end of the flow channel (2) and the outlet (5) on one side and/or the end of the separation channel (4) and the separation outlet (6) on the other side, so that the outlet (5) and/or separation outlet (6) lie on a second and/or third plane, offset in parallel to the flow channel (2). The flow channel (2) has a curvature of more than 180 deg , and has a steadily decreasing cross section in the flow direction. The branch channel(s) (3) lead(s) out from the flow channel (2) at a tangent or radially. The micro-separator has a silicon structure, with a cover. The apparatus has a cascade action for separation in steps. A number of units can be assembled together in parallel. The channel walls, for the flow and branch channels, are in a variety of layer combinations using glass, silicon, metal and a polymer.

Patent DE-19857654-A1 (DE)
Inventor: RAAP MAIK
IPC: C12N15/82
Filed: 1998-12-14
Abstract: The invention concerns means and methods enabling the provision of plants showing an altered flowering behaviour, and, particularly, genetically modified plants showing an early or delayed flower formation when compared to not correspondingly modified but otherwise similar wild-type plants, as well as a tissue-specific promoter which may be utilized in a method for producing these genetically modified plants. The invention is based on the finding that the flowering behaviour of plants may be influenced by enhancing the saccharose-cleaving activity specifically in the apical meristem of the plants. In this context, an enhancement of the saccharose-cleaving activity specifically in the apoplast of the apical meristem of plants results in an early flower formation whereas an enhancement of the saccharose-cleaving activity specifically in the cytoplasm of cells of the apical meristem leads to a delayed flower formation compared with corresponding not modified wild-type plants.
Patent DE-19857904-A1 (DE)
Inventor: HOECKER HARTWIG PROF DR
IPC: A61L33/12
Filed: 1998-12-16
Abstract: Disclosed is a method for immobilizing the thrombogenic inhibitor hirudine on polymer surfaces of extracorporeal and/or intracorporeal medical objects by direct interaction or via appropriate spacer systems between functional groups of the hirudine and the corresponding functional groups of the polymers. The chemical and/or spatial environment of the hirudine functional groups is modified as regards their immobilization selectivity in a treatment step prior to immobilization. After immobilization, the chemical and/or spatial environment is no longer modified. The proposed procedure enables the functional groups needed for thrombin activity not to be bound during immobilization and are thus available for interacting with thrombin after immobilization. This causes an increased antithrombogenic and/or thrombocyte-repelling effect of the hirudine bound on the surfaces.
