Title: Integrated circuit FET photodetector - has polycrystalline silicon transparent gate electrode on silicon oxide layer for positive charge on boundary surface
Inventor: SCHULZ MAX PROF DR
IPC: H01L27/148
Filed: 1980-08-08
Abstract: The photodetector which can be a depletion mode field effect transistor in integrated circuit form, with a silicon base, has a transparent gate electrode. This can be of polycrystalline silicon, and positioned on a thin Si02 layer through which the radiation can also pass to excite electrons in the boundary surface between this layer and silicon layer below. This results in a more positive charge on the boundary. The source and drain electrodes are each side of this strongly doped layer. This is achieved by ion implantation of a foreign substance followed by heat treatment to obtain the required electrical and optical properties. Caesium ions can be used for implantation. The channels in the transistor structure can be formed by a p-type doped zone in an n-type silicon substrate. The device can be used in an X-Y addressing system.

Abstract: In a new process for the prodn. of 2,6-dichloropyrazine (I) by chlorination of a soln. of monochloropyrazine (II) in dimethylformamide with gaseous chlorine, a mixt. of high-boiling paraffin hydrocarbons is added to the reaction soln. before the chlorination. Pref. paraffin hydrocarbon mixts. are those of b.pt. more than 300 deg.C. The hydrocarbon mixt. is pref. used in an amt. of 0.5-10 g per gramme (II), the amt. of (II) being 1 g per 0.5-10 g dimethylformamide, provided that the amt. of paraffin hydrocarbon mixt. is at least equal to the amt. of dimethylformamide. Reaction temp. is pref. 10-120 deg.C. (I) is useful as an intermediate, e.g. for the antibacterial sulphonamide 2-sulphanilamido-6-chloropyrazine. Addn. of high-boiling paraffin hydrocarbons to the reaction mixt. eliminates the risk of explosion without reducing reaction rate, so that the process is suitable for use on an industrial scale.

Title: Method of controlling a filter
Inventor: BATYREV RUSLAN IVANOVIC
IPC: B01D37/04
Filed: 1981-04-27
Abstract: In the method of controlling a filter, the filter control is carried out according to the invention according to the criterion ( phi ) of the efficiency of the filtration process, which represents the maximum filter output (V) at minimum inherent costs of the filter operation over a series of filtration cycles. After reaching the extreme value of the efficiency criterion ( phi ), the filter (2), according to the number of cycles (n), is shut off for complete regeneration of the filter elements. The transition to carrying out auxiliary operations is performed after reaching the extreme value of the efficiency criterion ( phi ) as a function of the filtration time (t). The motive force (P*) of the filtration process is chosen after reaching the extreme value of the efficiency criterion ( phi ) depending on the pressure drop (P) at the filter (2). <IMAGE>

Title: Multi-layer sack, and method and device for its manufacture
Inventor: MATTIEBE GUENTER
IPC: B31B170/20
Filed: 1981-05-14
Abstract: In this multi-layer sack, an inner latch (4, 5) which seals the sack bottom in the region of the bottom edges is formed by tabs (9, 9' and 10, 10') which start from the separating line (3) of the inner web of material (1) and are arranged in such a way that they lie congruently on one another after the forming of the webs of material to form the tube and are bonded to one another at this point. The inner latch can thus be formed without additional use of material and it automatically maintains its correct position in the bottom. The transverse edges of the corner folds can also be covered by it. A sack of this type can also be produced quickly and simply since, for this purpose, the appropriate incisions for forming the tabs only need to be made in the inner layer (1) of material. The device for carrying out the method only requires an additional cutting device for the incisions and a folding device and a gluing device for the tabs formed. <IMAGE>

Title: Pedal cycle
Inventor: HOFGAERTNER KURT
IPC: B62M17/00
Filed: 1981-05-22
Abstract: In the case of a pedal cycle with bevel-gear drive, particular problems arise if the hub (7) of the rear wheel is intended to be spring-loaded and, for this purpose, is intended to be movably mounted on a swinging fork (6). Spring-mounting of the rear wheel in this manner in a pedal cycle with bevel-gear drive can be achieved in an operationally reliable manner with only minimum additional expense if at least one section of a swinging-fork arm (6a) is formed by an in particular tubular bearing housing (22) for the drive shaft (15) of the gear mechanism, and the swinging fork (6) is held such that it can swivel around the bottom-bracket bearing spindle (4). As a result, when spring movements of the hub (7) occur, no changes in the toothed engagement between a drive wheel (11) on the bottom-bracket bearing (4) and the input pinion (14) of the deflection gear mechanism take place, whereas the overlying oscillation movement which occurs is of too low amplitude and frequency to cause a disturbance. The drive pinion (19) seated on the hub (7) of the rear wheel can be fastened in the manner known for the conventional sprockets, so that no particular structural adaptations of the hub (7) to the bevel-gear drive are required. The hub (7) of the rear wheel is connected in a tension-resistant manner to the pedal crank (4) via the swinging fork (6) by one or two swinging-fork arms (6a, 6b), so that the rear wheel is guided in an unobstructed manner. <IMAGE>

Abstract: A data-connection device is used to gather information which is stored on corresponding pages of a number of remotely located databases which are all accessible via the public telephone network. The connection device is designed in such a way that it first transmits a call via the telephone network to a first database whose number is stored in an internal memory of the device. The connection device then receives data from this first database which contain a list of telephone numbers which are in each case allocated to a database from which the user can receive information. The connection device is designed in such a way that all the databases whose telephone numbers have been received are called and the data received from the called databases are recorded in the connection device.
