Abstract: A vehicle startup control device for performing prohibition and permission of rotation of a steering shaft in the case where a storage medium is used as an ignition key. A system ECU (19) reads an ID code stored in an IC card (2) through communication means (24) to output a permission code to knob turning prohibiting means (27) when the IC card (2) is judged to be regular, and to stop outputting of the permission code when an ignition knob (23) is operated to a LOCK position in a state where the permission code in being outputted. The knob turning prohibiting means (27) prohibits turning of the ignition knob (23), and permits turning of the ignition knob (23) in a state where the permission code is being inputted. Steering lock unlocking means (28) cancels a turning prohibiting state imposed on a steering shaft by steering locking means (29) in a state where ignition knob (23) is operated to other positions than the LOCK position.

Abstract: A power screw driver (1) includes a clutch mechanism composed of a coiled clutch spring (16) so designed as to entangle a drive shaft member (5) and an output shaft member (7) to connect them together, thereby enabling the drive and output shaft members (5, 7) to rotate in unison. By the use of the coiled clutch spring (16), the clutch engaging operation is achieved smoothly and silently without accompanying impact blow or shock, thereby securing reliable transmission of a torque from the drive shaft member (5) to the output shaft member (7). The coiled clutch spring (16) may be activated only when the drive shaft member (5) is rotating in the forward direction, in which instance a one-way clutch (12) is used to undertake transmission of the torque when the drive shaft member (5) is rotating in the reverse direction. As an alternative, a single clutch spring may be used to undertake transmission of the torque in the forward and reverse rotational directions. Alternatively, two coiled clutch springs each provided for one rotational direction may be used.

Abstract: The high temperature superconductor normal conductor superconductor contact has a metallic layer (1) to connect two superconducting layer regions (2). The contacts act as electrodes and they are separated by a substrate step having a flank (3) on a substrate (4). The flank is covered by an additional layer (5) in such a way that growth of superconducting material on the flank is prevented. The contact is produced by applying the material used to form the additional layer on the step of the substrate in the region of the flank, so that the flank is covered on the additional layer. The material is partially removed from both substrate regions and then the HTSC material is applied to the electrodes and the electrodes connected to each other by applying the metallic layer. LaAlO3 is pref. used as the material to form the additional layer.

Abstract: A method for analyzing impurities within a silicon wafer in a convenient and simple manner with high accuracy and sensitivity. 
     In a first example 1, a silicon wafer is subjected on its surface to a sandblasting process with use of powder of SiO 2  and then to a thermal oxidation process in a dry-oxygen gas atmosphere to easily move impurities present within the silicon wafer into a distorted layer and to form a thermal oxide film and a surface layer of the wafer positioned directly therebelow and containing the distorted layer. The thermal oxide film or the surface layer containing the distorted layer is dissolved with, e.g., a solution of hydrofluoric acid to recover and analyze the dissolved solution. In a comparative example 1, the same processes as in the example 1 are carried out to analyze a predetermined solution, except that the sandblasting process is omitted. In a comparative example 2, the same processing steps as in the example 1 are carried out to analyze a predetermined solution, except that the formation of the thermal oxide film is replaced by a native oxide film without applying any heat. In both of the comparative examples 1 and 2, neither Ni nor Cu is detected; whereas, in the example 1, an Ni content is 100 x 10 10  atoms/cm 2  and a Cu content is 1 x 10 10  atoms/cm 2 .

Abstract: The harvester, designed for mounting on a mobile vehicle, consists of coulters (5) formed from rigid blades which penetrate the soil to below root depth and are vibrated to loosen the roots, and tined wheels (13) in pairs which pick up the roots and pass them on to a cleaner or bin. The tined wheels in each pair are situated symmetrically relative to a vertical plane of symmetry which is in line with that of the coulter pairs, and are angled towards one another at 5 to 20 degrees so they are closest together at the base and rear. The minimal distance between the wheels is such that the roots are held between them without damage, while the maximum distance is such that the roots are released. The wheels penetrate the soil to a depth where their tines are able to pick out the roots, and they are rotated at a speed so that their relative speed at the pick-up point is close to zero.

Abstract: The speed determn. involves a signal guide (4) which forms part of the railway track and is in operative connection with the vehicle (1). In a predetermined transmission position (P1) of the vehicle at least one ultrasonic characterising signal is transmitted to the signal guide (4). In a predetermined reception position (P2) of the vehicle, a given distance s from the transmission position in the drive direction, or in the opposite direction, the characterising signal is detected. The vehicle speed v is calculated according to the equation v=(~Df.c-s)/(~Dtf-~Dt0) when the transmission position is behind the reception position in the driving direction. When the transmission position is in front of the reception position, the speed v is calculated using the equation v=(~Dtf.c+s)/(~Dtf-~Dt0), where c is the propagation speed of the characterising signal, ~Dtf is the cycle time of the signal when the vehicle is moving, and ~Dt0 is the cycle time of the signal when vehicle is at rest.
