Patent EP-0494400-A2 (EP)
Inventor: BUCK MANFRED DIPL-ING
IPC: B25D17/08
Filed: 1991-12-13
Abstract: In a powered hand tool, in particular a drilling machine or a percussion drill, the tool holder is to be designed to be removable from the spindle. Furthermore, the tool holder is to be easy to lock and unlock and without using further actuating elements. The powered hand tool according to the invention has a tool holder (10) for tools (7) with grooves (33). Engaging in these grooves (33) are locking balls (32) which can be moved into an unlocking position by means of an axially displaceable grip sleeve (27). The grip sleeve (27) at the same time serves to lock and unlock the locking bodies (18) for the mounting of the tool holder (10) on the spindle (3). To this end, the grip sleeve (27), by means of a ring (22) provided with recesses, can be moved rotatably into a position in which the locking bodies (18) escape radially. By means of a torsion spring (37), which at the same time acts as a compression spring, the grip sleeve (27) is held in its position locking both the tool (7) and the tool holder (10).

IPC: H01S3/038
Filed: 1991-01-09
Abstract: A metal vapor laser has a discharge tube (1) with electrodes (2,3) at opposite ends. A power source (5) is electronically connected to the electrodes (2,3) and generates a discharge in a discharge region (4) within the discharge tube (1). The discharge generates laser light which emerges from the tube (1) via windows (12). In order to cool the apparatus, the discharge tube is surrounded by a cooling jacket in the form of a hollow cooling vessel (11). A liquid flows in the cooling vessel (11) and removes heat. The space (10) between the cooling vessel (11) and the discharge tube (1) is evacuated. The cooling vessel (11) is conductive and, since it is connected between one of the electrodes (2) and the power supply (5), its inner and outer walls (11a,11b) provide two potential paths for return current. The fact that the inner and outer walls (11a,11b) have different diameters means that the inductance of the return paths is large. Therefore, the outer wall (11b) has a gap in it filled with insulating material (13). This forms a break in the conductive path from the electrode (2) to the power source (5) through the outer wall (11b), and so reduces the inductance of the return path. Other geometries are also possible in which all but the innermost path are broken by insulating material.

Abstract: A thyristor structure comprises a p⁺-type substrate (21), an n-type base layer (22), a first p-type diffusion region (23) and an n⁺-type diffusion region (25). A MOS structure comprises the base layer (22), first and second p-type diffusion regions (23, 24) and the n⁺-type diffusion region (25). A positive voltage is applied to a gate electrode (27) to form a channel in a portion of the first diffusion region (23) just under the gate electrode (27), so that a cathode electrode (28) supplies carriers to the base layer (22) through the n⁺-type diffusion region (25) and the channel, to turn on the thyristor. A negative voltage is applied to the gate electrode (27) to form a channel in a portion of the base layer (22) just under the gate electrode (27), so that the first p-type diffusion region (23) and the n⁺-type diffusion region (25) are shorted through the channel, the second p-type diffusion region (24) and the cathode electrode (28), to turn off the thyristor.

Abstract: This invention provides a chip-type solid electrolytic capacitor in which a cathode conductive layer is formed on that surface of a cathode layer of a capacitor element which is located opposite to the surface where an anode lead wire is led out, and on a part of a peripheral surface of the cathode layer adjacent to this surface, so that even if the capacitor element is obliquely inserted in a mold for molding a resin shell, the cathode conductive layer will be brought into contact with an inner wall of the mold to modify the inclination of the capacitor element, with the result that when sandblast treatment is performed to roughen the cathode-side peripheral surface of the resin shell, there will not be caused a visual demerit of the cathode layer being exposed from the resin shell.

Abstract: In an article presentation arrangement, such as at a trade fair or in a permanent exhibition, having article samples (2;3;4;5), in particular wall or floor covering tiles (2;3;4;5) which are displayed so as to be accessible to interested parties, the article samples (2;3;4;5) are each provided with a switch in such a way that touching the article initiates the switching operation, and that the latter triggers an actuation of a further arrangement (6) which is visible to interested parties. The switch is preferably a sensor, preferably a capacitive sensor, arranged below the article sample (2;3;4;5). The further arrangement (6) mentioned is, for example, a further article presentation arrangement, for example a display board (9) covered with complementary samples and/or illustrating an example of application or a screen showing an appropriate illustration. The actuation of the further arrangement means the attraction of touching the article and running a hand over it and, with this physical contact, imparts a closer understanding of the article to the interested party and a direct relation to it. The interested party touches the sample and thus, for example in the case of ceramic tiles, perceives slight indentations and elevations in the glaze at colour zone boundaries, etc. <IMAGE>

Abstract: In a transmission system, a solenoid controlled electro-hydraulically actuated creeper mechanism coupler (15) permits selection of very low speeds and provision is made to prevent creeper gear engagement/disengagement, unless controlled by the operator and then only if specified conditions exist. Current flow through the solenoid (83) which actuates the creeper mechanism (70) is monitored at all times to provide a controlled engagement/disengagement of the creeper mechanism (70) in the event the monitored conditions are not within prescribed limits. The current is monitored as the creeper solenoid (83) is energized, while it is energized and when it is not energized so that short or open circuit conditions may be detected before they can cause an unexpected engagement or disengagement of the creeper mechanism (70).
