Patent EP-0186316-A1 (EP)
Inventor: WALLACE WILLIAM KEITH
IPC: B25B23/145
Filed: 1985-11-26
Abstract: A rotary power tool is operated by an air motor or electric motor drive designed to produce an adjustable output torque. The driven impulse member (40) has a cam surface (64) driven by a driver (66) which is axially or radially movable in a driving cage (32) mechanism whereby the torque developed by the power tool cyclically varies be- tweeen zero and a predetermined adjustable maximum quantity. Due to the cyclical variation in the torque developed there is no. impact component of the torque delivered and therefore the tightening torque will not increase as the number of torque cycles increases (Fig. 5).

Abstract: The invention relates to a process for producing a spherical grain shape in fine grain toners. The toners are of the type used in electrophotography for developing latent charge images. The treatment of the toner takes place in a material bed which is fluidized by gas streams which are directed against one another. In this manner the grains are subjected to a multitude of reciprocal collisions and friction stress. The intensity of the collisions and frictional stress are adjusted through selection of the operating pressure, velocity, direction and temperature of the gas streams. Thus the grains undergo permanent deformation. A classifier to separate out the super-fine portion resulting from abrasion.

Abstract: Apparatus for dispensing a length of sheet material from a roll (33) eg of paper towels is actuated in response to the proximity of a portion of a band of a user to the apparatus without the hand of a user contacting the apparatus. The dispensing is done by an electrical motor (57) operating for a predetermined time and which can be powered by batteries (61). An LED (50) transmits pulses of light which are sensed by a sensor (52) arranged on the opposite side of a hand receiving open cavity (46q). When the pulses of light are interrupted by the hand a capacitor (88) is enabled to actuate the dispensing mechanism. The housing (31) of the apparatus has a modular frame (46) having a first compartment (46b) for the means for advancing the sheet material and a second compartment (46f) for the means for activating the advancing means. The dispensing apparatus can include means for storing energy (eg., 61) for energizing the advancing means in response to the withdrawal of sheet material from the dispensing apparatus by a user.

Abstract: Un dispositif pour bains de soleil comprend un canapé pour une personne qui doit recevoir un traitement aux rayons solaires, et un dais (1a, 1b, 1c, 1d, 1e et 1f) qui surmonte le canapé et comprend des éléments de rayonnement solaire (2a, 2b, 2d, 2c, 2e et 2f). Le dais est maintenu dans la position correcte par un support. Il est impossible d'utiliser un dispositif pour bains de soleil de ce type dans un petit appartement. L'objet de l'invention est la création d'un dispositif pour bains de soleil qui demande un espace minimum lorsqu'il n'est pas utilisé, et qui puisse être rangé dans l'espace étroit situé derrière un canapé. A cet effet, un assemblage étroit de rails de guidage (5a et 5b) s'étend tout d'abord verticalement derrière un canapé à partir d'un plateau (12) posé sur le parquet et situé surtout sous le canapé, et ensuite l'assemblage s'étend au-dessus du canapé, cette partie non-verticale (7a et 7b) de l'assemblage de rails de guidage (5a et 5b) étant amovible. Le dais (1a, 1b, 1c, 1d, 1e et 1f) peut se déplacer le long des rails de guidage (5a et 5b) depuis une position horizontale jusqu'à une position verticale. Comme il est divisé en une pluralité d'éléments longitudinaux (1a, 1b, 1c, 1d, 1e et 1f) articulés entre eux, le dais fonctionne comme un volet roulant dans lequel des organes (4a) situés sur chaque élément glissent sur les rails de guidage (5a et 5b).

Abstract: A transistor of MIS type multigate structure is used in a ROM (read only memory) by disposing a threshold voltage controlling region under each gate and making use of the difference in the threshold voltage at the gates. The threshold voltage controlling region of one of the gate structures in such multigate structure is obtained by etching the semiconductor substrate (11), using the first gate structural part (14, 15) as the mask, to form a specified impurity diffusion layer (18) in the etched surface and by forming a second gate structural part (19, 20) thereon. Said first and second gate structural parts may be formed by self-matching method, and their positioning may be easy, so that the response to downsizing of parts may be improved, and a structure suited to higher degree of integration will be realized.
