Patent EP-0337723-A1 (EP)
Inventor: TABATA KAZUMASA C O KOYO SEIKO
IPC: B62D5/083
Filed: 1989-04-11
Abstract: A hydraulic pressure control valve of the present in­vention applied in hydraulic power steering includes a cyl­indrical casing (1) whose plural first grooves disposed on its circumferential surface at stated intervals are brought in communication with different destinations of pressure oil, and a valve body (2) which is inserted rotatably into the casing and whose second grooves of the same number as the first grooves, disposed on its peripheral surface at stated inter­vals are brought in communication alternately with a high pressure source and a low pressure source, and a portion thereof is disconnected with the low pressure source. At corners on the casing opposing each other across the com­municating portions on both sides of the disconnected por­tion of the valve body, notches are formed in such a shape that, until the relative angular displacement between the valve body and casing reaches the predetermined magnitude, variations of communicating areas produced between the first and second grooves by the relative angular displacement is substantially not produced. In the hydraulic pressure con­trol valve, the first groove of the valve body interposed between the notches is not in communication with the low pressure source, and the pressured oil which flows in through one communicating portion of this portion is intro­duced into the groove of the adjacent casing through the   other communicating portion without flowing back to the low pressure source, so that flowing noises of pressured oil produced when the relative displacement is produced between the valve body and casing can be reduced sharply.

Abstract: A time division multiplexed (TDM) hydraulic control system having a plurality of channels (12,14,16) each channel having a servo actuator (72,74,76) is disclosed. Electrical demand signals are arranged in TDM sequence and applied to a single multiplexed pilot valve (28) so that the pilot valve produces a plurality of hydraulic signals. Commutator means (31) are associated with the pilot valve for distributing the hydraulic signals to the associated channels (12,14,16). In order to achieve useful output flow rates in the channels (12,14,16), each channel includes a second stage valve (42,44,46) which integrates the hydraulic signals for its channel to produce an output flow rate which is a function of the integrated signal. The flow rates are continuously produced (as compared to the multiplexed output signals) and are coupled to the actuators (72,74,76) in the channels for controllably adjusting the position thereof. Feedback means (82,84,86) associated with the actuators (72,74,76) includes rate feedback for stabilizing the multiplexed control loops.

Abstract: The developer composition comprises an aromatic compound having hydroxyl groups in the  meta -configuration, typically at the 1- and 3-positions thereof, or a salt thereof, and free of any electron attractive group, together with an alkaline agent and water. The developer composition can effectively be used in a method for making lithographic printing plates which comprises the steps of: exposing to light a presensitized plate precursor for a lithographic printing plate provided with a water-insoluble image-forming layer formed on a substrate and developing the plate to remove non-image portions. Lithographic printing plates manufactured according to the method provide printed matter free of background contamination. If the pH value of the developer is controlled to not less than 12, both positive-working and negative-working presensitized plates can be treated therewith. Moreover the working efficiency is greatly improved since it removes the need to provide two kinds of developer compositions and two kinds of developing machines. This initial cost can be saved and the space for installing such machines are also greatly reduced.

Abstract: An optical information reading apparatus comprises an optical integration circuit type pickup (A) in which an optical waveguide (4) for guiding light and a condensing coupler (3) for condensing the guided light propagating within the optical waveguide are formed on an optical integration circuit substrate (1). Sub-couplers (100,102) radiate a part of the injected light on the surface of an information recording medium in the vicinity of a light spot (8) formed by the optical pickup. Subsidiary light detection elements (101a,101b,103a,103b) receive reflection light of the light radiated from the sub-couplers reflected from the information recording medium surface. The sub-­couplers and the subsidiary light detection elements are formed integrally with the optical pickup on the optical integration circuit substrate (1). Thereby the detection error can be reduced and, as it is not necessary to use attachment parts, therefore the apparatus can be integrated to thereby make it possible to minimize its size.

Title: Condensateur ceramique semi-conducteur isole a coupure de grain de type lamine et son procede de production
Inventor: UENO IWAO
IPC: H01G4/12
Filed: 1990-02-16
Abstract: Un condensateur céramique semi-conducteur isolé à coupure de grain de type laminé sert de condensateur d'absorption de bruits de faible tension ou de haute fréquence et sert de varistor lorsqu'on y applique une tension élevée telle qu'une impulsion ou de l'électricité statique. Son principal composant est SrTiO3, ce qui permet de cuire simultanément le matériau du condensateur céramique et le matériau de l'électrode interne. L'invention concerne également un procédé de production du condensateur. La raison pour laquelle la cuisson simultanée des matériaux est devenue possible est le fait que l'on ajoute au SrTiO3 des composants semi-conducteurs avec un excédent de Ti, et que l'on ajoute en outre du Mn et du Si, qui sont tous les deux convertibles en MnO2 et en SiO2 pendant la cuisson. Bien qu'on ait appliqué un procédé classique de diffusion en surface d'oxydes métalliques, celui-ci peut être omis. On obtient aisément un condensateur semi-conducteur isolé à coupure de grain uniquement par réoxydation. Etant donné que le produit moulé est calciné après son laminage à l'avance dans l'air, le condensateur céramique laminé à fonction de varistor permet de minimiser l'occurrence de problèmes tels que la rupture de l'électrode interne, le délaminage, des fissures, la réduction de la densité de frittage et des structures hétérogènes dans le corps fritté. Le condensateur a des propriétés électriques considérablement améliorées, telles que la capacité, l'indice alpha de non-linéarité de tension et la tension de varistor, ainsi qu'une fiabilité améliorée. Par rapport à ces deux points, l'invention a des avantages remarquables en ce qui concerne la composition du matériau et son procédé de fabrication.
