Patent EP-0287940-A1 (EP)
Inventor: SUGIURA HIROYUKI C O DIESEL KI
IPC: F25B49/02
Filed: 1988-04-13
Abstract: A variable capacity compressor (1) for use in a heat-exchange circuit. A pressure responsive valve (29) is provided in a communication passageway extending between a low pressure chamber (34) and a pressure controlled chamber. The pressure responsive valve is operative in response to pressure within the low pressure chamber (34) for opening and closing the communication passageway to control pressure within the pressure controlled chamber, thereby varying the capacity of the compressor in such a manner as to reduce the capacity when the pressure within the low pressure chamber decreases to a level lower than a predetermined value. An electrically operated control device (30) is operative in response to pressure or temperature of refrigerant gas in an evaporator of the heat-exchange circuit for maintaining the capacity large independently of operation of the pressure responsive valve, even if the pressure within the low pressure chamber decreases to a level lower than the predetermined value.

Abstract: A piston pump with a working piston (3) for compressing fluids and gases has a device for filling and emptying a working chamber (12). Two or more seals (9, 10) are arranged in succession between the working piston (3) and the cylinder wall. Located in the interstices between each two adjacent seals (9, 10) are annular pressure chambers (11), to which auxiliary hydraulic circuits are assigned. The pressure is reduced in steps or stages by way of the seals (9, 10) arranged in succession. In the case of a hydraulic medium with no lubricating action the required lubricating effect on the seals is achieved by a suitable oil supply. <IMAGE>

Abstract: A blade angle control device for an axial flow fan, the blades (7) of which are adjustable between two extreme positions during operation, comprises a control ring (9) coaxial with the hub (1) of the fan impeller and connected through links (15), with control arms of each blade. 
     In an initial position, where the blades are in one extreme position, the control ring (9) abuts on one face of the hub (1) which is located in a radial plane of the impeller. A pneumatically operated piston device (11,12,14) connected to the control ring (9) and locat­ed radially within the ring may shift the ring axially from the initial position towards a position in which the blades are in their other extreme position. 
     A plurality of precompressed springs are located in tubes (18) extending through bores in the hub ra­dially outside the piston device. Each spring surrounds a pin (19) connected to the control ring and biases the rin towards its initial position. 
     The mass of the impeller is concentrated on a short axial length so that the impeller can be secured directly to the shaft (2) of a drive motor. By varying the number springs and possibly their length and pre­compression the total spring force, preload and spring rate of the control device can be adapted to any need.

Abstract: In order to transmit high-definition television programmes over a transmission channel of lower capacity than the spectral band of the picture signal, there is performed, on transmission, a sub-sampling of the picture distributing the spatial information over n successive frames (n being an integer greater than 1) and, on reception, an interpolation filtering. In order to improve the compatible picture received, the high-definition coded picture is subjected to a temporal attenuation filtering of the energy in the region close to fo/n (fo being the picture frequency) after high-definition decoding and before transmission, and to a temporal accentuation filtering corresponding to the attenuation before high-definition decoding on reception.

Title: Method of partitioning the internal space of a hollow cylindrical member
Inventor: HONDA SYUNITI
IPC: B23P11/00
Filed: 1989-07-31
Abstract: The internal space of a thin-walled cylindrical member is partitioned by securing a thin-­walled partition member in place within the cylindrical member by means of calking. 
     The method comprises the steps of: 
inserting a circular thin plate partition member (6) into the hollow cylindrical member (1), the partition member having a circular plate portion (7) and a rim portion (8) axially extending from one side of the periphery of the circular plate portion, the hollow cylindrical member being formed therein with a space portion (2) of larger diameter and a space portion (3) of smaller diameter, the portion of larger diameter being formed at its end adjacent to the portion of smaller diameter with an annular groove (4); placing the partition member on a shoulder face (5) formed between the two space portions so that the circular plate portion comes in contact with the shoulder face; and applying by means of a push rod (9) with a press portion (10) an axial force to the end face of the rim portion of the partition member to cause the rim portion to deform (Fig. 4) so that a portion of the rim portion penetrates into the annular groove. The partition member is thereby tightly secured by means of calking to the annular groove and consequently to the hollow cylindrical member, without applying a substantial radial force to the wall of the cylind­rical member. The cylindrical member may serve as a piston or in a hydraulic valve lash adjuster.

Abstract: Le dispositif d'échange thermique (10) comprend au moins un élément à cylindre interne (18) et au moins un élément à cylindre externe, définissant entre eux un ou plusieurs espaces annulaires à travers lesquels un milieu d'échange thermique pressurisé est amené de force à s'écouler. Un ou plusieurs éléments rotatifs (28), sur lequel sont formées plusieres parties saillantes en forme de dents (32, 34) définissant des rainures longitudinales continues ou segmentées (36), sont disposés à l'intérieur des espaces annulaires. Le milieu d'échange thermique pressurisé imprime une force angulaire à l'élément rotatif, ce qui amène le milieu à s'écouler très rapidement avec un vecteur de tourbillonnement élevé à l'intérieur des rainures et également entre les extrémités distales (84) des éléments en forme de dents et la surface circonférentielle adjacente (82) des éléments à cylindre interne (18) et à cylindre externe (12). Une force angulaire peut être imprimée à l'élément ou aux éléments rotatif(s) par des sources d'énergie extérieures, comme supplément à l'écoulement du milieu d'échange thermique pressurisé. L'écoulement rapide et le vecteur de tourbillonnement de milieu d'échange thermique produisent une augmentation au moins dix fois plus grande des gradients ou des coefficients de transfert thermique.

Abstract: Dispositif pour mesurer les températures et vitesses de pièces en rotation, notamment d'arbres de machines électriques comme des moteurs et des générateurs. On effectue sur un arbre (4) des repères (2) qui se modifient en fonction de la température. Un détecteur fixe (1) réagit à la modification des repères et délivre une impulsion de tension permettant de dériver la température et la vitesse de rotation. Ces repères peuvent être constitués de bandes de liquide (2) ou de ferrite (13) qui présentent à une température donnée un changement de couleur ou une variation de leur magnétisme (par ex. point de Curie). Il est également proposé de monter un détecteur simple (5, 12) qui modifie sa position ou sa sensibilité de mesurage en fonction de la température et qui, à partir de la disposition de repères géométriques fixes sur l'arbre, dérive la température et la vitesse de ce dernier. Les mesures s'effectuent sans contact et ne nécessitent qu'un détecteur.

The twist angle, And and incident polarizing angle are so set that the plane of polarization of the outgoing light is 90 degrees different from that of the incident light (preferably, 0.33λ ≤ Δnd 0.4X when the twist angle is 63° and 0.95λ ≦ Δnd ≦ 1.15λ (unit in µm) when the twist angle is 193°, and the axial direction of the polarized angle and the direction of the liquid crystal molecules are brought into agreement with each other). Since it is allowed to set a large value And, thickness of the liquid crystal layer can be increased, an increased margin is obtained from the standpoint of production, the exit light is linearly polarized and permits reduced amounts of optical loss to take place compared with those which emits ovally polarized light. By setting optimum twist conditions, furthermore, the liquid crystal electro-optical device exhibits sharp electro-optical characteristics with respect to the electric field and produces display maintaining a high contrast.
