Title: Heat exchanger
Inventor: MURATA RIYOUHEI
IPC: F28D1/06
Filed: 1982-03-05
Abstract: PURPOSE:To increase the contact area of a medium to be heated and a heating tube through which a heating medium is passed, by shaping the heater tube disposed in a tank of a heat exchanger in a helical form having turns the diameter of which is changed. CONSTITUTION:A heater tube 16 having one end 16a connected to a manifold 14 is shaped in a helical form, and the other end 16b of the heating tube 16 is connected to a header 20 at a position located lower than the position where said one end 16a is connected to the manifold 14. Between the upper plane where said one end 16a of the heating tube 16 is located and the lower plane where said other end 16b is located, the diameter of turns of the heating tube 16 is decreased gradually downward with respect to the axis of a tank 12. With such an arrangement, heating medium supplied from a supply source into the manifold 14 exchanges heat with water 22 through the wall of the heating tube 16 while passing through the heating tube 16. Here, since the heating tube 16 is shaped in a helical form having diameter-changed turns as described above, it is enabled to increase the contact area of water 22 and the heating tube 16.

Title: Hydraulic power steering device
Inventor: HOGO YASUHIRO
IPC: B62D6/02
Filed: 1993-01-29
Abstract: PURPOSE:To decrease a fluctuation of steering assist force by displacing a mover in accordance with changing electromagnetic force corresponding to an operational condition and changing a hydraulic pressure in the upstream of a throttle part of this electromagnetic force, and setting a direction of the displacement in accordance with changing the hydraulic pressure to a direction of negating changing this hydraulic pressure. CONSTITUTION:Electromagnetic force of a solenoid 61 is increased according to decreasing a car speed, and an opening of a throttle part 67 is decreased to increase a pressure in the upstream of this throttle part 67. The first valve side recessed part 50 is displaced upward relating to the second valve side recessed part 51, and an opening of throttle parts A, B, C, D in an intervalve flow path 27 under fixed steering resistance is decreased. Thus at low speed running time, because of large ratio of increasing a hydraulic pressure for generating steering assist force with a small opening of the intervalve flow path 27 even by a small relative rotational amount between the first/second valves 31, 32 with small steering input torque, high responsiveness of steering can be satisfied.

Abstract: PURPOSE:To suppose the deterioration of graininess due to storage over a long period of time by regulating the rise of the min. optical density of each of at least two color-sensitive layers to a specified value or below in the case where development is carried out after storage under specified conditions for 7 days. CONSTITUTION:The rise of the min. optical density of each of at least two color-sensitive layers is regulated to <=0.08 in the case where development is carried out after storage at 55 deg.C and 20% relative humidity for 7 days. In order to regulate the rise of the min. optical density due to storage, silver halide produced under conditions which inhibit fog is used and a substance adsorptive to silver halide particles and other than gelatin is added at the time of preparing a silver halide emulsion. Consequently, superior reciprocity law failure characteristics at a high illuminance are ensured and the deterioration of graininess due to storage over a long period of time is suppressed.

Title: Rotary transformer
Inventor: OOMORI TAKASHI
IPC: H01F38/18
Filed: 1982-03-04
Abstract: PURPOSE:To enable miniaturization, and to reduce signal deterioration, by a method wherein two rotary side coils are wound on a split core which is magnetically separated for the time-division signal transmission. CONSTITUTION:A rotary side core 9 is quartered by 90 deg.. Circular grooves 11A and 11B are formed on both sides of the aplit core 10A and 10B, respectively, and coils 12A and 1''B of the rotary side are wound along the grooves, respectively. A fixed side core 16 is equi-split by 180 deg.. A circular groove 19 is also formed on both sides of one of the split core 17, and a fixed side coil 20 is wound along the goove 19. The coil 20 serves for both two channel coils of the rotary side 12A and 12B. Accordingly, employing only one groove for coil winding, the two coils of the rotary side can be separated magnetically, and signal deterioration can be reduced. Further, as the groove for coil winding is only one, the radius of the core may be made smaller, thus the whole body may be made smaller.

Abstract: PURPOSE: To obtain a high molecular piezoelectric material with high piezoelectric rate at a drawing magnification of different polarity by a method wherein the polarity of piezoelectric rate is inverted with the drawing direction and its rectangular direction through subjecting a copolymer of vinylidene fluoride and ethylene trifluoride to drawing polarization.  
     CONSTITUTION: A copolymer with composition of ethylene trifuloride and vinylidene fluoride at a given weight percentage is formed to a film through hot press, and the film is drawn to a given thickness at a given magnification by changing the drawing temperature to a given temperature. Then, the film is metallized with Al, and after it is subjected to a polarizing treatment for a given period of time under conditions of given temperature and given voltage, it is allowed to stand for a given period of time. After that, piezoelectric rate in the drawing direction and rectangular direction is inverted, and the piezoelectric rate in the drawing direction is maximized in the neighborhood of drawing. By using the high molecular piezoelectric material which indicates this characteristic as a sensor, a polarity of the output potential with an input from the drawing direction and that from the rectangular direction is inverted, and thus a single sensor is ready for distinguishing the input accordingly.

Abstract: PURPOSE: To manufacture an alloy magnetic powder composed mainly of Fe and Pd, having high saturated magnetizing and coercive force, by the procedure in which a needlelike iron oxide or hydrated iron oxide powder is coated with Pd (OH) 2  and then dehydrated and reduced.  
     CONSTITUTION: Pd(OH) 2  is adsorbed in the surface of a needlelike iron oxide, e.g., gamma-Fe 2 O 4 , etc., or a needlelike hydrated iron oxide, e.g., goethite, etc., and then subjected to a dehydrating heat treatment, followed by a reductive treatment and then annealing treatment by which Fe and Pd are made to mutually diffuse into each other to form an uniform Fe-Pd phase, resulting in a high coercive force Hc. Because the coercive force Hc and the saturated magnetization of the alloy magnetic powder obtained by this method are sufficiently high, this magnetic powder is suitable as magnetic material for magnetic recording mediums having high density and high output.
