Title: Magnet for mri
Inventor: TAKAHASHI RYOICHI
IPC: A61B10/00
Filed: 1986-09-02
Abstract: PURPOSE:To provide a magnet for a MRI device so that the number of its parts and the manufacturing cost are small, by forming holes, through which bolts for coil position supporting and a jig for bolt rotation are inserted, in an outer shell which surrounds a plurality of coils generating magnetostatic fields. CONSTITUTION:This device is composed of an outer shell 30, which surrounds a plurality of coils 13 generating magnetostatic fields and has holes 31 for jig insertion, and a plurality of bolts which are mounted rotatable on the outer shell 30 and brought in contact with the coils 13. The jig 50 is composed of gears 51, 52, 53 and a chassis 54, and a hole 53a engaging with a bolt head part 41 is formed on an axis end of the output gear 53. When the jig 50 is penetrated through the hole of the outer shell 30 and the hole 53a is made to engage with the bolt head part 41 and the gear 51 is rotated, the rotation causes rotation of the bolts in contact with the coils. Therefore, the bolts are moved in the axis direction so that the coils 13 are pushed to adjust the coil position. Because a plurality of coils, bolts, and the outer shell are all required, the number of parts becomes small.

Title: Heat exchanger for combustion type heater
Inventor: IDA HIROYUKI
IPC: F24H9/00
Filed: 1989-08-08
Abstract: PURPOSE:To prevent an end part on a combustion gas inlet side of an inner drum from being heated to a high temperature by locating tips on the combustion gas inlet side of a heat-receiving fins at the further downstream position in the combustion gas passage than an outlet open end of a combustion tube. CONSTITUTION:Combustion gas coming from an outlet open end of a combustion tube 14 strikes against a guide plate 16a of a blind material 16 and is directed toward a combustion gas passage A, however, tips on the combustion gas inlet side of heat-receiving fins 17 are located at the further downstream position in the combustion gas passage A than the outlet open end 14a of the combustion tube 14 so that the combustion gas, which shifts the flow direction as it strikes against the guide plate 16a, flows into the combustion gas passage A and then strikes against the heat-receiving fins 17. Therefore, an end 80a on the combustion gas inlet side of an inner drum 80, where no heat-receiving fin 17 is provided, receives less heat from the combustion gas, so that said end 80a is prevented from being heated to a high temperature.

Title: Heat exchanger
Inventor: MAEKAWA YOSHIHIRO
IPC: F28F1/40
Filed: 1982-11-22
Abstract: PURPOSE:To improve heat transmitting efficiency by a simple mechanism by a method wherein a coil is attached to the inside and/or the outside of a heat transfer tube so as to be contacted with the wall of the tube. CONSTITUTION:In the double tube type heat exchanger 1A, consisting of the heat transfer tube 2 and a jacket 3 enclosing the tube 2, the coil 5A is attached to the inside of the heat transfer tube so as to be contacted with the tube wall 21 of the tube 2. According to this method, a heat transfer area is increased and the flow of fluid is disturbed since the fluid flowing in the tube collides against the coil at the tube wall. As a result, the resistance of a boundary film is broken forcibly and a heat transfer coefficient may be increased even if the flow speed of the fluid is comparatively low.

Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To effectively carry out measurement of characteristics of an optical path by setting an attenuation of light receiving attenuator in a photo-pulse testing apparatus automatically and at a high speed. SOLUTION: A photo-pulse testing apparatus comprehends a control command sent out of a controlling apparatus by a CPU 11 and automatically adjusts the attenuation of a light receiving attenuator 19. At first, the attenuation of the light receiving attenuator 19 is so adjusted as to keep the backscattering level in a part near an optical path within a prescribed range of light receiving level. In the case where the light receiving level in the far end direction is higher than the backscattering level in a near end part, the attenuation of the light receiving attenuator 19 is increased by a prescribed value by pulse width.  Fresnel reflection higher than the backscattering level in the near end part and in the farthest end direction is made to be an optical path terminal and the attenuation of the light receiving attenuator 19 is so adjusted as to make the light receiving level in the near end direction from the optical path terminal not exceed a prescribed light receiving level and then measurement of characteristics of the optical path is started.
