Title: Telescope using concave spherical reflector as 1st surface
Inventor: KOSHO KAZUO
IPC: G02B23/18
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a telescope which has a large diameter by lowering the cost and increasing the precision by using the concave spherical reflector as the 1st surface of a reflection type telescope, constituting the reflection type telescope on one side of the optical axis so that neither diffraction nor dimming is caused before incident luminance flux parallel to the optical axis reaches the composite focus position, and actualizing an image with high contrast. SOLUTION: The cost is lowered and the precision is increased by using the concave spherical reflector 1 which can be inspected precisely and polished easily. At the focus position 6 of the concave reflector 1 on the optical axis, the focus of a convex oblate spherical reflector 2 is put and thin luminous flux is used as the incident luminous flux parallel to the optical axis 7. The luminous flux is converged on the composite focus position 5 through a concave hyperbolic reflector 3 and a convex hyperbolic reflector 4. Aberrational corrections are made by >=3 reflectors. The sphericity of the 1st surface is applied to constitute the reflection type telescope on only one side of the optical axis 7 and the incident luminous flux parallel to the optical axis 7 is allowed to reach the composite focus position 5 without causing diffraction or dimming. Further, reflection type binoculars can be constituted by arranging two telescopes like this in parallel to each other.

Title: Improved position sensor
Inventor: ZADEUSU SHIYUROIDAA
IPC: G01P3/488
Filed: 1989-08-08
Abstract: PURPOSE: To realize miniaturization and improved reliability and sensitivity by making the width of a permanent magnet to be several times that of an exciter tooth form and making the width of the exciter tooth form larger than that of a sensor area. CONSTITUTION: Relating to a stationary part of a magnetic circuit, a layer 24 of high magnetic permeability magnetic material such as iron which covers the entire bottom surface of a magnet 22 is formed between a sensor element 16 and the permanent magnet 22. To avoid for the layer 24 to form a short circuit with the element 16, an insulation layer 26 is formed between the layer 24 and the element 16. Width W of the magnet 22 equals to the sum of the width of a tooth form 12A and two gaps 12B of an exciter 12. Thus sensitivity is improved. In order to maximize a sensitivity of the magnet 22, the width of element 16 is made narrower than the tooth form 12A. At the facing end parts of the element 16, electrodes 16A and 16B are formed, for connection to an electric circuit. These are metal-plated on the layer.  A magnetic-reluctance material is desirable for the element 16, and it is preferable that a magnetic field is vertically applied on the main surface of sensor area in the element 16.

Title: Cooling method for gas turbine blade
Inventor: NISHIWAKI JINICHI
IPC: F02C7/14
Filed: 1988-08-19
Abstract: PURPOSE:To enable a blade to be efficiently cooled by mixing cooling air with a fine water drop jetted in an atomized state. CONSTITUTION:A ventilating hole 14, communicating with a hollow part 12 in a moving blade 9, is opened to the side surface of a rotor 8. Coating this opening, the rotor 8 mounts to its side surface a ring-shaped guide plate 15, and its inner part provides a ring-shaped feed water pipe 17. Here cooling water, fed from a feed water pipe 18, is blown to the ventilating hole 14 in an atomized state from a nozzle 17a drilled in the feed water pipe 17. In this way, one part of fine drops of water mixes in cooling air of high temperature jetted from a feed air pipe 16, and the water, during its flow mixing, is promptly evaporated decreasing a temperature of air. Further the rest part of the fine drops of water is allowed to flow into the hollow part 12 of the moving blade 9 because of centrifugal force, coming into contact with the internal surface with latent heat of vaporization taken away. Thus, water of large heat capacity and latent heat of vaporization is used serving as a cooling medium in combination with air, so that blade cooling can be improved.

Filed: 1987-08-18
Abstract: PURPOSE:To facilitate manufacture, and to enable highly compact arrangement by composing a magnetic head for recording of at least a heating resistor layer on a magnetic substance and a magnetic substance layer formed onto the heating resistor layer. CONSTITUTION:A magnetic record medium is imparted with a constant writing magnetic field in the direction opposite to previously given remanence by the leakage flux 19 of a writing air gap 20, and the temperature of a section brought into contact with a heating resistor 14 of an upper yoke 18 rises and reluctance is increased and the writing magnetic field in the writing air gap is reduced when the heating resistor 14 is conducted through patterns 15, 16. The upper yoke easily reaches a Curie temperature because it is composed of Mn-Zn ferrite, the heating section of the upper yoke 18 is made equivalent to a non-magnetic substance, and the writing magnetic field generated in the writing air gap can be reduced to substantially zero. Consequently, the writing magnetic field in the writing air gap is controlled by controlling the temperature of a heating element, and a magnetic latent image pattern can be shaped onto a magnetic record medium drum turned adjacent to the writing air gap. Accordingly, a coil is dispensable and simple constitution is acquired, and highly compact and high integration are realized.
