Title: Focal distance measuring apparatus
Inventor: ICHIKAWA HAJIME
IPC: G01M11/00
Filed: 1995-02-24
Abstract: PURPOSE: To make it possible to measure the focal distance of a quadratic aspherical surface readily by utilizing the whole surface information of a surface to be tested by holding and adjusting a lens to be tested so that the focal point of the quadratic aspherical surface constituting the lens to be tested agrees with the image-forming point of a condenser lens. CONSTITUTION: When the quadratic aspheric surface of a lens to be tested 1 is the hyperboloid, the plane wave emitted form an interferometer main body 2 is guided to a Fezeau lens 3 and converted into the spherical wave. When the sphere center of the spherical wave, i.e., the image forming point of the lens 3, and the focal point of the hyperboloid are made to agree and alignment is performed, the spherical wave hitting the hyperboloid is converted also into the spherical surface wave. When the spherical wave is orthogonally cast on a returning mirror 4 having the spherical surface, the wave is returned in the reverse direction on the incoming path. Then, the luminous flux, which is reflected form the Fezeau surface in the outward path, and the luminous flux transmitting through the Fezeau surface on the inward path form the interference fringes.  The true hyperboloidal degree obtained in this measurement is the deviation data from the nominal reference surface, and the shape component corresponding to the radius of curvature of the spherical surface is not included.

Title: Sucking and removing method for slag in molten iron treatment
Inventor: MATSUNAGA HISASHI
IPC: C21C7/00
Filed: 1981-03-16
Abstract: PURPOSE:To facilitate slag-off by a suction type slag cleaner for formed slag in divided refining of molten iron by adding the waste slag of a desiliconization (de-Si) treatment at the proper timing of dephosphorization (de-P) or simultaneous desulphurization (de-S) and de-P treatments thereby forming slag. CONSTITUTION:In divided refining of molten iron, the molten iron is subjected to slag-off after a de-Si treatment, in succession to which it is subjected to slag off after a de-P treatment or simultaneous de-S and de-P treatment. The treated slag of the latter has high basicity, low T.Fe and poor fluidity. On the other hand, the amt. of SiO2 in the treated slag of the former is extremely large. Therefore, the waste slag of the de-Si treatment is added to the molten iron at the end period of the de-P treatment of the simultaneous de-S and de-P treatments or upon completion of the treatments or at a proper time from the last period of the treatments till the end of the treatment, whereby the slag is formed. In this way, the slag-off is accomplished with a suction type slag cleaner by reducing the basicity of the slag and improving its fluidity.

Title: Cooking stove
Inventor: SASADA KATSUMI
IPC: F24C15/10
Filed: 1985-02-27
Abstract: PURPOSE:To improve the windshielding of a cooking stove for maintaining normal combustion by constituting the stove with a frame that holds a plurality of claws on which an object to be heated such as a kettle holder is placed and tilting downwards the upper face of the frame from the center side of a kettle holder to outside. CONSTITUTION:The wind 16 blowing toward the combustion section 1 flows into a gap 12. Then the wind 16 flows along the upper side 15 of a frame 10, because it is tilted to the outside, and then the wind 16 flows with its direction changed to the direction toward an object 11 to be heated to become the wind 17. Accordingly the wind 16 that is directed to the combustion section 1 flows to the side of an object 11 to be heated, and the flame of the stove becomes difficult to be fanned. The flame is thus formed normally and it heats a thermo-couple 4 stably. With this constitution the upper face 15 of the kettle holder 8 above the frame 10 works to change the direction of the wind 16 that entered a gap 12, preventing the flame from being fanned by the wind 17, maintaining thereby a stable combustion, and the flame 5 heats the thermocouple stably. The safety valve, therefore, will not shut off the combustion. The ignition of the cooking stove, therefore, will not go off even if wind is blowing while using the cooking stove.

Abstract: PURPOSE:To avoid an eye pattern used for identification from being a form such as an RZ code waveform and to eliminate the deterioration of an S/N by retarding one of branched intermediate frequency signals by one bit in delay detection and comparing the phase after the phase is inverted. CONSTITUTION:When an intermediate frequency signal from a detection circuit 9 is inputted to a delay detection circuit 10, the intermediate frequency signal is divided into two, one is inverted for the phase by a phase inversion circuit 103, the result is retarded by one bit at a delay circuit 101, inputted to a mixer 102, and the other is inputted directly to the mixer 102, the mixer 102 compares the phase of the intermediate frequency signal from the delay circuit 9 with the phase retarded by the delay circuit 101 and inverted by a phase inversion circuit 103 and a base band signal is outputted. In this case, the phase difference with a signal of one preceding bit does not reach an H level on the way of alternate transition from pi to -pi or -pi to pi and the eye pattern used for the identification is not formed to be an RZ code waveform.
