Title: Liquid level gauge
Inventor: HIYOUDOU MOTOAKI
IPC: G01F23/32
Filed: 1979-10-25
Abstract: PURPOSE: To eliminate relative positional shift with a side cover and also to ensure indication by an arrangement wherein a projection is provided on a glass for level indication, and the projection and a cut-out window of the side cover are fitted in each other.  
     CONSTITUTION: A cut-out window 13 is formed on a side cover 12 arranged on a side of an oil tank 11 for two-wheeled vehicle, and the cut-out window 13 and a projection 14 of a lens through which to observe a pointer 22 provided at an end of shaft 20 turned by a vertical movement of a float 21 are fitted in each other.

Title: Magneto-optical disk recording medium
Inventor: SAITO KIMIHIRO
IPC: G11B11/10
Filed: 1994-06-20
Abstract: PURPOSE:To obtain a small size and large capacity magneto-optical disk recording medium which can use an existing magneto-optical reproducing pickup by satisfying the predetermined formula with a reciprocal phase difference between returning beams from a land portion and a group portion of a magneto-optical recording medium. CONSTITUTION:A beam focused on a magneto-optical disk is diffracted by the magneto- optical disk and a diffraction pattern can be obtained with a magneto-optical reproducing pickup. The diffraction pattern obtained when a beam indicating the amplitude U (x, y) on the objective lens 12 is diffracted on the surface of disk 11 is indicated by the region where amplitudes of the 1st order diffraction beam are U1a, U1b and the region where amplitude of the 0 order diffraction beam is uo. Here, the amount of light beams of the 0 order diffraction part S0 and the interfering portions S1a, S1b of the 0 order the 1st order diffracting beams is assumed as the phase diffraction lattice and it is then obtained by developing it into the Fourier series. Using this ratio of the amount of light beams, a phase difference phi of the reciprocal light beam paths not generating any crosstalk when a magneto-optical disk is reproduced is calculated as indicated by the formula and this phase difference phi is defined as a phase depth between the land and group portions.

Title: Control device for kerosene combustion device
Inventor: NISHIKAWA TAKASHI
IPC: F24H3/04
Filed: 1993-06-08
Abstract: PURPOSE:To reduce odor when a flame is extinguished under an operation of a control device for an indoor discharged type kerosene combustion device. CONSTITUTION:There are provided a timer 13 energized under a stopping of combustion and for controlling an electrical energization of each of a convection flow fan 7 and a burner fan 6, and a fan control part 14 for applying a brake to the convection flow fan. The timer part operates a fan braking part for the convection flow fan until its first timer part 13a times up and stops an electrical energization for the burner fan. Its second timer part 13b stops an electrical energization for the convection flow fan until its counting is up. In addition, the second timer part is set such that its energization time is extended as its combustion amount during convection flow is reduced. Accordingly, when the combustion is stopped, the convection flow fan is instantly stopped by a brake and a stopping time of the convection flow fan can be extended in response to an amount of combustion just before extinguishing the flame, resulting in that a sufficient odor preventing effect can be attained.

Filed: 1979-10-24
Abstract: PURPOSE:To obtain a semiconductor radiation detector having a higher energy resolving-power and lesser secular change by providing an inorganic surface-protecting film grown at a low temperature on the surface of the semiconductor substrate not covered with a metal electrode. CONSTITUTION:Over the upper and side surfaces of an Si substrate 1, an SiO2 film 7 is deposited by CVD, which is photoetched to remove a portion 8 where an electrode is to be provided.

Abstract: PURPOSE:To manufacture a highly abrasion-resistant seal capable of clear print by preheating resin powder filled in the recessed part for printing of a matrix and at the same time, sintering the powder after precompressing it with a roller or a holding plate, then sintering it temporarily. CONSTITUTION:Thermally plastic resin powder 1 is filled in the recessed part for printing 3 of a seal forming matrix 2, then the powder is preheated and at the same time, it is compressed with a roller or a holding plate 4 and sintered temporarily. Next, continuous foam sheet material 5 of the same quality as the powder 1 is placed over the powder in the matrix 2. After this, the temporarily sintered powder 1 and the sheet material 5 are thermally compressed so that the powder 1 is sintered and the surface between a sinter and the sheet material 5 is fused. Consequently, it is possible to manufacture a qualitatively stable porous seal or its forming matrix accurately and at low cost without requiring technical skill.

Title: Repairing method for mold for continuous casting
Inventor: MINAMI KENJI
IPC: C25D5/28
Filed: 1981-09-01
Abstract: PURPOSE:To improve the adhesive strength of new and old Ni plating surfaces and to prolong the service life of molds for continuous casting made of Ni plating layers on at least inside surfaces in the lower part in the stage of repairing said molds by grinding the surface by leaving the Ni plating layers and further activating the surfaces with a concd. acid then plating the surface freshly with Ni. CONSTITUTION:The Ni plating in the portions in contact with the solidified shell of casting metal in the lower parts of the inside surfaces of cylindrical molds made of Cu or a Cu alloy as molds for continuous casting wears down on account of friction with the solidified shell; therefore a need for repairing the same arises. In such a case, the required parts in the lower parts where the Ni plating layers are thick are ground by leaving the Ni plating layers to expose the fresh Ni plating surface. Said surface is pickled with a strong acid such as concd. nitric acid to activate the ground Ni surface; thereafter an Ni plating layer is formed freshly. Since the surface to be plated is activated, the adhesive power to the fresh Ni plating layer is large, and the decrease in the life of the Ni plating layers on the inside surfaces of the molds for continuous casting on account of abrasion is prevented.

CONSTITUTION:The liquid supplied from a liquid supply pipe 5 passes through a liquid supply passage 3a and a jet orifice 3b to flow down along the atomizing surface 4d of a vibrator horn 4 and is atomized by the ultrasonic vibration from an ultrasonic vibration generating part 2. Since a hollow part 4b is formed to the horn 4, the mass of the horn 4 is reduced and vibration energy necessary for atomizing a liquid substance by the atomizing surface 4d is reduced and, since the atomizing surface 4d has a thin wall thickness, the atomizing surface 4d has flexibility and the end part 4c of the atomizing surface 4d is set so as to become the loop of vibration in order to obtain the max. amplitude and vibration energy is transmitted in the axial and radius directions of the horn 4. The atomizing surface 4d generates flexural oscillation and the liquid substance supplied to the atomizing surface 4d is effectively atomized in large quantities by said flexural oscillation.
