Title: Manufacture of surface conducting type electron emitting element
Inventor: IWAI HISAMI
IPC: H01J1/316
Filed: 1990-07-03
Abstract: PURPOSE:To form a fine particle film with uniform thickness by making the resistance of the metal fine particle film at least 10 times of the resistance of a final metal fine particle film obtained by applying an organometal compound solution containing an optional content of an organometal to this metal fine particle film and firing it. CONSTITUTION:A metal fine particle film is put in an electron emitting part 3. In this case, wettability between a solution and the surface of a substrate 4 is improved by coating the surface of the substrate 4 with the metal fine particles. At that time, the metal fine particle film formed on the surface is extremely thin and its conductivity is also extremely small, so that the film has infinite resistance as a devices resistance or resistance as high as about at least 10 times of the device' s resistance of the finally obtained fine particle film. Consequently, even if the thickness of the fine particle film is uneven, it does not directly affect on unevenness of the resistance of the finally obtained device. As a result, an organometal solution is applied to the substrate 4 uniformly and a metal fine particle film with uniform thickness and uniform film quality is obtained.

Title: Insert member supporting means in concrete molding form
Inventor: NYURAIIN MASAMI
IPC: E04B1/41
Filed: 1994-07-26
Abstract: PURPOSE:To support an insert member positively even with an error in the fitting hole of the insert member by providing plural claw pieces at an insert core to be inserted into the insert member, and bending the tip side of each claw piece inward. CONSTITUTION:The outer forms 2, 2 of the supporting means 11 of insert members 8, 8 are rotated outward around rotating shafts 6, 6. The insert members 8 are driven in by a hammer to fittingly fix the insert members 8 to claw pieces 22. In this case, a bent part 23 is formed at the tip of each claw piece 22, and the bent part 23 is formed to be narrower toward the tip, so that it is easy to fittingly insert the fit-in part 9 of the insert member 8. Also since the claw piece 22 has elasticity and is inclined slightly outward, the claw piece 22 bends inward when the insert member 8 is fittingly inserted, and the bent part 23 is brought into pressure contact with the fit-in part 9 of the insert member 8. The engaging force of the claw piece 22 thereby works on the fit-in part 9, so that the insert member 8 is positively supported.

Title: Continuous casting mold applied with high frequency oscillation
Inventor: TANAKA SHIYUNICHI
IPC: B22D11/04
Filed: 1980-12-12
Abstract: PURPOSE:To form a uniform powder layer and prevent the generation of longitudinal cracks of an ingot by specifying the surface roughness of the surface of mold copper plates and generating high-frequency oscillations by the friction between the ingot surfaces. CONSTITUTION:Surface roughness of 0.1-1.0mm. pitches and 0.05-0.2mm. surface roughnesses Rmax are applied artificially to the copper plate surfaces of a continuously casting mold in its casting length direction. High-frequency oscillations are generated in said copper plates by the friction between the ingot surfaces. Since additive high-frequency oscillations are applied to powder in addition to an ordinary oscillations, the apparent viscosity of the powder decreases further, and substantially the similar effect to that when powder of low viscosity is used is produced. As a result, the uniform inflow of the powder is realized, the amt. of the powder inflow is increased and the formation of air gaps is reduced.

Abstract: PURPOSE:To provide a porous ceramic material with structural supports which serve the purpose with a good durability by providing in the passageway for combustion gas in the upper part of a furnace a multiplicity of tubes through which a cooling fluid is passed and by fitting on each tube a porous ceramic material in a cylindrical form with a heat-insulating material interposed circumferentially between the tube and the ceramic. CONSTITUTION:When combustibles 3 are burnt on the grate 2 in a furnace 1, unburned ashes 4 together with combustion gas are caught and scattered by a plurality of radiation converters 5 consisting of a porous ceramic material 5a which are disposed zigzag at the exit of the furnace; the unburnt ashes 4 caught by radiation converters 5 at the exit of the furnace because of high temperatures undergo spontaneous combustion where they are caught. The porous ceramic material 5a constituting each radiation converter 5 is supported by a tube 9 for support and a heat-insulating material 11 is filled between the tube 9 and the porous ceramic 5a as a radiation converter 5. The tubes 9 are also cooled from the inner side by boiler water. Since each tube supporting the porous ceramic is thus cooled from the inner side and protected from high-temperature gas on the outer side by a heat insulator thereon, the temperature of the metal forming each tube can be kept low; hence the tubes can be prevented from wear by oxidation and their durability is improved.

IPC: H03L7/08
Filed: 1987-07-14
Abstract: PURPOSE:To obtain stable and correct phase synchronization by providing a control circuit inhibiting the comparison, releasing the inhibition after the stabilization to start the comparison for a period required to make the phase information of a head of a received burst signal stable. CONSTITUTION:When an equalizing signal from a transmission line of the time division control transmission system is given to a control circuit 13, it is differentiated by a differentiation circuit 131, where a pulsative differentiation signal is formed. The differentiation signal is given to a monostable circuit 132 comprising, e.g., a multi-vibrator. A phase comparison circuit 11 is provided with an enable terminal EN and the output of the circuit 132 applies enable control. The enable signal in the equalized input waveform is stopped at a sag generating section and no phase comparison is applied. The enable signal goes to a high level at the portion where the equalizing input signal is made stable to apply the phase comparison. Thus, only the portion where the input signal is made stable is used as a phase information data and stable and correct phase synchronization is obtained.
