Title: Ceramic injection-molding material
Inventor: KUMAGAI MASARU
IPC: C04B35/00
Filed: 1989-09-29
Abstract: PURPOSE:To improve the dimensional precision, etc., of an injection-molded article by using a powdery org. material having a specified grain diameter at room temp. as the binder at the time of mixing an org. binder into ceramic powder to produce the ceramic injection-molding material. CONSTITUTION:A powdery org. material (e.g. polystyrene resin) having <=1mm grain diameter at room temp. is prepared as an org. binder. The org. binder and ceramic powder (e.g. silicon nitride powder) are mixed to produce a ceramic injection-molding material. As a result, since the powder of the org. binder is compatible with the ceramic powder, both powders are easily and uniformly mixed. Accordingly, when the material is injection-molded, a molded body having uniform density is obtained. Furthermore, when the molded body is sintered, the body is uniformly contracted, and a sintered body having high dimensional precision and sufficient density is obtained.

Inventor: MATSUMOTO MICHIO
IPC: G02B27/00
Filed: 1984-12-03
Abstract: PURPOSE:To attain a sound receiving diaphragm which has a high sensitivity and is superior in impulse resistance by vapor-depositing deposited layers on both faces of a diaphragm substrate consisting of a metallic foil and setting the optical thickness of the deposited layer on the laser light incidence side to a half of the laser wavelength. CONSTITUTION:A diaphragm substrate 10 consisting of a nickel foil having specular surfaces has 2mm diameter phi1 and 2mum thickness t1, and the first and the second deposited layers 11 and 12 consisting of a quartz glass are vapor-deposited to both faces of the substrate 10. The optical thickness off the first deposited layer 11 is set to a half of the wavelength of a laser light source. Though the first reflected light R1 and the second reflected light R2 are generated on the surface of the deposited layer and the boundary surface between the deposited layer and the substrate respectively by an incident light I from the laser light source, synthesized waves of lights R1 and R2 are emphasized because the layer thickness is a half of the wavelength, and the reflection factor is maximized to improve the sensitivity. This diaphragm is made thin because mica is not used, and the resonance frequency is reduced to improve the sensitivity, and the diaphragm is superior in the impulse resistance.

IPC: E02B1/00
Filed: 1985-11-18
Abstract: PURPOSE:To prevent the propagation of wave pressure to the inside of a port for activating the action of automatic depuration by providing a breakwater having a water storage tank opened toward the outside of a port and a water conveyance path opened toward the bottom inside the port. CONSTITUTION:By introducing overflow water 10 of tidal wave 9 outside of a port 3 through a water conveyance path 12 into the port 4 by water head H produced in a water storage tank 11 by means of a breakwater 1, the direct propagation of wave pressure to the inside of the port 4 can be avoided.
