Title: Coating method for rugged surface
Inventor: HATSUTORI NAOKI
IPC: B05D5/06
Filed: 1993-07-30
Abstract: PURPOSE:To make it possible to extremely easily obtain a natural stone-like surface by forming a rugged surface into a state wet with water, applying a coating material dilutable with water thereon and diluting the coating material with the water on the rugged surface, thereby enhancing the flow property thereof and allowing the coating material to flow down to recessed parts. CONSTITUTION:The water 2 is sprayed by a spray gun on the surface of an inorg. plate 1 to make the surface wet with the water over the entire part thereof and the surface is coated with the coating material 3 dilutable with the water by a spray gun immediately thereafter. The coating material 3 is diluted by the water 2 on the surface of the inorg. plate 1, by which the flow property is enhanced and the coating material is allowed to flow down to the recessed part 1A side like arrows. Consequently, the coating material 3 is accumulated in the recessed parts 1A and the coating films which are thick in the recessed parts 1A and thin in the projecting parts 1B are formed. Then, the color of the coating material 3 is dark in the recessed parts 1A and pale in the projecting parts 1B. Such various densities of the colors are particularly significant if the material to be coated is the porous inorg. plate 1.

Title: Noiseproof telephone set
Inventor: OKI YOSHIYUKI
IPC: H04M1/19
Filed: 1992-07-14
Abstract: PURPOSE:To improve speech quality no matter wherever a telephone set may be used by providing a door to open/close a noise insertion hole at a noiseproof telephone set on the front plane of which a directional microphone is provided and on the rear plane of which the noise insertion hole is provided. CONSTITUTION:The noiseproof telephone set is provided with the directional microphone at the front plane and the noise insertion hole 3 at the rear plane, and an input tone from the front plane and the one from the hole 3 function differentially on vibration film. The microphone functions as an ordinary microphone, not as the directional microphone at a place where a small number of noises exists such as a room, etc., since a state where the door 4 of the hole 3 is closed is set, which prevents sensitivity characteristic from being lowered. Also, the door 4 is opened and the noise is fetched from the hole 3 at a place where a large number of noises exists such as outside the room, etc., which displays a noiseproof function. Thereby, it is possible to improve the speech quality in spite of the presence/absence of the noise at the place where the telephone set is used.

Title: Vapor deposition device
Inventor: SHINDOU MASANARI
IPC: C23C14/24
Filed: 1981-12-23
Abstract: PURPOSE:To prevent a shutter material from dispersion (impurity mixture) by a method wherein an open and closed type shutter controlling vapor flow from an evaporation source is made with a high-melting point and good heat conductive material, and a cooling tube is provided in one body on the face of the shutter. CONSTITUTION:A metallic shutter 9 is closed at a vapor deposition preparation stage and is concentratively heated by thermions. Therefore, Si particles scattered by bumping collide with the shutter 9 face. However, as cooling pipe 30 is formed in one body on a thin plate, no source contamination by melting and dropping a shutter material exists and even if the shutter material is exposed at high temperatures during vapor deposition, no melt or deformation of the shutter is recognized or the material is not dispersed. Thus, the film quality of a-Si easily influenced by impurities becomes good. With the aid of this device, Si evaporated from a source 2 at 10<-4> Torrs is deposited as a-Si on a substrate 1, and active gas is simultaneously introduced 6 on and absorbed to the negative potential substrate 1, and H is combined in the deposited a-Si to bury a crystal defect. Then, the obtained film quality is uniform, and both dark resistance and photo sensitivity show good characteristics.

Abstract: PURPOSE:To facilitate the setting of the weight or the like of products to be weighed to specified ranges by sorting the products to be weighed for into a plurality of ranks according to the results of comparison with comparators to apply an incremental reference value to accumulators for totaling rank data. CONSTITUTION:In the taking of product to be weighed out of a container, the rank of the product taken out is displayed in a voice according to the weight of the product.
