IPC: B28B11/02
Filed: 1992-08-26
Abstract: PURPOSE:To obtain a ceramics molded product having a metal made fitting component of an optional shape by a method wherein a mixture which contains specific contents of powdery glass and a ceramics aggregate as inorganic components is molded, and the metal made fitting component is inserted thereinto to be burned. CONSTITUTION:A mixture which contains 30-80wt.% of powdery glass and 20-60wt.% of a ceramics aggregate as inorganic components is molded. A fitting component may be inserted simultaneously with molding of the mixture and may be inserted into a premolded item which was preliminarily molded. As a metal to be used, its thermal expansion coefficient is preferably 10-20X10<-6>/ deg.C.

Title: Optical information recording/reproducing device
Inventor: TAMIYA KIMINARI
IPC: G11B7/125
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent distortion in a drive current waveform and pseudo light emission by connecting a semiconductor laser drive circuit to be a drive control means with a high frequency oscillation circuit accompanying a semiconductor laser through a conductive fixing means. SOLUTION: In GND connection between the semiconductor laser drive circuit 13 and the high frequency oscillation circuit substrate 15 (semiconductor laser 11), since a screw 18, a chassis 12 and the case of the semiconductor laser 11 are made an electric path, the diameter that a current is able to pass becomes thick, and inductance of wiring that the current flows through the GND side becomes small. In an optical information recording/reproducing device constituted in such a manner, parasitic inductance becomes nearly zero, as small as neglible. The remarkable reduction in the parasitic inductance causes the distortion and the pseudo light emission. By combining the parasitic inductance and parasitic capacity, a caused resonance point is changed to a higher value.

Filed: 1989-09-28
Abstract: PURPOSE:To quickly execute the rotation positioning without increasing the power consumption by constituting the device so that the moment of inertia of a coil and the moment of inertia of a holding body except the coil become roughly equal to each other. CONSTITUTION:When a coil 5 is energized, Lorentz's force by a relation of a current and a magnetic flux is generated in a holding body 2, the holding body 2 is driven to rotate minutely centering around a hinge 3, and a mirror 1 is positioned at a desired angle.

To put it concretely, until a mass state that the moments of inertia are well-balanced is obtained, the coil 5 is wound and installed in excess. In such a way, driving force exceeding conventional driving force is generated without increasing the power consumption, the rotation positioning can quickly be executed.

Title: Detection of acetylene gas dissolved in oil
Inventor: KANBA MASARU
IPC: G01N21/35
Filed: 1987-10-05
Abstract: PURPOSE:To simply and rapidly detect the acetylene gas dissolved in oil, by a method wherein infrared rays having a wavelength of 2.9-3.2mum are transmitted through or reflected from the gas extracted from insulating oil. CONSTITUTION:The insulating oil collected from electric machinery is allowed to pass through a gas extractor A to extract only gas and this gas is recovered in a gas recovery container 1 through a pipe P. Next, the infrared rays having a wavelength of 2.9-3.2mum from a light emitter 2 are allowed to pass through the pervious window 4 among the pervious windows 4, 5 provided to the opposed places of the container 1 to be allowed to be incident to the container to be transmitted through the gas therein. The transmitted infrared rays are transmitted through the pervious window 5 to be received by a light receiver 3. Then, the infrared rays are reacted only with acetylene gas to be absorbed corresponding to the concn. thereof. Therefore, when the intensity of the infrared rays incident to the pervious window 4 is compared and collated with that of the infrared rays transmitted through the pervious window 5 and the difference between both intensities is detected, the concn. of the acetylene gas contained in the transmitted gas can be selectively detected even when other gas is mixed is said gas.

Title: Cosmetic instrument
Inventor: NAKAMURA KENJI
IPC: A45D33/34
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent bacteria contamination or deterioration due to cosmetics by bearing a specified percent by weight of cosmetic material selected from powder, paste, gel or liquid state to the weight of a cylindrical bag. SOLUTION: A cosmetic material is borne or held on the surface of a cylindrical bag 1 by coating or impregnation. The application amont or the impregnation amount of the cosmetic material ranges from 50 to 500 wt.% of the cylindrical bag weight. In this case, a plastic film is suitably integrated with the inner surface of a sheath bag 1, thereby preventing the fingers from being stained when cosmetics are applied. The germ-free cylindrical bag bearing germ-free cosmetics is air-tightly packaged in one or plural units for use to dispense with a germicide or an antibacterial agent affecting adversely the human body such as paravane or the like. The germfree cosmetic material itself is thus borne on a germfree applicator and packed in each unit for use.  Accordingly, it is not necessary to worry about bacterial contamination and damage from chemicals to deterioration and discoloration, and an application tool of high quality stability and simply usable can be obtained.
