Title: Detector for detecting deteriorated degree of engine oil
Inventor: UCHINO IKUO
IPC: G01N33/30
Filed: 1988-05-31
Abstract: PURPOSE:To determine the acid value of an engine oil, by measuring a quantity of infrared rays with a certain wavelength in a wide range excluding a short wavelength range narrowing a measuring range and a quantity of infrared rays with a specified wavelength within such a specified range that makes acid components in the engine oil easy to absorb. CONSTITUTION:Infrared rays emitted from a light source 1 are condensed with a condenser mirror 2 to irradiate a sample engine oil 4 on a window 3. The infrared rays transmitted through the sample 4 are changed in direction of optical path to a band pass filter 5 with 7.7-9.1mum and a band pass filter 6 with 2.5-9.1mum at each fixed time with an optical path change mirror 9 turned by a motor 10. Infrared rays incident into detectors 7 and 8 passing through the filters 5 and 6 are converted into electrical signals to be inputted separately into a personal computer 14 from an A/D converter 13 through amplifiers 11 and 11a and P-P detection circuits 12 and 12a. Then, an acid value in an engine is measured from an intensity ratio between a quantity of infrared rays with a certain wavelength in a specified range and a quantity of infrared rays with a specified wavelength in a wide range excluding a short wavelength range narrowing a measuring range.

Inventor: ONIZUKA NORIO
IPC: H05B6/76
Filed: 1983-07-21
Abstract: PURPOSE:To positively hold a door-open state and reduce the leakage of micro waves in a door-close state by combining an axially supported arm and an actuating spring. CONSTITUTION:A hinge 4 fixed to a door 3 by means of a screw 11 is axially supported by a hinge shaft 12 to a main body 5, and is rotatable. The other end of the hinge 4 is pressed by a stress F1 of a compression spring 13. Further, since the other end of the compression spring 13 is connected to the main body 5 through a supporting member 14, a force is applied to the door 3 in a direction in which the door 3 is pressed against a front plate 2 of a heating chamber 1, that is, in a direction in which a couple of forces F2 is applied to the door 3, leak radio waves are reduced and the door 3 is closed, the door 3 is stably held at a closed state. In a state where the door 3 is opened, the stress F3 of the compression spring 13 imparts a couple of forces F4 to the door 3 to stably hold the door in a door open state. Thus, a material 9 to be heated and a dish 10 do not hit against an opening and closing mechanism of the door 3, and hence convenience for use is improved.

Abstract: PROBLEM TO BE SOLVED: To obtain a magneto-optical recording medium having a high C/N, excellent durability and high reliability, by forming protective layers of a two-layered structure and forming a first protective layer consisting of a material having a high refractive index on the substrate side of the constitution having a second protective layer having a function to prevent the deterioration of a magnetic layer thereon. SOLUTION: The first protective layer, the second protective layer, the magnetic layer and the upper protective layer are formed in this order on a substrate. The first protective layer is preferably formed of the material having the high refractive index, such as, for example, ZnS or a mixture composed of the ZnS and SiO2 . The refractive index thereof is specified to >=2.1. The second protective layer is preferably formed of the material having a high effect for preventing the migration of S and O to the magnetic layer and the refractive index thereof is specified to <=2.1. Since the first protective layer has the high refractive index, the layer enhances the reflectivity of the magneto-optical recording medium by its enhancement effect. The second protective layer acts to prevent the deterioration of the magnetic layer by reaction, such as oxidation. Then, the thickness of the second protective layer is specified to a value of the extent sufficient for preventing the deterioration of the magnetic layer.

IPC: C08J5/10
Filed: 1986-06-12
Abstract: PURPOSE:To obtain a fiber-reinforced composite material having high strength and excellent formabilty and being inexpensive, by utilizing a blended resin system of a resin having a poor adhesive property with the reinforcing fiber and a resin having a good adhesive property as a matrix resin. CONSTITUTION:A composite material is prepd. by utilizing a blended resin system obtained by blending a resin (A) having a poor adhesive property with the reinforcing fiber and a resin (B) having a good adhesive property with the reinforcing fiber. 2wt% above-described resin (B), pref. >=5wt% thereof are blended. At least one additive selected from among a shrinkage lowering agent, a filler, a pigment and an internal releasing agent can be added to the resin (A). The reason why the properties of this composite material can be improved is estimated that the resin (B) having polar groups in its molecular chain can more dominantly have interaction with the reinforcing fiber than the resin (A) does and therefore there exists a layer being rich in the reinforcing fiber and the matrix resin (B), which gradually decreases in its content.

Title: Displacement-type elvel indicator
Inventor: MURATA EIJI
IPC: G01F23/60
Filed: 1980-09-30
Abstract: PURPOSE:To make the indicator usable for high pressure liquid as well by providing a piezoelectric transducing element between a hermetically-sealed chamber at which a solid float is connected to the center of a diaphragm and another hermetically-sealed chamber having a diaphragm for back pressure. CONSTITUTION:The hermetically-sealed chamber 16 is formed of the diaphragm 15 to which the solid float 24 is connected by a rod 23 and of a housing 10. At the back from the chamber is provided the piezoelectric transducing element 26, which is connected to a lead pin 28. A chamber 19 located on the opposite side of the piezoelectric transducing element 26 is communicated with the hermetically-sealed chamber 18 formed by the diaphragm 17 for back pressure through a passage 22, and non-compressible silicone oil is enclosed in the two sealed chambers. The gravity of the float 24 is adjusted by a spring 25 and thereby a zero position is set. When a level rises, the float 24 presses the diaphragm 15, thereby the pressure in the sealed chamber 16 is increased and, based on the differential pressure between the chamber 16 and the chamber 18, the piezoelectric transducing element 26 detects a signal. Even when vapor pressure rises, the diaphragms 15 and 17 are balanced and thus no output comes out. By this method, the level indicator of high sensitivity and high precision which withstands high pressure liquid can be manufactured.

Abstract: PURPOSE:To increase the mounting density by direct attachment to a printed board by a method wherein the group of electrodes connecting a plurality of semiconductor substrates and element forming surfaces are hermetically sealed from the external space. CONSTITUTION:The element forming surfaces 3a and 3b and the groups of electrodes 2a and 2b are isolated from the external space by hermetic sealing with annular bodies 1a and 1b fixed by bonding to each other.

Besides, this device has a structure of the double-layer lamination of semiconductor substrates; that is, the mounting density is twice as large as the conventional semiconductor device. Consequently, the integration degree can be increased by miniaturization of this device.
