Title: Active noise eliminating device for noise in vehicle room
Inventor: HANAWA KAZUHIKO
IPC: G10K11/178
Filed: 1992-02-20
Abstract: PURPOSE:To always obtain an stable noise eliminating effect over the whole area of control frequency even by a compact speaker by providing this active noise eliminating device with a variable amplifier means to be driven so that relation between an input control signal and an output sound pressure signal becomes linear. CONSTITUTION:A variable amplifier circuit 9 is connected between a microprocessor 5 and a D/A converter 4. The circuit 9 incorporates a correction function (amplification factor) z(omega) as plural discrete numeral series. The microprocessor 5 forms a digital control signal 102 by LMS algorithm. The circuit 9 calculates control frequency omega from a crank angle signal 100 and multiplies an amplification factor z(omega) corresponding to the frequency omega by the control signal 102. The multiplied signal is outputted as a speaker driving voltage signal through a D/A converter 4 and a power amplifier 3. Thereby the signal 103 is controlled so that the amplification factor of a sound voltage signal 104 outputted from a speaker 2 with respect to the control signal 102 becomes linear over the whole control frequency.

Abstract: PURPOSE:To expanding a centrifugal oil pressure offsetting function in a hydraulic clutch by storing always predetermined oil in a centrifugal oil pressure chamber between a retainer and a piston. CONSTITUTION:A centrifugal oil pressure chamber 75 is formed between a retainer 72 and a piston 67. Lubricating oil is sent from an oil path 92 of an output shaft 13 to a hydraulic clutch or the like on the output shaft 13 for lubrication and flows into the centrifugal oil pressure chamber 75 of the hydraulic clutch 60 through a check valve 80 to fill said chamber 75. Then, a centrifugal force acts on the pressurized oil in a piston oil pressure chamber 69. When the oil pressure works to press the piston 67 in the press direction, the centrifugal oil pressure of oil in the centrifugal oil pressure chamber 75 works to the piston 67 in the releasing direction so that both are generally balanced to the offset.

Abstract: PURPOSE:To stabilize stored information in a memory cell by a method wherein a voltage which is higher than an external power-supply voltage is generated by using a high-voltage generation circuit installed inside a chip and the voltage is applied to the memory cell. CONSTITUTION:A high-voltage generation circuit HVG is installed on a semiconductor chipoidentical to a static memory; an output voltage which is higher than a power-supply voltage is generated; this output voltage is applied to one or both of holding-current supply terminals HP, LP of a memory cell array CA.

This high voltage is not prescribed by an external power-supply voltage; an arbitrary voltage can be generated according to a constitution of the high-voltage generation circuit. Thereby, it is possible to obtain the static memory which is hardly dependent on an operating condition such as the external power-supply voltage, a temperature or the like and which stores information stably.

Filed: 1984-02-24
Abstract: PURPOSE:To make a ruler stand simply, accurately and vertically, by providing a level in a ruler body. CONSTITUTION:A compressing plate 5 is mounted on a mortar 8, which is placed in a mountain shape on a concrete foundation 7, and a ruler body 1 is made to stand on the plate. The ruler body is surveyed by the periscope of a transit.

IPC: B62D7/14
Filed: 1987-02-17
Abstract: PURPOSE:To reduce the error of a measured value, by reducing the ground contact pressure of the tires of front and rear wheels by raising an automobile body by a lifter. CONSTITUTION:Lifters 48, 49 raising an automobile body to support the same are arranged to the front and rear of a front wheel guide and each of them consists of frames 105 and the cylinder 102 extending up and down fixed to the frames 105 and the rod 101 of the cylinder 102 freely protrudes upward and a head 101a having a groove 101b is mounted to the upper end of the rod 101. Therefore, the rod 101 of the cylinder 102 is extended upward. The groove 101b of the head 101a receives the side sill of the automobile body to raise the same. Therefore, by supporting the automobile body so as to raise the same by the lifter, even when external force in a horizontal direction is applied to the car body, the movement of the automobile body can be prevented. Further, the wt. of the automobile body added to tires can be reduced and the deformation of the tires becomes small and, in measuring a steering angle by a touch type sensor, the error of a measured value can be reduced.

Title: Thin-film temperature sensor
Inventor: OGATA KAZUO
IPC: H01C7/02
Filed: 1988-02-17
Abstract: PURPOSE:To form a thin-film having a value approximating to resistance temperature characteristics(TCR) peculiar to a metal, and to obtain excellent characteristics at low cost by shaping the thin film by the same noble metal as a foundation film on the foundation film formed onto an insulating substrate composed of ceramics, etc., and shaped through heating in atmospheric air. CONSTITUTION:A foundation film 2 consisting of platinum is formed onto an alumina substrate 1 in 4000Angstrom  thickness through a vacuum deposition method. A foundation film acquired by heating the foundation film 2 at a temperature from 750 deg.C to 900 deg.C in atmospheric air takes a partially massive shape and is shaped in insular structure in a plane, but an upper thin-film 3 composed of the same platinum as the foundation film is prepared onto the foundation film, thus easily manufacturing an excellent noble metallic temperature sensor, which has TCR at approximately the same value as a value peculiar to a metal and electrical connection of which is also brought to a continuous state. The temperature sensor is made up of the thin-film, and geometry can be scaled down, thus reducing thermal responsiveness, then forming a high resistance value.

Title: Measurement of anion
Inventor: KITOU AKIRA
IPC: G01N30/06
Filed: 1980-03-17
Abstract: PURPOSE:To determine anion quickly at a high accuracy by removing anion with an excessive metal ion and performing a gaschromatograph of a metal chelate formed with addition of a metal chelate forming agent to the remaining metal ion. CONSTITUTION:A buffer solution is added to a solution of F<-> and then, an excessive known amount of Be<2> solution to the mixture at pH4.9 to form a complex ion between Be<2+> and F<->. An excessive amount (with respect to Be<2+>) of acetyl aceton is added to the solution containing the complex ion to form a chelate of the acetyl aceton. The chelate compound thus formed undergoes a benzene extraction and this volatile chelate compound is determined by a gas chromatography. If previously found, a chelate relationship between the known amount of F<-> and Be<2+> gives the concentration of F<-> in contrast therewith. This method can be applicable where the metal chelate to be formed is so thermally stable that enables the removal of the cation by forming a complex ion or a sediment with a metal.

Title: Bistable semiconductor laser
Inventor: HAMAO NOBORU
IPC: H01S5/042
Filed: 1988-02-16
Abstract: PURPOSE:To reduce the size of an element by providing a laser light reflecting layer of a structure in which two types of semiconductors having different refractive indices are alternately laminated on an upper clad layer or under a lower clad layer, and employing a quantum well structure. CONSTITUTION:The wavelength of the gain peak of the forbidden band width E of a multiplex quantum well layer 5 substantially coincides with that of a semiconductor multilayer film 3 in high reflection, a voltage is applied between a P-type electrode 10 and an n-type electrode 11 to implant carrier to the layer 5, thereby emitting a light of the wavelength of substantially the gain peak. In this case, since an oscillation wavelength is displaced to a long wavelength side, an absorption in high multiplex quantum well refractive index is small. When a reverse voltage is applied between the P-type electrode and the n-type electrode, the absorption peak wavelength due to the exciton of the multiplex quantum well high refractive index layer formed of the film 2 is displaced to a long wavelength side, the absorption of a laser oscillation light is increased, and a bistable operation occurs by the saturable absorption of the exciton. Both a laser light reflecting layer containing the absorption layer and a laser light reflecting mirror are provided thereby to eliminate an absorption region parallel to the layer direction, thereby reducing the element size of a bistable semiconductor laser.
