Title: Optical fiber gyroscope
Inventor: TAI SHIYUUICHI
IPC: H01S3/083
Filed: 1982-10-04
Abstract: PURPOSE:To obtain an output signal in AC format and to imprvoe precision by applying phase biases which vary in a sine shape to light beams which are projected from an optical fiber loop after propagating therein clockwise and counterclockwise. CONSTITUTION:The plane of polarization of the light beams which propagate in the optical fiber loop 3 clockwise and counterclockwise are at right angles to each other and have a phase difference DELTAtheta proportional to a rotating speed owing to Sagnac effect when projected from the loop. Light passed through a phase modulator 8 is split by a beam splitter 2 into two linear polarized light components. An AC signal superposed upon a driving signal to the phase modulator 8 is for applying an AC phase bias asinomegat, and the supplied signal light is converted by an analyzer 13 into light intensity I, which is obtained by imposing amplitude modulation upon sinomegat by DELTAtheta. A divider 11 divides the output of an amplifier 6c by the output of an adder 6b and inputs the result to a peak detector 14 to obtain a DC signal proportional to the phase difference DELTAtheta.

Title: Self-propelled root vegetable harvester
Inventor: YOSHIDA MICHIICHI
IPC: A01D25/00
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent the simultaneous drawing-in of a mulching film when leaves of root vegetables are pulled out in a self-propelled root-vegetable harvester which digs up root vegetables from the soil covered by mulching film, and pulls out and transfers them to store in a storage container. SOLUTION: In a work of the digging-up and pulling-out of root vegetables cultured on a ridge covered with a mulching film 70, when the root vegetables are pulled out at the starting end of a pulling-out conveyor, the mulching film is brought up together with the root vegetables, and even the mulching film is occasionally drawn into the conveyor. In order to prevent such a trouble, mulching film-pressing rollers are placed below the front end of the pulling-out conveyor. The mulching film-pressing rollers are constructed in such a manner that, when leaf parts of the root vegetables are clamped at the front end of the pulling-out conveyor and sent toward the back and upper direction, only the root vegetables are sent back by the pulling-out conveyor, and a deviser 30 for raising up the leaf part is placed at the front end of the pulling out conveyor.

Title: Stabilized power source circuit
Inventor: SUZUKI KENJI
IPC: G05F1/56
Filed: 1990-06-29
Abstract: PURPOSE:To reduce the fluctuation of a limiting current caused by the change of the working temperature by connecting a temperature compensating circuit provided for an overcurrent protecting circuit to this circuit through the reference voltage. CONSTITUTION:A limiting current ID1 is secured. The potential VP is defined at a point P as VP=Vref-VBE1+VBE13, where VBE1 shows the base-emitter voltage of a transistor Tr1 and VBE1=VBE13 is satisfied. Therefore VP=Vref. Then ID1XRO1=Vref is satisfied in an ON state of a Tr13. Thus the current ID1 is shown by an equation I. In this equation I, the temperature coefficient of the reference voltage Vref is equal to about +20PPM/ deg.C with the temperature coefficient of an emitter diffused resistance R13 set at about -200PPM/ deg.C respectively. Therefore the temperature coefficient of the current ID1 is equal to about -200PPM/ deg.C as long as the temperature coefficient of the Vref is neglected. Thus the temperature coefficient is reduced by 1/2.5. As a result the fluctuation of the current ID1 is reduced even in a wide range of working temperatures and furthermore the safety is assured to the thermal runaway owing to the negative temperature characteristic secured.

Abstract: PURPOSE:To improve sharply the sensitivity in detection of a current by forming a magnetooptical element of a crystal substance having yttrium, iron and garnet and by providing the element in a part of an iron core. CONSTITUTION:A gap 3 is formed in an annular iron core 2, for instance, which is so disposed as to surround a conductor 1, and a magnetooptical element 4 formed of a crystal substance having yttrium, iron and garnet is inserted into the gap 3.

Title: Lithium secondary battery
Inventor: KURIYAMA KAZUYA
IPC: H01M10/052
Filed: 1989-07-06
Abstract: PURPOSE:To improve the charging/discharging characteristics as well as the strong load characteristic at low temps. by using a mixture liquid of specific compounds as organic solvent for electrolyte. CONSTITUTION:As organic solvent for electrolyte, a mixture liquid is used consisting of propylene carbonate(PC), ethylene carbonate(EC), dimetoxyethane(CME), and 2-methyltetrahydrofuran. Generally a solvent with higher dielectric factor provides a higher degree of ion dissolution for the solute, which heightens the electroconductivity of the electrolytic solution. If attention is paid to only this point, it is considered that the EC/DME type using EC with a high dielectric factor is more favorable than the PC/DME type. However, the EC/DME type is not serviceable at a low temp. because the EC solidifies. Thus PC, EC, and DME are added to provide serviceability even at low temp. Further, adding of 2ME-THF enhances the charging/discharging efficiency.
