Title: Continuous electric power supply circuit controlled by reversible converter
Inventor: FARINE PIERRE ANDRE
IPC: G04G19/02
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To minimize a placing space by providing a switch for continuously supplying power, by transmitting the energy from an intermittent power source to an energy accumulation means with a converter in normal direction or discharging the accumulated energy to the power source in reverse direction. SOLUTION: An intermittent power source G in steady state supplies power to a capacitor 3 via a diode 4, and a converter 5 transmits a part of the power to an energy accumulation means 6 to increase the accumulated energy. In the secondary state, when the intermittent power source G lowers the voltage, the accumulated energy in the capacitor C is discharged to a supply circuit 1 via the converter 5. The reversible converter 5 is provided with, for example, a switch circuit consisting of an inductance L and static switches T1 to T4 and a diode D. By switching them, the direction of the converter 5 and the electric conversion ratio are reversed. By this, long power supply life is attained and the simple supply circuit 1 with small number of parts can be obtained.

Title: Spool for superconducting highly accurate magnetic field magnet
Inventor: HARA NOBUHIRO
IPC: H01F6/00
Filed: 1991-07-31
Abstract: PURPOSE:To provide a spool for a superconducting magnet and the magnet to be used in applications where a desired magnetic field distribution is to be correctly obtained. CONSTITUTION:After an insulator 2 is fixed to a metallic spool 1 which has been roughly worked, the insulator 2 is worked to obtain a coil groove 3 of a desired size. Thus a magnetic field distribution approximately as designed can be obtained even if the spool has been cooled for use, whereby correction of the magnetic field distribution is completed in a short time. In addition, since a rigid superconducting magnet can be obtained, quenching is not likely to occur and the spool can be used with a load factor increased, so that an amount of superconducting lines used can be reduced.

Title: Radioactivating foil
Inventor: TOKUNO ATSUSHI
IPC: G01T3/00
Filed: 1984-09-14
Abstract: PURPOSE:To make possible the simultaneous measurement of neutron energy spectra over a wide range in a short period without spoiling the ease of a radioactivating foil method by using the foil in which plural nuclides are combined to one in the form of an alloy or mixture. CONSTITUTION:For example, gold, nickel, aluminum, titanium and alloy are selected as the nuclides to constitute the foil and are mixed at a suitable ratio. The mixture is melted at a high temp. to manufacture the alloy which is then molded to a disk shape. Such disk shape alloy is used. When the foil is subjected to irradiation of neutrons, the foil is made radioactive by the reaction of the neutrons in the energy range different with the nuclides and atomic nuclei and the foil releases gamma rays. Since just one foil is required for the measurement, the time for the measurement is reduced.

Title: Method for deceiving flying body
Inventor: NISHIYAMA JUNICHI
IPC: F41H3/00
Filed: 1991-07-31
Abstract: PURPOSE:To deceive an anti-radar missile (ARM) so as to reduce damage by radiating a radar beam toward the ground from a radar installed on the ground, and orienting the reflected beam toward the ARM, and forming a virtual image from the radar beam. CONSTITUTION:A radar beam 2a is radiated toward an ARM 3 from a radar 1 installed on the ground and a radar beam 2 is radiated toward the ground 5. The beam 2 is reflected at the ground 5 and oriented toward the ARM 3 to form a virtual image 4 of the radar 1. The ARM 3 reacts not only to the beam 2a but also to the beam 2 reflected from the ground 5 and therefore flies toward the middle point between the beams 2a, 2. Thereby the accuracy at which the ARM 3 hits a target is deteriorated and damage to the radar 1 is reduced.

Filed: 1991-07-31
Abstract: PURPOSE:To reduce the number of the parts of a photodetection system circuit by using multiply divided photodiodes for the second photoelectric elements. CONSTITUTION:Photoelectric currents from a photodiode PDA of a photoelectric element 11 are converted into a signal voltage SA by a resistance R1 and an operating amplifier OP1, and an output equivalent to unnecessitated incident light components is subtracted by the photoelectric currents from a corresponding PD1 of a photoelectric element 12 and a variable resistance VR1. In the same way, the unnecessitated incident light components are removed from the outputs of the PDB-D of the element 11 by the outputs of the PD2-4 of the element 12. The total sum of the photoelectric currents of the PD1-4 can be obtained by a resistance RC, a signal SM for the decrease of the voltage of the RC is obtained by using a voltage source E for an inverse bias as a reference, and the intensity of a light beam can be controlled by the signal SM. Thus, the unnecessitated incident light components can be availably removed by the reduced number of parts.

Title: Buried type semiconductor laser and manufacture thereof
Inventor: INOUE TAKESHI
IPC: H01S5/00
Filed: 1990-07-20
Abstract: PURPOSE:To form a window structure and a buried layer without allowing an active layer to come into contact with the atmosphere by using the plane of [110] as a growth stop plane. CONSTITUTION:After the formation of an n-type clad layer 12 and an n-type guide layer 13 in a [100] n-type GaAs substrate 11, a diffraction grating 14 is formed on the n-type guide layer 13. Then, a mesa stripe is formed. In succession, an n-type buffer layer 15, an active layer 16, a p-type clad first layer 17, an n-type block layer 18, a p-type clad second layer 19, and a p-type cap layer 20 are grown in this order. When an attempt is made to select a condition where the n-type buffer layer 15, the active layer 16, and the p-type clad first layer 17 are required to form the plane of [110] as the growth stop plane, a roof type structure is obtained so that the active layer 16 may be separated from the top of the mesa and from the side of the mesa. After the mesa is covered with the plane of [110], the n-type block layer 18 is formed in such a manner that it may surround the mesa. A p-type electrode 21 is installed on a p-type cap layer 20 where an n-type electrode 22 is installed on the rear side of the substrate 11. This construction makes it possible to manufacture a buried type semiconductor laser with a window structure without bringing the active layer in contact with the atmosphere.

Title: Decurl mechanism and recording device using decurl mechanism
Inventor: SASAI KEIZO
IPC: B65H23/34
Filed: 1989-07-27
Abstract: PURPOSE:To make curl correction positively without enlarging the contact angle of sheet material with a decurl member more than necessary by setting the radius of curvature of the curved surface of a guide member larger than that of the decurl member. CONSTITUTION:At the time of conveying sheet material, a shifting means 26 stops in the balanced state between tension supplied to the sheet material and energizing force by an energizing means 35. Accordingly, when the tension is large, the influence of the energizing force on the shifting means 26 is small, and the acting quantity of the shifting means 26 becomes small and therefore the curvature of the sheet material becomes small. On the other hand, when the tension is small, the moving quantity of the shifting means 26 becomes large, and the curvature of the sheet material thereby becomes large. Curl correction corresponding to curl strength can be therefore made. In this case, the radius of curvature of the curved surface of a guide member 25 is larger than that of a decurl member 22, so that curl correction can be make positively without enlarging the contact angle of the sheet material with the decurl member 22 more than necessary.
