Title: Automatic centering die for cold forging
Inventor: MIYAZAKI TAKESHI
IPC: B21J13/02
Filed: 1983-03-16
Abstract: PURPOSE:To simplify center adjusting work before starting work by fitting a moving die to the fitting part of a fixed die through respective guide and adjusting deviation of axis by a gap provided between the die and the frame. CONSTITUTION:Before starting work, axes of a moving die 11 and a fixed die 12 are adjusted to approximate coincidence (deviation about 0.1mm.), and a material to be worked is set to working section 12a of the fixed die 12. When the die is closed by the moving die 11, the moving die 11 pushes the fixed die 12 through the material to be worked. The guide plane 11b of the moving die 11 comes into contact with the guide plane 22c of the fitting part 22, and the tip of the moving die 11 is inserted into the recessed part 22a of the fitting part 22. As there is a gap (h) (about 0.1mm.) between frames 14, 15 of the moving die and fitting part 22 to allow moving in the direction perpendicular to the direction of closing the die, some deviation is absorbed and the moving die 11 can be inserted into the recessed part 22 of fitting part easily.

IPC: A01K63/04
Filed: 1993-03-04
Abstract: PURPOSE:To ensure aerated surface water to be fed at low cost into the deep layer of water for fish culture. CONSTITUTION:The surface water of water for fish culture is bubbled in a scooping up way, and a stream is developed by a waterwheel 1 to forcedly dissolve the oxygen in air in the surface water. A tilted water guide plate 13 to slantly block the stream and direct it downward is placed at a position on the downstream side of the stream relative to the waterwheel 1 to forcedly feed the aerated surface water into the deep layer underwater, thus ensuring oxygen feed into the deep layer to be made by simply driving the waterwheel 1.

Title: Solid electrolytic capacitor
Inventor: MORIMOTO TAKESHI
IPC: H01G9/028
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a solid electrolytic capacitor having small leakage current and stable performance by forming a solid electrolyte layer made of conductive polymer compound on an aluminum anode foil reinforced at its four sides with a reinforcing frame. CONSTITUTION:A solid electrolyte layer made of conductive polymer compound is formed on an aluminum anode foil reinforced at four sides with a reinforcing frame. That is, since an anode foil used for an aluminum electrolytic capacitor is generally thin of several tens of microns, the foil is flexible. When it is used in combination with solid electrolyte, a leakage current is increased even by a small impact during manufacturing. Accordingly, the four sides of the aluminum anode foil are reinforced by a reinforcing frame to remove its defect, thereby reducing the leakage current. Thus, the leakage current by the use of conductive polymer compound as the solid electrolyte is reduced to obtain a solid electrolytic capacitor having stable performance.

Abstract: PURPOSE: To provide a synthetic aperture radar which comprises a uniform noise equivalent backscattering coefficient inside an observation width by using a multibeam antenna or a molded beam antenna. CONSTITUTION: A transmitted signal comprising the prescribed number of repetition pulses generated by a chirp pulse generator 4 is amplified by a high-output amplifier 5 so as to be directed to a transmission-reception branching filter 6.

In the multibeam antenna 7, aperture faces are constituted of the arrays 9a, 9b which are provided with (m) pieces of radiation element arrangements in an azimuth direction and with (n) pieces of radiation element arrangements in a range direction. In addition, respective radiation faces of the arrays 9a, 9b are set in advance in such a way that an inphase distribution is obtained in the azimuth direction and that a prescribed direction beam is obtained in the range direction. Consequently, it is possible to suppress the change width of a noise equivalent backscattering coefficient inside an observation width.

Abstract: PROBLEM TO BE SOLVED: To perform excellent recording/reproducing and to prevent also a margin for a tilt and defocus from being damaged by constituting the numerical aperture NA of the objective lens of the optical path of the outward path from a semiconductor laser to an optical disk larger than the numerical aperture NA of the backward path from the optical disk. SOLUTION: In the outward path, a beam emitted from the semiconductor laser 1-1 propagates through a separation element 1-5 to be converged on the optical disk 1-2 by the objective lens 1-3. In the backward path, the beam reflected by the optical disk 1-2 passes through the objective lens 1-3 to be diffracted by the separation element 1-5 and falls on first detectors 1-4-1, 1-4-2. At this time, the numerical aperture NA1 of the outward path is decided by an objective lens holder 1-6. On the other hand, the numerical aperture NA2 of the backward path is not decided by the objective lens holder 1-6 but decided by an aperture element consisting of a λ/4 plate 1-7 and a diffraction grating 1-8. In such a case, the numerical aperture NA1 becomes larger than numerical aperture NA2.
