Title: Dielectric filter
Inventor: MAEDA TAKEYASU
IPC: H01P7/04
Filed: 1982-12-21
Abstract: PURPOSE:To attain easily formation of a wide band by connecting the intra-hole conductors to each other which form a resonator by means of a capacitor. CONSTITUTION:A chip capacitor 5 is provided between resonators 2 respectively on a non-metallized outer surface (hole opening surface) 1a of a dielectric block 1. Then resonators (intra-hole conductors) 2 are connected to each other by those capacitors 5. Therefore the resonators 2 are connected to each other by the capacitor 5 in addition to the magnetic field connection using a gap formed between resonators 2. Thus it is possible to set optionally the coupling capacity between resonators 2 by selecting properly the capacity of the capacitor 5. In such a way, a wide band can be obtained easily.

Inventor: NAGAI TAKAATSU
IPC: C03C13/06
Filed: 1992-07-31
Abstract: PURPOSE:To obtain a raw material for producing rock wool for cupola by incorporating an organic and/or inorganic binder in a mixture of water granulated slag and a component regulating material followed by granulation to a specified granular diameter. CONSTITUTION:The water granulated slag (e.g. blast-furnace water granulated slag) may be unprocessed one ca. 0.1-5mm in granular diameter, or, may be in the form of lightly ground finer granules, where appropriate. Or, with not only water granulated slag alone but, other kinds of waste slag (e.g. waste cotton) may be incorporated. As lime-rich blast-furnace water-granulated slag is deficient in silica for this feedstock, silica rock, etc., is needed to be incorporated as component regulating material in this slag (usually, kaolin, slag produced through copper refining, basalt). For the granulation, a feedstock to be granulated is incorporated with 5-40wt.%, based on the feedstock, of an organic binder such as polyvinyl acetate emulsion or CMC along besides an inorganic binder such as cement. The granular diameter of the granulated product is pref. 10-150mm from the standpoint of its melting in a cupola. For rock wool production, a cupola is charged with such a granulated product, which is then melted and the resulting melt at 1400-1500 deg.C is made into fibers (rock wool) by centrifugal force etc.

Filed: 1983-11-28
Abstract: PURPOSE:To reduce memory capacity by suppressing the execution of a microinstruction whose error is detected, and continuing the execution at another microprogram instruction of a microprogram stored in a control storage area. CONSTITUTION:When a parity checking circuit 4 detects a parity error during the execution of a microinstruction in an area A of the control storage CS1 and a detection line 400 goes up to 1, an inverter 56 outputs logic 0 to an execution indication signal line 503.

IPC: H01S3/10
Filed: 1994-08-25
Abstract: PURPOSE: To amplify in the state of a large S/N ratio without converting the optical signal of a desired wavelength range to an electric signal with high amplification factor by so selecting semiconductor crystal fine grains dispersed in the core of an optical waveguide that the band gap wavelength corresponds to the wavelength of a desired optical signal.

The semiconductor dispersed in the fine grain state does not have polarizing characteristics, and the signal light is not attenuated by the polarization of the light. Thus, the signal of the 0.8, 1.3 or 1.55μm of the band is not electrically converted, but can be directly amplified in high efficiency.

Abstract: PURPOSE:To reduce the weight of an impeller and to improve blast efficiency by a method wherein a plurality of blades are held between the nip formed by front and rear shrouds to form an impeller, and a fold edge making contact with the inner end part of the blade is formed to the port edge of the intake air port of the front shroud. CONSTITUTION:An impeller is formed with a plurality of blades 25, a front shroud 31 provided at its central part with an intake air port 31a, and a rear shroud 32 to integrally form them by means of caulked parts 33. The edge of the intake air port 31a of the front shroud 31 is folded toward the motor side to form a fold line 31b, which is brought into contact with the inner end surface of the blade 25. Thereby, since the blade 25 is functioned as reinforcement for a centrifugal force, strength is improved sharply. Since strength is improved, even when caulked parts 33 are reduced from three parts to two parts per one blade 25, there is no problem on strength, and efficiency can be improved.
