Patent JP-H08274663-A (JP)
Title: Radio receiver
Inventor: NOJIRI HIDETOMO
IPC: H04B1/10
Filed: 1995-03-31
Abstract: PURPOSE: To surely eliminate the noise of long pulse width and the noise of short generation period also. CONSTITUTION: It is noticed that an FM reception part is idle at the time or reception or AM broadcast, the AM intermediate frequency signal passing an AM band pass filter 5 is inputted to a limiter amplifier 14 and has the amplitude limited. The noise component is demodulated by a quadrature detection circuit 15, and only the noise component is extracted by a band pass filter 19, and the noise component is converted to a DC voltage by a noise amplification circuit 20 and a noise detection circuit 21. An AM intermediate frequency amplification circuit 6 is subjected to AGC control by this DC voltage. Thus, an influence of noise is reduced not to output the noise offending ears even if a noise pulse is continuously generated with a short period or the pulse width of each noise pulse is long. The FM reception part is applied to obtain a maximum noise reduction effect without costing neither making a receiver main body large-sized.

Filed: 1983-04-30
Abstract: PURPOSE:To make a PLL operation optimum by switch-controlling a time constant of a low-pass filter in accordance with a synchronous state and an asynchronous state by an output of a detector. CONSTITUTION:A detector 4 for discriminating a synchronizing state and an asynchronous state of a phase locked loop circuit is provided.

Title: Image forming device
IPC: B41J2/32
Filed: 1992-03-31
Abstract: PURPOSE:To prevent an occurrence of an unevenness in an image by a method wherein a head part of a thermal recording element is opposed to a developer holding body across a film-form latent image body, and at the time of forming a latent image, the head part presses the film-form latent image body on the surface of the developer holding body. CONSTITUTION:In a developing part 3, a developing roll 1.3 is depressed against the rear surface of a film-form latent image body 1 on the opposite side to a head part of a thermal recording element 7. The developing roll 13 rotates at a speed equal to or higher than the latent image body 1 while pressing the film-form latent image body 1 against the head part of the thermal recording element 7 to stably feed the film-form latent image body 1 and uniformly depress the surface of the body 1 against the head part of the thermal recording element 7, thereby forming an even and uniform image. Meantime, a one-component nonmagnetic developer 11 is supplied to the surface of the developing roll 13 by a supply roll 15 to adhere thereto. The developer 11 held on the surface of the developing roll 13 is partially scraped by a regulating blade 14 to be made a thin layer. In this manner, the rear surface of the film-form latent image body 1 and the top surface of the developer 11 are brought into uniform contact with each other. By electrifying the developer 11 with a suitable polarity, the image is developed with a high quality.

Title: Hermetic electrically driven compressor

IPC: F04B39/00
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of efficiency of a hermetic electrically driven compressor and attenuate pulsative motion of abruptly discharged gas by forming a pass hole having a diameter smaller than that of a communication hole on a thin portion of a valve plate. SOLUTION: A cylinder head 14 having a discharge chamber 13 is fixed to a cylinder 2 through a valve plate 10. A pass hole 17 is formed on a thin portion 18 of the valve plate 10, which hole 17 is opened to a communication hole 16 communicated with the discharge chamber 13 and a muffler arranged on a cylinder block 3, and has a diameter smaller than that of the communication hole 16. The gas inside the cylinder 2 is compressed to higher the gas pressure inside the cylinder 2 than that of the discharge chamber 13. Then the compressed gas is abruptly discharged from a discharge hole 8 to the discharge chamber 13 of the cylinder head 14. Since the pass hole 17 is formed on the thin portion 18, pressure loss is the more reduced, the thinner the portion is.  It is thus possible to attenuate pulsative motion of the abruptly discharged gas without deteriorating efficiency of a hermetic electrically driven compressor.

Title: Extractive separation of niobium compound

IPC: C22B34/24
Filed: 1983-04-30
Abstract: PURPOSE:To recover niobium from a waste material containing a small amount of niobium in high concn. and high efficiency, by concentrating a metal chloride- containing hydrochloric acid solution prepared by eluting an inorg. mixture containing a small amount of niobium chloride with an aqueous hydrochloric acid solution with a specific concn. CONSTITUTION:An inorg. powdery mixture in which a small amount of NbCl2 coexists along with chlorides of Ti, Ta and Zr remaining after main metal chloride is extracted from a raw ore by treating the same with chlorine is used as a stock material. This stock material is thrown into a proper amount (about three times the vol. of the stock material) of a 15-25% aqueous hydrochloric acid solution and stirring is performed for about 20hr at a room temp. to eluate soluble metal chloride in the stock material. Subsequently, insolubles are removed by filtering while the obtained metal chloride-containing hydrochloric acid solution being the filtrate is concentrated but, because an aqueous hydrochloric acid solution is subjected to azeotropy at a hydrochloric acid concn. of about 20%, said solution is concentrated until the hydrochloric acid concn. becomes constant at about 20%. Moreover, the solubility of metal chloride to the 20% aqueous hydrochloric acid solution is considerably different for every metal and, because the solubility of NbCl2 is small, it is precipitated as a crystal.
