Filed: 1985-02-28
Abstract: PURPOSE:To obtain a sintered body having high density without having pores by applying a microwave as a pretreatment to a molding formed of a compsn. mixture composed of metals or ceramics by a binder and applying further an electrostatic field thereto then removing the binder and subjecting the molding to normal sintering. CONSTITUTION:The compsn. mixture for sintering consisting of a mixture composed of the power of >=1 kinds among metals or ceramics such as the oxide, carbide and nitride of the metals and the additive binder is prepd. Such compsn. mixture is exemplified by the compsn. prepd. by adding 23% water as the binder to, for example, 36% kaolin, 33% feldspar, 22% silica sand and the balance limestone, kneading thoroughly the mixture and molding the mixture under pressure within the prescribed mold. The required microwave is applied to such compsn. mixture to scatter quickly the volatile matter in the additive binder from the mixture. An adequate quantity of the electrostatic field is applied thereto simultaneously with the microwave to assist the effect of removing the binder and thereafter the molded mixture is subjected to a pretreatment prior to sintering, then to the normal sintering. The high-density sintered body having no pores is thus obtd.

Inventor: ISHITANI AKIHIKO
IPC: C09K11/08
Filed: 1981-03-16
Abstract: PURPOSE: The titled fluorescent substance emitting red color that is prepared by mixing a fluorescent substance obtained by doping a Eu-activated red fluorescent substance R 2 O 2 S:Eu with a specific amount of Sn, with an electrically conductive material, thus showing improved surface conductivity to low-speed electron rays and increased brightness.  
     CONSTITUTION: A Eu-activated red fluorescent substance R 2 O 2 S:Eu (R is Y, La, Gd, Lu, Sc) is doped with Sn by 0.005W5atomic% based on the R to prepare a fluorescent substance. The product, preferably Y 2 O 2 S:Eu,Sn, is mixed with a conductive material, preferably In 2 O 3 ,SnO 2 :Sb, to give the objective fluorescent substance.  
     EFFECT: The product is free from Cd. Since Sn only improves the surface conductivity of R 2 O 2 S and does not relate to the emission characteristics of Eu, the relationship between the emission brightness and Eu activation, known in the excitation with high speed electron rays, also is kept in low-speed.

Title: Signal reception system
Inventor: KURODA KIYOHIKO
IPC: H04M19/00
Filed: 1985-02-27
Abstract: PURPOSE:To eliminate the need for a separate signal receiver even when a transmission loss of a line is changed by providing one-way amplifier inserted to a 4-wire input of a control signal reception section in a 2/4-wire converting section of a network and bypassed at voice reception so as to apply control depending on the input signal level. CONSTITUTION:A level adjusting circuit 15 detects a signal level from a subscriber terminal device 1 to adjust the gain of the one-way amplifier 14 in response to the detected level and the output level is kept constant automatically. The connecting procedure between the terminal device 1 and an exchange is definite and when a call comes from, e.g., the terminal device 1, a signal such as a PB signal is sent, then the exchange control circuit controls contacts 12, 13 in response to the stage of connection for changeover and adds the amplifier 14 having automatic adjusting function of the level to the 2/4-wire converting section only at the reception of signal. In this case, since the loop of 4-wire part is opened by the network 3, the detour through an opposite subscriber line terminator 4 is caused.

Abstract: PURPOSE:To decrease the damages of a surface, to clean the surface sufficiently and to maintain the cleanliness of the cleaned surface for a long time by intdocuding the mixed gas of hydrogen and deuterium to the surface to be cleaned, and projecting the light from a deuterium lamp on the introduced mixed gas. CONSTITUTION:The mixed gas of hydrogen H2 and deuterium D2 is introduced on the surface of a semiconductor substrate 1 to be cleaned. The light from a deuterium lamp 8 is applied to the introduced gas. At this time, at first, the D2 molecules efficiently absorb the projected light based on the agreement of wavelengths, and radical is obtained. The radical is made to hit the H2 molecules, and energy is moved. The H2 molecules are made to be radical. The radical is returned to the D2 molecules. This change is repeated, and the density of the radicals is enhanced. In this way, the damages of the surface are made less, and the surface can be sufficiently cleaned. The cleanliness of the cleaned surface can be maintained for a long time economically.

Title: Corrosion speed judging device
Inventor: SUGANO KENICHI
IPC: G01N17/00
Filed: 1978-04-05
Abstract: PURPOSE: To obtain the judging device of corrosion speed, by means of the coulostatic method to measure the polarization characteristic by using the specimen metal piece as a working electrode.  
     CONSTITUTION:  An electric charge is accumulated in a capacitor 5 by a power source 6. At this time, the capacitor 5 is electrically non-conductive to a corrosion speed measuring cell 4 by means of a charge adding mechanism 8. The charge accumulated in the capacitor 5 is supplied into a specimen metal piece 1 of the corrosion speed measuring cell 4 through a breaking mechanism 11 which is in closed circuit due to the charge adding mechanism 8. The potential change in the specimen metal piece 1 is converted into the relation of the polarization value η- time t through a reference electrode 2, and measured in a potential diference recording mechanism 9. In this measurement, when the electric double layer of the specimen metal piece 1 is charged to the specified quantity, the breaking mechanism 11 is set in open circuit, and an opening/closing mechanism 12 is set in closed circuit at the same time. Thus, the measurement of η-t curve is started by the potential difference recording mechanism 9. Thus, correct corrosion speed may be judged.

Abstract: PROBLEM TO BE SOLVED: To obtain a bright color picture with a high degree of whiteness by averaging incidence efficiencies of each wave length made incident on each picture element corresponding to each color of the liquid crystal display element. SOLUTION: A hologram which diffracts a parallel light beams from a light source part by wavelengths of R, G, and B and focuses them on picture elements corresponding to respective colors of liquid crystal cells 7, is formed by periodically arranging unit holograms each consisting of a set of three kinds of R, G, and B hologram cells 12R, 12G, and 12B corresponding to an individual picture element of each color, and each of the hologram cells 12R, 12G, and 12B focuses the diffracted light of a specific wavelength on a picture element of a color corresponding to one of the liquid crystal cells 7, and make the light of the other wavelengths exit to the picture elements corresponding to the other colors of the liquid crystal cells 7. Thus, either one kind of the wavelengths of R, G, and B is not so much emphasized as a conventional one, but the incident efficiencies of light of each wavelength can be averaged and a color picture having a high degree whiteness can be displayed.

Title: Signal processing device for secondary surveillance radar
Inventor: MIZUTANI AKIO
IPC: G01S7/32
Filed: 1991-02-08
Abstract: PURPOSE:To conquer the performance limit in IISLS method. CONSTITUTION:A target detection circuit 21 detects a response signal regarded to be true which is contained in a main beam signal. A difference signal judging circuit 22 has a memory circuit in which amplitude evolution data having a normal difference pattern distribution, is set in advance. In this memory circuit, the amplitude evolution for each radar hit of the actually received signal contained in an omega beam signal is memorized. When a detection response signal is input from the target detection circuit 21, the actually obtained amplitude evolution data and the preset amplitude evolution data are compared to judge the agreement and disagreement of the evolution distributions. If the judgement result is in disagreement, a gate circuit 23 prohibits the output of the target detection circuit 21 to be output as the target signal.
