Title: Irreversible circuit element
Inventor: HASEGAWA TAKASHI
IPC: H01P1/383
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To make components of the element small in size and light in weight while realizing a broad frequency band for its attenuation characteristic and to reduce the cost by adding a resistor between a center electrode section and ground. SOLUTION: A center electrode section 5 of a lumped constant type isolator 1 is so structured that three 1st-3rd center conductors L1-L3 acting like inductive components are arranged in crossing at an angular interval of 120 deg. on a discoid ferrite disk 8 while being isolated electrically with each other. The center electrode section 5 and capacitor electrodes C1-C3 of ports P1-P3 are formed on same potential and a resistor 15 is added between the center electrode section 5 and ground, then a broad frequency band is realized for the attenuation characteristic. Thus, a reflected wave is surely absorbed and intrusion of an undesired wave is prevented. That is, since the isolator is operated at a region where a change in a permeability μ' of a ferrite with respect to a frequency HZ is small through the addition of the resistor, the band width is extended by that.

Filed: 1979-06-20
Abstract: PURPOSE:To simplify a circuit construction and prevent contamination due to impurities, by detecting the ratio of an electrical current flowing through a mask, to a faradaic current and detecting the deflection of an ion beam to monitor it. CONSTITUTION:An ion beam 3 produced by an ion beam generator 1 collides against a mask plate 4 to cause an electrical current Im. This current Im and a current If from a Faraday chamber 6 are applied to current integrators 9, 8 so that these currents are averaged. The averaged value is applied to a divider 10 which performs division to generate an output eo. When this output falls below a set level, a Schmitt trigger circuit 12 produces an alarm signal. The current If is converted into a voltage signal by a voltage converter 14. The voltage signal is applied to an averaging circuit 17 or 18 through an analogue switch 16 depending on the positive or negative part of the output scanning waves of a zero detection circuit 13 which detects the zero level of the potential on a deflection electrode 2. An output produced as a result of the averaging by the circuits 17, 18 is applied to a subtraction circuit 19. When the difference output of the circuit 19 exceeds a set value, another zero detection circuit 21 produces an alarm signal.

Title: Production of carbide of plant
Inventor: NAKANISHI YOICHIRO
IPC: C01B31/02
Filed: 1991-02-18
Abstract: PURPOSE:To obtain a carbide having high strength in high yield by previously oxidizing a plant before carbonization of plant to prevent the formation of low-molecular weight substances resulting from rapid and extreme decomposition of the plant, successively heating and carbonizing the plant in a gas flow under a nonoxidizing atmosphere. CONSTITUTION:For example, flowers (small branches or leaves) of rose, Camellia sasanqua Thunb., or rose of Sharon or fruits of Japanese chestnut with bur are dried. The dried plants are previously oxidized at 200-300 deg.C, heated in a gas flow under a nonoxidizing atmosphere using a gas of N2 gas, Ar gas or H2 gas and carbonized to give a carbide of plant. This method provides a carbide having excellent strength in a relatively high yield, extremely shortens a carbonization time and shows excellent productivity. Since plants are carbonized in the gas flow, air is not fed into a container, will not cause oxidation, the decomposition products are discharged out of the container and clean surface of the carbide can be maintained.

Abstract: PURPOSE:To obtain the substrate having a thermal conductivity higher than an alumina sintered body and a smaller coefficient of thermal expansion by using a sintered body containing Si carbide at the main component and Be oxide in a specific amount. CONSTITUTION:The sintered body containing Si carbide as the main component and Be oxide at 1-9wt% is used. Said sintered body should have a specific resistivity (y) of 10<10>OMEGAcm or more at room temperature, and it is appropriate to contain Be oxide at five times or more of the content of the following as the Al oxide of Al the impurity in said Si carbide. For example, the specific resistivity (25 deg.C) of an Si carbide sintered body obtained by addition of Be oxide to the powder of Si carbide of 98% purity containing about 0.1% of Al oxide as the impurity and then by sintering is as shown in the figure: a high specific resistivity can be obtained at a doped amount (x) of 1wt% or more, and a high density sintered body can be obtained. On the other hand, when the doped amount (x) is 9wt% or more, the specific resistivity (y) becomes saturated, and the sintered body tends to have many pores.
