Title: Catalyst for synthesis of hydrocarbon
Inventor: MUKAI YUTAKA
IPC: C07C67/00
Filed: 1984-06-13
Abstract: PURPOSE:To obtain a catalyst suitable for the synthesis of hydrocarbon oil corresponding to a petroleum intermediate fraction from carbon monoxide and hydrogen with high yield, by using a material prepared from an alfol alumina gel as a carrier. CONSTITUTION:In a metal supported catalyst used in reaction for the synthesis of hydrocarbon consisting of carbon monoxide and hydrogen, as the metal supported catalyst, a ruthenium supported catalyst is used and a carrier is prepared by a method wherein the alfol alumina gel obtained from Al-alkoxide is kneaded with an aqueous acid solution containing no sulfur and the kneaded mixture is dried before baked at 350-800 deg.C. In synthesizing hydrocarbon from a gaseous mixture consisting of CO and H by using this catalyst, the catalyst is dispersed in a solvent and used in a suspension bed system. By this method, hydrocarbon oil corresponding to a petroleum intermediate fraction can be synthesized in high yeild.

Title: Dispensing nozzle and fixed volume dispensing pump for liquid analyzer for medical inspection
Inventor: SAKAMAKI TAKESHI
IPC: G01N1/00
Filed: 1987-05-20
Abstract: PURPOSE:To enable fixed volume dispensing by providing a dispensing nozzle having a gas-liquid separating membrane in an internal prescribed height position and means for pressure reduction and pressurization which can change over a pressure reduction effect and pressurization effect. CONSTITUTION:The dispensing nozzle 1 is provided with the gas-liquid separating membrane 2 in the adequate height position in the internal space of the nozzle 1. The air in the nozzle 1 is passed through the membrane 2 and is moved to a connecting pipe 4 side by immersing the nozzle 1 tip into a sample S and communicating the nozzle with a negative pressure pump 6 by means of a 3-way selector valve 3. The air pressure in the nozzle 1, is therefore, dropped and the sample S in a tank T is sucked into the nozzle 1. The suction of the sample S is stopped at the point of the time when the sample S arrives at the membrane 2, then the pump 6 is stopped by a pressure sensor 7 and a controller 8. The valve 3 is changed over to a positive pressure pump 5 side and dispensing is executed by operating the pump 5 in the case of dispensing the sample S in the nozzle 1 into a reaction cell. The fixed volume dispensing is, therefore, enabled if the setting position of the membrane 2 in the nozzle 1 is set to meet the respective specified volume of each sample S to be sucked.

Filed: 1989-05-16
Abstract: PURPOSE:To set an optimum slice level by providing a read condition changeover means switching the read condition of a slice level or the like into plural different conditions during read of one original picture. CONSTITUTION:A background density spot appears on areas 15a, 15c and when an area 15b is read while an original picture described with a black picture is being scanned, a CPU 1 sets a highest slice level to a picture data processing section 8 at the start of reading.

Then a picture data read by a linear image sensor 10 is binarized for each slice level at a picture data processing unit 8 to obtain n-kind of binary read pictures. Then an optimum picture is selected out of the n-kind of the pictures and the corresponding slice level is set manually. Thus, the optimum slice level is adjusted without provision of a special circuit.

Filed: 1982-07-14
Abstract: PURPOSE:To prevent a decrease of capacity and stably obtain the capacity, by improving diffusion of dilute sulfuric acid from a paper unit to the inside of a plate. CONSTITUTION:If a material formed to a gel state by sulfuric acid, for instance, water glass is applied to a surface of a plates 1, 3 or a surface of a paper unit 2, the water glass, being liquid simultaneously of high viscosity, never intrudes into a hole of the plates 1, 3 but forms a film with the surface, further said film removes ruggedness of the plates 1, 3 to form a smooth surface. Such treatment is applied to the plates 1, 3 and the paper unit 2, and these plates and unit constitute an element, then if an electrolyte of dilute sulfuric acid is injected, the water glass is changed to a gel state. The water glass formed to a gel state is buried in a clearance between the plate 1, 3 and the paper unit 2, further dilute sulfuric acid is held also in the gel of the clearance, and the dilute sulfuric acid is smoothly diffused from the paper unit 2 to the inside of the plates 1, 3 at electric discharge time, in consequence discharge capacity is left not to be decreased. Also when the water glass is applied to the surface of the paper unit, a similar effect is observed.

IPC: H02H3/44
Filed: 1987-05-21
Abstract: PURPOSE:To prevent a relay from malfunctioning by initializing a current variation detecting function under the condition that a current variation is negative. CONSTITUTION:An input current T is sampled by a current variation detecting means 10. When the momentary value of a current at a sampling time point (n) is In, the momentary value of a weighted current is Jn, a current variation is  In, a sampling period is  t, and time constant is td, current variation  In is obtained by equations I and II. However, the momentary values In, In-1 of the currents during the processing are compared. In case of In<In-1, the values of the In and the Jn-1 are set to zero, and the operation in which the current variation  In becomes zero is conducted. If the current variation  In exceeds a predetermined value after this calculation, an output is produced. Even when it is largely raised immediately after the current variation becomes negative, it can be effectively detected.

Abstract: PURPOSE: To prevent entry of excessive fluid into rear wheel brakes by installing an inertial chamber in the main flow passage and causing the inertial member 7 to be driven by the powerful flow of pressurizing medium in the main passage to actuate the inertia valve prior to deceleration.  
     CONSTITUTION: Fluid streaming from a master cylinder flows through a passage 1, an inertia chamber 4 and a passage 3' before it is introduced into a control valve 13. In case that a large amount of fluid streams rapidly in slight contact with a part of the inertia ball 7, the ball is provided with an inlet 9 and an outlet 10 for the main passage of fluid to ensure that it be drawn closer toward a side contacted by a rapid stream generated by a difference in pressure in proportion to a difference in flow velocity on each side of the ball and that viscose resistance generates rotational moment which moves the ball toward the valve seat. Also, a throttle 8' installed halfway between the valve seat 5 and a enclosure chamber 6 delays the rise of pressure in the chamber 6, thereby preventing excessive entry of fluid into the rear wheel brakes
