Title: Production of catalyst for purification of exhaust gas
Inventor: YAMASHITA KOICHI
IPC: B01J29/46
Filed: 1990-03-16
Abstract: PURPOSE:To easily produce a catalyst for purification of exhaust gas having enhanced NOx removing performance by supporting a transition metal and/or an alkaline earth metal on specified zeolite by ion exchange and heat-treating the zeolite. CONSTITUTION:A transition metal such as Cu or Mg and/or an alkaline earth metal is supported on zeolite having 5-1,000 ratio of Si to Al, e.g. ZSM-5 by ion exchange in an aq. soln. The zeolite is then heat-treated usually at about 500-800 deg.C for several hr in a flow of an inert gas such as Ar or N2 mixed with 0.05-5vol.% hydrogen or hydrocarbon such as methane or in a flow of air mixed with a prescribed amt. of water. Since the percentage of the catalytic metal acting as an active site is increased or the basicity of the resulting catalyst is increased, the catalyst accelerates the decomposition of NO molecules and increases the rate of removal of NO.

Title: Digital input device
Inventor: TOSHIMA AKIHIKO
IPC: G06F13/00
Filed: 1986-03-26
Abstract: PURPOSE:To eliminate a need for continuous data-supervisory by providing a microcomputer incorporating a timer that is operated by clock pulses from a CPU input/output bus to which said microcomputer is connected and a storage device to store the state of a sensor. CONSTITUTION:The microcomputer 27 is made start its operation by a start command from the CPU 21, and outputs an input-enable signal to a sensor control part 23 to make the sensor able to scan. If an input data varies at a point of time, the computer 27 operates the incorporating timer by a signal from a sensor control part 23 and, after the lapse of a time set beforehand or at the point of time when the input data varies again, terminates the operation of the timer, and interrupts the CPU 21. When interrupted, the CPU 21 reads the states of the sensor stored in storage devices 28, 29, and 30 as well as the times of their durations. In such a way, the application software provides the sensor-operation supervisory by means of operation completion interruption. Hence, the input data to the sensor needs not to be held at all time, and the counting value of the timer can be set by a digital input device independently.

Filed: 1979-05-29
Abstract: PURPOSE:To improve the resistance to an AC magnetic field of a motor-carrying electronic clock, by employing therein an anti-magnetism plate consisting of a lamination of a plurality of sheets of a material having a high magnetic permeability with an insulating film inserted therebetween. CONSTITUTION:Sheets 6-a of a material having a high magnetic permeability and an insulating film 6-b are laminated, and the resulting product is used as an anti- magnetism plate for preventing a magnetic field from being applied to a motor in an electronic clock from the outside. When an AC magnetic field is applied to such an anti-magnetism plate of a laminated structure, outer and inner portions of the two layers 6-a, each of which consists of a permalloy, etc. remain to be highly permeable in magnetism. A total thickness of such portions of the layers 6-a that remain to be highly magnetically permeable is greater than the thickness of similar portions of an anti-magnetism plate which is a solid sheet material having a high magnetic permeability. Accordingly, the resistance to an AC magnetic field of an anti-magnetism plate based upon this invention can be equivalently increased.

Abstract: PURPOSE:To make it possible to control the temperature or flow rate by changing the number of flow passageways between plates, the change resulting in changes in heating surface area, and flow velocity and flow rate between plates, by means of control of a selector valve. CONSTITUTION:Plates 1 are put together in a multilayer structure with framelike gaskets 2, 3 interposed therebetween; heat exchanger passageways (a), (b) for two fluids are formed alternately between the plates. A partition plate 4 divides the duct into a plurality of passageways C1, C2; the end of each passageway is stopped with a stopper plate 5 at different positions in the direction of laying of the plates 1. The selector valve 6 when placed at the position P1 passes the fluid through both the two passageways, only through the passageway C1 when placed at the position P2, and only through the passageway C2 when placed at the position P3. When the number of the flow passageways is reduced to a half with the selector valve at the position P2 or P3, for example, a cleansing liquid can be made to flow at twice the velocity and at twice the flow rate so as to enhance the cleansing effect.

Title: Water content measuring apparatus for sludge
Inventor: INOUE KIYOSHI
IPC: G01N15/06
Filed: 1986-03-27
Abstract: PURPOSE:To achieve a higher reliability of a measured value, by analyzing the reflected wave of an ultrasonic wave irradiated to the surface of sludge to measure the water content thereof. CONSTITUTION:Sludge 16 being dewatered is transported to the right from the left with a belt conveyor 17. In this process, a height uniforming roller unit 14 is used to uniform the height of the sludge 16. As the sludge 16 passes under an electrostrictive element 10 mounted inside a horn 9, an ultrasonic wave irradiates the surface thereof 16 and the reflected wave thereof is detected with a microphone 12. Generally, a relatively hard sludge with a low water content has a higher reflectance of the ultrasonic wave while a soft sludge with a high water content absorbs the ultrasonic wave excellently. Thus, the water content of the sludge 16 can be determined by the intensity of the reflected wave detected by the microphone 12.

Title: Cutting method of brittle material
Inventor: YAMADA TORU
IPC: B23K26/40
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To cut a brittle material with high positional precision of cutting surface and low pressure by forming a streak by laser beam machining in a cutting method by preliminarily providing a streak for designating the section to be cut and applying a pressure to the side surface of the streak. SOLUTION: When a pressure is added to a brittle material 2 through a pressure transmitting cylinder 7 consisting of a material having a Young's modulus smaller than that of the brittle material 2, the pressure is added to the respective side surfaces of the pressure transmitting cylinder 7 and the brittle material 2, and each of the pressure transmitting cylinder 7 and the brittle material 2 is tend to axially extend. At this time, since the elongation of the pressure transmitting cylinder 7 with the smaller Young's modulus is larger than that of the brittle material 2, a frictional force is generated between the pressure transmitting cylinder 7 and the brittle material 2, and the brittle material 2 suffers from a tensile strength by the frictional force. According to this, the brittle material 2 having a streak 2 formed by laser beam machining can be cut with a lower pressure.
