Title: Catalyst for manufacturing ethylene oxide
Inventor: IWAKURA TOMOATSU
IPC: C07D301/10
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to manufacture a long life catalyst for the manufacture of ethylene oxide with high selectivity and superior activity by pretreating a lithium compound and a cesium compound on a porous carrier, then impregnating the porous carrier with a silver commode and the cesium compound through a heating process. SOLUTION: A porous carrier is impregnated with a solution containing a lithium compound and a cesium compound as a pretreatment. Next, the porous carrier bearing lithium and cesium is impregnated with a solution containing a silver compound and the cesium compound and is heat treated. The heating treatment after the impregnation is performed by measuring the temperatures and time required for the deposition of silver on the carrier. Conditions for the deposition of silver present in as much uniformly and fine a particle form as possible on the carrier are selected. The chemical reaction for ethylene to be converted to ethylene oxide using this type of catalyst is performed by routine operation. Thus it is possible to manufacture the ethylene oxide at a high rate of selection under milder conditions compared with a conventional catalyst.

Title: Mr imaging method
Inventor: TAKEO KAZUHIRO
IPC: A61B5/055
Filed: 1991-08-31
Abstract: PURPOSE:To correct the influence of longitudinal relaxation, and also, to improve an S/N of data by executing two times a scan in which the variation directions of the phase encoding amount are reverse, respectively by a snap shot FLASH method, and adding the obtained data by each same phase. CONSTITUTION:A T1 emphatic 180 degree inversion pulse is applied as a preparation pulse together with a slice selection gradient magnetic field Gs, and by inverting selectively a certain slice by 180 degrees, a snap shot FLASH sequence is executed. Also, since the variation direction of a phase encoding amount is set to the opposite direction in a first time and a second time, rearrangement of data of each line is executed, and an addition processing is performed to each data of the same phase encoding amount. As a result, as for the data of each line after the addition, the influence degree of longitudinal. relaxation becomes roughly uniform to the data of any line, and an error caused by a difference of the longitudinal relaxation is corrected. Also, since the data by the same encoding amount are added, an S/N of the data is improved.

Filed: 1983-12-27
Abstract: PURPOSE:To obtain a measured value having high reliability by providing a means for bypassing and supplying ultra-pure water and a means for washing a water tank in the sample intake port of an Na<+> ion electrode meter. CONSTITUTION:Ultra-pure water 37 is supplied from a water feed section 30 to a water tank 1 and thereafter the air in the atm. is supplied to a bubble generating section 5 for specified time at a specified flow rate from an air feed section 40 and is bubbled in the water 37. The water is discharged at a specified rate into a draining section 50 after the end of bubbling and Na<+> ions are measured with an Na<+> ion electrode meter 13. While the bubbling is effected, the ultra- pure water is supplied at a specified rate from a system 70 for bypassing and supplying the ultra-pure water into the sample intake port 13a of the meter 13 by which the concn. of the Na<+> ion in the ultra-pure water is measured without using bubbling to stabilize the background value of the Na<+> ion electrode meter. Washing is accomplished by supplying the ultra-pure water to the tank 1 via a washing system 60 to clean the tank after the pure water used for bubbling is discharged thereby removing the residual Na<+> ions in the water tank.

Filed: 1990-09-19
Abstract: PURPOSE:To recover the display erased on a display with a 'one-touch' operation of a key of a keyboard by providing an operation storage which stores the operations instructed from the keyboard. CONSTITUTION:When an operator wants to stop the operation of a building equipment 1 or to confirm the trouble of the equipment 1, the operator operates a keyboard 10 to confirm the pushed key via a keyboard fetching device 7. An operation storage 9 stores the data recognized by a man-machine processor 6 when the data are sent to the processor 6 from the device 7. The storage 9 contains a storage buffer which stores the latest operation No., the operation No preceding by one time, and the operation No preceding by N times. Then a suite of storage buffers are shifted backward every time a single No or a piece of confirmed data on a screen is received from the processor 6. Then the data received as the latest operation No is stored. Thus it is possible to sequentially store the manual operations and also to regenerate the stored operations. As a result, the operations if erased by the power ON/OFF actions of a device is regenerated on a screen.

Title: Weather radar device
Inventor: FURUTA TADASHI
IPC: G01S13/95
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a weather radar device for predicting such a weather phenomenon as micro burst at an early stage. SOLUTION: A radar transmission/reception part 402 acquires an echo intensity distribution using a mm wave. By using the mm wave, an echo intensity containing an ice crystal that cannot be detected by a cm wave can be measured. A signal processing part 4 detects the drop of a cell inside a cumulonimbus based on the echo intensity distribution at a drop detection processing part 32. A microburst and thunder are generated when the cell drops closer to the ground. An altitude detection processing part 34 detects that the cell drops at a warning altitude regarding the occurrence of such a weather phenomenon, thus predicting the weather phenomenon by a weather phenomenon prediction processing part 36.  Also, by using a mm wave for detecting an ice crystal, the threshold of the altitude in the altitude detection processing part 34 can be set at a high position-where the ice crystal exists instead of a low position where a water fall particle is generated.

Abstract: PURPOSE:To provide the cleaning device for bathtub hot water capable of detecting a waterless state when a circulating pump runs idle by a simple mechanism free from malfunctions. CONSTITUTION:The circulating pump 15 and/or a heater tank 16 are formed as a tank 10 for detection of the absence of the water. This tank is equipped with a tank weight detector 11 having a weight detecting element such as, for example, a pressure sensitive element.

IPC: H01J29/87
Filed: 1987-09-30
Abstract: PURPOSE:To maintain quality of explosion prevention and reduce the production cost by furnishing an interposition between a panel and an explosion preventive band. CONSTITUTION:Between an explosion preventive band 5 and the peripheral wall of a panel 2 an interposition 10 is arranged in a recess on the seal surface 2b side below a mold match line 2a and at a corner of the panel 2. This interposition 10 consists, for ex., of aluminum tape of 0.3mm thick and 8mm wide, narrower than the width of the explosion preventive band 5 which is 35mm. Thus the fastening force of the band 5 does not concentrate on the mold match line 2a, and the fastening force will thus have uniform distribution. Thereby the quality of explosion prevention can be maintained, and cost suppression attained because of saving resources.
