Title: Method for regenerating catalyst for production of unsaturated diester
Inventor: FUJIWARA HIDEETSU
IPC: C07C67/055
Filed: 1990-03-15
Abstract: PURPOSE:To nearly perfectly restore the activity of a catalyst and to prolong the service life by subjecting the deactivated catalyst to halogenation treatment as well as oxidation treatment and then subjecting the catalyst to reduction treatment. CONSTITUTION:When a catalyst for production of unsatd. diester is deactivated, this deactivated catalyst is subjected to oxidation treatment with a gas contg. oxygen at 100-600 deg.C to burn away deposits such as a high b.p. substance and a carbonaceous substance and to oxidize the catalytic component such as Pd. At the same time, the catalyst is brought into contact with a gas contg. a halogen compd. such as a Cl or F compd. and steam to convert part of the catalyst into a halogen compd. The catalyst is then subjected to reduction treatment at 100-600 deg.C in a flow of a reducing gas such as H2 or CO or vapor of an org. compd. such as methanol. The deactivated catalyst is regenerated to such a degree that it has high activity and a long service life comparable to those of a fresh catalyst.

Title: Signal processing system of gas sensor
Inventor: SUGIYAMA IWAO
IPC: G01N21/39
Filed: 1986-03-20
Abstract: PURPOSE:To achieve a higher sensitivity of a gas sensor, by performing a signal processing to make a primary differentiation signal overlap a secondary differentiation signal of an absorption line of a gas sensor using an infrared semiconductor laser to remove effect of an absorption line of a non-measuring gas other than a gas to be measured. CONSTITUTION:A signal waveform detected with a detection element 2 of a laser light 1 passing through the atmosphere 5 is subjected to a primary differentiation with a lock-in amplifier 6' and signal waveforms detected with detection elements 2 and 2' are subjected to a secondary differentiation with a lock-in amplifier 6'' to be treated with a signal processor 7. A signal curve n0 actually obtained presents the combination of n1 (signal curve of a gas to be measured and n2 (signal curve of a non-measuring gas to be measured). Therefore, the intensity of the signal contains error equivalent to d0' due to effect of a non- measuring gas at the center omega0 of absorption spectrum of the gas being measured. The error value d0' can be calculated based on a signal d0 and thus, a correct detection value can be obtained by a processing to subtract the signal by the error d0 from the absorption spectrum omega0.

The manganese compd. is easily removable by a neutralization treatment by a soln. contg. a reducing agent. This reducing agent includes a hydroxyl amine sulfate, etc., and the soln. prepd. by adding an acid thereto is preferably used. For example, a polyimide film is irradiated with the excimer laser beam, by which the film is partly bored. Next, the film is subjected to an imersion treatment in an aq. alkaline potassium permanganate soln. and neutralization treatment. The processing residues observed around the processed parts of the polyamide are removed after the treatment. As a result, the accuracy of laser beam processing of the heat resistant resin, such as small-diameter boring in the production stages for the wiring boards and the reliability of the processed products are improved.

Title: Memory dump system
Inventor: NAKADA AKIHIKO
IPC: G06F11/34
Filed: 1987-03-17
Abstract: PURPOSE:To reduce the capacity of an external medium by providing the title system with the fault code of a generated fault and an information extracting descripter table describing a memory block including necessary information for the fault and outputting information in a memory to the external medium on the basis of the description table. CONSTITUTION:When a dump routine is started under a certain condition, the descripter table 2 is read out by a magnetic disk and a corresponding descripter 20 is extracted from the table 2 by using a fault code generated from a computer system as a key. A dump routine extracts the address of a memory block to be adopted and its length from a memory block field 4 defined in the descripter 20 and outputs fault information to the magnetic disk on the basis of extracted information. The dump routine repeats said operation until a memory block field 4 disappears. Since the minimum information required for the generated fault can be outputted to the external, the capacity of the external medium device can be reduced.

Title: Defect detector
Inventor: KAMIYA KAZUAKI
IPC: G01N21/89
Filed: 1991-03-27
Abstract: PURPOSE:To enable the changing of a skew angle simply by varying an angle of a roller of a defect detector by providing a mechanism which advances an object to be inspected radially rotating it in a circumferential direction thereof by a skew feeding using a semi-spherical conveying roller to set a ratio between a rotational speed and a conveying speed thereof. CONSTITUTION:A conveying roller 9 comprises a semi-spherical roller section and a conveying drive shaft and the roller 9 is held with a roller holder 10. A roller angle changing mechanism 11 tilts the holder 10 to an angle corresponding to a skew angle. Two rollers 9 are set opposed to each other and inclined to an angle corresponding to a screw angle while a skew feeding of the pipe- shaped object 5 to be inspected is performed when the pipe-shaped object 5 to be inspected is placed to turn. In addition, when the skew angle is changed, the holder 10 is turned with the mechanism 11 to change angles of all the rollers 9 uniformly. In this case, since the roller 9 is semi-spherical, the ratio between rotational speed and the conveying speed can be changed freely without varying a contact state with the object 5 to be inspected.

Filed: 1992-03-19
Abstract: PURPOSE:To apply interlocking control to terminal equipment by providing a processing table specifying the relation with a control output to be generated from a terminal equipment interlockingly and inputting directly a control signal to a transmission controller. CONSTITUTION:A transmission controller 2 monitors and controls plural installation equipment terminal equipment 1 in each section range in a building.

Then the controller 2 is provided with a processing table 4 specifying the relation between a control signal input and a control output to be generated by terminal equipment in cooperation under the control of the controller 2 in response to the control signal input. Then the interlocking control between the terminal equipment 1 connected directly to the controller 2 is executed by having only to input the control signal to the controller 2 installed in its area. Thus, the interlocking control by the terminal equipment 1 under the control of the controller 2 is implemented independently of the controller 2 of other area by directly inputting a control signal to the controller 2.
