Inventor: BERUNTO FUPUFUAA
IPC: C08G73/00
Filed: 1987-05-06
Abstract: Described are polyamic acids, at least 50 mole-% of which are comprised of recurrent units corresponding to the general formula I: <IMAGE>  (I)  wherein, R1 is a mono-, di-, tri- or tetranuclear aromatic group and X is O, S, CO, SO2 or CR2R3, each one of R2 and R3 being H or CH3. A polyamic acid of the present invention, in the form of a solution, is applied to a substrate, for example, a semiconductor device, to form a protective layer thereon, and is converted into polyimide by heating. As against comparable compounds known in the art, the polyamic acids of the present invention are distinguished by a lower inherent viscosity at an unchanged molecular weight and, consequently, by an improved processability at an equally good thermal stability.

Filed: 1985-05-23
Abstract: PURPOSE:To form an image in a short time and improve image stability and storage stability before development by forming a photosensitive layer contg. photosensitive silver halide together with a specified compound. CONSTITUTION:The photosensitive layer formed on the support contains a photosensitive silver halide emulsion and one of compounds represented by formula (I) in which Q is a group having at least one S atom and one N atom and a pKa of >=6, n and m are each an integer for balancing electric charges; and R<0> is H of an org. group. The compound of formula (I) is, preferably, added to the photosensitive layer, by dissolving it in water, ethanol, or the like, and it may be added to the coating soln. by separating them into the acid (R<0>-CidenticalC- CO2H) and the base Q.

Title: Dialing restriction system in portable telephone system
Inventor: MAEDA JUNJI
IPC: H04W48/12
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To allow the system to automatically stop dialing by a portable telephone terminal, when it is resident in a radio communication inhibit area by detecting it that the portable telephone terminal enters the radio communication inhibited area and turning off automatically power supply to a transmission section of the portable telephone terminal through the use of a pseudo-control channel. SOLUTION: A control section 37 of an HP 31 monitors an on/off state of a SW of a switch section 36 at all times to store the state to a storage section 38. When the SW is closed manually and the HP 31 enters a radio communication inhibit area and passes a transmission area of a frequency f1 to a frequency f2 in this order, a reception section 34 informs the reception in the order of a f1 pseudo-control channel signal to a f2 pseudo control channel signal to the control section 37, the control section 37 recognizes the closed state of the SW from the storage section 38 and sends a control signal to the switch section 36, which applies on off control to the SW. Then the SW interrupts power supply to a transmission section 33.  When the HP 31 enters the radio communication inhibited area, while manually opening the SW, the control section 37 recognizes the power off state, based on the contents stored in the storage section 38 and controls the SW so that the power off state continues.

Title: Treatment of oxidation exhaust gas from refining furnace
Inventor: ECHIGOYA TAKUMI
IPC: C01B17/50
Filed: 1979-08-29
Abstract: PURPOSE: To use effectively and stably oxidation exhaust gas whose SO 2  concn. is low and changes from a refining furnace in the manufacture of sulfuric acid by feeding the exhaust gas to a smelting furnace and introducing it into a sulfuric acid manufacturing plant together with exhaust gas from a continuously smelting plant.  
     CONSTITUTION: When a refining furnace is changed over from keeping warmth to oxidation, damper 1 is closed and damper 2 is opened. Next, on the basis of a calculated value air flow rate indication regulator 5 is regulated. For example, the vol. of air fed to the burner of the smelting furnace of a continuously smelting plant as secondary air is reduced by the content of O 2  in oxidation exhaust gas exhausted from the refining furnace and enrched with oxygen to 21% O 2  concn. After finishing the oxidation process damper 2 is closed, damper 1 is opened, and regulator 5 and oxygen flow rate indication regulator 6 are regulated to return the air vol. to the original value. When the dampers are opened or closed, insufficient or excessive oxidation is caused in a moment, yet no problem occurs in operation. The above- mentioned operation is carried out in the operation control room of the smelting plant.
