Abstract: PURPOSE: To obtain a tar acid useful as a raw material for a resin, etc., in high purity, from a tar oil, by bringing a tar acid salt or a crude tar acid into contact with a gas containing oxygen as a specific temperature, and distilling the crude tar acid under reduced pressure in a distillation column at a specific temperature.  
     CONSTITUTION: A tar light oil given by the distillation of coal tar or a tar oil, e.g. carbor oil, is extracted with an aqueous alkaline, e.g. caustic soda, to prepare a tar acid salt, and the resultant salt is decomposed with an acidic substance, e.g. gaseous carbon dioxide or sulfuric acid, to prepare a crude tar acid. In the process, the tar acid salt or crude tar acid is brought into contact with a gas containing oxygen at 40W100°C, preferably at 60W90°C. The crude tar acid thus obtained is distilled under reduced pressure in a distillation column in which the highest temperature, i.e. bottom temperature, is lower than 200°C to give a tar acid containing small amounts of impurities, e.g. a sulphur compound, and having improved smell, etc., e.g. phenol, a cresol or a xylenol.

Title: Charged program distribution system
Inventor: FUJII TOSHIAKI
IPC: H04N7/16
Filed: 1989-01-27
Abstract: PURPOSE:To prevent charging due to mis-operation by providing a no-charge viewing time displaying all charged programs of a charged program group on split screens simultaneously upon the receipt of a channel request signal of the charged program group at the terminal controller. CONSTITUTION:To select a desired viewing program, a key pad 320 is used to send a channel number to a terminal controller 310. The terminal controller 310 converts a channel number into a channel request signal and decodes it to discriminate whether the program is a charged program or a no-charge program. When the program of the channel number is the charged program, the terminal controller 310 displays the pattern of the charged program guide after a prescribed time in the timing of a timer. In order to view a desired program of the video program group with a charge, the key pad 320 is depressed on the desired program number. Thus, the charged programs able to be selected are operated by one operation in the case of viewing the charged program.

Filed: 1989-01-28
Abstract: PURPOSE:To improve receiving sensitivity and detecting efficiency by providing a plurality of band-pass filters having frequency band regions not overlapped with each other, and setting a threshold value low for detecting an object to be detected in a long distance. CONSTITUTION:A receiving signal from an antenna 5 is, input through a mixer 7 to a first and a second signal processing circuits 9 and 10. A signal in a short distance is extracted by a first band-pass filter, and discriminated at 9b on the basis of a threshold value preliminarily set in a first threshold value generator circuit 9c not to be influenced by noises. The pulse signal is counted at 9d and sent to a processing circuit 11. The same procedure is carried out in the circuit 10, but a threshold value preliminarily set at 10c is set lower than the value set in the circuit 9c since the noises are removed by a second band-pass filter 10a and a reflecting signal of an object 6 to be detected in a long distance is relatively at a low level. The distance and relative velocity to the object 6 is calculated in the circuit 11.

Title: Method for manufacturing halogen lamp
Inventor: FUCHI TSUTOMU
IPC: H01K3/22
Filed: 1983-02-04
Abstract: PURPOSE:To obtain a halogen lamp of long life, by filling in the glass bulb a gas including an inert gas and phosphine during the evacuation process, so that the oxide produced may be reduced by the phosphine. CONSTITUTION:As the gas to be filled in the glass bulb during the evacuation process, an inert gas of nitrogen, argon, or mixture of them with a small amount of phosphine is used. The phosphine, when the filament in the glass bulb is heated for illuminating, easily resolves into PH and hydrogen by the heat. The PH can reduce the tungsten oxide produced since the PH becomes phosphorus oxide taking the oxygen from the tungsten oxide. The amount of the phosphine to be added to the inert gas should be between 0.1% and 3% by volume.
