Title: Recovery of quinoline
Inventor: KAGEYAMA KENJI
IPC: C07D215/04
Filed: 1985-01-09
Abstract: PURPOSE:To recover quinoline from a quinoline-containing fraction produced by the distillation of coal tar, economically, by distilling out methylnaphthalene from the fraction by the azeotropic distillation with a specific amount of a polyalkylene glycol, and carrying out the superfractionation of the bottom oil. CONSTITUTION:A quinoline-containing fraction K produced by the distillation of coal tar is added with 0.2-5 times weight of a polyalkylene glycol L (e.g. diethylene glycol), and distilled to remove the methylnaphthalene having boiling point close to quinoline from said fraction K by azeotropic distillation 4. A bottom oil 5 almost free from methylnaphthalene can be obtained by this process. The bottom oil 5 is subjected to the superfractionation 14 to obtain high- purity quinoline 18 with simple process in high yield. When the concentrated quinoline fraction is collected in the above superfractionation 14 and subjected again to the superfractionation, quinoline having higher purity can be recovered.

Title: Optical card
Inventor: SATO NAOYUKI
IPC: G11B7/24085
Filed: 1990-01-11
Abstract: PURPOSE:To accurately search for the data in an optical card by recording the position of the least significant bit among the data showing the positions of individual data recording regions at the position near the center of the laser beam within a laser beam irradiation range from the position of the most significant bit. CONSTITUTION:A track number showing pattern 3 is arranged so that the LSB (least significant bit) is located at the center of illumination light 8, that is, the position max. in quantity of light and having high resolving power and goes to a position of low resolving power where the end of the illumination light, that is, the quantity of light successively becomes min. as a bit transfers from the LSB to the MSB (most significant bit). The unchanged part on a ring where luminous intensity does not almost change even when the distance between a condensing lens 19 and an optical card 23 is changed is generated in an illumination region and the change of luminous intensity becomes reverse on the inside and outside of the unchanged part by the change of the focus state of the condensing lens 19. That is, when the optical card 23 approaches the condensing lens 19 from the focal position of the condensing lens 19, luminous intensity increases as compared with that at the time of focusing on the inside across the unchanged part but decreases on the outside.

Title: Electric discharge machine
Inventor: KONNO MASANORI
IPC: B23H1/02
Filed: 1984-01-12
Abstract: PURPOSE:To make it possible to adjust the time width of an initially set machining pulse in accordance with variations in the recovering time of insulation of the electrode gap, by driving a switching elememt in accordance with an signal from a signal generating means and an output signal from a comparing and computing means. CONSTITUTION:When a voltage is applied across the electrode gap 13 from a machining power source 5, a voltage VC is produced across a resistance in accordance the impedance of the gap, and is compared with a set voltage VO by a comparator 22 which issues an H-level signal if VG>VO. Further, arc discharge takes place when the electrode gap 13 is narrowed, and the voltage of the resistance 1 due to the current is detected by menas of a detecting device 15. Accordingly, a monostable multivibrator 17 issues a pulse signal having an on- time time width and a monostable multivibrator 19 issues a pulse signal having an off-time time width to reset a flip-flop 25 to open a switching element 7. However, an L-level signal from an inverter 27 is added to an AND 23 together with the H-level signal from the comparator 22 so that the off-time time width of the machining pulse is actually obtained. Accordingly, the off-time time width of the machining pulse may be automatically adjusted.

Title: Toner concentration controller for zerographic copier
Inventor: AKIYAMA MITSUO
IPC: G03G15/08
Filed: 1978-01-17
Abstract: PURPOSE:To accurately detect the patch image upon a photosensitive drum with the use of a small patch by using the operations of a microswitch, which is operated by the cam mounted in a suitable position of a carriage, as the start signals. CONSTITUTION:A carriage 1 is equipped at its leading or trailing end with a patch 3 having a preset density and at a suitable position with a cam 20. There is mounted on a copier a microswitch 21 which is operated by the movement of the cam 20. Thus, since the positional relationship between the patch 3 and the cam 2 is fixed, the operating point of the microswitch 21 by the cam 20 and the patch image moving position on the photosensitive drum are automatically determined. Upon detection of the patch image on the photosensitive drum, therefore, the influence from the positional shift of the start and stop of the carriage can be eliminated so that the accuracy in locating the patch image can be improved.

At the time when the state of combustion becomes a stationary state, e.g. 30 minutes later, the area of the exhaust passage in the exhaust pipe 9 is narrowed by the damper 10 and thereby the area of the exhaust passage is controlled to be small. Accordingly, it is possible to attain safety by lowering the value of CO/CO2 in the initial stage of the start of combustion and to increase a heat exchange efficiency even after the shift to stationary combustion.

Accordingly, in an initial stage of feeding of a fluid, electromagnetic valves 9 1 , 10 1  are opened so that the differential flow meter 2 1 , which is used to measure flow rates in a minimum flow rate range, is opened. When the flow rate is gradually increased to reach such a level that cannot be measured by the flow meter 2 1 , electromagnetic valves 9 2 , 10 2  are opened to render the differential flow meter 2 2  operable while closing the electromagnetic valves 9 1 , 10 1 . The flow rate measurement is then continuously carried out in the above-described manner using a suitable one of the differential flow meters 2 1 , 2 2 ,.... A measurement value thus obtained is then compared with a measurement value displayed in the reference flow meter 1, through an operational circuit 12 so as to be corrected. Thus, the flow rate measuring accuracy can be improved.

Abstract: A portable duplex radio telephone system includes at least one base station transmitter having a predetermined base transmission range, and a plurality of portable or mobile units each having a predetermined portable maximum transmission range predeterminately shorter than the base transmission range. Satellite receivers are deployed about the base station within the base station transmission range for receiving transmissions from the portable units. The base station transmitter transmits signals on a signalling channel and on at least one communications channel. Each transmitter signalling and communications channel has a frequency that is paired or associated with a receiving frequency of the satellite receivers. In a multiple base station system, the portable receiver has means for scanning the base station transmitter signalling frequencies and for tuning the portable transmitter to the signalling frequency associated with the frequency of the strongest signalling signal received from the base transmitter. When communication is initiated, the portable transmitter and receiver are automatically retuned to one of the communications channels as determined by the strongest signalling frequency received by the portable receiver and by channel availability. Means are also provided in the system to continuously locate a portable unit and switch the operating frequency thereof as the portable unit moves between base station transmitter coverage areas. Further means are provided to automatically reduce the output power of each portable transmitter to the minimum level required for satisfactory communications in order to reduce battery drain and the interference caused by the portable transmitters.
