Title: Orienting film forming device for liquid crystal cell
Inventor: NAKAMURA SHINJI
IPC: G02F1/1337
Filed: 1989-09-19
Abstract: PURPOSE:To preclude a dielectric breakdown and the sticking of foreign matter due to the accumulation of static electricity and to improve the manufacture yield of liquid crystal cells by forming rubbing cloth of a conductive material, adhering this rubbing cloth to the outer periphery of a roller with a conductive adhesive material, and grounding the roller where the rubbing cloth is adhered through a resistor. CONSTITUTION:While the roller 2 wound with the rubbing cloth 8 is pressed against the surface of a transparent substrate 1 as shown by the arrow, the roller 2 or a stage 5 is moved. Consequently, the surface of an orienting film 1' on the transparent substrate 1 oriented and liquid crystal which is charged between substrates is oriented by this orienting film. At this time, the rubbing cloth 8 and its adhesive material 9 are conductive, so static electricity generated between the rubbing cloth 8 and orienting film 1' is not accumulated. Further, the roller 2 is grounded through the series circuit of a bearing plate 4 and a resistor 7 with a specific resistance value, so an excessive current due to the static electricity never flows through the surface of the substrate. Consequently, the liquid crystal orienting film is not broken electrostatically and the manufacture yield of liquid crystal cells can be improved.

Title: Recorder
Inventor: HOSAKA YASUO
IPC: B41J2/175
Filed: 1987-09-28
Abstract: PURPOSE:To prevent the clogging of ink in a nozzle part, by a construction wherein a semipermeable membrane is provided on a side wall of a nozzle and one surface of the semipermeable membrane is abutted against a liquid including an ink solvent. CONSTITUTION:On a head substrate 1, an ink container 2 and nozzles 3 are formed as an integral part. On the back surface of the nozzle part, a support part 13 in which a clogging-preventive semipermeable membrane is embedded and an ink flow path 14 are provided. During the stop of recording, an ink is isolated from an ink solvent contained in a container 4 by the semipermeable membrane; thus, an osmotic pressure does not exist if the both materials have a small difference in ion concentration etc., and the possibility that the ink solvent is infiltrated in the ink and a dye, drying inhibitor, impurity ion, etc. in the ink pass through the semipermeable membrane is eliminated. If a head action has been brought to a stop for a long time, the ink solvent is evaporated from orifices 23 at the tip ends of the nozzles, and the concentration of the ink is increased at the tip end parts of the nozzles. Thus, an osmotic pressure is generated between the ink and the ink solvent, and the ink solvent 22 is transferred into the nozzles through the semipermeable membrane 13 to decrease the ink concentration to a normal concentration. In this manner, the solidification or clogging of the ink in the nozzles can be eliminated.

Title: System for discriminating polarity of trunk line of trunk central office line
Inventor: YAMADA YUICHI
IPC: H04Q3/42
Filed: 1985-10-28
Abstract: PURPOSE:To prevent trunk line blocking due to reversing by monitoring the time to arrival of a ringing signal after detection of inversion if reversing is performed erroneously in the terminal processing of a trunk line circuit. CONSTITUTION:If reversing occurs, a polarity detecting circuit 1 sets a polarity detection signal (b) to the high level normally. Though a time limit monitor circuit 5 starts to monitor the time when the polarity detection signal (b) rises to the high level, a time-up signal is outputted to a holding circuit 4 after a prescribed time because the ringing signal does not come. The holding circuit 4 takes in the polarity detection signal (b) (high level) in response to this signal and sets the Q output to the high level. As the result, a logic circuit 3 sets temporarily a polarity scan signal (e) to the high level but sets it to the low level quickly and holds this state. Thus, the private branch exchange side discriminates that this polarity inversion is not caused by incoming, and this trunk line circuit is not blocked.

CONSTITUTION:When a throttle valve 11 is in its idle opening, to the intake air of an engine 12 being in a small quantity is supplied the supplementary air under low pressure through an air control valve 23, which is caused to open and close providing for a long valve opening period, and, at the same time, the fuel in a quantity corresponding to the total air quantity as above is supplied through a fuel passage 4 and a compensating fuel passage 8. Hereupon, when the throttle valve 11 is caused to open a little, the air pressure acting upon the inlet of the air control valve 23 is caused to rise a little, and thereby, the valve opening period of the air control valve 23 is shortened a little, while, the valve opening period of a fuel control valve 10 is lengthened in response to the total air quantity increased. Hereby, in an operating range where the intake-air quantity is small, is introduced the supplementary air in a quantity nearly proportional to the intake-air quantity, and moreover, the supplementary air is controlled in relation to the fuel.
