  • Patent number: 5532372
    Abstract: An imide compound of the formula: ##STR1## wherein Z is a group of the formula: ##STR2## in which the substituents are defined herein, and n is an integer of 0 to 1;D is a group of the formula:--(CH.sub.2).sub.p --A--(CH.sub.2).sub.q --in which A is a non-aromatic hydrocarbon ring optionally bridged with a lower alkylene group or an oxygen atom, said non-aromatic hydrocarbon ring and said lower alkylene group being each optionally substituted with at least one lower alkyl, and p and q are each an integer of 0, 1 or 2; andAr is an aromatic group, a heterocyclic aromatic group, a benzoyl group, a phenoxy group or a phenylthio group and G is >N--, >CH-- or >COH-- or Ar is a biphenylmethylidene group and G is >C.dbd., all of the above groups being each optionally substituted with at least one of lower alkyl, lower alkoxy and halogen; and its acid addition salts, useful as an antipsycotic agent.

  • Patent number: 5325112
    Abstract: An ink jet recording apparatus of the continuous jet type and an automatic ink jet jetting axis adjusting method of the same wherein the position of an ink jet jetting axis or nozzle axis can automatically be adjusted to an optimum position by a deflecting electric field are disclosed. When a carriage is at its home position, jetting of ink from a nozzle is started, and an MPU changes over a change-over switch to a test signal generator side. The test signal generator generates a test signal, which is a sum of an amplified recording signal and a bias potential outputted from a bias power source, and applies the test signal to a controlling electrode. The MPU checks an output of a current detector (jet current) based on charged ink drops caught by a conductive drop catcher to discriminate the positional relationship between an ink jet jetting axis and a knife edge. The MPU then changes the bias potential of the bias power source in accordance with a result of the discrimination.

  • Patent number: 4085408
    Abstract: A liquid jet recording apparatus which effects non-impact recording by the application of a jet of liquid ink to a recording medium. The liquid jet recording apparatus includes means for stabilizing the frequency of droplets of the liquid ink jetted from the exit end of a nozzle and also for improving the droplet frequency to a relatively high value. The provision of this means is advantageous in that a line of uniform line width and of uniform ink deposit can be drawn thereby. In addition, means is disclosed to eliminate the use of electrical parts which are expensive and require a relatively high voltage withstanding characteristic.
