IPC: B07B11/00
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide an air classifier in which while the lower limit of the particle diameter of separated particles is prevented from increasing, sharp classification is secured when increasing the throughput of powder materials. SOLUTION: A guide plate 9 forming a classifying chamber 15 undergoes rotary driving by a motor 13. As a result, a turning vortex of powder materials above the rotated guide plate 9 undergoes speed increasing and they are fed into the classifying chamber 15 through a clearance 10.

Title: Pulse stretch circuit

IPC: H03K5/04
Filed: 1984-02-29
Abstract: PURPOSE:To obtain a pulse stretch circuit for facilitating visual confirmation, discrimination and judgement, by enlarging the receiving pulse width of a radar reflected signal. CONSTITUTION:With due regard to the timewise relation of the signal wave form of a specific one low video signal S1 in each circuit, the output signal wave form of a monostable multivibrator 3 rises directly before that of a delay circuit falls. Therefore, the output wave form of the output terminal T3 of an OR circuit 4 outputs a pulse signal, which has a time width from the rising of a pulse signal shown by D to the falling of a signal shown C, as shown by E. In this case, because the delay circuit 2 is interposed, the characteristic of the delay time td of the delay circuit 2 is put to practical use and the timewise relation of two pulse signal wave forms inputted to the OR circuit 4 is properly selected to prevent the generation of trouble. As the delay element of the delay circuit 2, an inherent delay time characteristic possessed by IC is utilized to enable said delay element to also have a function as a pulse stretch circuit.

IPC: G02F1/1337
Filed: 1984-02-27
Abstract: PURPOSE:To reduce remarkably orientation disorder generated on a display electrode by an influence of a projecting part, by rubbing an orientation of the surface of an uneven substrate to an active element side from the display electrode side in a pair of active elements and the display electrode. CONSTITUTION:An arrow in the figure indicates a rubbing direction, and a pair of active elements 1 and a display electrode 2 are rubbed from a recessed part to a projecting part, namely, in the direction of the active elements 1 from the display electrode 2, with a cloth or a cotton textile. When rubbing is executed in this way, the display electrode is not stroked down between a pair of active elements 1 and the display electrode 2, therefore, orientation disorder on the display electrode 2, which has been generated in a conventional rubbing direction is not generated, and a drop of a display performance in case a voltage is applied does not occur. Also, the active element 1 comes to generate orientation disorder 8 at the left-hand adjacent display electrode side, but this disorder 8 is generated in a part of a gap 5 of the electrode. Accordingly, even if the orientation disorder 8 is generated, no voltage is applied to the gap 5, therefore, a drop of a display performance in case a voltage is applied does not occur. Also, as for an influence on the display electrode 2, it is scarcely affected by the right-hand adjacent active element, because the gap 5 becomes hollow as compared with the display electrode 2.
