Title: Clogging prevention device for ink jet recording head
Inventor: NISHIKAWA MASAHARU
IPC: B41J2/165
Filed: 1985-02-27
Abstract: PURPOSE:To prevent clogging of an ink jet recording head by adhering a continuous gas-permeable porous member impregnated with low volatility solvent on the outer side of a small aperture for spraying ink droplets and sealing them together. CONSTITUTION:If a recording head 10 stops facing a capping head 30, a small aperture in a plate-like member 14 located at the tip of the recording head 10 adheres to a projection 32a of a porous member 32 exposed from a case 31 of the capping head 30 and is hermetically sealed by the porous member 32 and low volatility solvent impregnated in the porous member 32. That is, the evaporation of liquid ink 11 in the recording head 10 through the small aperture 17 is prevented by the blocking of the small aperture 17 by adhering porous member 32 impregnated with low volatility solvent. Thus the clogging of the small aperture with ink can be prevented because ink evaporation is prevented during the non-recording by an ink jet recording head.

Abstract: PURPOSE: To remarkably reduce a pure water-producing cost, by measuring the collection rate and the electric conductivity of industrial water to be brought  into contact with ion-exchange resin, and determining the amount of a regenerating agent for the ion-exchange resin from the measured values.  
     CONSTITUTION: A collection rate U of industrial water is calculated by a water meter 22, and the electric conductivity K of the collected industrial water is measured by a liquid electric conductimeter 23. The necessary amount of each of a 35% HCl water solution and a 25% NaOH water solution as regenerating agents for cation-exchange resin and anion-exchange resin, respectively, is computed. In response to the computed necessary amount of each regenerating  agent, the 35% HCl water solution from a line 24 and a 25% NaOH water  solution from a line 25 are fed along a line 28 and a line 29 by pump strokes 26  and 27 controlled by air pressure or the like.

Title: Automatic carrier
Inventor: YOSHIIE HIDEO
IPC: G05D1/02
Filed: 1989-02-20
Abstract: PURPOSE:To enable each carrier to operate efficiently by allowing the carrier to receive a signal from another carrier which travels on the same travel line and approaches, to decides priority in comparing with its own signal, and to perform backing processing at need. CONSTITUTION:When two carriers 1a and 1b face each other on the same travel line 4, signal outputted by transmitting means 8a and 8b of the carriers 1a and 1b are received by receiving means 9a and 9b of the opposite carriers. The priority levels of travel time signals and stop time signals of the carriers 1a and 1b are predetermined, so when the priority of one carrier is lower than that of the other carrier, the former carrier backs to the nearest stand-by path and restarts traveling a certain time later. Consequently, the interference between the carries can freely be evaded, and the operation efficiency of the carriers is improved.

IPC: G04G99/00
Filed: 1986-02-25
Abstract: PURPOSE:To effectively utilize a display by so constructing a digital clock for car that the transfer data of a microcomputer mounted on a vehicle are displayed. CONSTITUTION:A time measuring counter 2 receives the original oscillation signals from an oscillator 1 to form time measuring data and, after corrected by a measured time correcting circuit 7, outputs the data to a display changeover circuit 3. On the other hand, a serial data register 9 holds the data serially transferred from a microcomputer 10 and outputs the data to the circuit 3 based on the state signals from a sensor 11. The circuit 3 selects either of the data of the counter 2 and the data of the register 9 by the output of a changeover signal generating circuit 8 and outputs the selected data to a decoder circuit 4. The circuit 4 converts the received data to those corresponding to display signals and transfers them to a display driver 5. The driver 5 drives the display elements of a display 6. When a changeover switch 8a is turned ON, a changeover signal is generated 8, the selection of the time measuring data is stopped in the circuit 3 and the data of the register 9 are selected to be displayed 6.

Abstract: PURPOSE:To improve the sensitivity of signal detection to a signal having a long pulse width in an object pulse width range by providing plural signal detection circuits that are different in video band width and an OR circuit which synthesizes the outputs of plural signal detection circuits to output the result. CONSTITUTION:A signal detection circuit 101 out of plural signal detection circuits 101 and 102 that are different in video band width sets a wide video band width in accordance with the band of a minimum pulse width signal as the object, and the signal detection circuit 102 sets a narrow video band width in accordance with the band of a maximum pulse width signal as the object. An OR circuit 103 synthesizes the outputs of signal detection circuits 101 and 102 to output the result. Thus, the sensitivity to the signal having a long pulse width in the object pulse width range is improved when the pulse signal having a pulse width in a wide range is detected as the object.

Abstract: PURPOSE:To reduce the difference in recording density generated by every group by sliding boundaries of groups of needle-shaped electrodes in the scanning direction in relation to the center of control electrodes. CONSTITUTION:Multineedle electrode groups 2 prepared by providing the needle- shaped electrodes E in parallel are put together by several units to be divided into a plurality of groups G1, G2, G3,... and connected. On the other hand, the control electrodes 3a, 3b, 3c,... are arranged in such a manner that the central position P thereof in the direction of parallel provision of the electrode groups 2 is slided to the left in the figure by a distance R from each boundary position Q of the groups G1, G2, G3,.... The recording density obtained by impressing voltage each of the electrodes thus arranged is not conspicuous almost at all for its difference, though the density is somewhat lowered in parts corresponding to the vicinity of boundaries of groups G1, G2, G3,... of the needle-shaped electrodes. Thus, the density forms a curve S'T' and the difference DELTAD' in density turns very small in comparison with the difference DELTAD in density in the existing device.

Title: Piezoelectric type speaker
Inventor: NOMURA HIROO
IPC: H04R17/00
Filed: 1978-04-06
Abstract: PURPOSE:To simplify construction and yet enable a speaker of extra thin type of low power consumption by making use of a thin film piezoelectric element lamination-formed with a diaphragm which becomes the substrate for the thin film element. CONSTITUTION:A thin plate of metal is used for a diaphragm 7 and also serves as an electrode. A ZnO thin film 8 which has piezoelectric characteristics of, e.g., several 10mum is deposited through vapor deposition or sputtering on this diaphragm. Further an electrode thin film 9 is deposited on this thin film 8. The sound is produced by applying audio voltage between the diaphragm 7 serving also as the electrode and the thin film electrode 8 thereby causing flexural vibrations in the diaphragm. Namely, the piezoelectric thin film elongates or contracts in the face direction according to the application directions and intensities of the voltage and therefore the diaphragm in close contact with the thin film causes flexural motion so as to be able to follow-up this change and this is propagated to air, thus producing sound waves. Thereby, the speaker of extra thin type may be obtained.
