Title: Ink supply method in ink jet printer, printing head device and ink jet printer
Inventor: HAYAMIZU TSUKASA
IPC: B41J2/01
Filed: 1992-09-17
Abstract: PURPOSE:To simplify a structure, to stabilize the contact of a nozzle group with heating elements and to enhance the reliability of the flight of ink droplets by attracting a nozzle film to the heating elements by an attraction means and finely vibrating the nozzle film by heat energy to guide ink to nozzles. CONSTITUTION:When ink is supplied to an ink sump part 23A and a nozzle film 10 is attracted by a permanent magnet 25, a nozzle group 12 is contacted with heating elements 21. When the respective dots of the heating elements 21 are successively driven one by one in this state, the nozzle film 10 and the heating elements 11 instantaneously become a non-contact state from the contract state by generation of heat and ink flows to the peripheries of the heating elements 21 to enter nozzles 11. At the same time, the ink in the nozzles 11 bumps by heat energy to be injected as ink droplets. In this case, since the dots of the heating elements are heated one by one, the pressure generated by heat and the contact pressure with the head can be properly set.
Patent JP-H09133718-A (JP)
Title: Phase detector
Inventor: YOSHINO TERUO
IPC: G01R25/00
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To correct a phase by the amplitude of an AC system voltage so as to properly detect a phase even when an accident occurs because when an accident occurs in the AC system during phase detection, the amplitude of the AC system becomes small and a phase error is increased. SOLUTION: When an accident occurs in an AC system, if the voltage of the AC system is reduced, the output of a normalization circuit 21 becomes small. Then, a phase difference operation value Δθis also reduced in proportion to the amplitude of the AC system voltage. When the phase signal Δθ becomes small, a change in the output of the integrating element of a filter circuit is also reduced and a change in the oscillation frequency of an oscillation circuit becomes small. Especially, when the AC system voltage is 0, no change occurs in the frequency of the oscillation circuit. Thus, in the condition of an AC system accident, no large change occurs in a detected phase from its previous phase.  Further, when the AC system accident is eliminated and the AC voltage is recovered, the output of the circuit 21 is returned to its original size and phase detection is performed in a state similar to a normal state.

Title: Adsorptive separation of para-xylene using tetralin desorbing agent
Inventor: HAAMAN EI JINEN
IPC: B01D15/00
Filed: 1989-11-07
Abstract: Para-xylene is separated from a feed mixture of C8 isomers of xylene and C9 aromatics by contacting the para-xylene-containing feed mixture with a crystalline aluminosilicate zeolite, e.g. an X or Y zeolite adsorbent having Group IA or IIA cations, e.g. barium and/or potassium, at exchangeable cationic sites. The para-xylene is selectively adsorbed onto the adsorbent. The non-adsorbed feed is then removed from the adsorbent and the para-xylene recovered from the resulting rich adsorbent by desorption with a desorbent comprising 1,2,3,4-tetrahydronaphthalene or an alkyl or dialkyl derivative of 1,2,3,4-tetrahydronaphthalene or mixtures thereof. The majority of the C9 aromatics and the xylene isomers are typically recovered in the raffinate and can be separated from the desorbent by fractionation of the raffinate and the recovered desorbent recycled to the process.

Abstract: PURPOSE:To enable patterns or the like to be preserved for a long time, by subjecting aluminum and an aluminum alloy to a primary alumite treatment, printing on the primary alumite-treated surface by using a non-conductive printing ink, subjecting the primary alumite-treated surface to a secondary alumite treatment, and dyeing the secondary alumite-treated surface.

In printing, characters, patterns or the like are formed on the primary alumite-treated surface by using a printing ink having excellent non-conductivity, while said ink is prepared by mixing a dye or pigment into a non-conductive vehicle. A secondary alumite treatment is conducted under the same conditions as for the primary alumite treatment. The alumite treatment is not performed on parts facing the patterns or the like, and a secondary alumite-treated surface grows in a raised state on the entire part of the primary alumite-treated surface except the patterns or the like, so that the patterns or the like are provided in a sunken state in the secondary alumite-treated surface.

Title: Vacuum pressure calibrator
Inventor: KAGIFUKU TATSUO
IPC: G01L21/00
Filed: 1988-11-18
Abstract: PURPOSE:To maintain a prescribed negative pressure by a method wherein a negative pressure generated in a piping for generating a reference vacuum pressure is measured to control a flow rate of a gas with a regulation of a flow regulating valve to enable a reduction in time for calibration work and a fine adjustment bidirectionally with a simple operation. CONSTITUTION:When air is supplied into a main piping 9 from a pressure air source 10, a flow velocity of air becomes higher when air passes through a jet pump 11 to cause a suction by a negative pressure on the side of a piping 3 for generating a reference vacuum pressure. The flow velocity changes during the passage through the pump by adjusting a flow rate of air flowing through the main piping 9 with a flow regulating valve 12 to vary the negative pressure generated in the piping 3. Then, a negative pressure generated in the piping 3 is measured with a reference instrument 1 and an air flow rate is controlled with the regulation of the valve 12 to obtain a prescribed negative pressure thereby enabling calibration of the instrument 1 to be calibrated.

IPC: F01L1/344
Filed: 1990-10-26
Abstract: PURPOSE:To downsize the outer diameter and to provide the required brake torque to a drum gear and operate it by providing a braking means which is used to give brake torque to the drum gear outside the ring gear with a cam shaft as a center. CONSTITUTION:A ring gear 13 is interposed between a timing pulley 7 and a cam shaft 1, and the timing pulley 7 and the cam shaft 1 are connected. An annular magnet 27 as a braking means is contained peripherally inside a brake plate 25. This magnet 27 is arranged at the position outside the ring gear 13 with the cam shaft 1 as a center. This arrangement allows the outer diameter of the whole device with the cam shaft 1 as a center to be downsized, resulting in improvement of mountability of the device itself onto the engine. A relatively small braking force generated by the magnet 27 can give the drum gear 20 the brake torque to resist the rotational force of the ring gear 13, leading to reduction of the power losses.

CONSTITUTION:When transmission data is not received from an earth satellite during the travel of a mobile body from an initial set position (reference position), the current position of the mobile body is obtained by a self-contained inertia navigation measurement section 5, and shown in a display section 12. In this case, when transmission data from three or more satellites satisfying a measurement condition with GPS navigation is received by a GPS receiving section 1, the current position of the mobile body is obtained by GPS navigation measurement section 2 and shown in the display section 12. Thereafter, the current position is continuously calculated by the self-contained inertia navigation measurement section 5, and shown in the display section 12, using the current position obtained with the GPS navigation as an initial set position. In this case, when transmission data from one or two earth satellites is received by the GSP receiving section 1, a complex arithmetic section 8 obtains the current position through arithmetic processing, combining the GPS and self-contained navigations. This current position is used as an initial set position for continuing to calculate the current position of the mobile body with the aforesaid section 5 and display the position in the display section 12 through the self-contained navigation.
