Patent JP-H0414456-A (JP)
Title: Ink jet head
Inventor: FURUTA TATSUO
IPC: B41J2/055
Filed: 1990-05-08
Abstract: PURPOSE:To stabilize ink discharge characteristic by a method wherein a structure is made up which gives electric actuating signals to only the vibratory part related to the action of a piezoelectric transducer or mainly thereto so as to eliminate the vibrations excited by a nozzle forming member and stabilize a gap between the nozzle forming member and the piezoelectric transducer. CONSTITUTION:An ink is filled between a piezoelectric transducer 1 and a nozzle forming member 8. The ink is fed from the side of the piezoelectric transducer 1 opposite to the nozzle forming member. The piezoelectric transducer 1 acts in response to external electric actuating signals to increase the pressure of the ink near a nozzle opening part 9 and thereby discharge ink drops 3 therefrom, whereby an ink impression is made on a recording medium such as paper adjoining to the nozzle forming member 8. At this time, a fixed part 13A of the piezoelectric ceramics devoid of a thin membrane electrode 14 is freed from the application of the electric actuating signal thereto and, consequently, there is no occurrence of the vibration. Therefore, the nozzle forming member 8 is not subject to the effect of the vibrations excited by the piezoelectric transducer 1, thereby a stable ink discharge characteristic is obtained.

Filed: 1981-07-30
Abstract: PURPOSE:To remove harmful materials such as oils, surfactants, metallic ions and the like in polluted waste water efficiently by treating the polluted waste water by using a screen consisting of roll brushes manufactured of fibers having high oil adsorptivity. CONSTITUTION:A screen is driven together with a gas bubble cylinder 15 by a motor 14 via a worm and a wheel 13 at respective rotating speeds, and a pump 17 is rotated by a motor directly coupled thereto. The polluted raw water supplied through a sewage supply port 3 diffuses on the screen, by which the water is filtered. The oil liquid and fine granular materials failing to be adsorbed join with the stagnating water in a water tank 11 and the materials floating thereon are adsorbed or scooped by the screen and are dislodged together with filter cake by a brush 2. The fine foam groups ascend on parallel inclined plates 12 as foaming pumps by carring the stagnating water and stick on the circulating and suspending fine particles, whereby they are joined, oxidized and flocculated acceleratedly.

IPC: B41J2/05
Filed: 1994-05-31
Abstract: PURPOSE:To lower gas permeability and to prevent the penetration of an air bubble into an ink supply system by forming the ink supply system and ink tank in an ink jet recording head from polyolefin composed of an ethylene/ tetracyclododecene copolymer. CONSTITUTION:An ink jet recording head consists of an ink jet unit IJU, an ink jet head IJH and an ink tank 1000 and an electrothermal converter is allowed to generate heat corresponding to an electric signal to generate film boiling in ink to perform recording.

Title: Apparatus for detachably coupling double gear
Inventor: SCHILD HELMUT
IPC: B41F13/008
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To allow a member for clamping and a body journal to be scarcely relatively rotated by providing a coupling member spring-elastically operating axially without play in a rotating direction between a clamping ring and a member tightly coupled to a sheet guide cylinder. SOLUTION: In a driving unit of the double gear, a tie rod 9 penetrating a main gear 4, gear flange 3 and clamping ring 7 is spring-elastically supported to the ring 7. The rod 9 is loaded by a lap leaf spring 10. The rod 9 is previously regulated to clamp a gear ring 5 at the gear 4. The rod 9 is released from a driving force of a circumferential direction by coupling to a coupling plate 16 without play. Since the plate 16 is relatively thin, it allows axial movement of the ring 7 by an elastic deformation. At the time of eliminating clamping of a separating coupler 11, relative positions among the ring 7, flange 3 and a body journal 1 are continuously the same.

IPC: F16C32/04
Filed: 1992-05-12
Abstract: PURPOSE:To prevent waste of power consumption by estimating a varying state of bearing load to adjust power supply to an eletromagnet. CONSTITUTION:A pressure varying state is monitored based on pressure signals outputted by pressure sensors 4, 5, and based on the pressure varying state a time-based varying period of bearing load and the maximum value of the bearing load are estimated. A computing element 6 actuates a first and a second transistors 12, 13 of an amplifier 7 in order to cope with the estimated bearing load variation. Accordingly, a power source voltage is determined in accordance with a variation value of the bearing load. Control quantity is varied in compliance with the variation of the bearing load. Consequently, in the case of small bearing load, power consumption (supply voltage V X current I) can be suppressed at a small value.

Title: Temperature detection sensor
Inventor: USUI KAZUO
IPC: G01K7/22
Filed: 1994-05-31
Abstract: PURPOSE:To prevent the terminal from being broken by thermal stress and prevent the engaging part, etc., from being mechanically broken, by controlling the content of glass fibers in a resin, making a linear expansion coefficient of a resin case storing a temperature-sensing element and the terminal close to that of the terminal and setting a resin case storing the engaging part at a required strength. CONSTITUTION:The content of glass fibers in a resin case 1 wherein a temperature-sensing element 3 and a signal transmission terminal 4 are integrally molded is increased, so that a linear expansion coefficient of the resin case 1 is made to approximate to that of the terminal 4. Even if the temperature sensor is used in a wide temperature range from a low temperatures to a high temperatures, a stress caused by the difference between expansion and shrinkage is sufficiently small and accordingly, there is no fear that the terminal 4 is broken and electrically fails or the case 1 is broken. Moreover, the content of glass fibers in a resin case 2 is reduced to increase a flexibility. Therefore, such a part as a thin part is prevented from being broken by a mechanical stress.

Abstract: PROBLEM TO BE SOLVED: To change a connection to a server who can shorten communication time much more during communication. SOLUTION: A radio portable terminal (client machine) transmits/receives data with information server machines (1-N) through a radio communication network, a public network and cable communication networks (1-N). When it is judged that time required for the completion of transmission becomes shorter in the case when the connection of a line is changed with information server machines i ((i)=2 to N) during a data communication processing between the client machine and the information server machine 1 at first and data is transmitted from the beginning, the line with the server machine 1 is cut and the connection of the line is changed with the information server machine (i). Then, data is transmitted/received again from the beginning.  A management server machine retrieves the information server machine (i) which exists in an area which is nearer to the information server machine from management data which it itself has and whose throughput is good at timing when throughput information is informed from the information server machine 1 and informs the information server machine 1 of a notice destination of the line number and throughput information.
