Inventor: ODA MASAHIRO
IPC: B41J2/175
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer having a plurality of ink ejection nozzles whereby clogging hardly occurs. SOLUTION: In a print head 2, a common 7a on a substrate 8-1, and a cutting electrode 7b and accelerating electrodes 7c on a substrate 8-2 are opposed to each other and an ink passage 9 of which inner wall is covered with water- repellent films 14-1, 14-2 is formed. Ink 11 in an ink tank 3 is introduced from an ink stand-by section 12 having a water-repellency to the cutting electrode 7b to be cut. The ink becomes an ink droplet to be accelerated to a direction X in the ink passage 9 having the water-repellency by virtue of a Maxwell's distortion by an electric field which is sequentially generated toward a side of an ejection nozzle 16 by the plurality of accelerating electrodes 7c. The ink droplet is ejected from the ejection nozzle 16 to a surface of a recording paper to form one dot thereon.  In the case where plural sets of the common electrode 7a, cutting electrode 7b and accelerating electrode 7c are juxtaposed in the direction Y (paper width direction), it is possible to constitute a print head capable of printing a plurality of dots at the same time.

IPC: H01L41/08
Filed: 1984-02-28
Abstract: PURPOSE:To obtain a vibration element having a high mechanical strength and in which the strain amount can be increased by reducing the thickness of the vibration element and setting the backward voltage of a piezoelectric material within an allowable range. CONSTITUTION:A piezoelectric vibrator is used for the pressing part of liquid, gas or powder pump. The vibration element 1 of the piezoelectric vibrator is operated by the transistors Tr1 and Tr2. A resistor R3 is inserted between the bases of the transistors Tr1 and Tr2. The backward voltage applied onto the vibration element 1 is controlled within an allowable range by reducing the base voltage of the transistor Tr2 by the resistor R3. The forward voltage is applied by the transistor Tr1 having a high base voltage. Thus, the applied voltage of the vibration element 1 is allowed to have the wave form which is asymmetrical in the vertical direction, in other words, the applied voltage is large in the forward direction and small in the backward direction. Therefore, the discharge amount of a pump can be increased by increasing the strain amount of the vibration element 1.

Abstract: PURPOSE:To aim at prevent a vehicle from slipping, by providing such a control device for a vehicle automatic transmission that the occurrence of a slip is determined in accordance with the rotational speeds of front and rear wheels, and the gear shift position is set at the neutral position of the transmission. CONSTITUTION:A slip determining means 13 determines the presence of a slip in accordance with signals from front and rear wheel speed detecting means 11L, 11R, 12L, 12R. When the occurrence of a slip is detected, the output of the means 13 is delivered to a control device 14 which therefore sets the gear shift position of an automatic trnsmission 4 at the neutral position. Therefore, the gear change is made, simultaneously with occurrence of a slip, to make zero torque transmitted to the tires so that the duration of the slip is limited to a short time. This arrangement may be simply incorporated in a conventional vehicle with automatic transmission.

IPC: H01L39/22
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a device structure wherein the magnetic flux generated by a supplied bias current does not exert adverse effect on other elements integrated on the same board, in a superconducting quantum interference device(SQUID) of high sensivity and low noise which detects fine magnetic field, current, voltage, electromagnetic wave, etc. SOLUTION: A bias wiring layer 4 for applying a bias current to a DC-SQUID is formed and arranged on the upper layer or the lower layer of a superconducting ring of the DC-SQUID. Wiring is so formed that the bias wiring layer 4 passes a symmetrical axis which divides the superconducting ring into two halves. By arranging the bias wiring layer 4, generation of magnetic flux which is caused by the bias current can be restrained. Since interference due to the bias current is not generated on the DC-SQUID itself its peripheral part, adverse influence is not exerted on elements integrated on the same board. Especially in an SQUID array, phases of magnetic flux-voltage characteristics of the respective constituent DC-SQUID's are easily conformed, and it largely contributes to enlargement of a modulation voltage.
