Title: Magnetic brush developing device
Inventor: NAKAGAWA HIRONORI
IPC: G03G15/05
Filed: 1981-04-15
Abstract: PURPOSE:To obtain a high-contrast picture, by applying intermittently the positive voltage applied to the development electrode of an electronic recorder to the high and low levels of voltage alternately. CONSTITUTION:Countless toners (. mark) and carriers (O mark) are mixed in a developing device 4 and stirred by a stirrer 1. Thus the toner and the carrier are charged positive and negative respectively to be circulated toward an arrow mark by rotary drums 6 and 6'. These drums switch the bias voltage to a low level from a high level by a pulse oscillator 10 plus voltage dividers 8 and 9 synchronously with an inductive drum 2 via a development electrode. The development electrodes 6 and 6' are biased to a low level of positive voltage by a moment when a latent image formed with the negative high voltage pulse reaches the device 4. A switch 5 is switched when the latent image reaches the device 4, and thus the electrode 6 and 6' are biased to the positive high voltage. As a result, the toner is strongly attracted to the latent image part to produce a high- contrast picture.

Title: Electro-mechanical transducer and ink jet recorder using the same
Inventor: YASUTOMI HIDEO
IPC: H01L41/09
Filed: 1995-03-15
Abstract: PURPOSE: To increase the displacement amount and the generated force by applying a voltage to a piezoelectric element in which at least its part is not fixed to a board to form an electric field in parallel with the its polarizing direction, and so displacing that the part of the element not fixed to the board is deflected. CONSTITUTION: A voltage is applied between electrodes 4 and 5 by voltage applying means 6, and an electric field is applied in the direction of an arrow E parallel to the polarizing direction P. Thus, since a piezoelectric element 3 is fixed to a board 2 only in a fixed area S but not fixed to the board 2 in a non-fixed area (t), it is so displaced that the area (t) not fixed to the board 2 is deflected upward. The displacement amount at this time is increased separately from the area S toward the free end. When the applied voltage of the means 6 is removed to eliminate the field, the deflected displacement of the area (t) not fixed to the board 2 is eliminated, and it is returned to the initial state.

Title: Exhaust temperature controller for engine
Inventor: AKAGI YUJI
IPC: F01N99/00
Filed: 1989-03-07
Abstract: PURPOSE:To lower an exhaust temperature without entailing any drop in engine performance by making a current, generated by exhaust gas traversing a magnetic field in an exhaust passage, flow into an electric circuit with an electrode an a current consumer. CONSTITUTION:When temperature comes to its high exhaust range at high speed and load, a switch 31 is closed by a control unit 1 and electromagnets 20, 21 are energized with current. With this energization, a magnetic field is generated in a branch exhaust passage 12 in a cylinder member 17, thus electric power is generated, and when this generating voltage becomes more than the conducting voltage of a diode 36, a battery 32 is charged via a voltage regulating circuit 33. Accordingly, a part of heat energy in exhaust gas is converted into electric energy, where by an exhaust temperature is lowered as much as a portion for that. Consequently, the exhaust gas cooled by power generation at a generating set 15 is fed to an exhaust system, thus a temperature rise in this exhaust system is checked.

Abstract: PURPOSE:To improve an output voltage by placing a mass body in the hollow part of a hollow cylindrical body, providing a flexible partition wall so as to come into contact with both end faces of a projecting part of this mass body, and interposing and installing a differential pressure sensor in a fluid path for conducting to one end part and the other end part of the hollow cylindrical body. CONSTITUTION:In the inside of a housing, a differential pressure sensor 5 is fixed to the side of one end 2d of a hollow cylindrical body 2, and a holding body 9 to which a flexible partition film having projecting parts 3L, 3R on both ends is fixed is provided on the other end part 2c side with a fluid path R1 between. For instance, it is supposed that some acceleration has worked on this acceleration detector. As a result, the whole detector moves in some direction, but as for a mass body 3 in the inside, it executes a motion so as to stay at the present position. Therefore, the projecting parts 3L, 3R of the mass body 3 push the flexible partition film 8. Its force F pushes a non-compressive fluid 6 and an output voltage can be obtained from the differential sensor. The pressure in this case is obtained by dividing the force F by an area of the flexible partition film 8, and the smaller this area is, the more the stress increases. Therefore, even by an acceleration or a mass body of a very small quantity, a sufficient output is obtained.
