Title: Laminated piezoelectric element
Inventor: KAWAMURA YUKINORI
IPC: H01L41/083
Filed: 1988-03-07
Abstract: PURPOSE:To moderate the concentration of shearing stress produced at a boundary between a protective layer and a piezoelectric material layer for improving the reliability of a life by providing adjoining to the protective layer a stress moderating layer comprising a piezoelectric material having a relatively small transverse voltage-strain constant. CONSTITUTION:A laminate type piezoelectric element includes a protective layer 23 comprising a piezoelectric material provided through an electrode layer 21A at both ends of a laminate which is formed by alternately superimposing piezoelectric material layers 20, 20A, and the electrode layer 21A and an electrode layer 21B. External leads 22A, 22B are electrically connected to the electrode layers 21A, 21B at every other electrode layer. The piezoelectric material layer 20A adjacent to the protective layer 23 is constructed as a stress moderating layer which has a smaller transverse voltage-strain constant than that of the piezoelectric material layer 20 comprising the same material as that of the piezoelectric material layer 20. With an electric field applied, elongation strain S1 is produced in a direction of the superimposition by a longitudinal piezoelectric effect, and contraction strain S2 is produced by a transverse effect in a direction perpendicular to the superimposition direction. Since the protective layer 23 is not deformed, the contraction of the piezoelectric material layer 20A is restricted to about 1/2. Thus, concentration of the shear stress is moderated.

Title: Control method for electromagnetic fuel injection device
Inventor: WATANABE YUKIHIRO
IPC: F02D41/20
Filed: 1985-03-15
Abstract: PURPOSE:To spread a dynamic range of a fuel metering quantity, by turning on only an auxiliary coil, connected in series, when pulse electrification to a main coil is turned off and turning off the auxiliary coil when the main coil is turned on. CONSTITUTION:When a pulse electrification output to a main coil 3 from an injector valve opening time arithmetic part 31 is turned off, a transistor TR2 is conducted by an output of an inverter INT1, turning on only an auxiliary coil 12. Next, if the pulse electrification output is turned on, a transistor TR1 is conducted to turn on the main coil 3, while a device, rapidly decreasing an electric current flowing in the auxiliary coil 12 by an inverted output L of the inverter INT1, allows a peak current by the counter electromotive force of the coil 12 to flow overlapping with the current in the main coil 3, and the plunger of an injector is almost synchronously attracted with a rise-up of the pulse electrification output. In this way, the device, enhancing a response characteristic of a fine flow, enables a dynamic range of a fuel metering quantity to be effectively spread by the simplified method.

Title: Working machine control device for construction machine
Inventor: IMAI HIROSHI
IPC: E02F3/43
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To perform fine operation work without imposing a burden on an operator by detecting the height position of a working machine, and limiting the maximum rotating speed of a second front member to the specified value or less in the case of the detected height position being a specified height position or lower. SOLUTION: The height position of a working machine is detected by detecting the rotating angle of a first boom 5. In case of the detected height position of the working machine being a specified height position or lower, the maximum rotating speed of a second front member 11 is limited to the specified value or less. The working speed of a front member 7 to be a second boom is therefore limited to low speed of the specified value or less without fine adjustment of a second boom operating pedal 47 by a foot. An operator is therefore liberated from fine operation work of the second boom, while the working speed of the second boom is not limited to low speed when the working machine is in a high position, so that work efficiency can be heightened.

Title: Mos analog amplifier and cmos stationary circuit circuit
Inventor: RI GIYOUKIN
IPC: H03K19/0944
Filed: 1989-03-07
Abstract: PURPOSE: To obtain the sophisticated performance circuit not relying on the bipolar technology by configuring the amplifier with a stead-state current source, a reference MOS transistor(TR) and one or a plurality of input MOS TRs. CONSTITUTION: When inputs V1 -VN including signals with higher voltage than a reference voltage denoting logic 1 are given to gates of a plurality of input NMOS TRs 21-2N, the TRs receiving a logic 1 signal are conductive and all currents from a steady-state current source 3 flow to a TR 5. When all the inputs V1 -VN are lower than the reference voltage, all currents flow to a TR 4. Thus, a standard NOR gate is realized at an output terminal of drains of a plurality of the input NMOS TRs and a standard OR gate is realized at an output terminal of a drain of a reference NMOS TR 1. Thus, the NMOS analog NOR amplifier is formed not relying on the complicated bipolar technology requiring much cost.
