A method for producing a stacked piezoelectric element alternately stacks a plurality of layers of an electrode material and piezoelectric layers having an electric mechanical energy converting function and provided with penetrating electrodes, obtained by forming through holes in each piezoelectric layer and filling the through holes with the electrode material, to be connected at a contact portion with a layer of the electrode material and sinters the stacked layers. The method includes the step of forming, on a layer of the electrode material, a second layer of electrode material by screen printing at a peripheral area of the contact portion between the layer of the electrode material and the penetrating electrodes.

A guidance system using a telephone number and other information on a subscriber of that telephone number so as to be input and checked, whereby, retrieval and guidance by inputting the telephone number is properly performed. The system has a memory for storing specific information for specifying at least a telephone number and a subscriber and information on a point of the subscriber, an input device means for inputting the specific information for specifying the telephone number and subscriber, a retrieval mechanism for retrieving information on the point of the subscriber on the basis of the telephone number input by input means or specific information for specifying the subscriber, an output controller for controlling an output of information on the point of the subscriber retrieved by retrieval means on the basis of the inputs of the telephone number and the specific information for specifying the subscriber, wherein information is retrieved for a point of the subscriber of the hit telephone number by inputting a telephone number and according to classification of the subscriber whether the subscriber is a private subscriber, a facility, or an entrepreneur of firm, shop or the like. The invention further controls an output of personal information on a condition that a name of the subscriber is input when the subscriber is a private subscriber.

A stacked piezoelectric element includes a plurality of piezoelectric layers and electrode layers stacked alternately in which the electrode layers are electrically connected by a penetrating electrode formed in a conductive hole formed in a direction of the thickness of the piezoelectric layers. The penetrating electrode formed in a piezoelectric layer of a first layer is positioned to overlap with the penetrating electrode formed in a piezoelectric layer of a first layer in the direction of thickness.

A detailed map is displayed on a display screen by using detailed map information. When a building BL on the detailed map is indicated, a user name list of the building is calculated from building information to display the user name list on a part of the display screen, and a detailed map MP displayed on another part of the display screen is inclined by a birds-eye process to be displayed. The indicated building BL is displayed three-dimensionally with a height corresponding to the number of its floors. When a user is specified from the user name list, the floor number of a floor on which the user is located is calculated from the building information. The floor is displayed by an L-shaped mark FL in the three-dimensionally displayed building such that the number of floors can be identified, and/or the floor number is displayed by the characters FLC.

In a piezoelectric transformer device (,), a plurality of inner electrodes are stacked on each other on the left side. These inner electrodes are alternately connected to each other through interlevel connection conductors to constitute two inner electrode groups. A secondary output electrode in the form of a mesh is formed near the end portion of the device (,) on the right side. Only primary input electrodes (,) connected to the two inner electrode groups, a secondary output electrode (,), and the lead electrode of the secondary output electrode in the form of a mesh are exposed on the same surface of the device.
