摘要:
The present invention provides a method for manufacturing an electronic component of laminated ceramics such as a laminated ceramic capacitor in which, when a ceramic paste is applied on a ceramic green sheet in order to substantially eliminate steps caused by the thickness of a film of inner circuit elements such as an inner electrode, the ceramic paste is prevented from generating a gap between the paste and the film of inner circuit elements, or the thickness of the ceramic paste is prevented from being increased, by allowing the paste to overflow the film of inner circuit elements, even when the application position has been a little shifted, wherein an inclined face is formed at the periphery of an inner electrode that serves as the film of inner circuit elements, the ceramic paste being applied so as to overlap the periphery of the inner electrode, and wherein the used ceramic paste contains about 40% by weight to 85% by weight of solvents in order to facilitate smooth leveling of the applied ceramic paste.

When the step of transferring a ceramic green sheet held on a chuck head having a holding surface with a plurality of vacuum ports distributed thereon onto a depositing table is repeated to obtain a laminated product, undesired deformation or damage is produced on the ceramic green sheet due to negative pressure applied to the chucking port and an obtained monolithic ceramic electronic component becomes defective by aligning of portions having the deformation or the damage in the depositing direction. In order to solve this problem, when transferring of the ceramic green sheet is repeated in the depositing step, the relative positions of the chuck head and the depositing table are shifted so as to bringing the chucking port into the same position during a first transferring step and a subsequent second transferring step.

An acceleration sensor comprises a fixed case member and a cover assembly collectively defining a closed space in which the oscillation plate and the piezoelectric element received therein. The oscillation plate and the piezoelectric element are oscillatably supported by a supporting portion formed on the central bottom portion of the fixed case member. The oscillation plate and the piezoelectric element are integrally oscillatable in two different modes consisting of: a 1/1 oscillation mode where the oscillation plate is irregularly deformed to have the peripheral portion oscillated with a single vector in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a resonance frequency f0; and a 1/2 oscillation mode where the oscillation plate is irregularly deformed to have two different half parts of the peripheral portion oscillated with their respective different vectors opposite to each other in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a noise frequency f01, and the resonance frequency f0 and the noise frequency f01 are out of the range of effective oscillation frequencies. Thus constructed acceleration sensor is of high performance and appropriate for automatic production at a low cost.

The network system is a server-client type network system including a server machine 10 for storing the data of a plurality of pages which are described in a language along the specification of the HTML to be hyperlinked, and a plurality of user terminals 30 for displaying a page of the server machine on a display by using a Web browser. The server machine 10 includes a data transmission unit 80 for spontaneously transmitting the data described in the language along the specification of the HTML to an arbitrary user terminal. Each of the user terminals 30 monitors reception of the spontaneously transmitted data by using the Web browser and displays the received spontaneously transmitted data on the display.

A projection type display system having an optical modulation unit which modulates light from a light source in response to preselected video signal data, a projection lens system for projecting the modulated light onto a display screen, and a focal adjustment device which is configured to alter the focal state of a resulting image which is focused onto the screen. The focal state is adjusted by translating the relative position of one or more lenses in the projection lens system with respect to the screen. The focal adjustment device further incorporates a range finding unit which determines the distance between the projection lens system and the targeted display screen, typically using a beam of invisible light, and an automatic adjustment element which adjusts the focal point of the projection lens system to optimally match the determined distance.

摘要:
A method for manufacturing a laminated ceramic electronic component is provided in which a plurality of ceramic green sheets having printed strip inner electrodes patterns, each including a thick portion at a width-direction center and thin portions at respective width-direction sides of the thick portion, are laminated so that the thin portions overlap and the thick portions do not overlap to form an unfired mother laminated body. This unfired mother laminated body is cut along predetermined cut lines that are vertical to each other to obtain a plurality of unfired ceramic element assemblies. By applying ceramic paste to cover exposed portions of inner electrode patterns exposed to lateral surfaces, side gap areas are formed between a first inner electrode pattern and first and second lateral surfaces of the unfired ceramic element assembly and between a second inner electrode pattern and the first and second lateral surfaces.

A work attracting apparatus and a work attracting method that uses a Bernoulli chuck or the like as a work attraction section and that can ensure the perfect operation of attracting and receiving. The work attraction section (Bernoulli plate 1 and Bernoulli arm 2) attracts a wafer 14 being transported in; a movement section (moving unit 3 and speed variable actuator 10) moves the work attraction section in a direction of transport of the wafer 14; a work detector 4 detects the wafer 14 being transported at a predetermined position and outputs a detection signal; and a controller 5, when receiving the detection signal, controls the movement section to move together with the wafer 14 being transported and makes the work attraction section operate.

An acceleration sensor comprises a fixed case member and a cover assembly collectively defining a closed space in which the oscillation plate and the piezoelectric element received therein. The oscillation plate and the piezoelectric element are oscillatably supported by a supporting portion formed on the central bottom portion of the fixed case member. The oscillation plate and the piezoelectric element are integrally oscillatable in two different modes consisting of: a {fraction (1/1)} oscillation mode where the oscillation plate is irregularly deformed to have the peripheral portion oscillated with a single vector in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a resonance frequency f0; and a ½ oscillation mode where the oscillation plate is irregularly deformed to have two different half parts of the peripheral portion oscillated with their respective different vectors opposite to each other in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a noise frequency f01, and the resonance frequency f0 and the noise frequency f01 are out of the range of effective oscillation frequencies. Thus constructed acceleration sensor is of high performance and appropriate for automatic production at a low cost.
