Title: Piezoelectric resonator
Inventor: TANAKA YASUHIRO
IPC: H03H9/56
Filed: 1990-05-21
Abstract: PURPOSE:To prevent the characteristic of a piezoelectric resonator from being degraded by forming more than two piezoelectric resonance parts on the same piezoelectric substrate and capacitor parts respectively between these piezoelectric resonance parts, and mutually inverting the polarizing directions of the adjacent piezoelectric resonance parts. CONSTITUTION:This piezoelectric resonator is composed of oscillating electrodes 14 and 14 formed on one face of a piezoelectric substrate 12, capacitor electrode 16, drawing electrodes 18 and 18 and common electrode 20 formed on the other face. The piezoelectric substrate 12 is polarized by fitting the electrodes on the both sides of a piezoelectric board, which is board-shaped by a piezoelectric body, and impressing a high voltage between the electrodes, and the polarizing direction is inverted with the almost central part of the piezoelectric substrate 12 as the boundary. Thus, the piezoelectric resonator can be obtained with a satisfactory characteristic by respectively canceling each other either an electric field to be generated by the piezoelectric resonance parts formed at spots in various polarizing directions or oscillation to be generated by the electric field applied to the capacitor parts.

Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To manufacture a built-up board which is possible of high density and possesses a blind via hole high in relative positional accuracy. SOLUTION: A copper foil 5 where thermosetting resin 4 is applied is stacked and bonded to the core material 2 having an inner layer patter 1 of a multilayer substrate, and the copper foil 5 in the section where a hole 8 is positioned is removed by the etching by photolithography to make a small-diameter hole 8, and a laser beam is applied to the parts including the entire hole, and only the resin part is extinguished, making use of the divergence of absorption factor to the laser between the copper foil 5 and the resin 4', so as to make a hole 8 for a blind via hole which reaches the core material 2.  Since it gets in the process of forming the hole after stacking and bonding the copper foil 5 where the resin 4' is applied to the core material 2, the layer of the resin 4' absorbs the irregularity of the core material, so the smoothness increases, and it becomes easy to form the final pattern, and since the holes for formation of blind via holes are formed en block by photolithography, the accuracy in the relative position between the holes becomes high.

Title: Circuit device for analog comparator
Inventor: ROOBERUTO REHINAA
IPC: H03H19/00
Filed: 1980-09-25
Abstract: An analog-to-digital converter for converting analog signals received in parallel on a plurality of incoming lines into digital signals comprises a selector unit having a plurality of signal inputs. Each input is connected to an incoming line via a filter capacitor. A grounded network connected to an output of the selector unit has a storage capacitor and a switch arranged in parallel for short-circuiting the capacitor temporarily. The network simulates a common resistor for establishing a filter section together with the presently through-connected filter capacitor. One input of a comparator is connected to the selector output. The second input is supplied by an analog reference voltage source which may comprise a digital-to-analog converter for supplying an analog reference voltage adjustable under control of the current condition of the comparator output signal. The reference voltage thus is iteratively approximated to the current analog value of the stored sampling probe.
