Title: Structure for dual beam piezoelectric resonator
Inventor: KURIHARA MASAO
IPC: G01D5/48
Filed: 1987-05-15
Abstract: PURPOSE:To reduce a leak of vibration energy by providing notchs of necessary depth in boundary parts between a beam as a vibration part and support parts at both ends of the beam as stress application parts for the beam. CONSTITUTION:Both ends of the columnar beam 1 as the vibration part are coupled by the supporting parts 3 of large area across boundary parts 2 which are a little bit wider than the beam. The columnar beams 1 are arrayed in parallel at a necessary interval and both ends of both beams 1 are coupled integrally; and the boundary parts 2 between the supporting parts 3 and beam part are made narrower than the supporting parts 3 and wider than the beam part 1. Then the notchs 4 of necessary depth are formed in the boundary parts 2. Consequently, the leak of vibration energy is reduced greatly to increase the sharpness of resonance, so the load on the side of an oscillation circuit is reduced and variation in frequency due to disturbance is suppressed.

The plural detecting regions A to D are formed through the optical system 1 on the same object surface in the same disposition as the disposition of the detectors 2A to 2D on the focal plane. The respective detectors 2A to 2D generate outputs as a change in the temp. difference from the background by the movement of the human body in the regions A to D. An amplifier 3 amplifies the outputs from the detectors 2A to 2D. A filter 41 removes the unnecessary low-frequency components and high-frequency components from the outputs of the detectors 2A to 2D. A comparing section 42 compares whether the peak value of the signal outputted from the filter 4 exceeds a preset reference value or not and outputs the same to an output section 5.

Abstract: PURPOSE:To always expose correctly by setting a main light emitting quantity basing on an output by a main light emission detected at a photodetecting part, also detecting turn to the main body of a head part after a pre-light emission, and executing a turn indication of the head part by a warning signal.

In this case, after the pre-light emission, if a photographer turns a head part 3 by mistake and executes the second stroke operation as it is, a brush and a comb-tooth is reduced to a non-contact state temporarily, and switches 140a, 140b go to off-state, therefore, an anode of a latching circuit is reduced to a low level, latching circuits 85-87 cancel a latched state by the pre-light emission, and the contents of all the latching circuits attain forcibly a low level. Accordingly, an LED 104 is lighted and informs that the head part has turned, and a suitable warning display can be executed.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent degradation in piezoelectric characteristics in a piezoelectric element, to enhance an adhesive strength of an electrode, and to reduce the processes for bonding for improved yield. SOLUTION: A thin-film electrode for a piezoelectric element used for a sounding body is formed by a sputtering method. In a vacuum atmosphere oven 44, a piezoelectric ceramics 41 is covered with a mask 42 for sputtering. A sputtering target 43 is used, which comprises a copper content with a silver as main component at 1.0-10.0% in weight ratio. The sputter target 43 is made to collide with incident ions 45, so that a thin-film electrode of a constant thickness which contains a copper component by a specified amount is formed on the surface of the piezoelectric ceramics 41. A vibration plate containing at least one of nickel and iron as a component is bonded to a piezoelectric element, using an ultraviolet-curing type anaerobic bond.  Since an electrode itself provided with a curing acceleration effect is used, no curing acceleration agent containing copper ion is required for coating, thus man-hours are reduced and yield is improved.

Abstract: PURPOSE:To detect air fuel ratio with high precision without providing any element for temperature compensation by providing a gas detecting element and a metallic heating resistor on the same substrate and constituting a sensor, and making the output of an electric generator regulator into a reference voltage through a reference voltage generating circuit. CONSTITUTION:The gas detecting element and metallic heating resistor are mounted on a ceramic plate to constitute the gas sensor, which detects resistance due to variation in the thickness of gas component and is heated to activate the detecting element.

The divided voltage is applied to the gas detecting element HT and inputted to a comparator C. Further, the voltage is inputted from the generator regulator to series resistances R4 and R5 and inputted from their intermediate connection point to the other terminal of the comparator C as a reference voltage. Therefore, the reference voltage is applied depending upon the voltage of the regulator as the source voltage for a heater, so the circuit constitution is simplified.

Abstract: PURPOSE:To prepare a zirconia sintered body having high strength and thermal stability and to prevent chipping during processing and generation of crack in the sintered body by specifying a content of Y2O3 and CeO2, crystal particle size, crystal structure and particle size of cubic crystal of zirconia. CONSTITUTION:The title zirconia sintered body consists primarily of zirconia of tetragonal crystals consisting of 2-3.5mol.% Y2O3, 0.1-<0.5mol.% CeO2 and having <=1mu mean crystal particle size, wherein <=10vol.% monoclinic crystals and 0 or <=5vol.% cubic crystal having <=1mu particle size are contained. If the content of Y2O3 is out of the above-described range, high strength is not attained. If the content of CeO2 is below the above described lower limit, the thermal stability is not improved. If it is > the upper limit, exhibition of the strength attains insufficiently. If the mean crystal particle size of the sintered body exceeds 1mu, the stability of the tetragonal crystal decreases. When cubic crystals are contained and the crystal particle size exceeds 1mu, the strength decreases remarkably and the processability deteriorates.
