Title: Leaky saw resonator
Inventor: MORITA TAKAO
IPC: H03H9/145
Filed: 1991-10-24
Abstract: PURPOSE:To obtain a leaky SAW resonator for voltage control oscillator which does not generate ripple in a frequency variable area by arranging an inter- digital transducer electrode, inclining it by only a specific angle for the X-axis of a 64-degree cut LiNbO3 substrate. CONSTITUTION:An inter-digital transducer electrode 2 for exciting a leaky SAW is arranged on a 64-degree Y cut LiNbO3 substrate 1 whose coupling factor is large by inclining the electrode 2 by 3 deg. to 8 deg. for a X-axis which is a leaky SAW propagation direction. By this, a spurious on a lower band side than a resonance point almost extinguishes. This reason is considered that a resonator Q lowers to some degrees by slightly being shifted by the propagation direction of the leaky SAW and the propagation direction of the energy. But as the lowering of the Q is no more than about 10%, the value is endurable one practically when this resonator is used for a voltage control oscillator. In future, the resonator is applicable to ones which are used in wide- band multi-channel communication equipments of which the necessity is increased.

The total number M of a group of the elements to be evaluated and the discriminated groups is determined. The distribution degree of the element to be measured is evaluated by the value obtd. after the value obtd. by dividing the standard deviation by the average value is multiplied by the value (correction factor of the fluctuation rate) obtd. by dividing the number M by the number N.

Filed: 1991-10-25
Abstract: PURPOSE:To prevent the flash of a molded article from developing by improving the sealing properties of the mating surfaces of a foaming resin mold. CONSTITUTION:Lip-like sealing members 9 and 10, which are made of elastic body, are provided around the peripheral edge part on the cavity B side of the mating surfaces of an upper mold 7 and of a lower mold 8. Firstly, a foaming resin such as polyurethane or the like is poured in a cavity B under the condition that the upper mold 7 and the lower mold 8 are opened. Next, the upper mold 7 and the lower mold 8 are clamped together at the predetermined interval D between them so as to seal the mating surfaces 9 and 10 into close contact with each other. At this time, as being elastic body, the sealing members 9 and 10 deflect so as to elastically come into close contact with each other and the unevenness and dimensional tolerance of the close contacting parts are absorbed. As the foaming in the cavity B proceeds, the sealing members 9 and 10 are further strongly pushed against each other so as to come into close contact with each other by the foaming pressure acting on the relative rear face sides of the close contacting parts of the members, resulting in surely sealing the mating surfaces.
