Abstract: A piezoelectric resonator unit comprises a first enclosure portion that includes a first principal surface portion and a substantially curtain-shaped portion which cooperate to define a first recessed portion. The first principal surface portion has a first flat principal surface and the substantially curtain-shaped portion surrounds the first principal surface when viewed from a normal direction to the first principal surface. A second enclosure portion has a flat second principal surface and cooperates with the first recessed portion to define an enclosure which houses a piezoelectric resonator. A brazing material joins a distal end of the first enclosure portion to the second enclosure portion to hermetically seal the enclosure. An inner peripheral surface of the substantially curtain-shaped portion includes a stepped portion that is defined by adjacent thicker and a thinner portions of the substantially curtain-shaped portion. A surface of the stepped portion is formed of a single material.

Abstract: A chair type massage machine provided with treatment tools for treating prescribed locations of a human body, and also provided with a touch panel constituting a display device for displaying a treatment menu and other selection items and an operation device for selecting and operating the selection items, and a memory device for storing display information relating to selection items to be displayed on the touch panel; wherein at least a portion of the display information is standard display information relating to a standard mode for displaying a plurality of action selection items on the display means, and simple display information relating to a simple mode with fewer action selection items compared to the standard mode, and the chair type massage machine also has a mode switching processing unit for switching between the standard mode and the simple mode.

Abstract: A method for adjusting the frequency of an electronic component device includes the step of etching an electrode disposed on a surface of the electronic component device by irradiating an ion beam onto the electrode. The ion beam irradiation is performed while moving at least one of the electronic component device and the ion beam in directions along the surface on which the electrode is disposed.

Abstract: A piezoelectric resonator includes a base member in which piezoelectric layers and internal electrodes are laminated. At one side surface of the base member, the internal electrodes are alternately covered with a first insulating film and with a second film, and first and second external electrodes are disposed thereon alternately connecting the internal electrodes to the first and second external electrodes. An additional material is disposed on the side surface of the base member opposite from the side surface on which the external electrodes are formed by applying ink via an ink jet printer or the like. The additional material is disposed at the opposite ends of the base member in the longitudinal direction. A metal film may also be disposed at a central portion of the base member by a thick film forming method.

Abstract: A piezoelectric resonator having a small spurious resonance and a large difference .DELTA.F between the resonant frequency and the antiresonant frequency has a compact size and an external electrode has a structure which prevents damage or breaking of the external electrode. The piezoelectric resonator has a substantially rectangular-parallelepiped base member which includes a plurality of laminated piezoelectric layers. A middle portion of the piezoelectric layers is polarized in opposite directions relative to each other. On main surfaces of the middle part of the piezoelectric layers, first and second groups of inner electrodes and are exposed alternately at both side surfaces of the base member. On both side surfaces of the base member, first and second external electrodes are arranged so as to alternately connect to the first and second groups of inner electrodes.

Abstract: An apparatus and process for forming at least one electrode of an electronic component includes the steps of preparing a work; placing a mask on a principal plane of the work; and applying an electrode material over the mask onto the principal plane of the work to form at least one electrode. The mask preferably comprises, for instance, a first masking portion having a substantially rectangular loop shape and a second masking portion having a substantially rectangular shape, and four pseudo masking portions shaped into substantially rectangular strips and which support the first masking portion. In this case, four through holes are formed in the masking member by the synergistic function of the first masking portion, the second masking portion, and the pseudo masking portions.

Abstract: A viewfinder device has an objective lens element (2) disposed on a viewfinder light path and an eyepiece lens element (3, 28) disposed behind the objective lens element. An image (10) of an object (7) is observable at an eye point (EP). At least one indicia portion (4, 12, 13, 20, 25, 35, 36, 40a, 40b) is disposed in front of the eyepiece lens element, for indicating information related to a taking field. At least one micro lens (5, 5a, 5b, 6a, 6b, 9a, 9b, 14, 17, 22, 30, 32a, 32b) has positive power, is disposed behind the indicia portion, renders an image of the indicia portion observable, and meets0.5.ltoreq.2e.multidot.tan .theta..ltoreq.2.5where e is a distance from the micro lens to the eye point, and .theta. is a half of an angle defined by a convex surface of the micro lens as viewed from the eye point.

Abstract: There is disclosed a submarine cable grapnel which is tied to the two rope of a cable ship and is dragged on the bottom of the sea, one grappling unit and at least one attitude stabilizer is connected while this assembly is connected at one end the two rope of the cable ship and at the other end a chain. In this instance, front and rear coupling portions of the grappling element and the attitude stabilizer are positioned so that the center of gravity of each element under the water stays nearer the seabed than a straight line joining the coupling centers of the coupling portions of the elements when the grapnel lands in the normal attitude on the bottom of the sea.

Abstract: A video signal coding system includes multiple sources to load a digital version of a composite video signal into an associated storage memory. The several memories or memory portions are interrogated employing a common reference wave to obtain the stored digitized video signals in synchronism with one another.In accordance with the principles of the present invention,feedback circuitry is employed in each digital video signal source to sample each video program in a like phase relationship with respect to the signal color burst. Accordingly, the color information is reliably preserved and is in synchronism between video programs upon signal read out from memory.
