Title: Ultrasonic probe
Inventor: FUJIWARA MITSUHIRO
IPC: H04R17/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic probe which has superior transmission and reception characteristics and superior operability by increasing the thickness precision of a sound matching layer by applying a piezoelectric body to a sound matched layer. SOLUTION: This ultrasonic probe is constituted by providing the sound matched layer 2 in double structure on a piezoelectric element 1 as PTZ having electrodes 3a and 3b on both its main surfaces. The sound matched layer 2, for example, has a crystal plane as its 1st layer 2a and a coating of epoxy resin as its 2nd layer 2b. The crystal plate is cut, in what is called an X cut style, so that the plate surface is at right angles to the X-axis against crystal axes (XYZ). The acoustic impedance of this crystal plate therefore becomes about 15×106 kg/m2/s similarly to that of glass. Then this plate has natural vibration frequency of mechanical resonance in response to an alternating voltage applied between both the main surfaces as well as the piezoelectric element 1.  Consequently, the thickness accuracy of the sound matching layer 2 is improved and an ultrasonic probe having superior transmission and reception characteristics and good operability is obtained.

Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent such mistakes photography that any item other than an intended object is reflected in a picture plane from being taken by performing release when cancel waiting time has elapsed after range-finding. SOLUTION: When a camera is set in a remote control reception mode, a CPU 1 turns on the power source of a remote control IC 3, and when a specified signal is inputted from an external remote control operating device, a substance distance is measured by an AF(autofousing:automatic range-fiding) IC, and the result of the range-finding is displayed on a display means. After waiting for two seconds, releasing operation such as focusing, opening/closing a shutter and film feeding is performed through IF(interface) IC 6. Waiting for two seconds is to give the degree of freedom in pause so as to prevent the hand of a person holding the external remote control operating device from being reflected in the picture. For example, an LED is used as the display means for displaying the result of the range-finding, and a strobe light emitting device 4 is used instead of the LED.
