Title: Protective case for electronic equipment
Inventor: HINO MARIKO
IPC: A63F13/98
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To improve both the overall sealability and operability of a protective case for electronic equipment by blocking the through-holes corresponding to the pressing sections of an electronic apparatus housed in a void section with tightly closing members, after sealing the space between the butting sections themselves of an upper case and a lower case which are integrally formed of an elastic material. SOLUTION: When a portable electronic equipment 100 is housed in a protective case 160 with the displaying section 130 of the apparatus 100 on an upper case 161 side, push-buttons 165 correspondingly come into contact with the pressing surfaces of operators 121 and 122. Therefore, when the push-buttons 165 are depressed while the equipment 100 is housed in the case 160, depress switches can be depressed through the operators 121 and 122 and depressing sections. Since the external wall section of the case 160 at the position corresponding to the displaying section 130 of the apparatus 100 housed in the void section of the case 160 is swelled out in a concave section, the section works as a concave lens and magnifies the displaying section 130.

Abstract: PURPOSE:To use plural light beams as a light projector or a light receiver so as to detect a matter by mounting a diffraction grating, which has a function to divide up a light projecting beam and a light receiving beam, in front of a light projecting/receiving device. CONSTITUTION:In a light projector 1 of a transmission type photoelectric sensor, a diffraction grating, which has the equal width to the front face and the equal height to a lens face of a light projecting part, is installed in the front face and is fixed on the front face of a box body of the light projector 1. For example, the light projector 1 is arranged on the side of a belt conveyor 4 while light receiving devices 5A, 5B, 5C are arranged so that they face three directional projecting beams of the projector 1 respectively. The matter is determined on the basis of the logical sum of matter detection outputs from these individual devices 5A-5C. In this way, it is considered that either of the light beams is intercepted even when a part of the matter to be detected is bent, so that the matter can be detected without any error.

Title: Ultrasonic probe
Inventor: ISHIKAWA YASUO
IPC: A61B8/00
Filed: 1985-03-15
Abstract: PURPOSE:To eliminate an unnecessary vibration arising in a read terminal part and to obtain a ultrasonic wave picture having an excellent S/N ratio by removing an electrode surface facing the read terminal connecting part of a ultrasonic wave vibrator. CONSTITUTION:Electrode parts facing the read terminals 2 and 3 of the electrodes 1a and 1b of the ultrasonic wave vibrator are removed by installing opening holes 7 and 8. Thus a piezoelectric element 1 does not have a piezoelectric characteristic at polarization, that is, when a high electric field is previously impressed in order to obtain a usefull piezoelectric effect, because opposite electrode parts are removed out of the parts of the read terminals 2 and 3. As a result an elastic wave caused by the vibration of the piezoelectric element 1 will not be propagated to the read terminals 2 and 3, a soldered part or lead wire, and the S//N can be improved. Even if a signal at a low level, whose signal frequency band is wide, is handled, the S//N can be improved.
