IPC: G06F9/44
Filed: 1987-04-08
Abstract: PURPOSE:To narrow down the key data in a retrieving job by giving the hierarchical relation to a complementary information table to secure the hierarchical relation among fields and selecting the lower rank fields having the hierarchical relation with designation of the key data on the higher rank fields only in a retrieving state. CONSTITUTION:The hierarchical relation is given to a complementary information table and also the hierarchical relation is secured among fields. When a retrieving job is carried out, a 1st field element name A1 is designated so that both second field element names A11 and A12 belonging to the element name A1 are known. Then the name A11 is designated so that the 3rd field element names A111-A113 belonging to the name A11 are know. Thus the 2nd field element names can be decided just with designation of the 1st field element name and then the 3rd field element names can be decided just with designation of the 2nd field element name. These actions are repeated so that the retrieving key data can be narrowed down.

Abstract: PURPOSE:To manufacture uniform and reproducible diffractive gratings without using a photolithography by repeating the growths of more than two kinds of crystals one after another on a substrate on which in advance stepped parts are formed differentially. CONSTITUTION:Stepped parts are formed differentially so that the surface of a GaAs substrate 11 makes an angle alpha to a horizontal plane and then, first of all, an AlAs buffer layer 12 is permitted to grow and further, Ga1-xAlxAs 13, i.e., the 1st crystal is permitted to grow. In such a case, the 1st crystal 13 is permitted to grow so that it embeds the stepped parts on respective horizontal planes and then the 2nd crystal, i.e., GaAs 14 is permitted to grow. The 2nd crystal 14 grows at the adjacent to the place of the 1st crystal 13 and original horizontal planes are covered with the 1st and 2nd crystal layers 13 and 14. In this way, repetitions of these growths permit the 1st and 2nd crystals 13 and 14 to grow respectively while holding stepped forms on the GaAs substrate 11 and diffraction gratings 15 are formed by two kinds of crystals having different refractive indexes.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a transducer with a high frequency band characteristic and enhanced distance resolution and measurement accuracy by controlling a phase and an amplitude of a voltage applied to respective vibrators. SOLUTION: Cylindrical piezoelectric ceramic vibrators 1, 2 whose resonance frequencies are set with a slight deviation are stacked in two stages and they are combined with an umbrella type reflector 5. In order to slightly deviate the resonance frequencies of the vibrators, six lead balls 3 are adhered on a center line of an outer circumference of the vibrator 1 at an equal interval to add the mass of the vibrator 1 in a couple of the cylindrical piezoelectric ceramic vibrators 1, 2 of the same specifications so as to reduce the resonance frequency of the vibrator 1. The resonance frequency of the vibrator 1 is set to 30.664kHz and the resonance frequency of the vibrator 2 is set to 31.336kHz.  In the case of exciting the vibrators 1, 2 with a voltage at the same phase, the peaks of the respective resonance frequencies of the vibrators 1, 2 remain as they are, but the part between the peaks provide a flat frequency band characteristic thereby realizing the broad band characteristic of the ultrasonic wave transducer.
