Title: Bedrock probing method
Inventor: ISHIYAMA KOJI
IPC: G01V9/00
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a bedrock probing method capable of easily and securely predicting geological features based on measuring data of a hydraulic system mainly when drilling a hole by a hydraulic rock drill. SOLUTION: Hole drilling energy indicating energy amount required for drilling a bedrock per unit volume is calculated by corresponding to hole drilling distance when the bedrock to be probed is drilled by the hydraulic rock drill 2 to predict the property of geological features based on the hole drilling energy. In the calculation of the hole drilling energy, impact energy is first calculated from a pressure receive area of a piston of a hydraulic cylinder device giving an impact when drilling the hole, a stroke length of the piston, and an impact pressure. Next, hole drilling energy is calculated from impact energy, the number of striking per unit time, hole drilling speed, and a hole cross sectional area for drilling the hole.  When the hole is drilled, a feed pressure for pressing a bit of the hydraulic rock drill 2 against the bedrock is kept substantially constant during drilling of the hole.

Title: Fishhook
Inventor: DOI TOMIYUKI
IPC: A01K83/00
Filed: 2000-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent a fishline wound around a fishhook from being moved in the shaft circumferential direction of the fishhook. SOLUTION: This fishhook is characterized by a convex line part 7 which extends in the axis direction, becomes a contacting part with the fishline m, and is formed as a whirl-stop of the fishline m to be bound, at the center of the back surface of a line-binding part to be bound by the fishline m, and concave line parts 8 and 8 which become uncontacted parts with the fishline m, and are formed at the right and left of the convex line part 7. As a result, the wound fishline m1 of the fishline m bound on the line-binding part 6 is pushed by the convex line part 7 which is the whirl-stop to prevent the wound fishline ml from being moved in the shaft circumferential direction of the fishhook.  Especially, by forming the concave line parts 8 and 8 as the uncontacted parts with the fishline m at the right and left of the convex line part 7, the contact or the convex line part 1 with the fishline m at the center of the back surface of the line-binding part 6 is made certain by aggressively excluding the positions capable of contacting with the fishline m except the convex line part 7.

Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a superior piezoelectric oscillation gyro exhibiting a stable high sensitivity, using an easily manufacturable piezoelectric oscillator having a fixed inter-electrode capacitance having no need of adjustment in manufacturing processes.

The piezoelectric oscillation gyro is manufactured, using this oscillator. From its sensitivity characteristics investigated, it was found that the sensitivity variation is less than that of a piezoelectric oscillation gyro made using the conventional oscillator made of the circular columnar piezoelectric ceramics, without applying the HIP process and heat treatment.
