Title: Caisson type pile method making use of packed concrete
Inventor: SADATSUKA MASAYUKI
IPC: E02D17/02
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a caisson type pile method making use of packed concrete capable of eliminating voids between earth retaining material and bedrock hole wall, eliminating a backing material and carrying out simple execution in sound work environment. SOLUTION: Water permeable ring shaped bags 20 are arranged along a hole wall of an excavated hole to cast concrete. Water is dewatered by casting pressure to form packed concretes 21. Repeating the constitution, the packed concretes 21 are piled up and down to use them as an earth retaining material. The bag is swelled in a state to project onto the outside of a ring, and it is tightly contacted to the hole wall and is dewatered to harden. By the constitution, in a caisson type pile method for a caisson type pile and shaft excavation, the collapse of a bedrock hole wall is prevented, the conventional execution of the backing material can be eliminated, and execution with safe and high economic efficiency can be carried out. Since water is only permeated, the sound work environment can be realized.

Title: Trawling operation and apparatus therefor
Inventor: KINOSHITA HIROMI
IPC: A01K73/02
Filed: 1988-12-12
Abstract: PURPOSE:To improve the form of a net in trawling and reduce the load in hauling by using plural pennants having nearly equal lengths, shortening at least one of the pennants in trawling and almost equalizing the length of each pennant in hauling. CONSTITUTION:A pennant ring 20 is connected to a trawling net via an otter board and an otter pennant. A pennant 8B having a length shorter than the pennants 8A and 8C is passed through a central opening 21 via an auxiliary wire 13. In the trawling, all pennants except for the pennant 8B connected to the otter board are moved backward along the auxiliary wire 13 via the pennant ring 20 to vary the distance to the trawling net. In the case of hauling, the restriction of a stopper 14 is released by the removal of the otter board, the pennant 8B is exclusively moved backward by the pulling force via a detour rope 9 and the distances to the trawl net become almost equal to each other.

Title: Optical head
Inventor: MIURA MASAFUMI
IPC: G11B7/09
Filed: 1986-12-29
Abstract: PURPOSE:To decrease the number of parts and to reduce the weight of a movable part of an optical head by using a magnetic circuit of an optical head feeding linear motor also to a tracking drive magnetic circuit and a focusing derive magnetic circuit. CONSTITUTION:When a current flows to a convertible coil 16 set in a bias magnetic field of a magnetic circuit 9, the force of the disk radius direction is produced to drive a main body base 2 along a guide shaft 3. Thus the coil 16 functions to feed an optical head 1 and drives a focusing action. When a control current flows to a focusing coil 8, the up-down force is produced since a lower winding part is set into the bias magnetic field of the circuit 9 to perform the focusing drive. Thus it is not needed to provide both focusing and tracking driving magnetic circuits to the head 1 and therefore the structure of the head 1 is simplified.

IPC: B42D15/02
Filed: 1989-12-04
Abstract: PURPOSE:To prevent the possibility that personal information may be printed for a wrong address by a method wherein the address writing surface and the secret message surface of a postcard paper material are positioned on the same surface. CONSTITUTION:In a postcard paper material 1, a half-size paper material 1b, the length of which is approximately one-half the long edge of a postal card-size paper material 1a, is formed continuously to the postal card-size paper material 1a via a fold line X in the longitudinal direction thereof; the paper material 1 is folded at the fold line X; and the surface of a part of the postal card-size paper material 1a and the surface of the half-size paper material 1b, which abut with each other, form secret message surfaces A, B serving as a secret letter. The surface of the postal-card paper material 1a other than the part forming the secret message surfaces A, B forms an address writing surface C. Therefore, since the address writing surface C and the secret message surfaces A, B are positioned on the same surface in the state that the material 1 is not folded at the fold line X, both an address and information for a secret letter can be written at a time respectively on the address writing surface C and on the secret message surfaces A, B as large in area as a normal postal card. These are written on the same surface as shown by a figure. In this manner, there is no possibility that information may be written with a wrong address.

Filed: 1987-12-11
Abstract: PURPOSE: To eliminate the need of an independent shutter and to obtain a panel shutter requiring no adhesive by fixing a board mounting a semiconductor element and electrodes to a frame and covering the electrodes openably as well as the board with the panel shutter. CONSTITUTION: A panel shutter 19 us opened/closed freely by a rest spring 14 to protect a PCB 11 and electrode terminals 12. When an IC card part 1 is inserted into a connector part 2, the panel shutter 19 abuts against an internal terminal 21 and slides backward. Consequently, the electrode terminal 12 on the PCB 11 emerges to be connected with the pole spring 22 of a connector thus operating an IC card electrically. The rest spring 14 of the panel shutter is elongated but when the IC card part 1 is drawn out from the connector part 2, the panel shutter 19 is reset through contraction of the spring 14. Since the panel shutter is integrated, manufacturing cost can be reduced due to decrease in the number of parts and since no adhesive is employed, the shutter functions reliably thus enhancing the reliability of the IC card.
