Title: Reinforcing method for concrete pile head
Inventor: KAIDO EIMATSU
IPC: E02D5/30
Filed: 1980-08-28
Abstract: PURPOSE: To strengthen a tightness between a steel pipe and a pile head, by a method wherein the steel pipe is brought into contact with the head part of a concrete pile, and they are pressed for mating in a manner to heat it by means of a toroidal-shape burner.  
     CONSTITUTION: A mating end 2a of a steel pipe 2, spread in a taper, is brought into contact with a head part of a concrete pile 1 for mating. A toroidal burner 3 concentrically mates in a play outside the steel pipe 2, and a gas jet nozzle is ignited to heat the steel pipe 2 by means of gas flame. The steel pipe 2 is then pressurized from above, and this facilitates lowering of the steel pipe resulting from the thermal expansion created by heating and the deformation due to the pressurization and enables mating of them. The current heating temperature confines itself to rise up to about 300°C at the heating source of the steel pipe so that the concrete is prevented from being influenced by a heat.

Title: Device for drilling hole in bedrock
Inventor: TSUCHIYA TOSHIRO
IPC: E21C25/06
Filed: 1995-04-20
Abstract: PURPOSE: To prevent wear and tear of or damage to a guide rod due to contact with a drilling bit. CONSTITUTION: A guide rod 60 is inserted into a hole 17 which has been formed in a bedrock 19 to fix a frame 1. And a drilling rod 4 is rotated to gradually advance a drilling bit 3, whereby a hole is formed adjacent to the hole into which the rod 60 has been inserted. As the formation of the hole progresses and the distance from a bracket 70 to the bit 3 gradually increases, the drilling rod 4 is bent toward the hole 17 and largely bent when the bedrock 19 is very hard so that the peripheral portion 3a of the bit 3 is brought into contact with the rod 60. Since the rod 60 is rotatably supported by a bearing 5a in a bearing case 5 through an axis 25, the rod 60 also is rotated by contact with the bit 3.  Thus frictional force between the rod 60 and the peripheral portion 3a of the bit 3 is extremely small, and hence wear of the rod 60 and bit 3 rarely occurs and breakage thereof can be avoided.

Title: Reading data correction system for magnetic tape
Inventor: KANATSU JIYUN
IPC: G06F11/10
Filed: 1979-09-18
Abstract: PURPOSE: To secure a correct operation of the error detector using the CRC, by detecting whether the bits are the space or the data from the synchronism of the data in case the bits read out are all 0.  
     CONSTITUTION: In case only one bit among the bits in a lateral row of the paralled track is 1 with the rest bits set all to 0, all bits are turned to 0 if the only one bit features the error 0. In such case, the data input is interrupted to the data buffer part 9 and the synchronizing circuit 10, and thus no data space signal is supplied to the omission detecting circuit 16 from the circuit 10. And the omission signal is supplied to the gate 11 by the data space signal. As a result, the gate is closed to regard the data of 0 of all bits, and this data is sent to the parity detecting circuit as well as the correction gate circuit 14 each. Then the data receives a checking by the CRT system to receive a correction of the error 0. In such way, the data can receive a correction to be a correct data without being regarded as the space.

IPC: G11C11/14
Filed: 1984-06-12
Abstract: PURPOSE:To eliminate the defective operation of a magnetic bubble memory element by forming an insulated layer on a magnetic garnet film when a drive pattern is formed, producing an eaves-shaped resist pattern with use of a prescribed resist and forming the level difference part of a gentle slope of an anisotropic dry etching process with said resist pattern used as a mask. CONSTITUTION:The 1st insulated layer (SiO2) is formed on a magnetic garnet film 1, and a gold conductor pattern 3 is formed on the insulated layer. The 2nd insulated layer 4 (silicone resin) is provided on the pattern 3. Then a resist of naphtoquinone diazid is applied on the layer 4 and baked. Then the resist is dipped into aromatic hydrocarbon (chlorbenzene) to obtain a resist pattern 11 having an eaves-shaped projection part 12. This pattern 11 is used as a mask to perform a reactive sputtering etching process with use of Freon gas. Thus a gentle level difference part 13 is obtained. The 3rd insulated layer is formed on the part 13 to obtain a dual spacer. Then ''Permalloy(R)'' is vapor-deposited on the dual spacer to form a drive pattern by a sputtering etching process. Thus no ''permalloy(R)'' remains at the part 13. This eliminates the defective operation of a magnetic bubble memory element.
