Title: Tool holder
Inventor: BUORUFUGANGU SHIYUMIITO
IPC: B23B31/22
Filed: 1989-12-20
Abstract: PURPOSE: To engage a shaft rigidly by forming a shallow long groove in a hole of a receiving part of a tool holder for a hammer drill, and by inserting an insert shaft of an impact tool having a long rib with length abutting to the long groove into the hole of the receiving part. CONSTITUTION: When a hammer drill is used for accurate drilling work, a drill chuck is inserted into a receiving part 3 of a tool with an adapter shaft 15. The adapter shaft 15, like usual tool for impact drilling, is rotated and carried with the hammer drill by a rib 8 and a longitudinal groove 16. Advantageously, a long rib 18 formed to a given size by grinding comes into contact with a long groove 12 tightly, and therefore the adapter shaft, 15 is accurately centered in a hole 7. Power of an impact device of the hammer drill is blocked advantageously during drilling work. But, length of the shaft 15 can be shortened so that an end part of an impact member 13 does not project to the shaft 15. As a result, only rotating motion is transmitted to an adapter.

Title: Leakage detecting method
Inventor: RIYOU GIYOUKEI

Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a leakage detecting method capable of making high- accuracy detection and having less effect of the environment regardless of the material of a buried pipe in the survey of the leakage position of the buried pipe. SOLUTION: The gas in the detection zone of a water service pipe 1 is sucked by a vacuum pump 6 to decompress the air pressure below the atmospheric pressure, preferably to -0.01 MPa or below, air flows into the pipe 1 from a leakage section, and a leakage sound is generated by an air current vortex in the pipe 1 and the collision of an air current with a pipe inner wall. The leakage sound propagated in the pipe 1 and on the pipe wall is detected by detectors 8, 9 and converted into electric signals, and the electric signals are amplified by leakage detector child machines 12, 13 and transmitted to a leakage detector parent machine 14. The transmitted signals are analyzed to calculate the time difference until the leakage sound reaches the detectors 8, 9 from the leakage position, and the distances from the detectors 8, 9 to the leakage position is calculated.

Said sample is exposed to plasma composed of the oxygen atmosphere for thirty min, and a layer 3 treated with oxygen plasma is shaped near the surface. The thin-film 2 consisting of Y1Ba2Cu3O7-x is formed onto the layer 3 treated with oxygen plasma through a sputtering method again. The process is repeated in a number of times such as one hundred times, thus forming multilayer superconducting thin-films in 1mum made up of one hundred layers.

Title: Heat insulated rice cooker
Inventor: TSUJI KENICHI
IPC: A47J27/00
Filed: 1994-12-28
Abstract: PURPOSE: To maintain proper heat insulation for cooked rice, give a proper alarm about an excessive heat insulation time and improve operability, in a heat insulated rice cooker capable of making a selection between high temperature heat insulation and low temperature heat insulation. CONSTITUTION: A heat insulation means 65 has two heat insulation processes consisting of a high temperature heat insulation process and a low temperature heat insulation process. In addition, the means 65 has a low temperature memory for storing a heat insulation process at low temperature, and a re-heating time setting means for setting the re-heating time of re-heating means 7, 64 and 65 to be longer, when the low tempreature heat insulation memory is set, compared with the case where the memory is not set. As a result, re-heating time at a low temperature heat insulation process is extended beyond re-heating time at a high temperature heat insulation process, based on the contents of the low temperature heat insulation memory stored according to the execution of the low temperature heat insulation process.  According to this construction, the re-heating time during the low temperature heat insulation process is set to be longer than the re-heating time during the high temperature heat insulation process, and to give a difference in a supplied calorific value between both of the processes, thereby correcting a temperature difference at the start of a re-heating process as much as possible. Consequently, a difference in the temperature of cooked rice between both of the processes is almost eliminated at the time of completing the re-heating process.

Title: Superconductive wire with high critical current density and its manufacture
Inventor: HAGINO SADAAKI
IPC: H01B12/04
Filed: 1987-12-25
Abstract: PURPOSE:To provide a superconductive wire having high critical current density by filling so that superconductive ceramic powder will be in a specific composition.

Less than 5mum of the thickness of this compressed orientation layer 2 admits only a critical current density Jc of 10<3>A/cm<2>, which should increase with greater layer thickness, but a layer 2 obtained by ordinary rolling or press has a thickness limit of 150mum. This allows simple aquisition of a superconductive wire having high critical current density.

Abstract: PROBLEM TO BE SOLVED: To provide the method for controlling a resistance welder which automatically detects the worn quantity of an electrode chip and outputs an electrode chip dressing signal and an electrode chip changing alarm, in the resistance welding method executing the pressurizing action of the electrode with an electrical servo motor. SOLUTION: In the resistance spot welding method executing the pressurizing action of the electrode with the electrical servo motor, at this time of changing the electrode chip to the new one, the idle pressurizing which does not insert the material to be welded, is executed, and the value at this time of an encoder included in the servo motor is read to execute the original point setting. Then, thereafter, in a series of the welding work, periodically the idle pressurizing which does not insert the material to be welded, is executed in the range of 10-100 hits, in which the wearing of the electrode chip does not remarkably progress, and the value at each time of the encorder is detected.  The difference between each value of the encorder and the original point, is calculated to calculate the worn quantity of the electrode chip, and this worn quantity is compared with a worn quantity which is necessary to the dressing of the preset chip tip part, or a reference value of the max. worn quantity, and when the worn quantity exceeds the reference value, the dressing signal or the changing alarm of the electrode chip is outputted. By this method, since the electrode stroke is kept to almost fixed distance, the extension of cycle time can be prevented.
