Title: Drawing method for existing foundation pile
Inventor: OKAMOTO ATSUO
IPC: E02D9/02
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of an underground buried object near a foundation consolidation material and the vibration/noise damage to surrounding inhabitants by digging the ground along a casing screw covered on the head section of an existing foundation pile, cutting off the tip section of foundation pile from the foundation consolidation material, then hoisting and drawing the foundation pile. SOLUTION: A hole 1a is drilled to expose the head section 2a of a foundation pile 2 below the surface of the ground 1, a casing screw 3 is covered on the head section 2a of the foundation pile 2, and the ground 1 is gradually drilled along the foundation pile 2. When the ground 1 is drilled to the tip section 2b of the foundation pile 2, i.e., a portion fixed by a foundation consolidation material 6, the foundation consolidation material 6 around the tip section 2b is cut out, and the foundation pile 2 is cut off. The casing screw 3 is lifted and drawn from the ground 1. The foundation consolidation material 6 stuck to the lower end section of the foundation pile 2 is cut out when the foundation pile 2 is drawn, a nearby underground buried object is not damaged, and no vibration/noise damage is applied to surrounding inhabitants.

Title: Recorder, recording system and dubbing method
Inventor: UCHIUMI YOSHIMASA
IPC: G11B27/22
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To lighten a user's burden and to enhance convenience by discriminating whether an input of character information is finished or not upon detection of a change into the next program in the midst of dubbing and automatically controlling a recording operation into the standby state in the case of unfinishment. SOLUTION: When an audio signal supplied to an analog or digital input terminal 17 or 21 from a CD player, etc., is dubbed on an MD 90, a program number is monitored via a silence detecting part 22 or a digital interface part 25 by a system controller 11. Upon detection of a change of the program number, whether an input of character information is finished or not is discriminated based on whether an operation of a decision key on a remote commander 29 or an operating part 19 is over or not. If not, a command of reproduction on standby is issued to the CD player. When the input of the user's character information is finished, information of inputting the character information is recorded in a UTOC sector of the MD 90, and then the CD player is released from its standby for reproducing.

Title: Vibration detector
Inventor: MATSUSHITA HIDETOSHI
IPC: G01V1/16
Filed: 1982-07-30
Abstract: PURPOSE:To provide a vibration detector with an excellent reliability in the detection of vibration and inclination with a higher contact pressure against a fine vibration by magnetically maintaining the contact between an armature and a case depending on vibration and inclination generated in a precision equipment. CONSTITUTION:A magnetic flux 22 is generated in a magnetic circuit made up of a cylindrical body 16, an armature 18 and a case 14 to allow the armature 18 to be maintained horizontally due to the balanced magnetic circuit and the gravity, keeping an interval D with the case 14. When a machine body 12 is vibrated or inclined, the case 14 tilts and the periphery 18a of the armature 18 contacts the inner surface 14a of the case 14 due to the gravity to break the balance of the magnetic circuit, so that it is attracted and retained onto the inner surface 14a of the case 14 by a magnetic attraction force. This can heighten the contact pressure at the contact section between the armature 18 and the case 14 to improve the detection sensitivity of a detector section 21 while providing an exact electrical signal thereby protecting precision equipment or the like from the inclination and vibration.

Title: Recorder
Inventor: HORI KENJIRO
IPC: B41J29/38
Filed: 1993-06-04
Abstract: PURPOSE:To reduce the power consumption in an image recording means consuming a relatively large amount of electric power even in a no-load state by a method wherein when a recorder is in a standby state without an input of image information to a control means, a power supply from a second power source means to the image recording means is interrupted. CONSTITUTION:A recorder 1 receives coded image information from an external information processor 2 and outputs image data to an image processor 4. When the recorder 1 is in a standby state in which it does not conduct a printing action and receive information from the external information processor 2, a data control part 3 is supplied with an electric power from a battery 7 that can be charged to make a RON signal to a semiconductor relay 9 false. With the RON signal in a false state, the semiconductor relay 9 is brought to an interrupted state, thereby interrupting an AC power supply to a switching power source 6. Therefore, because the outputs V1, V2 of the switching power source 6 are zero, the image processor 4 and an image forming device 5 are in an unactuated state.

IPC: B29C45/52
Filed: 1990-05-24
Abstract: PURPOSE:To discover the abnormality of a back-flow preventive device, a screw or a cylinder easily even at the initial stage of the start of mass production when there is the abnormality by interrupting the flowing of a resin toward a mold as pressure is left as pressure in the progressive direction is applied to the screw after the completion of a dwell process during an injection molding cycle and detecting the status of the forward movement of the screw. CONSTITUTION:A dwell process during an injection molding cycle is executed by applying pushing force in the progressive direction to a screw 3 under the state in which a nozzle closing valve 7 is opened. When the state is kept for a specified period and the dwell process is completed, the nozzle closing valve 7 is closed as pressure in the progressive direction is left as it is applied to the screw 3, thus interrupting the flowing of a molten resin toward a mold 1. When the advanced speed VA of the screw 3 is detected from the status of the forward movement of the screw 3 under the state of such flowing interruption, concretely the closing time of the nozzle closing valve 7 after the completion of dwell and the detecting value exceeds a specified set reference value VS, whether or not a check valve 9 is operated normally can be detected when an abnormal signal is emitted.

IPC: H04B7/26
Filed: 1993-06-04
Abstract: PURPOSE:To make the revision of a scramble code possible during communication for a short communication interrupt time even under the occurrence of interference or the like independently of the line operating state. CONSTITUTION:A base station generates a random number during communication and generates the random number and an original code designation signal 501 to the mobile station and generates a scramble code based on the random number and an original code designation signal 501. The mobile station generates a scramble code based on the received random number and the designated original code, sends a scramble code generation end signal 502 to the base station and starts the detection of a synchronization establish signal (510). Upon the receipt of the signal 502, the base station sends the synchronization establish signal 503 to the mobile station in place of a communication signal. When the mobile station detects the synchronization establish signal 503, the mobile station makes re-synchronization processing (508) and when re- synchronization is established, the mobile station uses the scramble code generated precedingly and the communication is scrambled between the mobile station and the base station.
