Abstract: PURPOSE:To drill a thin continuous groove by driving a wire saw tensely laid around pulleys respectively arranged on guides by means of a hydraulic motor, and adjusting an interval of the pulleys and an interval of the wire saw by means of a width adjusting mechanism. CONSTITUTION:A driving carriage 3, a regulating carriage 4 are resectively arranged on guides 2, 2', and a driving pulley 3c, a fixed pulley 4a and an adjusting pulley 4b are arranged therein. A wire saw 5 is tensely laid around the respective pulleys. The hydraulic motor of the driving carriage 3 is driven so as to rotate the pulley 3c, and the wire saw 5 is circumferentially turned in the lenghwise direction so as to perform drilling. Then the driving carriage 3 and the adjusting carriage 4 are elevatably moved independently, and a thin groove nearly equal to the width of the wire saw 5 is drilled downward in order from the surface layer part to the deep layer part of a water cut-off wall construction scheduled place A. Further, when a layer of coarse particle size is reached, the width of the respective pulleys are adjusted by means of a pulley width adjusting mechanism 7 so as to adjust to spread the width of the wire saw 5. Hence, the thin groove can be drilled without improving the ground.

Abstract: PURPOSE:To improve the relative frequency characteristic, to reduce a noise and interference by arranging a light shielding plate in a band shape corresponding to the direction perpendicular to a track in the optical path of a reflected light from an information recording medium and reproducing the information by detecting a luminous flux without being shielded. CONSTITUTION:A band shaped light shielding plate 1 is arranged in a reflected luminous flux from a recording medium corresponding to the direction perpendicular to the track direction.

Title: Melting method and device for road material for executing road compartment line
Inventor: TERAOKA ATSUO
IPC: E01C23/24
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To immediately supply a molten road material on a road as much as the required quantity when it is required by charging the road material into a heating cylinder which has a rotatable screw in its interior, and by melting it while transferring it to the forefront side of the heating cylinder by the rotation of the screw. SOLUTION: Workers go to a purposed working site by automobile, and charge powdery road material 14 inside a heating cylinder 5 of a device which has been installed on the bed through a supply port 7. When a screw 6 is rotatingly driven, the powdery road material 14 is sent to the forefront side inside the heating cylinder 5 as the screw 6 is rotated while being melted, and the molten road material is discharged from the discharge port 8 of the heating cylinder 5. The discharge quantity at that time is regulated by the change of the rotating speed of the screw 6. Thus, the molten material can be immediately supplied on the road as much as the required quantity when it is required, and also since fire is not used, the equipment for safety precaution can be dispensed with, and the safety during the traveling on a road can be maintained.

Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent fog at a low temperature without providing an expensive surface-potential sensor by controlling the output of an electrostatic charger in the case the temperature of the surface of a photoreceptor is lower than a reference temperature, thereby compensating for a decrease in electrostatic charge potential. SOLUTION: When a main power source is turned on and printing is started, the temperature of the inside of the device is detected based on a detection signal from a temperature sensor 13. When the temperature T1 of the inside of the printer is lower than a specific reference temperature T0, a timer is started and a grid voltage Vg is set to a voltage value Vg1+A, which is higher than an ordinary grid voltage value Vg1, the time the timer expires. The set value is outputted to an electrostatic charging circuit 2c and consequently the circuit 2c applies a voltage of Vg1+A to a grid electrode 2b. Also, when the started timer expires, the grid voltage Vg is set to the ordinary grid voltage value Vg1.

Title: Carriage mechanism for floppy disk
Inventor: KAWAKAMI CHIKAHISA
IPC: G11B21/02
Filed: 1986-12-25
Abstract: PURPOSE:To prevent the production of sound noise due to position deviation of a carriage caused by thermal expansion and an intermittent contact between a belt holder and the carriage by devising only one end of the belt holder to be fixed to the carriage in a carriage mechanism of the steel belt type. CONSTITUTION:A belt holder 17, while its one end is fixed to a carriage 10 by a screw 18 and its other end is not fixed, is brought into contact closely to the side end of the carriage 10. In this case, the belt holder 17 is formed to be bent by an angle THETA in advance and is brought into contact closely so as to be pressed in the direction of the side face of the carriage 10 in case of being mounted onto the carriage 10. Thus, the vibrating state that the belt holder is parted from or brought into contact with the side face of the carriage 10 intermittently while the carriage 10 is being moved, does not take place. Thus, the deficient state due to thermal expansion is prevented and the production of noise due to intermittent contact is avoided.

Abstract: PURPOSE:To prevent that a junction leakage current and a dielectric breakdown defect are caused at a MIS transistor by a method wherein a polycrystalline silicon layer which has been connected electrically to a gate electrode is formed under a sidewall and it is used as a stopper. CONSTITUTION:A silicon dioxide film 6 is etched wholly by an anisotropic etching operation; it is left as sidewalls 6A-1, 6A-2 only on side faces of a gate electrode 3. At this etching operation, the silicon dioxide layer 6 and a polycrystalline silicon layer 4 can take a selective ratio sufficiently; the polycrystalline silicon layer 4 acts as a stopper for the etching operation. The surface of a P-type semiconductor substrate 1 is not exposed directly to a plasma etching operation; there is no fear that it is damaged and contaminated. Then, an ion implantation operation is executed through the polycrystalline silicon layer 4; arsenic is implanted; N-type high-concentration regions 7-1, 7-2 are formed. An electric charge which has been injected into the gate electrode 3 on a gate oxide film 2 at this time is discharged through the polycrystalline silicon layer 4 through a jig at an ion implantation apparatus which fixes a wafer and is grounded. As a result, there is no fear that the gate oxide film 4 is destroyed. Then, the polycrystalline silicon layer 4 which has been revealed is etched and removed.
