Title: Fixing member with enlarging member
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/08
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To attain positive after-enlargement by crack formation at the time of expanding a drilled hole easily at a low cost by providing an enlarging member with a stopper brought into contact with a front end part of a fixing member. SOLUTION: A fixing member 1 has a shaft 2 provided with an external thread 3 at a rear end part 4, and an enlarging area formed of an enlarging member 7 entering a longitudinal slit 5. The enlarging member 7 has a tooth line 8 and is held by a slidable holding member 12. In order to prevent the enlarging member 7 from sliding toward the rear end part to cause pre- enlargement at the time of driving the fixing member 1 into a drilled hole, the enlarging member 7 has a stopper 10 brought into contact with a front end part of the fixing member 1. The enlarging member 7 is put out of motion in the drilled hole along with the shaft 2 by axial sliding generated by screwing a nut 17. Even when expansion of the drilled hole is generated by crack formation, axial sliding of the same effect is generated.  The expansion of the drilled hole is compensated by the increase of radial fixing of the enlarging member 7.

IPC: G11B21/02
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To thin a spindle structure and an actuator structure and make an assembly work easy by forming in an outer circumferential part of a spindle hub a groove to which an inner circumferential part of a clamp ring is fitted. SOLUTION: An inner circumferential face 12a of a clamp ring 12 is fitted in a groove 3a formed in an outer circumferential face of a spindle hub 3. The groove 3a has a face inclined in an axial direction. A magnetic disk 2 is pressed by a force generated when the inclined face of the groove 3a is engaged with the inner circumferential face 12a of the clamp ring 12. The pressing force unites the clamp ring 12, the magnetic disk 2 and a spacer 11 and fixes to the spindle hub 3. When shrink fitting is employed, the clamp ring 12 is heated to approximately 150-200 deg.C beforehand, and assembled in a heated/expanded state. In the case of press fitting, a difference of an inner diameter of the clamp ring 12 and an outer diameter of the spindle hub 3 is made smaller than in the shrink fitting method, and moreover, a depth of the groove 3a is reduced.

Title: Electron rays detector
Inventor: HATTORI HIDEO
IPC: H01J37/244
Filed: 1984-12-31
Abstract: PURPOSE:To cut the high voltage of the secondary electron photomultiplier for an electron rays detector and fully apply the output signals to the next stage amplifier by applying driving voltage to an anode during non-measurement period only. CONSTITUTION:The switch 7 of this secondary electron photomultiplier 1 is set to OFF during scanning period and is set to ON during retrace line period. While the switch 7 is being set to ON, charge current is prevented from flowing into an amplifier A by a diode 10 and a condenser 8 is charged until the voltage of a power supply 6 is reached. During scanning period, the charge voltage of the condenser 8 is applied to an anode 1a and all electrons generated in a dynode 1b are sucked by the anode 1a. Current flows toward the anode 1a and the condenser 8 is discharged. This current is the output current itself of a secondary electron photomultiplier 1 and is compensated by the discharge of the condenser 8. In other words, the output current of the secondary electron photomultiplier 1 flows into the amplifier A through the diode 10 and the condenser 8 and the output signals are input fully input to the amplifier A including DC components.

Title: Incomplete combustion preventive unit for gas appliance
Inventor: ARAI AKIRA
IPC: F23D14/72
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To shut OFF the supply of gas when an incomplete combustion occurs and to prevent an accident by so setting a burner port as to lift as compared with the standard burner port, and providing a flame rod for monitoring the flame above the port. SOLUTION: Three burner units 10 are aligned to form a combustor. The burner 10a of the three burners 10 is so formed that the two burner ports 12a disposed at this side base are formed in a small diameter as compared with other standard burner port 12, a flame rod is opposed above the port 12a to monitor the flame. When the combustion unit incompletely burns, the port 12a of the burner 10a is formed in a smaller diameter than that of the other standard port 12, and hence the flame formed at the port 12a is lifted prior to the flame formed by the standard port 12. The rod detects it to close a solenoid valve interposed at the gas supply passage to shut OFF the supply of gas to the combustion unit and to immediately stop the combustion.

Title: Vehicular seat
Inventor: NAWATA TAKEMI
IPC: B60N2/42
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To absorb an impact without bending a seat back itself on the way at the vehicular collision time from a backside. SOLUTION: A flange 44 is formed on the upper end edge of a lower arm 34. In the lower arm 34, the strength of an upper part is set higher than the strength of a lower part. A brittle part 46 is formed on the intermediate part of the front/rear direction of the lower arm 34. When an impact with a prescribed value or more is added toward a vehicular rear side at the vehicular collision time from a backside, the lower arm 34 starts a deformation with the brittle part 46 as a start and absorbs the impact. The deformation of the lower arm 34 is restrained effectively by the flange 44 for a load from the rearside acting to a seat back 12 by a loaded baggage at the vehicular front collision time.

Filed: 1992-10-16
Abstract: PURPOSE:To reduce the deterioration of a contrast caused by the ruggedness or irregular color of the surface of a slab so as to inexpensively inspect the slab surface for defects with high sensitivity by providing a lighting device, diffusing device, image pickup device, and picture displaying device. CONSTITUTION:The irradiating light made incident upon a diffusing plate 4 is radially spread at an emitting point and, since a lighting device 3 provided as a light source has a rod-like shape, the incident angle and intensity of the incident light are diversified and the light transmitted through the plate 4 (diffused light) becomes uniform and has a uniform directivity. In addition, since the line of sight of a camera 5 is extended and a point source is necessary provided in the direction in which the irradiating light is regularly reflected, a uniform and bright picture can be obtained. Therefore, the generation of parts from which regularly reflected light is obtained and no regularly reflected light is obtained due to the ruggedness of the slab surface. In addition, when the lighting device 3 and camera 5 are deviated from optically symmetrical positions, the quantity of regularly reflected light from the slab surface decreases and the contrast between a defect 2 and defectless defectless part disappears. In order to perform optimum defect detection, therefore, the device 3 and camera 5 are positioned at optically symmetrical positions with respect to a normal to the slab 1.
