Title: Information erasing device for optical information recorder
Inventor: UENO OSAMU
IPC: G11B7/125
Filed: 1987-12-29
Abstract: PURPOSE:To facilitate design and adjustment by forming an elliptical laser spot by utilizing the large astigmatic difference of a gain waveguide type semiconductor laser, and adjusting the parameters of a collimator lens and an objective lens. CONSTITUTION:The adjustment of the collimator lens 2 is performed so as to set in parallel laser beams emitted from a light emitting point Px on a plane xz. At this time, the length of the laser spot in a direction of (x) converged on a recording medium 4 by the objective lens 3 goes to length l1 decided by the focal distance of the objective lens 3 and the diameter of an incident beam to the objective lens 3. Meanwhile, since a light emitting point Py on a plane yz is deviated by the astigmatic difference DELTAz from the light emitting point Px on the plane xz, the laser beam emitted from the collimator lens 2 is converged at the front of the recording medium 4, and the length of the laser spot in a direction of (y) goes to l. Thus, it is possible to perform the design and the adjustment easily by forming the elliptical laser spot with simple constitution by utilizing the large astigmatic difference DELTAz of the gain waveguide type semiconductor laser.

Title: Manufacture of electrodeposited grinding stone
Inventor: IMAI TOMOYASU
IPC: B24D3/06
Filed: 1987-12-28
Abstract: PURPOSE:To reduce the peripheral run-out of an electrodeposited grinding stone to improve its surface by successively pressing abrasive grains on a soft metallic layer on the peripheral face of a grinding stone core by the peripheral face of a pressing roll, and temporarily fixing them on the layer to arrange the sharp edges of the abrasive grains on a cylindrical face being in common axial relation with the axis of the grinding stone core. CONSTITUTION:The peripheral face of a grinding stone core C is formed of a soft metallic layer M having proper thickness, and the grinding stone core C and a pressing roll 1 are rotatably provided so that their peripheral faces may be mutually opposite with a gap d between them having a fixed dimension. Abrasive grains G are supplied into the gap G from the side where the peripheral faces of the core C and the roll 1 approach to each other as they are rotated in mutually opposite directions, and held between their peripheral faces, and then successively pressed on the soft metallic layer M on the peripheral face of the grinding stone core C by the pressing roll 1 and temporarily fixed onto the layer M. The peripheral face of the core C having the temporarily fixed abrasive grains is then electroplated to make the abrasive grains G firmly adhere onto the soft metallic layer M. Thus an electroformed grinding stone having less peripheral run-out and an excellent surface can be manufactured.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten the term of works by conducting waterproofing works without waiting the hardening of concrete and eliminating the need for scaffold assembly and removal works for waterproofing works. SOLUTION: A sheet 1 being bulged in an arched shape by air pressure and conducting timbering and being used for molding a building frame is employed as forms for forming arched building-frame concrete 12. Since a waterproofing sheet 13 can be laid on the sheet 1 for molding the building frame before the sheet 1 is bulged, a work platform for executing the waterproofing sheet 13 is unnecessitated. Since the waterproofing sheet 13 is brought to an integrally joined state with the arched building-frame concrete 12 formed by spraying concrete onto the outer circumference of the waterproofing sheet 13, the placing of the arched building-frame concrete and the waterproofing works of the arched building-frame concrete are conducted simultaneously.

Also, while the approximation function coefficient for estimating the fastening force is obtained from the increased amount of the fastening force obtained in every torque pulse, the number of impacts estimated to attain a desired fastening force is calculated 115 from the approximation function for estimating the fastening force. A drive timing for driving a power source controlling electromagnetic valve 120 is judged 116 from the obtained number of impacts estimated to attain the desired fastening force and the number of excessive impacts obtained from the experiment.
