Title: Method of grinding diamond
Inventor: OTSUKA YASUHIRO
IPC: B24B9/16
Filed: 1986-03-26
Abstract: PURPOSE:To obtain a mirror surface without hair cracks being produced at an edge part, with high accuracy and with reduced production cost by pressing a diamond tool against a thin nickel film formed on a mirror-finished substrate, thereby performing grinding by means of the thin nickel film. CONSTITUTION:A nickel sputtering film 20 is formed on a donut-shaped glass plate 19 mirror-finished from a grinding plate 18. Mirror-finish grinding is performed while pressing a diamond tool against the rotating grinding plate 18 with grinding load applied on the diamond tool. As a result, the ground surface is finished to a highly accurate mirror surface copying the nickel sputtering film 20. In addition, since the grinding does not use diamond abrasive sand, a very sharp cutting edge free from hair cracks can be obtained. Further, since the grinding process can be performed without using expensive diamond abrasive sand and the fabrication and reproduction of the grinding plate 18 can be easily performed with etching technique and thin film forming technique, production cost can be reduced.

Title: Three-way solenoid valve
Inventor: NASU TAKESHI
IPC: F16K31/06
Filed: 1989-03-23
Abstract: PURPOSE:To prevent sticking of the three-way solenoid valve by disposing a ball between respective valve seats of inner and outer bases so as to assemble the inner base to outer base, and fixing at the end of a presser bar a plunger through which a pressure relief hole is to be formed, and holding the presser bar in a core via a sleeve. CONSTITUTION:A ball 22 serving as a valve is disposed between respective valves seats 21b, 23b of an inner base 23 and an outer base 21 so as to assemble the inner base 23 to the outer base 21, and a presser bar 36 capable of abutting to the ball 22 is held in the core 27 of the solenoid device via a sleeve 26 in such a manner that the bar is sealed from the valve portion, and, a plunger 35 through which a pressure relief hole 35d is to be formed is fixed at the end of the sleeve 36 and the back side of the plunger is sealed by a stopper 40. While electricity is not transmitted to a coil 29, the plunger 35 is located on the left side and the presser 36 retreats, and the ball 22 closes a discharge port 53 by a fluid pressure from an inlet port 51 and opens an outlet port 52. While electricity is transmitted, the ball 22 is pressed against the valve seat 21b by the presser bar 36, the inlet port 51 is closed and the outlet port 52 is communicated with the discharge port 53. Generation of sticking can thus be prevented.

Title: Detector for coefficient of slide friction of road surface
Inventor: NAKAYAMA MASAFUMI
IPC: G01L5/22
Filed: 1984-04-07
Abstract: PURPOSE:To achieve an accurate detection by inputting signals of the vehicle speed and the angle and speed of steering to compute these signals based on the reference steering torque operation data previously memorized to compare and compute the reference steering torque and the actual steering torque. CONSTITUTION:A vehicle speed signal (a), an angle of steering signal (b) and a speed of steering signal (c) are inputted into a computation circuit 8 which computes these signals (a), (b) and (c) based on the reference steering torque operation data A and B previously memorized and outputs a reference steering torque signal (d) to a comparison/computation circuit 9. Then, the comparison/computation circuit 9 compares and computes an actual steering torque signal (e) from a steering torque detection means 10 and the reference steering torque signal (d) as input signal. When the reference steering torque signal (d) corresponds to the steering torque on a dry asphalt road surface outputted, the coefficient of slide friction of the road surface in the actual running road with respect to the dry asphalt road surface is detected as a coefficient of slide friction signal (f) for the road surface.

IPC: G02B27/18
Filed: 1992-02-19
Abstract: PURPOSE:To repeatedly generate a phenomenon wherein a projection image appears and then disappears and to give a viewer a fantastic impression by providing a rotary prism so that its axis of rotation deviates from the axis of projection of a projection pattern. CONSTITUTION:When a circular plain no-design pattern is rotated by the rotary prism 5 in a triangular pyramid shape while its vertex 0 is aligned with an optical axis, its circular projection image which is split by the respective prism surfaces is projected so that its center rotates on a point O on the optical axis. In this case, the rotary prism 5 is provided so that its axis 0 of rotation deviates from the axis of projection of the projection pattern, so as the axis of projection passes through the prism surfaces P1, P2, P3, and P4 of different colors in order, a projection image by one prism surface appears and comes up on the projection surface so that it seems to follow a last different-color projection image; when it loses its sharpness and disappears by passing through a main projection surface, a next different-color projection image appears and disappears following the last image, so that this phenomenon is repeatedly generated.

IPC: B22D11/126
Filed: 1981-05-09
Abstract: PURPOSE:To prevent the deformation of steel ingots as far as possible with a compact device by clamping the steel ingot with an upper cutting blade and a clamping cradle, and moving a lower cutting blade thereby cutting the ingot. CONSTITUTION:As a traveling cylinder 20 is driven to extend, a taveling carriage 11 travels toward a traveling direction 22. Upon lapse of a set time, a clamping cylinder 14 is driven to extend, thereby lowering a frame 12 and an upper cutting blade 15. A steel ingot 21 is grasped by a pressure between the blade 15 and a clamping cradle 19, by which the clamping is completed. At this point of time, a cutting cylinder 18 and a return cylinder 37 are driven to extend. A lower blade holder 16 ascends and the ingot 21 is cut by the blade 15 and a lower cutting blade 17. During this cutting, the ingot 21 is held clamped by the blade 15 and the cradle 19 and therefore the deformation by the cutting of the ingot 21 is prevented as far as possible.

Filed: 1990-03-20
Abstract: PURPOSE:To provide a magnetic field generator for reducing influence of a leakage magnetic field inexpensively in a small size by supplying a current regarding an exciting current to a correction coil disposed around the generator. CONSTITUTION:An exciting current to be supplied from an exciting power source 4 to an exciting coil 3 is reduced by a variable attenuator 6 to be supplied to a correcting coil 5.

When the area of the coil 5 is S, the number of turns is n and the current is i, the generated moment Mc is represented by Mc=mu0 Sni. The moment is a vector amount. If the coil 5 is so wound that the positions and directions of the M0 and the Mc are approximately coincident, a magnetic field for generating magnetic dipoles of M=M0+Mc is generated sufficiently remotely, and if the S, n, i are so decided as to be M =-M0, a magnetic field in which the M0 and the Mc are synthesized is sufficiently smaller than the M0 sufficiently remotely.

Abstract: PURPOSE:To prevent corrosion in a boiler so as to aim at improvement in power efficiency of a steam turbine by making a steam flow passage from the steam turbine branch into two branch lines and introducing one to a absorbing type condenser and the other to the boiler via a condenser. CONSTITUTION:Steam which passes through a boiler 1 and a superheater 2 drives a steam turbine 3, then it is made to branch into branch lines 55, 56. Steam which passes through the branch line 55 is introduced to an absorbing type condenser 4 and absorbed by absorbent solution from a line 21. Meanwhile, steam which passes through the branch line 56 is returned to the boiler 1 via a regenerator 50 and a condenser 51. On the other hand, the absorbent solution which absorbs steam passes through a heat exchanger 5 and is heated in the regenerator 50. Steam which is generated by boiling is fed to the condenser 51, while the condensed absorbent solution is fed via the heat exchanger 5 to an absorbing type condenser 4 so as to be sprinkled therein. Thereby corrosion in the boiler can be prevented, so that steam pressure which is generated in the boiler can be set high. And steam pressure at a steam turbine outlet can be set low, so that improvement in power efficiency of the steam turbine is made possible.
