Title: Control system for compaction of roadbed
Inventor: SUZUKI TAKEO
IPC: E02D3/02
Filed: 1986-10-20
Abstract: PURPOSE:To speed up construction work and raise the accuracy of the construction work by a method in which the penetration amount of metal bars under a fixed condition at an adequate number of places is measured, electric resistance values are measured by using the metal bars as electrodes, and these values are compared with allowable values. CONSTITUTION:A copper bar with an about 30 deg. pointed tip, having a diameter of about 1cm and a length of about 20cm, is driven by a 2.5kg rammer for example into a specimen or field roadbed to measure the amount of penetration. Two copper bars as electrodes are then driven to a depth of about 7cm at an interval of about 10cm to measure electric resistance value between both the electrodes. Water content ratio is obtained from the electric resistance value and dry density is obtained from the penetration amount. These values are compared with a testing curve of the same soil quality as field which is obtained in laboratory in advance. If actually measured values of the field are within a given range, they are judged to be eligible. Quick and highly accurate measurements can thus be made and the construction work can be smoothly performed.

Title: Catalyst for ozone decomposition
Inventor: TERADA ISAO
IPC: B01J35/06
Filed: 1989-09-28
Abstract: PURPOSE:To obtain a catalyst which decomposes ozone in air even at a low temperature close to room temperature by using Ni (III) oxide, Ni2O3, as the ozone decomposing catalyst. CONSTITUTION:A particle growth suppressing agent such as for colloidal silica, alumina, etc., is added to an aqueous solution of water-soluble nickel salt such as nickel nitrate, nickel carbonate, etc., so as to raise the specific surface area of the nickel salt to about 100-250m<2>/g. Then, the solution is dried and fired to give Ni (III) oxide, Ni2O3.

Abstract: PURPOSE:To unnecessitate high illuminance exposure by constituting an output end surface as a ring type shape to illuminate a ring type peripheral region of a reticle containing a reticle pattern, and equipping an optical fiber guiding the light from a light source lamp. CONSTITUTION:The light from a light source lamp 1 is converged by an elliptical converging mirror 2, reflected by a plane reflecting mirror 3, and enters an optical fiber 4. The light which has entered the optical fiber 4 is guided by the optical fiber 4, outputted from the output end surface, and illuminates a reticle 6. The light from a reticle pattern 61 of the illuminated reticle 6 is focused on a wafer W by an imagery lens 5, and the reticle pattern 61 is transferred in the resist on the wafer W. On the output side of the optical fiber 4, element lines are bundled in the form of a sheath so as to illuminate a ring type peripheral region 62 containing the reticle pattern 61, and the output end surface 41 has a ring type shape. Hence the light guided by the optical fiber 4 illuminates only the ring type peripheral part 62, so that useless light is not present.

The finish hot rolled sheet is coiled at the temp. in the preceding and succeeding end parts within <=10% of the entire length of the sheet maintained higher by >=50 deg.C and <200 deg.C than the temp. in the intermediate part and at >=700 deg.C average coiling temp. The sheet is thereafter held for 5 to 60 minutes and is cooled with water. The sheet is in succession subjected to >=2 passes of cold rolling including intermediate annealing then to decarburization annealing after an annealing and separating agent is applied thereon. The secondary recrystallization is sufficiently developed over the entire length of the coil even if the annealing for inhibitor precipitation is omitted. The grain oriented electrical steel having the excellent magnetic characteristics is thus inexpensively produced.

Title: Oscillatory gyroscope
Inventor: TOMIKAWA YOSHIRO
IPC: G01C19/5607
Filed: 1994-09-20
Abstract: PURPOSE: To enable an oscillatory gyroscope to detect angular velocities with high accuracy by improving the oscillating characteristic of the gyroscope. CONSTITUTION: A vibrator 10 is constituted by respectively sticking piezoelectric material layers B and B to the front and rear surfaces of a constant-modulus body A. A total of three elastic pieces 10a, 10b, and 10c are formed on the vibrator 10. Couple of forces by f1 and f2 are applied to the elastic piece 10b from an electrode layer and the piece 10b is driven so that the piece 10b can be oriented in +x direction at a certain point of time. When the piece 10b is oriented in +x direction, the pieces 10c and 10a are oscillatorily driven so that the pieces 10c and 10a are deformed in +x and -y directions, respectively. When the vibrator rotates, the pieces 10b and 10c vibrate and are oriented in +y direction and the piece 10a vibrates and is oriented in -y direction at a certain point of time. The vibrations are detected as a voltage generated by a piezoelectric effect and the angular velocity of the vibrator 10 is found. When the side edges 14b of the pieces 10b and 10c and the side edge 14a of a base section 10d are formed in a discontinuous state, highly accurate vibrations can be obtained, because no torsional stress is applied to the base section 10d even when the pieces 10a, 10b, and 10c vibrate.
