Title: Optical pickup device
Inventor: HONMA OSAMU
IPC: G11B7/135
Filed: 1991-04-05
Abstract: PURPOSE:To prevent the deterioration of a reproducing characteristic due to the change of temperature and to obtain a stable performance by making the change ratio of the focal distance of a collimater due to the temperature approximately coincident with the coefficient of thermal expansion of the supporting member of the collimator. CONSTITUTION:A collimator lens 3 consists of a Fresnel lens, the base of the collimator lens 3 is formed with the same material as that forming a supporting member 11 supporting a laser light source 1 and the collimator lens 3, and therefore, they have the same coefficient of thermal expansion. The change ratio of the focal distance due to the temperature of the Fresnel lens is equal to that of the base. Accordingly, even when the supporting member 11 expands or contracts due to the change of temperature to cause the change of the distance of the collimator lens 3 and the laser light source 1, the focal distance of the collimator lens is changed by the same degree. Thus, the laser light source 1 is always kept at the focal position of the collimator lens, parallel light 4 is always kept in complete parallelism, and the excellent reproduction characteristic can be realized against the change of temperature.

Title: Main rotor torque correcting device
Inventor: YAMAKAWA EIICHI
IPC: G05D1/08
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To stabilize fuselage attitude and improve control performance by adjusting an angle of attack to correct a vertical tail in which the angle of attack is variably supported and the reveres rotating torque of main rotor torque with a tail rotor. SOLUTION: When a main rotor 2 rotates, the fuselage 6 of a helicopter 1 receives main rotor torque T1 which rotates in the reverse direction to the rotating direction of the main rotor 2. A tail rotor 3 rotates at a prescribed pitch angle, generates thrust and generates torque T2 which rotates in the reverse direction to the torque T1. Vertical tails 4, 5 are supported at prescribed angles of attack, torque T3 which has the same direction as that of torque T2 is generated by changing an air flowing direction from the front of the helicopter 1. In the torque T1 to T3, T1+T2+T3+=0 is defined, and the fuselage attitude is stabilized. The angles of attack of the vertical tails 4, 5 and the pitch angle of the tail rotor 3 automatically correct torque of the main rotor 2 by the control of an actuator. Thus, a balancing state can be recovered and control performance can be improved.

Filed: 1988-03-28
Abstract: PURPOSE:To remove solids in a liquid efficiently and facilitate washing and removal of filtered solids as well by filtering liquids such as soil water utilizing clearances between laminated glass plates having rough surfaces. CONSTITUTION:When raw water is forced through a raw water feed port 2 into a vessel 1, the raw water is passed through the clearances between glass plates 4 and flows out from a treated water discharge port 3, whereby solids contained in the raw water are captured in the clearances. Consequently, if the surface roughness of the glass plates 4 is properly selected, solids having particle diameters not less than desired diameter can be removed from the raw water. When the clearances between the glass plates 4 have been clogged with a solids due to a long operation, pressing force imparted by a press means 5, which presses the glass plates 4 in a direction perpendicular to that of the laminated layers, is loosened and thereafter washing liquids are injected into the clearances from the treated water discharge port 3 to wash solids having adhered to the clearances.
