Inventor: SUZUKI TATSURO
IPC: G02F1/33
Filed: 1985-04-26
Abstract: PURPOSE:To form a practically sufficient scanning range and to display an object image on a TV monitor at a real time by forming acoustic/optical polarizing elements. CONSTITUTION:The polarizing surface ab of the 1st acoustic/optical polarizing element 3 is set up on the front focus F1 of a pre-group lens 4 of a relay lens 6. The back focus of the pre-group lens 4 coincides with the front focus of the post group lens 5. On the other hand, the polarizing surface cd of the 2nd acoustic/optical polarizing element 7 is set up on the back focus F2 of the post group lens 5. Consequently, the polarizing surfaces ab, cd are set up on optically conjugate positions respectively and made optically equivalent. Thus, troubles such as the shift of a polarizing point on the 2nd polarizing surface from the optical axis which is generated due to the shift of two polarizing surfaces in the optical axis direction which inevitably exists when two acoustic/optical polarizing elements are tightly arranged are removed and two acoustic/optical polarizing elements 3, 7 can be used under the most optically preferably condition.

Title: Descent traveling control device for vehicle
Inventor: HORIGUCHI MASANOBU
IPC: F16H61/02
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To improve a descent traveling performance for a vehicle having an automatic transmission mounted therein. SOLUTION: A traveling resistance is detected (S1 to S7) and a presence or an absence of a request for shift-down is detected in response to the detected traveling resistance (S8). Then, even in the case the the request for shift-down is present, a shift-down operation is executed (S12) only when an intention of a driver to decrease speed is detected (S9 to S11) and a driver's request for reducing speed is present. With such an arrangement as above, since a down-shift control to which the driver's request for reducing speed is reflected can be carried out, it is possible to further improve a descent traveling performance.

CONSTITUTION:When sleep operation is started at the time t1, the outputs B and C go to H to keep the output D at H. An audible sound is generated from a sound generation circuit 22 to enable the operation B at a sound volume specifying circuit 54. Under such a condition, when the user is awake, only betawave is detected 60 from a signal from a brain wave detector section 56, the output G1 moves to H while the sound volume specifying signal H1 to H to turn ON an analog switch 46 so that the audible sound will be generated at a large volume to promote the sleeping of the user. At the time t6, as the set time is reached, an alarm start signal is outputted to the output A and an audible sound is generated from the circuit 22. Under such a condition, when the user is in sleep, theta wave is detected 64 ad the output G3 moves to H while the signal H1 to H. Thus, a switch 46 is turned ON and the audible sound is generated at a large volume to prompt the awakening of the user.

Abstract: PROBLEM TO BE SOLVED: To obtain a uniform control characteristic in a wide range of operation by constituting a DC controller so that it may receive square values of a DC controlled amount and DC command value and forming a control loop so that the square value of the controlled amount may agree with that of the DC command value. SOLUTION: In a DC controller 31', a controlled amount square value calculator 313' receives a controlled amount V which is the output of a converter section 2 and calculates the square value of the controlled amount V and then outputs the result to a comparison subtracter 311' and a command value square value calculator 314' calculates a square value of a command value V* and then outputs the result to the comparison subtracter 311'. In order to make the controlled value V agree with the command value V*, a deviation e' is obtained from the comparison of the square values of V and V* by the comparison subtracter 311' and the deviation e' is amplified by a DC amplifier 312' and then the obtained AC command value ACT' is output to an AC control loop.  Furthermore, a value to correspond to the consumption power of a load is added to the output of the DC square value deviation amplifier and then the calculation result is output as an AC command value for an AC controller 32.

Title: Hologram lens
Inventor: YAMAZAKI TAKESHI
IPC: G11B7/135
Filed: 1989-04-12
Abstract: PURPOSE:To obtain the hologram lens which is small in the quantity to violate sine conditions even at high NA and has an excellent offaxial performance by curving the hologram lens in such a manner that the lens face thereof is displaced in the same direction as the lens face parts from the optical axis. CONSTITUTION:The hologram lens has the advantage that a lens having the high NA can be realized without aberrations. This lens has also the advantage that since the lens can be constituted of a single plate the reduction in weight of the optical system is possible. However, the conventional flat plate hologram lens has the problem in that the quantity to violate the sine conditions increases and the offaxial performance is degraded if the NA is increased. The hologram lens 11 is, thereupon, curved to displace the lens face in the same direction as the lens face parts from the optical axis. The displacement quantity of the hologram lens 11 is thereby increased with an increase in the height of incident rays in both cases of the infinity and finite of the object point, by which the quantity to violate the sine conditions is decreased.
