Title: Objective lens of endoscope
Inventor: KONNO MITSUJIRO
IPC: G02B13/18
Filed: 1992-12-25
Abstract: PURPOSE:To eliminate chromatic aberrations, to decrease the number of lens elements and to reduce a cost by arranging a diffraction type optical element having a positive effect nearer the image side than a full-aperture diaphragm in a lens system. CONSTITUTION:The focal length of the diffraction type optical element of the objective lens of the endoscope applied to an extremely fine fiber scope to be mainly used for a blood vessel, etc., is about 10 times the focal length of ordinary lenses and, therefore, the overall length of the telecentric optical system in which the lens near the image plane is the diffraction type optical element increases too much. This objective lens is, thereupon, constituted, successively from the object side, the diffraction type optical element (provided on the image side surface of a parallel plane plate) having the diaphragm and the positive effect and the positive lens consisting of ordinary glass. The conditions of equation 1<fD/D<3 are satisfied when the focal length of the diffraction type optical element is defined as fD and the distance from the diaphragm to the optical element as D. The maintenance of the telecentric characteristic is difficult when the lower limit of the above-mentioned conditions is exceeded. The eclipse by the total reflection of the positive lens is of a problem when the upper limit is exceeded.

Title: Reflection plate, reflection type polarizing plate and reflection type liquid crystal display device
Inventor: HAYASHI SHIGETOSHI
IPC: G03B21/60
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain a bright and good visibility even though the device is viewed from the angle, in which the reflection of external light beams is avoided, by having the reflection plate display section of the device whose cross section has the shape of circular-arcs being connected together and setting the angle between a base line and the tangent of the circle at the point of intersection of the circular-arc and the base to be within a specific range. SOLUTION: The reflection plate has a reflection plate display section whose cross section has the shape of circular-arcs being connected together and the angle (an angle of elevation) between the base line and the tangent of the circle at the intersection of the circular-arc and the base line is set to be within the range of 2.5 to 20 degrees. The following method is used, for example, to form the shape of the substrate surface section of the reflection plate, i.e., negative types having the objective shapes are formed on a roll and the forms are made by a roll transfer method. The reflection plate is made by laminating on a polarizing plate with acrylic adhesive and the plate is made into a reflection type polarizing plate suitable for a reflection type liquid crystal display device.  By mounting such a reflection plate or a reflection type polarizing plate on a liquid crystal display device, the reflection type liquid crystal display device having a superior visibility is obtained.

Title: Hermetically-sealed container
Inventor: OSADA SHINICHI
IPC: B65D81/34
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent burst during heat cooking by a microwave oven, by imparting easy-to-release properties to a thermal adhesive part, also by forming a projection part so as to project in the direction of the inside of the hermetically-sealed container, and by forming a cutting blade or notch in it. SOLUTION: When a container 1 is subjected to heat cooking in a microwave oven, vapor generated from food and air in a package bag thermally expand, and consequently internal pressure F increases and the hermetically-sealed container 1 swells up. On the other hand, from the inside of the hermetically-sealed container 1, release due to layer-interspace release or cohesive failure caused by the internal pressure F starts to occur between the innermost layers or in the innermost layers of a substantially-semicircular projection part 3 formed almost in the middle of one side of the hermetically-sealed container 1.  Then, the hermetically-sealed container 1 allows the escape of the internal pressure F when the release caused in the substantially- semicircular projection part 3 almost in the middle of the one side of the hermetically- sealed container 1 reaches a notch 4, and thus preventing the hermetically-sealed container 1 itself from bursting. In addition to that, the foot stored in the hermetically- sealed container 1 can be allowed to settle by its own heat until the relapse caused in the projection part 3 reaches the notch 4.

Title: Obstacle detecting radar for, particularly, automobile
Inventor: ARTIS JEAN PAUL
IPC: G01S13/931
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To preserve the quality of phase measurement by measuring distances from the phase difference between received signals relevant to a continuously transmitted frequency by using a plurality of frequency having a specific relation among them. SOLUTION: Obstacle detecting radar relies upon sine wave transmission and reception performed at two pairs of frequencies of F1 and F2 and F3 and F4 and the frequencies have the relations expressed by formulae I and II among them. For the case of radar for automobile which is suitable to a range of about 150m, the transmitting frequency is changed in such a way that the frequency F3 is used for transmission after the frequency F1 is used and, thereafter, the frequencies F2 and F4 are successively used for transmission. After the frequencies are used, new transmission is stated by using the frequency F1 . The frequencies F1 , F2 , F3 , and F4 are respectively set at 76GHz, F1 +ΔF'(230kHz), F1 +ΔF(750kHz), and F2 +ΔF.  Then the distance from a target is measured from the phase differences between the received signals relevant to the frequencies F1 and F3 and between the received signals relevant to the frequencies F2 and F4 . Therefore, the quality of phase measurement which becomes important when the speed of the target in the radiating direction is nearly zero can be preserved.
