Patent JP-H03109519-A (JP)
Title: Coupling optical device
Inventor: HAYASHI YUKIHIRO
IPC: A61B6/00
Filed: 1989-09-22
Abstract: PURPOSE:To prevent the decrease in a peripheral light quantity while shortening the length over the entire part by constituting the device of a half mirror, a concave mirror and a concave lens, thereby preventing the light reflected by the imaging plane of one image pickup device from being imaged by the other image pickup device to form a virtual image. CONSTITUTION:The incident collimated beams of light are reflected by and transmitted through the half mirror 5 and are divided to the reflected light and the transmitted light. The reflected light is introduced to one image pickup device 8. On the other hand, the transmitted light is reflected by the concave mirror 6 and is returned to the half mirror 5 while focusing. This light is reflected by the mirror and is directed toward the concave lens 7. The light is again returned to the collimated beams of light by this concave lens 7 and is made incident to the image pickup device 9. The light returned from the image pickup device 8 transmits the half mirror 5 at about 5 to 15% thereof and is made incident to the image pickup device 9 side. Since the concave lens 7 exists in this route, the light diffuses. The imaging of the light at the image pickup device 9 is eventually prevented. In addition, the decrease in the peripheral light quantity is prevented while the length over the entire part of the device including the primary lens for collimating the incident light is shortened.

Abstract: PURPOSE:To simplify the mounting of an automatic focusing mechanism by providing a linear image sensor for automatic focusing, on the same semiconductor chip as a linear image sensor for an image pickup. CONSTITUTION:A part of object light beams which has been made incident on a triangular half prism 20 through a photographic lens 10 is divided into the upper and the lower directions and passes through the inside of optical path bodies 22, 24, and enters the photodetecting surface of linear image sensors 16, 18. Subsequently, an optical path to a virtual photodetecting surface P being in the middle of height of the photodetecting surface of the sensors 16, 18 is selected so as to become equal optically to the image pickup optical path of a linear image sensor 12. Accordingly, the sensor 16 having a photodetecting surface 16a being higher than a photodetecting surface MP, and the sensor 18 having a photodetecting surface 18a being lower than the photodetecting surface MP are placed in a rear focus position, and a front focus position, respectively. Accordingly, automatic focusing is executed by moving the lens in the optical axis direction in accordance with the difference of output signals of the sensors 16, 18 in accordance with a contrast method.

Title: Lens with variable focal length
Inventor: KITAGISHI NOZOMI
IPC: G02B15/08
Filed: 1984-11-26
Abstract: PURPOSE:To obtain a variable focal length lens which has light performance, compact constitution, and a high power variation rate by providing at least one lens group with at least one distributed index lens which has the same optical axis with other lenses. CONSTITUTION:The A zoom lens consists of the zoom part composed of the 1st positive lens group 11 which is fixed during power variation from the object side, the 2nd negative lens 12 which moves in optical axis directions during the power variation, and the 3rd positive lens group 13 which correct moving focus movement in the optical axis directions during the power variation, and the relay part composed of the 4th positive lens group 14 which is fixed during the power variation. The 2nd negative lens group 12 of this zoom lens uses the distributed index lens with a refractive index distribution which increases in refractive index radially from the optical axis to the outer periphery. This distributed index lens consists of one element, but compensates aberration variation and is superior, specially, in the ability to correct the Petzval's sum and spherical aberration, so the overall length of the whole system is decreased by increasing the power of the zoom part or decreasing the telephoto ratio of the relay group.

Title: Tape recording/reproducing device and tape ejecting method
Inventor: SANO TAKANOBU
IPC: G11B15/665
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To extend the life of tape loading/unloading repetition. SOLUTION: When a tape is ejected in a device area DA as a tape ejecting area in at least one place of a tape recording medium, an ejecting position on the tape, i.e., a tape feeding amount X from a boundary position with a system area SYS is randomized. Specifically, the feeding amount X is calculated based on the number of tape loading and the integrated rotation time of a rotary drum. Thus, the ejecting of the tape in the same place is prevented, and the concentration of tape damaging in a particular place by tape loading/ unloading is prevented.

Title: Indoor air conditioning process having heat radiating source
Inventor: INOUE SHUNJI
IPC: F24F3/00
Filed: 1984-11-26
Abstract: PURPOSE:To enable a room temperature to be maintained at 40 deg.C or less without using a large cooling device in a condition in that the number of indoor ventilating times is held at minimum limit within a necessary range, by a method wherein a part of the air supplied is caused to flow to the interior of the hood of a radiating source to cool the radiating source, and the remaining air is sucked through an exhaust port to an exhaust duct to exhaust it to the outside of a room. CONSTITUTION:A part of the air fed in a chamber through a feed air duct 5 is caused to flow to the interior of a hood 9 from a lower opening 10 of the hood 9 to cool a heat radiating source, and thereafter the air is efficiently exhausted through an exhaust dust 12 to the outside of a chamber togetherwith a high temperature heat of which the interior of the hood 9 is full. Thereby, if the rest of the air fed in the chamber is sucked through an exhaust port 13, located away from a feed air duct, to the exhaust dust 12 to maintain the number of indoor ventilating times at about 4 times/Hr, it is easy to maintain a room temperature at 40 deg.C or less. This enables satisfaction of a necessary condition without a sharp decrease in the temperature of the air to the interior of a chamber with the aid of such a large cooling device as a conventional cooling device.
