IPC: A61B3/13
Filed: 1989-02-07
Abstract: PURPOSE:To easily detect the glance of examinee with high accuracy by projecting a predetermined pattern on the eyeball of the examinee and again forming a pattern image on a light detecting surface using the luminous flux based on the scattering light from the eyeball. CONSTITUTION:The infrared rays of a light source 8 is projected on a diffusion plate 6 by a projection lens 7 and the pattern on the surface of a mask 5 is illuminated by the scattering light from said diffusion plate 6.

The infrared rays scattered and reflected by the eyeball are again formed into an image on an area sensor 10 through the dichroic mirror part 26a and a light detection lens 9. The pattern on the upper surface of the mask 5 is compared with the re-formed pattern image 13 on the surface of the area sensor 10 to detect the boundary point of the cornea and the sclera and the reference point of the cornea to a light detection means. Further, the optical axis of the eyeball is calculated from the coordinates of respective specific points and correction is applied to said optical axis to calculate the optic axis and point of fixation of the eyeball.

Title: Discharge lamp device
Inventor: WAKIMIZU YUKIO
IPC: H01J61/36
Filed: 1993-02-17
Abstract: PURPOSE:To make the whole body of the device compact and to improve the durability, by forming a thermal insulation layer between an arc tube engaging hole and an arc tube, as well as holding the arc tube by an insulating disk. CONSTITUTION:The front end of an arc tube 10 is supported by a single lead support 36, and the rear end 14 is supported by an arc tube engaging hole 24. A globe 50 for ultraviolet-ray shielding is fixed and held by a ceramic disk 30 fixed to an insulating base 21, and it surrounds the tube 10. While the tube 10 is held by the disk 30, the engaging hole 24 is formed larger than the rear end 14 of the tube 10, and thereby, a thermal insulation air layer is formed between the rear end 14 and the engaging hole wall. Consequently, only one lead support will do to support the arc tube 10, and the globe 50 for ultraviolet- ray shielding can be made compact. At the same time, the heat transmission between the arc tube 10 and the engaging hole 24 is blocked, and the durability of the insulating base is improved.

Title: Magnetic tape for attraction
Inventor: TAKEDA SHIGERU
IPC: H01F1/117
Filed: 1979-03-12
Abstract: PURPOSE:To obtain a powerful attracting force without deterioration thereof by sticking soft magnetic powder and permanent magnetic powder on flexible tape- shaped bodies and vertically magnetizing the surfaces to form multipoles. CONSTITUTION:Soft magnetic powder 2 and permanent magnetic powder 3 in which binders 4 and 4' is mixed are applied on flexible tapes 1. Then, the binder is cured, with the surfaces of said tapes A and B being vertically magnetized to form multipoles. Since the attracting forces of these tapes A and B are proportional to the amount of magnetization, the attracting forces become proportional to N<2> when both tapes are divided into N portions which are to be magnetized. Since the soft-powder layers 2 serve as a magnetic yoke locate at the back surfaces where the multipole magnetization is performed, the attracting forces are multiplied. As these tapes utilize the attracting forces of the magnets, the attracting forces of the tapes used for the attracting portions which are frequently loaded and unloaded are not deteriorated and are very effective.

Title: Nonaqueous secondary battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M10/05
Filed: 1990-02-09
Abstract: PURPOSE:To enhance the cycle characteristic of a nonaqueous secondary battery by using as the active material of a positive electrode a mixture of a fibered active material and grains of active material. CONSTITUTION:A fibrous active material and granular active material such as manganese dioxide, vanadium pentoxide and manganese oxides containing molybdenum trioxide are mixed together and used as the active material of a positive electrode 1. In such a structure the fibrous active material combines the granular active material to one another so that the strength of the positive electrode is increased. The collapse of the positive electrode 1 is restrained by the combining effect of the fibrous active material even when the volume of the active material of the positive electrode 1 expands and contracts due to the cycle of charge and discharge of a battery. Even when charge and discharge are repeated, the active material of the positive electrode 1 and a conductive agent are therefore kept in good contact with each other and so lowering of positive electrode capacity is restrained and the cycle characteristic of the battery is enhanced significantly.

Title: Ink jet recorder
Inventor: IZUMIZAKI MASAMI
IPC: B41J2/05
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the adhesion of foreign particles produced at the time of delivery, such as ink mist and paper dust, on a delivery port surface of a recording head by mounting air flaw generation means for generating an air flow between a recording head and a material to be recorded. CONSTITUTION:At the time of recording, an air blow fan (an air flow generation means) 7 is actuated to generate an air flow in the direction of an arrow T between a full-multihead 1 and a material to be recorded set on a feed belt 3. For example, an air flow is generated in the direction of the arrow T, i.e., in the sane direction as the feed direction of the recording material. In this manner, a relative humidity between the recording head (full-multihead) 1 and the recording material is lowered, whereby the dewing of mists and the adhesion of suspended mists are prevented. In addition, a suction fan 9 (the other air flow generation means) may be actuated at the same time. Only the suction fan 9 may be actuated as an alternative to actuating the air blow fan 7. In these methods, substantially the same operational effect can be obtained.
