Abstract: PROBLEM TO BE SOLVED: To measure accurately an astigmatic angle by providing a gyro in a hand-held measurement section and obtaining an astigmatic axis angle using the signal of the gyro in an optometer to measure an astigmatic axis angle. SOLUTION: An optical system 2 and a light splitting member 3 are arranged from an examined eye E side on the lens axis 01 of a measurement section 1, an anterior segment imaging means 4 is arranged in the direction of reflection of the light splitting member 3 and a measuring system 5 is arranged in the direction of transmission of the light splitting member 3. In addition, an anterior segment display monitor section 6 is mounted on an examiner side, and the imaging means 4 is connected to the anterior segment display monitor 6. In such a measurement section 1, a small gyro 8 and an operation means 9 are provided.  The angle of the measurement section 1 when placed on a base 7 is used as a reference of measurement, the angle in the face vertical to the measurement lens axis 01 when the measurement section 1 is held by the hand is measured with the gyro 8 for the detection of the astigmatic angle. As the gyro 8 can measure each speed, an angle can be obtained by time integration of the value by an operation means 9.

Title: Manufacture of rco5 rare-earth cobalt magnet
Inventor: YONEYAMA TETSUTO
IPC: H01F1/08
Filed: 1986-05-01
Abstract: PURPOSE:To facilitate the processing by using a medium of water and to improve the magnetic characteristics by pulverizing RCo5 rare-earth cobalt permanent magnet alloy within water, drying the fine powder thus obtained and making a permanent magnet from it. CONSTITUTION:RCo5 rare-earth cobalt permanent magnet alloy is pulverized with a medium of water. The fine powder thus obtained is uniformly oxidized by the pulverization. The fine powder, after dried, is processed by an ordinary method to produce a permanent magnet. Since water instead of toluene is used as the medium for pulverization, the pulverization can be carried out more easily while the surface of alloy powder is oxidized and the magnetic characteristics can be improved.

Title: Copying machine
Inventor: KOYAMA HAJIME
IPC: G03G21/00
Filed: 1979-08-04
Abstract: PURPOSE:To make cleaning effect higher by providing two cleaning means, a conductive elastic material roller contacting an electrostatic image carrying body under pressure and an elastic cleaning blade disposed behind the same and providing a destaticizing function to the cleaning means.

Title: Radiograph
Inventor: YAMAMOTO TOSHIYOSHI
IPC: G01T1/20
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To facilitate image processing at an overlapped part by controlling the external shape and position of an X-ray detection means so that the external shape of the X-ray detection means is set within an overlapped range without exceeding the effective image pickup range of each image detection means. SOLUTION: A sensor unit 4 comprises an image detection means 1, an X-ray detection means 2, and a substrate 3. The X-ray detection means 2 is placed in the effective image range of the image detection means 1, thus minimizing loss until X rays reach a lower-side sensor unit 4, and allowing the luminance of the overlapped part of the sensor unit 4 to approach that of other parts, when the external shape and position of the X-ray detection means 2 are controlled so that they do not exceed the effective image pickup range of the upper-side image detection means 1. Furthermore, the image detection means 1 is composed of an Si-based material with a high X-ray transmittance, thus reducing obstacle shading being appearing in an image, and at the same time by uniformly suppressing the reduction of the luminance.

Title: Fm-am broadcast receiver
Inventor: KUMAGAI MORIO
IPC: H04B1/16
Filed: 1978-08-16
Abstract: PURPOSE:To simplify circuit constitution by eliminating the need for an AM quadrature detection circuit for obtaining a S curve signal, by making use of a quandrature detection circuit as a FM detection circuit even in AM broadcast reception. CONSTITUTION:In FM broadcast receltion, coil 22 is shorted via change-over switch 25 and phase shifter 17 serves appropriately as a FM phase shifter composed to coil 21 of FM quadrature detection circuit 16 and tuning circuit 23, so that an FM detection output and S curve signal output will appear at output terminal OUT. In AM broadcast reception, the shout of coil 22 is released by switch 25 and since inductance L21 of coil 21 is less than L22 of coil 22, the application of L21 and L22 causes no problem; since tuning circuit 23 can be ignored in terms of AM intermediate frequency, coils 21 and 22 and circuit 24 operate as phase shifter 17 of quadrature detection circuit 16, thereby obtaining a S curve signal of AM at output terminal OUT.

Abstract: PURPOSE:To provide only the person desirous of having information with the information and to reduce the cost of an information acquiring means for obtaining such information by operating a voice generating section by a driving signal from a driving section when a software magnetic material passes a magnetic field region. CONSTITUTION:A road side device 1 consists of an AC current generating section 2, a coil 3 for generating a magnetic field of a specified range by an AC signal, a driving section 7 which outputs a driving signal by a change in the magnetic field when the software magnetic material carried by a person enters the magnetic field region, a voice information section 9 which is operated by the driving signal from the driving section 7 and a voice generating section 11. The magnetic field is changed by the software magnetic material disposed within a stick when the sight handicapped person approaches a crossing or pedestrians' crossing, etc., and passes the magnetic field region. The driving section 7 outputs the driving section by such change in the magnetic field. The driving signal from the driving section 7 turns on the voice information section 9 and the information from the voice information section 9 is outputted as voices from the voice generating section 11. The person is thus able to obtain the desired information.

Title: Vertical magnetic head
Inventor: MURATA SATSUKI
IPC: G11B5/23
Filed: 1985-05-09
Abstract: PURPOSE:To obtain a vertical magnetic head having high recording efficiency and high reproducing efficiency by specifying the gap formed between a main magnetic pole and an auxiliary yoke set at a counter part against a magnetic recording medium. CONSTITUTION:A gap (artificial gap) (a) between a main magnetic pole 2 and an auxiliary yoke 1a set at the counter part against a magnetic recording medi um 5 is set at 150mum in this example (usually in a range of 70-250mum). Then a nonconductive magnetic material liek glass, etc. is molded into the gap (a). The magnetic flux which does not pass through the medium 5 and leaks out is increased between the pole 2 and the yoke 1a when the gap (a) is less than 70m. Then the vertical magnetic field intensity is reduced. While the magnetic flux induced up to the yoke 1a is reduced at a place right under the pole 2 when the gap (a) is larger than 250mum. The magnetic field intensity is increased at a place right under the pole 5 when the gap (a) is kept within a 70-250mum range and then becomes maximum in a 100-200mum. This secures high recording/ reproducing efficiency.

Abstract: PURPOSE:To provide a multilayer polymer alloy sheet for high moistureproof medicine packaging which has eminently balanced properties and a good appearance and moldability in processing by laminating polymer alloy layers in which the outer and inner layers have a higher compounding ratio of high density polyethylene than the intermediate layer. CONSTITUTION:In a multilayer polymer alloy sheet for high moistureproof medicine packaging, the outer, intermediate, and inner layers are made of a polymer alloy in which amorphous polyolefin with a heat distortion temperature of 100 deg.C or less and high density polyethylene are compounded. The outer and inner layers have a higher compounding ratio of high density olyethylene than the intermediate layer, and the three layers are laminated. The refractive indices of the outer and inner layers are the same; the refractive index of the intermediate layer is close to those of the outer and inner layers. Since two types of polyolefin are combined, the polymers of three layers have good compatibility. The laminated sheet has a good balance in properties such as processability, rigidity, scratch resistance, impact resistance, moisture proof, transparency, oil resistance, and chemical resistance.
