Title: Facsimile communication control system
Inventor: SAKASHITA TADAAKI
IPC: H04L29/08
Filed: 1985-11-29
Abstract: PURPOSE:To shorten the communication time by deciding the circuit speed when picture information on the next page is transmitted in response to the degree of a decoding error of the picture information on the present page transmitted and then transmitting the picture information on the next page with no MODEM training. CONSTITUTION:The circuit speed information set when the picture information on the next page is transmitted is put in an FIF field of a MCF of the reception message sent back from the receiver side against a post message EOM of the transmitting side together with the reception state information showing whether or not the picture information on the present page transmitted at this time is received normally or many errors are generated respectively. At the transmitter side the reception state of the picture information, i.e., the circuit state is grasped at that time point and the picture information on the next page is transmitted at a designated circuit speed with no MODEM training as long as said picture information on the present page is received normally. Thus the MODEM training is skipped without affecting the communication and the communication time is shortened effectively.

Title: Magnetic thin film memory
Inventor: OIKAWA KATSUYA
IPC: H01L21/8246
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a memory that a regenerative signal is hardly dispersed by fixing a shape of a magnetization reversible magnetic field region in a magnetic thin film with a magnetic field generated with at least two systems of conductive lines of a magnetic thin film memory provided with at least two systems of conductive lines regardless of a value of a recording bit. SOLUTION: Both pole current generation means 4 are arranged on both of a word line side and a figure line side, and directions of currents flowing through both of the word line and figure line are changed simultaneously, and deformation in the magnetization reversible magnetic field region is prevented. Even when the directions of the currents of both lines of the word line and figure line are changed simultaneously, the shape of the magnetization reversible magnetic field region isn't changed. Similarly, the shapes of the magnetization reversible magnetic field region when an upward figure line current, a leftward word line current are made to flow, or when a downward figure line current, a rightward word line current are made to flow aren't changed also. Thus, the region recorded on a cell is fixed regardless of an information bit.  The both pole current generation means 4 is made one, and its output is connected to both of word line buses 9a, 9b and figure line buses 10a, 10b to simplify a circuit.

Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To realize high sensitivity measurement of glass transition point for polymer by applying a voltage to a sample in order to increase the temperature thereof, irradiating the sample with light and observing a second harmonic emitted from the sample. SOLUTION: An electric field is applied from a DC power supply 8 to a sample 7 which is then irradiated with a pulse light emitted from a titanium sapphire laser 1. Basic wave of the light is reflected on two dichroic mirrors 10 to pass the second harmonic. The second harmonic is condensed through a lens 11 onto a slit of a monochromator 12 and only the second harmonic is detected by means of a photomultiplier 13. The laser light is modulated by means of an optical chopper 9 and the second harmonic is detected using a lock-in amplifier based on the modulation frequency. While increasing the temperature of sample 7 in an electric furnace 6, intensity of the second harmonic is monitored and the relationship between the temperature and the intensity of second harmonic is studied.  The results are plotted and the glass transition point is determined based on the temperature dependency of intensity.

Title: Medium identification device
Inventor: RICHIYAADO PII SHINDORII
IPC: G07C9/00
Filed: 1992-09-11
Abstract: PURPOSE: To reduce effect on a near person or an environment by controlling a specific identification signal corresponding to a high frequency transmitted inquiry by a computer integrated in A part of a device. CONSTITUTION: When a medium is present in identification stations 15 and 16, a high frequency (r. f.) sensor 32 judges that contactless sensors 34 and 35 report the existence of 'truth', that is, the medium, decides whether or not a one-time flag is already set, and when the one-time flag is not set yet, the (r. f.) sensor 32 excites an antenna 33 of the identification stations 15 and 16, and generates the (r. f.) transmitted inquiry of a close tag. When the (r. f.) transmitted inquiry is received by the tag on the medium, the transponder of the tag temporarily generates an identification signal, and this signal is received by the antenna 33 and the (r. f.) sensor 32. Then, the (r. f.) sensor 32 decides whether or not the identification indicator of the tag is exactly read.

Title: Magnetoresistive element and manufacture therefor
Inventor: MOTOMIYA KAZUOKI
IPC: H01L43/12
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent magnetic effect from lowering by depositing a thin mag netic film having reluctance effect on a substrate and covering the thin magnetic film with an amorphous fluorocarbon film. SOLUTION: SiO2 is deposited previously on the surface of a silicon substrate 1 by thermal oxidation. NiFe, Au and Cr are then deposited sequentially by sputtering in same vacuum to form a thin film 2 of ferromagnetic metal. The thin metal film of three layers is then subjected to photolithography and etching to form a pattern of magnetoresistice element. After forming the thin film 2 of ferromagnetic metal, an amorphous fluorocarbon film (a-C: F film) 3 is formed as a protective film by RF ion plating. Since RF ion plating for forming a film while sustaining the substrate temperature at the room temperature can be employed when an amorphous fluorocarbon film is employed as a protective film, magnetic effect can be prevented from lowering.

Title: Interferometer
Inventor: ONO MASAHIRO
IPC: G01M11/02
Filed: 1989-10-16
Abstract: PURPOSE:To observe interference fringes in a broad range clearly even if luminous flux having whatever higher intensity distribution is used and to measure wavefront aberration and the like accurately by providing a light reducing filter wherein variable- density parts for reducing the light in proportion to the intensity distribution of the luminous flux are formed. CONSTITUTION:Laser luminous flux passes through a 1/4-wavelength plate and a 1/2-wavelength plate 102 and 103. The luminous flux is split into two luminous fluxes through a beam splitter 105. The laser luminous fluxes are rotated by approximately 180 degrees with image rotators 106 and 107, reflected from rectangular prism 108 and 109, overlapped and made to interfere. The laser luminous flux is guided on a image sensing surface 112 through a reflecting mirror 110 and an image forming lens 111. The interference fringes are observed with a monitor in real time. The intense part (central part) of the laser luminous flux is made to hit the dense part of a light reducing filter 118, and the intensity is weakened. The weak intensity part (peripheral part) is transmitted through the light part of the filter, and the intensity reduction is small. Therefore, the intensity distribution of the laser luminous flux at the image sensing surface 112 is not governed with Gaussian distribution. The intensity distribution of the interference-fringe part has a sine-curve pattern. The linear interference fringes are uniformly observed on the entire screen.

Abstract: PURPOSE:To enable the correction of mis-convergence dispersion due to the combination of a color picture tube and a deflecting yoke by fitting variable resistances in parallel to coils in a coma free deflecting yoke. CONSTITUTION:An E-shape magnetic material is so placed as to oppose a horizontal direction and auxiliary coils 2, 2' and 3 are wound around the center part of the E-shape magnetic material and both ends thereof. The auxiliary coils 2, 2' and 3 are connected in series to a vertical coil 1 so as to generate a 6-pole magnetic force line when an image plane is deflected upward. A variable resistance 6 is connected in parallel to the lower auxiliary coil 2', and another variable resistance 7 is connected in parallel to the auxiliary coils 2, 2 ' and 3. Also, another variable resistance 5 may be connected in parallel to the upper auxiliary coil 2. If a mis-convergence pattern occurs on the image plane, a current flow to the vertical auxiliary coil 2' is reduced and the force 4' of the magnetic force line due to the auxiliary coils 2, 2' and 3 is reduced respectively by increasing the resistance values of the variable resistances. As a result, vertical line cross mis-convergence is corrected.
