Title: Production of carbonaceous powder for electroviscous fluid
Inventor: NAGAYAMA KATSUHIRO
IPC: C10N20/06
Filed: 1992-05-27
Abstract: PURPOSE:To attain small initial viscosity by pulverizing a carbonaceous powder raw material by a jet pulverizer to enhance the sphericity of particles to apply the obtained carbonaceous particulate to electroviscous fluid. CONSTITUTION:The carbonaceous powder material (e.g. coal or petroleum tar, pitch and resin or the like) is heat-treated and pulverized to 0.5-40mum average particle diameter. In this case, the sphericity of the particle is heightened by using a particle collision type jet pulverizer, and the obtained carbonaceous particulate is used as a dielectric particle and is dispersed into an oily medium excellent in electrical insulation resistance to obtain the electroviscous fluid. At the time of applying voltage to the electroviscous fluid, the apparent viscosity of the fluid is rapidly and reversibly changed.

Filed: 1982-09-14
Abstract: PURPOSE:To improve the pressure recovering performance of a disc type MHD generator by forming diffuser vanes in a wedge shape, and constructing to radially equalize the width of diffuser space formed between the vanes. CONSTITUTION:A diffuser vane 14 is formed in a wedge shape. The end of the vane 14 has a half vertex smaller than 10 deg., a height W, a length L. A plurality of vanes 14 are disposed at an interval of alpha deg. in a circumferential direction at the downstream of a generating current path so that the direction of the length L is matched to the radial direction of the generator. In this case, the half vertex angle and the disposing angle alpha deg. of the end of the vane 14 are selected so that the width G of the diffuser space 15 formed between adjacent vanes becomes equal from the front end to the rear end of the vane. The work fluid of the supersonic load which is passed through the generating current path generates an oblique impact wave 12 when reaching the end of the vane 14, thereby improving the recovering performance of the pressure.

Title: Information recording method
Inventor: KURABAYASHI YUTAKA
IPC: G02F1/13
Filed: 1989-06-26
Abstract: PURPOSE:To allow many valued information recording and continuous gradation recording of a large dynamic range with easy heat control by continuously changing the refractive index of a high-polymer liquid crystal to continuously change the quantity of reflected light. CONSTITUTION:The high-polymer liquid crystal is formed as a recording layer 3 and the refractive index of the recording layer 3 is changed by which the multiple reflection state to recording and reproducing light is changed and the information is recorded in many values on the optical information recording medium capable of making recording and erasing. The multiple reflection state is changed and the quantity of the reflected light is changed by continuously changing the refractive index of the high- polymer liquid crystal. A method for changing the refractive index of the high-polymer liquid crystal of the recording layer includes the control of liquid crystallization by application of heat and is exemplified by heating with a laser beam. A semi- transmitting reflecting layer 2 is preferably present in order to efficiently induce the multiple reflections. The multiple reflection conditions can be satisfied by the combination of the recording layer 3 and a total reflecting layer 4 if the optical thickness of the recording layer 3 is properly adjusted when such layer does not exist. The continuous gradation of a large dynamic resin is executed in this way.

Title: Optical character reader
Inventor: NANBA HIROMI
IPC: G06V30/148
Filed: 1982-09-16
Abstract: PURPOSE:To process character information and image information securely through simple operation without requiring any special format by providing a character line detecting circuit and discriminating between the character information and image information on a document automatically. CONSTITUTION:A scanning part 1 makes a scan on the document and its scanning pattern is written in a line buffer 2 in sequence. The character line detecting circuit 4 decides on whether said scanning pattern is a character line or not on the basis of binary-coded line projection generated by a line projection generating circuit 3. When the pattern is judged to be the character line, the scanning pattern is supplied to a character recognizing circuit 5 for character recognition. When not, namely, when the pattern is judged to be image information, the scanning pattern is supplied to an image data generating circuit 6 to perform information processing. Thus, characters and image information which are mixed in the same document are discriminated from each other automatically to secure read processing.

Title: Reel stand drive unit for tape recorder
Inventor: KAMIMURA TETSUROU
IPC: H02K49/10
Filed: 1978-12-28
Abstract: PURPOSE: To enable to deliver the stable and smooth torque without being subjected to the effect of ambient environment and time aging, by delivering the rotary torque of pulley to the reel stand with magnetic force.  
     CONSTITUTION: When the pulley 2 is turned via the belt, the magnet 3 turns also, and the magnetic flux from the magnet 5 to the iron plate 6 changes and eddy current is caused to the iron plate 6. Thus, torque is exerted to the iron plate 6 with the eddy current and the magnetic flux from the magnet 5, and the reel stand 3 rotates with a speed more or less delayed to the rotary speed of the pulley 2. This delay is determined with the distance between the iron plate 6 and the magnet 5 and the magnet force of the magnet 5. Thus, since the torque delivery part is of non-contact type, stable torque delivery can be made without being subjected to the effect of environment and time aging.

Title: Display element
Inventor: KOBAYASHI HIDEKAZU
IPC: G02F1/1335
Filed: 1990-06-20
Abstract: PURPOSE:To obtain the display element which has a good contrast, is free from a hysteresis characteristic and has high reliability by using a thermoplastic high polymer for a carrier and using a reflection mode. CONSTITUTION:Transparent electrodes ITO 2 and transparent electrodes ITO 5 are formed on a substrate 1 and a substrate 6 and a mixture composed of a liquid crystal and the thermoplastic high polymer is inserted between these substrates. A reflecting plate 7 is disposed on the outer side of the element part formed in such a manner by inclining the plate 3 deg. with the surface of the element part. Since light passes twice the element in such a manner, the curve of the square of the electrooptical characteristics measured by a transmission mode is obtd. There are substantially no hyesteresis characteristics if the thermoplastic high polymer is used. Since the carrier is not formed by polymn., the liquid crystal is less damaged. The reliability is, therefore, improved.

Title: Linear guide mechanism for magnetic disc device
Inventor: YOSHIDA SHINOBU
IPC: G11B21/02
Filed: 1985-07-24
Abstract: PURPOSE:To make it difficult that the read/write error due to external oscillation and thermal deformation occurs, by specifying the arrangement of six rolling wheels, which support a carriage, and the direction of the force which supports the carriage and applying a prepressure to a proper position. CONSTITUTION:A guide arm 12 which supports a magnetic head 11 is coupled to a carriage 4, and a voice coil 14 is coupled to the carriage 4. Six rolling wheels 2 are arranged on side faces of the carriage 4 as supporting points, and five rolling wheels 2 have inner wheels fixed to the carriage 4, and one rolling wheel 2a is engaged with the carriage 4 through a flat spring 3, and positional relations between the carriage body and a rail 1 are determined by fixed rolling wheels 2. Since such supporting structure is constituted that the outward motion of the carriage 4 on the surface of a disc 13 is supported rigidly and the inclination around the (y) axis is difficult to occur and the supporting force acts outward with a plane parallel with the disc 13 as the boundary, the restorability for meandering motion is improved. Since the prepressure is applied to the center, the inclination around the (y) axis due to thermal deformation is small to make the occurrence of read/write error difficult.
