Title: Magnetic disk device
Inventor: SHIBATA HARUO
IPC: G11B21/10
Filed: 1986-03-24
Abstract: PURPOSE:To avoid the generation of a thermal off-track by performing the control impressing a voltage in the direction contradicting the inclination of the shaft due to the thermal deflection on the piezoelectric member combined to the shaft of the arm member to which a magnetic head is fitted. CONSTITUTION:Positioning data (servo pattern) are written on one part of the face of the magnetic disk 4a at the uppermost part and one part of the face of the magnetic disk 4c at the lower most part at the room temp. time in advance. The magnetic head excepting the magnetic head 5c reading the positioning data causes a dislocation, when the shaft 6 is inclined by the generation of the thermal deflection. In this way when the positioning of each magnetic head is performed according to the positioning data read by the magnetic head 5c at the lowermost part generating a thermal deflection on each mechanism part, for instance in case of the magnetic head 5a at the uppermost part locating at the continuous line position as shown in the figure, the positioning data read by the magnetic head 5a is read by a voltage control circuit 12, the inclination of the shaft 6 is corrected by impressing a voltage on the piezoelectric member 11 so that the pattern becomes normal, as a result, the position of each magnetic head 5a is corrected.

Title: Recorder
Inventor: YANAGI HARUYUKI
IPC: B41J2/33
Filed: 1987-03-23
Abstract: PURPOSE:To obtain a transfer recording image having high image quality, by forming a recording material impregnated with ink from a plurality of porous layers with the diameter in a surface layer being shorter than that of an inner layer, thereby forming an ink image passing through the surface layer from micro ink dots. CONSTITUTION:A recording material 2 is rotated in the direction of an arrow (a) synchronously with the carriage of a recording paper 7 so as to send a recording image signal to a recording head 5 synchronously with the rotation. Consequently, a heating element 5b is heated corresponding to the signal so as to heat the surface of the recording material 2 at a contacting portion B selectively. Heat is transmitted from the outer layer 2b to the inner layer 2a of the recording material 2, and an in having reduced viscosity permeates through the outer layer 2b. Since the hole in the outer layer 2b has diameter smaller than that of the hole in the inner layer 2a, an ink image 22 composed of micro ink dots is formed on the outer layer 2b corresponding to the heating. The ink image 22 moves as the recording material 2 rotates and reaches a pressure contacting portion A where it is transferred onto a recording paper 7 which is carried synchronously and pressed thereto, thus performing a recording of a clear image onto the recording paper 7.

Title: Formation of pattern
Inventor: MORIMOTO AKIO
IPC: C23F1/00
Filed: 1984-04-02
Abstract: PURPOSE:To obtain a fine resist pattern smaller than 0.5mum in a two-layered resist structure, by forming the upper resist pattern into a trapezoid-shape. CONSTITUTION:An ultraviolet light resist is used as the upper resist and a far- ultraviolet light resist is used as the lower resist 12. An upper resist pattern 13 is used as a mask for forming a lower resist pattern 15. Since the resist has a refractive index larger than 1, light incident from the side faces of the pattern 13 is refracted to inside of the pattern 13. Accordingly, the intensity of light becomes larger near the central axis where the refracted rays concentrate. In such a manner, a fine pattern 15 divided into two portions can be obtained on the lower resist 12 when developed.

Title: Vapor adsorbent for molten carbonate fuel cell
Inventor: SAKURAI TOSHIHIDE
IPC: H01M8/04
Filed: 1993-03-25
Abstract: PURPOSE:To improve adsorption efficiency of corrosive vapor generated from an electrolyte by defining the ratio of the amount of silica as 5-40wt.% for an adsorbent consisting of particles of a mixture containing alumina and silica. CONSTITUTION:An adsorbent is formed of particles of a mixture containing alumina and silica, and the ratio of the amount of silica is defined as 5-40wt.%, while the particle diameter of each particle of the mixture is approximately 3-10mm. Although the absorbing rate of corrosive vapor by the alumina particle is relatively fast, when a certain amount of vapor is absorbed, the surface of the adsorbent reacted with the vapor is peeled off and is thus disintegrated. The absorbing rate of corrosive vapor by the silica particle, on the other hand, is slow, and an adhesive material is formed on the surface of the particle by adsorbing the vapor. When the ratio of silica is defined as 5-40wt.%, the absorbing rate is fast and no adhesive material is formed on the surface of the particle. When the particle diameter is defined as 3-10mm, the specific surface becomes appropriate, thus improving handling property and preventing absorbing efficiency. The adsorption efficiency of corrosive vapor formed from electrolyte can thus be improved.

Title: Vehicle information communication processing method
Inventor: SAKAMOTO HIROBUMI
IPC: H04W4/04
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce the effect of missing data resulting from a failed transmission onto a vehicle information communication system where sampled data for driving for a prescribed block are sent within a prescribed communication allocation time. SOLUTION: In the case that the transmission from a vehicle to a base station is failed, vehicle information that should have been transmitted for that time is interleaved by a half (step 9) and a sampling period is doubled up to a succeeding communication allocation time (step 10). Since the amount of the vehicle information sent next is compressed by the same amount as that for usual one transmission amount, the vehicle information that should have been transmitted is able to be sent within a succeeding communication allocation time. The status of the vehicle when the vehicle information is interleaved is not accurately grasped in comparison with the case that the information is not interleaved, but the status of the vehicle is far accurately grasped in comparison with the completely missing information.
