Title: Vibration control damper
Inventor: NOMICHI TOSHIYUKI
IPC: E04B1/18
Filed: 1989-11-17
Abstract: PURPOSE:To effectively absorb vibration energy acting on a structure by a method wherein plate-like plastic deformation members are connected to the structure and the members are made to generate either elastic or plastic deformation with axial force acted in the direction of axial center when the vibration is applied. CONSTITUTION:Braces 6 and 6 are provided between crossing points 5 and 5 of columns and beams of a structure 1 so that the braces are connected to the crossing points with connecting plates 8. A plurality of plastic deformation members 9 in plate shape are provided in layers to a crossing where the braces 6 and 6 cross each other. When vibration acts on the structure 1, relative vibration is produced between the upper beam 3 and the lower beam 3', making axial force act in the direction of axial center of the brace 6. While the vibration is still small, it is absorbed by elastic deformation of the plastic deformation members 9 and when the vibration becomes larger, the plastic deformation members 9 start to produce plastic deformation and the vibration energy is absorbed by the energy of the plastic deformation, restraining the structure 1 from being affected by the vibration. Thereby vibrations from small to large in scales can be effectively absorbed with a single type of vibration control damper.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To analyze an amino acid with high resolution without increasing a load pressure independently of a flow velocity, by using a column having a chemical modification by a silylating agent provided at a silica gel surface of a specific double pore structure.

Abstract: PURPOSE:To perform a clear print on rough paper by forming a communication hole communicating with a common electrode at a protective layer, and disposing set electrodes electrically connected to the common electrode through a conducting member formed in the hole on the protective layer. CONSTITUTION:A plurality of common electrodes 14 led from heat generating resistors 13 are connected to set electrodes 18 on a protective layer 16 through a conducting member 19 in a communication hole 17 at an arbitrary position on a board 11, and power is supplied through the electrodes 18.

Title: Electrode head for power supplying transfer recording
Inventor: KITA TATSUYA
IPC: B41M5/382
Filed: 1990-11-06
Abstract: PURPOSE:To eliminate concentration of current to ends of electrodes so as to prevent local heating, make applying energy large so as to obtain sufficient print density, and reduce abrasion of the ends of the electrodes by forming one sides of counter electrodes facing each other to which voltage is to be applied by a material having a volume resistibility larger than that of other sides separated from each other. CONSTITUTION:High resistance layers 11 are formed on one sides of an electrode head 10 facing each other. When a voltage is applied between electrode groups 10a and 10b, a current flows there through a resistance layer 1. However, as the high resistance layers 11 are arranged on the counter sides, the current flowing through ends of the electrodes on the counter sides decreases not concentrating in this part, so that the density distributions of the current flowing in the resistance layers are uniformed and local heating can be restrained. As a result, local heat load can be reduced so that an applying energy can be made to be large and print density can be raised. Since there is no local heating, abrasion of the electrodes will not occur easily. If the high resistance layers 11 are constituted in a way of multilayer and volume resistibility is made such that the closer to the counter sides, the larger the volume resistibility is, the density distributions of the current are further unified and the local heating can be prevented.
