Title: Mechanical pencil
Inventor: KOBAYASHI SEIICHI
IPC: B43K19/02
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a mechanical pencil which can avoid a trouble in which built-in leads are scattered by pulling out a case for the refills under a condition that the chuck side is downward by mistake and prevents colored leads for the mechanical pencil from being broken when the colored leads are supplemented and easily performs discrimination of the colors of the leads and erasing and exhibits excellent displaying properties. SOLUTION: In a knock type mechanical pencil in which the front part of a case body of the case for the refills is removably bonded with a shaft joint provided on the back end of the chuck. the case for the refills is inserted into a cylindrical part 11 of the shaft joint 8 from the back end of the shaft cylinder 1 under a condition that the chuck 5 side faces upward and an elastic piece 11s is deformed outward and a projected part 11b is fitted into the channel part 16a of the case body 16 and the case for the refills is easily removably hooked to the shaft joint 8, and when the chuck side is made downward under that condition,  the cylindrical body 12 is slidably moved by its own weight on the outer peripheral part on which the elastic piece 11a and the projected part 11b are positioned and deformation of the elastic piece is avoided to make it possible to strongly fix the case for the refills to the shaft joint 8.

Title: Method and device for compensating active temperature numerical value of etalon in wavelength stabilization laser
Inventor: BROUTIN SCOTT L
IPC: H01S5/00
Filed: 2000-07-13
Abstract: PROBLEM TO BE SOLVED: To stabilize and lock absolute wavelength of laser beams by a method, wherein a temperature change of an etalon optical filter is compensated actively. SOLUTION: A temperature of an etalon filter 30 is monitored by a thermistor 32, and a controller 40 monitors the etalon 30 and a laser chip 12 by use of an etalon path signal, reference path signal and a temperature measured by the thermistor 32. Thus, a temperature of the etalon is monitored, and a value of grid-offset is adjusted, based on a temperature change of the etalon. Here, the laser system 10 uses a value obtained in the grid-offset in calculation of a difference for use in controlling a TEC 52, and can compensate effectively a change of etalon reaction generated from the temperature change of the etalon. By compensating for the temperature change of the etalon, the laser system 10 can lock effectively to the absolute wavelength of a laser beam.

Title: Negative electrode material for lithium secondary battery, method of preparing the same, and battery using the same
Inventor: ITO YOSHINORI
IPC: H01M10/05
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a negative electrode for a lithium secondary battery, having less deterioration due to repetitive charge/discharge and high charge/ discharge capacity and high energy density. SOLUTION: The negative electrode material for the lithium secondary battery contains a tin oxide having meso-pores of uniform diameter and shape. With the arrangement of the meso-pores, the specific surface area is larger and lithium ions are smoothly stored and released. With the diameter of the pores being smaller and having narrow and uniform distribution, the tin oxide can be filled in the negative electrode with a high density. With the pores being regularly arranged and uniformly shaped, the thickness of a tin oxide layer is controlled to be constant and the uniform and easy diffusion of lithium in the tin oxide layer is ensured.

Title: Optical recording medium and optical information recording/reproducing device
Inventor: MISAWA SHIGEYOSHI
IPC: G11B7/24062
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium on which more advantageous higher- density recording/reproducing can be performed by making the light-condensed spot minute. SOLUTION: The converged light 2 from a light source is condensed on an optical recording layer 6 through a first refractive index optical Kerr medium layer 4, having a low refractive index and the second refractive index optical Kerr medium layer 5 having high absorptivity. A thicker film can be used as the layer 4, since the absorptivity of the light 2 is small in the layer 4. The beam diameter of the light 2 can be made small due to self-converging effect, since the center part of the layer 4 has slightly higher intensity in the intensity distribution of the light 2 and consequently has higher refractive index than that of the peripheral part.  The beam diameter of the light 2 can be made smaller further by the self-converging effect, since the non- linear optical constant of the layer 5 is large even thought the film thickness is small Generally, materials having high absorptivity has a high refractive index. Therefore, in this case, since the wavelength of the light 2 when passing through the layer 5 becomes still further shorter, the diffraction limit, which is fixed by the wavelength and the converging angle of the layer 5, becomes smaller so that the beam diameter of the light 2 can be made further smaller.
