Title: Semiconductor-laser driver circuit
Inventor: DATE KOICHI
IPC: H01S5/042
Filed: 1992-12-25
Abstract: PURPOSE:To provide a semiconductor-laser driver circuit, in which a noise level is reduced. CONSTITUTION:In a semiconductor-laser driver circuit light-emitting and driving a semiconductor laser by a driving signal, in which a high--frequency signal A1 is overlapped to an input signal, said high-frequency signal A1 is formed in a rectangular wave signal, and optical output power B1 can be formed in a rectangular wave shape by overlapping the high-frequency rectangular wave signal Al to the input signal, thus making the peak value of the optical output power B1 lower (l//2Pmax) than that (Pmax) at the time of a sine wave shape. Consequently, allowance up to the rated power limit Pmax of the semiconductor laser is extended so much, and the high-frequency level of the high-frequency signal can be made larger than that at the time of the sine wave shape. Accordingly, the spot diameter of laser beams is reduced, and a noise level can be made lower than that at the time of the sine wave shape. Allowance up to rated power is extended, thus allowing the overlapping of the high-frequency signal even at the time of lighting and at the time of erasing.

Title: Method of informing run-out battery of portable instrument
Inventor: INOSE FUMIYUKI
IPC: G04G99/00
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To give an alarm that the battery has run out in consideration of the use condition, not only the data on the remaining capacity of the battery in a portable instrument. SOLUTION: The necessary alarm is that the battery run out, for example, in a day, while such as alarm has little effect to inform the remaining capacity of the battery is 10%. Further, as for a primary battery, giving the alarm in the situation that no primary battery can be obtained, or as for a secondary battery, giving the alarm in the situation that the battery cannot be charged is meaningless; but instead, the timing for giving the alarm should be considered. Therefore, by storing a model of power consumption of the instrument in the instrument and always grasping the current capacity of the battery, the time when the battery runs out is estimated, and if necessary, the alarm is given when the instrument is used under the similar situation.

Title: Prism squareness-measuring method
Inventor: INOUE HIROYUKI
IPC: G01M11/00
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method which can simply and presisely measure squareness and profile irregularity of a rectangular prism irrespective of the form other than the two rectangular faces. SOLUTION: The part of a prism 14 except two rectangular faces 2', 3', to be measured is dipped in a matching liquid 15. With respect to the direction of a laser light 11 of a laser phase measurement interferometer 4, the two rectangular faces 2', 3' to be measured are set as 45 deg., and the surface 17 of matching liquid 15 is set to be perpendicular. Since the part of the prism 14 other than the two rectangular faces 2', 3' is dipped in the matching liquid 15 having the same refractive index as the prism 14, the form of a prism face 13 on the side which the laser light 11 of the interferometer 4 enters is canceled by the matching liquid 15. Thereby squareness and profile irregularity of the two rectangular face 2', 2' to be meaured can be estimated.
