Title: Surface light emitting element
Inventor: NUMAI TAKAAKI
IPC: H01S5/10
Filed: 1993-06-08
Abstract: PURPOSE:To provide a surface light emitting element that fitting to two-dimensional integration with low power consumption by covering a side surface including at least an active layer with a reflecting mirror constituted of a multilayerd film and coating the reflecting mirror with a metal reflecting mirror. CONSTITUTION:As the side surface of a laser resonator is coated with multilayered reflecting films 20 and 21, and a metal reflecting film 31, spontaneous emission light is not emitted outside the laser resonator but remains in it. As its result, the natural emitting light is absorbed again by the active layer and carriers are regenerated. In ordinary laser resonators, a part of the carriers are lost outside a resonator and consumed being converted to the spontaneous emission light. The carriers being converted to the spontaneous emission light are again converted to the carriers and a carrier density in the resonator is practically heightened and a threshold value of laser oscillation lowered. As the threshold current of the oscillation is lowered, driving current is lowered and low power consumption is realized.

Title: Tape tension applying device
Inventor: TAKEDA SHUZO
IPC: G11B15/43
Filed: 1989-05-30
Abstract: PURPOSE:To make a tape tension applying device small in size and light in weight by simple configuration with the reduced number of parts and to enable stable traveling by applying load with the protruding part of an arm in contact with a fourth rotary body and setting the clutch force of the fourth rotary body larger than the clutch force of a second rotary body when a tape is rewound and reproduced. CONSTITUTION:A protruding part 18' is engaged with a fourth gear 111 by the turn of an arm 18 and the fourth gear 111 can not be rotated. Since the tape is moved in a rewinding direction, a take-up reel 51 is rotated and a fourth clutch gear 25 to be engaged with this reel 51 is also rotated. At such a time, the clutch load to be generated by a fourth clutch spring 27 and a fourth clutch felt 23 is applied to the fourth clutch gear 25 and tension can be applied to the tape. Then, by setting this clutch force, the suitable tension can be applied to the tape and the smooth travel of the tape can be realized. Thus, the clutch force of the fourth gear part 111 is set larger than the clutch force of a second gear part 110. Thus, a space is reduced without increasing the number of the parts and the stable travel of the tape can be executed.

At the detecting of the loading of the medium 10, a detection means 9 informs a writing means 12 of the detection. A file name changing means 11 changes the file name of image data, so that the file name is not duplicated to the file name of already recorded data. When the file name is changed, the means 12 writes the image data provided with the new file name obtained by the means 11 in a prescribed area of the medium 10. When the same image data are repeatedly copied in plural recording media, a repeating means 13 allows respective means 8, 9, 11, 12 to repeatedly execute the same processing.

Title: Mouse cursor setting system for optical mouse
Inventor: OZAKI MIDORI
IPC: G06F3/039
Filed: 1993-06-08
Abstract: PURPOSE:To provide a function for moving a mouse cursor to a corresponding point on a display at the time of clicking an optical mouse at an optional point on a reflection board. CONSTITUTION:A grid-like scale lines with unequal intervals to be gradually changed in the X and Y axis directions are plotted on the reflection board. When click operation specified by the optical mouse 4 is executed, a position on the board 3 is judged by reading out the line interval of the position and the judged information is transferred to a mouse control software part 5. The software part 5 converts a position on a corresponding display 2 from the information inputted from the mouse 4 and moves the mouse cursor to the position. Then the cursor is moved by normal operation and fine adjustment is executed. Consequently operability for the much movement of the cursor can be improved.

Title: Method for exposing image of colored electrophotography
Inventor: KITA SHINJI
IPC: G03G15/01
Filed: 1987-05-30
Abstract: PURPOSE:To obtain an image with favorable color balance without necessitating a complicated correcting means and adjustment by illuminating an original with fluorescent lamp obtained by mixing plural kinds of phosphors whose light emission peak lengths are different respectively at the time of separating the color of original. CONSTITUTION:By illuminating the original 1 with the fluorescent lamp 3 obtained by mixing plural kinds of phosphors whose light emission peak wavelengths are different respectively, at the time of separating the color of the original, the color difference between the original and a copied matter obtained by copying the original can be made small. Then, a complicated adjusting mechanism for adjusting the color balance is not necessitated and a trouble that the color balance should be adjusted while seeing copied result can be saved. Since the light emission peak wavelength of the light source itself is selected, the loss of light quantity can be made extremely small and the power consumption in the case of color separation can be suppressed low. Thus, the color balance of the image can be improved.
