Title: Method for recording/reproducing information
Inventor: SAKAEDA TATSUYA
IPC: G11B7/24041
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a recording with high resolution and with least cross-talk by recording/reproducing information in binary signal level generated by forming a bit only in a recording layer of low reflection or in a re-recording layer depending on the absorbed quantity of laser. CONSTITUTION:The recording layer 2 of low reflectance and the high-reflectance recording layer 3 are laminated on a substrate 1 in this order, or vice versa. For the substrate 1, an epoxy resin such as polycarbonate is used, a Te metal is used for the layer 3, and a pigment of polymethlene system or phthalocyanine system is used for the low-reflectance recording layer 2. And the recording layers are made in lamination-construction, so that a reflecting beam of light is obtained from the recording layer 2 in case the recording is not yet present. On the other hand, by recording only in the layer 2, a light beam reflected with the high reflectance can be obtained. Further, by recording simultaneusly in the layers 2 and 3, a reflecting beam of light is obtained only from the sub strate.

Title: Self-illumination type key switch
Inventor: MAMIYA TOSHIHARU
IPC: G06F3/02
Filed: 1994-03-22
Abstract: PURPOSE:To provide the self-illumination type key switch which is surely turned ON wherever of the key top is pressed and light in operating force and whose key top moves linearly by integrally forming the specific key top, a frame part, an arm part, a depression part and leg part in one body. CONSTITUTION:When the key top 1-a is pressed, the arm part 1-c deforms elastically, the key top 1-a moves linearly, and the depression part 1-b turns ON the switch 3. Further, when the opposite side of the key top 1-a from the switch 3 is pressed, the force which causes the arm part 1-c deform elastically is smaller than the force required to turn ON the key 3, so the key top 1-a rotates around the switch 3 downward to the right until the leg part 1-e abuts on a circuit board 4. When the key top 1-a is further pressed, the force required to turn ON the switch 3 is smaller than the force which makes the leg part 1-e deform elastically, so the key top 1-a rotates downward to the left around the leg part 1-e and the depression part 1-b turns ON the switch 3.
