Title: Writing method of disc
Inventor: TOYAMA TAKEO
IPC: G11B7/0045
Filed: 1982-10-29
Abstract: PURPOSE:To write precisely data on a disc by irradiating a track uniformly by laser light with prescribed intensity during one or plural revolutions of a disc to preheat the track concerned. CONSTITUTION:When a track to be written is the track of the external periphery part of the disc, the supply of high-frequency current to a laser diode 7 is cut off and the track is uniformly irradiated by the laser light with the fixed intensity based upon the preheating output of the laser diode 7 during one or plural revolutions of the disc to preheat the track concerned.

Title: Reader for matrix-shaped switch group
Inventor: OKUHARA HIROO
IPC: G06F3/0488
Filed: 1983-10-14
Abstract: PURPOSE:To read accurately a combination of plural switches turned on by transmitting a drive signal to each line of a matrix-shaped switch group from a driver part and then fetching a sensor signal to a buffer input part. CONSTITUTION:When an address 01 is designated by a microprocessor 1, a driver signal is transmitted from a line La1 of a driver part 2. While a sensor signal corresponding to a pushed switch is fetched to a buffer gate 3. Then a switch turned on is detected by changing the addresses designated to the part 2 to 10 and 11 from 01 to detect a sensor signal. At the same time, an AND is compared with an OR for the sensor signal obtained by the driver signal which is transmitted every transmission address. Then the generation of an error is decided when no coincidence is obtained between the AND and the OR. In such a way, the misdetection due to detouring can be avoided.
