Title: Door lock controller
Inventor: KATO HIDEAKI
IPC: G08B23/00
Filed: 1989-11-07
Abstract: PURPOSE:To secure the security of a door lock controller by registering the data of a card used at the time of opening a door and the number of passers-by as one data. CONSTITUTION:When the card is inserted into a card reader 3, a door lock controller 8 checks data for identifying a person recorded in the card and decides whether the door lock is unlocked or not.

Title: Semiconductor storage
Inventor: HOSHIDA TETSUJI
IPC: G11C29/50
Filed: 1989-11-07
Abstract: PURPOSE:To detect an abnormal amplifier circuit with a simple test by connecting the capacity to an I/O line connected to a preamplifier via an metal- semiconductor FET which is turned on by a test mode production signal. CONSTITUTION:A semiconductor storage is provided with a transfer gate which is turned on by a test mode production signal phiTE and set between an I/O line and a capacity so that this capacity is connected to the I/O line in a test mode only. Under such conditions, a signal phi3 (securing the connection between the I/O line and a main amplifier) is raised at the time t3 equal to the conventional time. Thus a preamplifier is activated and the potential difference between both I/O lines is equal to DELTAV - DELTAVTE. As a result, the potential difference is reduced by DELTAVTE. The preamplifier works after detecting the reduced potential difference. Thus an element of the defective characteristic can be effectively detected.

Title: Method for recording fixed length recording code word
Inventor: YAMAZAKI KATSUYA
IPC: G11B11/10
Filed: 1989-11-10
Abstract: PURPOSE:To attain high density recording and to reduce reproduction error due to quantization by reducing the power of a write means when a level '1' adjacent to a level '0' is recorded while levels adjacent to the level '0' of a fixed length recording code word are '1'. CONSTITUTION:An 8-bit data word is given to terminals DJN 1 - 8 and a 4/11 code word is outputted from an encoder 1. A laser power control circuit 2 checks whether or not levels adjacent to a level '0' of the 4/11 code word are '1' and when the levels adjacent to a level '0' of the 4/11 code word are '1', the control circuit 2 outputs a level '1' as information reducing the power for the recording onto a disk 6. Simultaneously, an output of the encoder 1 is outputted to a laser driver 4 via a P/S circuit 3. The driver 4 receives outputs from the circuits 3,2 to record the 4/11 code word onto the disk 6. Since the recording pattern for the level '1' aside the level '0' is recorded as a smaller pattern than the recording pattern of the level '1' of other bit pattern, even when the level '0' is interfered by the levels '1' at both sides, an RF signal level being '0' inserted between the levels '1' at reproduction is quantized without exceeding the RF signal level of other parts being level '1'.
