Title: Information signal recording method
Inventor: ITONAGA MAKOTO
IPC: G11B7/00
Filed: 1989-06-30
Abstract: PURPOSE:To record multi-level information on the signal recording surface of a recording medium with high density by forming respective pits constituting a pit train while being separated from the center of a track only by a certain deviation distance corresponding to the multi-level information to be recorded. CONSTITUTION:The ternary information or quaternary information can be recorded on the recording surface in the same size as that of an optical disk, to which the binary information are recorded, with the high density. Namely, light beam from a laser light source is divided into plural beams and an optical spot is acquired by respectively executing intensity modulation or deflection modulation to the plural light beams, which are acquired by the division, corresponding to the ternary or quaternary information to be recorded. Then, an interval between adjacent track centers 4 or the center of the track is irradiated with the optical spot while keeping a fixed deviation distance DELTA on the both sides of the track center 4 and the pit train is formed. Afterwards, the ternary or quaternary information are recorded. Thus, the information signal is accurately recorded with the high density.

Title: Bus protective relay
Inventor: EDA NOBUO
IPC: H02H3/38
Filed: 1994-07-22
Abstract: PURPOSE:To make the transfer of current data between digital relays for division unnecessary by inhibiting the output of the trip commands corresponding to both buses on both sides of a bus section disconnecting switch in accordance with the operation of either one of the relays corresponding to both buses when the disconnecting switch is closed. CONSTITUTION:A non-segregated digital relay 11 corresponds to a plurality of buses. Segregated digital relays 12-1 and 12-2 respectively perform ratio differential calculation by using the sum of instantaneous values of current data of their corresponding buses as operating amounts and the absolute values or maximum values of the absolute values of the instantaneous values as suppressing amounts. The shortcircuit directional relay of each bus performs direction discriminating calculation by using the instantaneous value of voltage data of the bus as a reference amount and the instantaneous value of current data as a comparing amount and operates in accordance with the flow-out direction of the electric current from the bus. When a bus section disconnecting switch is closed, the output of the trip commands corresponding to both buses is inhibited in accordance with the operation of either one of the directional relays corresponding to the buses on both sides of the disconnecting switch. A bus protective relay is constituted so that the relay can inhibit wrong interruption by adding a new directional relay to each bus.

Title: Display device for remaining time
Inventor: KAWABE MASARU
IPC: F24C7/02
Filed: 1984-08-17
Abstract: PURPOSE:To display the remaining time by comparing the output voltage of a charging and discharging means with a set reference voltage and deciding on power feeding to a load or a power failure, and comparing the output voltage of the charging and discharging means with the voltage-division value of the reference voltage and turning on or off display elements successively. CONSTITUTION:When a contact 12 is made and a DC power source is formed, the voltage at the voltage division point between a variable resistance 18 and a resistance R19 is further divided by R26-R29 and inputted to inverted input terminals of comparators 30-33. A capacitor C21, on the other hand, is charged and its voltage is low right after the start of charging, so the comparators 30- 33 operate to turn on all light emitting diodes LD35-LD38, showing that the remaining time of a timer is long. As the charging voltage of the C21 rises, the voltage at the uninverted input terminal of the comparator 33 rises above the voltage at the inverted input terminal and the output of the comparator 33 rises to H, so that the LD38 turns off. Similarly, the LDs 37 and 36 turn off and then the LD35 turns off on the completion of the timer time. Thus, the remaining time is displayed.
