Title: Detecting method of recording of optical disc
Inventor: ICHII HIROSHI
IPC: G11B7/004
Filed: 1982-07-28
Abstract: PURPOSE:To improve the efficiency of writing processing, by outputting an error signal only when the length of an error burst exceeds the previously fixed length in the range of error burst length to be corrected by an error correcting code. CONSTITUTION:Reflected light passed through a lens 12 is converted into an electric signal by an optical sensor 13, amplified by an amplifier 14 and sent to another circuit such as an unshown automatic focus controlling circuit or tracking circuit. A pit checking circuit 15 analyzes a reflected light detecting signal outputted from the amplifier 14 to check whether the size and shape of a recording pit is included in a reference value or not. The shown pit checking circuit 15 checks the normality of the recording pit by slicing and taking out an overshoot part S1 and an undershoot part S3 out of the reflected light waveform, measuring the time between the S1 and S3 and then comparing the measured result with the previously set up reference value. At the detection of the abnormal pit, the pit checking circuit 15 outputs an error signal.

Title: Battery voltage monitor
Inventor: TAKAHASHI MASAHIKO
IPC: H02J7/00
Filed: 1993-06-02
Abstract: PURPOSE:To hold back-up for a memory without interruption caused by exhaustion of a battery, by detecting a voltage before the complete exhaustion and promoting battery exchange. CONSTITUTION:A load current larger than a load current in a bake-up operation of a memory 3 is carried from a memory back-up battery 4 through a serial circuit of a resistor 8 and a switching element 9. When the capacity of the battery 4 is consumed considerably, the output voltage from the battery 4 is lowered extremely below that in a normal back-up state so that alarm for a promotion of battery exchange can be generated before the battery is exhausted. Consequently, the back-up operation can be protected from interruption caused by the complete exhaustion of the battery 3.
Patent JP-H11320940-A (JP)
Title: Recorder
Inventor: TERAO KENJI
IPC: H02P8/12
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To utilize power effectively by an arrangement wherein a motor power control means determines the power of a carrying pulse motor, when it is switched to low level, as the recording power for a recording element. SOLUTION: Coil current of a pulse motor is increased/decreased depending on the level of an MAC signal (control signal) for controlling the coil current. The motor coil is driven with a constant current and a large current is fed to the motor coil when the MAC signal has H level whereas a small current is fed to the motor coil when the MAC signal has L level. During time intervals of t1-t4 and t5-t6, the MAC signal goes H to increase motor power and maximum level of recording power is lowered because the number of black pixels to be driven is limited. Since recording power is suppressed and excess power can be distributed as motor power, power can be utilize effectively.

Title: Constant flow rate device for faucet
Inventor: INADA SETSUKO
IPC: F16K17/30
Filed: 1994-05-10
Abstract: PURPOSE:To enable the flow rate of water to be increased in excess of a specified value by providing a bypass in addition to a main flow passage that passes through a constant flow valve and controls the flow rate, and freely opening or closing the bypass by control of a manual knob or lever. CONSTITUTION:When the handle of a faucet main body 1 is opened, a water flow reaches a water discharging portion 22. The water flow passes through a port 222a and a constant flow valve 223 from a port 221a, reaches a water chamber 222c and is discharged. The flow rate is set to a value specified by the constant flow valve 223. Then, when a knob 224 is rotated to communicate a port 222b with the port 221 a, the water flows directly to a water chamber 222d from the port 221a through the port 222b, increasing the overall flow rate. The ports 221a, 222a, 222b are configured so that the rate of change of the flow rate with respect to the rotation angle of the knob 224 is set to an optimum value. Therefore, the flow rate is held constant irrespective of the opening of the faucet handle and the degree of the water pressure, thereby ensuring that a water saving effect can be produced.
