Patent JP-S59195306-A (JP)
Title: Recording and reproducing device of pcm signal
Inventor: ODAKA KENTAROU
IPC: G11B5/09
Filed: 1983-04-20
Abstract: PURPOSE:To attain both read-after-write and write-after-read functions with a single head by giving >=3 revolutions to a rotary head in a stop or extremely slow forward state of a tape and allotting either one of erasion, record and reproduction modes to the tape contact period of the head for each of said three revolutions. CONSTITUTION:A tape is wound obliquely around a guide drum in an angle range so as to produce a period during which a rotary head has no contact with the tape at all for each revolution of the head. Then a rotary head 1 is revolved by 90rpm, for example, equal to three times as the number of revolutions NS of a standard rotary head. Then 1/30sec, i.e. a period of three revolutions is defined as one cycle. For the right-after-read operation, the head 1 switches its operation mode every reolution to perform erasion in a period RT1 of the 1st revolution, record in a period RT2 of the 2nd revolution and reproduction in a period RT3 of the 3rd revolution during a cycle of three rotations respectively. A tape 2 is kept at pause during a period up to a 90 deg. rotary phase at the beginning of the period RT3. Therefore the head 1 scans three times the same position on the tape 2 and performs the erasion, record and reproduction respectively for each scan.

Title: Optical wavelength converter
Inventor: IKEDA MASAHIRO
IPC: G02F2/00
Filed: 1982-04-26
Abstract: PURPOSE:To obtain an optical wavelength converter which converts an input light signal directly to an output light signal differing in wavelength by providing a semiconductor P-N junction element having a special function and an optical filter. CONSTITUTION:A source voltage VB is applied to a semiconductor P-N junction element 4 such as semiconductor laser and the element is grounded through a load resistor RL, whereby the implantation current I0 larger than an oscillation threshold is supplied to the element 4. An input light signal of a wavelength lambdai is implanted into the active layer of the element 4 from one terminal thereof and an output light signal is drawn out from the other terminal. The output light signal is passed through an optical filter 5 using, for example, an optical demultiplexer, so that only the light signal of the oscillation wavelength lambdam of the element 4 among the output signals is passed therethrough, whereby the conversion of the optical wavelength is accomplished. Here the phases of the input light signal lambdai and the output light signal are inverted, but the output signal of the same phase is obtainable by performing the similar conversion of the optical wavelength again.

Title: Full range operational amplifier
Inventor: OYA MITSUNARI
IPC: H03F3/68
Filed: 1989-03-22
Abstract: PURPOSE:To attain accurate voltage follower and voltage comparison operation even when an input voltage ranges from a ground voltage level to a power voltage level by covering a 1st inoperation region with a 2nd operating region and covering a 2nd inoperation region with the 1st operating region. CONSTITUTION:When an input voltage Vi exists between a maximum input voltage Vi-a power voltage Vcc, the input voltage Vi stays in a 1st operating region VTH21. Thus, a Schmitt buffer 23 outputs an H level control signal S1 being a 1st control signal. Thus, an analog switch 24a is closed and the same voltage as the input voltage Vi is generated at an output terminal 25. When the input voltage Vi exists between a ground voltage level Vss and a minimum input voltage level Vimin, the input voltage Vi stays in a 2nd operating region VTL2. Thus, The Schmitt buffer 23 outputs an L level control signal S2 being a 2nd control signal. Thus, an analog switch 24b is closed and the same voltage as the input voltage Vi is generated at an output terminal 25.

Title: Low nox burner
Inventor: MURAI EIJI
IPC: F23C99/00
Filed: 1984-04-09
Abstract: PURPOSE:To reduce production of NOx, by a method wherein partitions, respectively limiting the supply of the air to each burner, are respectively mounted to combustion chambers. CONSTITUTION:The air, required and sufficient for combustion, is sucked through an air suction part 6 by means of gas injected to a mixture pipe 3 through a nozzle 4, and is burnt in a burner part (a flame port part) 5. The burner part 5 performs combustion in a combustion chamber 1 which is constituted entirely airtightly except an exhaust gas exhaust part. Plural burners are located in the combustion chamber 1, and a partition 2 is situated in the combustion chamber corresponding to each burner. The partition 2 serves to individually completely partition the burners 5 from each other so that one combustion chamber has one burner. By means of the partition 2, the flow of the air from the outside through a part except the air suction part 6 is shut off, and individual and independent combustion is effected by the burner, and this, even when a gas amount is desired to be throttled or the plural burners are operated in a flickering manner, prevents increase of an NOx amount, resulting in provision of excellent combustion.
