Title: Magnetooptical recording method and magnetooptical recording medium
Inventor: WATADA ATSUYUKI
IPC: G11B11/105
Filed: 1991-07-05
Abstract: PURPOSE:To enable easy overwriting by applying a magnetic field in the opposite direction from a recording magnetic field and inverting the magnetic moment of a 1st magnetic layer only at a part where a magnetic wall is present between the 1st magnetic layer and a 2nd magnetic layer. CONSTITUTION:A magnetic field Hi is applied to the medium to uniformize the magnetic moment of the 1st magnetic layer 2 to one direction. Then while the recording magnetic field Hw is applied in the same direction with the magnetic field, recording laser power is varied between binary levels corresponding to a recording signal, which is recorded. When '0' corresponds to a case wherein the direction of the magnetic moment of the layer 2 is opposite from the direction of the magnetic field Hw and '1' corresponds to a case wherein the direction is the same, a bit of '0' is irradiated with high-level laser light to raise the temperature of the magnetic layer to Tb and the magnetic wall is formed between the layers 2 and 3 since the temperature difference between the layers 2 and 3 is small and an exchange coupling force is small. There, a magnetic field Hx is applied in the opposite direction from the magnetic field Hw to invert the magnetic moment of the layer 2 only at the part where the magnetic wall is present between the layers 2 and 3. Consequently, the overwriting is performed.

Title: Supplying current source circuit working at low voltage
Inventor: KAJIWARA JIYUNJI
IPC: H03K19/091
Filed: 1982-10-30
Abstract: PURPOSE:To ensure the stable working of a current source circuit down to a low level of voltage, by using the collector current of a transistor circuit containing an emitter-base diode circuit set in parallel to a constant voltage source as a reference current of a current mirror circuit and then applying the output of the current mirror circuit to an ILL. CONSTITUTION:A constant voltage source VREF is provided with a band gap reference circuit and used as a reference power supply having a temperature coefficient set approximately at zero. For an npn transistor TRQ1, the base, emitter and collector are connected to the source VREF, a resistance R1, and the base and the collector of a pnp TRQ2 as well as the base of a pnp TRQ3 respectively. The current I1 flowing to the resistance R1 connected between the emitter of the TRQ1 and an earth is set at (VREF-VBE1)/R1, where VBE1 shows the base-emitter voltage of the TRQ1. This current I1 flows to the TRQ2, and the injecting current Iinj is set equal to the current flowing through the R1 by TRQ2 and Q3 which constitute a current mirror. Thus an IIL circuit 1 can be made to have the stable working down to a low level of power supply voltage.

Filed: 1990-07-20
Abstract: PURPOSE:To enable judgment of waviness or brakage of a welding line according to the number, the length and the like of parts to be detected by detecting parts where welding is accomplished perfectly outside a width preset with respect to the center of a welding width. CONSTITUTION:In a welding width deviation position detecting program 17b, the number of pixels and position coordinates thereof crossing width lines D3 and D4 are detected to be stored into a welding deviation defect data memory area 17d. These detection values stored in the welding deviation defect data memory area 17d refer to welding points crossing a welding limit width and the number of the pixels clarifies how wavy a welding is. This also makes clear the state of occurrence, spreading and frequency of disorders of arc in a welding robot. This enables the adjusting of the welding robot before a poor welding is caused by the waving and breaking of the welding line, a change in the welding width and the like. This can prevents occurrence of undesired hardening and an annealed part thereby achieving a higher quality.
