Title: Magnetic substance device and magnetic sensor using the same
Inventor: MIZUSHIMA KOICHI
IPC: G01R33/06
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To perform stable operation with small current density and also to exhibit high sensitivity. SOLUTION: The magnetic sensor has the magnetic substance device of three terminals consisting of an emitter part 10, a base part 20 and a collector part 30. Schottky junction is formed by a semiconductor layer 31 to be the collector part 30 and a magnetic layered film 23 to be the base part 20. The magnetic layered film 23 is composed of two opposite magnetic films 21a and 21b holding a nonmagnetic film 22 between them. The emitter part 10 consisting of a metal film 12 and the base part 20 are connected via a tunnel insulating film 11. A value of a current to flow into the magnetic substance device is changed by changing relative relation between the magnetic films 21a and 21b in their magnetizing direction by an external magnetic field. Based on this change of the current value, the external magnetic field is detected.

Title: Printer
Inventor: SHOJI TADASHI
IPC: B41J2/44
Filed: 1990-07-19
Abstract: PURPOSE:To reduce a load on CPU and improve a processing speed by designing a program so that unnecessary image data processing can be dispensed with when the image data is output from a controller to an engine using FIFO memory and DMA. CONSTITUTION:An address management table is prepared when preparing image data on a bit image. That is, an address for each line is compared to the table when a bit image is output, and the larger address value is stored. Then if a single page-work image is prepared, the image is output. In this case, CPU1 compares the address value of each dot of image data for each line to an address value of the address management table, and if both addresses match to each other, CPU 1 sets a parity bit for FIFO memory 20 to '1' and then writes it in an address. Consequently, the first buffer 21 becomes invalid and the second buffer 22 becomes valid. Data in the second buffer is constantly set to '0' (white data), and the white data is output to a printer engine as image data in the following process.

Title: Semiconductor optical functional light-emitting element
Inventor: ASATA SUSUMU
IPC: H01S5/062
Filed: 1987-07-28
Abstract: PURPOSE:To enable an optical output having a wavelength shorter than an input wavelength by realizing light emission having a wavelength shorter than conventional devices by forming an active layer in specific superlattice structure and shaping an optical absorption section to a clad layer. CONSTITUTION:An N-type AlGaAs clad layer 13, an active layer 14 formed by alternately laminating AlAs diatomic layers and one layer or more of AlAs diatomic layers, a P-type AlGaAs clad layer 15, a current blocking layer 16, and electrodes 10, 17 are shaped onto an N-type GaAs substrate 11. The clad layer 13 includes an AlGaAs optical absorption layer 12 having forbidden band width narrower than an adjacent section on the substrate side. Since the active layer is formed in superlattice structure, direct transition emission is enabled even when a mean Al composition ratio is made higher than conventional devices (0.45), thus manufacturing a short-wave length light-emitting element. The potential barrier of the clad layer 13 is lowered by carriers generated in the optical absorption layer 12 by input beams 18, and the currents of the active layer are increased and laser oscillation is generated, thus also acquiring output beams 19 having a wavelength shorter than input beams 18.

Abstract: PURPOSE:To make printing sharp by printing a part printed with two colors in a lapped state only by a preferred color. CONSTITUTION:In such a case that a black character A is printed on a red dot part 32, when the font data 'A' is outputted from a font memory 2, since the preferential indication bit of 'A' is '1' showing black, an input data control part (IDC) 7 taking charge of black inputs the font data of '1' to a line buffer (LB) 5. When an IDC 8 taking charge of red receives a preferential indication bit '1' showing black, the IDC 8 reverses the bond data of 'A' before inputs the same to an LB 6. A signal printing red being a non-preferential color at the position when the font A must be printed is not outputted from the LB 6. That is, the action omitting the character 'A' from a part scheduled to be printed with red is performed.
