Title: Method and device for electron beam magnetic recording and reproducing
Inventor: MISHIMA SACHIKO
IPC: G11B9/10
Filed: 1990-06-22
Abstract: PURPOSE:To enable the recording with higher density than a magneto-optical recording method by irradiating a magnetic recording medium with an electron beam and detecting the electron beam changed in its reflecting direction by a leakage magnetic field from this magnetic recording medium. CONSTITUTION:When the magnetic recording medium 32 is irradiate with the electron beam 13, the temp. of the irradiated part is raised up to the vicinity of the Curie point, and coercive force of the recording medium in the irradiated part is decreased. In this case, by working an external magnetic field, the direction of magnetization is changed in accordance with the magnetic field. Consequently, by changing the direction of the external magnetic field in accordance with information to be recorded, the direction of the magnetization corresponding to this information can take place. The magnetic recording medium 32 is irradiated with the electron beam 13, and the electron beam changed in its reflecting direction due to the Lorentz effect by a magnetic field generated from the medium 32 is detected by using plural electron beam detectors 9 and converted into a reproducing output. By this method, the high recording density is feasible.

Title: Constant-voltage power source circuit
Inventor: HARAKAWA TAKAO
IPC: G05F3/24
Filed: 1979-12-21
Abstract: PURPOSE: To obtain excellent temperature characteristics without reference to variance of characteristics of a semiconductor, by controlling the variable resistor, providing voltage control, with an output signal obtained by detecting variation in output voltage so that output fluctuations of temperature will be small.  
     CONSTITUTION: Analog switches are composed of CMOSs 20 and 21, and 22 and 23 respectively and their on resistances vary with gate-source voltage VG. For this purpose, voltage VG is controlled to eliminate manufacture variance of base-emitter voltage VBE between bipolar transistor TRs 1 and 2. Then, the output detecting and resistance control circuit composed of MOSs 10W13 detects output voltage VO and, if VO drops, reducing gate voltages of MOSs 20 and 23 by raising gate voltages of MOSs 21 and 22, thereby controlling values of on resistances so that the variation of voltage VO with temperature will be reduced. Thus, the constant-voltage power source circuit with excellent temperature characteristics can be obtained without reference to manufacture variance of base-emitter voltages of TRs 1 and 2.

IPC: H01S3/06
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a device which generates a 0.48 μm band induced emission beam at high efficiency. SOLUTION: Reflectors 12 and 14 of 1.12-1.14 μm are arranged on both sides of an Nd-doped fiber 10, forming a resonator. An exciting LD16 generates a 0.8 μm band excitation beam. The 0.8 μm band excitation beam passes through the reflector 12 before coming into the fiber 10, and a part of it excites the Nd of the fiber 10, while a remaining part transmits the fiber 10 and the reflector 14 before entering a Tm-doped optical fiber 18, to excite the Tm of the optical fiber 18. Nd excited with the 0.8 μm band beam generates a 1.12-1.14 μm beam, and the resonator comprising the reflectors 12 and 14 causes laser oscillation. The 1.12-1.14 μm band laser beam passes through the reflector 14 and then enters the Tm-doped optical fiber 18, exciting the Tm contained in it.  The Tm generates 0.48 μm band beam by the excitation of the 0.8 μm band beam and the 1.12-1.14 μm band beam.

Abstract: PURPOSE:To prevent a printed circuit board from being damaged by creating a test pattern and an output expectation value with test wirings as a ground potential and a power supply potential and then detecting the short-circuiting failure with the power supply wiring and the ground wiring with these as input. CONSTITUTION:A test pattern and the output expectation value are stored in a first memory 16 inside a tester 15. First and second patterns with the test wiring at the ground and power supply sides are created along with the output expectation value. Then, either test pattern is taken out of the memory 16 and then is input to a target printed circuit board 11. The output value from the printed circuit board 11 is stored in a second memory 18. The output value is compared with the output expectation value and then short-circuiting with the power supply wiring and the ground wiring with the second pattern are pointed out when they do not agree. When the output value agrees with the output expectation value, it is judged that no failure occurred. When a short-circuiting failure is detected, the power is turned off, thus preventing the printed circuit board from being damaged.
