Abstract: PURPOSE:To reduce the number of parts and to contrive a low cost by making the shaping plane of a beam shaping prism have the function of an optical path separation plane to an optical detecting system and making the beam shaping plane to be a non-vapor-deposited plane. CONSTITUTION:A light beam emitted from a laser diode 1 is made incident on the non-vapor-deposited plane 3p of the beam shaping prism 3a via a coupling lens 2. The light beam is almost passed through the plane 3p since a P polarization transmissivity in the plane 3p is >=90% and the cross-sectional from of the beam is made to be a complete to be made incident on a 1/4 frequency plate 4. Then, the beam becomes to be a circular polarized light and irradiates a media 7 via a deflection prism 5. The reflected light from the media 7 is made incident on the 1/4 frequency plate 4 to be converted to an S polarized light and is made incident on the prism 3a. At this time, the light more than 15% of the incident S polarized light is reflected at the plane 3p and is made incident on a magneto-optical signal detecting system 9 via an objective lens 8 and then signals corresponding to information are detected. Thus, the constitution of a device is made simple and the low cost is contrived because the prism 3a is served as a beam splitter.

Title: Electric power trouble recovery loop
Inventor: FUIRITSUPU BUIHITO
IPC: G06F11/14
Filed: 1992-07-29
Abstract: PURPOSE: To prevent lock-up of a meter by looping a program in a routine, where a non-volatile memory is not referred any more, until detecting the rise of a second power after detection of disappearance of a first power. CONSTITUTION: If the first power disappears, a CPU is interrupted by PF. Then, a processor enters into a fixed routine 62 after performing an update processing 61 of important data which stops a machine process in accordance with a rule or the like. In the fixed routine 62, processing to refer to the non-volatile memory is not performed at all. If the first power disappears, the second power rises to backup the power. When this rise of the second power is detected, the processor escapes the fixed routine 62 and returns to the normal processing. If backup is not normally performed, the processor is stopped in the fixed routine 62. Thus, lock-up of the meter is prevented.

Filed: 1994-08-03
Abstract: PURPOSE:To reduce a failure generation frequency and enhance reliability by generating conductive state in the electrodes of a magnet core and an electromagnet core, depending on the existence of coil current. CONSTITUTION:When a switch 4 is turned off, excitation with a coil does not take place in a magnet core 3b and an electromagnet core 3c. Thus, a line of magnetic force is formed between the cores 3a and 3b. Magnetic particles 1c keep electrical continuity between electrodes 2a and 2b, according to the line of magnetic force, and continuity output is obtained from C and N terminals. When the switch 4 is turned on, excitation with the coil 5 takes place between the cores 3b and 3c, and the line of magnetic force existing between the cores 3b and 3c disappears. Instead, a new line of magnetic force is formed between the cores 3a and 3b. Then, the magnetic particles 1c keep electrical continuity between the electrodes 2a and 2b according to the new line of magnetic force, and continuity output is obtained from C and R terminals.

Abstract: PURPOSE:To make a laser device of this design small in size and to decrease it in cross talk by a method wherein a fiber array is used as an optical waveguide between a semiconductor laser array and a photodetective element array, and the whole body is hermetically sealed up. CONSTITUTION:A semiconductor laser array 3, a fiber array 2, and a photodetective element array are fixed to a fiber fixing table 1, which is hermetically sealed up. Light rays traveling through the fiber array 2 are incident on the photodetective regions of the photodetective element array 4. The incident light rays are converted into electrical signals through the photodetective elements 4, which are fed back to the laser chips. As the space between the cores inside the fiber array 2 is equal to the pitch of the light emitting points of the semiconductor laser array 3, the fiber array 2 and the laser array 3 are directly coupled, therefore cross talk can be eliminated and laser rays of the laser array can be separately guided to the cores of the fiber array 2.
