Abstract: To provide an automatic analyzer which stabilizes light quantity before measurement in a short period while prolonging a long life of light source. An automatic analyzer of the present invention includes a light source with two or more LED elements each having a different wavelength, an analysis section for executing analysis based on light radiated to a reaction vessel, and a current adjustment section for adjusting quantity of current supplied to each of the LED elements. The current adjustment section reduces the quantity of current to each of the LED elements in a non-analytical state individually to be smaller than the quantity of current in an analytical state.

Abstract: A method of producing thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet-like shaped auxiliary base material are integrally molded and are made into composite material. The production method includes the steps of: heating the auxiliary base material (step S1); disposing the heated auxiliary base material in a mold (step S2); disposing the main base material in the mold via the auxiliary base material (step S3); closing the mold, and pressing together and integrally molding the auxiliary base material and the main base material (step S4); and taking out the integrally-molded thermoplastic resin composite material from the mold.

Abstract: A molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time T0), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit starts to decompress an inside of a cavity when the cavity is closed by a sealing member provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold of the metal mold (i.e., at time T2). After that, a second decompression circuit starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).

Abstract: A method and apparatus for recording data on a magnetooptical recording medium finds an optimum laser beam intensities for recording. The method and apparatus do not cause a low level P.sub.L setting to become excessively low and poor overwriting of data during overwrite recording. Recording can be accomplished changing low level and high level laser beam intensities, while holding the ratio of the low level and high level laser beam intensities constant. Data can be reproduced and evaluated. When the optimum laser beam intensities have not been determined, the intensity ratio of the low level and high level intensities can be altered. After data has been is reproduced and evaluated, the process can be repeated, until the optimum laser beam intensities are obtained. Further, recording can be based on temperature of the recording medium and surroundings to obtain optimum laser beam intensities.

Abstract: The current invention is directed to an optical storage medium system and a method for adjusting an electrically converted optical signal representing the stored data based upon the environmental or optical disk temperature and/or a heat characteristics of the optical disk.

Abstract: A stabilized overwriteable optical recording method, wherein overwriting is performed sufficiently because erasure does not become poor with the low level laser beam intensity P.sub.L being set too low. In a method of setting the recording laser beam intensity by performing test recording on an overwriteable optical recording medium, the setting of the low level recording laser beam intensity and the setting of the high level recording laser beam intensity are respectively independently performed. According to a different embodiment of the invention, another stabilized overwriteable optical recording method is disclosed. After the signal of a predetermined pattern has been recorded on an overwriteable optical recording medium, the recorded predetermined pattern is played back, and by a comparison of the pattern recovered from its playback signal with the predetermined pattern, an appropriate recording laser beam intensity is found.

Abstract: A control and method of overwrite optical recording with a first recording data transmission speed. In accordance with the method data which has been written, is verified for errors. When the number of errors exceeds a predetermined level, the data is re-recorded at the same location. The re-recording is either: 1) conducted with the same conditions; 2) conducted with a higher low level laser beam intensity; 3) conducted with the low level and high level laser beam intensities reversed; or 4) conducted after conducting a test recording and resetting the laser beam modulation intensity.
