Title: Protection of semiconductor laser and protective circuit
IPC: H01S5/042
Filed: 1992-03-13
Abstract: PURPOSE:To stop reliably a current supply to a semiconductor laser even in the case where an abnormal state, such as a trouble in a first-stage amplifier, is generated in a luminescent power detecting part and to make it possible to prevent the laser from being broken down. CONSTITUTION:Before a semiconductor laser is lighted, an output voltage of a current-voltage conversion circuit 3 is detected by a voltage detecting circuit and the detected result is held by a holding circuit 10, whereby when the output voltage of the circuit 3 is abnormal, a current supply stopping means 7 is actuated and the laser 1 is not lighted. Thereby, the normal state or abnormal state of the output voltage of the circuit 3 can be confirmed and in the case where the output voltage is abnormal, a current supply to the laser 1 is stopped. Accordingly, the more reliable protection of the laser 1 becomes possible.

The solid is porous and may be capable of absorbing at least 0.6 cm<3> of ethanol per gramme of solid. The particulate solid may be obtained by spray drying a non-particulate material, preferably by comminuting the non-particulate material in the presence of a liquid medium, and desirably an attrition inhibitor, and spray-drying the comminuted mixture. The particulate solid can be reacted with a transition metal compound such as titanium tetrachloride and preferably with a Lewis Base compound such as the ester of an aromatic carboxylic acid. The transition metal composition obtained is useful for the production of olefin polymerisation catalysts of high activity and stereospecificity. The polymers obtained have an essentially spherical particle form and are porous, for example having a porosity of at least 0.2 cm<3>/g as measured by mercury porosimetry. The polymers typically have a mean particle size of at least one millimetre.

Filed: 1993-04-15
Abstract: PURPOSE:To greatly shorten the heating-up and cooling-down time of a substrate and further to decrease the dispersion in film properties, such as composition among the substrate installing positions in a method where a thin perovskite type oxide dielectric film is formed by irradiating infrared rays from outside a reaction chamber where dielectric compounds are deposited to heat the substrate. CONSTITUTION:In a sputter chamber 1, a sintered oxide ferromagnetic body material, such as Pb0.79La0.21Ti0.95O3 (further sintered 0-40mol% in excess of PbO) is fitted to be used as a target. A substrate 3 is a MgO single crystal one. Infrared rays emitted outside a reaction chamber pass through a quartz glass plate 4 of 5in. diameter and 3mm thickness fitted on the cover of the sputter chamber and enter a vacuum tank. And the infrared rays heat the back of a substrate holder 5 on which the MgO substrate is fitted by radiation. As a result, the heat conducted from the substrate holder 5 causes the substrate 3 to be heated.

IPC: H04N1/00
Filed: 1995-04-14
Abstract: PURPOSE: To prevent line interruption due to a communication error by adding transmission disable information to an NSS signal and sending the resulting signal to a receiver facsimile equipment when transmission image data quantity is too excessive through the discrimination of a residual capacity of a recording medium. CONSTITUTION: The maximum available capacity of a memory 17 is entered by a prescribed operation at the initializing. Then a CPU 1 stores it to a built-in memory. Every time received image data corresponding to one recording paper sheet are stored in the memory 17, the capacity equivalent to the received image recording is subtracted from the current memory capacity. The residual amount of the recording paper P and the residual capacity of the memory 17 representing the possible recording capacity of the received image data are stored in the built-in memory of the CPU 1 by storing the difference to the built-in memory. When the transmission image data amount is excessive and no residual capacity is in existence, a 2nd transmission means adds transmission disable information to an NSS signal and sends resulting signal to the facsimile equipment. Furthermore, it is displayed on a display circuit 10, the user easily receives the notice.
