IPC: G01J1/42
Filed: 1982-09-10
Abstract: PURPOSE:To enable the detection of not only the sensitivity of a detector but also the degree of contamination on the housing wall in a dark room without adding any photodetector as a test system, by adding the specific quantity of the light emitted from a test light emitter in the stage of testing and stopping the same in the stage of monitoring. CONSTITUTION:When a fire arises and smoke particles M fill the room increasingly, the scattered light B for monitoring is made incident to a detector R1 for monitoring light, which generates a fire signal FI. A controller CL acts to control a test light emitting device L3 so as to emit test light T together with a monitoring light emitting device L1 in the stage of testing the detector. The test light T is reflected and scattered by the housing wall F in a dark room, and the total sum E of the test scattered light is made incident to a photodetector F1 for monitoring, which detects the same as the fire signal FI when the alarming level is attained, thus the operation test of the detector is accomplished. The difference between the quantity of the total emitted test light T by which the detector is operated and the light A emitted for monitoring in the stage of ordinary monitoring is beforehand set at n-times (or 1/n times) of the light A emitted for monitoring and the sensitivity of the detector and the degree of comtamination of the housing wall in the dark room are tested and detected from the value of said difference.

Title: Accent phrase division system
Inventor: SAKAYORI TETSUYA
IPC: G10L13/10
Filed: 1988-06-24
Abstract: PURPOSE:To easily extract a proper accent phrase by detecting a word forming an accent phrase border and setting the accent phrase nearby the word. CONSTITUTION:A flag which indicates an isolated/semi-isolated word is prepared as an item of a word dictionary used for morpheme analytic processing to easily decide an isolated or semi-isolated word. Then when the isolated word is found, division positions are set right before and behind the isolated word to obtain three divided accent phrases; when the semi-isolated word is found, a division position is set right before the semi-isolated word to obtain two divided accent phrases. Thus, the word which forms the accent phrase border without fail is detected without using a mora number, etc., and the accent phrase border is set nearby this word. Consequently, an accent phrase suitable for speech text synthesis is extracted.

IPC: C30B23/06
Filed: 1993-06-28
Abstract: PURPOSE:To provide a silicon carbide single crystal-producing device capable of producing the silicon carbide single crystal excellent in the quality and in the stability of the quality. CONSTITUTION:Silicon carbide powder 2 is received on one side of a crucible 1 in the face of a seed crystal disposed on the other side of the crucible 1. The crucible is surrounded with an upper heater 7 and a lower heater 8. The upper heater 7 comprises plural sweeping heaters 7b1-7b3 capable of being independently controlled so that a sublimation zone is successively transferred upward from the seed crystal side. The sublimation zone can be transferred by lowering the crucible 1 during the sublimation. Since the silicon carbide powder 2 is successively sublimed from the side of the seed crystal in the device, the sublimed gas is continuously poured on a crystal-growing surface under the same condition, and the growth of the crystal is continuously performed. Thereby, the silicon carbide single crystal excellent in quality and in the stability of the quality is obtained without changing the quality along the growing direction.
