Title: Translating system
Inventor: TAKAOKA NORIKO
IPC: G06F17/28
Filed: 1987-05-28
Abstract: PURPOSE:To obtain a proper second language, by generating the second language based on several analysis results obtained in consideration of plural analyses if plural analyses of a certain part are possible in a first language including ambiguity. CONSTITUTION:An ambiguous part detecting part 2 detects an ambiguous part in accordance with an ambiguous part detecting grammar 3 on the way of Japanese-language analysis of a translation processing part 1 and writes data related to the detected ambiguous part in different analysis candidate data storage part 4. In the case of output of a different answer, the translation processing part 1 refers to the different analysis candidate data storage part 4 to check the step, where the ambiguous part is detected, and analyzes the Japanese language again up to this step. A different analysis candidate data changing part 5 changes analysis data of the ambiguous part to different analysis candidate data stored in the different analysis candidate data storage part 4 and returns the result to the translation processing part 1. The translation processing part 1 generates a different Japanese-language analysis result based on this data to generate an English sentence and outputs the different answer. Thus, the proper second language is easily obtained.

Filed: 1987-05-28
Abstract: PURPOSE:To confirm presence/absence from an arbitrary telephone set connected to an exchange at any time and from any plate, by identifying the presence/ absence with tone specification by a specific number dialed from the telephone set. CONSTITUTION:When a central processing unit 5 receives the specific numbers X1 (presence setting) and X2 (absence setting) dialed by an extension telephone set A via a register circuit 7 and a trunk control circuit 8, a presence display memory in a main memory 6 is indexed, and the data of the presence/absence (0/1) is written based on the specific number dialed to the said bit. To confirm a presence state set in such way, the specific number X3 (a number for confirming the presence state) and the extension number of an opponent desired to confirm the presence state are dialed from an arbitrary extension telephone set B. Then, the central processing unit 5 indexes the presence display memory in the main memory 6, identifies it, and a busy tone BT is connected to the extension telephone set B when the presence is confirmed, and a service set tone SST when the absence is confirmed. Thus, it is possible to confirm the presence/absence from the arbitrary telephone set connected to the exchange.

Abstract: PURPOSE:To prevent readhesion of a development waste liquor to a substrate to be treated and to reduce development defect by providing a nozzle for spraying the development liquid at a specific angle to one side from the rotary center of the substrate to be treated from the upper rear part in the direction of traveling of the one side. CONSTITUTION:A spray development device for performing development treatment by spraying a development liquid 25 to a pattern-exposed photoresist on a substrate 23 to be treated while rotating it is provided with a nozzle 24 for spraying the development liquid 25 in a fan shape at an incident angle theta of 20 to 30 degrees from the back upper part in the direction of movement of one side at the one side from the rotary center of the substrate to be treated 23 and a discharge port 21a at the upper part of the side wall of a cup 21 in approximately cylindrical shape enclosing the substrate to be treated 23. If the incident angle theta of the above development liquid is greater than 30 degrees, reflection to the upper surface side of the substrate to be treated increases. Also, if it is smaller than 20 degrees, the central opening part of the reflection-prevention plate 26 becomes larger if it is smaller than 20 degrees so that the reflection-prevention effect is reduced. Thus, the incident angle theta should be 20 to 30 degrees.

IPC: F02M69/00
Filed: 1995-05-31
Abstract: PURPOSE: To improve the air flow adjustability in low speed range to be compatible with the improvement of atomization of fuel. CONSTITUTION: In a fuel injection type engine in which a small hole 34 is drilled in a throttle valve 16 provided in an air intake passage 14, and a duel is injected to the downstream of the throttle valve 16 by an injector 28, the small hole 34 drilled in the throttle valve 16 is opened close to the fuel injection nozzle 28a of the injector 28. Since, in order to improve the volumetrical nature of air the small hole 34 provided in the throttle valve 16 is opened close to the fuel injection nozzle 28a of the injector 28, the air passing through the small hole 34 in low speed area is sprayed energetically toward the spray of the fuel injected from the injector 28. Thus, since the atomizing of the fuel is stimulated to improve the fuel consumption and exhaust gas properties, the air flow adjustability in low speed range can be compatible with the improvement of atomization of the fuel.
