Title: Tool chuck
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/00
Filed: 1991-11-11
Abstract: PURPOSE: To utilize the turning force of a nut ring effectively for clamping force for a tool by interposing a washer, the outside surface of which is coated with a solid lubricating film at the inner end of the nut ring to reduce the frictional resistance between the nut ring for advancing a chuck claw and a fixed part brought into contact therewith. CONSTITUTION: When a nut ring 6 is turned in the clamping direction according to the rotation of an operating ring 8, a chuck claw 4 is shrunk to abut on a tool A, and when the clamping force is applied to the chuck claw 4 by the turning force of the nut ring 6, the nut ring 6 is moved back by the reaction force of the chuck claw 4 so that the inner end face of the nut ring 6 is pressed to the opposite fixed parts 13, 14. A washer 14a, the outside surface of which is coated with a solid lubricating film 14b is interposed therebetween. Therefore, the mutual frictional resistance is reduced so that the turning force of the nut ring 6 is effectively used for clamping force for the tool A to clamp the tool A.

Abstract: PURPOSE:To obtain a good and uniform characteristic by forming an electrode which comes into contact with the top part of a protrusion part on an ohmic contact layer and with the surface of a Schottky contact layer. CONSTITUTION:An AlGaAs layer 6 is formed additionally on a GaAs contact layer 5; a photoresist 11 is coated so as to make the surface flat; the photoresist 11 is removed partially, by a dry etching operation, so as to reveal a protrusion part on a wafer.

IPC: G10L15/22
Filed: 1987-12-22
Abstract: PURPOSE: To improve serviceability and shorten the hold time of the device by synthesizing the speech of a recognition result and sending it back to the speaker each time one word is inputted, and deciding that the word is recog nized correctly unless a next input speech from the speaker is detected as a specific word indicating an error of the recognition result. CONSTITUTION: A 1st word is inputted and a speech recognition part 12 recognizes the 1st word and outputs the recognition result to a control circuit 14. The control circuit 14 sends a code corresponding to 'Once more' to a speech recognition part 13 when the recognition result is 'No', and a synthesized speech is sent to the speaker, so that a return to the input of the 1st word is made. When the recognition result is not 'No', a code corresponding to the recognition result is sent to the speech synthesis part 13 and when the recognition result is not 'End', a 2nd input state is entered. When the recognition result is 'End', a code corresponding to 'End' is sent to the speech synthesis part 13 and the recognition results of the 1st-final words are outputted to an external processor. Consequently, an error in speech recognition can easily and immediately be corrected.

Abstract: PURPOSE:To detect a preceding vehicle accurately without being influenced by a guidance plate or the like and to find a distance between two vehicles by installing a vehicle discrimination means which extracts data indicating a vehicle out of angle data and distance data and a vehicular gap output means which discriminates an object mark on the running traffic lane of an own vehicle and which outputs its distance. CONSTITUTION:Electromagnetic waves are swept to the right and left directions and sent out, and a distance up to a reflecting object is found on the basis of reflected waves at every sweep angle. When a plurality of reflected waves exist at the same sweep angle, distances can be found regarding the respective waves. Out of the distances which have been detected, data indicating a vehicle is extracted by a vehicle discrimination means 7. In addition, a vehicular gap output means 9 discriminates a vehicle which is situated on the running traffic lane of an own vehicle, and its distance is judged to be a vehicular distance. Even when a fan beam laser whose up-and-down spreading angle is large is used, the vehicle is discriminated by the vehicle discrimination means 7 even when it is subjected to reflected waves from a guidance plate or the like, and the vehicular distance up to a preceding vehicle can be obtained accurately.
