IPC: F04C28/26
Filed: 1988-09-21
Abstract: PURPOSE:To enlarge a flow passage area when gas during compression is released, augmenting a refrigerant quantity being released, and make a large capacity variation performable by installing more than two pieces of an opening to the inside of a cylinder in a capacity variable device. CONSTITUTION:Two pieces of an opening 16 opened to the inner part 6a of a cylinder 6 as lined up in the axial direction.

Title: Manufacture of integrated circuit
Inventor: LEE JEAN LING
IPC: H01L21/8238
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce a generation of counter-doping due to cross diffusion, by sequentially laminating a polysilicon blanket layer, a titanium layer, a titanium nitride layer and a fireproof metal silicide layer, and by forming a gate stack while patterning the laminate. SOLUTION: A first portion 171 of a polysilicon blanket layer 17 is a P-doped n<+> gate, and a second portion 172 is a B-doped p<+> gate. However, when the n<+> gate comes in contact with the p<+> gate, counter-doping occurs. To overcome this problem, the layer 17 is covered with a titanium layer 19. The layer 19 improves the gate resistance, so that a getter for B is provided. Note that a titanium nitride layer 21 forms a barrier against the diffusion of B and P, thereby preventing the occurrence of counter-doping. As a result of this gate structure, diffusion through a fireproof metal silicide layer 23 formed on the structure occurs little.

Abstract: PURPOSE:To coat sufficiently an optical fiber without any sticking of air bubbles by providing a pressure difference between the upper and the lower space of a vessel contg. a liquid resinous composition with a pump equipped to a connecting pipe to increase the moving speed of the liquid resinous composition. CONSTITUTION:A naked optical fiber 3 obtained by wiredrawing a rod-shaped parent glass material 1 in a heating furnace 2 is passed through a coating device 4 of a liquid resinous composition, and the liquid resinous composition 5 is coated. Then the liquid resinous composition 5 coated on the surface of the optical fiber is cured in a heater 6, and the optical fiber 7 coated with the resin is obtained. In this case, the coating device 4 of the liquid resinous composition is provided with a container 41 of the liquid resinous composition 5 and a tube 44 for connecting the upper space 42 with the lower space 43. Since the pressure in the upper space 42 is made higher than the pressure in the lower space 43 by a pump 45, the moving speed of the liquid resinous composition 5 is increased. Accordingly, the optical fiber 3 is sufficiently coated, and the sticking of air bubbles is prevented.

Filed: 1988-09-21
Abstract: PURPOSE:To facilitate the consecutive recording by moving a head back and forth alternately in combination of a head position (MFB) control with a tracking control. CONSTITUTION:With regard to an information recording and reproducing device capable of recording and reproducing both information signal and tracking pilot for a recording medium with the same head at the same time, it possesses a tracking control means for performing the tracking of the head by utilizing the tracking pilot and an MFB control means for moving the head to fulfill a target value by detecting a position of the head. Thus, when the head is to be moved back and forth and also positioned, the presence of a recorded signal on a track where the head 14 is positioned is detected by a position detecting part 46. Then, from this detected result, the final recording track is detected, and the head 14 is positioned to be capable of tracking in the vicinity of the final recording track. By this method, the final recording track is automatically and excellently detected, and the consecutive recording can hence be facilitated.

Abstract: PURPOSE: To improve a recognition rate by the small quantity of calculation by providing the voice recognition device with a learning part for changing the start and end frames of a reference pattern registered in a storage part by learning. CONSTITUTION: A voice inputted from a voice input part 1 is segmented to consonant parts and vowel parts in each single sound by a segmentation part 2, feature parameters are calculated by an analysis part 3 and a matching part 5 executes soft matching based upon the calculated values, the segmented values, and calculation values and segmentation values stored in a reference pattern storing part 4. Then jdugement part 6 judges the existence of misrecognition by comparing the inputted data with the characters of a correct answer inputted by a teacher, and when misrecognition exists, learning is executed at least by a learning part 7. Thereby the frame length of the reference pattern is optimized by learning and only the consonant start frame and consonant end frame of the reference patterns are changed.  Consequently the quantity of calculation is extremely reduced and the recognition rate is improved.

Title: Sampling and dispensing nozzle of automatic biochemical analysis instrument
Inventor: TAMAYAMA YASUKO
IPC: G01N35/10
Filed: 1984-11-14
Abstract: PURPOSE:To have a function for detecting a liquid level as well as an effect of reinforcing a nozzle part by providing a liquid level detecting part consisting of the nozzle part and a pair of electrode materials. CONSTITUTION:A sampling and dispensing nozzle 1, the nozzle part 2, the liquid level detecting part 3 and the electrode materials 4, 5, etc. are provided. The nozzle part 2 and the electrode materials 4, 5 of the detecting part 3 descend simultaneously and when both top ends of the materials 4, 5 dip into a reagent or sample, the two top ends are conductive with the reagent, etc. and are therefore made conducting in the stage of suction and sampling of a reagent or sample. Then a detector 14 can detect the liquid level and the subsequent descending of the nozzle 1 is stopped. When the materials 4, 5 fail to attain the conducting state, the detector 14 can transmit the emptiness of the reagent, etc. to the operator in accordance with the information thereon. The top end 4a of the material 4 is disposed slightly upper than the top end 2a of the nozzle part 2 and therefore the error in the stage of liquid level detection owing to the influence of the liquid drop likely to stick always to the end 2a is prevented.
