Title: Glassy carbon-coated graphite component for producing silicon crystal and production thereof
Inventor: AAUIN CHIYAARUZU RUISU
IPC: C30B29/06
Filed: 1992-08-28
Abstract: PURPOSE: To obtain substantially carbon-free silicon crystal by using a graphite crucible having the outer layer of glassy carbon formed from a thermoset organic resin.  
     CONSTITUTION: As for the thermoset resin, for example, a phenol resin or furan polymer showing carbon yield more than about 20% and viscosity of about 200 to 300 cps is used. The graphite crucible is immersed in about 50% furfural solution of this resin and heated later at a temperature of 100° to 300°C over a period of 1 to 10 hours. By repeating this operation, the uniformity of deposited layers is improved. Next, a coated component is further heated to a temperature of 500° to 2,000°C and the resin is transformed to glassy carbon. The thickness of this carbon layer is 0.5 to 25 mils. This product is further treated at a temperature of 1,400°C to 1,800°C in a halogen gas atmosphere so as to be further purified. By using this crucible for producing the silicon crystal through the Czochralski process, the substantially carbon-free silicon crystal can be obtained.

Title: Web handling control method
Inventor: IMOTO KENICHI
IPC: B65H26/06
Filed: 1989-09-06
Abstract: PURPOSE:To lessen the shock to be given when a web takeup is ended, by determining the decelerative region starting point of a speed reference pattern through specified calculations, and decelerating the web handling speed as the running speed of web at a specified deceleration rate when the web takeup is finished till the mentioned starting point. CONSTITUTION:The length l of a web 2 to be taken up on a takeup reel 5 during a period corresponding to the deceleration region is determined from the formula l=Vc<2>/2a, where Vc is web running speed in steady region and a is constant deceleration rate in deceleration region. When the taken-up length lx of the web 2 becomes equal to the difference of l from a specific amount L, the running speed is decelerated at the deceleration rate a. This accomplishes taking-up of web in the specified length on the takeup reel 5 at the very point of time when the web running speed has become just zero.

Title: Voice coding/decoding device and voice decoding device
Inventor: MORIO TOMOKAZU
IPC: G10L25/90
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve the pitch predicting precision by shortening the renewal period of pitch length compared with the renewal period of pitch predicting factor. SOLUTION: Frequency dividers 102, 107 are newly added to give the renewal period of pitch length shorter than that of pitch predicting factor. Though the instructions on analysis processing of pitch predicting factor are given to a pitch prediction analysing filter and a pitch prediction synthesizing filter with the same period as the past one, the instructions on the analysis processing of pitch length are given with a frequency faster than that in the analysis processing of the pitch predicting factor by frequency dividers 102, 107. By using these means, the renewal period of pitch length is shortened compared with the renewal period of the pitch predicting factor. Accordingly, the pitch predicting precision is improved in the voice coding/decoding device which conducts pitch prediction to plural sample length units.

CONSTITUTION:Detecting values from a key switch 1d, an airflow meter 4, an in-cylinder pressure sensor 11, and a crank angle sensor 14 are inputted to a control means 16. The control means 16 calculates on average effective pressure shown in Fig per one cycle based on outputs from the in-cylinder pressure sensor 11 and the crank angle sensor 14, Even when the key switch 1d is turned ON and the effective pressure shown in Fig is below or exceeds a reference value, when the state is not continued during a given cycle, an air-fuel ratio is enriched by an equivalent in order to promote the starting. When a state in which the average effective pressure shown in Fig exceeds a given value is continued during a given cycle or more, it is decided that initial explosion enters, an air-fuel ratio is further leaned than that during the starting, and the feed of fuel required for warming up is performed.

Title: Abnormal load detecting method for servo gun shaft and its device
Inventor: KATO TETSURO
IPC: B23K11/31
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To quickly detect the fusion or the like between a welding tip and the object to be welded before the movement of a robot without giving a bad influence to the object to be welded. SOLUTION: A load acting on a servomoter driving the welding tip of a welding gun is detected with an observer (S8). An abnormal load detection judging whether a detected estimated disturbance load exceeds or not the level of a reference value β is executed (S10, S11), an abnormal load signal is outputted in the case of exceeding (S12). However, until the estimated disturbance load becomes a set value α or below from the starting of welding operation (FLG1=1) with the opening operation of the welding gun (S2, S3, S5, S6, S7), the pressing force for welding is detected as a positive estimated disturbance load, whether the estimated disturbance load exceeds the level of the reference value +β is not judged in order not to detect as the abnormal load (S9, S10).  A negative estimated disturbance load is obtained at the time of welding, since this comes to exceed -β (S11), the abnormal load signal is outputted (S12).
