IPC: C08G63/06
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To industrially advantageously obtain a polylactic acid having a high molecular weight, capable of resolving problems such as a limit of stirring viscosity, polymer attachment to a stirring wing and a lowering of molecular weight by re-heating after a solid state polymerization, by stirring the inside of a reaction tank with a twin-screw type stirrer, in a melt polymerization of a lactic acid monomer and a solid state polymerization of the obtained polylactic acid. SOLUTION: This production of polylactic acid is conducted by charging a lactic acid monomer in a reaction tank, refluxing water, a lactide, a polylactic acid oligomer and occasionally a solvent generated from the reaction tank and performing a melt polymerization while removing water to outside of the reaction system, then subjecting the resultant polylactic acid to a solid polymerization at a temperature lower than its melting point. At this time, the stirring in the reaction tank is performed by using a twin screw-type stirrer. Preferably, the stirrer is provided in a state that the two screws are engaged with each other.

Abstract: PURPOSE:To realize integration without short-circuit of wirig by adequately connecting circuit elements in the element region by burying signal lines in the element separating region while these are insulated from the substrate. CONSTITUTION:A groove 12 is formed in the desired shape with width of 1mum, depth of 1mum to the P type Si substrate 1 by the reactive ion etching in order to form the element region 2 and the P<+> type layer 4 is then formed by ion implantation. The entire part is covered with the thermal oxide films 3, 8 and the signal line 5 consisting of conductive material such as MoSi2 is buried in the groove 12 by sputtering. Moreover, a thermal oxide film 8 is caused to grow. In this case, since the signal line 5 is porous, the thick film 8 is formed on the signal line. Next, an impurity layer 7 for circuit element to be formed to the element region 6 is formed and the Al wiring 11 which connects the layer 7 and signal line 5 is formed on the insulating layer 8. Owing to such structure, a number of wirings of substrate surface is reduced and thereby highly reliable device resulting in less short-circuit troubles can be obtained.

Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To decrease the number of detection switches and to reduce the facility cost and construction cost while maintaining the reliability of operations by stopping main equipment when at least two switches among a signal monitor switch and two detection switches decide that the main equipment should be stopped. SOLUTION: The signal monitor switch 24 and detection switches 11 and 12 decide whether or not the main equipment 2 should be stopped according to the analog signal 21a outputted by a transmitter 21 and detected numerals and the main equipment 2 is not stopped when there is no abnormality. Here, even if one of the signal monitor 24 and detection switches 11 and 12 malfunctions to decide abnormality although the actually detected numerals are not abnormal, a command of stopping the main equipment 2 is not outputted from a 2-out-of-3-line circuit 13 as long as the remaining two switches are operating normally. Consequently, the main equipment is never stopped owing to the malfunction of one switch.

Title: Pockels cell driving circuit
Inventor: SUZUKI YOSHIKAZU
IPC: H01S3/107
Filed: 1990-03-30
Abstract: PURPOSE:To reduce the deterioration of a Pockels cell by providing a passive element between the connection part between the Pockels cell and a capacitor and the ground so as to prevent a potential difference from being generated across the Pockels cell in the state wherein a switching element is open. CONSTITUTION:When the switching element 13 is open, a capacitor 14 is charged with the output voltage of a high voltage power source 11 through a charging resistance 12. At this time, the voltage applied across the Pockels cell 15 is 0V because it is small enough to ignore the inductance of an inductor 16 provided in parallel, so that no potential difference is generated. Then when the element 13 is closed, a current corresponding to charges accumulated in the capacitor 14 flows to the ground through the element 13, so the terminal voltage of the capacitor 14 on the side of the cell 15 becomes nearly equal to the output voltage of the power source 11 and is only inverted in polarity. Further, the terminal polarity of the cell 15 on the side of the capacitor 14 is the polarity obtained further inverting the polarity of the terminal voltage of the capacitor 14 and its level is determined according to the electrostatic capacity of the capacitor 14 and cell 15.

IPC: B65H1/26
Filed: 1989-04-04
Abstract: PURPOSE:To make the feeling of resistance which is given at the time of inserting a cassette little by sandwiching and guiding the cassette to a film exchanging position by means of guiding members after inserting the cassette. CONSTITUTION:When the cassette 1 is inserted from a cassette insertion port, a microswitch MS1 is turned on and a belt motor is driven so as to normally rotate a belt 3. When the cassette 1 is conveyed in by the belt 3 and reaches the film exchanging position, a microswitch MS3 is turned on and the belt motor is stopped. Meanwhile, by turning on the microswitch MS1, a guide motor 21 is driven and the guides 11 and 12 move in a closing direction, then they guide the cassette 1 by sandwiching the cassette 1 which is being conveyed from both sides. After sandwiching the cassette 1 by the guides 11 and 12, bars 15 and 16 get still at that position. After a driving bar 18 separates from a coupling shaft 17 and moves downward, the cassette 1 is conveyed in regulating the width direction thereof with the aid of the guides 11 and 12. Thus, the feeling of resistance which is given at the time of inserting the cassette is made little.

Title: Data waveform shaping circuit
Inventor: OINUMA AKIRA
IPC: H04L25/40
Filed: 1982-05-18
Abstract: PURPOSE:To perform data waveform shaping with an optimum slice level, by comaring error data of plural periods with each other, and inverting the changing direction of the slice level when the error data increase. CONSTITUTION:An up-down counter 15 starts from an up-mode, and a slice level 3 rises up one step synchronously with the pulse of a clock signal 14. As a result, error factor of data increases to obtain A>B at a magnitude comparator 12, and then an FF13 is inverted. This drops the level 3 by a step, and therefore the error factor is reduced. Then the level 3 lowers by a step with the next clock pulse. In this case, if the error factor of data increases, A>B is obtained again to reset an up-mode. Such a cycle is repeated to make the level 3 follow on the basis of the optimum level with which the data errors are minimum. Thus it is possible to perform data waveform shaping with an optimum slice level.

Abstract: PURPOSE: To enable a person not skilled in singing to correctly sing accompanied with accompaniment, by displaying the timing of song start at the introduction, in singing with the reproduction of an accompaniment tape.  
     CONSTITUTION: In the accompaniment tape 1, the introduction recording part B is normally recorded in greater level than the accompaniment recording part, the DC average level of the output signal of the amplifier 16, the reproducing signal obtained from the magnetic head 4, is greater in reproducing the introduction recording part B than in reproducing the accompaniment recording part C. When the signal level difference like this is used, no detection signal is outputted from the level detector when the introduction is reproduced, but the detection signal is outputted from the level detector 17 when the introduction is finished into the accompaniment. Thus, the drive circuit 18 outputs the drive signal to the song start timing display means 15.
