Title: Manufacture of thermoplastic resin sheet
Inventor: SAKAMOTO JUN
IPC: B29C55/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To perform excellent productivity and quality by coating a surface of a charging roll and/or a surface of a cooling medium with liquid before a molten sheet is brought into contact with the roll. SOLUTION: Before a molten sheet is brought into contact with a charging roll, a surface of the roll and/or a surface of a cooling medium is coated with liquid, and the sheet is cast while holding the sheet between the roll and the medium. Then, an oil film is formed between the roll and/or the medium and the sheet. If the roll is coated with the liquid, a gap is eliminated between the roll and the sheet by the film, and the charge of the roll is uniformly given to the sheet. If the medium is coated with the liquid, close adhesive properties of the sheet with the medium are further enhanced. Here, as the coating liquid, water or the like is used. After the formed sheet is released from the roll or the medium, liquid droplets retained on the surfaces are removed.  Further, to uniformly coat the roll or the medium with the liquid as uniform droplets, humidified wet air is sprayed or the like.

Title: Photoelectric semi-conductor device
Inventor: MARUHASHI HIROSHI
IPC: H01L31/16
Filed: 1978-06-30
Abstract: PURPOSE: To improve position measuring accuracy and to prolong service life by taking out the  output from an electrode in a photoelectric conversion region in such a manner as to changed relative position between the photoelectric conversion region and a light radiation section on a semi- conductor base plate.  
     CONSTITUTION: A plate 11 turns to change position of a light radiation section 12 in relation to  a photoelectric conversion region 23; assuming that it is at point a now, if an opposite directional  resistance of a photodiode 23-2 lowered and impressed a positive potential onto an electrode 20,  it is electrified through the resistance 18. At this time, as a length 1 1  between the resistance 18's  end c and the light radiation position a is small and its resistance value is also small, a large output is obtained onto an electrode 21 provided at an end of the photoelectric conversion region  23. When the light radiation section 12 is at point b, while an opposite directional resistance of a  photodiode 23-n-1 decreases and electrified through the resistance 18, a length 1 2  between points  a and b of the resistance increases and the resistance value becomes large, and therefore, a small  output is obtained onto the electrode 21. At it is possible, in this way, to obtain an output without contact, its service life can be prolonged. And since the photoelectric conversion resion formed  on the semi-conductor base plate is especially uniform, a highly accurate output can be obtained.

Filed: 1979-06-27
Abstract: PURPOSE:To widen the input range of a bipolar A/D converter by converting the absolute value of an analog signal into a digital signal by a unipolar A/D converter and then by deciding the sign of the analog signal. CONSTITUTION:Analog signal 1 is input to absolute value circuit 2 to obtain its absolute value, which is converted into digital signals Dn-D1 by unipolar n-bit A/D converter 3 and they are input to one-side inputs of exclusive-OR circuit 6. At the same time, signal 1 is input to comparing circuit 4 whose reference voltage is zero to decide its polarity and information on it is sent to level converting circuit 5. When the information shows the positive, a signal of ''0'' is input from circuit 5 to the other-side input terminals of circuit 6 and when negative, a signal of ''1'' is also input. When signal 1 is positive, the digital converted signals of the absolute value appear at final digital outputs 8 as they are. When signal 1 is negative, adder circuit 7 obtains the complementary number of ''2'' of the digital converted signals of the absolute value as a digital converted signal of a negative value. Therefore, an input to the unipolar A/D converter can be utilized at a maximum.
