Title: Fm stereo demodulator
Inventor: ISHIDA KOUJI
IPC: H04H40/54
Filed: 1982-09-13
Abstract: PURPOSE:To keep the separation in the optimum state, by detecting the amplitude of a rectangular wave pulse or a sine wave subcarrier, and comparing the detection output with the reference voltage to control the amplitude of the sine wave subcarrier. CONSTITUTION:A P-P detecting circuit having smaller variation is omitted between the amplitude variation of a rectangular wave pulse serving as the output of an FM wave detector and that of a sine wave subcarrier of 38KHz. Instead a reference is fed to a comparator. When the amplitude variation of the rectangular wave pulse of FM wave detection output is smaller than that of the 38KHz sine wave subcarrier, the reference voltage Vref is applied to the positive side of a comparator 3 instead of detection of the P-P value of the rectangular wave detection. Then the P-P value of the 38KHz sine wave subcarrier, i.e., the output of a P-P detecting circuit 6 is applied to the negative side. The output of the comparator 3 is applied to a control terminal of a VCA7 to form a so-called AGC loop. Thus the amplitude is kept at a constant level for the 38KHz sine wave subcarrier, i.e., the output voltage of the VCA7.

Abstract: PURPOSE:To detect the focusing state of an object image, by selecting plural photodetectors in a photodetector array which receives a part of the object image and operating outputs of them on the basis of a prescribed evaluation function. CONSTITUTION:The luminous flux from a photographic lens 21 is led to photodetector  arrays 25 and 26 to form a blurred image corresponding to the quantity of defocus  from the lens 21. The paraxial luminous flux transmitted through a semitransparent  mirror 23 is made incident to a photodetecting element array 28 to focus always the almost same image in the focusing state approximately. Exposure of photodetecting  element arrays 25, 26, and 28 is started through exposure time controlling circuits 32  and 25 by a central processing unit 31, and their outputs are held in circuits 33, 34, and  36 and are subjected to A/D conversion in an A/D converter 37 and are supplied to an  operating circuit 38. Adjacent elements having the largest and the next largest differential A/D conversion values are detected in the array 28. A/D conversion outputs of  photodetecting elements of arrays 25 and 26 corresponding to these detected photodetecting elements are operated on a basis of an evaluation function, and the lens 21 is focused on the basis of the discrimination result of the focusing state due to the device  31.

Abstract: PURPOSE:To prevent melting of the base metal of each discharge lamp even if their filaments blow off to cause flowing of a short-circuiting current in an evaporation film. CONSTITUTION:When discharge lamps FL1, FL2 go into their final period of lifetime to cause a rise of the voltage and generate short-circuiting by an evaporation film of flares, a zenor diode ZD1 is turned on. Light emitting diodes LED1, LED2, LED3, LED4, LED5 are made to emit light, and photo-transistors PTr1, PTr3, PTr4 are turned on so that short-circuiting is generated between filaments FL1a and FL2b while the current in the evaporation film is bypassed, and thereby current flowing to the evaporation film is prevented.

Title: Controlling method for dwelling in injection molder
Inventor: SUZUKI KENJI
IPC: B29C45/77
Filed: 1986-07-10
Abstract: PURPOSE:To make it possible to apply a dwell pressure, which is scrupulously controlled in response to the cooling and setting state of the resin in a mold cavity, and consequently and especially improve the quality of a precision molded item by a method wherein the magnitude of the dwell pressure is controlled in response to the movement of an injection screw during dwell process. CONSTITUTION:When a screw 3 moves by a distance, which is obtained by dividing the predetermined movement (l) of the screw into (n) equal-length portions or mun, during dwell process, as the shrinkage of the resin in a mold cavity 5 due to cooling proceeds, the detected value of the positional detector 10 of the screw 3 coincides with the set point of an interval setter 12 to change over the dwell pressure. As a result, a switch 11 is put into acutuation so that, for example, the second relay coil 132 is demagnetized and at the same time the third relay coil 133 is excited so as to control the magnitude of the dwell pressure to P3. In such a manner as just mentioned above, the dwell pressure is controlled one after another to the preset value. Finally, when the movement of the screw 3 since the start of dwell process reaches the predetermined movement (l), the dwell pressure is changed over to zero so as to complete the dwell process.
