Title: Method for making parison in blow molding
Inventor: KONISHI TEIICHI
IPC: B29L22/00
Filed: 1987-02-27
Abstract: PURPOSE:To eliminate the ununiformity of temperature in a parison and consequently reduce the fluctuation in the wall thickness during blow molding by a method wherein pre-blow molding is done before the blow molding by vertically shifting a die head in a mold and pinching the parison. CONSTITUTION:A die head 1 is lowered from the upper opening 2a of an open mold 2 through a hollow chamber 2c in the mold 2 down to below the lower opening 2b so as to start the extrusion of a parison (b). The tip (c) of the parison (b) is pinched with parison pinchers 4 and, after that, gas is poured in the parison (b). At the same time, the die head is raised. When the die head 1 reaches above the upper opening 2a of the mold 2, the open mold 2 is closed and the final blow molding is done in order to complete the molding. Since the pre-blowing can be done before the blow molding while the parison is kept on being extruded, the parison is expanded under the same temperature over the whole region of the parison, resulting in allowing to realize the uniform final blow molding.

Abstract: PURPOSE: To decontaminate a drainage by adding borohydride BH4 ions to a drainage and separating a precipitation containing ruthenium from a liquid drainage thereby producing the precipitation containing ruthenium in the liquid drainage. CONSTITUTION: A drainage is subjected, at first, to preconditioning of pH to 0.8-1.2 and then added with a soda water of 1N containing about 5g/l of sodium borohydride.

By applying voltage, the filament 2b is welded at a proper portion to be melt, and is thus connected in an optimal welding condition.

Title: Detector for breadth and breadthwise displacement of sheet blank
Inventor: KUBOTA AKIRA
IPC: G01B7/00
Filed: 1979-04-14
Abstract: PURPOSE: To enable accurate detection regardless of surrounding environments and object of detection, by opposedly providing displacement detecting parts having magnetic sensors at both sides of a sheet blank between opposedly provided magnetic field generating parts, and detecting the displacement by means of the deviation output.  
     CONSTITUTION: Excitation coils 1, 2 and a detecting coil 5 are housed in outer cases 7, 8, which are integrated by means of a joining member 9. The space between the excitation coil 1 and the detecting coil 5 should be a vacant area for feeding sheet blanks. That is, while sheet blank not illustrated is not supplied in the detecting space, the magnetic fields generated between the excitation coils 1, 2 are balanced, and the output of the detecting coil 5 is zero. When the sheet blank enters the detecting space, the magnetic flux generated from the excitation coil 1 is cut off. Since the magnetic fields are alternating magnetic fields, an output appears in the detecting coil 5. As a result, accurate detection is possible regardless of the environments and other conditions.

Title: Generator for low-frequency sine waveform controlling voltage
Inventor: NANUN TOSHIO
IPC: H03B28/00
Filed: 1979-04-13
Abstract: PURPOSE:To obtain easily an arbitrary low-frequency sine wave by using the rotation frequency of a motor as an oscillation source to take out the electric signal of the sine waveform by a photoelectric conversion element. CONSTITUTION:When an arbitrary voltage is applied to terminal 1, motor 3 is rotated with the number of rotations corresponding to the applied voltage by speed control circuit 2. Disc 5 and light source 4 fixed to the shaft of motor 3 are rotated, and rotation of the irradiated point is obtained on the light receiving face of photoelectric conversion position detector 6. When a fixed light quantity is irradiated in the light receiving face of detector 6, currents are flowed to output terminals 7 and 8, and the current value difference between two terminals is proportional to the distance from the axis through the center of the light receiving face of the irradiated point. When this current value difference is amplified by differential amplifier 9 to take out a voltage at output terminal 10, a sine waveform of the same frequency as rotation of light source 4 appears at terminal 10, so that a low- frequency sine wave output according to the magnitude of the input voltage of terminal 1 can be obtained.

Title: Image forming device
Inventor: KOBAYASHI KATSUAKI
IPC: G03G15/00
Filed: 1988-02-29
Abstract: PURPOSE:To prevent a charge-up of developer and to restrain deterioration in image density by forming a dummy latent image on the surface of an image carrier in a non-image area part which arises on the surface of the image carrier and also developing this dummy latent image by a developing means. CONSTITUTION:The dummy latent image is formed on the non-image area and it consumes developer on the side of the developing means which corresponds to the non-image area on the surface of the image carrier. The width of the revoluting direction of the image carrier having the dummy latent image is arbitrarily changed according to the constitution of a developer device, the developer employed by the developing device and its surroundings. Thus, even in case of a part corresponding to the non-image area, the developer of that part in the developing device is consumed by developing the dummy latent image in that part; therefore deterioration in image density which is caused by the charge-up of the developer in that part, can be eliminated.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To improve with a great stride the calculation ability of a digital computer by acquiring a stable multivalue larger than the number of elements which constitute a cell. SOLUTION: The orbit stability of a nonlinear circuit is guaranteed by executing nonlinear quantization so that a transmission characteristic is made to be linear. In the cell of an integrated circuit, and input/output transmission characteristic of a chaos generation one-dimensional mapping circuit of a nonlinear function is rebundled to be nonlinear and a linearized transmission characteristic is obtained. Then, an orbit is stabilized by uniformizing the distribution of inner states per quantum for obtaining a multilevel. The chaos generation one-dimensional mapping circuit can be constituted of six MOS transistors (three PMOS and three NMOS). A nonlinear A/D converter and a D/A converter are connected to the chaos generation one-dimensional mapping circuit so that they become a loop, and the multivalue is acquired from the output of the A/D converter.  The acquired multivalue is made into a digital code and captured into the memory of a general-purpose computer.
