Title: Printing status checking device
Inventor: MITSUI SEIJI
IPC: G01N21/88
Filed: 1985-02-27
Abstract: PURPOSE:To enable automatic setting of a reference value for checking and make the checking effective by providing a signal processing circuit to switch check mode and learning mode. CONSTITUTION:A signal processing circuit 10 switches a learning mode by which a reference value for deciding the qualification of printing and tolerance can be set, and a mode by which checking is performed according to an already established reference. The check mode enables comparison of the calculated position of each color mark with an established reference value to calculate an error. Then if this error falls within a tolerable range, printing is decided as 'qualified', and if the error remains outside the range, printing is decided as 'unqualified'. Accordingly, a marker paper is inserted and an alarm output as procedures to deal with such defects. The learning mode prepares plural pieces of printed matter decided as 'qualified' by visual check beforehand, calculates the position of color mark on each printed matter, and seeks a mean value of these data as a reference value. A tolerable error is preset to meet the ranking of printing precision, and a tolerable error to the mean value is automatically set.

Title: Joint for vessel of thermoplastic resin
Inventor: YOKOYAMA TAKAHITO
IPC: F16L5/02
Filed: 1994-03-09
Abstract: PURPOSE:To generate fusion attachment with good tight attaching performance without provision of a small wall thickness part in the wall of a vessel by forming the contacting surface of a flange part in a curved surface alongside the wall of the vessel, wherein the flange part is contacted with the wall part around a through hole and fusion attached with heat. CONSTITUTION:The wall 10 of a vessel is formed from a thermoplastic resin such as polyethylene, and a through hole 11 is provided in a part where a joint 21 is fixed. The wall 10 is part of a circular polyurethane structure formed in a curved surface, and accordingly the part 11a around the through hole 11 is alike formed in a circular curved surface. The contacting surface 23a of a melting flange 23 of the joint 21 is made in a curved surface alongside the peripheral part 11a of the through hole 11, and it is possible to attach the joint 21 to the wall 10 with a high fusion attach strength. Because no pedestal is formed in the peripheral part of the through hole 11, the thickness of the wall 10 around the through hole 11 is uniform, and there is no risk that a small wall thickness part is produced where the mechanical strength is insufficient.

Title: Spectroscope with uniform intensity of light
Inventor: YAMADA MASAHIRO
IPC: G01N21/25
Filed: 1985-02-27
Abstract: PURPOSE:To output a monochromatic light fast and in uniformity at a high accuracy, by controlling the intensity of light at a high speed and electrically with a light intensity modulator. CONSTITUTION:Light from a light source 1 is spectrally analyzed with a light wavelength selecting section 2. The resulting light is modulated 4 in the intensity of light to obtain a light output 11 through a halfmirror 5. At the same time, a part of the monochromatic light modulated in the intensity from the halfmirror 5 is fed to a photodetector 6 and the potential of the photodetector 6 generated by the light is amplified with an amplifier 7 and the difference between the output potential thereof and the potential of a wavelength-wise specified potential generator 8 is detected with a differential amplifier 9. Then, the output of the amplifier 9 is inputted into an electric control section 10 to control the intensity of light by applying a negative feedback to the modulator 4 so that the difference between the potential of the photodetector 6 and the specified potential of the generator 8 will be zero. This can yield a monochromatic light output 11 with the uniform intensity of light at a high speed close to the operating frequency limit of a superhigh speed shutter and with a highly improved accuracy.
