Filed: 1980-02-05
Abstract: PURPOSE:To make electrolytic treatment work efficient in the production of electrolytic manganese dioxide by supplying the slurry in which the coarse particles in manganese oxide are settled and separated to an electrolytic cell. CONSTITUTION:Manganese oxide powder is supplied into a storage tank, in which a manganese sulfate soln. is stored. In this storage tank fine manganese oxide particles of about <=30mu suspend in the manganese sulfate soln. to form a slurry and the coarse particles settle in the bottom of the slurry storage tank. A prescribed amoung of this slurry is suitably taken out and is supplied into an electrolytic cell, where it is subjected to electrolysis. The electrolytic manganese dioxide deposited on an anode plate is stripped, and is neutralized and ground, whereby the product of electrolytic manganese dioxide is obtained. The coarse particles deposited in the storage tank are taken out and are ground, whereby they are reused as fine particles of <=40mu in about >=70%. Thereby, the slurray of the manganese oxide is uniformly suspended, and therefore electrolysis is accelerated and the step of taking out the precipitate is eliminated.

Title: Color image pick-up device
Inventor: FUJISAWA KATSUYA
IPC: H04N9/07
Filed: 1988-01-22
Abstract: PURPOSE:To use diffraction gratings to be inexpensive and abundant in mass producibility and to prevent a pseudo signal and a pseudo chrominance signal by using two diffraction gratings, causing a first diffraction grating at an image pick-up lens side to have a low-pass characteristic and causing a second diffraction grating at a solid image pick-up element side to have a work to delete the image of the diffraction grating with the first diffraction grating. CONSTITUTION:When the period of a first diffraction grating 31 at an image pick-up lens 2 side is made into a P1, the space frequency of the diffraction grating image generated by the first diffraction grating 31 is approximately 1/P1. For deleting the diffraction grating image, the sectional form of a second diffraction grating 32 may be arbitrary. For example, in the case of a sine wave form, when a distance from the second diffraction grating 32 to the image pick-up surface of a solid image pick-up element 1 is made into a (d) and the wavelength of an incident light to a color image pick-up device is made into a lambda, it is sufficient for a period P2 of the second diffraction grating 32 to be made into 2dlambda/P1. When the second diffraction grating 32 is arranged in a position close to the image pick-up surface 1 on conditions to make it smaller than the picture element size of the solid image pick-up element by the period P2 of the second diffraction grating 32, the image of the diffraction grating by the second diffraction grating 32 cannot be formed.
