Title: Cold insulation storage
Inventor: HATAKEYAMA GIICHI
IPC: F25D19/00
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a cold insulation storage which is excellent in heat insulation property between a machine room and a goods storage room. SOLUTION: Since an accumulator is installed through a vinyl sheet 2h low in heat conductivity, without installing an accumulator through a metallic (material low in heat conductivity) mounting board as in the past, in the recess 2f of a heat insulating box, there is little influence of cold within the heat insulating box, this cold insulation storage can suppress the occurrence of dew condensation in the recess 2f. Moreover, even if dew condensation should occur in the recess 2f, the dew-condensed water is never absorbed by the heat insulating material 2c because the vinyl sheet 2h is watertight, consequently the heat insulating function of the heat insulating box 2 never depresses.

Title: Additive information transmission system for high-definition television system
Inventor: YAMASHITA AKIHIKO
IPC: H04N7/085
Filed: 1987-10-07
Abstract: PURPOSE:To add information data with many bits to a high-definition television signal and to transmit them by switching the pattern of a horizontal signal according to the logical value of the respective bits of the additive information data, and transmitting the information data at every bit into one horizontal period. CONSTITUTION:The high-definition television(TV) signal inputted to a terminal 1 is the signal before the insertion of the horizontal synchronizing signal. First and second horizontal synchronization generating circuits 2 and 3 respectively generate first and second horizontal synchronizing signals (a) and (b) by a timing pulse TP1 corresponding to the horizontal synchronizing signal inserting period of the high-definition TV signal. Since one of the first and second horizontal synchronizing signal (a) or (b) is successively selected and transmitted according to each bit of the information data to be added, the data of approximately 1k bit per frame can be transmitted. Thus, even for the high-definition TV signal, which uses a vertical blanking period for the transmission of a sound signal, the information data with many bits can be multiplexed and transmitted.

Inventor: SATO SHOGO
IPC: G03G15/08
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of satisfactorily reproducing fine lines and isolated dots even if a positively charged photosensitive drum and positively charged toners are used. SOLUTION: Impression development is executed by using the positively charged photosensitive drum 20 and a developer having the styrene acryl toners and at least a charge control agent, such as nigrosine or triphenyl methane, and pressing a developing roller 56 at least the surface layer of which is formed of a member having ion conductivity, such as lithium chlorate, to the photoreceptor drum 20. Consequently, the electrostatic charge quantity of the toners 53 past the nip part of the photoreceptor drum 20 and the developing roller 56 is larger than the electrostatic charge quantity of the toners 53 on the developing roller 56 before the passage through the nip part and further the excessive lowering of the potential of solid white parts is averted.

Title: Toner concentration controller for copying machine
Inventor: ASANUMA MASAHITO
IPC: G03G15/08
Filed: 1985-11-12
Abstract: PURPOSE:To stably control toner concentration by calculating the toner consumption in accordance with the reflectivity of a transfer paper and replenishing the quantity of toner corresponding to the consumption not to vary the toner concentration by the physical property change of a developer. CONSTITUTION:Plural reflection type photo sensors 7 are arranged in the direction orthogonal to the feeding direction of a transfer paper 6. These photo sensors 7 detect the presence/absence and the density of the toner transferred onto the transfer paper 6 in accordance with the reflectivity, and plural photo sensors 7 scan the transfer paper 6 relatively in accordance with feeding of the transfer paper 6 to detect an average toner concentration. A control circuit integrates the average toner concentration detected by photo sensors 7; and when is reaches a certain value, a toner motor 3 is driven to replenish a certain quantity of the toner. Thus, the quantity of the toner corresponding to the consumption is replenished if proper relations are set between the reference level of a comparator 12 and the time when the toner motor 3 is operated by a timer 14.

Title: Multicolor discriminating color copying method and its device
Inventor: KOIZUMI YUTAKA
IPC: G03G15/01
Filed: 1986-10-28
Abstract: PURPOSE:To attain multicolor discriminating expression only by two-color toner by dividing visual rays of light into two components, i.e. a long wavelength side and a short wavelength side, forming electrostatic latent images by the two divided rays of light and developing the latent images by color toner having complementary color relation respectively to the two divided rays of light. CONSTITUTION:Original illuminating light is divided into two components, i.e. the short wavelength side (e.g. alpha color) and the long wavelength side (e.g. beta color) by fixing 550nm as a boundary, electrostatic latent images are formed by respective light beams and developed with toners having complementary color relation to these divided light beams and two color toner images are superposed and transferred to one transfer paper to obtain a multicolor copy obtained by superposing the alpha color image to the beta color image. In case of using illuminating light (additive color mixture), white can be obtained by mixing the alpha color with the betacolor, and in case of using toner or the like (substractive color mixture), black or a color close to black can be mixed by superposing the alpha color to the beta color. Since the optical strength of the color component is different from that of the color component in each color original, a potential difference may be generated in electrostatic latent images on a photosensitive drum. Thereby, colors can be discriminatively expressed as the combinations of density differences of alpha and beta color toner images.
