Title: Image forming device
Inventor: KAGIURA KAZUO
IPC: F16H31/00
Filed: 1988-02-29
Abstract: PURPOSE:To control the irregularities in an image by supporting an image carrier driving material and developing driving material with a shaft which receives a driving power from a power source, with play in the direction of the rotation, which absorbs the rotation irregularities and load changes. CONSTITUTION:A gear 22 is connected to a shaft 17 so that there is play in the direction of the rotation. That is, a pin 34 which is inserted into the axis 17 in the direction of the radius, is fitted into a long groove 35 provided on a gear 22. Further, the width of the long groove 35, in the rotation direction of the gear, is wider than the width of the pin 34, the gear 22 is connected to the shaft 17 with play in the direction of the rotation, and when the shaft 17 rotates, the pin 34 makes the gear 22 rotate by pushing the side of the groove 35. Because the gear 22 is fixed onto 17 with play in the direction of rotation, even when rotation irregularities arise in a driving power transmitting path, which transmits the driving power to the axis 17, the rotation irregularities can be controlled from being transmitted to a developing sleeve 12 or a drum 1. Thus irregularities in the image can be controlled from arising.

IPC: G02C7/06
Filed: 1988-02-29
Abstract: PURPOSE:To make the connection between the section for long distance and an intermediate section while the section F for long distance is widely secured by forming the section for long distance in such a way that the shape of the longitudinal section of the refracting surface increases as going farther from the main meridian curve along the cross-sectional curve at the upper part and the lower part is formed in the opposite way, and then, the cross-sectional shape is fixed at the central part. CONSTITUTION:The section F for long distance is formed in such a way that the shape of the longitudinal section of the refracting surface at the upper part increases in the radius of curvature as going farther from the intersection with the main meridian curve MM' and the shape of the longitudinal section of the refracting surface of the lower part decreases as going farther from the intersection with the main meridian curve MM'. At the central part of the section F, the radius of curvature is fixed on the longitudinal section of the refracting surface. Therefore, the density of the astigmatic difference of the surface refracting power is lowered and the gradient of the astigmatic difference becomes gentler. In addition deformation and oscillation of images are also reduced.

CONSTITUTION:Corrugations 5 are pressed on the entire surfaces of the side plates 3' and bottom plates 3'' of an inner vessel 3 of membrane so that the corrugations extend vertically and horizontally on flat plate portions 6. The inner vessel 3 of  membrane is secured on an outer vessel 2 by anchros 8 on the blocking parts of the corrugations 5.

Title: Selective incoming call system
Inventor: TANAKA YUKIO
IPC: H04M11/00
Filed: 1985-03-11
Abstract: PURPOSE:To decrease charging during call being a problem in conventional selective incoming calls and to prevent the generation of talking disable state by operating a selective incoming call function only at a preset time zone. CONSTITUTION:Every time an incoming call comes to a subscriber line 7, a control circuit 10 started by a call signal receiver 1 compares the time of a clock circuit 8 with the time zone read from a memory 9 and when the information is coincident, that is, when a present time is included in the set time band, the selective incoming device applies automatic response. On the other hand, when the time zone of the memory 9 and the value of the clock circuit 8 are dissident in the control circuit 10, contacts (a, b) are closed and a contact (d) is connected to a telephone set terminal device being the No.1 terminal device. Thus, a loop is generated by a loop forming circuit 2 without selective incoming to reply a calling terminal device, and the caller is connected immediately to the telephone set terminal device, then the same operation to the incoming call to the normal telephone set is attained.

Abstract: PURPOSE:To allow the commencement of product design while determining the detail parts of film forming conditions so that the procedures from the design to the production is drastically shortened by measuring the refractive index and coefft. of light absorption of two dielectric films and determining the max. value (nmax) of the refractive index that the dielectric film of the nearly zero coefft. of light absorption can take from the linear approximation using these two values. CONSTITUTION:The two dielectric films 2 which vary in the film forming conditions and are not zero in the coefft. of light absorption are formed on a substrate 1. The refractive indices and coeffts. of light absorption of the two dielectric films 2 are measured and the max. value (nmax) of the refractive index that the dielectric film 2 of the nearly zero coefft. of light absorption can take is determined from the linear approximation using these two values. The max. value (nmax) of the refractive index that the dielectric film of the zero coefft. of light absorption can take can be estimated in a short period of time in this way and, therefore, not only the determination of the film forming conditions is easy but also the refractive index can be first determined in an early state and the early commencement of the product design is possible. The procedures from the design up to the production are thus drastically shortened.
