摘要:
The invention is intended to reduce the number of parts constituting an image capturing system using a solid-state image sensor and reduce the size and cost of a mobile electronic appliance having camera functionality. An analog front end circuit for an image capturing system, which samples pixel readout signals input from a solid-state image sensor, amplifies the sampled signals up to a predetermined level, and converts the amplified signals into digital signals, is formed, together with a DSP for digital image processing and a CPU responsible for arithmetic processing and control for camera functionality such as auto focusing and register setting, in a semiconductor integrated circuit on a single semiconductor chip.

A level shift circuit having a latch function includes a precharging PMOS transistor MP1 which is turned on in a precharge period to interrupt a through current of an input stage, an NMOS transistor MN1 which inputs data and performs discharging in a data input period, and a transistor MP2 for holding data after level shifting. Thus, each of the transistors can have a minimum configuration. Since the level shift circuit has a latch function, it is possible to omit a circuit for latching input data, thereby reducing a circuit area.

An image forming apparatus includes an image bearing member, a flexible changing member and a developing device. When a first area to be an image forming area of the image bearing member, is present in a nip portion, a superimposed voltage resulting from a direct current voltage and an alternating voltage having a peak to peak voltage smaller than an alternating voltage applied when a charging potential of the image bearing member is converged is applied to the charging member. When a part of a second area to be a non-image area of the image bearing member exists in the nip portion, a direct current voltage without an alternating voltage is applied to the charging member.

A cleaning apparatus for use in an image forming apparatus removes toner, including spherical toner particles, from an image bearing member for bearing a toner image for use in an image forming apparatus. The toner to be removed is a one-component toner having a shape coefficient SF1 of 100 to 120. The apparatus has blade-shaped elastic member rubbing a surface of the image bearing member for removing the toner and is urged against a surface of the image bearing member with a line pressure of 55 to 95 g·f/cm. The elastic blade is formed so that a thickness of a portion, supported by a support member, of the elastic blade is larger than a thickness of a free end of the elastic blade.

An aliphatic polyester resin having a .lambda. value representing the magnitude of non-linearity of elongational viscosity of 1.5 to 8.0, said .lambda. value being defined by the following formula (1): .lambda.=.lambda..sub.1 /.lambda..sub.0 ( 1) wherein .lambda..sub.0 denotes the elongational viscosity at the transition point and .lambda..sub.1 denotes the elongational viscosity when strain become twice that of a transition point, said transition point meaning a point between a linear region, i.e., the infinitesimal-deformation region, and a non-linear region, i.e., the large-deformation region. According to the present invention, an aliphatic polyester resin having excellent formability and forming stability as well as good biodegradability is provided.

A space modulation device 10 displays an image for right eye and an image for left eye. An observer image display device 12 displays an image of a half surface of an observer's face obtained by an imaging device 14 and a negative-positive reversed image of the image of the half surface of the face. A lens 11 allows the image for right eye or the image for left eye to be observed to the right eye or the left eye of the observer using the image of the half surface or the negative-positive reversed image thereof as an illumination for the spatial modulation device 10 from the back thereof.
摘要:
A culture equipment for bio-organisms such as animal cells and plant cells, having substratum and a circulation-inducing chamber, accommodating the material for substratum made of fibrous, or porous, or layered substance, such as of ceramics, plastics, resin or skin having a number of spaces in the substratum for adhesion or immobilization of microorganisms and medium permeation in the lid-containing vessel, and circulating the culture medium by a rotater device in the circulation-generating room is described in the present invention. The gas exchange of the culture medium is performed in the upper part of the vessel in the course of circulation. Growth and maintenance of micro-organism cells in mass and at a high density can be attained.
