The present invention provides a semiconductor laser device including a heat sink having one main surface, an n-AlGaAs cladding layer disposed on the main surface of the heat sink, an AlGaAs active layer disposed on the n-AlGaAs cladding layer and a p-AlGaAs cladding layer disposed on the AlGaAs active layer. An effective refractive index and a thermal resistance between a main surface on the heat sink side, of the AlGaAs active layer and a main surface on the heat sink side, of the n-AlGaAs cladding layer are respectively set smaller than those between a main surface on the side opposite to the heat sink, of the AlGaAs active layer and a main surface on the side opposite to the heat sink, of the p-AlGaAs cladding layer.

An image forming device has plural photoreceptor drums on which a latent image is formed, wherein one of the photoreceptor drum is different diameter from the other photoreceptors. A belt in contact with the plural photoreceptor drums and plural transfer rollers press the photoreceptor drums from a side of the belt, the side being opposite to the side contacts with the photoreceptor, wherein a distance from a contact reference position. The contact reference position at which the photoreceptor contacts with the belt, to a pressed position of the transfer roller of a large-diameter photoreceptor drum is greater than that of a small-diameter photoreceptor drum.

An image forming apparatus including an image carrying belt which has volume resistance from 107 Ωcm to 1012 Ωcm and carries an image, a roller around which the image carrying belt is wound and which drives the image carrying belt, a transfer roller which includes a transfer material gripper which grips a transfer material which is disposed in a concaved portion of the transfer roller and which comes into pressing contact with the roller with the image carrying belt interposed therebetween so as to transfer the image carried by the image carrying belt to the transfer material, a bias applying unit which applies a transfer bias to the roller, and a ground unit which electrically grounds the transfer roller.

A transfer apparatus and an image forming apparatus are disclosed, in which a plurality of photosensitive drums corresponding to the respective colors are arranged along the outer peripheral surface of a transfer belt and a plurality of intermediate transfer rollers for applying a transfer field to the photosensitive drums are arranged offset downstream side from each of the photosensitive drums, respectively. In addition to that, the process, the intermediate transfer rollers are arranged in such positions that each of the nip width are increased progressively downstream side, respectively and each of the nip pressure are decreased progressively downstream side, respectively.

An image forming apparatus includes an image bearing member for carrying a toner image, a transferer supplied with a voltage to transfer a toner image from the member onto a recording material in a transfer portion, heaters with different heating conditions for heating the image transferred onto the material, a refeeder for refeeding the material to the transfer portion to transfer the image onto the material having the image fixed by the heater, a selector for selecting the glossiness of the image after fixing, a device for determining the heater to heat the image from the heaters in accordance with the glossiness selected by the selector, and a device for changing the voltage for transferring the image onto the refed material in accordance with the heater having heated the image on the material prior to the material being refed by the refeeder.

Force for biasing a roller member is changed according to the contact state of first and second plate-like bodies during the travel of the roller member. By that, the pressing force per unit area given from the second plate-like body to the first plate-like body during travel is suppressed. An object to be transferred is satisfactorily transferred despite a change in the contact state of the plate-like bodies during the travel of the roller member.

A solid-state image pickup apparatus selects, in a first image pickup circumstance in which dark current is liable to occur in vertical transfer paths of an array of photo-sensors, a first transfer mode in which the potential well capacity in the vertical transfer paths is relatively small, and, in a second image pickup circumstance in which the dark current is small in quantity, a second transfer mode which is greater in potential well capacity than the first transfer mode. As a positive voltage applied to the read-out gates of the photo-sensors, a first voltage mode indicating a relatively low positive voltage that suppresses impact ionization is set in the first image pickup circumstance, and, a second voltage mode indicating a positive voltage higher than in the first voltage mode is set in the second image pickup circumstance so as to cause the impact ionization.

In conjunction with a photomask blank comprising a transparent substrate, a pattern-forming film, and an etch mask film, a set of etching conditions for the pattern-forming film is evaluated by measuring a first etching clear time (C1) taken when the etch mask film is etched under the etching conditions to be applied to the pattern-forming film, measuring a second etching clear time (C2) taken when the pattern-forming film is etched under the etching conditions, and computing a ratio (C1 / C2) of the first to second etching clear time.

A unit for packing products, wherein a feed line, for supplying a strip of packing material, feeds the strip with a given movement to a cutting device for cutting the strip into a succession of sheets of packing material, and then to a feed station for feeding each sheet to a packing wheel moving with a further movement through the feed station; and wherein a compensating roller, having a compensating store, is interposed between the cutting device and the feed station.

The present invention relates to a process for the preparation of aqueous solutions of [1-13C]-hyperpolarized carboxylate containing molecules of diagnostic interest that comprises parahydrogenating with molecular parahydrogen unsaturated alkenyl or alkynyl esters of the concerned 13C-carboxylate molecules.

Force for biasing a roller member is changed according to the contact state of first and second plate-like bodies during the travel of the roller member. By that, the pressing force per unit area given from the second plate-like body to the first plate-like body during travel is suppressed. An object to be transferred is satisfactorily transferred despite a change in the contact state of the plate-like bodies during the travel of the roller member.

Provided are an ink jet image forming method and an ink jet image forming apparatus in which a complex elastic modulus (Pa) before an intermediate image comes into contact with a liquid absorbing member is 4.0 or more in the common logarithm, and a complex elastic modulus (Pa) before the intermediate image comes into contact with the recording medium is 7.0 or less in the common logarithm.

Provided is a gravure printing method by which high printing density and excellent highlight suitability are obtained, even if a gravure plate having high resolution and reduced thickness is used.
