Inventor: MORI KENJI
IPC: C07D303/04
Filed: 1991-09-12
Abstract: PURPOSE:To selectively obtain the required Z-isomer in a short process and provide a sex pheromone of stinkbugs belonging to the Nezara and Acrosternum species from inexpensive and readily available raw materials by reacting a specific epoxyketone with a specified phoshonium salt in the presence of a base. CONSTITUTION:An epoxyketone expressed by formula I, i.e., cis-,trans-1- acetyl-3,4-epoxy-4-methylcyclohexane is reacted with a phosphonium salt [e.g. triphenyl (4-methyl-3-pentenyl)phosphonium iodide] expressed by formula II (Ph is phenyl; X is halogen) in the presence of a base (e.g. methyl-lithium or sodium hydride) to afford a sex pheromone of stinkbugs belonging to the Nezara and Acrosternum species expressed by formula III, i.e., (Z)-cis,trans-2-(3',4'- epoxy-4'-methylcyclohexyl)-6-methylhepta-2,5-diene. The epoxyketone expressed by formula I is obtained by reacting a compound expressed by formula IV with m-chloroperbenzoic acid.

Abstract: PURPOSE:To enhance the quality of a color image by making it possible to record the color image always under constant condition, by recording the image on the basis of the data which is obtained by correcting the data converted by a printing lookup table on the basis of the correction quantity stored in a correction table. CONSTITUTION:After the initial setting of correction data is completed, the recording of an image is started. An interface 31 sends out a selection signal TS to a correction table 32 and the image signals PS of selected sources 11-14 are inputted to a printing lookup table 33. The conversion of data is performed in the table 33 and printing data PD are inputted to a correction circuit 34. In the correction circuit 34, the correction signal CR selected and outputted from the correction table 32 corresponding to a selection signal TS is used to convert not only offset alpha to alphaR but also a gain (g) to gR, for example, with respect to an R-color to correct the data PD to printing data PDA. A G-color and a B-color are also corrected in the same way. This corrected image signal PDA is inputted to a printing part 35 to perform the recording of a color image according to a predetermined system.

Filed: 1985-11-22
Abstract: PURPOSE:To improve the cleaning effect of fixing rolls by making the pressing force of a pressing means of a cleaning pad to the fixing roll in a downstream side in the rotation direction of the fixing roll larger than that in an upstream side. CONSTITUTION:When a uniform pressure is applied to a cleaning pad 4, the downstream side of the cleaning pad 4 in the rotation direction of a fixing roll 1 is raised if the fixing roll 1 is rotated. a pressing force F2 in the downstream side of a pressing spring 2 is made larger than a pressing force F1 in the upstream side of a pressing spring 3 in the rotation direction of the fixing roll 1 to prevent the downstream side of the cleaning pad 4 in the rotation direction of the fixing roll from rising, and the whole of the cleaning pad 4 is uniformly brought into contact with the fixing roll 1. An extent by which the pressing force F2 is larger than the pressing force F1 is dependent upon the force of friction and the pressing force between the cleaning pad 4 and the fixing roll 1. Thus, the cleaning effect is improved.

Abstract: PURPOSE:To distinguish an object to be measured between being located at an infinitely far point and being located at an extremely close point, by receiving a reflected light of light projected to an object being measured from a light source with a semiconductor position detecting element (PSD) through a light receiving lens. CONSTITUTION:On a plane determined by projection optical axis L1 of a projection lens 4 and light receiving optical axis L2 of a light receiving lens 2, reflection surfaces 6a and 6b to be linear and non-linear successively contacted at one end thereof is provided and the reflecting object 6 is provided between a PSD 1 and the lens 2. The reflected light from the object 5 to be measured farther than a specified extremely close point is reflected and forms an image on the PSD 1 at this linear portion while the reflected light from the object 5 within the very close point position is made to reflect and form an image to focus on a specified area of the PSD 1 at the non- linear portion. As an object 6 is provided if the object 5 shall be located at the very close point position, the reflected light is sure to be made incident into the PSD 1. Therefore, the condition that the reflected light from the object 5 does not exist on the PSD 1 is only confined to the existence of the object 5 at a infinitely far point, thereby enabling a clear distinguishing between two locational sate of the object.
