Title: Method for inspection by using nuclear magnetic resonance
Inventor: ONODERA YUKARI
IPC: A61B5/055
Filed: 1993-10-19
Abstract: PURPOSE:To eliminate fluctuation components derived from instabilities of an apparatus, etc., and to attempt to extract the fine changes in signals of time series images by normalizing each time series image by using the integrated values in specified regions. CONSTITUTION:When a detecting system such as a receiver 10, an amplifier 11 and a phase inspector 12 is unstable, it is thought that the signal level and the noise level are fluctuated. In this case, the fluctuation of an image can be corrected by making the integrated value of the voxel value in a normalized factor calculating region to be a normalized factor. When it is assumed that the whole amt. of signals is not changed, e.g. the normalized factor calculating region extracts a signal region by a threshold value treatment. The threshold value is made to be 10-fold of a mean value by making the mean value of the voxel value in the noise region 26 specified on one image selected from the time series images or on a mean image of a plurality of images as a standard. Even in an experimental system with a large fluctuation, a fine change in signal of the time series image can be easily detected.

Title: Image forming device and image forming method
Inventor: UEDA MASATO
IPC: G03G15/16
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent toner from adhering to a guiding member and to obtain an excellent transferred image even under environmentalconditions such as high temperature and high humidity and even in a reversal developing system by applying power source voltage on the guiding member for guiding the transfer paper to a transfer part through a specified resistance. SOLUTION: A constant-voltage power source 33 always applies -100V to charging potential of a photoreceptor having the same polarity as the charge of toner on a plate-like conductive guiding member 32 guiding the transfer paper to the transfer part. A transfer pole 30 is corona-discharged by a transfer power source 31 and imparts charge to the back surface of the transfer paper. The resistance 34 of 10MΩ to 200MΩ, is interposed between the member 32 and the power source 33 in series, and voltage is applied on the member 32 from the power source 33 through the resistance 34. Thus, the voltage is held on the member 32 when the discharge of a transfer device is not performed, and a situation that the toner flying from the surface of the photoreceptor 16 adheres and soils is eliminated. Furthermore, even in the case of using the reversal developing system, the toner is prevented from adhering because the member 32 is maintained at the high potential having the same polarity as the toner.

Title: Method of temperature control baking and drying furnace
Inventor: MOROOKA HIDEAKI
IPC: C21D11/00
Filed: 1990-09-28
Abstract: PURPOSE:To eliminate a useless supplying of hot air caused by a difference in temperature increasing capabilities between each of the zones and its corresponding hot air supplying device and to enable an energy to be saved by a method wherein an actual inter-furnace temperature at a specified zone showing the longest temperature increasing time is applied as a target temperature and an increasing temperature in another specified zone is operated in compliance with its following-up operation. CONSTITUTION:When each of hot air supplying devices 10a, 10b and 10c is concurrently energized, a set temperature TL is applied as a target value and then a temperature increasing operation is carried out with an actual inter-furnace temperature Ta in a specified zone 1a being applied as a feedback signal. Accordingly, although the temperature Ta within the specified zone 1a is increased as indicated by a solid line curve, another hot air supplying device 10b (10c) is operated to increase its temperature with the actual inter-furnace temperature signal Ta detected from the specified zone 1a outputted from a terminal 0 of a temperature controller 20a being applied as a target value and a temperature Tb (Tc) actually detected from the zone 1b (1c) being applied as a feed-back signal. That is, the operation is automatically followed to a temperature increasing curve in the slowest specified zone 1a and another zone 1b (1c) is increased in its temperature, so that there is a certain time lag and the actual inter-furnace temperature Tb (Tc) concurrently reaches the set temperature TL at the time (t1) when the inter-furnace temperature Ta reaches the set temperature TL.
