Title: Image forming device
Inventor: SHIMIZU TADAFUMI
IPC: G03G15/00
Filed: 1990-02-16
Abstract: PURPOSE:To enlarge an adjustment range for obtaining prescribed image quality by controlling toner supplying quantity, setting toner concentration as set concentration and varying the set concentration when the relative electric potential of a latent image carrier surface potential and a developing means bias potential is controlled to be limit value. CONSTITUTION:The toner supplying quantity is controlled by a CPU 201 through the developer replenishing motor 78 of a developing device so that the toner concentration measured by a toner concentration sensor 80 is set as the set concentration. Then the relative electric potential of the latent image carrier surface potential measured by a surface electrometer 90 and the bias potential supplied to a development sleeve 71 is controlled by the CPU 201 and image quality is adjusted. When the adjustment reaches limit value, the set toner concentration is varied and the same repetition is performed. Then the adjustment range for obtaining the prescribed image quality is enlarged and wide- ranging action is performed in response to the performance deterioration of each part.

Title: Operation of soot blower for air preheater
Inventor: KANEKO TAKUMA
IPC: F23J3/00
Filed: 1987-02-20
Abstract: PURPOSE:To secure the operation of a soot blower for an air preheater by a method wherein after the operation is started, drain and high pressure steam are discharged before the soot blower reaches air preheater elements and then soot blowing operation is carried out with a fixed pressure. CONSTITUTION:From the upstream to the downstream of the steam flow in a soot blower steam system 9 for an air preheater branched off from a soot blower steam system 8 for a boiler mainbody, a pressure reducing valve 25, a pressure switch 26, and a stop valve 12 opened and shut by the signal from the switch 26 are installed in order.

Title: Extension card device and extension card control method
Inventor: NOBUTANI TOSHIYUKI
IPC: G06F13/36
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce radiation noises with data transfer while improving data transfer throughput by limiting unwanted data transfer access by outputting data, which are to be outputted to an internal bus, onto an external bus when a detecting means detects data transfer access to the external bus. SOLUTION: An address recorder 201 analyzes an address to be outputted to an internal bus PCMCIA and detects the data transfer access to an external bus EB. When the address recorder 201 detects the data transfer access to the external bus EB, an address translation circuit 202 controls data transfer so as to output the data, which are to be outputted to the internal bus PCMCIA, onto the external bus EB. Thus, when extending the internal bus PCMCIA to the external bus EB, data transfer is enabled by detecting access to the external bus EB and the radiation noises with data transfer can be reduced while improving data transfer throughput while limiting the unwanted data transfer access.

On the other hand, a converter circuit 1b outputs an output Eb in response to the setting by a setting circuit 2b to which a voltage level in response to the frequency of the space signal is set. When an inverter control circuit 40 outputs a frequency command C of the mark signal to an inverter circuit 3, a transistor(TR) 7a is conductive and when the inverter control circuit 40 outputs a frequency command C of the space signal to the inverter circuit 3, a transistor(TR) 7b is conductive. Thus, the output of the converter circuits 1a, 1b is adjusted so that each signal outputted to the distribution line 6 via a coupling circuit 5 has an equal voltage level.

Abstract: PURPOSE:To detect exactly the distortion in the sugar coating layer of a sugar coated tablet without contacting by forming a hologram in the state before and after moisture absorption of the sugar coated tablet by a laser holography, irradiating laser light thereto and observing the developed interference fringe. CONSTITUTION:A thoroughly dried sugar coated tablet is used as a sample 7, and a hologram dry plate 6 is exposed primarily by a hologram. The sample is maintained for a prescribed time under a constant temp. and constant humidity condition and the hologram dry plate is similarly subjected to secondary exposing with respect to the sample in which moisture is absorbed. When a laser beam is irradiated to the hologram dry plate subjected to double exposing in such a way, the fringe pattern corresponding to the rate of deformation in the sugar coated tablet before and after the moisture absorption is developed on a reproduced image. The deformation is more progressed and a crack is more likely to arise with the developed fringe pattern having the narrower space between the fringes, that is, having the larger number of the fringes.
