Abstract: PROBLEM TO BE SOLVED: To obtain an image formation system which obtains a print result that a user desires without outputting a unnecessary print form by forming an image according to image-processed image data and judging whether or not received command data can be executed. SOLUTION: An execution judgement part 2d as an execution judging means judges whether or not command data which are sent from a host device 1 and concerned in a specified function can be executed before an image process part 2b as an image processing means processes image data put in a RAM 2h or when an image formation part 2c as an image forming means forms an image of the image-processed data. Thus, it is judged whether or not the command data regarding the specified function can be executed, so the image is not formed while the specified function is not implemented and the user is unaware of that. Thus, the image formation system is obtained which forms no unnecessary image.

Abstract: PURPOSE:To permit exact and easy formation of an enzyme immobilized film and inactivated enzyme immobilized film by bringing a developing soln. of a photoresist into contact with the enzyme immobilized film to inactivate the enzyme of the enzyme immobilized film. CONSTITUTION:The enzyme immobilized film 3 is formed on an ISFET (semiconductor field effect type ion sensor) 1 for an enzyme sensor and an ISFET 2 for a reference sensor. After the photoresist 5 is coated thereon by spin coating, the photoresist is exposed by using a photomask and is developed. The photoresist film covering the immobilized film 3 is then removed. The immobilized film 3 contacts the developing soln. at this time. The pH of the developing soln. is >=13 and the enzyme contained in the immobilized film 3 exposed to such high pH is entirely inactivated to constitute the inactivated enzyme immobilized film 6. The photoresist 5 is removed by acetone after the end of the development. The enzyme sensor 7 and the reference sensor 8 are thus formed. The exact and easy formation of the enzyme immobilized film and the inactivated enzyme immobilized film is thereby permitted.

Abstract: PURPOSE:To suppress the feeling of physical disorder and to improve stereophonic feeling falsely by keeping a low frequency band having high separation as it is, and in a high frequency band deteriorated at its separation, increasing higher level out of right and left levels moreover and reducing lower level moreover. CONSTITUTION:The interruption frequency fc of an HPF10 is selected as fc=5kHz. An envelope detector 12 detects the output of the HPF10 and outputs and output VE1 indicating the level of Lch. Differential amplifiers 14, 16 compare the output VE1 with the output VE2 of an envelope detector in an Rch circuit not shown in figure and generate outputs VC1, VC2 corresponding to their differences. A voltage control amplifier 18 amplifies the output of the HPF10 and inputs the amplified output to a mixer 22 and the gain is controlled by the output VC1, and when VE1=VE2, the gain G is '1'. When VE1>VE2 and VE1<VE2, G>1 and G<1 are formed respectively. An LFP20 passes 5kHz or less signal cut off by the HPF10. The mixer 22 forms the sum of the output of the HPF20 and the output of the amplifier 18 and inputs the sum to the left power amplifier. The Rch circuit executes similar operation. Consequently, separation can be emphasized also in the high frequency band.
