Abstract: PROBLEM TO BE SOLVED: To suppress the generation of an unnecessary electric field and charge by providing a probe, a moving means, an interaction detection means, a holder and a same potential holding means always holding the conductive part of a sample of which a part is conductive and the conductive part of the probe at the same potential. SOLUTION: A probe 104 is fixed to the leading end of a cantilever 103 and made of silicon nitride and a Pt membrane 114 is formed on the surface of the probe 104. The membrane 114 is connected to a holding member by the wiring arranged in the cantilever 103 and the leading end of the membrane is brought into contact with a sample 102 to be observed. The sample 102 and a sample holder 101 are fixed with a conductive adhesive. A sample driving mechanism 105 moves the holder 101 in X-, Y- and Z-directions. The probe 104 is coated with Pt and, since the potential thereof is the same as that of the holder 101, the sample 102 and the membrane 114 are almost equal in potential and, therefore, an unnecessary electric field is not generated in the vicinity of an observation point and accurate measurement can be performed.

Title: Developing device
Inventor: TAKANO SHINICHI
IPC: G03G15/08
Filed: 1985-02-12
Abstract: PURPOSE:To generate fine pores by subjecting a developer holding member consisting of aluminum or aluminum alloy or nonmagnetic stainless steel contg. internally a magnetic field generating mechanism to DC electrolytic etching in an acidic soln. CONSTITUTION:Dissolution is considerably nonuniform if an environmental oxidizing agent and halogen ions exist in the acidic soln. in aluminum, aluminum alloy or stainless steel. There is a tendency to the progression from nonuniform corrosion to overall dissolution when the concn. of the halogen ions increases to >=10mol/l. The nonuniform corrosion progresses hardly at the low liquid temp. and >=60 deg.C is practicable. The influence of electrolytic current density is such that the density of the pores indicates a peak at certain current density and the pore size increases gradually thereafter. The circuit for electrolytic etching is constituted by disposing a counter electrode 2 to a member to be subjected to the surface treatment so as to face said member, connecting the electrodes through an external power source 3 and dipping the electrodes into the aq. acidic soln. 4 having electrical conductivity.

IPC: C21D1/10
Filed: 1994-01-27
Abstract: PURPOSE:To uniformly harden over the whole periphery of a ring gear by arranging a bimetal on the outer periphery of a fitting part, in an induction hardening jig having the fitting part for seating the ring gear on the outer periphery. CONSTITUTION:The bimetal 6 composed of a high and a low heat expanding materials respectively stuck to the inner and the outer peripheral sides is arranged to the recessed part 8 arranged at equal interval in the peripheral direction of a vertical wall part 4 for regulating the inner periphery of the ring gear 11 in the almost cylindrical shaped induction hardening jig 1. Successively, the ring gear 11 is seated to the fitting part 2 composed of a shoulder part 3 and the vertical wall part 4 of the jig 1. In this condition, the bimetal 6 and the ring gear 11 are not brought into contact with each other in their most. Then, a heating coil is arranged at the outer periphery of the ring gear 11, and the hardening of the tooth part 12 of the ring gear 11 is started by induction hardening heating with high-frequency current. At this time, the bimetal 6 is heated also and bent to the outer peripheral side over the whole periphery to uniformize clearance between the vertical wall part 4 and the inner periphery of the ring gear 11 over the whole periphery. Owing to this condition, heating without any unevenness is executed, and after heating, water-cooling is executed to complete the hardening.

Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To reproduce the images of small noise and high image quality without causing image flowing by synthesizing images obtained by picking up the plural images by integration time equal to or less than hand shake limit integration time when object luminance is low. SOLUTION: When the object luminance is low and the possibility of causing a hand shake is present, in order to prevent it and to obtain the high quality images, in a pixel non-addition mode for outputting the charge amounts of the respective pixels of an image pickup element 110 as they are as pixel data, plural image data picked up by the hand shake limit integration time or the integration time shorter than that are synthesized and one piece of final image data is obtained. Further, since a camera position is moved after first image photographing until the image pickup of second and succeeding times, the image data of the second and succeeding times are corrected and added to the first image data.  In this case, since the respective images are picked up by the hand shake limit integration time or the integration time shorter than that, no hand shake is present even in an exposure insufficient state and it is the position correction of the image read from the image pickup element 110 to be strict and is different from the image correction to be the hand shake.

Title: Chirp signal receiving device
Inventor: IZUMI ISAO
IPC: G01S7/285
Filed: 1986-02-08
Abstract: PURPOSE:To expand the dynamic range of a receiver by providing a matched filter for compressing a chirp signal to an AGC circuit. CONSTITUTION:The matched filter 5 for compressing the received chirp signal is interposed between a variable gain amplifier 1 and a detector 3. The matched filter 5 is realized by using an SAW dispersion type delay line which has the opposite chirp characteristics from the received chirp signal. The signal when passing through the SAW dispersion type delay line is detected coherently to increase in signal level and noises have no coherency, so only the compressibility of the SN ratio is improved without reference to the noise level. Consequently, even if the SN ratio decreases, the SN ratio in the AGC circuit is improved by the compression ratio, so the dynamic range of the receiver is widened.

Abstract: PROBLEM TO BE SOLVED: To prevent lenses of a light emitting element and a light receiving element in a density sensor and a transmissive cover from being soiled by a developer by making the density sensor movable, and bringing it close to an object to be measured, only at the time of a density control sequence. SOLUTION: The movable part of the density sensor 50 moves apart from a transfer drum 10 by means of a spring 81, an arm 82 is connected to a clutch 80 and the density sensor 50, and the density sensor 50 is pushed out so as to come close to the transfer drum 10 by the operation of the cloth 80. The operation sequence of the density sensor 50 brings the density sensor close to the transfer drum 10 by the movable part of the density sensor 50 when a printing operation is performed, when a fur brush is operated, when a jam is detected, and when a door is opened. Since the problem that the lenses of the light emitting element and light receiving element of an image density controller, the transmissive cover and the like are soiled by the developer is eliminated, the sensitivity of a density measuring device can be kept high.

Abstract: PURPOSE:To transfer message data quickly without having the influence upon the processing of a processor, by providing a transfer bus switching control circuit which processes freely message blocks accumulated in a line buffer. CONSTITUTION:When a message block comes from an input/output line 1, a processor 5 transmits the indication for selection of the line 1 to a selecting circuit 10. Simultaneously, the processor 5 transmits the indication for selection of a transfer bus 12 to a transfer bus switching control circuit 11 to accumulate the coming message block in a line buffer 2. When the buffer 2 is filled up, the processor 5 transmits the indication for selection of a bus 8 to the circuit 11 and transfers processed messages from the buffer 2 to a file 4 through the bus 12 and a file buffer 3 to accumulate them in the file 4 after required processings. Thus, the processor can process freely message blocks accumulated in the buffer 2 through the bus 8 and the circuit 11, and message blocks are transferred quickly without having the influence upon the processing of the processor.
