Title: Magnetic element detector
Inventor: MIYAUCHI TADANORI
IPC: G01V3/11
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a structure capable of accurately detecting a magnetic element with high stability even when a small magnetic element is mixed at any position of a large article in a tunnel type magnetic element detector. SOLUTION: A passageway 9 surrounded by a pole surface N of the same polarity of a permanent magnet 8 for forming the passageway, having a sectional shape in which a large article can pass and substantially uniform magnetism therein is fully activated. A magnetic flux from an opening of the passageway 9 is concentrated toward a permanent magnet 10 disposed near an edge of the opening of the passageway 9 to concentrate a reverse polarity leakage magnetic flux, and a sensing area in which the flux is concentrated is formed in a small width along an overall surface of the opening. A magnetic change due to a magnetic element 6 introduced into or outputted from the area is detected by a magnetic sensor 11 disposed near the magnet 10 for concentrating the leakage magnetic flux.  Further, the magnets 10 are disposed at both an inlet and an outlet of the passageway, and the passageway 9 is surrounded by a magnetic coupling material 13 having a large thickness, a non-magnetic element 14 and a magnetic shield plate 15 to remarkably reduce the external leakage magnetic flux.

Title: Image retrieving device
Inventor: HARADA SHIGEKI
IPC: G06T1/00
Filed: 1993-09-29
Abstract: PURPOSE:To easily designate a desired partial image in an image file where the partial images are projected. CONSTITUTION:When an image of a large original size is divided into blocks and then fetched as the image data, a retrieval control means 110 displays a reduced image in response to the original image with no limitation caused by the divided boundaries. Then the area designated by an input means 111 is pointed in the reduced image by a selected area pointing means 19. Therefore an operator can recognize the designated area in relation to the entire original image. The selected area display means 14 and 17 show the areas designated by the means 111 in the windows different from that of the reduced image. Thus the operator can recognize an area that is designated regardless of the entire original image. Then the operator can correctly recognize the display contents when the image data of the designated area are displayed.

Abstract: PROBLEM TO BE SOLVED: To provide a gas and dust collecting system which can easily and automatically prepare a sample for component analysis containing a contaminant contained in an environmental gas at a high concentration which is hundreds times as high as that in the environmental gas and has a small size and light weight. SOLUTION: In preparing an assay sample by mixing an appropriate amount of pure water steam in a gas sucked from the environment and cooling the mixture in a condenser 8 comprising a condensation tube 9 and a heat sink 8a together with the water originally contained in the sucked gas, the sucking amount of the gas and mixing amount of the pure water steam are adjusted and controlled by means of a feedback control system, etc., so as to control the preparing speed of the assay sample. By taking into consideration that the concentration of the contaminant to be determined in the environmental gas is very low, the inside of a gas and dust collecting system constituted in such a way is carefully cleaned before a new assay sample is collected so that the contaminant sucked in a previous old environment and remaining in the system cannot affect the analyzed results of the new sample.

Title: Pwm drive circuit
Inventor: YASUKI SHINICHI
IPC: H03K17/04
Filed: 1987-09-28
Abstract: PURPOSE:To attain normal operation even when a potential at an output terminal is lower than the ground potential by providing a diode for preventing reverse current between a collector of a stored carrier extraction transistor(TR) and a base of an output TR. CONSTITUTION:In conducting a switch 9 in the timing when a switch 11 is interrupted to quicken the switching speed, the potential at an output terminal 4 is lowered than the ground potential by a forward voltage of a diode 7 and even when the forward voltage gets higher, a diode 13 is used as a reverse flow preventing diode. When the voltage exceeds the reverse dielectric voltage of the diode 13, so long as the voltage at the output terminal 3 is not lower than the ground potential, the PN junction between the base and collector of an NPN TR 8 is in the forward polarity and an NPN TR 3 is not conductive. Thus, the drive efficiency in using the titled circuit as a PWM(Pulse Width Modulation) drive circuit is improved.

IPC: G03G21/00
Filed: 1988-09-27
Abstract: PURPOSE:To save trouble for selecting a power saving mode and to enhance a power saving effect as much as possible without lowering operating efficiency by selecting a normal mode and the power saving mode according to the presence or absence of people in a place where a copying machine is installed. CONSTITUTION:Sensors 52 and 53 detect the number of incoming and outgoing people in the place where the copying machine A is installed, and the outputs are transmitted to a computer 51. It judges whether the detected visitors are allowed or not, and if not, controls them to prohibit from entrance or stores the number of visitors. Based on the output from the computer 51, the copying machine A selects the normal or power saving mode according to the presence or absence of people in the place where the machine A is installed. In such a manner, when there is no visitor, the machine selects the power saving mode, and therefore the normal mode is not continued in spite of the absence of an operator, thereby reducing consumed power without trouble.
