Filed: 1993-06-29
Abstract: PURPOSE:To automatically switch a transmission path so as to provide displaying on a monitor TV installed in a front operation stand regardless of whether the forward or the rearward signal is received. CONSTITUTION:A high frequency signal outputted from a front light receiver 22b is distributed by a high frequency distributor 3 to a switching controller 32 and a light receiving circuit part 23b. The high frequency signal outputted to the switching controller 32 is level-detected by a wave detector 33 and then compared with a reference voltage value by a voltage comparator 34. When the detected signal voltage is larger than the reference voltage value, the switching controller 32 switches a change-over switch 35 to a contact point C2 to select a second transmission path 24b so as to display an image from a forward light transmittor on a monitor TV 36 provided in a front operation stand 3. When the light receiving signal from the light receiver 22b is not available, the switching controller 32 switches the change-over switch 35 to a contact point C1 to select a first transmission path 24a so as to display an image from a rearward light transmittor on the monitor TV 36.

Title: Ignition coil having unfiltered/unsorted secondary winding separator and manufacuture thereof
Inventor: CHIYAARUZU AARU SHIYUNAIDAA
IPC: H01F27/32
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the cracking and deterioration of a filler barrier and an enclosure caused by the related change of the composition by replacing a paper layer which separates wiring layers from each other in a secondary winding with a solid filament nylon mesh. SOLUTION: A paper separating layer 126 and/or a paper protective layer is replaced with a solid filament nylon mesh 128. Since the mesh 128 does not absorb not adsorb any component of an enclosed compound, the chemical property of the enclosed compound does not change near paper 124. The enclosed compound not only fills up the space between a secondary winding 132 and the mesh 128, but also fills up the space between different layers 132 of the secondary winding through the mesh 128. Therefore, the appearance of inductive discontinuity between the layers 132 of the secondary winding is reduced. When the mesh 128 is used, the cracking of the layer overlying the paper 124 is reduced, because the enclosed compound can flow sufficiently through the overlying layer before the compound hardens.

Filed: 1989-06-21
Abstract: PURPOSE:To make an apparatus compact and to make it possible to perform accurate measurement by processing the image through a microscope when fluorescence is emitted from a sample by the projection of light from a light source for a short time. CONSTITUTION:Luminous flux from a light source 1 passes through an exciting filter 3 with the opening and closing of a shutter part 2 for a short time, and the exciting light having a first wavelength is formed. The exciting light is reflected from a dichroic mirror 4 and projected on a sample (a) on a stage 6 through an objective lens 5. The image of the luminous flux of fluorescence emitted from the sample by the exciting light is picked up with a camera 8. The image is stored in the frame memory of an image processing device part 9 through the shutter part 2. Then, the luminous flux from the light source 1 passes through the exciting filter 3 having the exciting wavelength that is different from the first time. Thus the exciting light having the second wavelength is formed. The image of the excited light is picked up and stored in the frame memory of the image processing part 9. The fluorescent surface images which are obtained in this way using two wavelengths undergo operation between the images in the image processing device part 9. Namely, the value of quotient between the two images and the logarithmic value are obtained. The values are converted into pH using a calibration curve which is prepared beforehand. Thus the accurate measurement becomes possible.

Title: Toner image fixation method
Inventor: KUZUMI KENICHI
IPC: G03G15/20
Filed: 1982-09-14
Abstract: PURPOSE:To perform toner image fixation which never causes back surface contamination by allowing at least polyhydric alcohol to reside at a member which contacts the outer circumferential surface of a fixing roll directly or indirectly. CONSTITUTION:A cleaning roll 4 collects sticking toner on a heat roll 1 over its outer circumferential surface. In this case, the polyhydric alcohol comes out of an internal liquid holding layer 6 to the outer circumferential surface of the roll 4, so toner collected on the outer circumferential surface or deposited material increases in elasticity when dissolved and the heater 3 of the roll 1 is turned on; even when the toner material on the roll 4 is heated and dissolved, it is inhibited from moving to the roll 1 and also inhibited from moving to a press-contacting roll 2 as a result, so that back-surface contamination is prevented.
