Title: Picture discriminating device
Inventor: KUSANO HIDEAKI
IPC: H04N1/40
Filed: 1986-06-23
Abstract: PURPOSE:To discriminate a picture as a negative or a positive of a line picture by obtaining a function which has a maximum value or a minimum value, an average value, and a deviation value of the picture element density as variables and comparing this function with a threshold function which has the maximum value or the minimum value as a linear variable. CONSTITUTION:The picture element density of the picture is read by a line sensor 11. A maximum value Dmax, a minimum value Dmin, an average value Dave, and a deviation value sigma of the read density are obtained by a microprocessor 9p. Functions A1+(Dmax-Dave)/sigma and A2=(Dave-Dmin)/sigma having these values as variables are obtained, and values of these functions are compared with preliminarily set threshold functions to decide the picture as a gradation picture, a positive of a line picture, or a negative of a line picture. Functions T1 and T2 (for example, T1=(3.8-Dmax)2 and T2=(3.8-Dmin)/2) with the maximum value Dmax and the minimum value Dmin as linear variables are selected as threshold functions.

IPC: G01J5/48
Filed: 1992-05-12
Abstract: PURPOSE:To obtain an infrared-ray image or a visible ray image by changing over a lens in a thermography device using an infrared-ray lens. CONSTITUTION:Infrared rays from a visual field are directed to an infrared-ray lens through a vertical scanning mirror 31 and a horizontal scanning mirror 33, and after they are focused by the lens 39, they are led to an infrared-ray detector 38 through a relay lens 37 for detection. A lens 40 for visible light is fixed on the same base 41 where the lens 39 is fixed thereon, thereby making them attachable or detachable alternately in a light path by moving the base 41. Since a switching mirror 42 is also attached to the base 41, when the lens 40 is inserted into the light path, the mirror 42 will be also inserted into the light path consequently, and a visible ray focused by the lens 40 will reach a visible ray detector 43 through the mirror 42 for detection. An output signal issued from the detector 43 is supplied to a display to obtain a visible ray image.

Title: Fault diagnosis method for exhaust valve
Inventor: FUKUYOSHI TADASHI
IPC: G01H17/00
Filed: 1989-06-12
Abstract: PURPOSE:To perform fault diagnosis objectively and highly accurately by detecting vibration when an exhaust valve comes into contact with a valve seat, detecting a crank angle when the exhaust valve comes into contact, analyzing the vibrating frequency at this time, comparing the frequency with the analyzed value of the vibration frequency obtained at the normal time beforehand, and judging the presence or absence of the fault of the exhaust valve. CONSTITUTION:Vibration when an exhaust valve 104 comes into contact with an exhaust valve seat 105 is picked up by a vibration sensor at good timing, and the frequency is analyzed. The rate of the high frequency spectrum occupied in the entire spectrums is computed. Whether the valve is normal or abnormal is judged based on the magnitude of the value. Since the high frequency vibration tends to attenuate quickly, a powerful magnet 111 is mounted in the sensor 110 so that the searching point for the vibration source can be freely changed. A rotary-angle detecting sensor 119 is used for detecting the seating timing of the exhaust valve 104. The movement of a pin 118 which is provided at a flywheel 108 and the like is detected, and a crank angle is computed. In this way, the fault diagnosis of the exhaust valve 104 can be performed objectively and highly accurately.

IPC: A61L27/00
Filed: 1988-06-15
Abstract: PURPOSE:To easily prepare a ceramic porous body having a stable void form and a void ratio without generating harmful exhaust gas by a method wherein a foaming agent and a fibrous substance are added to the suspension of a raw material powder under stirring and, after the resulting mixture is dried, said mixture is calcined to remove the fibrous substance and baked. CONSTITUTION:As ceramic raw materials, hydroxyapatite, a calcium phosphate type compound, alumina, silica, zirconia or the like are used. As a foaming agent, hydrogen peroxide or egg white is used and, as a fibrous substance, for example, common Japanese writing paper or toilet paper dispersible in water is used. By changing the mixing ratio of these components, a void ratio can be easily controlled but, in order to obtain one having a void ratio of 40% or more, 0.1-0.5% of the foaming agent and 2.0-2.5% of the fibrous substance are added to a suspension. By adding the fibrous substance, shrinkage at the time of drying is suppressed and a porous body having a uniform void form is obtained. This mixture is sufficiently stirred to be dried and calcined at about 700 deg.C to remove the fibrous substance while the calcined mixture is molded into an arbitrary shape to be baked at 900-1400 deg.C.

Title: Transmission-characteristic measuring apparatus for optical fiber
Inventor: IDE TAKASHI
IPC: G01M11/02
Filed: 1987-06-12
Abstract: PURPOSE:To improve measuring accuracy, by providing at least two light receiving surfaces in a light-amount detecting means, and forming detected light- amount signals in correspondence with the amounts of the received lights from the light receiving surfaces. CONSTITUTION:The light emitted from a cut end 43 of a cut optical fiber 4' to be measured is detected with a photodetector 5. The photodetector 5 forms individual detected light-amount signals corresponding to the incident-light amounts through at least two light receiving surfaces. The signals are supplied to a control device 9. The device 9 processes and operates each of the input signals and judges whether or not the optical coupling between the cut end 43 and the photodetector 5 is good. When the coupling is good, an attenuating amount of light is obtained and a transmission loss is determined. When the coupling is inadequate, the device 9 sends a driving signal to a moving stage 8 so as to move the photodetector. Thus the coupling with the cut end 43 is adjusted. When the coupling does not improve, the device 9 sends a reject signal (a) so as to indicate that this optical fiber 1 is not suitable for measurement. In this way the measuring accuracy can be improved.
