Title: Measurement of rotational irregularity and rotations of rotary body
Inventor: MOGI SHINICHIROU
IPC: G01P3/44
Filed: 1978-03-17
Abstract: PURPOSE: To improve the measuring accuracy of rotational irregularity and rotations by making a rotary body and by taking the mark at a preset time interval so that the distance of the image of the marks at the preset time interval may be measured together with the time period for which the mark is turned once.  
     CONSTITUTION: A mark 10 is turned by a rotary body 9, and the rotations are taken by a lens 13 in a measuring cylinder 12 and an image pick-up element 14. The locating signals by the element 14 are calculated and processed by a measuring device 15 to indicate the rotating performance. The calculations are accomplised by taking the body 9 at a time internal t, by placing the position of the image at an instant at points 16, 17, 18 and 19 by calculating the distances l 1 , l 2  and l 3  between the points and by rearranging the distances while using the time t as an abscissa and the inter-point distance l as an ordinate. Then, envelope 23 connecting the apexes becomes the component in the rotation irregularity. On the other hand, the number of rotations can be calculated by measuring the time period for which the image is returned to the position of the image 16.

Title: Icp emission analyzer
Inventor: OKADA KOJI
IPC: G01N21/73
Filed: 1987-02-12
Abstract: PURPOSE:To detect the presence of a plasma ignition surely, by a method wherein detection sensitivity of a photoelectric detector is set at a specified level and first and second discrimination circuits are arranged. CONSTITUTION:Detection sensitivity of a photoelectric detector 24 is so set to output an ignition detection signal as the quantity of light received from a plasma torch 2 exceeds the quantity of light in a pilot plasma state. A first discrimination circuit 26 outputs a first signal to lower a high frequency power to be supplied to the torch 2 to the level of the pilot plasma state in response to the ignition detection signal. Therefore, in the ignition as complete ionization plasma, the pilot plasma state is maintained but when the ignition fails, the torch 2 is extinguished and no ignition detection signal is outputted. After the high frequency lowers by a signal from the circuit 26, a second discrimination circuit 28 is started. Under such a condition, the ignition detection signal given from the detector 24 indicates that the plasma ignition state is maintained, and in response to this signal, a second signal for permitting the start of measurement is outputted. As a result, the presence of plasma ignition can be detected surely even when the detection sensitivity of the detector 24 remains at a fixed value.

Title: Thermal head
Inventor: OBATA SHINOBU
IPC: G06K15/00
Filed: 1992-02-18
Abstract: PURPOSE:To take a clear image of an alignment mark and convert it to a binary image at all times by a method wherein protective film is formed so as to cover at least electrode and head generating resistor and not to cover at least one alignment mark. CONSTITUTION:Electric insulating protective film 20 for covering the surface of substrate 10 is formed so as to cover at least electrode 18 and heat generating resistor 16 and not to cover at least one alignment mark 14. Concretely, at least one alignment mark 14 is excluded from the region covered with the electric insulating protective film 20. The lowering of the light transmittance of the protective film, its surface roughness and the like are the factors, which prevent the clear imaging of the alignment mark, and the image can not be obtained. In order to remove the above-mentioned factors, no formation of protective film 20 over the alignment mark is enough. However, from the necessity of the isolation insulation of the electrode and the like, the region, in which no protective film is formed, is made as well as possible and the protective film is formed so as to cover at least the electrode 18 and the heat generating resistor 16.

IPC: G03C7/26
Filed: 1981-03-03
Abstract: PURPOSE: To enable rapid color development using a color developing agent containing a paraamine type developing agent without black-and-white developing, by adding a specified 3-pyrazolidone compound to a silver halide color photosensitive material.  
     CONSTITUTION: A 3-pyrazolidone compound represented by the formula (X being H, CH 3 CO, R being aryl, R 1 WR 4  being H or alkylaryl) is added to the silver halide emulsion layer of a silver halide color photo-sensitive material, or to the adjacent layer, especially to the subbing layer on the base of the photosensitive material, or the lowest layer adjacent to the subbing layer. A paraamine type developing agent is not contained in the photosensitive material, but in a developing solution in an amount of 1W12g/l to develop the material, thus permitting a color image having high maximum density to be formed without doing black-and-white development rapidly, for example, at 33°C within 1min.

IPC: D06F79/02
Filed: 1989-02-09
Abstract: PURPOSE:To prevent in advance overheating, burning and a fire of a placing base caused by a base by placing an iron body in an inclined state being different from a normal position so that in the case when the base abuts on a projected wall of the placing base, a power receiving pin is separated from a feed plate and an electric conduction to a heater is disconnected. CONSTITUTION:In the case when an iron body 1 is placed in a state inclined to the left and the right being different from a normal position, as the case may be, it is held in a state that a rear end A of a base 2 abuts on the upper face of a projected wall 16a, a corner angle part B of a rear 8 hits against a bottom wall 17 and an opening part end edge C of a void 10 hits against the outside peripheral wall surface of a bulge part 23. In this case, the abutting part of the corner angle part B of the rear plate 8 becomes a supporting point and the corner angle part of the opposite side to the corner angle part B of the rear plate 8 becomes high. Therefore, one power receiving pin 12a is depressed strongly in a state connected to a feed plate 31a, but the other power receiving pin 12b is separated from a feed plate 31b and an electric conduction to a heater 3 is disconnected. Accordingly, overheating, burning and a fire of a placing base caused by the base are prevented in advance.

Title: Method of regulating braking force of motorcycle
IPC: B60T8/26
Filed: 1993-01-08
Abstract: PURPOSE: To enable comfortable braking by a method wherein a motorcycle deceleration value when a lift-off signal is generated is stored as a deceleration limit value and, when the deceleration of a motorcycle in drive exceeds the deceleration limit value and the increase of the motorcycle deceleration exceeds an allowable maximum value, a braking pressure applied to a front wheel is reduced and successive lift-off is avoided. CONSTITUTION: A wheel electronic controller 2 has a lift-off detection/dissolution mechanism 4 and a lift-off preventive device 5. The lift-off detection/dissolution mechanism 4 transmits a signal indicating the existence of a serious lift-off state to the lift-off preventive device 5. Then, a lift-off signal is supplied from the lift-off preventive device 5 to a pressure modulator 1 and the pressure of a front wheel braking circuit is reduced. In this control regulation method, first, a motorcycle deceleration value when the lift-off signal is generated is regarded as an optimum deceleration point and stored as a deceleration limit value.  If, following the change in the reference point of a motorcycle in drive, the deceleration value to be stored changes and exceeds the deceleration limit value and the increase of the deceleration value exceeds an allowable maximum value determined in relation to the motorcycle acceleration, the motorcycle reference speed and the deceleration limit value, the lift-off signal is supplied.

Abstract: PURPOSE: To make the amount of excess developer smaller than heretofore by using an elastic body in which the diameter of a hole on its surface is in a specified range as an elastic body. CONSTITUTION: As to a developing roller 25; a surface layer constituted of porous elastic body 33 in which the diameter of the fine hole is <=100μm, and desirably <=60μm is provided on a conductive core material 32.

That is, the diameter on the elastic body 33 is less controlled than heretofore, and the distribution density of the fine hole is controlled, so that the remaining amount of the excess liquid remaining on the surface of a photoreceptor 20 can be reduced in comparison with conventional reverse roller method.  Mesh and the mark having the shape of the fine hole are prevented from occurring on the surface of the photoreceptor.
