Title: Fault detector for sheet-like body
Inventor: TAKEYA YOSHIYUKI
IPC: G01N21/89
Filed: 1980-12-09
Abstract: PURPOSE:To obtain an easy-to-handle, inexpensive detector by providing a front- end and a rear-end detection part before and behind a fault photodetection part and starting and ending inspection automatically. CONSTITUTION:Sheet-like bodies 11 and 12 to be inspected are fed in a direction P successively and when those sheet-like bodies 11 and 12 are not present, photodetection parts 20-22 are irradiated with light from a projection part, so that a discriminating circuit 30 and signal processing circuits 31 and 32 output signals 1 respectivey. At this time, the signal from the circuit 31 is inverted by an  NOT circuit 4 to reset an FF5, and an AND circuit 7 sends no fault signal Q.  When the sheet-like body reaches the front-end detection part 21, and FF5 is set  and if a fault is present, an FF6 is set, so that the AND circuit 7 generates a  fault signal Q. The signal of the AND circuit 7 is inputted to an FF8 and when  the sheet-like body passes through the rear-end detection part 22, the FF8 is  reset by the output of a timer 9, so that an AND circuit 10 outputs a defective rejection signal R. Thus, an easy-to-operate, inexpensive fault detector is obtained.

Abstract: PURPOSE:To uniformalize the distribution of magnetic flux, and to decrease core loss by making dimensions in the radial direction larger than a central section of a tooth in both end sections of an opening section of a rotor slot and enlarging a distance with a stator of said section. CONSTITUTION:The rotor slot 12 has the opening section 14 on a circumferential surface at the side opposing to the stator, and a nose section of the tooth 11 takes a form concentric to the stator.

Title: Manufacture of oxide superconductive wire material
Inventor: HASEGAWA TAKAYO
IPC: H01B12/06
Filed: 1990-06-28
Abstract: PURPOSE:To reduce the lowering of a characteristic due to the generation of impurities and also improve formability, by conducting the air phase addition of Bi which is a low melting point element, to an amorphous wire material containing Sr, Ca, Cu at a predetermined ratio. CONSTITUTION:An approximate agreement with the ratio of elements constituting a Bi superconductive oxide is made by using Sr, Ca, Cu respective oxides and carbonic oxides, that is, the mixed powder of SrCO3, PbO, CaCO3, CuO or the like, and an amorphous wire material is manufactured by cooling rapidly this material substance out of a melting state. As for the method of conducting Bi air phase addition to this wire material, it is to seal the material together with a gas generation source. This heating treatment should be within the temperature range of 500-900 deg.C degrees, as the diffusion of elements from the gas generation source becomes insufficient in the case of the temperature being less than 500 deg.C degrees and the melting of the amorphous body is caused in the case of over 950 deg.C degrees. As for the gas generation source on the occasion of air phase addition, a pseudo burnt power unformed body of superconduction formation is used. As a result, the generation of impurities can be restrained, and a Bi system superconductive wire material superior in formability can be easily manufactured.

Abstract: PURPOSE:To reduce the distance between cavities, runners and gates and heaters so as to reduce the delay in heat transfer and consequently to solve the trouble of heating delay by a structure wherein the cavities, runners and gates are assembled in the interior of plates, in which heaters are arranged. CONSTITUTION:When resin flows out of a cull 7 into main runners 8 and runners 9, center blocks 1a and 2a are cooled by the resin, the temperature of which is relatively lower than those of the blocks. By detecting the tempera ture drops of the center blocks 1a and 2a, thermocouples 20 turn ON heaters 19 in order to heat the center blocks 1a and 2a. At this time, the main runners 8 and the runners 9 are rapidly and effectively heated, because both the heaters 19 and the center blocks 1a and 2a are assembled in the interior or retainer plates 3a and 4a. After that, when the resin is successively poured from the runners 9 of the center block through the gate 12 of each cavity 10, the tempera ture of chase blocks 1b and 2b are lowered at every cavity 10. At this time, the thermocouples 20 detects the temperature drops and turn ON the heaters 19.

Title: Ultraviolet-absorber precursor compound, photosensitive resin composition containing the same, and image formation method
Inventor: SATO MORIMASA
IPC: C08F2/48
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain a photosensitive resin compsn. which allows ultraviolet rays to sufficiently reach the depth of a film formed from the compsn. to effect curing at the step of image formation and exhibits an increase in ultraviolet-absorbing capability when subjected to succeeding heat treatment by using a specific ultraviolet-absorber precursor compd. SOLUTION: This compsn. contains an ultraviolet-absorber precursor compd. represented by formula I  wherein A is a group represented by formula II [wherein R1 is a (substd.) alkylcarbonyl, a (substd.) aralkylcarbonyl, a (substd.) arylcarbonyl, or a (substd.) alkoxycarbonyl; R2 is H, a (substd.) alkylcarbonyl, a (substd.) aralkylcarbonyl, a (substd.) arylcarbonyl, or a (substd.) alkoxycarbonyl; and R3 is H or a lower alkyl]}. The compd. has a relatively low ultraviolet-absorbing capability in the normal state; however, when thermally treated it becomes capable of functioning as an ultraviolet absorber.  Therefore, a film formed from the comps. and not thermally treated allows ultraviolet rays to sufficiently reach its depth and thereby is cured to the depth at the step of image formation, and the succeeding heat treatment increases the ultraviolet-absorbing capability of the film, thus enabling the image formation.

Abstract: PROBLEM TO BE SOLVED: To provide a countenance simulation method which realizes an optical simulation such as make-up without a change in the three-dimensional spatial coordinate and is used as a communication tool by indexing a change in coordinates of parts of a living body in a 3D conformation. SOLUTION: A machine is used to measure a change in coordinates in a 3D conformation based on a Moire fringes method using a point light source and diffraction grating. A certain countenance has three-dimensional change according to a specified rule, for example, when a person has a smile in his/her face, his/her cheeks rise. When a person becomes angry, a part between the brows and the corners of the mouth rise. An optical effect such as a make-up simulates these countenances. A three-dimensional image imitating a smile is created using a color graduation, that is, a make-up is performed by simulating an optical change caused by a three-dimensional change in countenances.

Title: Circuit with phase locking loop
Inventor: SEODORUSU HERARUDASU YOHANESU
IPC: H03D3/24
Filed: 1987-07-15
Abstract: The arrangement with a phase-locked loop PLL (11) having an output (17) coupled to an input (23) of a hold circuit (24) also comprises detection means (27) for detecting an instantaneous interference (Fig. 4b) in the signal present at the input (10) of the PLL (11) and for subsequently generating a control signal (Fig. 4e) which is applied to a control input (29) of the hold circuit (24). The hold circuit (24) is adapted to retain the signal applied to its input (23) during the time interval (T3) when the control signal is presented to its control input (29). The detection means (27) are adapted to determine a phase-lock error between the signal at the input (10) of the PLL (11) and the signal at the output (20) of the voltage-controlled oscillator VCO (19) associated with the PLL (11) and to generate the control signal if the phase-lock error exceeds a given value, for example, 45 DEG . A better detection of the instantaneous interferences can be realised with such an arrangement, rather than if the amplitude information (if present) of the signal at the input (10) of the PLL (11) had been used.
