Title: Method for screen printing of cream solder
Inventor: MIYAHARA SEIICHI
IPC: B41F15/08
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To ensure quality of printing and to improve productivity. SOLUTION: In a method for screen printing of cream solder which prints the cream solder on a base through pattern holes by feeding the cream solder on a mask plate and sliding a squeegee, in an approaching process where the squeegee starts its sliding movement before the pattern holes and reaches actually the pattern holes, the sliding speed of the squeegee is raised up to the highest approaching velocity V1 being higher than the sliding velocity V2 during printing. It is possible thereby to stabilize rolling peoperties of the cream solder before printing is started and to ensure good quality of printing even at high speed printing.

Title: Temperature measuring instrument applying light
Inventor: SANO YASUKAZU
IPC: G01J5/10
Filed: 1987-03-13
Abstract: PURPOSE:To measure a temperature by providing a temperature sensing element which is constituted by connecting a photoconductor for parallel light projection to one end of a transparent body having half-mirrors on both flat and parallel end surfaces and a converging body to the other and a detector and a counting means for transmitted light pulses from a transparent body which are generated by sweeping light with narrow half-value width between specific two wavelengths. CONSTITUTION:The parallel light which has the narrow half-value width of wavelength is made incident on the transparent body (SiO2) 33 from the photoconductor 32 through a half- mirror 34 to cause remarkable interference by multireflection in the transparent body, and the light is projected from the half-mirror on the opposite side. The interference varies greatly with, specially, the length and refractive index of the transparent body 33 and the wavelength of the light, and both the length and refractive index depend greatly upon temperature. When the light is varied by being swept between the specific two wavelengths, the interference state varies and light pulses are obtained. The number of pulses of each sweep has a linear relation with the temperature of the transparent body 33, so the output signal 42 of a photodiode 41 is counted by a counting circuit 43 through an optical fiber 38. A small hole is bored at the place corresponding to the sweep start position of a rotary interference filter 26 and light from a light source 45 is received by the photodiode; and a counting circuit is reset with a signal 47 to count pulses in every sweep, thereby knowing the temperature.

Abstract: PURPOSE:To prevent drop of the ignition output at the time of high speed operation as well as heat emission at the ignition coil at the time of low speed operation by obtaining an ignition signal, which is controlled with its loop angle with respect to the number of revolutions of the engine, from the angle signal. CONSTITUTION:A ripple signal generator 10 changes the charge/discharge characteristic, on the basis of signals about rotational information given by an FV converter 13, so as to emit a ripple signal f1 having a constant amplitude regardless of the revolving speed of the engine. A comparator 12 performs level comparison between the ripple signal f1 and reference voltage f2 and emits a loop angle control signal c. This pulse width becomes wider with rising revolving speed of the engine. The loop angle control signal C1 shall undergo a logical product processing with a costant angle pulse signal a in an AND circuit 2 so as to give output to a switching circuit 3 and thus to generate the ignition voltage. Accordingly the loop angle becomes larger with rising revolving speed of the engine.

IPC: B32B27/30
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To stably exhibit performance of light storage luminophor, high afterglow luminescence and long afterglow time by laminating a vinyl chloride resin sheet containing a specific amount of the luminophor made of strontium aluminate and activator on a base material layer having a whiteness of a specific value or more. SOLUTION: The nightglow luminescent laminate sheet is obtained by laminating a vinyl chloride resin sheet containing 20 to 60wt.% of light storage luminophor made of strontium aluminate and activator on a base material layer having whiteness of 60 or more. If the luminophor is less than 20wt.%, light storage function of the obtained sheet is insufficient, afterglow luminescence is low and a short afterglow time of a product is obtained. Meanwhile, if the content exceeds 60wt.%, in the case of manufacturing the sheet, molding fault occurs, and there is a fear that the sheet is cured, as well as its cost is increased and not preferable in economy. If the whiteness of the layer is less than 60, its afterglow luminescence and time are short and its object is not performed.
