Publication number: 20130223477Abstract: Disclosed is a container for the thermal analysis of cast iron that enables a reduction in the amount of tellurium used in thermal analysis. By forming a plurality of fine spaces in the interior of a base plate (12) and sidewalls (11), thermal insulating properties are maintained in the base plate (12) and the sidewalls (11) and the temperature of a sample of the cast iron melt placed in the interior of the container (1) is prevented from cooling down. As a result, even if the amount of a sample supplied for thermal analysis is reduced, the speed by which the temperature of the sample drops is suppressed, and a constant temperature is maintained by the heat from the latent heat of solidification. Accordingly, the amount of tellurium used in thermal analysis can be reduced by reducing the amount of the sample supplied for thermal analysis.Type: ApplicationFiled: April 18, 2011Publication date: August 29, 2013Applicant: NISSABU CO., LTD.Inventors: Hidetaka Hiraoka, Yasushi Kubota, Haruo Ishiyama, Noriko Saito, Hirofumi Tabe

Patent number: 8325170Abstract: An occupying area of a digital system signal line driver circuit in an image display device is large and this hinders the miniaturization of the display device. A memory circuit and a D/A converter circuit in the signal line driver circuit are commonly used for n (“n” is a natural number equal to or larger than 2) signal lines. One horizontal scanning period is divided into n periods and the memory circuit and the D/A converter circuit each perform processing for different signal lines during each of the divided periods. Thus, all the signal lines can be driven. Therefore, the number of memory circuits and the number of D/A converter circuits in the signal line driver circuit can be reduced to one n-th in a conventional case.Type: GrantFiled: December 16, 2009Date of Patent: December 4, 2012Assignees: Semiconductor Energy Laboratory Co., Ltd., Sharp Kabushiki KaishaInventors: Yukio Tanaka, Munehiro Azami, Yasushi Kubota, Hajime Washio

Patent number: 7978169Abstract: There are provided: a first logic operation circuit which performs a logic operation using a high-amplitude logic signal; a transmission system having a load capacitance; and a low-voltage signal generator which is a step-down level shifter transforming an incoming high-amplitude logic signal from the first logic operation circuit to a low-amplitude logic signal having a lower amplitude than the high-amplitude logic signal for output to the transmission system. In the configuration, the first logic operation circuit operates based on a high-amplitude logic signal, and is therefore free from malfunctions and performs operations at high speed. Further, the transmission system introducing a load capacitance transmits a low-amplitude logic signal and therefore restrains increases in electric power consumption and occurrence of unnecessary radiation.Type: GrantFiled: February 21, 2008Date of Patent: July 12, 2011Assignee: Sharp Kabushiki KaishaInventors: Hidehiko Yamashita, Hajime Washio, Yasushi Kubota, Graham Andrew Cairns, Michael James Brownlow
