摘要:
A signal processing unit with reduced power consumption is provided. A transistor in which a channel is formed in an oxide semiconductor is used for a storage circuit included in the signal processing unit, so that data can be held (stored) even while supply of power is stopped. Non-destructive reading can be performed on the data stored in the storage circuit even when supply of power to the signal processing unit is stopped.

To easily detect in a semiconductor device whether a voltage within the specifications of the semiconductor device is obtained. The semiconductor device includes a detecting circuit that detects an output voltage of an inner circuit of the semiconductor device and judges whether the output voltage is within or out of the specifications of the semiconductor device. A signal for determining whether an output voltage is within or out of the specifications is transmitted from the detecting circuit to a digital circuit, and the digital circuit performs or stops circuit operation in accordance with the signal.

A display device in which light leakage in a monitor element portion is prevented without increasing the number of steps and cost is provided. The display device includes a monitor element for suppressing influence on a light-emitting element due to temperature change and change over time and a TFT for driving the monitor element, in which the TFT for driving the monitor element is provided so as not to overlap the monitor element. Furthermore, the display device includes a first light shielding film and a second light shielding film, in which the first light shielding film is provided so as to overlap a first electrode of the monitor element and the second light shielding film is electrically connect to the first light shielding film through a contact hole formed in an interlayer insulating film. The contact hole is formed so as to surround the outer edge of the first electrode of the monitor element.

A refrigerator is divided into a storage compartment and an air duct in a thermal insulating housing. The cold air for use of the thermal exchange with a cooler in the duct circulates in the storage compartment by a fan. The refrigerator has an ultraviolet ray irradiating device capable of irradiating ultraviolet rays. The ultraviolet ray irradiating device is installed at the inflow side of cooler, but separated from the cooler, so that the ultraviolet rays irradiate the duct by the ultraviolet ray irradiating device. Therefore, various germs such as bacteria or molds in the refrigerator can be prevented from growth, and the refrigerator can be deodorized.
摘要:
A cosmetic composition for skin use which comprises urea and a buffer comprising disodium hydrogenphosphate and citric acid or a buffer comprising potassium dihydrogenphosphate and disodium hydrogenphosphate, or both, and a cosmetic composition further comprising allantoin. Notwithstanding inclusion of urea which is useful for preventing rough dry skin and maintaining moisturization, the cosmetic composition does not have problems such as an increase in pH and an odor from ammonia produced by urea during storage for a long period of time.
摘要:
The present invention relates to a process for producing a W/O/W type multiple emulsion using a polyglycerol polyricinolate (i.e. a polyglycerol ester of a polycondensed fatty acid of castor oil).The use of the polyglycerol polyricinolate is effective in increasing the rate of formation of the W/O/W type multiple emulsion remarkably and giving a W/O/W type multiple emulsion which is stable over a long period of time. The W/O/W type multiple emulsion has also an excellent heat stability and is useful for the production of medicines and cosmetics.
摘要:
A stable W/O/W type multiple emulsion containing very fine water droplets and suitable for use in the production of foods, cosmetics and medicines is prepared by using a glycerol unsaturated fatty acid ester as an emulsifier for a W/O emulsion.

摘要:
A process for producing L-tryptophan or a derivative thereof is disclosed, wherein an indole compound is reacted with serine, or with pyruvic acid and ammonium ion, in the presence of a culture or treated culture of a microorganism of genus Aeromonas or genus Klebsiella having the ability to produce L-tryptophan or a derivative thereof from an indole compound and serine, or from an indole compound, pyruvic acid and/or its salt, and ammonium ion.
摘要:
An automatic control system for a ripper used on a construction equipment in which a load detector is provided on the ripper for detecting load acting on the ripper shank and lift cylinders are actuated to automatically raise the shank when overload is applied to the shank during ripping operation. The ripper is also provided with a depth detector for detecting upper and lower limit positions of the shank and the vertical movement of the shank can be limited between the upper and lower limits. When no overload is applied, the shank is maintained at the lower limit position to rip the ground at a predetermined penetration depth.
