Patent JP-H05167077-A (JP)
Title: Semiconductor device
Inventor: SUMIDA WATARU
IPC: H01L29/78
Filed: 1991-12-12
Abstract: PURPOSE:To improve current detection accuracy by joinning a current flowing through a current detection transistor and a current flowing through an output transistor by providing a current limiting diffusion layer in the current detection transistor. CONSTITUTION:There is formed a p-type current limiting diffusion layer 1 by doping p-type impurities into an n-type low concentration impurity drain region 7 by a self-alignment process. Hereby, a current flowing through a current detection transistor is prevented from flowing in its lateral direction by the current control diffusion layer 1 and is allowed to flow only in its longitudinal direction, similarly to an output transistor. Hence there is improved a proportional relation between the current flowing through the current detection transistor and that through the output transistor. Thus, the current detection accuracy is improved.

Filed: 1991-10-11
Abstract: PURPOSE:To facilitate the circulation of the blood and smooth wrinkles at a circumocular skin by stimulating the circumocular skin under the application of pressure. CONSTITUTION:An eye refreshing aid 1 has an eye ambience pressing section 2 and an eye periphery pressing section 3 formed around an area coming in contact with a circumocular skin. Also, a recessed section 4 is formed on the aid 1. When the aid 1 is used, the section 2 is fixed in parallel to a lower eyelid and, therefore, the aid 1 can stably be fixed and pressed, thereby strengthening the stimulation of a lower eyelid. The section 3 is fixed and pressed to the medial angle of an eye, a skin below the lower eyelid, an eye corner and a skin below the eye corner in sequence. The recessed section 4 is formed to prevent the unexpected slide of the aid 1 at a fixing and pressing process. When the aid 1 is fixed and pressed to the lower eyelid, the section 2 is fixed and pressed along a direction in parallel thereto. If there is any induration at the lower eyelid, the aid 1 is first fixed and, then, moved lightly right and left before finally fixed and pressed. Thus, the aid 1 is effective to refresh the circumocular skin, and smooth the wrinkles thereof, particularly wrinkles at the eye corner.

Title: Method and apparatus for fractionally determining ketone body
Inventor: UEDA HIDEO
IPC: G01N33/64
Filed: 1994-12-01
Abstract: PURPOSE: To reduce a blood collecting amt. and to reduce the load on a subject by weighing a liquid specimen containing ketone body to heat the same and evaporating and decomposing acetoacetic acid in the specimen to convert the same into acetone and analyzing acetone in the specimen gas. CONSTITUTION: Whole blood immediately after blood-collecting is introduced into the phiological saline soln. held at a predetermined temp. in a thermostatic tank to be mixed therewith while being rotated. Next, the resulting mixture is weighed by a pipette to be injected into a heat block part 4 from the sample injection port 3 of a gas analyser 2. Acetoacetic acid (AcAc) in a liquid sample is decarbonated on the basis of a predetermined reaction formula to be converted into acetone (AC). AC present from the beginning and AC newly generated by conversion are combined to be gasified and the obtained gas is converted into an electric signal proportional to concn. by a chromatographic column 5 and a detector 6. Hydroxybutyric acid (3-OHBA) present in the liquid sample is not decomposed in a degree of heat block concn. and AC is not generated and, therefore, AcAc and 3-OHBA can be fractionated.

Title: Silencing valve
Inventor: MAEDA TAKASHI
IPC: F16D48/02
Filed: 1993-12-27
Abstract: PURPOSE:To prevent the rise of oil temperature by cutting off connection between a first relief circuit and a second relief circuit when the quantity of oil flowing from an oil cooler reaches the specified quantity. CONSTITUTION:With the increase of engine speed, pump discharge is increased, so that oil pressure in an oil passage is slightly intensified by the overriding characteristic of a high pressure relief valve. When the flow of the throttle 14d of a switching valve 14 is increased, differential pressure is generated in front and in the rear of the throttle 14d, and a spool 14a throttles a communicating hole 23e against a spring 14b so as to cut off a first relief circuit and a second relief circuit. With the circuits thus cut off, the fixed flow of oil flowing through a flow control valve 13 flows into the second relief circuit. Oil pressure rises due to the increase of flow, and the whole flow flows in an oil cooler so as to be cooled sufficiently. Oil pressure at the maximum rotating time becomes equal regardless of the on/off state of a silencing valve. Fluctuation is not therefore imparted to clutch capacity.
