Title: Kojic acid derivative
Inventor: YANA MASANORI
IPC: A61K8/00
Filed: 1994-11-16
Abstract: PURPOSE: To provide novel kojic acid derivatives with a strong skin whitening effect whose 2-position has been substituted with mono- or dihydroxybenzoic acid.  
     CONSTITUTION: Novel kojic acid derivatives are represented by formula I (wherein R 1  is H or hydroxyl; and R 2  is hydroxyl) and include, e.g. 2-(4- hydroxybenzoyl)oxymethyl-5-hydroxy-4H-pyran-4-one. The compounds of formula I can be obtained by reacting kojic acid of formula II with thionyl chloride in a solvent such as chloroform to obtain 2-chloromethyl-5-hydroxy-4H-pyran-4- one (chlorokojic acid) and then, reacting this chlorokojic acid with a compound of formula IV in an N,N-dimethyl formaldehyde solvent. The compounds of formula I have a strong tyrosinase-inhibiting activity and, at the same time, excellent actions in whitening action, prevention of sunburn, prevention of pigmentation such as chloasma and naevi, anti-oxidant action or the like and thus, can be used in various cosmetics and skin agents for external use having these activities as their objects.

Abstract: PROBLEM TO BE SOLVED: To obtain a thermosensitive recording label which can deal with fast issuing and is advantageous for the cost and suitable for use in a circulation management by successively forming each specified first intermediate layer and second intermediate layer. SOLUTION: This label is produced by successively forming a thermosensitive recording layer, a first intermediate layer containing polyvinylalcohol, a second intermediate layer which is hardened by irradiation of a ionizing radiation-curing compd. with an ionizing radiation, and a release layer on one surface of a supporting body, forming an adhesive layer on the back surface, and then winding the product. By forming the release layer on the specified second intermediate layer, a uniform release layer can be formed with a small amt. of the coating material and good release property can be obtd. Since a linerless thermosensitive label has no release sheet, the adhesive layer touches the release layer on the thermosensitive recording layer face when the label is in a rolled state.  However, by forming the first intermediate layer containing polyvinylalcohol, fog in the thermosensitive recording layer due to influences of the adhesive in the adhesive layer or decrease in the recording density can be prevented.

Title: Solid-state image pickup device
Inventor: KOYAMA HIDETSUGU
IPC: H04N5/372
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To make the amplitude of a reset pulse voltage into low voltage by providing a diode element, which is formed by performing the diode connection of a transistor(TR) in the same element structure as a reset TR, and generating the gate impressed voltage of the reset transistor while using the forward voltage of this diode element. SOLUTION: The diode element is provided by performing the diode connection of a TR 101a in the same element structure of a reset TR 52. When the gate impressed voltage of the reset TR 52 is generated while using the forward voltage of this diode element, since both the TR are the TR in the same configuration formed by the same process, when a channel potential corresponding to the same gate impressed voltage is fluctuated by the dispersion of processes, the channel potentials of these TR 101 and reset TR 52 are fluctuated just for the equal value. Therefore, since the channel potentials of both the TR are always equal, a normal reset operation is always performed and the reset pulse is made into low voltage.
