Patent JP-H0522632-A (JP)
Title: Contour correction circuit
Inventor: ARITA EIJI
IPC: H04N5/208
Filed: 1991-07-10
Abstract: PURPOSE:To obtain a contour correction circuit which can correct the luminance signal with a contour signal that is sharper than conventional and has two or more desirable frequency bands. CONSTITUTION:A contour signal generating circuit 20 produces at least one contour signal having a different frequency band from a 1st contour signal produced by a 1st contour signal generating circuit 5. Then the contour signal generated by the circuit 20 is superposed on the gain control DC voltage supplied to a voltage control variable gain amplifier 6 which amplifies the 1st contour signal. The gain of the amplifier 6 is controlled by the superposed voltage signal. Thus the contour signal can correct two or more frequency bands compared with the conventional contour signal that correct only a single frequency band.

Title: Liquid cosmetic
Inventor: OTANI SHIGEKI
IPC: A61K8/00
Filed: 1994-06-29
Abstract: PURPOSE:To obtain the liquid cosmetic good in the extrusion of the cosmetic from a pen point used as a pen type cosmetic tool storing the cosmetic therein, giving coating marks having a masking effect to skin, and having an excellent dispersion stability. CONSTITUTION:The liquid cosmetic comprises at least a coloring agent, a water- soluble organic solvent (e.g. propylene glycol, glycerol), water and hollow resin particles. The hollow resin particles comprise resin particles having each one or several spherical empty pores in the spherical resin, are produced from the homopolymer or copolymer of (meth)acrylic acid, their esters, acrylonitrile, styrene, vinyl acetate, etc., and have a particle diameter of 0.1-30mum, preferably 0.1-2.0mum. The hollow resin particles exist in the cosmetic in a state wherein the space parts are filled with water, and exist in an empty hollow state by the evaporation of the water due to dryness after coated on skin. Thus, light is scattered with the resin layers and air in the hollow parts, and the cosmetic thereby shows a masking effect to give a white color.
Patent JP-H0335697-A (JP)
Title: Loudspeaker
Inventor: ISHIHARA SUMIO
IPC: H04R9/04
Filed: 1989-06-30
Abstract: PURPOSE:To reduce divided resonance and to enable reproducing over a wide range by dividing vibration into two at the center of a plate diaphragm in a lengthwise direction and coupling the plates by an inter-diaphragm edge such as cloth or urethane, etc., thus using these divided two diaphragms as the diaphragm. CONSTITUTION:A plate diaphragm 3 is divided at the center of the lengthwise direction and since the node of the divided resonance is generated in the outer circumference of a voice coil 5, the divided resonance frequency can be forced away to a high range area. Further, since the plate diaphragm 3, where two divided pieces are coupled by an inter-diaphragm edge 4 behaves as one right body concerning a low frequency, the lowest resonance frequency can be kept low. Thus, the wide range reproduction can be realized for a loudspeaker using the plate diaphragm.

Title: Rust preventive treatment of surface of zinc
Inventor: NAKAMURA ITSUSHI
IPC: C23F11/18
Filed: 1988-07-07
Abstract: PURPOSE:To enable rust preventive treatment inhibiting the formation of white rust on the surface of zinc and ensuring high commodity value by bringing the surface of the zinc formed on a metal into contact with a chromic acid soln. having a specified chlorine concn. CONSTITUTION:The surface of zinc formed on the surface of a metal by galvanizing or other method is brought into contact with a chromic acid soln. having >=2.0mg/l chlorine concn. by immersion or other method. The surface of the zinc dissolves by the action of chlorine to generate hydrogen and the chromic acid and is reduced by the hydrogen to form a coating film on the surface of the zinc. The formation of white rust on the surface of the zinc is inhibited by the surface protecting action of the coating film. The pref. concn. of chlorine in the chromic acid soln. is 2.0-10.0mg/l and that of chromic acid is about 3-15mg/l.

Title: Integrated circuit device
Inventor: UORUFUGANGU PURIBIRU
IPC: G11C11/4096
Filed: 1990-06-29
Abstract: PURPOSE: To prevent a high current from flowing through a laser fuse in the application of a control potential by connecting a terminal means to a potential terminal under the use of an electronic circuit. CONSTITUTION: An electronic circuit 2 contains a load element R. The electronic circuit is connected to one supply potential VDD on one hand and connected to a potential terminal fVx as well as to a terminal means PD of a configuration circuit 1. While a control potential Vp is applied to the terminal means PD, an auxiliary potential V1 is equal to the control potential Vp. The load element may be realized, for example, by a transistor connected as ohmic resistance or resistance. As a load resistance R is lower than a load resistance RL, an auxiliary potential V1 is generated having a value slightly different from the supply potential VDD in the normal condition. Thus, no higher current is generated via the terminal PD.

Title: Method of projecting mask pattern
Inventor: MURAYAMA KATSUHIKO
IPC: G03F7/20
Filed: 1994-06-30
Abstract: PURPOSE:To improve the degree of integration by shifting the relative position between a mask pattern and a wafer by the specified value of the mask pattern pitch from the first projection exposure position when using either one mask, and by the specified 7 value when using the other mask, and performing the second and third exposure with half the proper amount of exposure, respectively. CONSTITUTION:A wafer is projected and exposed first with half the amount of proper exposure by a mask board 1. Next, the mask board 1 is shifted +2/3, and the second projection exposure is performed with half the proper amount of exposure. Furthermore, the mask board 1 is shifted -2/3, and the third projection exposure is performed with half the proper amount of exposure. Hereby, for the photoresist on a wafer, only the section being exposed in superposition achieves proper amount of exposure, thus a pattern with a line width L=1/3P is made by the property of nonlinear photoresist. And, island spaces become equal. Accordingly, the degree of integration can be improved substantially.

Title: Window wiper for automobile
Inventor: KONISHI TAKESHI
IPC: B60S1/04
Filed: 1987-07-08
Abstract: PURPOSE:To aim at reduction in a storage space by installing a mechanism, which holds the wiper blade side in a bending state at less than the specified load, in a bendable turning part at an intermediate part of the wiper arm, while installing a stopper, coming into contact with the turning end side of the wiper arm, at the car body side. CONSTITUTION:At time of usual wiping, an intermediate part of a wiper arm 8 comes into a state of being bent by a spring 23 with a caulking pin 14 as the fulcrum shaft. At this time, a wiper blade 11 corresponds to the lower edge of a front window 6 so that enlargement of a wiping area by blade rubber 12 is well promotable. Next, at time of storage, if a retainer 16 at the side of a turning end comes into contact with a stopper 24, movement of the retainer 16 to the more body front side than this stopper 24 is checked, and the wiper arm 9 is oriented to a linear state from the bent state. In consequence, a storage space at time of wiper storage can be made smaller.

Title: Phase synchronizing circuit
Inventor: OSUMI MASAKO
IPC: H03L7/06
Filed: 1988-07-08
Abstract: PURPOSE:To synchronize an analog signal and a sampling signal by a simple circuit by changing a thinning-out interval in a process for bringing a digital code to down-sampling. CONSTITUTION:An A/D encoder 1 inputs an analog signal of 2kHz frequency, brings it to A/D conversion by 1MHz sampling frequency and outputs a digital code, and a digital filter 2 inputs the digital code of 1MHz sampling frequency, and outputs it by eliminating a turn-back component by down-sampling. A thinning-out circuit 3 inputs the output signal of 1MHz sampling frequency of the digital filter 2, thins it out to a signal of 32kHz sampling frequency and outputs it, and also, executes a control of a thinning-out interval. A phase comparator 4 inputs the output signal of the thinning-out circuit, compares phases of the analog signal and the sampling signal, sends a pulse to an Up- signal when the phase of the sampling signal lags, and outputs a pulse to a Down-signal when the phase of the sampling signal leads. In such a way, the analog signal and the sampling can be synchronized.
