Title: Video automatic gain adjusting circuit for video signal circuit including nonlinear element
Inventor: FUKADA JUICHI
IPC: H04N5/208
Filed: 1989-10-19
Abstract: PURPOSE:To adjust an error caused by a nonlinear component by applying a variable offset adjustment voltage to one of a synchronizing signal portion and a back porch portion of a video signal subject to sampling and holding and adjusting the gain of an amplifier so that the voltage difference of the both is substantially zero. CONSTITUTION:A video signal delayed for 1H period is inputted to a variable gain amplifier 20 and amplified at a gain in response to the signal inputted to a control terminal 22. A subtractor 26 outputs a difference between an output of the amplifier 20 and an input video signal 10. The sample-and-hold circuits 42,44 sample and hold the part corresponding to the SYNC tip and the pedestal in the synchronizing signal of the horizontal scanning line in reference to the difference. A differential amplifier 202 receivers an output of the hold circuit 4 and outputs a voltage being a difference from the voltage from a variable DC power supply 206. A comparator circuit 46 give s control signal so that the difference between the output of the hold circuit 44 and the output voltage of the amplifier 202 is substantially zero to the variable gain amplifier 20. The DC power supply 206 adjusts the voltage in response to the nonlinear characteristic of the nonlinear element of the video circuit.

Title: Four-wheel drive vehicle
Inventor: MURAKAMI TAKESHI
IPC: B60K17/348
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To suppress fuel consumption in a straight advance state of the constant velocity of a car, and realize high traveling stability even when a steering wheel is turned with the straight advance state of the constant velocity of the car. SOLUTION: A coupling 20 is controlled so as to adjust a transmitting torque to rear wheels RT3, RT4 to zero when a speed change is small. When it advance almost straightly at a nearly constant speed, fuel consumption is suppressed by eliminating a transmitting loss of power to the rear wheels. On the other hand, when it is judged that a speed difference between right and left wheels is large, the distribution of the transmitting torque to the rear wheels is restarted. Therefore, when a driver changes a lane, it is possible to restart the transmission of power to sub-driving wheels at once to stably make a vehicle travel.

IPC: A43D86/00
Filed: 1990-10-08
Abstract: PURPOSE:To facilitate the bonding process, and to obtain a shoe having solid beauty by bonding an unvulcanized peripheral rubber tape so as to cover the boundary part between the instep cover fitted on a last and the unvulcanized rubber outer bottom part being bonded to the undersurface of the instep cover, and by curing the unvulcanized members by means of heated air. CONSTITUTION:The viscosity of a coloring latex compound is preferably set to be 10000 to 30000cPs in the measuring value by means of a B-type viscometer. As latex, natural rubber latex, styrene-butadiene copolymer rubber latex or the like are used. The solid matter in the coloring latex compound is preferably set to be 45 to 50%. In the coloring latex compound, if scorching is fast, the adhesion of the lower peripheral part of the instep cover to the unvulcanized rubber outer bottom part is impaired, therefore thiuram non-sulfur vulcanized rubber is preferable rather than sulfur vulcanized rubber. Thus, a shoe having a three-dimensional pattern on the surface of the peripheral rubber tape, and having a high merchandising value in which the pattern is not separated from the peripheral rubber tape can be obtained by a relatively simple process.

Title: Production of photocatalyst and its use
Inventor: KOIZUMI SHINICHI
IPC: B01J35/02
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To improve hydrophilicity and to prevent deterioration in stability of properties by preliminarily irradiating a photocatalyst with light of higher intensity than that of the light which induces hydrophilicity to the photocatalyst surface. SOLUTION: The photocatalyst is preliminarily irradiated with light at higher intensity than the intensity of excitation light which induces hydrophilicity when the catalyst is used. For example, if about 0.01 mW/cm2 intensity of the excitation light is to be used, the photocatalyst is preliminarily irradiated with light at about >=0.1 mW/cm2 intensity, which is namely 10 times or more intensity. Thus, highly ampliphilic property can be maintained. For example, the surface of titanium oxide single crystal is irradiated with UV rays at about 40 mW/cm2 intensity and about 300 to 400 nm wavelength by using a mercury xenon lamp. By this method, the contact angle with water decreases with irradiation time, and the surface is changed to be hydrophilic. Thereby, the hydrophilic function of the photocatalyst is improved and its stability can be maintained.
