Filed: 1989-02-22
Abstract: PURPOSE:To prevent drifting of a car from being produced when it travels on rough road by judging traveling conditions using upper and lower accelerations, steering angle, etc., executing alignment control when the car travels on good road in straight forward direction, and stopping the alignment control on the rough road until the rough road is passed, in the above system of a camper, etc. CONSTITUTION:Whether a traveling road is rough or not and whether a traveling direction is straightforward or not are judged by a traveling condition judgement means 2 to which detecting signals are transmitted from an upper and lower G sensor 3, steering angle sensor 4, etc., and judgement results are transmitted to a controller 5. The controller 5 controls an alignment control actuator 1 according to the judgement results. Namely, when the traveling road is in straightforward direction and not rough, alignment control is executed, and when the road is rough, the alignment control is stopped and, after the rough road is passed, it is re-started.

Filed: 1989-02-21
Abstract: PURPOSE:To prevent a channel causing a leakage current from being formed by a method wherein a high-concentration N-type impurity diffusion region is formed in a prescribed part of an N-type epitaxial layer which is situated under an emitter-electrode conductor and which is situated between P-type impurity diffusion regions used as an emitter and a collector. CONSTITUTION:A high-concentration impurity diffusion region 15 is formed in a prescribed part of an N-type epitaxial layer 2 which is situated under an emitter-electrode conductor 6 connected to a P-type impurity diffusion region used as an emitter and which is situated between P-type impurity diffusion regions 3, 4 used as the emitter and a collector. Accordingly, even when a diode is set to a reverse bias state, an inversion state is hard to cause in the N-type impurity diffusion region 15 whose impurity concentration is high. Thereby, a channel is hard to form on the surface of the epitaxial layer 2 sandwiched between the P-type impurity diffusion layers 3, 4; it is possible to prevent a leakage current from being generated.

Filed: 1992-02-28
Abstract: PURPOSE: To carry out mounting at high density by installing a ground plate which is a conductive metal to be installed in both ends of a housing and is electrically connected with a shield case for mounting connectors on a board. CONSTITUTION: A connection terminal 2 is inserted into and fixed in a terminal installation hole of a housing.

Title: Titanium oxide for photocatalyst, and manufacture of the same
Inventor: TAKAOKA YOICHI
IPC: B01J23/74
Filed: 1995-02-07
Abstract: PURPOSE:To improve a photocatalytic function of titanium oxide by incorporating an iron compound in the inside and/or on the surface of titanium oxide particles. CONSTITUTION:A photocatalyst of titanium oxide is used in a state in which an iron compound is incorporated in the inside and/or mounted on the surface of titanium oxide particles. A titanium compound such as titanium sulfate containing an iron compound such as iron oxide and iron hydroxide is hydrolyzed or neutralized in advance to make titanium oxide, which is defloculated by the addition of mineral acid such as nitric acid and hydrochloric acid and hydrothermally treated under pressure to make titanium oxide containing an iron compound. The reason of the improvement in the photocatalytic function by the incorporation of an iron compound into titanium oxide is that the migration of electrons generated by the photo-excitation of titanium oxide to the iron compound is promoted to facilitate the charge separation from positive holes, causing the increase in positive holes participating in a photocatalytic reaction and in the amount of electrons.
