Title: Automatic control method applying difference equation
Inventor: MORITA YOSHIO
IPC: G05B11/32
Filed: 1990-09-25
Abstract: PURPOSE:To attain an automatic control method where the signal value is quickly converged to a target level with no overrun by inputting the signal values of plural parameters to a prescribed circuit as the variable or constant members of a difference equation and then inputting the signal value obtained from an arithmetic operation to a control system to apply the automatic control to the signal value. CONSTITUTION:The output of a circuit which performs the arithmetic operations based on a simultaneous or non-simultaneous linear differential equation containing two variables is used as an operating signal which controls a controlled variable. That is, the arithmetic result value obtained from the differential equation is inputted to a control system as an operating signal and the control depending basically on a proportion element is caused. Then the operating signal is converged to '0' or the fixed value with the repetitive operations of the differential equation. Otherwire the operating signal is periodically changed and automatically controlled. For instance, the coefficients a1, a2, b1 and b2 of the variable members are properly selected together with the constant members c1 and c2 in the simultaneous linear equations I and II. So that the variables (x) and (y) are converged to '0' or the fixed value or periodically changed for automatic control. As a result, a control subject is quickly converged to its normal attitude.

Title: Hot water supplying hopper device for hot water supply type bath boiler or the like
Inventor: UEDA JUNICHI
IPC: F24H1/00
Filed: 1985-11-11
Abstract: PURPOSE:To prevent a back flow from occurring when a downward feeding is toped, by providing a hopper comprising a water-pouring port at an upper part thereof, a discharging port at the lower end thereof and an overflow port at a side wall thereof, and providing vertical fins at an outer peripheral part of a nozzle in the hopper. CONSTITUTION:When pouring flow rate is zero, the water level in a bath hot water supplying pipe 9B is equal to that in a bathtub 5, whereas when water is poured, the water level in the pipe 9B becomes lower than that in the bathtub 5 due to the pressure under which water is downward fed into a hopper 11, and a balance is maintained in that condition. When the downward feeding is stopped, the balance is broken, and hot water in the pipe 9B momentarily flows backward. The back flow is promoted by the phenomenon that air supplied through an overflow port 12 is mixed into the hot water to form bubbles, which float up in the pipe 9B to generate a draft force. However, the bubbles are finely divided by vertical fins 20 provided on an outer peripheral surface 19 of a nozzle 16, whereby the draft force is reduced, and a resistance is exerted on the backward flowing hot water itself, so that overflow of the hot water through the overflow port 12 is inhibited.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a detection apparatus by which an object in front of a vehicle on a road, especially on a curve road, can be detected in an early stage by computing the approximate line of the connection of all first-scene-originated density edge points and second-scene- originated density edge points on road-system coordinates. SOLUTION: A first scene which is photographed by a first camera 16b contains a precedent vehicle and the like on a vehicle where the apparatus is mounted running lane at a short distance of 10 to 30m, and its resolution is high. In second scenes which are photographed by a second camera 26b and a third camera 36b , the resolution of a road surface and a vehicle at long distances of 30 to 60m and 60 to 90m is high. Positions of density edge points on both photographed scene screens are converted, by coordinate conversion means 100 to 300, into an identical road-system coordinate position in which the horizontal projection line of respective vehicle front and rear axles is regarded as one axle, and a density edge point distribution on the top view of a road surface is obtained.  A line which approximates the connection of all density edge points originated from both scenes of road-system coordinates is computed 100, and the approximate line of an on-road white line from a short distance up to a long distance is obtained. When the approximate line is used as a reference to set a search region in order to detect a preceding vehicle, an object in front of the vehicle on a road, especially on a curve road, can be detected in an early stage.

Title: Load opening detecting circuit for high side switch
Inventor: KUMAGAI NAOKI
IPC: H03K17/00
Filed: 1988-10-06
Abstract: PURPOSE:To detect an opening of a load even when a power device is in an ON state by always applying a very small AC signal to the load from an oscillating circuit and detecting a variation of a response of an output terminal of the oscillating circuit. CONSTITUTION:An oscillating circuit 10 is an oscillating circuit for oscillating a very small AC signal, and its internal impedance is set higher than a load 3. An output terminal 12 of the oscillating circuit 10 is connected to a terminal of the load 3 through a capacitor 11, and also, connected to a potential detecting circuit 5b in a control circuit 5 by interposing a resistance R between said circuit and a ground. When the load 3 is connected normally, AC power is dissipated by the load 3, therefore, the potential of the output terminal 12 being its response becomes about the ground potential, and it is detected by a potential detecting circuit 5b. In such a way, even in a power supply period of an ON state of a power MOSFET 1 to the load 3, an AC signal being a test signal is always supplied to the load side, therefore, opening/connecting states of the load can be detected irrespective of ON/OFF states.

Title: Manufacture of gas discharge display element
Inventor: YOSHIOKA TOSHIHIRO
IPC: H01J11/22
Filed: 1991-10-01
Abstract: PURPOSE:To lower driving voltage, and improve luminous efficiency and reliability by heightening a secondary electron emission rate of a dielectric to cover an electrode adjacent to a discharge space. CONSTITUTION:An Al electrode 2 is arranged on a glass substrate 1, and an Al2O3 thin film 3 is formed. O2 is introduced into a vacuum evaporator by means of differential exhaust, and a surface layer 4 of an alkaline earth oxide film is formed by 500(nm) at a substrate temperature of 200 deg.C by electron beam heating. Front glasses 6 on which fluophor 5 is applied lastly are stuck together at an interval of 0.5(mm). Next, a discharge element is treated in the vacuum at 400 deg.C for about two hours. After it is cooled down to a room temperature while exhausting the air, mixed gas of He-Xe is filled by about 300 torr as discharge gas 7, and the manufacture is completed. Like this, since vacuum evaporation on the alkaline earth oxide film is carried out while emitting gas or ion from a supply source different from an evaporation source for the substrate or while emitting rare gas ion to the substrate surface in the O2 atmosphere, a secondary electron emission rate of a film forming dielectric can be heightened, driving voltage can be lowered, and both luminous efficiency and reliability can be also improved.
