Title: Filter apparatus using floatable filter material
Inventor: YAMAMOTO KIYOMI
IPC: B01D24/00
Filed: 1986-04-30
Abstract: PURPOSE:To perform washing well within a short time without sending back a large quantity of filtered water at the time of the regeneration of a floatable filter material, by allowing the floatable filter material filling a filter tank to fall and move in the separation tank communicating with the lower part of the filter tank. CONSTITUTION:A filter bed 7 is formed in a filter cylinder 1 provided with a liquid entrance and exit 5 by a floatable granular filter material 8 and a moving screen 3 for preventing the outflow of the filter material 8 free from the inner periphery of the cylinder 1 is allowed to load on the top part of the filter bed 7 by utilizing the buoyancy of the filter material 8. Further, a filter material regenerating and separating tank 2 having an inverted cone shape is constituted so as to be fixed to the lower part of the cylinder 1 in coaxial relation to the cylinder 1. When the filter material 8 is regenerated, said filter material 8 is moved to an up-and-down direction by allowing the liquid level in the filter tank to fall or rise. By this motion, the suspended substance collected and confined between filter material particles is released. Further, filtered water is sent back from the top part and the filter bed 7 can be re-formed while the filter material 8 is washed by flow-down water.

Title: Signal multiplex transmission system
Inventor: TAMURA KIYOSHI
IPC: H04B3/54
Filed: 1986-04-30
Abstract: PURPOSE:To obtain an inexpensive transmission/reception equipment with simple constitution by sending a power of half wave rectification and a pulse group signal while being overlapped without time division. CONSTITUTION:The power is converted into a prescribed voltage by a transformer 1 at a sending station and the voltage is subject half wave rectification by a half wave rectifying means 2 comprising diodes and the result is outputted. A signal such as a control signal B as a pulse group having a different patter from the kind of signal whose peak is less than the that of the power wave A is outputted, for example, three times or over from a signal forming circuit, and the signal is superimposed on the power subject to half wave rectification via a reverse flow preventing diode 3 and the result is outputted. A smoothing circuit 4 at the receiving station smoothes the power wave A, the signal is extracted as the power and the signal B is separated by a capacitor and the signal of the sending station is read depending on the form of pulse group by a signal discrimination circuit (not shown). In such a case, when the pulse group of the same pattern is confirmed continuously for the several number of times, the processing according to the instruction is executed.

Title: Electromagnetic induction heating cooking apparatus
Inventor: NAKAKURA HIROFUMI
IPC: H05B6/12
Filed: 1990-04-17
Abstract: PURPOSE:To make precise temp. sensing even in case the object to be heated has not flat bottom, prevent excessive rise of the temp., and enhance the safety by setting different temp. upper limit values for two thermo-sensitive elements of a temp. sensing device. CONSTITUTION:If a cooking deep pan 5 having a flat bottom configuration is in close contact with a plate 3, there will be no difference in the temps. between thermo-sensitive elements A7, B8. If the pan bottom has irregular form by contrast to cause, for ex., its central part to be out of contact with the plate 3, and the thermo-sensitive element A7 receives heat emitted from a metal plate 6 through the action of an induction heating coil 2 and reaches the set upper limit value quicker. The temp. of the other element B8 rises retardantly because it senses the inner temp. of the cooking pan 5 using the conduction heat given via the plate 3. For these elements A7, B8 different upper limit values are set, and control is made by a control circuit 13 so that supplying the power to the coil 2 will be stopped whichever upper limit value is reached. Thereby object to be heated is prevented from excessive temp. rise even though its bottom is deformed, and accordingly the safety is enhanced.

Abstract: PURPOSE:To reduce an area in a part required for a contact and to simplify a production process by a method wherein a conductive material is formed in a self-aligned manner with reference to a contact hole and is connected to two conductive parts via it. CONSTITUTION:Barrier metal films 17a and 17b are formed, by a sputtering method, on the exposed surface of a source diffusion layer 15 and on the surface of a photoresist pattern 18. At this time, since the thickness of the barrier metal films is extremely thin as compared with the thickness of the photoresist pattern 18, no barrier film is formed on side faces of the photoresist pattern 18. Then, the photoresist pattern 18 is removed by using an organic solvent or the like. At this time, the barrier metal film 17b which has been formed on the surface of the photoresist pattern 18 is removed simultaneously. As a result, a barrier metal layer 17 is formed on the exposed surface of the source diffusion layer 15, i.e. only on the bottom of a contact hole. Then, aluminum or an aluminum alloy is deposited; it is patterned to a prescribed shape; an interconnection layer 16 coming into contact with the surface of the barrier metal layer 17 is formed.

IPC: B60T13/12
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent the load of a pump from increasing and use an engine- driven pump as a hydraulic pressure source for a closed center type hydraulic pressure booster. SOLUTION: When accumulated pressure of an accumulator 11 for operation hydraulic pressure which accumulates operation hydraulic pressure for operating a brake booster 1 is equivalent to or less than a prescribed pressure, a piston 37 is in an inoperative condition, a pressure release valve 43 is closed, and a valve passage 42 and a reservoir connecting hole 41 are shut down. Hydraulic fluid which is discharged from a pump 10 is supplied to the accumulator 11 for operation hydraulic pressure, and the accumulated pressure rises. When the accumulated pressure of an accumulator 11 for operation hydraulic pressure exceeds prescribed pressure, the piston 37 moves to the left against the spring force of a controlling spring 38 by the operation of the accumulated pressure.  Therefore, the pressure release valve 43 is opened, and the valve passage 42 and the reservoir connecting hole 41 are connected. Therefore, the hydraulic fluid discharged from the pump 10 is returned to a reservoir 15, and the pump 10 is kept under no-load operating condition.
