Title: Circuit and method for detecting command
Inventor: OUCHI TETSUYA
IPC: G06F13/00
Filed: 1988-03-09
Abstract: PURPOSE:To improve the efficiency of communication by discriminating data as a command when a carrier detection signal and the detection signal of data and silent state are sequentially introduced to a command discrimination means. CONSTITUTION:Since a CPU inputs a read signal 1 to one input terminal of a NAND gage 333 in a command discrimination circuit when command reading terminates, the output shows zero. FF331 outputs data 1 from an output terminal Q in accordance with the output of the gate 333 and the fall of a clock. Consequently, '1' is inputted to the terminal 2 of an AND gate 341 and data '0' is outputted from the gate 341. Since a command signal is supplied from the command discrimination circuit to the CPU as long as the state is maintained, the CPU recognizes that received data is that except for the command. The output of data '1' is maintained until the surface of a transmission line comes to a silent state and '0' is supplied from a carrier detection part 311 to the reset terminal of FF331.

Title: Magnetic fluid sealing device
Inventor: TAKITA KIYOSHI
IPC: F16J15/43
Filed: 1985-03-19
Abstract: PURPOSE:To permit a device to reset its sealing performance after the pressure of gas abnormally rises, by providing plural streaks of annular protrusions on the internal peripheral surface of a magnet supporting ring which supports bar magnets peripherally arranged in an equal space. CONSTITUTION:A device provides between opposed both end surfaces of magnetic ball blocks 2 a plurality of bar magnets 6 to be arranged in an equal space on the concentric circumference with a rotary shaft. A plurality of streaks of annular protrusions 7b are provided in the internal peripheral surface of a magnet supporting ring 7 supporting the bar magnets 6, and this part of said protrusions provides a labyrinth seal function. In this way, if a leak of gas is started in a magnetic fluid sealing part in generation of an abnormal rise of pressure, the labyrinth part reduces the pressure, and the sealing device, decreasing pressurization to magnetic fluid by the level of this reduction of the pressure, prevents the magnetic fluid from dispersing, enabling sealing performance to be reset.

Title: Suspension control device for wheel type crane
Inventor: SAWAKI MASAHIDE
IPC: B60G17/08
Filed: 1986-03-13
Abstract: PURPOSE:To improve comfort in riding and running stability by constituting the system wherein necessity for rolling prevention is judged through the comparison of vehicle speed and a steering amount with reference values and a suspension lock cylinder is locked depending upon the result of the judgement. CONSTITUTION:When the detected signals of a vehicle speed detector 21 and a steering amount detector 22 have been inputted to a controller 30, this controller 30 makes judgement as to necessity for rolling prevention through comparison with reference vehicle speed and a reference steering amount. When the rolling prevention has been found necessary, a lock signal is outputted to the solenoid 18a of an electromagnetic valve 18. Said lock signal causes the electromagnetic valve 18 to be changed over to a changeover position 'I', thereby prohibiting an oil inflow and outflow between an oil chamber 10a at the head of a cylinder 10 and an oil chamber 10b at the bottom thereof and locking a suspension lock cylinder 10. According to the aforesaid constitution, comfort in riding and running stability can be improved.

Abstract: PURPOSE:To obtain a U-shaped groove isolation formation method, by which a crystal defect is never generated by a method wherein a groove is formed between an element region of the surface of a semiconductor substrate and other element region of the surface, the interior of the groove is filled with a polycrystalline or amorphous silicon layer insulated electrically from the substrate and the surface of the groove is coated with an insulating material film adhered by deposition. CONSTITUTION:A mask is formed on a P-type single crystal Si substrate 1 by a photolithography, an isolation groove is made by a selective ion etching(RIE) method and the surface of this groove is thermally oxidized to form an SiO2 film 2. When a polycrystalline silicon layer 3 is grown by deposition by a reduced CVD method, the deposition is completely proceeded isotropically. Therefore, the groove not only is completely filled but also the final surface of the layer 3 also becomes almost flat. When this layer 3 is etched back by an RIE method, a state that the layer 3 is left only in the groove is obtained. Moreover, an SiO2 layer 4 is applied on the whole surface of the substrate by a CVD method, subsequently, a selective etching is performed by a normal photolithography and an RIE method and an SiO2 layer 4' is left only on the upper part of the groove. Thereby, a U-shaped groove isolation structure is realized.
