Title: Elastic caterpillar belt
Inventor: HATANO TSUNEYUKI
IPC: B62D55/253
Filed: 1980-06-30
Abstract: PURPOSE:To completely separate muds interposed between projecting parts and taken up by forming films between adjacent fin-shaped projecting parts. CONSTITUTION:At a grounding position W1, muds S make ingress between lugs 4 and 4 and fin-shaped projections 5 and 5. In a band W2 where the muds are wound around a rolling wheel 9 and convert their direction, the space between the lugs 4 and 4 is enlarged so that the muds held therebetween are exfoliated from the side walls of the lugs and fall by losing their supports. While rubber films 6 extending between the fin-shaped projections 5 and 5 are in a curved state by the infiltration pressure of the muds S in the band of the grounding position W1, the rubber films elongate rectilinearly in the nongrounding position W2. As a result, a force for extruding from the backward is applied to the muds S, and the muds S are positively purgeed from the space between the lugs towards the direction shown by arrow P.

Filed: 1987-04-10
Abstract: PURPOSE:To contrive to miniaturize the shape with simple constitution by providing a T-branch circuit for power distribution and combination and connecting the prescribed position of an inter-stage matching circuit provided corresponding to plural multi-stage FET amplifiers respectively by a resistance circuit. CONSTITUTION:The inputted microwave power is distributed by the input side T-branch circuit 13, matched by inter-stage matching circuits 6a, 6b and amplified by an FET amplifier (FET3a, 3b, 4a, 4b) and synthesized by the output T-branch circuit 14 and the outputted.

Thus, the shape is miniaturized with simple constitution.

Title: Gauge controller for pipe mill
Inventor: KOYAMA MITSURU
IPC: B21B37/18
Filed: 1979-07-13
Abstract: PURPOSE:To minimize the generation of the off-gauge during the rolling work, by installing the gauge detector at the exit of upper and lower rolls, and by actuating the hydraulic jack held in the thrust block when the pipe gauge goes out of the specified limit, and by automatically adjusting the amount of the lead during the rolled material is being pierced. CONSTITUTION:The gauge detector 20 installed at the exit of upper and lower rolls 1, 2, converts wall thickness of the pipe 8 into an electric signal and inputs it to the gauge control arithmetic unit 21 as the feedback. The arithmetic unit 21 compares the output of the detector 20 with the aim gauge value; and if a deviation is found out, the arithmetic unit 21 produces a control signal to control the hydraulic servo- valve 16 held in the hydraulic jack's driving part 100. That is, the supply 17 of the high pressure oil from the oil tank 18 is controlled by the valve 16 and is fed 15 to the hydraulic jack held in the thrust block 5; hereby, the piston 14 is put into the cylinder 13. Following to this, the plug bar attached to the piston 14 is moved to control the amount of the lead. As a result, since the pipe gauge is always continuously detected, and the amount of the lead is instantly adjusted if some deviation is found out, the off-gauge due to the thermal run-down is restricted, and it gives a remarkable effect to improve the product yield and accuracy.

Abstract: PURPOSE:To form a channel stopper of the same width as the width of an opening in an oxidation resisting film, by forming an oxide film mask at the outer surface part of a channel stopper region, and making an impurity-ion implanting region for the channel stopper narrower than the channel stopper region by using the mask. CONSTITUTION:The unnecessary part of an oxide film 61 is removed by anisotropic etching. Then an oxide film mask 6 is formed. Namely, the oxide film mask 6 is deposited on the side wall of an oxide film mask 3 and on the outer part of a channel stopper region C. Then, impurities for a channel stopper, e.g., boron ions for the channel stopper, are implanted into the surface of a pad 2 of the channel stopper which is exposed on the inside of the oxide film mask by an ion implanting method. Thus, a P<+> layer 42 is formed. Then, the oxide film mask 6 is removed by wet etching. Thereafter, a field oxide film 4 having a thickness of about 6,000Angstrom  is formed by a wet oxidation method at, e.g., 900 deg.C. Thus, a channel stopper 51 is completed. In this way, the stopper becomes narrower than the width of a channel stopper 5 formed by conventional technology.

IPC: G11C11/14
Filed: 1980-07-02
Abstract: PURPOSE:To improve the reliability of a device through making a check on errors by adding a counter circuit counting the number of prescribed loops, and a circuit ANDing the output of said circuit with defective loop data, to a control circuit. CONSTITUTION:To a control circuit for a magnetic bubble storage device stored  with data of a defective loop in some area other than a storage area for information on each minor loop, a counter circuit 12 counting the number of prescribed loops and a circuit 13 ANDing the output of the counter circuit with the defective loop data are added. For example, when infomation is written in, the counter 12 counts the output of a shift register 10 and outputs a ''1'' up to the prescribed number of loops or a ''0'' when the count value exceeds it. Therefore, data passed through the AND circuit 13 are written up to the prescribed number in minor loops via a function driver 11, and minor loops exceeding the prescribed number, even when normal ones, are treated as defective ones, so that nothing is written in. In readout operation, if the defective loop data has an error, the control circuit detects it.
