Title: Air bag sheathing device and pipeline laying method using this device
Inventor: WATANABE TAKESHI
IPC: E02D17/08
Filed: 1993-03-03
Abstract: PURPOSE:To reduce the number of worker/and improve the working efficiency by forming an air bag sheathing device of plural air bags made of elastic member having air-tightness and air bag. CONSTITUTION:An air bag sheathing device 1 consists of a long rectangular paralellopiped air bag 1 made of an elastic member having air-tightness, small rectangular parallelopiped air bags 2, 3 fixed to the side surface of the air bag 1, and air charging/discharging means 5, 5a, 5b. A pipeline 7 to be laid is placed on the air bags 2 arranged in an excavated channel 6, and when the air of the air bag 2 is discharged for contraction, the pipeline 7 is lowered by own weight thereof and placed on the air bag 3. The air bag 2 is charged with air immediately, and expanded to prevent a fall of sediment from the upper part of the side wall of the channel 6. The air of the bag 3 is discharged to fall the pipeline 7 to the bottom of the channel 6, and the bag 3 is expanded to lay the pipeline 7 safely. The laying work is thereby facilitated to reduce the number of workers and improve the working efficiency.

Title: Thin film el element
Inventor: KATAYAMA YOSHIROU
IPC: H05B33/22
Filed: 1988-03-18
Abstract: PURPOSE:To prevent a propagation mode breakdown of a thin film EL element and improve the production yield by forming a second insulating layer in a laminated structure in which a silicon oxide layer or a mixture layer of silicon oxide and lead titanate is provided on a lead on a lead titanate layer. CONSTITUTION:In an element provided with a first electrode 12, a first insulating layer 13, an EL layer 14, a second insulating layer 15 and a second electrode 16 on the insulating base plate thereof, the second insulating layer is formed in a laminated structure in which a silicon oxide layer or a mixture layer of silicon oxide and lead titanate is provided on a lead titanate layer. The silicon oxide insulating layer has a high dielectric pressure compared with the lead titanate insulating layer. Thus, when the insulating layer is formed by laminating SiO2 layer or a mixed layer of SiO2 and PbTiO3 on the second lead titanate insulating layer, even if a dielectric breakdown occurs on the lead titanate insulating layer, it is never transmitted to the SiO2 layer thereon. The dielectric breakdown as the whole second insulating layer is reduced, changing the breaking state of the EL element from propagation mode to self heel mode and improving the production yield of the element.

Abstract: PURPOSE:To apply a frequency-modulation to a jamming signal only in a condition wherein the time delay of the jamming signal is larger than the range gate of a radar by adding a circuit for judging the execution or the stopping of the frequency modulation in accordance with the time delay of the jamming signal. CONSTITUTION:A delay time control circuit 3 obtains a delay time to be given to an input pulse signal and feeds signals to a delay circuit 2 and a frequency modulation execution judging circuit 7. The delay circuit 2 feeds a delay signal with the time delay to a path changeover switch 6 in response to the pulse signal inputted from a received signal input terminal 1. On the other hand, the judging circuit 7 outputs a signal (a) to the switch 6 when the delay time to be given to the input signal is larger than the range gate of a radar and otherwise outputs a signal (b). The switch 6 feeds the delay signal to an amplitude modulating circuit 4 in case of the signal (a) or to a jamming signal output terminal 5 in case of the signal (b). The modulation circuit 4 applies a prescribed amplitude modulation to the delay signal in case of the signal (a) and outputs the modulated delay signal to the output terminal 5.

Filed: 1988-03-18
Abstract: PURPOSE:To send a reception error of an optical receiver to an optical transmitter by connecting a reception error detection circuit and a reception error signal circuit input via an interposing wire provided in an optical fiber. CONSTITUTION:When a signal is sent normally from a light emitting element of an optical transmitter 1 to a photodetector of an optical receiver 2 through an optical fiber 3, a reception error detection circuit output 2' in the optical receiver 2 outputs a signal of low state and outputs a high state signal in the reception error state.

Abstract: PURPOSE: To smoothly perform a spin turn by arranging a relief valve in a discharge oil passage, separating left and right clutch bodies from a center gear as a lever is brought down, applying braking force to a wheel shaft inside of turning after it is put in a half clutch condition, and inversely rotating the wheel shaft on the same side. CONSTITUTION: A relief valve 67 whose relief pressure is changed by a lever 68 is arranged in a discharge oil passage 78. A hydraulic clutch body 38 is connected to the discharge oil passage 78 so as to be shoved in after one of left and right clutch bodies 20 and 21 separates from a center gear. When the lever 68 is brought down in the lateral direction from a neutral position, the left and right clutch bodies 20 and 21 separate from the center gear 15.
