Title: Cover device for manhole
Inventor: SATOU SHIGEO
IPC: E02D29/14
Filed: 1981-04-06
Abstract: PURPOSE:To prevent the lifting of a manhole cover during an abnormal runoff of water as well as the occurrence of noise caused by water flowing during the usual period of time by providing a valve box below a manhole cover with a water drain space and also attaching an elastic umbrella-shaped valve to the valve box. CONSTITUTION:In a manhole cover 3, latticed water-drain spaces 8 having a large area are formed among iron lattices 6 fixed to the inside of a round frame 7. Also, an elastic umbrella-shaped valve 15 of a synthetic resin is provided in a valve box 9 in such a way as to close a water-passing hole 11. By this, during an abnormal run-off period, like concentrated heavy rain, etc., when water goes  back in a pipe buried underground, collides against the incoming water, and is  discharged from the manhole by a water hammer action, water 22 opens the  valve 15 through a valve piece 18 by its upward pressure, passes through the  valve 15, and is discharged to the ground's surface through the water drain  space 8 of the manhole cover 3. Thus, the lifting of the manhole cover 3 by the  water 22 can be prevented.

Abstract: PURPOSE: To extract samples from a shaft kiln such as a blast furnace by means of a compact apparatus with a small driving force, by taking a probe out of, or putting it into, the furnace body with repeated small advancement and retreat caused by changing operating fluid alternately.  
     CONSTITUTION: In inserting a probe 33 placed outside a furnace body 30 into the furnace body 30, a solenoid valve 59 is first opened so as to short-circuit a changing means 55, and operating fluid is fed through an oil pump 52, solenoid valves 59, 54 to a cylinder 40, and a movable truck 34 is moved in the direction of an arrow a. Then with the solenoid valve 59 closed, the operating fluid is charged to a cylinder 40 by means of a motor 58, a changing means 55. The cylinder 40 extends gradually with continuous repeat of alternate expansion and contraction. Hence the truck 34 advances with repeated advancement and retreat, synchronizing the expansion and contractin of the cylinder 40. Consequently the probe 33 held on the truck 34 is inserted into the furnace body with its resistance against its insertion into furnace body remarkably decreased.

Abstract: PURPOSE: To control the valve lift and valve-opening timing of an internal combustion engine in the manner that they are varied in response to the operating condition of engine, by connecting the support point of a rocker arm to a movable end of another rocker arm driven by another cam, as different from conventional arrangements in which the support point has been fixed, and restricting the shifting of the support point by a stopper depending on the operating condition of engine.  
     CONSTITUTION: The valve lifting mechanism of this invention is arranged such that support point 14 of the first rocker arm 13 driven by the first cam 11 for driving valve 12 is fixed to one end of the second rocker arm 16 which is held in contact with the second cam 15 at the other end and driven by the same, and a stopper 17 is placed in contact with the second rocker arm 16 so as to restrict the maximum stroke of the shifting of support point 14 depending on the operating condition of engine. With such an arrangement, the valve lift and valve-opening timing can be controlled in the manner that they are varied in response to the operating condition of engine, so that it is enabled to stabilize idling operation, to save fuel consumption and to increase the output of engine at the time of low-speed operation with the throttle valve being fully opened and also at the time of high-speed operation.

Filed: 1982-03-30
Abstract: PURPOSE:To prevent welding defects, more particularly, slag inclusion effectively in submerged arc welding, by controlling the standard deviation value of the reignition voltage of each electrode at a prescribed value or below. CONSTITUTION:The standard deviation value with respect to the reignition voltage of each electrode is controlled to <=10V in multielectrode submerged arc welding (SAW) whereby the defect such as slag inclusion is prevented extremely effectively. The means for controlling the standard deviation value to <=10V is as follows: The distance between each electrode is required to be set as small as <=25mm., more particularly about 10-20mm.. It is also necessary to decrease the amt. of the fine powder in a flux. More specifically, the amt. of the fine powder of <=(250-300) meshes in particular is kept at <=(10-20)%.

Abstract: PURPOSE:To reduce a fluctuation of a threshold value for doing without any adjustments of a reference voltage to be applied to a gate of a transistor by using a surface channel-type MOS transistor as a signal charge detector. CONSTITUTION:On one and the same semiconductor substrate, a signal charge transfer section, a signal charge detector and a signal charge discharger are installed. At this time, the signal charge detector is made up of a surface channel-type MOS transistor. The surface channel-type MOS transistor is a p-type silicon substrate 1 on which an n-type area 2 and an n-type area 3 are formed as a source A and a drain C respectively with a p-type threshold value control area 4 formed between the source and the drain on the surface of the silicon substrate 1. Gate electrodes 6 are formed as gates B and D above the threshold value control area 4 and an n-type buried channel 5 which is connected to the n-type area 2 working as the source A. Consequently, a fluctuating of a threshold value of the transistor functioning as the signal charge detector gets smaller, resulting in no requirement of adjustments of a reference voltage to be applied to the gate B.

Abstract: PURPOSE:To select a communication terminal equipment close to an incoming call disable terminal equipment as a deputy communication terminal equipment by allowing the incoming call disable terminal equipment to send a weak electromagnetic wave while increasing its output level gradually and selecting a communication terminal equipment receiving the wave and returning its attribute information at first as the deputy communication terminal equipment. CONSTITUTION:When a terminal equipment 11 in communication terminal equipments 11-14 of an exchange 10 cannot reply an incoming call from the exchange 10, a control circuit 17 of the terminal equipment 11 sends a weak electromagnetic wave requesting attribute information to other communication terminal equipments while increasing its output gradually. When the scope of the weak electromagnetic wave reaches an arrival range 21, the terminal equipment 12 uses a reception circuit 16 to receive the wave and returns its own attribute information via a control circuit 17 from a transmission circuit 15 while superimposing the information onto the weak electromagnetic wave. The terminal equipment 11 selects the terminal equipment 12 returning the attribute information at first as a deputy communication terminal equipment based on the attribute information returned sequentially from the terminal equipments 12, 13 or the like and makes a request to transfer the arrival of the call to the terminal equipment 12 to the exchange 10. Thus, the terminal equipment close to the disable terminal equipment is selected as the deputy communication terminal equipment.
