Title: Steam feeding method by accumulator equipped with high temperature water generator
Inventor: UMAGOE ITSUO
IPC: F01K1/16
Filed: 1983-04-15
Abstract: PURPOSE:To enable to obtain a predetermined amount of steam until the time of next usage of steam followed by a usage of steam by a structure wherein a hot water circulating system is formed between an accumulator and a high temperature water generator and yet a control device to control the pressure, temperature, and water level in the accumulator is provided. CONSTITUTION:Water is fed in an accumulator 21, the water level in which is lowered by the usage of a large amount of steam, by sending an ''opening'' signal from a control device 23 to a feed water valve 30 in a feed pipe 26. When the predetermined water level is detected by a water level sensor 27, the valve 30 is closed. Simultaneously with the feeding of water, the fuel valve 29 in a fuel pipe 1 is controlled so as to rasise the pressure and temperature in the accumulator 21 up to set values before next steam supply. When a peak steam usage becomes necessary at a factory 6 using process steam, a pressure valve 28 in open so as to reduce the pressure in the accumulator 21 in order to generate flash steam to supply to the factory 6. Thus, the peak steam usage can be dealt with by annexing a simple and cheap high temperature water generator to the accumulator.

Filed: 1980-05-19
Abstract: PURPOSE:To select materials of a tactile hand of a tactile sensor for wide-range objective materials, by constituting the electronic tactile sensor by a piezoelectric element, the tactile probe which is fixed to the main face of this element and is slender and flexible, and an electrode lead which is fitted to the said piezoelectric element. CONSTITUTION:An electronic tactile sensor consists of a disc-shaped piezoelectric element 1 such as a caramic PZT, a narrow, sharp and flexible tactile probe 2 such  as a piano wire of 0.26phiX80mm. which stands in the center of the face of the element  1 perpendicularly and is fixed by solder or the like, and lead wires 3 which are soldered to both poles of the piezoelectric element 1. The tip 2a of the tactile probe  2 is brought into contact with an object (solid) in gas or liquid. Mechanical energy  generated by this contact is propagated through the tactile probe 2 to vibrate the  piezoelectric element 1, and simultaneously, an electric signal corresponding to the  mechanical signal, namely, a voltage signal is taken out from lead wires 3 of both  poles by energy conversion. As a result, proper materials are selected as those of the  tactile probe for wide-range objetive materials (magnetic substances, metallic insulating materials, etc.), and detection becomes easy.

Title: Structural material for weld joint
Inventor: IDO SHUHEI
IPC: B23K9/02
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent generation of weld defects due to deformation of members by forming a bent part or a thick part at the end of a lower member to be superposed, increasing the rigidity of the lower member and absorbing weld heat at the joined part. SOLUTION: A bent part 3 is formed at the end of a lower one 2 of the members 1, 2 to be lap fillet welded such as aluminum materials. The bent part 3 is such that a part of the member 2 projects downward to form nearly the same thickness as that of the plate member. In arc-welding the members 1, 2, the rigidity of the member 2 increases, suppressing the deformation due to weld heat. In addition, the tip end of the bent part 3 becomes a heat pool, preventing the proximity of the weld zone A from being excessively affected by heat. As a result, no gap is caused at the weld zone A; in other words, no separation is caused between the members 1, 2, enabling sufficient weld metal to be formed at the weld zone A. Incidentally, in place of the bent part 3, a part of the lower member 2 may be protruded downward to form a thick part.

Title: Online measuring method for substance surface property
Inventor: KATAYAMA RYUICHI
IPC: B82B1/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To enable online measurement of a less smooth region by adjusting an illuminating angle of a shed beam to a normal line on a surface of running coated paper for printing and a light reception angle of normally reflected light with respect to a normal line of an object to be measured in a specific range. SOLUTION: Light from a light source 1 is shed with an illuminating light angle of 78 to 85 degrees with respect to a normal line 10 on a surface 11 of an object to be measured with a reflector 2a changed in position and angle as a reflector 2b. In order to apply normally reflected light of 78 to 85 degrees corresponding to each illuminating angle to a condenser lens 4, a reflector 3a is changed in position and angle as a reflector 3b, a light flux is received by a CCD sensor 5, and an intensity distribution 12 of the reflected light is detected and output as an electric signal for measuring surface property of paper.  When the illuminating angle of a light beam with respect to a normal line of the object to be measured is thus made to be 78 degrees or more, a sufficient reflected light amount can be obtained with less smooth coated paper, thereby enabling measurement of brilliance and smoothness. When the illuminating angle exceeds 85 degrees, scattering of the reflected light is remarkable, lowering measuring accuracy.

Title: Underground jacking device and underground jacking method
Inventor: ASHINO KATSUKUNI
IPC: E21D9/06
Filed: 1994-04-04
Abstract: PURPOSE:To make it possible to replace excavation bits on the way of excavation work. CONSTITUTION:An inner pipe 3, which is rotatively driven, is mounted inside a steering pipe 2 which is advancing underground. An inner pipe 11 is fixed with the tip of the inner pipe 3 inside the steering pipe 2. The inner pipe 11 is structurally integrated with an outer pipe 12 by way of a spline structure which comprises a groove and an projection. Both pipes are axially movable within a specified range and united in one piece in the rotary direction. Excavation bits 4 are installed to the tip of the outer pipe 12 in a rocking manner. When driving, if the inner pipe 3 is moved forward, the outer pipe 12 will run into an engagement part 7 of the jack pipe 2 so that it may be fixed. The inner pipe 11 slides forward against the outer pipe 12, thereby pressing the excavation bits 4 and setting the bits at the excavation position in front of the jack pipe 2. The ground is excavated by driving the jack pipe 2, rotating the inner pipe 3 and the excavation bits in front of the jack pipe 2. Even on the way of jacking, if the inner pipe 3 is pulled backward, the excavation bits 4 will be closed so that it may be possible to replace the excavation bits by pulling out from the rear end of the jack pipe 2.
