Title: Shape measuring apparatus for structure around railroad
Inventor: IWAKE AKIO
IPC: E01B35/00
Filed: 1991-03-26
Abstract: PURPOSE:To obtain an apparatus which can measure the three-dimensional shape of a structure around a railroad such as a tunnel and a bridge on the side along a track. CONSTITUTION:On a dolly 3 running on a track 1, a light source device 4 for emitting radial planar slit light S in a plane which is approximately perpendicular to the track 1 and an image sensing device 5 for picking up a light cutting line C generated at the wall surface of a tunnel 2 are arranged. When the dolly 3 is running on the track 1, the image sensing device 5 continuously picks up the images of the light cutting lines C sequentially. An image processing device 6 obtains the coordinates of the light cutting line on the light cutting images obtained with the image sensing device 5. The coordinates are imparted to a computer 7. In the computer 7, the coodinates of the light cutting line C on the wall surface of the tunnel is computed, and the three-dimensional shape of the wall surface of the tunnel along the track 1 is obtained. In the computer 7, the three-dimensional shape data of the wall surface of the tunnel are compared with the construction gauge data.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To photo-decompose and remove polluted air containing odorous substances and bacteria most efficiently by arranging at least one ultrasonic light source fitted with a cylindrical honeycomb structure in a housing box main body. SOLUTION: In a housing box main body 1, a cylindrical honeycomb structure 2 fitted to contact a rack plate 4 and an ultraviolet light source 3 directly is installed in the lower part.

IPC: G08C25/00
Filed: 1985-03-26
Abstract: PURPOSE:To prevent an over control by the abnormality of a CPU by deciding whether or not a control signal that is sent from the CPU to an adjusting control equipment is transmitted in a pulse-shaped. CONSTITUTION:When an operator controls selectively an equipment 5i, a selection is made on the selection buttons 11 of a control desk and a button corresponding to the equipment 5i is depressed. In such a case, the selecting information of controlled subject equipment 5i is sent to a CPU 22 through a control desk interface 21 and a converted selecting code is read out by an interface for TC 23 and is sent to out to an appropriate TC master station 3i. On the other hand, the TC master station 3i checks whether the sent out selecting code is an error code or a multiplied selection or not and when it is normal, it is transferred to a TC slave station 4i. The TC master station 3i continues to transfer the selecting code to the TC slave station 4i until a selection cancel is requested. The TC slave station 4i, based upon a received selecting information, connects a control line to the controlled subject equipment 5i and also, generates and returns a selection completion signal to the master station 3i.

Abstract: PURPOSE: To make it possible to obtain an excellent thin absorbent material by sufficiently combining ferrite powder of a weight part in a fixed range with iron powder, which does not exceed the weight part of a constant value, corresponding to a frequency to be used.  
     CONSTITUTION: Together with ferrite powder, iron powder is kneaded at the same time with a hardenable binder; the dielectric constant can be increased by the dielectric effect of the iron powder while the thickness is made thin. In this case, the quantity of the ferrite powder to be mixed should be changed within the range from weight parts 5 to 90 and the quantity of the iron powder should be changed from weight parts 1 to 60 corresponding to a frequency to be used, so as to combine the ferrite powder with iron powder by using a sufficient quantity of the binder. Consequently, an excellent thin radio-wave absorbent material can be obtained.

IPC: G11B15/60
Filed: 1979-05-18
Abstract: PURPOSE: To improve working precision by suppressing harmful vibrations of a machine tool in working operation by forming the shape of the tape guide step part for a magnetic tape on the external circumference of a drum by specific lines.  
     CONSTITUTION: In the expansion figure of the shape of guide step part (tape guide) 4 of tape 1 provided to lower fixed cylinder 3 of the head cylinder of VTR, the section of 0°W180° wound with tape 1 is linear. The section of 180°W360° where tape 1 never meets is formed of a modified trapezoid curve where acceleration A varies continuously. As for drum-circumferential coordinates, the secondary differential coefficient is continuous over the entire circumference and when the tape guide is constituted with lines of a shape with different absolute values of the maximum and minimum of the secondary differential coefficient, the acceleration of the cutter holder of the machine tool varies continuously and the maximum value of the absolute value becomes smaller. Therefore, harmful vibrations of the machine tool lessen and the working precision improves. Consequently, the irregularity of reproduced pictures of VTR is reduced.

IPC: G06F11/34
Filed: 1986-03-20
Abstract: PURPOSE:To automatically re-start a processing without the participation of an operator by comparing the generated PER interruption information with the PER information registered beforehand, and re-starting the processing when the compared result is coincident after the prescribed log information is outputted. CONSTITUTION:For example, a task A registers an area P to a PER information memory part 1, and when in the condition of the registration, for example, a task B refers/renews the area P during the execution of the prescribed processing, an interrupting generating part 2 informs the PER information comparing part 3 of an interrupting signal. The PER information memory part 3 receiving this information compares the PER interrupting information receiving the information with the PER information stored into the PER information memory part 1, and when both are coincident, the part outputs the log information as shown in the figure under the interrupted condition. After the output of the log information is completed, the interruption is released and the original processing is restarted. On the other hand, when both are dissident, without outputting the log information, the interruption is released and the original processing is re-started.
