Title: Waste acid treatment method
Inventor: KIYOTA MASATO
IPC: C02F11/00
Filed: 2004-05-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a waste acid treatment method which enables a reduction in equipment cost and a running cost, and enables a reduction in environmental pollution.  <P>SOLUTION: Hydraulic material and waste acid are added to weak soil, such as construction-generated soil and construction sludge, and they are agitated and mixed to produce granulated soil. In such a way, addition of the waste acid, which is an industrial waste, can regenerate the weak soil, which has been discarded, as the granulated soil. The treatment cost of the waste acid, which is high up to now, can be reduced. As the waste acid is not subjected to incineration disposal, irritating odors, harmful oxides, and the like are not generated, which prolongs the life of a landfill disposal site insufficient in volume and contributes environmental preservation.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Filed: 2004-05-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a passenger conveyor device capable of inspecting normally the braking function of a brake unit for a driving machine having a V-belt type power transmitting means while the device constitution remains simple.  <P>SOLUTION: The passenger conveyor device is structured so that an inspection control device 24 is operated to energize a motor 3 and de-energize an electromagnet of the brake unit 17 and a reduction gear 17 is driven in the condition with the brake unit 17 being actuated. An inspection display device 26 emits a signal about a failure in the braking function when the output value of a motor rotating speed sensor 16 after the elapse of the specified time from the energization of the motor 3 exceeds the specified value. This may cause generation of an initial period slip etc. in the V-belt type power transmitting means, but after stabilization of the initial period slip, the output value of the motor rotating speed sensor 16 is judged. This allows inspecting normally the braking function of the brake unit 17 with a simple device constitution and also facilitating the measure to a failure in the braking function.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Heat treatment device
Inventor: NOZAKI KIMIHIDE
IPC: H01L21/02
Filed: 2004-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat treatment device capable of detecting the breakage of a substrate upon irradiating light.  <P>SOLUTION: A semiconductor wafer is mounted on a hot plate to effect preliminary heating by the heat treatment device, and thereafter, flash heating is effected by irradiating a flash from a flash lamp. The temperature of the hot plate is measured at this time. When the flash heating treatment is carried out normally, heat energy given to the semiconductor wafer by the flash heating is transmitted to the hot plate and a slight temperature rise can be recognized in the hot plate. On the other hand, when the semiconductor wafer is broken by the flash heating, the wafer is scattered, and therefore, such heat transmission is not generated whereby the temperature rise of the hot plate is not recognized, too. Accordingly, when the temperature rise of the hot plate immediately after the flash heating is not more than a predetermined value, it is determined that the semiconductor wafer has been broken.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a light floor structure with low noise in a constitution of a floor of a railway vehicle.  <P>SOLUTION: Three floors 71, 72, 73 are put on a bogie frame 51 of a vehicle body via a plurality of joists 61. The joists 61 have notches, and insulate vibrations between the bogie frame 51 and the floors 71, 72, 73. A member with an acoustic radiation efficiency smaller than that of the right and left floors 71, 73 is used for a central floor 72 in the width direction of the vehicle body. The floors 71, 72, 73 run along a longitudinal direction of the vehicle. Vibrations transmitted from a bogie portion below the bogie frame are insulated by the joist 61 installed between the floors, so as to reduce solid propagation noises. A floor member 72 with a small acoustic radiation efficiency is placed at the center of the vehicle body with comparatively large vibrations, so as to reduce the solid propagation noises. Because the floor material with a small acoustic radiation efficiency (namely, with a heavy weight) is used only at a portion with big solid propagation noises, the entire structure can be lightened.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
