Title: Device and method for detecting moving obstacle
Inventor: ONOGUCHI KAZUNORI
IPC: B60W30/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To precisely find the position and moving direction of the moving obstacle in the space before it by finding an area other than a movable space outputted by a movable space extraction part and the intersection part of the obstacle, and finding the position and direction of the obstacle. SOLUTION: A moving obstacle extraction part 1 of the moving obstacle detecting device extracts a moving obstacle area. The movable space extraction part 2 extracts a movable space where the obstacle is absent. Then a moving obstacle position and direction calculation part 3 finds the intersection of the presence direction of the moving obstacle and the area other than the movable space to calculate the position and direction of the moving obstacle. In this case, a body which touches a road surface or floor surface like a human, a moving vehicle, and a bicycle is assumed as the moving obstacle, but this device and method are applicable to even an obstacle floating in the air when its height is already known. Consequently, the position and moving direction of the moving obstacle in the space in front of it can precisely be found.

Title: Iron-base nano-crystal magnetic powder, its production, and radio wave noise inhibiting member using the same
Inventor: SUNAKAWA ATSUSHI
IPC: B22F1/02
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic-wave inhibiting member of new constitution, capable of exhibiting a sufficient electromagnetic-wave noise absorbing effect.

Title: Method of deodorization for open-type oil stove
Inventor: HAYATA TERUNOBU
IPC: F23D3/02
Filed: 1979-06-04
Abstract: PURPOSE: To reduce the production of malodorous gas in ignition and in fire extinguishment, by using a heater to heat the vicinity of a wick at 150°C or more before or just after the ignition, providing a heat accumulator over the wick and heating the accumulator to a high temperature during stationary combustion.  
     CONSTITUTION: A coiled heater having the same shape as a circular wick is placed at a height of 3mm from the wick. A heat accumulator having a honeycomb shape is placed at a height of 50mm from a radiation net surrounding the heater. As a result, the vicinity of the wick is quickly heated to 200°C simultaneously with ignition on the wick. A complete combustion temperature is reached in a short time after the ignition on the wick. Since the heat accumulator is heated to a high temperature by stationary combustion, the accumulator is kept at 400W600°C even after fire is extinguished from the wick. When malodorous gas produced at the time of the fire extinguishment comes into contact with the heat accumulator, the gas is burned again. The production of the malodorous gas is thus greatly reduced.

Title: Data identification circuit
Inventor: AOYAMA HIDEJI
IPC: H04B10/2507
Filed: 1988-03-24
Abstract: PURPOSE:To accurately identify data by controlling respective first and second threshold levels of first and second identification circuits (identifiers) to optimum values when a means value and an intermediate value fluctuate due to the deterioration of the S/N of a received waveform. CONSTITUTION:A limiter 57 limits the change width of the first and the second threshold levels Vth1 and Vth2 in upper-limits and lower-limits with a certain margin by an output from a computing element 56, and prevents first and second identifiers 3 and 7 from errorneously outputting data when the upper limit value and the lower limit value of an equivalent waveform from an equalizer 2 exist in an area totally apart from the threshold levels Vth1 and Vth2. When the mean value and the intermediate value fluctuate due to the deterioration of the S/N of the equivalent waveform, the threshold levels Vth1 and Vth2 can be controlled to the optimum values. Thus, data can accurately be identified.

Title: Lighting material of rigid vinyl chloride resin
Inventor: TAKASHIMA KUNIO
IPC: C09K21/12
Filed: 1988-03-23
Abstract: PURPOSE:To obtain a lighting material which is excellent in flame retardancy and light transmittance and does not sag when it is supported by beams, by mixing a post-chlorinated polyvinyl chloride resin with a stabilizer and a specified flame retardant. CONSTITUTION:This lighting material comprises a rigid sheetlike molding of a composition formed by mixing a post-chlorinated polyvinyl chloride resin with a stabilizer and a flame retardant selected from among phosphorus- containing flame retardants and chlorinated paraffins and brominated flame retardants and antimony oxide. This lighting material can retain its sufficiently practical heat distortion temperature even when it contains, for example, a liquid flame retardant or a liquid stabilizer such as DOP. It is controlled in a decrease in a heat distortion temperature, and can contain a larger amount of a flame retardant, so that its flame retardancy can be markedly improved. It is very easy to raise its heat distortion temperature to 70 deg.C or above. When the material has such a high heat distortion temperature, it scarcely sags throughout the year even when it is in the form a rigid sheetlike molding and supported by beams of a span in the range of 670-800mm.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform copying operation by moving an original placing plate upward in the case of copying material to be copied and turning over pages by moving the original placing plate downward after reading a paper surface copied by a scanner and performing copying. SOLUTION: The paper surface of the material to be copied is placed facing upward on the original placing plate 14 positioned at the lower side of a transparent plate 11, and necessary cloying pages are turned over by a page turning mechanism 23. Then, a cloying paper surface is closely stuck at the transparent plate 11 by moving the original placing plate 14 upward by a jack 150 which is an elevating/lowering mechanism, and the display state of a paper surface is read by the scanner 16 linked with a light source 12. When reading and copying are finished, a new copying page is turned by the page turning mechanism 23 after moving the original placing plate 14 downward. Then, the copying paper surface is closely stuck at the transparent plate 11 by moving the original placing plate 14 upward again, and the display state of the paper surface is read by the scanner 13.  Thus, different pages are efficiently copied while maintaining the copying paper surface of the material to be copied facing upward.

Title: Combination type magnetic head
Inventor: KANBAYASHI NAOHIKO
IPC: G11B5/265
Filed: 1982-04-27
Abstract: PURPOSE:To reduce the width of a transition section sufficiently in comparison with that of reproduced track, by arranging an erase head at both sides of a recording and reproducing head via a nonmagnetic material, taking the nonmagnetic material as the 1st erase gap and contacting the 2nd erase head of a prescribed shape in a curved shape. CONSTITUTION:A reinforced member 15 made of the nonmagnetic material is bonded to a part of the recording and reproducing head 5. A rear core section 13 is fitted to erase heads 1, 2 at the side and an erase head core 11 is bonded over the erase heads 1 and 2 at both sides in combination separately. Erase coils 14, 12 are mounted on the cores 13, 11. Since the direction of the magnetic flux at a curved link part of erase gaps 7, 8 prolonged laterally with erase gaps 9, 10 in parallel with the magnetic tape running direction at reproduction is different from the direction of the magnetic flux of a reproducing gap 6, the erased magnetic flux gives no interference on the magnetic circuit of the head 5, and the width of the transition section is sufficiently smaller than the erased track width.
