Filed: 1989-12-01
Abstract: PURPOSE:To easily attach and detach a guide holder and to prevent a fuel rod from breaking by forming the guide for fuel rod insertion of synthetic resin and forming a taper on the insertion side or both sides of its guide hole. CONSTITUTION:The guide 8 for insertion is formed of the synthetic resin and reduced in weight so as to facilitate the attachment to and detachment from the holder 9, and guide holes 16 which are as many as holding holes of a fuel rod spacer 3 are formed at the same positions. The insertion side or both sides of the holes 16 are tapered 17. Then spacers 3 and guides 8 are fixed to the spacer holder 2 and holder 9 and when a fuel rod 14 is fed 13, the fuel rod 14 is guided by the hole 16 of the guide 8 and inserted into the hole of the 1st spacer 3. At this time, the guide 8 is made of synthetic resin and the hole 16 is tapered 17, so the fuel rod is guided smoothly. After the fuel rod 14 is inserted into the spacer 3, the guide 8 is detached, and assembled into the fuel assembly and then moved, and then the next fuel assembly is manufactured, so the guide 8 is mounted on the holder 9 again.

Title: System for compressing voice and thawing it in digital way real-time-wise
Inventor: RONARUDO HENRII JIYOONZU JIYUN
IPC: G10L19/00
Filed: 1994-12-15
Abstract: PURPOSE: To provide a system for compressing and decompressing numerical audio information without any loss. CONSTITUTION: A first audio sample is retrieved from a numerical audio signal, and is entirely stored in a non-compressed form. A second audio sample is retrieved, and a signal difference between the second voice sample and the first sample is calculated. When this difference can be expressed in fewer data segments than would be required to represent the second audio sample, this difference is stored. Otherwise, the second audio sample is stored. In decompressing a compressed data stream, the stored sample is retrieved, and examined whether it is the difference value or a flag value indicating that the following data are a coded amplitude value. When this is the difference value, it is added to the preceding value (taking into account the sign), and the sum is inserted into an output data stream.  This sum is preserved for calculation in case that the next output value is also the difference value. When this is the flag value, it is discarded, and the following sample is extracted and inserted into the output data stream.

Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To make improvements in riding quality by feeding a pump case with oil in an oil reservoir at an expansion stroke at the car height dropping, and also this pump case oil to a high pressure chamber and a high pressure gas storage chamber at a pressure stroke, and then putting the oil in this high pressure gas storage chamber back to the oil reservoir through a control orifice at the time of car height rising. SOLUTION: When a car height goes down, at an expansion stroke by the excitation of a shock absorber, oil in an oil reservoir 1 comes into a pump case 12 via an oil path in a pump rod 9. At a pressure stroke, oil in this pump case 12 is pushed by a lower end of this pump rod 9 and thereby it flows into a high pressure chamber 13b via an oil path 17, and a portion for the volume, a high pressure gas storage chamber 12 is compressed via another high pressure chamber 13a, and the pressure grows higher. Therefore the repulsive force of a piston rod 11 grows larger, and a piston 3 is pushed upward and thus a car height goes up.  In the case of car height going up, oil in the high pressure chamber 13a flows into the oil reservoir 1 through a control orifice 2 and the oil path of the pump rod 9, and a portion for the volume, pressure in the high pressure chamber 13a goes down, whereby the repulsive force of the piston rod 11 is lowered, and thus the car height goes down.

Title: Liquid fuel burner
Inventor: KAMEYAMA SHUJI
IPC: F23D11/00
Filed: 1992-10-27
Abstract: PURPOSE:To perform clean burning by atomizing and supplying liquid fuel, evaporating and vaporizing it to burn it. CONSTITUTION:High concentration vaporized mixture fuel obtained by an evaporating chamber 42 mostly becomes dilute vaporized mixture fuel of a suitable temperature with temperature and concentration regulating air, and is partly fed to a burning unit 47 while it remains high concentration and vaporized mixture fuel. Since burning in the unit 47 is conducted mostly in dilute mixture fuel having not high temperature, a temperature of a flame is low, and discharge quantities of CO, NOx are suppressed. Since the mixture fuel fed to the unit 47 together with the dilute mixture fuel has sufficiently stable burning range for blowing of flame and back fire, the mixture fuel is burned together and hence stable burning range for the blowing of the entire flame and back fire is increased. Thus, clean burning can be conducted.
