Title: Reading lens system switching original reading density and original reader
Inventor: KANOSHIMA YUUICHIROU
IPC: H04N1/04
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To form an image each density of which is satisfactory on the photodetective face of a solid-state image pickup element by providing a lens for reading reference and a converter lens so as to switch reading density to reference reading density or high reading density. SOLUTION: A reading lens system is in the state of adding the converter lens 22 to the lens for reading reference 20. In this case, as the converter lens 22 'does not vary the distance of an image at the time of reading an original by only the lens for reading reference 20', a distance between the lens 20 and a line CCD 24 is fixed. At the time of reading by reference reading density, the converter lens 22 is saved to the outside of an image forming optical path to image-form the original on the photodetective face of the line CCD 24 only by the lens 20. As 'object distance' varies with this switching of reading density, 'the variation of an object distance' is adjusted by changing the home positions of second and third mirrors 16 and 18 each time of switching reading density.

Title: Eddy current generating device
Inventor: HATTORI HIDEMI
IPC: F27B14/14
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To suppress the overheating of the shell of a crucible to heat the shell by inducing an eddy current to the shell by a method wherein a laterally long slit is formed in the surface opposite to an eddy current generating device, of the shell to support a crucible on the outer peripheral side. SOLUTION: A communication furnace 3 communicating with the meeting chamber of a reflection furnace is arranged on the outside diameter side of a crucible 2 formed of refractories, and an eddy-current generating device 5 to exert a moving magnetic field on the internal part of the crucible 2 is arranged on the outer peripheral side of the crucible 2. Further, a plurality of lateral slits 9a are formed in a shell 9 to suppress thermal expansion of the refractory, and the shell 9 is cooled by a blast duct 10.  When a moving magnetic field generated by the eddy current generating device 5 passes through the shell 9, and acts on the internal part of the crucible 2, an eddy current flowing around the slit 9a is generated in the shell 9 to heat the shell 9, but by supplying cooling air through a blast duct 10, the shell is cooled and temperature is prevented from increasing to a value higher than a given temperature. This constitution reduces the generation of heat at the shell, and produces an energy- saving effect.

Title: Gas meter
Inventor: SATO SHINICHI
IPC: G01F1/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To provide a gas meter which prevents a gas flow passage from being mistakenly shut off even if gas combustion equipment is used continuously for a long time and this is regarded as an abnormal condition such as the leakage of gas. SOLUTION: A gas meter has a weighing mechanism part 100 which outputs a flow signal proportional to gas flow, a microphone 110 which detects the sound of gas combustion in gas equipment, a shutoff valve 140 which can shut off a gas flow passage in the gas meter, and a control part 160 for controlling the entire gas meter. When the gas flow is not smaller than a predetermined value and the sound of gas combustion is detected by a gas combustion sound detecting part 164, then the valve opening/closing control part 161 of the control part 160 immediately drives the shutoff valve 140 to shut off the gas flow passage. When the gas flow rate is less than the predetermined value, the corresponding time over which the gas meter is continuously usable is acquired not by detecting the sound of gas combustion but by consulting a table for continuously usable times.  The gas flow passage is shut off when the gas flow rate is within a certain range over the time during which the gas meter is usable continuously.
