Title: Sound signal recorder
Inventor: TAKANO HIROMI
IPC: H04N5/92
Filed: 1986-12-16
Abstract: PURPOSE:To broaden the recording and reproducing band of a sound signal and to reduce quantization noises by executing coding with an ADPCM (adaptive difference PCM) system. CONSTITUTION:The sound signal can be satisfactorily recorded and reproduced on a magnetic tape 2 by executing with the PCM system, but the recording and reproducing band of the sound signal is narrow such as 15.75kHz and the quantization noise becomes large since the sampling frequency in an A/D converter is set in 31.5kHz and one sample is set in 10 pits. Then by executing coding in the ADPCM system, the number of quantization pits can be reduced. Thus, the sampling frequency and the number of the quantization pits in the A/D converter 12 can be made large and the recording and reproducing band of the sound signal can be broadened and also the quantization noises can be reduced.

Title: Cleaning device
Inventor: TAKEDA FUCHIO
IPC: G03G21/00
Filed: 1990-11-05
Abstract: PURPOSE:To enable the surface of a belt to be stably cleaned even with toner having fine grains and improved fluidity by coagulating and increasing the grains of residual toner on an image carrier by means of a toner coagulation means. CONSTITUTION:When the surface of an OPC level 3 of a transfer sheet passes the free end section of a Mylar seal 4, after a toner image is transferred to the sheet via a transfer device equipped with a corona discharge unit laid near a transfer section roller 5, magnetic toner remaining onthe aforesaid surface is attracted due to the magnetic field of a ferrite magnet 8. As a result, the toner stagnates in a wedge-shape region formed with the free end section of the seal 4 and the surface of a belt 3, thereby causing the magnetic coagulation of toner grains. The deposit of the aforesaid stagnating magnetic toner is again carried to the aforesaid wedge-shape region with the travel of the belt 3, grows with magnetic toner stagnated due to the magnetic filed of the magnet 8, and rubs the surface of the belt 3. According to the aforesaid processes, the surface of the belt 3 can be stably cleaned, even with toner having fine grains or improved fluidity.

Title: Method of recovering residual gas in heat accumulation type heat exchanger
Inventor: SHIODA SUSUMU
IPC: F28D20/00
Filed: 1988-11-29
Abstract: PURPOSE:To enable effective recovery of residual gas by a method wherein residual gas in a heat accumulation type heat exchanger is recovered to some extent by means of vacuum discharge, and the still remaining gas is adhered to steam introduced from the outside for recovery. CONSTITUTION:During heating of a heat accumulating substance, combustion gas being heating fluid is introduced through a heating fluid inflow port 3, formed in the upper part of a heat accumulating chamber 2, to the interior of the heat accumulating chamber 2. In a process of heating rare gas, after a high temperature valve 4 is switched to closing, the valve 5 is opened to introduce rare gas, being gas to be heated, to the interior of the heat accumulating chamber 2 through a fluid-to-be-heated inflow port 6 formed in the lower part of a heat accumulation type heat exchanger 1. When heating of the rear gas is completed and rare gas being residual gas to be heated is recovered, after the rear gas is recovered through a vacuum discharge port 9 through vacuum discharge until concentration of the rear gas is reduced to some value, steam is introduced in the heat accumulating chamber 2 through the fluid-to-be-heated inflow port 6, and the residual rare gas is forced to flow to a gas liquid separating device 7 in a way that the steam is accompanied by the residual rear gas. The steam is cooled in the gas liquid separating device 7 and separated from rare gas, and the rare gas is recovered to a recovery tank 8.

Title: Sequence determination for nucleic acid, method and device for detecting single molecule, and sample preparing method
Inventor: ISHIKAWA MITSURU
IPC: C12M1/00
Filed: 1992-11-10
Abstract: PURPOSE:To detect the position of a single molecule by irradiating a local area of a substrate which has a highly specular surface and to which a sample solution of fluorescent molecules is adhered with exciting light and measuring the frequency of occurrence of a fluorescence intensity. CONSTITUTION:After a sample is dissolved in a prescribed solvent and the solution is diluted, the diluted solution is adhered to a substrate 20 in an atomized state and the substrate 20 is naturally dried. A high-purity solvent is used for preparing the solution and the solution is diluted so that the number of molecules which get in an area having an extent nearly equal to the resolution of an optical microscope 42 can become one. Then a luminous area on the substrate 20 is measured while the surface 20 is irradiated with laser light from an exciting light source 30, but the laser light does not get in the visual field of the microscope 42 and the background light becomes extremely small, because the laser light is obliquely made incident to and reflected by the substrate 20. Especially, since the surface of the substrate 20 is finished is a highly specular state and no solvent molecule exists on the surface, the quantity of Raman scattered light becomes smaller and the background light becomes less to such an extent that even fluorescence from one molecule can be caught. Therefore, since a photon counting camera system can measure the intensity of fluorescence and the frequency of occurrence of fluorescence of the intensity at every picture, the position of a single molecule can be detected.
