Title: Extractive separation of nucleic acid base having amino group and/or its derivative
Inventor: GOTO MASAHIRO
IPC: C07H21/00
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To perform an extractive separation of the subject compound in a high extraction rate, selectively and easily by using a specific diphosphonic acid type-extracting agent, etc., as the extracting agent. SOLUTION: This objective compound is extractively separated by using a diphosphonic acid type-extracting agent of formula I [(n) is a positive integer] (preferably 1,12-dodecanediol-O,O'-diphosphonic acid) or a monophosphonic acid type-extracting agent of formula II [(m) is a positive integer] (preferably phenylphosphonic acid monododecyl ester). In the above extractive separation, e.g. an aqueous solution containing extracted substance is mixed with a water immiscible organic solvent solution of the above extracting agent, left to stand until the mixture exhibits layer separation and making the organic solvent layer to which the above extracted substance transfers into, in contact with e.g. an aqueous solution set at a pH not inducing the extraction for recovering and separating the above extracted substance.  This method is useful for the separation of 5'-guanylic acid from 5'-inosinic acid and/or inosine.

Title: Head mounted finder device
Inventor: TACHIBANA ATSUSHI
IPC: G02B7/28
Filed: 1995-06-14
Abstract: PURPOSE: To eliminate the need of an operation part such as a release button and to provide a compact and inexpensive head mounted finder device excellent in portability by providing the device with a release means releasing a shutter based on a signal outputted from a device for detecting the flicker of eyelid. CONSTITUTION: A line-of-sight sensor 5 detecting the state of eyeballs (the flicker of eyelid) is the release means constituted of a light projection element illuminating the eyeballs or the periphery and a photorecepting element detecting the reflected light. Thus, a mode switching action such as a shutter releasing action or a zoom operating action can be also executed by inputting the line of sight. A camera part 6 is constituted so that the position and the photographing optical axis direction of a camera are precisely adjusted so as to align an unmagnified photographing field with the photographing field of the camera. Besides, a photographing optical system 6a is used as a secondary image forming system and an image is impressed on a film by using two mirrors 6b.  Thus, even in the case of a photographing system requiring long optical path length, a photographing action whose magnification is small (the photographing action of a focal distance corresponding to a standard lens) can be executed by simple constitution.

Title: Judging device for necessity of dredging operation by cutter suction dredger
Inventor: TODA MASAYUKI
IPC: E02F3/90
Filed: 1982-09-29
Abstract: PURPOSE:To easily judge whether or not dredging operation is necessary by a method in which a theoretical sludge content ratio is calculated by signals from a manual input function unit and a sensor unit, and the theoretical sludge content ratio is compared with actually measured sludge content ratio and displayed. CONSTITUTION:From excavated soil thickness T and dredging advancement amount A from a manual input function unit and also a swing speed Vt from a sensor, soil-pumping amount CA=TXAXVt is obtained by the multiplyer of a dredging judger. From the amount CA and inside-dredging pipe flow rate Vdt from the sensor, a theoretical sludge content ratio C=CA/Vdt is obtained by the divider of the dredging judger. The ratio (alpha=Vt/C) of the theoretical sludge content ratio C to actually measured dredging pipe sludge content ratio Vst from the sensor is obtained by the divider. When the ratio alpha is displayed on a displayer CRT for every sampling time, judgement of whether dredging operation is necessary or not is made possible.

Title: Fm code signal demodulating circuit
Inventor: MASAKI MAYUMI
IPC: G11B20/06
Filed: 1984-08-16
Abstract: PURPOSE:To expand a fluctuation allowable range of an FM code signal to maximum and to demodulate it by detecting presence or absence of a level fluctuation in a prescribed period of a sampled FM code signal at a prescribed position. CONSTITUTION:To make a fluctuation allowable range maximum, it is necessary to detect presence or absence of a level change during the period from 0 to 3/4N0 at a 3/4N0 position. An edge signal detected in an edge detecting circuit 3 becomes an FM code signal by a T-FF4 and the detected edge signal sets an RS-FF5. A counter 7 outputs a signal corresponding to a 3/4 position in a data one bit. The sampled FM code signal is inputted to an M0 clock delay circuit 6, impressed to a D-FF8 and on the other hand, the FM code signal sampled at a D-FF4 is impressed to a D-FF9, and both signals are decided for a level by a 0.75 bit outputted from the counter 7 and one bit data are outputted as ''0'' or ''1'' from an output terminal 11.
