Title: 3-aminopyrrolidine derivative and its production
Inventor: IWASAKI FUMISATO
IPC: C07D207/14
Filed: 1995-03-13
Abstract: PURPOSE: To obtain the subject new compound useful as a medicinal intermediate, or a raw material for agrochemicals and organic chemical products. CONSTITUTION: This new compound, a 3-aminopyrrolidine derivative, is expressed by the formula, e.g. 3-amino-1-formylpyrrolidine. The compound of the formula is obtained by reaction of 3-aminopyrrolidine or its mineral acid salt with a formic ester in a solvent (e.g. methanol) at -80 to 5 deg.C for 0.1-60h. The amount of the formic ester to be used is 1.0-1.5 equivalent times the 3- aminopyrrolidine or its mineral acid salt. The compound of the formula, because formyl group lies introduced as the protecting group for the amino group on its 1-site, enables the protecting group to be easily eliminated under basic conditions; therefore clan be used for synthesizing intermediates instable under acidic: conditions or in a hydrogen atmosphere, intended for medicines, agrochemicals and organic chemical products.

Title: Bobbin correcting device
Inventor: KIKKO TERUJI
IPC: B65H75/50
Filed: 1987-03-10
Abstract: PURPOSE:To correct the inside diameter of a bobbin simply and surely by permitting the shift of a bobbin receiving board in the axial direction and the revolution of a rotary shaft, holding a bobbin inserted into a short cylindrical body by a pressing plate, and correcting the inside diameter of the bobbin by a spread tube body having a tapered roller. CONSTITUTION:A bobbin 5 is inserted into a short cylindrical body 22 by shifting a pressing plate 34 rearwardly, and the bobbin 5 is nipped between a turn stop 27 by turning the pressing plate 34, and then a bobbin receiving board 20 is lowered, and then the tapered roller 25 of a spread tube body 23 projects from a retainer 24, and contacts the inside diameter part of the bobbin 5, and presses the bobbin 5. Since a rotary shaft 11 is revolved by the drive of a motor, the tapered roller 25 is frictionally revolved, and at the same time, also the retainer 24 is revolved and lowered, correcting the deformation of the inside diameter part. Therefore, when the spread tube body 23 reaches the lower edge of the inside diameter part of the bobbin 5, the inside diameter part can be perfectly corrected. Therefore, the inside diameter part of the bobbin 5 can be corrected easily, speedily, and surely.

Title: Exhaust gas reflux controller for internal combustion engine
Inventor: TANAKA TOSHIAKI
IPC: F02M25/07
Filed: 1978-05-02
Abstract: PURPOSE: To reduce NOx in exhaust gas by diluting the VC negative pressure with air according to the suction negative-pressure so as to satisfy the demand exhaust gas reflux characteristic according to the operating condition.  
     CONSTITUTION: An EGR control valve 24 in an EGR duct 23 is fed with a signal negative-pressure from a negative-pressure adjusting valve 25 which functions in response to the suction negative pressure, and fed with a negative pressure diluted with air through a duct 34. The opening of the valve 24 is increased as the signal  negative-pressure increases; so that, in low-speed low-load operation such as idling,  the negative-pressure signal at the valve 24 is zero and EGR is not conducted. In  low- or medium-speed low-load operation, the suction negative-pressure on the  downstream of a throttle valve 21 is very large so that an air intake port 33 opens  and the VC negative-pressure is diluted with air. As a result, the signal negative- pressure applied to the valve 24 is nearly equal to atmospheric pressure, EGR is not  concucted, and instability of operating performance is prevented.

Title: Arc detector
Inventor: GOTO MASAHARU
IPC: G01J1/02
Filed: 1992-02-06
Abstract: PURPOSE:To eliminate the particular protection from a Gaussian beam of large power, by setting a hole and tube not more than a cut-off wavelength of a millimeter wave on the beam center axis of a reflector of a beam transmission system, and by detecting the light of arcing. CONSTITUTION:A Gaussian beam of a millimeter wave is reflected by a reflector 1, and transmitted from a millimeter wave generator of a gyrotron, etc., to an experimental nuclear fusion device. When arcing is generated in the direction of the beam center axis 26, the light thereby reaches to a mount 4 through a hole 2 and a tube 3 set along the axis 26, and is given to a detector 12 through an optical fiber 5. The light is transduced into a current signal by a light emitting diode 6 of the detector 12, and amplified by an amplifier 7. When the received signal has a level higher than predetermined, an arc detection signal is outputted by a comparator 8. The millimeter wave entering the hole 2 and the tube 3 is attenuated, because the sizes of the hole 2 and the tube 3 are smaller than the cut-off wavelength of the millimeter wave, and the mount 4 and the optical fiber 5 are protected.
