Title: Aminocoumaroneacetic acid ester derivative and its optical resolution
Inventor: SHIMAZAKI TOSHIYUKI
IPC: C07D311/58
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain the subject new derivative capable of readily converted to a compound which is a production intermediate and useful for antithrombocyte, readily purified and good in preservation stability. SOLUTION: This derivative is an aminocoumarone acetate derivative of the formula (R<1> is methyl or ethyl; R<2> is tert-butoxycarbonyl or benzyloxycarbonyl), e.g. methyl 6-(tert-butoxycarbonylamino)coumarone-3-acetate. A racemic body of the derivative is obtained, for example, by simultaneously carrying out hydrogenation and esterification of 6-nitro-4-oxo-3- chromanylideneacetic acid in methanol or ethanol in the presence of an acid by using Pd/C as a catalyst. The optical resolution of the racemic body is effectively carried out by a chiral column chromatography. The derivative of the formula is good in stability and readily purified to the high purity one compared to the one having no amino group.

Title: Controller for hydraulic operation type transmission for vehicle
Inventor: SAKAI TAKAFUMI
IPC: F16H3/08
Filed: 1988-05-21
Abstract: PURPOSE:To suppress the dispersion of the inhibitor car speed due to the oil temperature by allowing the pressurized oil to flow into the second oil chamber of an opening/ closing valve by shifting a servovalve to a retreat position by the oil which passes through the opening/closing valve by the switching to the retreat range of a manual valve. CONSTITUTION:When a manual valve 9 is switched to an R-range from advance, the oil in an oil chamber 22c is discharged through an oil passage L16, and when the governor pressure is that the car speed is over a prescribed value, an opening/ closing valve 22 is closed, and in case of low temperature, the viscosity of the oil increases, and the oil discharge speed from the oil passage L16 lowers, and the switching to the closed position of the opening/closing valve 22 is delayed. However, since a certain time is necessary for the switching of a servovalve 11 to the R-position and the inflow of the oil from an oil passage L18 to an oil chamber 22d, the oil in the oil chamber 22c is perfectly discharged, and the opening/closing valve 22 can be surely switched to the closed position. Therefore, the degree of opening of the valve can be kept at a prescribed value independently of the oil temperature and the inhibitor car speed for suppressing the establishment of a retreat transmission system.

Accordingly, when an MESFET is used by inserting the second source electrodes S2a, S2b onto the insulating films 3, 4 situated between the gate electrodes Ga, Gb and the drain electrode D while the source is grounded, the feedback capacitance between the gate and the source is divided into the capacitance between the gate and the source and the capacitance between the drain and the source; it is possible to eliminate the feedback capacitance substantially. By this setup, the high-frequency gain is greatly enhanced.

Title: Brush for small dc motor
Inventor: TAMURA SHINICHI
IPC: H01R39/18
Filed: 1979-09-28
Abstract: PURPOSE:To give a brush itself a damping effect for vibration, to suppress vibration of a brush and to obtain a secure brush contact by a method wherein a stranded wire section, consisted of fine wires stranded to such a strength than they can be slid with one another, is provided. CONSTITUTION:The coiled section of a brush 3 is consisted of a plurality of fine metal wires stranded and it performs a role which maintains a constant contact stress between a brush and a commutator. At the time when the brush begins to vibrate to a revolving motor, each fine wire of the stranded wire section vibrates and the energy generated by this vibration is changed to thermal energy by one another's rubbing friction. Therefore, vibration of a brush is suppressed and an excellent rectifying function can be obtained without having repetition of a contact and a noncontact states between the brush and the commutator.
