Title: Stable ascorbic acid phosphoric acid ester solution
Inventor: SUZUKI ERIKO
IPC: C07F9/09
Filed: 1991-03-13
Abstract: PURPOSE:To obtain the stable title compound solution being a salt of ascorbic acid phosphoric acid ester containing alanine or salt thereof, having excellent physiological action and beautifying effect, capable of being stored for a long period and useful for medicine, cosmetic, etc. CONSTITUTION:1.0g alanine and 30g L-ascorbic acid phosphoric acid ester or salt thereof are dissolved in a distilled water and total amount of the solution is adjusted to 1000ml to provide the stable title ascorbic acid phosphoric acid ester solution. Furthermore, ascorbic acid is used for medicine as oral medicator or external preparation and also blended in cosmetic, because ascorbic acid has excellent physiological action and beautifying effect. Although the solution has a defect causing decomposition and precipitation because of instability of the solution and being difficult to be stored for a long period, addition of a small amount of alanine to the solution improves stability thereof and cause no decomposition and precipitation even in the case of long-term storage.

Title: Controller for power train
IPC: B60W10/10
Filed: 1992-03-30
Abstract: PURPOSE:To reduce the variation of acceleration after the completion of speed change for reducing substantially speed change shocks by previously reducing vehicle acceleration right before the speed change when the throttle opening after the speed change is set to the smaller throttle opening side than that before the speed change. CONSTITUTION:An intake path of an engine is provided with an electric throttle valve connected in series to a mechanical throttle valve to control an intake amount with the electric throttle valve irrespective of a step-on amount of an accelerator pedal. When up-shift is judged, the electric throttle opening is controlled to the side closed by DELTAB. A drive force is reduced by an amount corresponding to the closing amount of the DELTAB right before speed change is substantially started so that the acceleration of a vehicle is reduced by d. When the acceleration of the vehicle is set to (a) after the completion of the speed change, a difference between the acceleration of the vehicle in the start of the speed change and that after the completion of the speed change is only a fall (b) of a gear ratio to substantially reduce speed change shocks.

IPC: G02B6/12
Filed: 1989-03-27
Abstract: PURPOSE:To suppress the absorption loss in a waveguide small by forming an optical waveguide layer of a II-VI compound semiconductor which has a large energy gap. CONSTITUTION:The branch type optical waveguide has a metallic electrode for electrode application at the branch part of the optical waveguide, which has at least clad layers 12 and 14 made of the II-VI compound semiconductor and the optical waveguide layer 13 made of the II-VI compound semiconductor, having a larger refractive index than the clad layers 12 and 14, on a substrate 11 while at least one layer is formed by epitaxial growth. The waveguide layer 13 is formed of the II-VI compound semiconductor layer having the large energy gap, so the wavelength of waveguide light is shortened. Further, the II-VI compound semiconductor has a wide band gap. Consequently, even when light (1mum band) in the same wavelength range as before is guided, the absorption loss in the optical waveguide can be suppressed low.
