Title: Steroid glycoside and its use
Inventor: KLEMKE RUDOLF ERICH DIPL CHEM
IPC: C07J17/00
Filed: 1995-07-18
Abstract: Novel glycosides, especially steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, hydroxysteryl compounds are glycosylated with tri-O-acyl glucal using molecular iodine as a reaction catalyst. In this method an alcohol or phenol, especially a hydroxy-steroid such as a water-insoluble cholesterol, is glycosylated, such that the glycosylation is performed in a single step. The resulting steryl pyranoside is by oxidation converted to the corresponding 7-ketosteryl di-O-acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-(beta)-hydroxysteryl 2,3-dideoxy-(alpha)-D-erythro-hex-2-enopyranoside. The steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the glycosides in vivo exhibit a selective cell-destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides also possess a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Title: Semiconductor laminated structure
Inventor: NISHI KENICHI
IPC: H01L29/201
Filed: 1988-07-20
Abstract: PURPOSE:To form the title semiconductor laminated structure in high tertiary light non-linear susceptibility and high reproducibility by a method wherein the lattice constant is adjusted by the film thickness of binary compound semiconductor using the strain laid upon semiconductor layers. CONSTITUTION:The title semiconductor laminated structure is composed of a semiconductor multilayer structure laminated on the surface of a semiconductor structure with mirror index indication (hkl) of integer excluding zero in the substrate surface direction. This multilayer structure is composed of a first binary compound semiconductor subjected to compression strain due to the lattice mismatching with the semiconductor substrate and a second binary compound semiconductor subjected to tensile strain due to the same lattice mismatching in the film thickness not exceeding around the mean free stroke of electrons laminated with each other. The compound semiconductor in the mean composition of the multiple layer structure comprising the binary compounds of zinc blend type crystal is lattice-matched with the semiconductor structure. Through these procedures, the optical non-linearity can be enhanced notably by the effect of exciton absorption as well as the effect of inner electric field attaining to high tertiary light non-linear susceptibility.

Title: Speed control device for seek motor in magnetic disc device
Inventor: KONO KEIICHI
IPC: G05D3/12
Filed: 1985-08-20
Abstract: PURPOSE:To minimize the variation of a magnetic head position when the speed is decelerated till prescribed speed by changing the characteristic of reference speed between the position of magnetic head before seek and a position to be sought depending on the distance of them. CONSTITUTION:When a magnetic head 2 is at a position P before seek, distance information DELTAP with a position P0 to be sought is held in a holding circuit 13. When the value DELTAP is large, a characteristic data fi being a large value is outputted from a characteristic data output circuit 14, a large voltage is applied to a reference speed signal generating circuit 50, a reference speed signal V0 has a leading characteristic and the speed of the magnetic head 2 is controlled by using it as an object value at each position. On the other hand, the distance information DELTAP is small, a small characteristic data fj is outputted, a reference speed signal V0 is saturated and the speed of the magnetic head 2 is controlled based on the object value. Thus, even when there is a phase delay to the control of a VCM 1, the variation of the position when the magnetic head 2 reaches a prescribed speed is less.

Filed: 1990-07-09
Abstract: PURPOSE:To obtain an alloy in which the extrusion rate can be increased and the high strength after T4 treatment can combinedly be realized by executing homogenizing treatment to an Al-Cu-Mn alloy having a specified compsn. at a specified relatively low temp.

In the case the homogenizing treating temp. exceeds 470 deg.C or the treating time exceeds 12hr, fine and uniform Mn series and Fe series precipitates can not be formed on the ingot, and at the time of executing high speed extrusion at a low extrusion temp., recrystallization occurs after T4 treatment, so that the improvement of the strength of the alloy can not be attained. On the other hand, in the case of <400 deg.C homogenizing treating temp. and <4hr treating time, the effect of the homogenizing treatment itself is made lost.

Title: Power amplifier
Inventor: MIWA MAKOTO
IPC: H03F3/30
Filed: 1986-08-04
Abstract: PURPOSE:To eliminate an imbalanced waveform and to remarkably decrease distortions by providing a feedback circuit having only the single polarity caused by a single current path and therefore applying feedback to both polarities. CONSTITUTION:The current of a single side is set at zero by the positive and negative polarities of an output signal through a push-pull power amplifying output stage 6. A measuring instrument measures the signal current flowing through the single side of the stage 6. When both input and output signals have negative polarities, an NPN transistor 14 of the stage 6 is cut off and the signal current flows through a current path 12. The signal voltage induced at a resistance 16 is directly fed back to the input of a voltage amplifier 4 with positive polarity. A resistance 13 is prescribed by a curl code, for example, and therefore the feedback value is changed by resistances 16 and 17 in an output mode of the negative polarity to be equal to the feedback value obtained in an output mode of the positive polarity. Thus the negative feedback of fixed value is always secured to attain a power amplifier having decreased distortions.
