Title: Thermal transfer recording material
Inventor: OKUYAMA TETSUO
IPC: B41M5/44
Filed: 1987-05-29
Abstract: PURPOSE:To transfer favorable images even onto an ordinary paper having a low surface smoothness, by providing a releasable layer comprising a surfactant and a film-forming material comprising a film-forming thermoplastic or thermosetting resin on a sheet-shaped base, and providing a heat-fusible coloring material layer comprising an organic substance melting at a predetermined temperature and a coloring agent on the releasable layer. CONSTITUTION:A thermal transfer recording material comprises a releasable layer provided on a sheet-shaped base, the releasable layer comprising a surfactant and a film-forming material comprising a film-forming thermoplastic or thermosetting resin, and a heat-fusible coloring material layer provided on the releasable layer, the coloring material layer comprising an organic substance melting at a predetermined temperature and a coloring agent. With the releasable layer provided on the base, transferability of the coloring material layer at the time of thermal transfer is enhanced. Though it is advantageous for enhancing the transferability to set the concentration of the surfactant in the releasable layer to be higher, the film-forming properties of the layer is lowered as the concentration of the surfactant is increased. Thus, the releasable layer is composed of 0.1-80% of the surfactant and 20-99.9% of the film-forming material comprising a thermoplastic or thermosetting resin or the like which has a film-forming property, is solid at normal temperature and has a softening point of at least 150 deg.C.

IPC: H01L29/78
Filed: 1988-06-02
Abstract: PURPOSE:To enable large-scale integration and to improve high yield by forming a source line by self-aligning simultaneously when forming a control gate. CONSTITUTION:A polysilicon film 14 and a field oxide film 12 for control gate formation are successively etched using a nitride film 15 and a resist 16 as masks. The nitride film 15 is etched, the polysilicon film 14 is etched using a difference in an etching rate of silicon and polysilicon with a mask of the resist 16, and finally the nitride film 15 and the resist 16 are removed. That is, an edge of the nitride film 15 is located under a word line, and thus only a part of the field oxide film where a source line is formed is etched upon etching for the field oxide film 12 after the patterning of the word line. The scale of integration and yield can be improved in this way.

Abstract: PURPOSE:To facilitate high tone control, to increase a printing speed and to execute tone reproduction with excellent quality even when high-speed driving is executed by providing a recording head and a waveform transformation circuit. CONSTITUTION:Independent pulses are respectively formed as a driving pulse for controlling the tone of one dot by an amplitude modulation part and a pulse width modulation part 11, and the pulse width of the modulation part 11 is changed by changing the pulse width of the amplitude modulation part stepwise as unit pulse width. Then, the N tone control is executed by the amplitude modulation part and the M tone control is executed by the modulation part 11 so as to obtain the NXM tone. Thus, in the case that the identical tone is realized, the driving speed can be made M-fold when N>M is attained and the driving speed can be made N-fold when N<M is attained. Then, the high-speed driving and the high tone reproduction are realized. Therefore, the printing speed is also increased.

Abstract: PURPOSE:To enable high-efficiency and high-accuracy determination of the activity of the title enzyme for clinical diagnosis in hepatopathies by adding 6<4>-O-D-glycosylmaltopentaose to the sample containing alpha-amylase activity and determining the glucose formed by the enzymatic reactions. CONSTITUTION:A mixture of Tris-hydrochloric acid buffer (pH7.5) containing 6<4>-O-D-glycosylmaltopentaose with 100mM calcium chloride is added to a sample containing alpha-amylase activity to effect the reaction at 40 deg.C for 5.0 hours. Then, the reaction mixture is boiled for 5 minutes to stop the reaction by inactivation of the enzyme. The free glucose in the reaction mixture formed by the enzymatic reaction is determined by allowing glucose oxidase to act on the mixture, decomposing the formed hydrogen peroxide with peroxidase to color the phenol and 4-aminoantipyrine and measuring the light absorption spectrophotometrically. Then, the calibration curve drawn with the values obtained from the known samples is used to determine the alpha-amylase activity.

Title: Plasma etching system
Inventor: IMAHASHI KAZUNARI
IPC: H01L21/302
Filed: 1992-04-28
Abstract: PURPOSE:To sustain constant plasma state or set an optimal plasma state based on the spectral intensity of plasma. CONSTITUTION:In an electronic cyclotron resonance type etching system, plasma generated in a plasma generating chamber 10 is introduced through a detection window 60 and a lens 62 into first and second spectroscopes 64, 66. Spectral intensity is then measured at two wavelength for such gas as Ar having no dependency on the proceeding of etching. When the ratio between two spectral intensities thus measured is set constant, average temperature of electrons in the plasma generating chamber 10 is kept substantially constant thus sustaining a substantially constant plasma state. Upon fluctuation of the ratio between two spectral intensities, values of currents to be fed to coils 44, 54 are varied and the ratio between two spectral intensities is controlled to a substantially constant level.

Title: Optical system for reproducing magneto-optical recording information

IPC: G02B27/28
Filed: 1986-06-13
Abstract: PURPOSE:To reduce number of components and adjusting points by emitting two polarized luminous fluxes split by a thin film polarized beam splitter in the same direction so as to integrate two photodetectors. CONSTITUTION:A horizontal linearly polarized light 2 emitted from a semiconductor laser 1 is emitted onto a vertical magnetization film 7 of a disk 6. The reflected light 8 is reflected on a half prism 4 and its reflected light 9 is made incident in the polarized beam splitter 10. The incident light is split point P polarized light 20 and S polarized light 21 by the thin film deflection split face 16. The S polarized light 21 is reflected further by the reflecting face 19 and emitted in the same direction as the P polarized light 20. The deflected direction of the light 9 is that the P polarized light component in the P polarized light 20 is increased in a region having no information recording, conversely the S polarized light component of the S polarized light 20 is increased in the information recording region. Then the difference of the output between the photodetector elements 12a and 12b of the photodetector 12 is taken by a differential circuit 13 to obtain a reproducing signal 14. Through the constitution above, the elements 12a, 12b are integrated and number of components is reduced.

Title: Press mold for disk
Inventor: SASAKI TOMIYA
IPC: B29C43/52
Filed: 1983-07-27
Abstract: PURPOSE:To equalize quickly the temperature distribution on a stamper fitted surface by a structure wherein the thickness between the stamper fitted surface and a heating and cooling part is thick on external circumference and thin on internal circumference. CONSTITUTION:In a heating time steam 11 comes in from an inlet 14. The steam is discharged to an outlet 13 through a groove 10 transferring heat to a mold plate 15. If the thickness of a stamper fitted surface 8 and the thickness of the external circumference of the surface opposite to the stamper fitted surface are made thicker than the thickness of the internal circumference thereof, the thermal conductance becomes smaller and heated faster in the internal circumference than in the external circumference. In other words, the stamper fitted surface becomes homogeneous quickly. In a cooling time, water 12 rubs heat and advances in the passage direction and like in a heating time, the stamper fitted surface 8 is cooled uniformly. Accordingly, it is possible to solve troubles such as camber etc. of the disk due to residual strain.
