Filed: 1979-09-29
Abstract: PURPOSE:To control the dimension of etching material excellently in chemical etching, by detecting the quantity of material to be etched from the change in temp. of etching fluid caused by the dissolution reaction during etching. CONSTITUTION:In performing chemical etching by immersing a material to be etched such as silicon substrate in etching fluid, the change in the temp. of etching fluid caused by dissolution reaction is measured.

Title: Flexible conduit
Inventor: YOSHIMURA SATOSHI
IPC: H02G3/04
Filed: 1992-05-18
Abstract: PURPOSE:To obtain a flexible conduit free from short circuits of the cores of electric wire cables with its metallic wire being damaged on the insulating coatings of the cables, even if it is bent repeatedly, by coating the metallic wire to be wound spirally with an insulating material having a small friction coefficient. CONSTITUTION:Vinyl hexafluoride, etc., for example, having a small friction coefficient and a high corrosion resistance are appropriate as insulating coatings 6 on a metallic wire 1 to be wound spirally. Besides, it becomes possible to widen the movable range and extend application too by forming the insulating coatings 6, if a softer elastic metal material is used as the metallic wire 1 setting more importance on flexibility than corrosion resistance. And friction force by bending becomes small by forming the insulating coatings around the metallic wire wound spirally. And even if wiring cables touch it, it becomes possible to prevent the breaking of the insulating coatings of the wiring cables by bending repeatedly many times. Besides short-circuiting is prevented, even if they are broken.

Title: Thin film field-effect transistor and its manufacture
Inventor: NISHIHARA TOSHIYUKI
IPC: H01L21/336
Filed: 1994-06-07
Abstract: PURPOSE:To prevent the fluctuation of a threshold voltage Vth and the deterioration of a breakdown voltage between a source and a drain which are to be caused by the storage of minority carrier in a channel region, in a thin film field-effect transistor (thin film FET) formed on an SOT substrate. CONSTITUTION:The forbidden bandwidth of a source region is reduced in accordance with the distance further from a channel region. The maximum width of the forbidden band is made smaller than or equal to the forbidden bandwidth BGch of the channel region. In the case of an NMOS-FET, the mobility of holes is increased by the contribution of a drift electric field generated by the inclination of potential in the source region, so that holes H2 generated by collision ionization at the drain end become easy to flow out to the source region. As the result, the hole storage in the channel region is prevented. The inclination of potential can be formed by imparting the horizontal direction concentration distribution of Ge by two-step ion implantation of Ge applying the ordinary LDD process.

Title: Formation of photosensitive resist film on printed wiring board
Inventor: FUJII TASUKU
IPC: H05K3/00
Filed: 1987-05-22
Abstract: PURPOSE:To make a photosensitive resist film, which is sufficient in its adhesion strength and thickness, formable on a conductive surface, by sticking photosensitive powder on the conductive surface and dissolving it. CONSTITUTION:Photosensitive resin powder 6 is stuck and dissolved on a conductive surface. For example, a copper foil 2 and a copper plating layer 3 are piled on a substrate 1 and next they are pre-heated and dried. In succession a fluidization dip coating method, in which the substrite is dipped into resin powder on a fluidized state, is used to stick and dissolve the photosensitive resin powder 6 on the copper plating layer 3 so that a photosensitive resist film is formed. An electrostatic powder coating method, in which the coating film is formed by using electric charges, can be used instead of the fluidization dip coating method. Hence, cost in using chemicals can be decreased, and also a photosensitive film can be formed highly in its precision and sufficiently in its adhesion strength and thickness.
