Title: Manufacture of semiconductor device
Inventor: TSUBOSAKI KUNIHIRO
IPC: H01L23/00
Filed: 1977-09-12
Abstract: PURPOSE: To prevent the corrosion of the element wiring and electrode by removing completely the contamination due to the oil or the inorganic ion before sealing, and also to avoid the lowering of the characteristics caused by the inorganic ion.  
     CONSTITUTION: The semiconductor device assembled on the lead frame is cleansed in the Freon vapor bath to remove chiefly the floating matters in the air or the oil strains caused by the worker's hand. Then the inorganic ion contamination is removed through the spray washing with pure water. Immediately the device is soacked into methanol, and then methanol is removed by the Freon vapor. Then the device is sealed with the resin. Thus, the corrosion of the electrode and the wiring can be avoided with no deterioration of the characteristics.

Title: Multicolor developing method for electrostatic recording system
Inventor: KUWABARA SHIGEO
IPC: G03G15/01
Filed: 1981-07-16
Abstract: PURPOSE:To form a picture which is not fogged by the mixing of the three primary colors by developing the picture successively with developing agents with cyani, magneta and yellow hues respectively. CONSTITUTION:If the values of adsorption starting electrostatic latent potential and defined as cyanine (color C) 3<magenta (color M) 1 < yellow (color Y) 2 in respective developing agents, the higher potential shows the lower adsorption, namely, the developing agent with higher adsorption starting electrostatic latent potential is difficult to be adsorbed to the remaining charge on the surface of an already formed picture. When it is supposed that the quantity of the remaining charge after development is constant, fogging is more reduced by the development in the hue order of C3, M1, T2 at least in comparison with the order of Y2, M1, C3. Consequently, the development in the hue order of C3, M1, Y2 forms the most superior picture of 7 hues in comparison with other hue orders.

IPC: G01B11/06
Filed: 1983-06-20
Abstract: PURPOSE:To make it possible to test the thickness of a film simply, by providing a lighting means, which includes a white light source and lights a body under test, and providing a light receiving means, which receives the reflected light or transmitted light from or through the body under test, which is lit by said lighting means and converts the light into electricity. CONSTITUTION:A white light source 12, a light sending fiber 13, and a lens 14 constitute a lighting means. The lens 14, a light receiving fiber 15, and a light receiving element 16 constitute a light receiving means. Namely, the lens 14 belongs to both light receiving and lighting means. The light, which is inputted to the light receiving element 16 is divided. When the light having specified wavelength lambda'1-lambda'2 is inputted into the light receiving element 16, the light receiving element 16 is driven, and the amount of the inputted light is converted into electricity. Therefore, the output of the light receiving element 16 corresponds to the spectral reflectance of a transmitting thin film 11 in the region of the wavelengths lambda'1-lambda'2. Thus, complicated computing circuits and the like are not required, and the film thickness can be simply tested.

Title: Liquid crystal display device
Inventor: OKAMOTO MASAYUKI
IPC: G02F1/1335
Filed: 1984-05-29
Abstract: PURPOSE:To see distinctly a display image from a wide range by seeing the shadow of a liquid crystal on a reflective plate from the direction of the reflection angle when an electric field is applied to the liquid crystal and setting the thickness of a substrate arranged in the reflective plate side to <=0.4mm.. CONSTITUTION:When a voltage is applied across electrodes 4 and 5, liquid crystal molecules 3b in a corresponding part 3c are inclined to substrates 1 and 2. Light L which reaches a polarizing plate 9 through this part 3c does not reach a reflective plate 10 because the direction of polarization is not rotated, and a shadow C of liquid crystal materials 3 of the part 3c is formed on the reflective plate 10. When the reflective plate is seen from the side of a position A in the direction of the reflection angle, the shadow C projected to the reflective plate 10 is seen as a dark display image, and the part to which the electric field is not applied of liquid crystal materials 3 is seen as a bright white ground. When the reflective plate is seen from the side of a position B, the display image and the shadow C are seen double; but if the thickness of a substrate 2 is set to <=0.4mm., the display image is superposed on the shadow and is seen distinctly when the reflective plate 10 is seen from the side of the position B in the direction of the visual angle.
