Title: Dental material having faint smell and low irritation
Inventor: YAMAMOTO NAOKI
IPC: A61K6/083
Filed: 1992-08-03
Abstract: PURPOSE:To obtain a dental material having a faint smell, low irritation, low water absorption ratio of polymer, a proper pasty viscous time and extremely high practical value, comprising a specific methacrylic acid ester-based compound. CONSTITUTION:This dental material having a faint smell and low irritation comprises methacrylic acid ester of formula I ((n) is >=2 integer; R is H or methyl) (e.g. compounds of formula II or formula III). The methacrylic acid ester-based compound is preferably blended with a copolymerizable polyfunctional or trimethylolpropane trimethacrylate). Since this curing material has excellent durability in terms of change in dimension, strength, change of color, etc., even under an extremely severe wetness such as interior of oral cavity, the curing material can be used for a long period of time. On the other hand, treatment can be done safely and hygienically by a dentist or a dental mechanic and the curing material has improved operation efficiency.

Title: Color picture tube of color television each dod of which emits multicolors
Inventor: SATO YASUYOSHI
IPC: H01J31/20
Filed: 1987-08-20
Abstract: PURPOSE:To make a color picture tube capable of eliminating a shadow mask, very thin and generating an image of visible color without color dispersion by irradiating electron beams for each of colors from three directions onto a fluorescent screen composed of hemisphere or bowl like dots which are applied separately with fluorescent paints of three elementary colors. CONSTITUTION:Electron guns for red R, green G and blue B each having a deflection yoke are separately provided on a glass body radially from the center of a fluorescent screen 2 in the direction of a constant angle. The fluorescent screen 2 is composed as fluorescent paints of red R, green G and blue B are applied on the surface of a glass base having hemisphere or bowl like dots formed thereon such that a electron gun for only one color irradiates electron beams. This picture tube thus does not need a shadow mask consuming energy and is capable of generating an intense and visible image since the electron guns directly irradiate three-dimensional fluorescent dots to emit multicolors. Furthermore the picture tube can be formed very thin as the electron guns do not protrude backwards.

IPC: B01J3/06
Filed: 1991-07-24
Abstract: PURPOSE:To stabilize the pressure of a sample chamber by introducing two pairs of thermocouples of different types into a superhigh pressure device to be measured, allowing data on temperature detected at the same location to be loaded into a calculation/correction circuit to lead out a signal corresponding to a pressure, and feeding back this signal to a hydraulic control device. CONSTITUTION:Two pairs of thermocouple thermometers of differs types 15 are introduced in the sample chamber 14 of a superhigh pressure device measured to detect temperature at the same location. Next, this detected temperature data is converted to a signal corresponding to a pressure and a temperature at a given time and this signal is introduced into a calculation/correction circuit 16. Next, the signal is led out as a signal which indicates a pressure for constituting a sample, and then is entered to a pressure/temperature indicator 17. The entered signal is compared to a predetermined pressure value 18 to generate a pressure correction signal P', which, in turn, is fed back to a hydraulic control device for pressure control 20 at high temperature and high pressure. Subsequently, a pressure generated in the sample chamber 14 at high temperature is controlled. Thus the pressure generated in the sample chamber 14 can be maintained at a constant level and thereby the reproducibility of synthesis of diamond is exceptionally improved.
