Title: Plate glass on which rough surface is formed and which have stain resistance
Inventor: KURAMASU HARUKI
IPC: C03C17/30
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a plate glass on which a rough surface is formed and which can prevent the adhesion of dusts or facilitate the removal of the adhered dusts, by forming an uneven rough surface on at least one surface of a glare- proof plate glass, specifying the average surface roughness of the rough surface and forming a water-repelling and/or oil-repelling film on the rough surface. SOLUTION: The surface roughness is 0.2-20 μm by JIS B 0601 test method. The rough surface is formed, for example, by grinding the surface with an abrasive, blasting the surface with hard particles, further etching the processed surface with hydrofluoric acid, etc., to form a glossy rough surface, or coating and baking a paste on the rough surface. The paste is obtained by homogeneously dispersing a low melting point glass containing ceramic particles in a dispersing medium. The water-repelling and oil-repelling film is formed, for example, by adding 5 g of isopropyl alcohol to 1 g of peptadecatridecylfluoroalkylsilane, further adding a small amount of a hydrolysis-accelerating agent (nitric acid) to the mixture, coating the obtained liquid on a film, and subsequently heating the coated film at 250 deg.C for 30 min in an electric oven.

Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain a reflection spectrum of a local area by a sample electric field by impressing a bias voltage between a sample and a probe fitted to a displacement element so that the probe can be made to approach the surface of the sample. SOLUTION: A bias voltage of several volts is impressed between a probe 11 fitted to a displacement element 12 for Z movement and a sample 18 by a power source 14 so as to make the element 12 operate and thereby the probe 11 is made to approach the sample 18. A current between the probe 11 and the sample 18 being monitored, on the occasion, the probe 11 is made to approach until a tunnel current flows between the sample 18 and the probe 11. Since the bias voltage is fixed, a distance of 1nm or less is known from the relationship between the value of the voltage impressed on the element 12 and the amplitude of the tunnel current. Thereby making determination of an impressed electric field of the sample, which has been difficult heretofore. On the other hand, light of a light source 15 is made monochromatic by a monochromator 16 and reflected on the surface of the sample 18.  A light- sensitive detector 17 measures the reflected light and a reflection spectrum of a local area by the sample electric field is obtained.

Title: Portable variable radio frequency generator
Inventor: RORENTSUO FUERUNANDESU DE BUER
IPC: F02B3/06
Filed: 1988-07-27
Abstract: PURPOSE: To obtain a lightweight generator by performing 50/60 Hz conversion of the high frequency output from the generator variable depending on the speed thereof. CONSTITUTION: A magnetism generated from a pole 11 induces a weak current in a winding 10 at the time of turning about the core member of a stator 9. The current is recirculated toward the winding of a rotor 1 through a common electronic regulator 17 and the field of the pole 11 is enhanced until a voltage induced in the winding 10 of the stator 9 reaches a predetermined rated level. A regulator 12 sustains an excited state for ensuring that the voltage induced in the winding 10 has the predetermined rated level regardless of charge and speed within some limit, i.e., the operating speed limit of a generator. When the generator is coupled with a prime mover under state, a high frequency current variable depending on the speed of the generator can be generated. The high frequency current is then rectified and converted into a commercial frequency.
