Abstract: PURPOSE:To increase the strength of a metal bond to hold super hard polishing powder and to achieve enhancement of the grinding ability, automation and reduction in the consumption of polishing powder in a grinding stone comprising super hard polishing powder of CBN or the like solidified by the metal bond by applying coating layers of ceramics to the super hard polishing powder. CONSTITUTION:A metal bond super hard polishing powder grinding stone comprises super hard polishing powder of CBN or diamond solidified by a bond of metal base. In this case, a coating layer of ceramics is applied to the super hard polishing powder. Also, coating layers the innermost one of which is made from ceramics are applied to the super hard polishing powder. The ceramics is a nitride or a boride. Polishing powder 11 made of e.g. CBN is fixed by a metal bond of Ag or other elements and air holes 13 are provided. The surface of the polishing powder 11 is coated with both a TiN layer 14 of film thickness 1mum and a Ti layer 15 of film thickness 1mum by CVD or PVD method: The strength of the metal bond 12 to hold the polishing powder 11 is thus increased.

Abstract: PURPOSE:To suitably obtain the input and output condition, which is different from an optical input and output condition, by arranging two optical fibers of a fibers of a right angle reflecting mirror at a preset relative position, which is turned 45 degrees from the reflecting plane of a right angle prism, and by turning the total reflecting plane of the reflecting mirror or the prism by 90 degrees. CONSTITUTION:Optical fibers 1, 2, 3 and 4 have preset relative positions. A lens 5 makes the lights emanating from the respective fibers in parallel with each other. The optical fibers are arranged at 45 degrees with respect to the reflecting plane 7 of a right angle prism 6. If a light is guided out of the optical fiber 1, it is guided into the fiber 2 by the total reflection at the prism 6. If the light is quided from the fiber 4 in a similar manner, it is guided into the fiber 3. The prism 6 is turned about its center axis at a right angle with respect to the slope 8 of the prism. If the light is guided from the fiber 1, it is guided out of the fiber 3. Likewise, if the light is guided into the fiber 4, it is guided out of the fiber 2. In these ways, two different optical input and output conditions can be obtained by the rotation of the prism 6 at a right angle so that the optical transduction can be accomplished.

Vertical displacements of the lever 4 are detected with a photoelectrical detector 7, the  outputs whereof are applied via amplifier 8 to a variable frequency oscillator 11. Its output frequency is made higher as the left ene of the lever 4 goes lower. The output pulses of the oscillator 11 are applied to a pulse current generator 13. A fixed amount of charges per input pulse is  supplied to the movable coil 3 to intensify the electromagnetic force being acting in the coil 3,  thereby allowing the left end of the lever 4 to settle in the specified position. The oscillation frequency of the oscillator 11 of this time indicates the weight of the measuring object. A counter  15 counts the output pulses of the oscillator 11 and is reset by the output of a timer 16.

Title: Flame-retarding, transparent polyolefin resin composition
Inventor: SHINGIYOUUCHI KAZUO
IPC: C08J5/18
Filed: 1984-04-09
Abstract: PURPOSE:The titled composition providing a molding having flame retardancy and yet transparency, prepared by mixing a PE resin with a specified flame retardant which does not adversely affect the transparency of the resin further adding coarse Sb2O3 particles to the mixture. CONSTITUTION:The titled composition prepared by mixing a PE resin or a PE- based copolymer resin with a halogen-containing flame retardant (e.g., chlorinated paraffin) and/or a phosphorus-containing flame retardant [e.g., tris(bromo. cresyl) phosphate] which do not adversely affect the transparency of the resin and further adding coarse Sb2O3particles of an average particle diameter >=0.1mm. to the mixture. Although a PE resin itself has good transparency, it has a defect that its transparency is adversely affected by a flame retardant. By the use of a combination of said flame retardants which do not adversely affect transparency and the coarse Sb2O3 particles as a retardant aid, it is possible to impart flame retardancy to the resin without adversely affecting its transparency.

Abstract: PURPOSE:To improve a convenience by identifying dial information by a dial identifying means, transmitting the dial information to a radio equipment by a control means when a redial indication is issued from a data transmission terminal, and attaining a connection with a line. CONSTITUTION:A CPU 5 judges whether or not a serial signal is transmitted from a telephone set 2 side, and when the received signal is a telephone dial calling signal, the CPU 5 judges whether or not the dial number of the signal is a redial condition number. When the number fulfills the condition, the received number is stored in a memory provided at the inside of the CPU 5. When a user dials the redial condition number, a telephone is temporarily hung up while the other party is busy. When the setting of a redial release is not operated by an FAX 4, a redial indication is automatically issued from the FAX 4. Thus, the CPU 5 transmits a telephone dial signal to a radio equipment 1. Thus, when the other party is busy, an interface equipment 3 automatically calls the other party without making a telephone call again by the user.

IPC: H01L21/027
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the generation of speckles and the like when a pattern is transferred by a method wherein the very small vibrations, which do not lower resolving power, are given while a mask is being exposed. CONSTITUTION:The light sent from an optical system of illumination is projected on the reticle 19 on which the circuit pattern to be transferred has been drawn in advance, and the circuit pattern is reduction-transferred on a wafer 21 by a projection lens 20. The reticle is placed on a reticle stage 30, and it is pressed from four directions by piezoelectric elements 31, 32, 33 and 34. When voltage is applied to the piezoelectric elements 31, 32, 33 and 34, they expand or contract in accordance with the voltage, and as a result, a reticle stage 30 is moved. By properly increasing or decreasing the applied voltage, microscopic vibrations can be given to the reticle 19 itself in the direction at right angle to the optical axis. When the amount of vibrations is maintained at the diffraction limit or thereabout of the lens, a pattern having no coherent pattern deterioration can be obtained without decreasing resolving power.

A handrail having 10-700 μm differences in level formed in the longitudinal direction of a pipe surface at internals of a distance of 1-50 mm is molded. This constitution reduces the generation of cold and static electricity without mounting a cover, and simply manufactures a handrail having anti-bacterial operation.
