    摘要： A mold clamping device in an injection molding machine comprising: a first die plate for supporting a first metallic die; a second die plate for supporting a second metallic die; a die plate feeding unit for relative displacement of the first and second die plates on the table; electromagnetic coils disposed respectively on opposing surfaces of the first and second die plates; and a control device for controlling the amount of electric current fed to the electromagnetic coil. Magnetic attractive force generated by the electromagnetic coil is used for clamping the metallic dies.

    摘要： A phase difference detection device able to detect a phase with a high precision is provided. A phase difference detection device 4 detecting a phase difference ¸ between an excitation signal Ss and a second detection signal Sd in accordance with a rotation position ¸ of a rotary body 101 has a reference counter 13 performing a count in synchronization with a first clock pulse CLK1 and reset when the excitation signal Ss causes zero cross down, a velocity detection unit 19 acquiring information capable of specifying the rotation velocity of the rotary body 101, a pulse conversion unit 21 outputting a second clock pulse CLK2 by using, as a pulse interval Tp, a time specified based on the information acquired by the velocity detection unit 19 and required for the rotation of the rotary body 101 by an angle corresponding to 1 count of the reference counter 13, and a phase counter 23 in which a count value counted by the reference counter 13 is set at an initial value for each fall of a second detection signal Sd, and which performs count in synchronization with the second clock pulse CLK2.

    摘要： The present invention is directed to provide a method for manufacturing a die for press forming of glass in which cracks are not easily caused in a surface covering layer. A surface covering layer made of an amorphous Ni-P alloy is formed on the surface of a base material made of a steel having a martensitic structure or made of steel in which µ-carbide is dispersed in low carbon martensite matrix. Then, the base material and the surface covering layer are heated to change the base material into a troostitic structure or a sorbitic structure and change the surface covering layer into a eutectic structure of Ni and Ni 3 P. Preferably, the base material contains 0.3 wt% or more and 2.7 wt% or less of carbon and 13 wt% or less of chromium, and the heat treatment is carried out at 270°C or more.
