Abstract: A granular stabilizer for chlorine-containing polymers, which is formed by granulating a hardly fusible or infusible powdery stabilizer for chlorine-containing polymers or a mixture of said powdery stabilizer with a powdery stabilizer aid through an organic solid binder or dispersion medium, wherein respective primary particles of said powdery stabilizer or said powdery mixture are surface-treated with the organic solid binder or dispersion medium in an amount of 2 to 15 parts by weight per 100 parts by weight of said powdery stabilizer or said powdery mixture, which is smaller than the critical liquid absorption of said powdery, and said primary particles are granulated into particles having an average particle size of 0.1 to 2 mm by fusion bonding of the surface treatment layers of the organic solid binder or dispersion medium.

Abstract: A buckle including a frame member attached to an end of a band, and a clasping member rotatably attached to an end of another band is disclosed. An engaging projection having a hook portion and beveled portion is provided on the underside of the clasping member and a lock device is provided in the frame member. The lock device includes a slidable first operating member having a beveled edge and a slidable second operating member having a releasing member. The hook portion engages with the beveled edge and the releasing member engages with the beveled portion to push up the clasping member at the disengagement of the hook portion.

Abstract: Disclosed is a granular stabilizer for chlorine-containing polymers, which is formed by granulating a hardly fusible or infusible powdery stabilizer for chlorine-containing polymers or a mixture of said powdery stabilizer with a powdery stabilizer aid through an organic solid binder or dispersion medium, wherein respective primary particles of said powdery stabilizer or said powdery mixture are surface-treated with the organic solid binder or dispersion medium in an amount of 2 to 15 parts by weight per 100 parts by weight of said powdery stabilizer or said powdery mixture, which is smaller than the critical liquid absorption of said powdery, and said primary particles are granulated into particles having an average particle size of 0.1 to 2 mm by fusion bonding of the surface treatment layers of the organic solid binder or dispersion medium.

Abstract: A marking apparatus has an arm with a seat section for enabling the arm to be mounted on a support plate, in the proximity at one of its ends. A main body of an actuating section is fixedly secured to one surface of the arm in the proximity of its other end. The main body of the actuating section has a function of placing a "defective mark" on a defective semiconductor chip, in response to a signal applied thereto.

Abstract: A sound producing device for watches comprising an electromagnetic exciting means having a coil and a permanent magnet, and first and second vibration plates disposed on opposite sides of the electromagnetic exciting means. The natural frequencies of both vibration plates are different from each other. The first vibration plate is vibrated by magnetic force and the vibration of the plate causes the resonant vibration of the second vibration plate.

Abstract: An electronic timepiece including a battery, a drive motor, a drive, a display, and electronic circuits for driving said motor. The motor is a pulse motor and comprises a core, coil, yoke and rotor. The rotor includes a worm gear having worm teeth which engage with a gear wheel. The teeth on the worm gear are arranged and configured such that the initial and final portions of each tooth which engage with the gear wheel are parallel to the plane of rotation of the rotor thereby preventing torque applied to the gear wheel from being transmitted to the rotor.

Abstract: A stabilizer composition for chlorine-containing polymers having a much reduced tendency to blow at the molding step, which comprises (A) an inorganic stabilizer having a power volume of at least 0.5 cc/g, said stabilizer (A) consisting essentially of at least one member selected from the group consisting of silicates of metals of Groups II and IV of the Periodic Table and composites of silicate acid with oxides, hydroxides and carbonates of said metals, and (B) an organic additive having a boiling point or decomposition point higher than a chlorine-containing polymer-processing temperature, said organic additive (B) being incorporated into the stabilizer (A) at a weight ratio (A) : (B) of 1 : at least 0.1 so that the pore volume ratio defined by the following formula: ##EQU1## WHEREIN PVc denotes the pore volume (cc/g) of the entire composition and PVa denotes the pore volume (cc/g) of said inorganic stabilizer (A),is not higher than 0.8.
