Title: Method and device for quantitatively discharging granule
Inventor: SHIMOMURA HAJIME
IPC: B01J4/02
Filed: 1991-11-11
Abstract: PURPOSE:To quantitatively discharge the sample of granule by injecting compressed air to granular substance on a table which is cut out and transferred by rotation of the table, allowing the granular substance to fall from the table and discharging the same. CONSTITUTION:Granule is quantitatively discharged by using a bottom face rotary type table feeder wherein granular substance in a storage tank or a hopper 1 is cut out on the table by rotating the bottom face table. In this case, compressed air is injected to granular substance on the table 2 which is cut out and transferred by rotation of the table 2. The granular substance is allowed to fall and discharged. Especially compressed air is injected at a prescribed angle to the surface of the table 2 and simultaneously at a prescribed angle to the tangential direction of the table 2. The air flow is injected in the direction opposed to the direction of rotation of the table 2 and injected in such the direction that the air flow does not directly touches a cut-out port 5 and the granular substance just after being cut out on the table 2 while keeping injected air quantity. As a result, trouble for stopping rotation of the table is prevented.

Title: Manufacture of non-linear voltage resistor
Inventor: OGITA KIYOBUMI
IPC: H01C7/10
Filed: 1990-10-31
Abstract: PURPOSE:To contrive improvement in the electric characteristics such as thermal loss, deterioration due to lightning impulse, anti-lightning strength and the like by a method wherein the title resistor is mainly composed of zinc oxide, and amorphous silicon oxide in globular fine grains having uniform particle-size is added thereto. CONSTITUTION:SiO2 a subsidiary ingredient, is formed into amorphous particles having spherical shapes and a uniform particle size when the main component of ZnO and other additive components are mixed and they are wet-mixed with an organic binder. As a result, the particle-size segregation and the specific gravity segregation in a slurry are suppressed, and compositional distribution is stabilized. Also in sinterability, the reaction of amorphous SiO2 with the main component of ZnO is made to proceed smoothly and uniform; unreacted SiO2 is not generated by the contraction in sintering, and the generation of voids is reduced. As a result, a non-linearly voltage-dependent resistor having improved electric characteristics such as thermal loss, lightning impulse deterioration, strength against lightning impulse and the like, can be obtained.

After its entire surface is heated over critical point, a magnet 14 applies fixed magnetic fields to it. By virtue of Meissner effects, the magnetic field is grasped on the entire surface of the recording medium. Then, light is projected according to the type of an original, and the magnetic field on which light is projected is extinguished, thereby recording a negative latent image. As a result, a magnetic head for recording a magnetic latent image is not needed; therefore it can be recorded quickly.
