Title: Dust fall volume measuring apparatus
Inventor: SAITO YOSHIAKI
IPC: G01N5/02
Filed: 1992-07-01
Abstract: PURPOSE:To enable simple measurement in a short time by detecting and displaying a change in oscillation frequency due to a fact that dust particles deposit on a surface of a crystal oscillator by means of a frequency measuring and displaying means. CONSTITUTION:Prior to measurement, a crystal oscillator 1 is left in the atmosphere with an upper electrode 3 directing upward, and then an oscillation circuit 9 and a frequency measuring and displaying apparatus 10 are actuated. Dust particles A such as dust contained in the atmosphere fall to gradually deposit on the electrode 3. AC voltage from the circuit 9 is given from terminals 6, 6A via support pieces 5, 5A and electrodes 3, 4 to both sides of a crystal piece 2, and the crystal piece 2 oscillates with its proper oscillation frequency by the ac voltage. When the dust particles A deposit on the electrode 3, a drop in the oscillation frequency of the crystal piece 2 is detected by the weight of the dust particles A and displayed by a display 11 so that the deposit amount of the dust particles A can be measured.

Title: Resin molding of coil
Inventor: ISOTANI ZENJI
IPC: H01F41/12
Filed: 1985-08-10
Abstract: PURPOSE:To securely and rationally perform resin molding of a coil by continuously injecting resin for dipping and cast molding. CONSTITUTION:When the resin for dipping poured in a metal mold 5 is gradually dipping into a coil 1, the injection speed for permeating into the inside of the coil 1 is made faster than that of the liquid surface rising in the space a. With the resin injected in this way, the air remaining in the inside be is not prevented from going out of the coil 1, thereby allowing the coil 1 to be completely dipped in the resin. The injection of the resin is terminated when the resin oozing out from the top surface of the coil 1 joins the resin rising within the space a. Following that, the resin for injection is poured into a resin container 10. When the resin for cast molding is injected onto the bottom of the metal mold 5, replacement is done by raising the resin for dipping, thereby discharging the resin for dipping remaining in the circumference of the coil from the discharge opening 12 into a container 11. The injection of the resin for cast molding is terminated when the resin for cast molding is completely replaced.
