Title: Centrifugal type impact mill
Inventor: MURATA HIROYUKI
IPC: B02C13/14
Filed: 1989-03-10
Abstract: PURPOSE:To avoid local abrasion by forming a projecting part projected toward a rotor chamber to the end part of the collision face part of a collision plate near to the rotor chamber. CONSTITUTION:When rock 7 is thrown from the discharge port 9 of a rotor chamber 4, it is allowed to collide against both the collision face part 10a ad the projecting part 12a of an anvil 8a. The rock 7 allowed to collide against the end part of the projecting part 12a near to the rotor chamber 4 is curved to the direction M. The collision part of rock 7 is positioned to the left side of an initial anvil 8'a. Even when abrasion of the anvil 8'a is progressed and furthermore the horizontal cross-sectional shape of a collision face part 10'a has reached the 2-dotted chain lines a-d, the distance to the fitting part 14 from the end part of the projecting part 12a near to the rotor chamber 4 is made long. Thereby abrasion is uniformized and the service life of the collision plate itself is prolonged.

Title: Phase comparating circuit
Inventor: YOKOGAWA FUMIHIKO
IPC: H03L7/089
Filed: 1987-03-13
Abstract: PURPOSE:To attain the phase comparison even with an input signal having only one set of edge information by adopting the constitution such that the phase of the input signal and that of the clock are compared by an FF and two latch circuits. CONSTITUTION:An output edge data signal of an AND gate 1 is inputted to an FF 2, which is set at its leading edge. The output of the FF 2 is inputted to a data terminal of an FF 3, which latches the data at the leading edge of the clock. A terminal, Q of the FF 3 is connected to a reset terminal of the FF 2, which outputs the edge data and a pulse having a width corresponding to the time difference information of the clock. The output of the FF 3 is inputted to a buffer 6 and also inputted to an FF 4. Since the inverted clock is inputted to the clock terminal of the FF 4, the FF 4 latches the input at the other edge of the clock. Thus, since an AND gate 5 outputs the pulse corresponding to the width of the clock to a buffer 7, the buffer 7 outputs a signal opposite in polarity to that of the buffer 6 to enable the phase comparison of the signal.
