Title: Phase locked-loop circuit
Inventor: SUEHIRO YOSHIKAZU
IPC: G11B20/14
Filed: 1989-11-22
Abstract: PURPOSE:To secure operation even if a disk has a defect by inhibiting a playback signal/no signal discriminating circuit from being initialized in the operation of a decoded signal 'L'-level quantity counter. CONSTITUTION:The playback signal/no signal discriminating circuit 3 generates a counter start instruction signal at an output terminal 11 by a phase counter start/stop control circuit 4 when a magneto-optic disk playback signal is at 'L' level continuously for a certain period, and operates the decoded signal 'L'-level quantity counter 5 to counter the number of 'L' levels during the period, thereby operating a phase inversion signal generating circuit 15 when the counted value is larger than a constant value. Further, the counter 5 outputs an initialization inhibition signal to the circuit 3 throughout the operation of the counter 5. This configuration provides resistance to output generation at a gap part due to a slight disk defect and secures the operation even when the slight defect is present.

Title: Buffer device of valve
Inventor: NONAKA YOSHINORI
IPC: F16K1/36
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce speed of a valve body accurately immediately before a valve seat and the valve body come into contact each other when a valve is closed by providing a fitting section which has a minute clearance at two sections on the upstream side and the downstream side in a contact section of the valve body and the valve seat. SOLUTION: In a reheat steam valve of a high and intermediate pressure turbine, a cylindrical fitting section 3 on the upstream side and a fitting section 4 on the downstream side which have a minute clearance are formed at nearby two sections of a contact section between a valve body 1 and a valve seat 2. When the valve body 1 is closed, the flow of steam is blocked first in the fitting section on the downstream side. Since flow rate is reduced at this time, pressure in a clearance C is increased. After that, B section is fitted, and then A section is also fitted, and C section enters a condition in which it is communicated with the outside only through minute clearances in A and B sections. If the valve body 1 is closed further from this condition, steam inside C section is compressed and pressure is increased.  Since this pressure becomes force for pushing the valve body 1 back, speed of the valve body 1 is reduced.
