Title: Magnetic modulation coil driving circuit
Inventor: WACHI SHIGEAKI
IPC: G11B11/10
Filed: 1991-10-01
Abstract: PURPOSE:To improve the switching characteristic of the driving circuit of a magnetic modulation coil and to obtain effective magnetic force. CONSTITUTION:When a field effect transistor (FET) 8 is turned on and the FET 9 is turned off from a state the FET 8 is turned off and the FET 9 is turned on, current flowing through a coil 14 through a series circuit of a resistor 12 and the coil 10 flows through the drain of the FET 8. Further, the current flowing through the drain of the FET 9 through the series circuit of the resistor 13 and the coil 11 is interrupted in a moment. At this time, though the current, as well flowing through the coil 11 is interrupted, when the current flowing through the coil 11 is changed, counter electromotive force is generated in the coil 11 so as to cancel the change. Thus, since the current flows through the drain of the FET 8 in a moment through the coil 14 by the counter electromotive force, the magnetic force is generated in a moment in the coil 14.

Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/00
Filed: 1994-10-20
Abstract: PURPOSE: To prevent the projection of a ceramic sleeve from the end face of a ferrule body and the increase in connection loss by the optical connecting state of the end face of optical fibers and to lessen the dependency of connection loss on temp. by grinding the ferrule in a cooling state or a state of raising the temp. of the ceramic sleeve to a temp. higher than the temp. of the parts exclusive thereof. CONSTITUTION: The height of the front surface of the ferrule 20 and the front end position of the ceramic sleeve 26 are varied at the time of grinding. To this end, the ferrule 20 is ground in the cooling state or the state of raising the temp. of the ceramic sleeve 26 to a temp. higher than the temp. of the parts exclusive thereof. The coefft. of linear expansion is higher for plastic than for ceramics. Then, the ferrule body 22 made of the plastic shrinks more than the ceramic sleeve 26 and the ceramic sleeve 26 projects when the ferrule is cooled. The ferrule body 22 restores the length and its projection is prevented when the ferrule is ground in this state and is restored to ordinary temp. even if the ceramic sleeve 26 having high hardness projects from the end face.

Thus, the width of write timing e generated based on the output pulse c of the pulse generation circuit 1 and the phase margin is increased. Consequently, the design of data write timing becomes easy and reliability improves.

IPC: G21F9/28
Filed: 1990-10-22
Abstract: PURPOSE:To effectively remove and clean sticking matter which sticks in a body to be cleaned by supplying a proper amount of air bubbles in the body to be cleaned such as complex equipment. CONSTITUTION:Compressed air is supplied from gas piping 14 to jet injection gas 17 from a nozzle 13 to the body 12 to be cleaned as shown by an arrow. Many air bubbles, i.e. bubbling is caused in cleaning liquid 11 by this injection gas 17. As the bubbling is caused, a two-phase flow of air and water is formed nearby the body 12 to be cleaned and a three-dimensional circulation flow is generated. This two-phase flow adds a three-dimensional upward, downward, and lateral liquid force to the matter sticking on the body 12 to be cleaned at all times. Further, the air and water which differ in density strike on the sticking matter repeatedly at all times with the fluid force. The force operating on the sticking matter is increased and the sticking matter 18 separates from the body 12 to be cleaned with the vibrating force.
