Title: Magnetic bubble memory device
Inventor: MINEMURA TOSHIMITSU
IPC: G11C11/14
Filed: 1987-10-20
Abstract: PURPOSE:To prevent an absolute page address after restoration from dislocating by writing header data on the same page address based on the reading timing of normal header data read from the boot loop of other bubble memory chip in the case of rewriting the header data of the boot loop of the bubble memory chip. CONSTITUTION:Bubble memory chips 4-1-4-i are driven by a bubble memory chip driving means 7 in the direction of an arrow A in the same driving timing. Header data H1-Hi for controlling a page stored on respective boot loops B1-Bi are stored so that all the header data H1-Hi can have the same page position P. Thereafter, when a boot loop writing control means 8 rewrites new header data H1' to a boot loop B1 with a magnetic bubble writing means 6-1, the means 8 reads normal header data H2 from one of the boot loops of other memory chips 4-2-4-i, for example, B2, with a magnetic bubble reading means 5-2 and writes normal header data H2 into the same position as the page position P based on the reading timing.

IPC: H01L21/304
Filed: 1990-10-01
Abstract: PURPOSE:To improve device yield by providing a cleaning bath made of synthetic quartz to prevent the contamination of wafers. CONSTITUTION:A cleaning bath 1 for holding a solution 3 of ammonia and aqueous hydrogen peroxide is made up of a pure synthesized quartz. Therefore, the solution 3 can dissolve quartz, but only SiO2 and other silicon compounds may exist in the solution because the quartz contains very little impurity such as heavy metal.

Title: Electromagnetic pump
Inventor: YAMAZAKI YASUHISA
IPC: F04B53/00
Filed: 1994-10-27
Abstract: PURPOSE: To reduce the generation of air cut noise and strike noise by a method wherein a valve part comprises a suction valve and a discharge valve and by cutting the outer peripheral parts of the suction valve and the discharge valve, a moving piece is formed. CONSTITUTION: Through movement of a vibrator 13 laterally vibrated by means of an alternating magnetic field generated according to an alternating current fed to a coil 12a, fluid is discharged from a delivery port 19 through a suction chamber 16, an exhaust chamber 4, an an exhaust hole 17 by means of an intake port 6. Since, during operation, cuts 28a are formed in the peripheral parts of a suction valve 15 and a discharge valve 18 to form a number of moving piece 28, a valve 25 is deformed by a low force. Thus, when the valve part 25 is opened, the valve is momentarily deformed and promptly the suction hole 16 is opened and a flow passage is widely spread and when the valve part is closed, since a reaction force by the moving piece 28 is low, the force of a contact with a partition wall 14 is low.  This constitution causes the valve part of a valve body to be apt to deform, whereby when a valve part is operated to open, a need for a compression force is eliminated, a sufficient flow passage is momentarily formed. When the valve is operated to close, a working reaction force is reduced.
