Title: Cathode structure of magnetron
Inventor: HARADA AKAKAZ
IPC: H01J23/04
Filed: 1984-11-07
Granted: 1989-07-01
Abstract: In the magnetron cathode structure to improve vibration resistance without sacrifice of insulation performance, an insulation spacer (19) has a projected portion (19d) at the outside of the section corresponding with a through-hole (13a) of lower end shield (13).  An engaging section (13c) made of a hole to be engaged with the projected portion (19d) is made in the lower shield.  Since the projected portion will engage with the engaging section (13c) of the lower end shield for the vibration in all directions, strength of filament will increase.  Since the insulation spacer is not inserted into the through-hole, the amount of metal to be adhered to the spacer will decrease considerably resulting in improvement of reliability.

Title: Method and circuit for automatically adjusting the variable-gain amplification in a control loop
Inventor: WILFRIED ROHDE
IPC: G05B13/02
Filed: 1987-10-22
Granted: 1996-06-05
Abstract: In a control loop for automatically adjusting variable-gain amplification, a sinusoidal signal with a frequency fo that is critical for the control loop is superimposed over a positioning parameter W. Two synchronous rectifiers S1 and S2 filter out the oscillation components of a control parameter x and of a control difference xd that contain frequency fo, and the components are compared in a comparator VL. A control and regulating circuit C continues to vary the variable-gain amplification at controls RG until the amplitudes of the oscillation components being compared in the comparator are equal. The variable-gain amplification is correct at that point. The variable-gain amplification can even be adjusted in a compact-disk player while the player is in operation.

Abstract: The pin-stacked cell is mfd.  by  (a)  forming  a  transistor region and a field oxide  film  (2)  on  the  substrate  (1),  (b) forming an oxide film (3) of the gate side wall  and  a  SiN  film (4), (c) depositing a dielectric oxide film (5), a polysilicon (6) and a dielectric  oxide  film  (5a)  for  the  formation  of  the capacitor, (d) forming a source-drain contact window and a  trench by the photo-etching process, (e) depositing a  polysilicon  (6a), and implanting an ion, and (f) forming a capacitor dielectric film (5b) and a cell plate (6b). The pin-stacked cell is  used  in  the mfr. of ULSI DRAM devices.
