Patent JP-S6331122-A (JP)
Title: Manufacture of semiconductor device
Inventor: IKEGAMI MASAAKI
IPC: H01L21/3213
Filed: 1986-07-24
Abstract: PURPOSE:To relieve any damage resultant from etching process of contact parts with respective step differences by a method wherein the etching rate of the second insulating films formed on the corresponding parts to contact holes is specified to be higher than that of the first insulating film of the other parts. CONSTITUTION: Photoresist layers 13 are removed while BPSG films 14 are deposited on overall surfaces to be heated for flattening surface performing wet etching process. At this time, the etching rate of SCG films 12 left as corresponding parts to contact holes being much higher than that of BPSG films 14, any damage to the surface of a gate electrode 4 can be sufficiently relieved even if there are step differences between the gate electrode 4 and impurity diffused regions 5a, 5b further subjected to different positions in the depth direction of contact parts. Furthermore, with SCG films 12 themselves in the state to be controlled not to expand in the peripheral directions, contact holes 8, 9a and 9b reaching the gate electrode 4 and the impurity diffused regions 5a, 5b can be made easily.

Title: Control grid control circuit of vacuum tube
Inventor: YAMASHITA YASUO
IPC: H01J27/02
Filed: 1982-10-08
Abstract: PURPOSE:To draw out a large controllable plate current from a vacuum tube by driving a potential of a control grid from a negative to a positive potential level. CONSTITUTION:When an ON signal is given to a base of a trnsistor (TR) 10, the TR10 is turned on, a voltage of a negative driving power supply 1 is divided by resistors 13 and 14, and a voltage across the resistor 14 is given as a control grid voltage Vcg. This voltage has a negative polarity. As a signal given to the base of the TR10 is smaller, said Vcg approaches 0. When this voltage reaches zero, a current flows to a base of a TR11 with a positive driving power supply 2, the TR11 turns on, the voltage of the power supply 2 is impressed to the resistor 14 and the Vcg becomes positive. Since the potential level of the control grid is changed smoothly from the negative to the positive value by using this circuit, the controllable plate current is drawn out much by about 20%.

Title: Method and apparatus for recovering ink ejection state
Inventor: IKUI KAZUNORI
IPC: B41J2/18
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To recover ink ejection state of all nozzles surely even with an weak suction force by a structure wherein a cap surrounding the nozzle outlet chokes the outlet of a part of nozzles out of a plurality of nozzles and surrounds the outlet of remaining nozzles. SOLUTION: A print head 30 has a plurality of nozzles 34 for ejecting ink. Since a bubble 40 is generated or a foreign matter 42 is mixed in the nozzle 34 or an ink supply chamber 36, a unit 50 for recovering the initial ink ejection state is provided. The recovery unit 50 has a rubber cap 52 for choking the outlet of a part of nozzles out of a plurality of nozzles 34 in the print head 30 and surrounding the outlet of remaining nozzles thus intercepting the outer air. When a suction pump is operated under that state, a bubble 40 is sucked along with ink only from a remaining nozzle facing a recess 54. Consequently, ink ejection state of the remaining nozzle is recovered surely even if the suction force is weak.
