Patent JP-S63104333-A (JP)
Title: Dry etching method
Inventor: KANAMORI JUN
IPC: H01L21/3065
Filed: 1986-10-22
Abstract: PURPOSE:To easily control incident electrons under the control of a potential to be applied to an electrode for placing a sample to be etched thereby to stably etch the sample by raising the potential of the electrode higher than a plasma potential to etch the sample. CONSTITUTION:When a high frequency voltage is applied from an external electrode 2 to a reduced pressure vessel 1, a plasma is generated in the whole vessel 1. Simultaneously, a positive voltage higher than the plasma potential is applied from a power source 8 to an electrode 6. The electrode 6 is cooled to prevent it from raising the temperature of a sample 7. Since the electrode 6 is higher than the plasma potential in this state, particles charged negatively in the plasma are incident on the surface of the sample 7. Most of the incident negative particles are electrons. Neutral particles attracted to the sample 7 are dissociated by the energy to cause an etching reaction to occur thereat.

Inventor: KANANO YUJI
IPC: B65D41/04
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To enable a sealed state at a neck part with a container lid to be positively kept even if a high movable load is applied to a top surface by a method wherein an annular seal piece closely contacted with the neck part and flexed in a radial outward direction and an annular abutting piece abutted against an interface plane of the neck part are integrally formed at an outer circumferential edge of the inner surface of the top surface wall. SOLUTION: When a female thread 24 of a container lid is threadably engaged with a male thread 58 of a neck part 56 of a container, an annular positioning piece 38 at the container lid descends along an inner circumferential surface of the neck part 56 and at the same time, an annular seal piece 34 of the container lid is closely contacted with an outer circumferential surface 64 at the upper end of the neck part 56 and flexed to cause the neck part 56 to be sealingly closed. Then, the annular abutting piece 36 of the container lid is abutted against an annular interface 66 at the upper end of the neck part 56 and compressed.  At this time, the annular abutting piece 36 is not abutted against the annular top surface 62 at the upper end of the neck part 56, but abutted against the annular interface 66, so that the top surface wall 4 of the container lid is deformed into a dome-shape so as to be expanded upwardly with gas pressure and even if a high movable load acts on its outer surface, the sealed state of the neck part 56 can be positively kept.

IPC: G03C1/025
Filed: 1990-09-18
Abstract: PURPOSE:To effectively obtain the aq. dispersion of photographic additives by adding a pressure which can be regulated and varied to the aq. dispersion to disperse the additives. CONSTITUTION:The pressure which can be regulated and varied is added to the aq. dispersion to disperse the additives. Namely, the disturbance of the dispersion by the bubbles generated at the time of dispersion is suppressed by the operation to remove the bubbles in the dispersion by the pressure reduction, the operation to compress the bubbles by pressurization and to enhance the dispersion efficiency by shearing and the combination of these two operations at the time of mechanically dispersing the photographic additives which are substantially insoluble in water. The problems by the bubbles are solved in this way and the aq. dispersion of the photographic additives which are substantially insoluble in water is obtd. The photosensitive material which is free from dispersion troubles is thus obtd.

Title: Rotation detecting circuit
Inventor: SHIKITA YUKIHISA
IPC: G01D5/244
Filed: 1989-09-26
Abstract: PURPOSE:To make it possible to expand the range of an operating voltage to the voltage of a low power source without decreasing the sensitivity of a magnetoelectric converter element itself too much by determining the resistance value of one ferromagnetic body of the magnetoelectric converter element at a value about twice the resistance value of the other ferromagnetic body. CONSTITUTION:The length of the current path of a ferromagnetic body B in a magnetoelectric converter element 1 is made to be approximately 1/2 of the length of a ferromagnetic body A. A voltage dividing resistor 17 comprising the series connection of fixed resistors R3 and R4 divides the voltage of a positive power source 16 into about 1/3. The voltage is applied to the non-inverted input of a comparator 15. For example, a voltage is applied to the inverted input of the comparator 15 from an output terminal 3 of the element 1. The amount of change due to the rotating magnetic field of a magnet 13 is removed from the applied voltage. The value corresponding to the reference voltage obtained in this way is decreased to about 1/1.5 the value in conventional technology. When the power source voltage is about 3 V, the input voltage in the same phase to the comparator 15 becomes about 1 V. The amplitude of the amount of change obtained at the terminal 3 at this time is decreased to about 92% from the value when the phase input voltage is about 1.5 V. The decreasing amount is less than the amount in the conventional technology. Namely, it is found that the decrease in sensitivity of the element 1 is prevented and the same-phase input voltage can be decreased.

Filed: 1983-12-29
Abstract: PURPOSE:To reliably prevent the occurrence of a lock-up shock, by a method wherein the decrease rate of a slip amount is changed according to the slip amount and the number of output revolutions of a torque converter. CONSTITUTION:A lock-up deciding means 5, which decides whether a power source 1 is in a condition in which lock-up through operation of a clutch is effected, and a slip amount detecting means 6, which detects the relative number of revolutions between input and output elements, are provided. Operation of the clutch is controlled by feedback so that the slip amount of a torque converter is gradually decreased to zero in a ratio responding to the relative number of revolutions between the input and output elements and the number of revolutions of the output element preveiling during instructon of lock-up. This enables the given decrease rate of the slip amount to be changed in response to a slip amount and the number of revolutions of the torque converter, prevents the occurrence of an answering lag of lock-up, and permits reliable prevention of the occurrence of lock-up shock.
