IPC: C23C16/24
Filed: 1988-02-29
Abstract: PURPOSE:To form a uniform thin photosensitive body film on the surface of a substrate by using a circular waveguide for a microwave as the vacuum chamber, and arranging the substrate along its axis when raw gas is introduced into the vacuum chamber wherein the substrate is arranged, and the raw gas is excited by microwave energy to form a thin film on the substrate. CONSTITUTION:The substrate 2 and the circular waveguide 1 are coaxially set in the vacuum chamber 1 used as the circular waveguide. The gaseous raw material of an Si compd. is introduced between the substrate 2 and the vacuum chamber 1, and a microwave is introduced from a microwave oscillator 8. The raw gas is excited by the microwave energy to produce the plasma, and a thin amorphous Si film is formed on the surface of the substrate 2 to produce a photosensitive body for electrophotography. Since the vacuum chamber is used as the waveguide for a microwave, the transmission loss of the microwave is reduced, and a uniform thin film is formed over the whole periphery of the substrate 2 at a high rate since the whole outer periphery of the drum-shaped substrate 2 is used as the waveguide.

Abstract: PURPOSE:To perform the appreciation for a bonding system in a very short time, by supplying power intermittently to a semiconductor device so that the turn-on duration has no bad influence upon a mount system. CONSTITUTION:The relation between a transient thermal resistance Rth and the turn-on time of a transistor is shown in the figure and is divided to a region 7 from a semiconductor pellet to the part near a case and a region 8 from the part near the case and the ambient atmosphere. That is, a temperature variance DELTAT in the turn-on tine is given by expression DELTAT=PonxRth(on) where the  transient thermal resistance and the power consumption at a turn-on time t(on) are denoted as Rth(on) an Pon, respectively. Consequently, when a switch 5 is opened and closed repeatedly, the temperature of the pellet is fluctuated repeatedly in the range of DELTAT, and a repetitive stress is generated on the interface between a bonding wire and the pellet by the difference in coefficient of thermal expansion. Experimentally, if the turn-on time is within one second, the test is performed without causing the degradation of a mount system.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To increase the speed at which a long cylinder is measured. SOLUTION: A subject 1 for measurement is rotated in A direction on a surface plate 2 and moved in B direction during measurement. A unit 3 includes a measuring jig 4 and a micrometer 5, the measuring jig 4 having a flat plate part 6 serving as a contact plate and a shank 7. The flat plate part 6 is placed horizontally above and at a distance to the surface plate 2. The shank 7 is used to connect the flat plate part 6 to the micrometer 5, with the flat plate part 6 forced toward the horizontal plane of the surface plate 2. The subject 1 for measurement is rotated in A direction and moved in B direction and under the flat plate part 6. In the case of a curved subject 1 for measurement, the flat plate part 6 is pushed up. Then the micrometer 5 detects the amount of movement of the flat plate 6 as the amount of curve of the subject 1 for measurement.  Thus by causing one or more rotations of the subject 1 for measurement below the flat plate part 6, the curve of the subject 1 for measurement can be measured, with the measuring speed increased because conventional troublesome operations are not needed. Automation is also made possible.

Title: Method for increasing gas absorption rate
Inventor: TANAKA TOSHIO
IPC: B01D53/14
Filed: 1986-03-07
Abstract: PURPOSE:To acceleratedly increase the rate of absorption of a component to be absorbed into an absorbent component by impressing a high voltage on the gas-liq. interface between the component to be absorbed and the absorbent component, and generating electric discharge. CONSTITUTION:An AC or DC voltage is impressed on a needle electrode 12 at the upper part of an evaporation vessel 10 contg. the component A (e.g., water) to be absorbed and an electrode 14, hence electric discharge is generated at the gas-liq. interface, and the evaporation of the component A is accelerated. Meanwhile, a high voltage is impressed between electrodes 22 and 26 provided in an adjacent absorption vessel communicating with the vessel 10 through a passage part 18 and contg. the absorbent component B (e.g., lithium bromide soln.) to generate electric discharge at the absorption interface, and the absorption rate is increased. Moreover, electric discharge is generated at the passage part, and the component A is ionized. When a DC voltage is impressed, for example, positive discharge is generated in the evaporation vessel, negative discharge is generated in the passage part, and positive discharge is generated in the absorption vessel by changing the polarity. As a result, the component A is more effectively evaporated, moved, and absorbed.
