Filed: 1994-09-08
Abstract: PURPOSE: To improve dependence on undercoat by forming a O3 -TEOSoxide film on a plasma silicon oxide film subjected to hydrophobic treatment after a reaction is made between the plasma silicon oxide film and a TEOS gas on the surface of a wafer to conduct the hydrophobic treatment. CONSTITUTION: Upon formation of a film of a preset thickness on a wafer W, hydrophobic treatment of a plasma silicon oxide film commences. O2 gas supply and impression of a high-frequency voltage are suspended while a TEOS gas alone is continued to be introduced into a chamber 12 which is maintained in a TEOS gas atmosphere for a preset period of time to make the plasma silicon oxide film in contact with the TEOS gas on the wafer for the hydrophobic treatment. Upon completion of the hydrophobic treatment, the wafer W is taken out of a device 10 and stored in a cassette to be transferred to a film- forming device of the O3 -TEOS-oxide film. And the O3 -TEOS-oxide film is formed. This makes it possible to improve substantially the undercoat dependence of the O3 -TEOS-oxide film to be formed on the oxide film.

Title: Cutoff control relay circuit
Inventor: KANO SHUNSUKE
IPC: H02H3/02
Filed: 1989-09-18
Abstract: PURPOSE:To grasp the actual operating condition easily by measuring the absolute value of the load current of a current transformer, on the basis of the voltage across a fixed resistor connected on the secondary of the current transformer in series with variable resistors for setting the detected secondary current value. CONSTITUTION:When the output of CT is applied to a fixed resistor R1 through a parallel circuit of two variable resistors VR1, VR2, the voltage across the fixed resistor R1 is proportioned to the secondary current of CT regardless of the variable resistors VR1, VR2. The voltage across the resistor R1 is amplified by an operational amplifier OP2, and the absolute value of a load current is obtained by CPU1. Next, voltage VDD is inputted to OP1 through a resistor R4 having a sufficiently large resistance and a change-over switch SW1. Then, OP1 outputs the level L and recognizes that CPU1 is in a state of reading a set value. The voltage across R1 determined by the positions of VR1 and VR2 is amplified by OP2, and A/D converted by CPU1. Then, a cutoff set current is read by the set position of VR2. This enables us to grasp the actual operating condition easily.

Title: Driving device for position switching
Inventor: TAKAGI YUICHI
IPC: G05D3/00
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for maintenance and to securely perform switching between pressure application and separation by engaging a rotary member with a driving shaft and rotating them in one body, arranging a return member which engages the rotary member rotatably, and energizing the return member with an energizing spring. SOLUTION: When a motor 4 rotates clockwise in the separation state of a cam 2, the rotation is transmitted to the cam shaft 1 through an input gear 5 to rotate the cam 2 counterclockwise. When the cam 2 reaches an abutting position, the motor 4 stops and stays in this state. When the motor 4 is rotated counterclockwise, the cam 2 is switched from the pressure application state to the separation state. An engagement part 9 formed on the input gear 5 rotates engaging the return member 6 when the input gear 5 rotates counterclockwise and when the return member 6 rotates, the energizing spring 7 expands to apply a clockwise force to the cam shaft 1. If a momentary break of power supply is caused owing to a power failure while the cam 2 is at the pressure application position, the cam shaft 1 rotates clockwise with the energizing force of the energizing spring 7.  Consequently, the switching can be secured without any maintenance.

Title: Method for measuring smoothness of coating surface
Inventor: INAOKA MASAHIKO
IPC: G01B11/30
Filed: 1986-10-11
Abstract: PURPOSE:To evaluate a two-dimensional coating surface over a wide range with high accuracy, by picking up the image of the vertical stripe lattice projected to the coating surface by a two-dimensional image sensor to process the same. CONSTITUTION:A vertical stripe lattice panel 2 is arranged to the part diagonally upward with respect to a coating surface 1 on one side thereof and the vertical stripe lattice image of said panel 2 is projected to the coating surface 1. A CCD type TV camera 3 for picking up said image is arranged to the part diagonally upward with respect to the coating surface 1 on the other side thereof and connected to an image signal processing part 10. As an orange peel state worsens, the incident image to the camera 3 increases in the disturbance degree of luminosity and, when an image signal wave form is monitored by a CRT monitor tube 14, the wave form of a signal level changes corresponding to the change in luminosity caused by the vertical stripe lattice image. By this method, the image data corresponding to one picture picked up by the camera 3 are taken in RAM 13 of the processing part 10 and processed by analytical CPU 13 and a smoothness level is evaluated corresponding to the number of inflection points being detected.

Title: Optical memory disk, method for copying memory disk and optical recording reading out device
Inventor: TAKEI HIROYUKI
IPC: G11B7/24062
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To shorten data transfer time by inserting a purple color film or org. photochromic material into the optical disk of a resonator structure and reading out the contents of a memory by the wavelength of selectively transmitted light at the time of simultaneous irradiation with two wavelengths. SOLUTION: The change rate of the Fabry-Perot resonator may be changed by a change in the complex index of refraction of the photochromic material 19 if this resonator is constituted by holding the photochromic material 19 between two sheets of translucent mirrors 20. If the photochromic material 19 is irradiated with the light 21 of the wavelength λ1 when this material is in the state A, the greater part of the light is reflected like arrows 22. If, however, the irradiation is sustained, the photochromic material 19 is converted to a state B by a phtoochemical reaction and the complex index of refraction is changed and, therefore, the incident light 21 of the wavelength λ1 passes the resonator. As a result, data '1' is recorded in the photochromic material 19.
