Patent JP-S6363078-A (JP)
Title: Electrophotographic device
Inventor: YAMAMOTO TOSHIRO
IPC: G03G15/20
Filed: 1986-09-04
Abstract: PURPOSE:To form a copy which is scarcely contaminated, by providing an electrostatic charging means between a transfer means and a fixing means. CONSTITUTION:For instance, in case a photosensitive body having a selenium photosensitive layer has been used, a toner image which has been formed on transfer paper 14 through exposure, development and transfer processes has a charge of the negative polarity in case of a positive development, and has a charge of positive polarity in case of negative development. When the transfer paper 14 for holding the toner image is allowed to pass through between each roller 10, 11 of a fixing means, the lower side of the transfer paper 14 is charged to the positive polarity due to a charge of negative polarity of a pressure roller 11. On the other hand, after the transfer process, when the toner image of positive polarity is transferred to the negative polarity by giving a charge of negative polarity to the toner image by an electrostatic charging means 13, prior to the fixing process, the toner image of negative polarity on the recording paper 14 cannot be shifted to the heating roller 10 by a suction force to the transfer paper 14 of positive polarity. In this way, a copy which is scarcely contaminated can be formed.

Title: Lock hopper type powder material supplier
Inventor: TACHIBANA TOSHIO
IPC: F23K3/00
Filed: 1986-09-03
Abstract: PURPOSE:To stabilize the continuous constant amount supply by disposing an air blowing device to the interior of an upper high-pressure vessel and a lower high- pressure vessel, disposing an agitating device in the interior of the lower high-pressure vessel, and bypassing the air in the top air space in the lower high-pressure vessel to a powder carrying pipe. CONSTITUTION:After opening a relief valve 28 to make the interior of an upper high- pressure vessel 11 at the atmospheric pressure, an air cylinder 17 is actuated to open a conical valve 14 to allow the supply of powder from a hopper 15, and, then, after closing the conical valve 14, air is supplied from blowing device 23. When the pressure in the vessel 11 became equal to that of the lower high-pressure vessel 12, an air cylinder 16 is actuated to open a conical valve 13 to cause the powder to drop into the vessel 12. The powder fed into the vessel 12 is agitated to break lumps by an agitating device 22 and an air blowing device 24, and is transported to a carrying pipe 20 through a mixer by a feeder 18. At this time, the air injected into the vessel 12 is bypassed to the carrying pipe 20 by way of a connecting pipe 26, and flows through gaps between screw vanes in the feeder 18. By this constitution, the powder does not solidify in the high-pressure vessels, and a stable and continuous supply of constant amount can be assured.

IPC: H01L21/66
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To perform the stable measurement of film thickness to a substrate in etching treatment. SOLUTION: In a substrate processor which performs etching treatment by soaking a substrate 9 in etchant in condition that the substrate 9 is supported in erect posture in a guide groove 321 made in a support member 32, the measurement end 421 of an optical fiber 42 is positioned at the inner face of the guide groove 321a for supporting the substrate 9a whose film thickness is to be measured. A measurement beam 42La is emitted from the optical fiber 42, and the reflected light 42Lb from the substrate 9 is led to a film thickness meter through an optical fiber 42. As a result, the positional relation between the substrate 9 and the measurement end 421 does not change in every treatment, and further even if the substrate 9 vibrates, the fluctuation of the distance between the substrate 9 and the measurement end 421 can be minimized.  As a result, the stable measurement of the film thickness of the substrate 9 is materialized.

Title: Automatic setting method for binary coding level
Inventor: ISHIGURO KAZUYA
IPC: G06T1/00
Filed: 1985-09-21
Abstract: PURPOSE:To cope with the variation of brightness with high flexibility by setting plural windows to calculate the mean luminance in each window and then calculating the optimum binary coding level according to said mean luminance. CONSTITUTION:In case the positions of parts are roughly decided, the windows 11 and 12 are set inside and outside the parts 21. Here the mean levels of luminance a window 12 inside parts and a window 11 outside parts are set at D1 and D2 respectively. Then these levels D1 and D2 are first calculated for both windows (inside and outside parts) and then the binary coding level S=D1+(D2-D1)XK is calculated (K: prescribed constant). In other words, the background is distinguished from the parts on the basis of the mean luminance of the window inside the parts and by means of the mean luminance difference between the background and the parts. Thus a binary coding level is calculated in response to the brightness despite the variation of the ambient brightness despite the variation of the ambient brightness since the mean luminance of the window inside the parts is used as a standard.

IPC: G01N21/88
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To detect a crack of a substrate of a disc-like data-recording medium at high speed by shedding light on the crack of the substrate and detecting a reflecting light. SOLUTION: A data-recording medium 4 is loaded in such a manner that a center hole 11 is fitted with a projecting part 1a of a spindle 1. An inner peripheral transparent part of the medium 4 is vacuum-chucked. A spindle motor 5 rotates a spindle 1 and the medium 4. A semiconductor laser 2a is driven by a laser-driving source 21 to emit a laser light L to a crack of a substrate at the innermost peripheral part of the medium 4 with an angle of approximately 90 deg.. If a crack 12 is present, the laser light L enters a horizontal plane of the medium 4 with an angle of approximately 40 deg., is reflected at the crack, and returns to a photodetector 2b. The light is detected there and a detection signal is brought into a crack judgment part 7 through an amplifier 3, whereby the presence of the crack is determined.  If the crack 12 does not exist, the laser light L is not returned to the photodetector 2b. It is thus detected that the crack 12 is not present.
