Title: Plasma processing device
Inventor: TAKAGI KENICHI
IPC: H01L21/3065
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To achieve the plasma processing of excellent uniformity even when a substrate is large-sized by providing a magnetic field generating mechanism capable of independently changing a gap between respective permanent magnets which are coaxially disposed and electrodes and an electrode surface temperature adjustment mechanism. SOLUTION: An annular fixing plate 20 in which a plurality of annular permanent magnets 16 are fixed in the surface of an electrode 12 is coaxially disposed. When the electrode-side magnetic poles of the magnets 16 adjoin each other on the inside and on the outside, they are constituted so as to have an opposite polarity. The fixing plate 20 is mounted by forming a gap so that the heat of the electrode 12 is not directly transmitted to the magnets 16. Also, the fixing plate 20 is made into the structure in which the distance between the fixing plate 20 and the electrode 12 can be optionally provided by moving it in the axial direction. The distribution of plasma density generated in a discharging receptacle is uniformalized by setting the distance so that it becomes gradually larger towards a center in the central part of the electrode.  Further, a cooling tube 21 is fixed in the upper surface of the fixing plate 20, thereby preventing the deterioration of the magnets 16 due to the rising of a temperature.

Title: Inspection table for translucent of transparent film
Inventor: HONGO TSUTOMU
IPC: G01N21/958
Filed: 1992-12-15
Abstract: PURPOSE:To furnish an inspection table which uses a shutter blind for a camera so as to prevent reflection in relation to a translucent or transparent film. CONSTITUTION:A shutter blind for a camera formed by coating habutae woven fabric with black rubber is laid, as a nonreflective blind 5, all over the surface of an inspection table 2. Since the reflectance of the nonreflective blind 5 is uniform and very small, the blind does not reflect an irradiation light the S/N ratio of a foreign substance detection signal is not deteriorated. Since the toughness thereof is very large, besides, the blind is hardly flawed with abrasion, and even when it is flawed slightly, the reflectance does not change. Accordingly, foreign substance inspection can be conducted with high reliability for a large number of translucent or transparent films.

Title: Joint for piping
Inventor: FUJISHIN SHIGENOBU
IPC: F16L41/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption and purify exhaust gas by disposing a magnet by turning a south pole in the direction of a center axis of an inner pipe within a hollow part formed between the inner pipe and an outer pipe and providing at least one opening part which is communicated with the hollow part. SOLUTION: Because all the magnets 20 are arranged in opposed states by turning a south pole in the direction of a center axis of an inner pipe 14, magnetic fields repelling each other are formed within the inner pipe 14 and fluid passing through the inner pipe 14 can be atomized by the exciting action. Thus, because the magnets 20 are arranged on the outer peripheral surface of the inner pipe 14 and a hollow part 19 is made a vacuum state, fluid passing through the inner pipe 14 is atomized and the function becomes stable without being affected by an ambient temperature. Therefore, when fluid passing through the inner pipe 14 is fuel of an internal combustion engine, coupling property with oxygen is improved by atomization and combustion efficiency is improved.  Therefore, an output of the internal combustion engine is increased and an effect of improving fuel consumption can be obtained.

Title: Chemical liquid heating device
Inventor: KADOTANI KANICHI
IPC: H05B3/40
Filed: 1992-12-17
Abstract: PURPOSE:To heat chemical liquid having light emission property safely and effectively by installing a light source lamp for heating and a quartz glass tube through which the chemical liquid flows having a distance between each other in a closed space container formed to have inner surfaces of double- parabola reflection mirror surfaces. CONSTITUTION:A closed space container 16 is formed as double-parabola mirrors comprising an upper half of a parabolic surface mirror, and a lower half formed as a CPC as a subject parabolic surface having a perpendicular long axis. Radiation light of a halogen lamp 20 installed on a focal point of the parabolic surface mirror of the upper half is reflected on the mirror surface, and parallel beams get into the CPC. They are then reflected by the mirror surface of the CPC to be converted to a chemical liquid flow tube 18 installed on the focal point and comprising a quartz glass tube, so chemical liquid is heated. Because the lamp 20 is installed above the tube 18, the chemical liquid can be prevented from getting in contact with the lamp 20 if the tube 18 is broken, or the chemical liquid is not contaminated if the lamp 20 is broken. The chemical liquid having light emission property can thus be heated safely and effectively.

IPC: H04L12/58
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a communication system which can simplify the operability of a user and which can improve immediateness and to provide a communication terminal and an electronic mail device. SOLUTION: A fixed terminal 1 monitors whether an electronic mail addressed to it itself exists in a server 7 or not at every prescribed time. When the electronic mail exists, the electronic mail is received and a terminal presence/absence recognition request is transmitted to a charger 3. When the charger 3 receives the terminal presence/absence recognition request, it recognizes whether a portable terminal 2 is loaded on the charger 3 or not and transmits information to the fixed terminal 1 as terminal presence/absence information. When the portable information terminal 2 is loaded on the charger 3 in accordance with terminal presence/absence information, the fixed terminal 1 judges that the user is near the fixed terminal 1 and it does not execute anything.  When the portable terminal 2 is loaded on the charger 3, the fixed terminal 1 judges that the user does not exist near the fixed terminal 1, calls the terminal number of the portable information terminal 2 through MODEM 4 and directly transfers the electronic mail which is automatically received in the portable information terminal 2.
