Title: Remote education system with learning function
Inventor: KOTATSU NOBUO
IPC: G06F17/00
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To improve education efficiency by applying only the contents required for a student in remote education at a suitable timing. SOLUTION: Concerning a hybrid type remote education system in which both a server 10 and a client 11 have education contents, advancement of education is estimated by confirming the level of comprehension from a network side corresponding to the condition of study for each student, and when the level is higher than a certain result, these education contents 31 are erased from each client so that the system resource of the client can be effectively utilized. Further, the education contents of just an obstacle for a fully comprehending student are excluded so that the next course can be automatically distributed from the network 20 or a cryptographic key to be taken out of the distributed medium can be distributed. Thus, a student can be concentrated only on the education contents to be originally learnt by himself and learning effect will be enhanced.

Title: Plasma cvd apparatus
Inventor: INOUE SHUICHI
IPC: H01L21/205
Filed: 1988-03-04
Abstract: PURPOSE:To grow a plasma CVD film where few dust particles adhere to its surface without lowering the operating efficiency and whose film thickness and film quality are uniform by a method wherein a susceptor is brought into contact with the whole of the rear of a wafer and the susceptor can be turned in the perpendicular direction up to a face-up position when the wafer is to be mounted. CONSTITUTION:When a CVD film is to be deposited, a wafer 11 is held face down by using a claw 12. Since the whole of the rear of the wafer comes into contact with a susceptor 13, a potential of the wafer is fixed to nearly a potential of the susceptor irrespective of whether a foreign substance or the like exists or not. In addition, since the potential of the susceptor is kept equal to a potential of an upper-part electrode 15 thanks to a conductive susceptor shaft 14, a potential in a plasma generation region 16 is distributed uniformly inside the face of the upper-part electrode; accordingly, a stable and uniform plasma can be generated. In addition, since the wafer can be turned by means of the susceptor shaft from the face-down position to a face-up position, the susceptor is set in a face-up state when the water is to be mounted and detached. By this setup, the operating efficiency to mount and detach the wafer is not lowered even with a structure that the whole of the rear of the wafer is brought into contact with the wafer.

Title: Microwave oven
Inventor: INOUE MASANOBU
IPC: F24C7/02
Filed: 1989-03-03
Abstract: PURPOSE:To open a door safely by installing a latch switch to work in conjunction with the opening and closing of the door, a viscous mechanism part for the opening and closing of the door, and a lock mechanism part fully opening the door automatically. CONSTITUTION:When a pressure rod 13 is pushed lightly in the vertical direction P to open a door 5, a key 12 under the rod 13 is rotated to release a lock. When a lock mechanism part is released, the door 5 is started to move by a spring 10 and when it is fully opened to the last movable point, there is a possibility that a container is tilted or food-stuffs are split by the reaction of door movement force and therefore a viscous mechanism part using a gear- shaped oil damper and operated at the time of the opening and closing of the door is installed. At that time, if the door 5 is opened even slightly, the key 12 is off from a latch switch 14 to stop the oscillation of microwave. When the operation of closing the door by hand, the reaction force generated by the spring 10 is received, but this force is reserved by a lock mechanism as the energy to open the door next time. Thereby, the leakage of microwave can be prevented and also the door 5 is fully opened safely only when a user pushes the rod 13 lightly.

Title: Reduced projection exposure method
Inventor: NOZUE HIROSHI
IPC: G03F1/76
Filed: 1989-03-03
Abstract: PURPOSE:To improve the reliability and manufacturing yield of semiconductor devices by measuring the reflectivity for ultraviolet rays at the surface of the semiconductor device beforehand, and setting the amount of exposure in response to said reflectivity. CONSTITUTION:Before the exposure of a wafer, the reflectivity of the wafer is measured. When the reflectivity is R3, the optimum amount of exposure E3 at the reflectivity R3 is obtained. All the wafers in the objective lot are exposed with the amout of exposure E3. At this time, the most effective method is as follows: the relational straight line l1 between the reflectivity and the amount of exposure is inputted into a computer in a stepper beforehand; the optimum amount of exposure is automatically computed based on the result of the reflectivity measurement; and the exposure with the obtained optimum amount of exposure is performed automatically. Therefore, the time for exposure, development, size measurement and the like by using a test wafer can be omitted. Even if there is dispersion in reflectivity in the wafer, the pattern size can be formed constantly. In this way, the integrated circuit device whose reliability and manufacturing yield are improved can be obtained.

IPC: B01J47/06
Filed: 1990-03-02
Abstract: PURPOSE:To enhance the regeneration efficiency of an ion-exchange resin by using the regeneration liq. containing the salt having a concn. not lower than the critical aggregation concn. in combination with the magnetic treatment thereof at the time of regeneration thereof. CONSTITUTION:To regenerate the ion-exchange resin which has been used to decolor sucrose liq., a solution of the salt having a concn. not lower than the critical aggregation concn. and contg. K ions, Na ions, etc., is used as the regeneration liq. The use of this liq. lowers the aggregation velocity constant of suspended particles, i.e., the dispersibility of the particles becomes better and this effect lasts for many hours. The ion-exchange resin and the regeneration liq. are also treated with magnetism. In this way the particles which have been liberated in the regeneration process can be prevented from reattaching to the ion-exchange resin. Thus, the regeneration efficiency of the resin is enhanced and the lifetime thereof is also extended.

Filed: 1990-03-02
Abstract: PURPOSE:To improve drilling efficiency and to improve durability of a tool by starting a work to drill a material through rotation of a tool without applying ultrasonic vibration and applying ultrasonic vibration on the tool after a hole is formed in the material down to a given depth. CONSTITUTION:A tool 13 wherein grinding grains are stuck to a tip part in an axial direction is rotated around an axis, and the tip part of the tool 13 is brought into contact with a material to start a drilling work. After a hole is drilled in the material down to a given depth by a drilling work effected through rotation of the tool 13, ultrasonic vibration is applied on the tool 13 by means of an oscillator 15 to perform a work to drill the material. Thus, no ultrasonic vibration is applied on the tool 13 before a hole with a given depth is formed in the material and a drilling work is effected only through rotation in an axial direction. Thereby, the tip part of the tool 13 executes a drilling work in a state that drilling is concentrated to one point on the material.
