Title: Formation of insulating film
Inventor: HASHIMOTO MASAYUKI
IPC: C23C16/44
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To enable the formation of a very thin insulating film for use in semiconductor circuit devices. SOLUTION: A multi-chamber system consists of a transfer chamber 1 and process chambers 4, 5 connected with the transfer chamber 1. When an insulating film is formed on a wafer 10 by a CVD process using this multi-chamber system, a pretreatment process, such as removal of spontaneous oxide films, is performed in one 4 of the process chambers before the CVD process. Then the CVD process is performed in the other process chamber 5, and the wafer is transferred from one process chamber to the other through the transfer chamber 1. In this method, a pretreatment process and a CVD process are integrated into one in the multi-chamber system. As a result, wafers are not exposed to the atmosphere after the pretreatment process, and thus problems, such as re-formation of spontaneous oxide films and sticking of particles, do not arise.

Inventor: NIWASE YOSHIO
IPC: D06F33/02
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To leave cost as it is and control the rotation of a motor irrelevant to the power supply frequency by controlling ON-OFF time of the motor by a damped waveform width of back electromotive force of the voltage between capacitor terminals which is detected in OFF time of the motor in dehydrating process. SOLUTION: When a dehydrating process is executed without changing a pulley for transmitting the rotation to a washing and spin basket, the rotation speed in acceleration characteristics of 60Hz becomes higher compared with that of 50Hz in continuous dehydration process. Therefore, the ON-OFF of the motor is executed by a method applying a conventional method for detecting cloth quantity without changing the pulley for transmitting it to a washing and spin basket according to the frequency.  In this case, the ON time of the motor is set long T1 and the OFF time of the motor is set short T2 till the set rotation speed so that the acceleration characteristics of continuous dehydration process is made equal to that of the normal continuous hydration, and after reaching the set rotation speed, the ON-OFF time of the motor is changed into T4 -T3 , and these T1 , T2 , T3 , T4 are so controlled as to be repeated.

Title: Manufacture of laminated capacitor
Inventor: SAKABE YUKIO
IPC: H01G4/12
Filed: 1989-12-19
Abstract: PURPOSE:To eliminate the possibility of silver biting and improve accuracy in dimensions by attaching a metal cap to both edges of a sintered element body with a depletion layer within the inside and then dipping it into a fluxing metal for pressing the melted metal into the depletion layer through gap between the sintered element body and the metal cap. CONSTITUTION:An element body 1 where a metal cap 7 is fitted to both edges is dipped into a fluxing metal, press fitting of the fluxing metal is initially vacuum-absorbed, and then pressure is applied to the fluxing metal for performing press fitting. Thus, the fluxing metal is press-fitted into the cap 7 for a fine gap between the element body 1 and the cap 7 winding and then is allowed to flow into the gap 2 for forming an internal electrode 3. When it is taken out of the fluxing metal, flaw of metal within the gap 2 is prevented due to the cap 7. Thus, there is no possibility of silver biting and a laminated capacitor with improved dimensional accuracy can be obtained.

Abstract: PURPOSE:To observe an image of the phase difference of a bulk-like sample in a desired range by using a LEEM. CONSTITUTION:Electron beam emitted from an electron gun 41 is deflected to the X, Y directions by deflecting coils 44, 45. This beam is converged on the surface of a sample 50 by a lens 48 and a cathode objective lens 49. Consequently, the surface of the sample 50 in a predetermined range is scanned by the converged electron beam. At this stage, a diffraction image is formed at a predetermined position of the front surface of the sample 50, but the lens 48 forms this diffraction image at a position of a division type electron beam detector 47. The output signal of the division type electron beam detector 47 is input to a signal processing circuit 53, and a predetermined computing is performed, and the signal is input to a CRT 54. The output signal of the signal processing circuit 53 is thereby displayed by the CRT 54 synchronously with the scanning by the electron beam emitted from the electron gun 41.

Filed: 1989-12-20
Abstract: PURPOSE:To eliminate the clogging of a filter by rotating or half rotating a water holding piece 3 by means of a rotating device and providing a pressurized contact part atop the water holding piece. CONSTITUTION:A soln. is put into an injecting body 1 and is sucked from the filter holes of a jig body 4, by which the soln. is filtered through the filter 6 and the specimen in the soln. is captured on the filter 6. The rotating device 7 is assembled to the rear surface of the water holding piece 3 and the water holding piece 3 is rotated when the filter 6 is clogged by this filtering. Since the rear surface of the filter 6 and the front surface of the water holding piece 3 are in contact with each other, the rear surface of the filter 6 is rubbed by the rotation of the water holding piece 3 and the materials, such as protein, clogged in the fine holes of the filter 6 are removed. The materials, such as protein, clogged in the fine holes of the filter 6 are more effectively removed by the pressure, such as water pressure, generated by the corotation of the pressurized contact part 8 with the water holding piece 3 and the sliding contact force generated by the direct contact of the pressurized contact part 8 if the pressurized contact part 8 is formed atop the water holding piece 3.
