Title: Apparatus and method for cleaning semiconductor wafer
Inventor: TSUCHIYA MASATO
IPC: H01L21/304
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a cleaning effect with a simple process, without using surfactants or various chemicals by having a container formed of a light- transmitting material irradiated with light and cleaning the surface of a semiconductor wafer immersed into a liquid within a vessel. SOLUTION: Holes (+) and electrons (-) are generated within a semiconductor wafer W, by having the semiconductor wafer W immersed into pure water P filled in a quartz glass container 10 irradiated with light from a light source L. At the contact surface between the semiconductor wafer W and the pure water P, oxidation and reduction reactions takes place to generate O2 , O2 , .OH, H<2> O2 , O, etc., and these can decompose the bonds C-H and C-O of organic substances adhered to the surface of the wafer W and remove them from the wafer surface to clean the surface of the wafer W. Furthermore, the pure water P can also be made to appropriately contain necessary chemicals such as hydrogen peroxide, etc.

Title: Bending process data preparing method
Inventor: TAKADA MASAAKI
IPC: B21D5/02
Filed: 1992-05-28
Abstract: PURPOSE:To set a bending sequence adapted to reality by detecting whether a deformation of a work caused by an interference is a permanent deformation or a recoverable deformation, and executing continuously setting of the bending sequence, when it is the recoverable deformation. CONSTITUTION:When product information, a die, a mechanical shape and a bending sequence are set automatically or manually, an interference check is performed, and whether an interference exists or not is decided. In the case the interference does not exist, bending process data is prepared, and in the case the interference exists, a coordinate calculation of an interference point is executed, and a stress calculation of a dangerous cross section E is executed. A calculated value and an elastic limit stress value are compared, and whether a deformation of a work is a permanent deformation or not is decided. In the case of the permanent deformation, whether a bending sequence can be change or not is decided, and when the change is impossible, whether the die and the machine can be changed or not is decided. In the case it is impossible, die notch data is prepared as additional data of the die. When additional working data is prepared, based on this die notch data, the inference can be eliminated.

Title: Transporting device
Inventor: TSUNODA MASAMI
IPC: H04B10/00
Filed: 1990-05-29
Abstract: PURPOSE:To enable an operator to attain the follow-up of a transporting device just with movement of the operator by performing the control based on the detection data on the light received from a modulated light output means of the operator in order to drive a shift/direction conversion means. CONSTITUTION:An operator carries an infrared ray transmitter 15 with him/her and outputs continuously the infrared rays. The distance varies between the transmitter 15 and an infrared intensity detector 14 with movement of the operator. Therefore the intensity of the infrared ray inputted to the detector 14 is changed. When the operator moved in the direction further from a vehicle body, the intensity of the infrared ray is reduced. The output of the detector 14 is also changed in response to the intensity of the infrared ray. Thus the analog signals are turned into the digital ones by an A/D converter 19 and inputted to a CPU 11. The CPU 11 compares the detection data with the prescribed threshold value. If the former is less than the latter, a drive motor 3 is controlled via a motor driver 17 and the vehicle body is moved close to the operator.

IPC: G11B5/02
Filed: 1984-07-04
Abstract: PURPOSE:To execute sufficiently recording to a medium up to a high recording density by constituting the titled device so that a signal of a high recording density is recorded by a lower recording current than that of a signal of a low recording density, in case of a vertical magnetic recording. CONSTITUTION:In order to extend a recording density characteristic to a high density side, it is necessary to make a recording current comparatively small, and in order to improve an OVER WRITE characteristic, it is necessary to make the recording current large at least at the time of recording of a low recording density. When recording is executed by a recording current 30mA and a recording current 20mA, when the recording density is <=50KFCI, and when said density is >=50KFCI, respectively, a device can be operated by a recording density 80KFCI. In this way, recording can be executed sufficiently up to a high recording density area, therefore, a storage device being small in size and having a high density can be realized.

Title: Ink ribbon cassette
Inventor: KAGAMI YOSHIJI
IPC: B41J33/52
Filed: 1986-06-14
Abstract: PURPOSE:To perform the stable feeding of an ink ribbon, by a method wherein the shaft of the gear of an ink ribbon cassette is arranged in almost parallel to the feed path of the ink ribbon in a movable manner and stopping the rotation of said gear when the shaft of the gear moves in the direction opposite to a prescribed direction. CONSTITUTION:When an ink ribbon is fed normally, the rotary directions of follower side and driving side feed gears 24, 22 are respectively shown by arrows A1, A2 and the advance direction of the ink ribbon comes to a C-direction. However, when either one of the driving side feed gear 22 and the follower side feed gear 24 is ready to generate reversal, the friction force shown by an arrow F is generated on the engaging surface of the feed gears and the gear 24 begins to move in a B-direction by the friction force F. When the gear 24 has further moved to an E-position, the sharp part of a stopper 18 is hooked with the elastomer layer of the gear 24 to stop the reversal of the gear and the reverse advance of the ink ribbon in a D-direction is prevent to make it possible to stably feed the ribbon. At this time, since the gear 24 is pushed back immediately by the recovery force of a spring 20, rotation is reopened soon and printing is continued.

Filed: 1989-06-01
Abstract: PURPOSE:To sticking two plastic substrates together with satisfactory productivity by using a hot melt adhesive agent without lowering adhesiveness and limiting a process by heating an adhesive agent layer before the two plastic substrates are stuck together and sticking them together under vacuum. CONSTITUTION:By a substrate supporting means to coaxially support the two plastic substrate at a prescribed interval, two plastic substrates 71 and 71' are supported with the adhesive agent layer inside.

Filed: 1990-05-28
Abstract: PURPOSE:To energize and heat a work for an extremely short time to perform welding thereon by high-frequency high electric power obtained by discharging electric power accumulated on step-up storage parts of electricity in order in a short time. CONSTITUTION:A switch control part 14 controls a GTO of each semiconductor switch circuit 13 and discharges the step-up storage parts 11 of electricity in order. Charging operation is carried out immediately continuously on the discharged step-up storage parts 11 of electricity and discharging is carried out repeatedly. Consequently, high-frequency output is generated on a secondary side of a matching transformer 15. A high-frequency high current is carried to the work by supplying this to electrodes 10a and 10b. This current is carried concentrating on the end face of the work by a skin effect of high frequency and a proximity effect of high-frequency currents carried in the opposite directions mutually and heating and welding are performed. At this time, since the heating time is extremely short, thermal diffusion to the inside of heat generated on the surface is little and only the surface can be subjected to impact heating effectively.
