IPC: C23F1/00
Filed: 1990-10-03
Abstract: PURPOSE:To accurately and easily measure the stock removal of chemical polishing by immersing work to be polished in a chemical polishing soln., capturing generated gas, measuring buoyancy due to the gas and calculating the stock removal of polishing. CONSTITUTION:Work W to be polished is immersed in a chemical polishing soln. 1 in a treating vessel 2 with a transferring device 7 in accordance with a signal from a microcomputer 6 and oxygen generated by polishing the work W is captured with the capturing vessel 30 of a capturing device 3. Buoyancy applied to the device 3 by the storage of the captured oxygen is measured with a digital scale 4 and a signal corresponding to the buoyancy is inputted into the microcomputer 6.

Title: Position control method for motor
Inventor: TAKAMUKAI HIDEYUKI
IPC: H02P25/098
Filed: 1989-10-12
Abstract: PURPOSE:To reduce the quantity of revolution up to stoppage and vibro-motive force given to a work by turning a motor by using a command pattern as a speed change, in which no displacement is generated between the motor and the work, in the greater part of the quantity of the motor rotated and revolving the motor at low speed within a range including a trigger signal. CONSTITUTION:A position command controller 3 checks the count (PZ) of a counter 8 and the integrated value PM of command pulses stored in a RAM 5, and recognizes these difference PM-PZ as a positional deviation Pe. The positional deviation Pe represents the difference of a command position generated by the follow-up delay of a motor and an actual location. When the position command controller 3 receives a trigger signal, it draws a deceleration pattern during a speed command pattern by using the pulse number only of a Ps-Pe section, and outputs a positional command value on the basis of the deceleration pattern. Accordingly, the motor is stopped by the fixed quantity of stoppage and revolution.

Title: Production of liquid crystal display element
Inventor: OTA KAZUHIDE
IPC: G02F1/1335
Filed: 1986-11-07
Abstract: PURPOSE:To prevent visuality from being deteriorated by working burrs so that their height from a film face is uniformed and sticking the reflecting face side peripheral edge part of a reflecting member fast to the peripheral edge part of a cell on the optical film sticking side while holding a gap between the reflecting face and a film face. CONSTITUTION:An optical film 2 is stuck to one outer surface of a liquid crystal cell 1 and the peripheral edge part of the film 2 is cut off from the normal direction of a film surface by a mechanical means to form burrs 3 projecting from the film surface on the cut part. Then, the burrs 3 are worked so that the height from the film surface is uniformed and the reflecting face side peripheral edge part of the reflecting member is stuck fast to the optical film sticking peripheral edge parts on both the sides of the cell 1 while holding the gap between the reflecting face and the film face by the burrs 3. Consequently, the generation of a troublesome phenomenon such as interference stripes and double display can be prevented and the invasion of uncured sealing agent into the gap between the optical film and the reflecting plate immediately after its application can be suppressed.

Title: Dry etching method
Inventor: TERAOKA ARITONO
IPC: H01L21/302
Filed: 1993-10-25
Abstract: PURPOSE:To allow anisotropic etching of silicon with low damage and high selectivity by setting the temperature of a substrate to be etched within a specific numerical range and setting the translation energy of a molecular beam at a threshold level for starting the etching being determined by the temperature of the material to be etched or above. CONSTITUTION:A substrate 101 to be etched is cleaned chemically, treated with diluted hydrofluoric acid and washed with water before it is thrown into a substrate replacing chamber 102 evacuated through an exhaust system 110. The substrate 101 is then transferred, by means of a load lock 111, to a substrate holding mechanism 103 equipped with a resistor heater where the substrate 101 is thermally cleaned at about 780 deg.C under ultrahigh vacuum before it is held at a predetermined temperature of 100-630 deg.C. Anisotropic dry etching having high selectivity causing low damage is realized by utilizing a neutral halogen molecular beam having translation energy slightly higher than a threshold level determined by the temperature of the board 101 to be etched.

Title: Image converter
Inventor: ADACHI HIDEYUKI
IPC: H04N1/21
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce output amount of paper, eliminate the need for revision of a program of an opposite party terminal equipment and to reduce the transmission information quantity even when a document format is changed. SOLUTION: Format conversion information includes an image type and a compression system corresponding to an opposite party terminal equipment. An image conversion section 12 converts document data into image data with an image type designated by the format conversion information, and an image data companding section 13 compresses image data according to the compression system designated by the format conversion information. The compressed data is used for the terminal equipment of the opposite party. Since the compressed data are recorded on a recording medium as magnetic information or optical information, output amount of paper is reduced. Since the converter 1 designates the image type and the compression system or the like, revision of a program of the terminal equipment of the opposite party is not required even when the format of a document is changed.  The transmission information quantity is reduced by compressing the image data.

Title: Semiconductor device and its manufacture
Inventor: AOYAMA MASASHIGE
IPC: H01L21/28
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device which can be driven at a high speed, while the occurrence of a short channel effect is suppressed even if the device is made finer. SOLUTION: Since a semiconductor device has a structure such that a source region 12 and a drain region 13 are bent toward a gate electrode 9, with the regions 12 and 13 being partially protruded, the regions of the source and drain regions 12 and 13 facing the gate electrode 9 become smaller, and the parasitic capacitances between the gate electrode 9 and the source and the drain regions 12 and 13 can be reduced. In addition, since the impurity concentrations in the protruded sections are lower, no wide space-charge region is formed around the protruded sections. Therefore, the occurrence of a short-channel effect can be prevented.
