Title: Pipe inner surface grinding device
Inventor: SAKOTA AKINORI
IPC: B24B49/16
Filed: 1989-09-08
Abstract: PURPOSE:To keep the grinding force of a grinding wheel constant without being influenced by the finned state of the inner peripheral surface of a pipe and the shape of the grinding wheel by controlling the control voltage value of a pressure control valve in such a way that the driving cuurent of a driving motor becomes the fixed value. CONSTITUTION:The grinding force of a grinding wheel 6 to the inner peripheral surface of an object pipe 14 is detected as the driving current of a driving motor 5. The pressing force of the grinding wheel 6 to the inner peripheral surface of the object pipe 14 is controlled by the control power of a pressure control valve 13. Accordingly, when the driving current of the driving motor 5 is larger than the specified value, the control voltage of the pressure control valve 13 is lowered by a control circuit 10, and when the driving current of the driving motor 5 is smaller than the specified value, the control voltage of the pressure control valve 13 is raised by the control circuit 10. As a result, the driving current of the driving motor 5 can be constantly kept to the fixed valve, and therefore the grinding force of the grinding wheel 6 to the inner peripheral surface of the object pipe 14 can be kep constant without being influence by the finned state of the inner peripheral surface and the shape of the grinding wheel.

Filed: 1991-09-13
Abstract: PURPOSE:To suppress the increase of a noise generated from a focus actuator by providing a low-pass filter between an adding means and a subtracting means, and preventing the deterioration of the level of a total sum signal. CONSTITUTION:In a total sum signal preparing part 3, entire photodetection signals from light receiving parts 1a-1d are added by an arithmetic amplifier 13, and the currents are converted into voltages, so that the total sum signal can be prepared. At that time, the deterioration of the level of the total sum signal is generated each time a condenser spot passes through the pre-format area of a magneto optical disk. Then, the deterioration of the level of the total sum signal is suppressed by allowing the total sum signal to pass through a low-pass filter 5, and it can be turned to almost a plane waveform. Thus, the increase of the noise generated at the total sum signal can be suppressed at the time of dividing a driving signal by the total sum signal.

Title: Release sheet
Inventor: FUKAO RYUZO
IPC: G03G7/00
Filed: 1994-09-05
Abstract: PURPOSE: To obtain a transparent sheet for an OHP or the like which can be used at least twice for the top and back surfaces, can be easily disposed and has excellent property for problems of resources and environments by adding such a property that the film can be peeled in a sheet state to a transparent film on a substrate. CONSTITUTION: A transparent film as a toner receiving layer 3 has a peeling property from a substrate film 1 so that after an image is formed and the image becomes unnecessary, the film can be peeled from the substrate to erase the image. In this method, to prevent peeling of the film during the sheet is normally handled, it is preferable to select a film having strong film forming property and adhesion property. By forming transparent films on both surfaces of the substrate, after an image formed on the one surface is erased by peeling, another image can be formed on the other surface. Thus, one sheet can be used twice. The film peeled is enough thin compared to the substrate film 1 and has low rigidity, so that it can be torn by hands or crushed into a small size and can be easily scrapped.
