Title: Method for correcting blade edge diameter of boring tool
Inventor: KAWAGUCHI YOSHIKAZU
IPC: B23B29/034
Filed: 1990-11-30
Abstract: PURPOSE:To achieve accurate and rapid correction of a blade edge diameter by setting the blade edge position correction of a blade tool to a correction data setting device or a stage- changing data setting device based on an input value from a correction command means, and by setting a correction factor per unit displacement based on the difference between the measured inclination of the inclined surface and the theoretical one to a corrected correction factor setting device. CONSTITUTION:When a stepping motor 20 is rotated in the forward direction, a correction master screw 18 is rotated to move a movable table 25 in the rearward direction. A blade edge diameter correction rod 12 moves rearward in the spindle 3 through a bearing 17, and an inclined cam 13 moves. This arrangement allows a blade 9 to be protruded while a stepped part 14 of the blade tool 9 is brought into contact with the inclined surface of the inclined cam 13 in a sliding manner, and the blade diameter is corrected to increase. If the stepping motor 20 is rotated in the reverse direction, the correction master screw 18 is rotated in the reverse direction and the blade edge diameter correction rod 12 moves forward, and the blade tool 9 is withdrawn inside, leading to correction to decrease the blade edge diameter. In addition, if the rotation of the stepping motor 20 increases, the required surface of the inclined cam 13 is positioned so as to be tightly pressed against the stepped part 14 of the blade tool 9, and the blade edge diameter of the blade tool 9 is stage-changed. This constitution eliminates the diversified dimension of the processed workpieces and improves the processing precision.

Title: Adaptive automatic equalizer
Inventor: TAKAHASHI TSUYOSHI
IPC: H03H17/02
Filed: 1992-12-17
Abstract: PURPOSE:To obtain an adaptive automatic equalizer which is prevented from deteriorating in bit error rate by correcting a frequency offset. CONSTITUTION:An input signal is stored in a buffer memory 11, signals of plural frequencies in a specific range are modulated in order by a modulator 12 with a training signal read out of the memory 11 as a carrier, and the modulation output is sent out through a filter part 14. A subtraction output obtained by subtracting the output training signal of a training signal generation part 17 from the output is added for each carrier frequency, the minimum value in the addition output is retrieved, and an initial value estimation part 25 estimates an initial value on the basis of the carrier frequency corresponding to said minimum value. Then a frequency offset estimation part 26 obtains a unit vector of a phase angle based upon equivalent error data by using the estimated initial value as an initial value and the output of the filter part 14 is corrected with the unit vector.

IPC: H01M2/10
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a fitted portion from coming off even if a battery case elastically deforms by arranging recess and projection fitting portion for joining at a corner portion producing less elastic deformation. CONSTITUTION:The upper battery case 5 having recessed shape of fitting portion 4 is housed in the lower battery case 3 having projecting shape of fitting portion 2, the lower battery case 3 is covered by the upper battery case 5. A battery 1 is put into the lower battery case 3.

Title: Heating apparatus for substrate
Inventor: TAKASUKA EIRYO
IPC: H01L21/205
Filed: 1989-12-26
Abstract: PURPOSE:To make an energy efficiency good and to make the temperature of a substrate uniform by a method wherein a plurality of infrared lamps are arranged in a concentric circle shape by using the shaft of a disk-shaped specimen stage as the center. CONSTITUTION:While a specimen stage 13 is being turned by using a shaft 12 as the center, infrared rays are radiated from infrared lamps 17. Thereby, a substrate 14 is heated; its temperature is measured at individual zones by using a thermocouple 22 and radiation thermometers 23. Since a plurality of infrared lamps 17 are arranged in a shape matched to the movement of the substrate 14, i.e. in a circular shape using the shaft 12 as an axis, relative positions of the infrared lamps 17 to the substrate 14 are not changed, and a stable heating operation can be executed. In addition, since the radiation intensity, i.e., the heat-generating amount of the infrared lamps 17 is fed back and controlled at individual rows, the temperature of the substrate 14 placed on the specimen stage 13 is always uniform even when a rapid heating operation is executed, and it is possible to prevent the substrate from being slipped by an uneven temperature.

IPC: B23P19/02
Filed: 1990-11-30
Abstract: PURPOSE:To smoothly draw out chuck pins by fitting a C ring on the outer periphery of a shaft in the expanded state, thereafter narrowing the chuck pins, and moving the positions of the chuck pins by a fixed distance in such a direction to bring the chuck pins near the shaft at the same time that the C ring is pressed against. the outer periphery of the shaft. CONSTITUTION:When a C ring 1 is fitted on the larger diameter part of a shaft 8, the ring is fitted in the expanded state, so that the center of the C ring 1 comes to 01. When chuck pins 2a, 2b are retracted with the C ring 1 left on the large diameter part of the shaft 8, the center comes to O2, that is, the center of the C ring 1 is moved by a distance t2 between O1 and O2. Further, when the C ring 1 in the expanded state is narrowed, expanding holes are moved by a distance of t1, and thus the ring is moved by a distance of t1+t2. By moving a sliding body 47 merely by a distance of t1+t2 in the cylinder 46a of a 90 deg. turning body 46 turned by a turning cylinder by a chuck pin moving cylinder 9, the chuck pins 2a, 2b can be easily drawn out from the expanding holes 1a, 1a after the C ring is fitted on the larger diameter part of the shaft 8.

Abstract: PURPOSE:To obtain a favorable image by preventing the occurrence of any waving motion in a cut sheet end, and such chips ascribed to a cutting failure occurring. CONSTITUTION:A stationary blade 26 is attached to a range extending over the whole cross direction of a sheet material 7. In addition, a movable blade 21 traveling in the sheet cross direction as pressure-contacting with the stationary blade 26, and cutting the sheet material 7 in conjunction with the stationary blade 26, is set up at the downstream side in the sheet conveying direction rather than the stationary blade 26. Likewise, a guide member 34 guiding the sheet material 7 is set up at the downstream side in the sheet conveying direction rather than the movable blade 21. In succession, a movable blade side tip part 34a of the guide member 34 is installed in space between a sheet cutting part 26a and a sheet cutting side tip 21a of the movable blade 21 and in the vicinity of this sheet cutting part 26a, respectively. With this constitution, any motion of the sheet material 7 to be cut is regulated by the tip part 34a of the guide member 34, and thereby cutting the sheet material 7 by both these stationary and movable blades 26 and 21 is made so better, and thus any waving motion at the end of the sheet material 7 is prevented from occurring.
