IPC: B23G1/16
Filed: 1987-05-07
Abstract: PURPOSE:To prevent breakage of a tap, by a method wherein, when it is detected that a main spindle guide member is moved toward a mounting part, a motor is reversed to move a tape, mounted on a main spindle, in a direction in which it is escaped through a lower hole. CONSTITUTION:A male screw part 18 is formed on the outer peripheral part of a main spindle 16 of a threading unit 31, and a female part 20 is formed in the inner peripheral part of a main spindle guide member 19. When a tap 24 is collided with a position displaced from the lower hole of a workpiece or the tap 24 is collided with the bottom of the low hole of a blind hole to suddenly stop rotation of the tap 24 and exert an unreasonable force on the main spindle 16, even when rotation of a chuck shaft 25 is stopped, the main spindle 16 is rotated in a manner to slide over a joint 22 part. Through detection of elevating movement of the main spindle guide member 19, a motor 12 is immediately reversed to raise the main spindle 16. This constitution reliably prevents breakage of the tap 24 and damage of a workpiece.

After the surface except these parts is oxidized by using said non-oxidizable substance layer left into side-wall form as a mask, this non-oxidizable substance layer 19 is removed to form a minute window. The exposed part of the semiconductor substrate is connected with a base electrode by an impurity-including semiconductor layer and that impurity is diffused into the substrate to form a graft base 7. Furthermore, after a side wall is formed in the impurity-including semiconductor layer, an intrinsic base part is formed by ion implantation.

Title: Digital communicating system
Inventor: IKEGAMI FUMIO
IPC: H04L27/233
Filed: 1986-05-13
Abstract: PURPOSE:To obtain an arbitrary complementary characteristic without being influenced by the amplitude characteristic of a demodulating signal by executing the phase change of a carrier signal corresponding to digital information by dividing it into a first half and a second half of a time slot, and setting independently the phase changing quantity in the time slot and the phase changing quantity between codes. CONSTITUTION:When the arrival time difference between the D wave and the U wave of the same contents to arrive through two routes different in propagation path length is T, the D wave and the U wave correspond to the same phase relation at sections (b) and (d) and the relation of the phase difference at a section (c). When the synthesizing wave of the D wave and the U wave is demodulated, a phase changing quantity theta between codes is related to only the amplitude of an output signal, and a phase changing quantity PSIin a time slot is related to only the complementary relation of the amplitude change of the output signal in the sections (b) and (d) and the section (c). Consequently, since phase changing quantities theta and PSI can be independently set, the amplitude of the output signal is enlarged and the complementary characteristic can be also set to the best place.

Title: Color assigning device for glass painting
Inventor: MORITO YUKO
IPC: B44F11/02
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To replace the color of a colored glass material with a color most approximate to the color of an original image without causing a color variation, when deciding the color of each of pixel of a glass painting based on the original image. SOLUTION: The color of each of pieces of an original image 2 is read by a single color sensor 8 through allowing the permeation of the color through each of optical fibers forming a bundle of fibers 7 or a bundle of optical fibers. Further, the color of each of the pieces which is read is replaced with the color of a colored glass material. In this case, the color of each of the pieces is averaged in the analog mode. This process is different from the process to decided the color by averaging the output signals of numerous pixels digitally per piece, but need not perform an extra operation on chromatic data which is read. Consequently, the level of the color variation is low on account of the unnecessity to perform the extra operation, hence less oppoerunities for the generation of noise in the process.
