Title: Method for applying insulating varnish to ultra fine enameled wire, and device therefor
Inventor: KOBAYASHI AKIMASA
IPC: B05D1/28
Filed: 1995-04-26
Abstract: PURPOSE: To prevent the occurrence of a disconnection or appearance failure by vibration by providing a varnish absorbing cloth-like piece between a varnish squeezing felt for nipping an ultra fine enameled wire and a coater roll to supply insulating varnish. CONSTITUTION: Insulating varnish 1 is pulled up by the rotation of a coater roll 2, and continuously adsorbed by a varnish absorbing cloth-like piece 6 having one end part in contact with the surface of the roll 2. The soft cloth-like piece 6 is normally bonded to the roll 2 surface to supply the varnish 1 to a varnish squeezing felt 4 to which the other end is connected by capillary effect. At that time, the vibration of an ultra fine enameled wire 3, which had been generated with the roll 2, is not generated at all since the wire 3 is not in contact with the roll 2, and the vibration of the cloth-like piece 6 in contact with the roll 2 is absorbed and extinguished because of its softness. The influence of the vibration caused by the rotation of the roll 2 is thus entirely eliminated.

Title: Scintillation camera
Inventor: KUMAZAWA YOSHIHIKO
IPC: G01T1/164
Filed: 1982-07-20
Abstract: PURPOSE:To improve spatial resolution, sensitivity nonuniformity characteristics, etc., by using a nonlinear photoelectron multiplier tube. CONSTITUTION:A grid G is provided between the anode A and final-stage diode D among multistage diodes D of the photoelectron multiplier tube 3 which converts scintillation light into an electric signal. A signal component voltage VD from this diode D is impressed to a grid voltage control circuit 33 through a window level setting comparator 32 with a threshold voltage VNL to control a grid voltage VG through the circuit 33. Then while VD<VNL, the voltage VG is between the voltage VD and the voltage of the anode A to secure a constant electron multiplication rate and when VD>=VNL, it becomes closer to the potential VDD of the final-stage diode D to determine the circuit 33 so as to decrease the multiplication rate by screen effect. Consequently, the amplification of a large output is suppressed by nonlinearity and a decrease in sensitivity nonuniformity caused by spatial distortion is prevented. Similarly, the spatial resolution characteristics are also improved.

Filed: 1988-05-24
Abstract: PURPOSE:To improve welding quality and efficiency by reading out in order welding conditions every time a timed value of a timing means attains the time of data and performing welding based on the welding conditions to facilitate setting the welding conditions of divided welding sections. CONSTITUTION:The optimum welding conditions of the plural sections formed by dividing a weld line at prescribed positions are set by a welding condition setting means. The data of the divided positions are then set by a divided position setting means. The welding line passing time when a welding torch 5 moves up to the terminus from the starting point on the weld line is then timed by the timing means and an arithmetic processing unit calculates the timewise data corresponding to the divided positions based on the weld line passing time and the data of the divided positions. At the time of welding, the arithmetic processing unit renews in order the welding conditions from a storage means and reads out and outputs these every time the timed value of the timing means attains the time shown on these timewise data. A welding performing means performs welding under the welding conditions set optimally for every section of the weld line.

Title: Detecting method for short-circuiting spot at conductor-covered insulating pipe
Inventor: KIKUCHI HIDEO
IPC: G01M3/16
Filed: 1981-08-11
Abstract: PURPOSE:To detect a spot where an outer covering material and a core tube short-circuit, by a  method wherein a conductive core tube, an outer periphery of which a conductive sheathing  material covers through the medium of an electrically insulating heat insulator 3, is earthed,  and a periodical voltage is applied all the way through to the outer sheathing material and the  core tube to detect a leak magnetic field or a change in the leak magnetic field. CONSTITUTION:A conductor-sheathed insulating pipe 1 is constituted such that a conductive  outer sheathing material 4 is formed on an outer periphery of a conductive core tube 2 through  the medium of an electrically insulating heat insulator 3. When detecting a spot 5 where the  core tube 2 and the outer sheathing material 4 short-circuit, the core tube 2 is earthed, and an outer of an oscillator 7, employing, for example, a fork oscillator, is applied all the way  through to the core tube 2 and the outer sheathing material 4 through a diode (D) 14, in parallel with which a switch (S) 13 is placed. If, with a S 13 closed, a voltage is applied, and an  electrostatic induction detector 8 is caused to approach the insulating pipe 1, a leak electric  field is detected irrespective of the presence of a short-circuiting spot, and a speaker 10 sounds. If, which a S 13 closed, a rectified voltage is applied through a D14, and in the case of no  short-circuit spot, no current flows after charging by the use of an electrostatic capacity, and  it is not detected by a detector. But if there is a short-circuiting spot, it can be detected.
