Title: Hob processing method by electric discharge processing machine
Inventor: SENOO TAKASHI
IPC: B23H9/00
Filed: 1984-06-01
Abstract: PURPOSE:To process a hob raw material at a time over the entire blade width by means of a general purpose machine by subjecting an electrode having a shape matching a series of the blades engaged with each other to electric discharge machining while bringing it to a hob raw material in a radial direction thereto. CONSTITUTION:An electrode 7 having a shape matching a series of baldes engaged with each other along an axial direction thereof and held in their lower ends between adjoining grooves of a hob to be processed is mounted on an electric discharge processing machine head 6, and arranged facing to a hob raw material 1 supported between mounting arbors 2. The entire of the blade is processed at a time over its full width while lowering the head 6 and linearly moving the electrode 7 in a radial direction with respect to a hob raw material 1. Then, with the electrode 7 being elevated, the hob raw material 1 is rotated by one groove for electric discharge machining in the same manner. The machining is repeated over the whole periphery of the hob. With such arrangement, the full blade width can be processed at a time with a general purpose machine for improving efficiency.

Title: Detection of insulation breakdown for insulated rail joint
Inventor: NAGASE KAZUHIKO
IPC: G01R31/02
Filed: 1981-07-17
Abstract: PURPOSE:To predict the occurrent of an insulation breakdown and prevent troubles in a signal device, etc. by providing a simple device on a vehicle and detecting the insulation breakdown in the insulated rail joint that occurs only when vehicle passes. CONSTITUTION:It is assumed that rail current from a rail current source E is sent toward the curent receiving end of a section T on the left side of the figure starting from the end P of an electricity transmission that is near a joint S in the boundary of the secon T on a rail RL. A vehicle L which has wheel shafts W1 and W2 is also assumed to run in the direction arrow (a) shown in the figure. A current receiver R detects rail current in the section T. A receiver RV detects the level of the rail current from the information on the rail current that is detected by the current receiver R and outputs to a recorder LR. Whether or not insulation breakdown occured only during the vehicle passed can be easily detected by different level change as shown in the figure. Occurrence of entire insulation breakdown at a joint can be thereby predicted.

IPC: G02B6/38
Filed: 1980-08-14
Abstract: A light-conductor coupling means for coaxially connecting two optical fibres comprises two cylindrical end members, which contain the optical fibres, and a centering sleeve which receives and centers the end members with a precise fit. The centering sleeve, at its inner surface, and/or the cylindrical end members at their outer surfaces are provided with at least one spiral vent passage. The vent passage permits the air to escape when the two cylindrical end members are fitted together. The vent passage extends over the entire periphery of the inner surface so that the centricity of the arrangement is not detrimentally affected.

Title: Excitation system of induction motor
Inventor: YAMAMOTO SHOKO
IPC: H02P27/08
Filed: 1986-05-19
Abstract: PURPOSE:To shorten the rise time of flux to such a large extent that a motor is made available for operation in a short time, by increasing the exciting current command value in starting more than the ordinary value. CONSTITUTION:In order to take out exciting current command value Idsref, an exciting current command generator 17 is provided, which is driven with the servo signal Son. When the servo signal S o n turns ON, the generator 17 gives exciting current to a motor in a definite time only. As a result, the damping time constant of flux is shortened to so large an extent that the rise characteristic of flux becomes radical. The time can therefore be shortened to a large scale required from the moment the servo signal turns ON to the moment the motor becomes available for operation.

Filed: 1983-06-24
Abstract: PURPOSE:To make it possible to eliminate recording strain caused by the deflection strain of the electric field of a charge electrode by dispensing with said electrode, by injecting information recording charge voltage into an ink particle in synchronous relation to the separation timing of the ink particle by an ink particle charging means. CONSTITUTION:Pressurized ink 4 to a nozzle 1 is injected from an orifice 1a as ink column 4a which is, in turn, separated into ink particles 4b in synchronous relation to the vibration of an electrostriction vibrator 2. On the other hand, when ink particle charging voltage is outputted from an ink particle charging voltage generating circuit 8, charge corresponding to outputted voltage is injected into the ink column 4a and sealed in each ink particle 4b. When the ink particles 4b fly between deflection electrode plates 9a, 9b connected to a deflection power source 10, they are electrostatically deflected corresponding to a charged amount and an information image is formed on recording paper by deflection control. By this method, the ink particle separating region at the leading end part of the ink column is encircled while a charging electrode to which high charging voltage is applied is dispensed with and, therefore, deflection strain by the magnetic field of the charging electrode, that is, recording strain is eliminated.

Title: Double-screen television receiver

IPC: H04N5/45
Filed: 1978-09-14
Abstract: PURPOSE: To realize the insertion of the minor screen with the 1-field memory capacity by giving the 1-line sampling with every horizontal scan period to the video signals of the minor screen to write them into the 1-field memory after eliminating the front and rear ends and then reading these signals in a fixed time to insert them into the fixed position of the master screen.  
     CONSTITUTION: For video signal I of the minor screen, three lines are defined one group, and one of the three lines is sampled to be written into 1-field memory 41. In this case, for example, only 3/4 line is written by eliminating the front and rear ends of one line such as the horizontal flyback time or the like. Then the minor screen signals written into the 1-field memory are read out in the time of the 1/4 line to secure the triple clock frequency and at the fixed insertion position of the master screen. Thus if the reading is started immediately after the writing, no overlap is caused to the 1-field memory between the writing and the reading. Thus the insertion becomes possible for the minor screen with the 1-field memory capacity.
