Patent JP-S5954027-A (JP)
Title: Magnetic recording and reproducing device
Inventor: TAKAGI NOBUAKI
IPC: G11B5/54
Filed: 1982-09-20
Abstract: PURPOSE:To control easily and accurately the position of a head, by holding rotatably the 1st head substrate containing a fixed head at the 2nd head substrate having a controllable control part and at the same time energizing the 1st head substrate toward the control part. CONSTITUTION:When a tape is loaded, the guide posts 7, 8, 10 and 11 move to the position of a solid line from the position of a 2-dot chain line. While an audio head 14 and postrecording erasion head 13 move to the positions of solid lines to the positions of 2-dot chain lines respectively. The heads 13 and 14 are fixed at a substrate 26, and the substrate 26 is attached to a rotary lever with screws 23 and 24 and a set screw 25. A rotary lever 22 can turn round a shaft 29 fixed at a rotary lever 21 and is energized toward the lever 21 by a torsion coil spring 27. The heads 13 and 14 are turned round the shaft 29 by turning a set screw 28 having its tip touching the lever 22. Thus the position of the head can be easily controlled.

Title: Arc welding method
Inventor: KITAZAWA YASUYOSHI
IPC: B23K9/127
Filed: 1986-07-15
Abstract: PURPOSE:To easily perform an automatic welding of high degrees by operating the intermediate value of the minimum values of both welding currents in an oscillation and reversing the oscillation direction at the time when the welding current detection value becomes equal to the value that the prescribed current value is added to the intermediate value. CONSTITUTION:When a welding torch 3 is oscillated up to the position set by the right end position setting circuit with its advance to the right, the position proportionate voltage outputted by an oscillation position detector 8 becomes equal to the set voltage of the right end position setting circuit, which transmits the right end position detection signal. A polarity reversal command circuit gives a polarity changing command to a motor driving circuit. A motor 5 thus drives an oscillator 6 for the direction the welding torch 3 advances to the left. With the torch 3 starting its advance to the left a current minimum value holding circuit reads a welding current detection signal and holds by detecting the current minimum value in the left advance stage of the torch 3. The left advance of the torch 3 is progressed and when the torch 3 is oscillated up to the position set by the left end position setting circuit, the left end detection circuit transmits the left end position detection signal.

Title: Induction motor
Inventor: NARITA KENJI
IPC: H02K17/02
Filed: 1990-06-21
Abstract: PURPOSE:To decrease the finished outer diameter and to eliminate gap for winding between adjacent tees by securing two rotors to a single rotary shaft through an interval, stretching a yoke across the tees and applying a winding thereon. CONSTITUTION:A rotor 2 has a single rotary shaft 9 secured with first and second rotors 8, 8' disposed in the axial direction with an interval. A stator 1 is provided with a pair or more of yokes 3 applied with a winding 5 on first and second tees 4, 4' disposed oppositely to the first and second rotors 8, 8' through a gap 6. Since two rotors are secured to a single rotary shaft with an interval where each rotor is provided with a gap in order to shorten the tees in the radial direction and the yoke is bridged between the tees and a winding is applied thereon to form a magnetic path, finished outer diameter can be shortened and since the space for winding is not required between adjacent tees, silicon steel board can be utilized effectively.

Title: Shield excavation
Inventor: KAMIYA MUNETAKA
IPC: E21D9/06
Filed: 1990-06-22
Abstract: PURPOSE:To raise the accuracy of shield excavation by a method in which by using the average directional angle value in movement of a shield machine measured by a gyro-compass during excavating period at a specific value of sierra period, a horizontal moment is given toward the same direction as the shield machine by operation of jacks. CONSTITUTION:During the moving period of a shield machine, the directional angles of the shield machine are measured at an interval of short time period (e.g. 20 seconds) by a gyro compass for every sierra period (85 minutes) and put into a computer. The data are arithmetically processed to obtain the average value of the measured values for each sierra period. A horizontal direction moment is given by operation of jacks toward the direction where difference between the average value before 85 minutes from the present time point and the direction of excavation line of the shield machine is eliminated, and the excavation is made while controllably correcting the direction. The occurrence of horizontal weaving can thus be reduced.

Title: Dyed plastic lens and its production
Inventor: YASHIRO TORU
IPC: G02B1/10
Filed: 1993-06-14
Abstract: PURPOSE:To prevent decoloring of the dyed plastic lens even if a hard coat layer is disposed on a base material and further, an antireflection layer is disposed thereon by forming a primer layer and scratch resistant hard coat layer successively from the base material side in this order on at least one surface of the base material of the dyed plastic lens. CONSTITUTION:The primer layer contg. an epoxy resin as an impact absorption layer and the scratch resistant hard coat layer are formed successively from the base material side in this order on at least one surface of the base material of the dyed plastic lens. The hard coat layer to be formed on the surface of the primer layer may be preferably a silicone resin. The reason thereof lies in that the hard coat layer harder than melamine and acrylic resins are obtainable. The epoxy resin forms a three-dimensional network structure by ring opening polymn. of an epoxy group and, therefore, the primer layer which is non meltable with heat and insoluble in a solvent is formed. Decoloring of dyes at the time of heating in forming the primer layer during the production process is thus prevented.
