Title: Plating method for separating pawl for seedlings with soil in rice-transplating device
Inventor: ISHIDA ISAO
IPC: A01C11/02
Filed: 1980-04-24
Abstract: PURPOSE:To form plating layers which do not produce any level change by inserting a separating pawl for seedlings in a rice-transplating device into a cylindrical body which loosely fits said pawl, in a manner as to project only the leading end  part and plating together with the cylindrical body. CONSTITUTION:A separating pawl 1 is inserted into a cylindrical body 6 having a bore fitting loosely thereto, in such a manner that its leading end 2 projects to the upper part. In this state, the pawl together with the body 6 is sunk in a plating cell and is thereby plated. The formed plating layer 4 has no level change at all. This is because the leading end 2 part exposed perfectly to the outside is sufficiently thickly plated (a), but the part alongside the end part 7 of the body 6 is slightly thinly plated (b), and further the inner part is gradually thinly plated (c). Since there are no level changes in the pawl 1, damaging the stalks and leaves of seedlings is prevented.

Title: Non-lapped concentrated winding induction motor
Inventor: NAGASAKA NAGAHIKO
IPC: H02K17/16
Filed: 1989-03-07
Abstract: PURPOSE:To automate winding work of stator winding by employing concentrated stator winding and non-lapped concentrated rotor winding where the rotor winding is splitted into two sets of three-phase winding constituting a cage winding. CONSTITUTION:A stator 1 comprises coils A, A' facing each other and connected in series in reverse direction and similar coils B, B' constituting a two-phase two-pole concentrated winding. A rotor 2 comprises two sets of three-phase cage winding contained in six grooves. Rings for short-circuiting the bars 21 contained in the grooves of the rotor 2 are classified into two sets and every three bars are short-circuited through a short circuit plate 22 in order to prevent crossing of third harmonic with the rotor winding. In other words, since three sets of three-phase cage winding are arranged with electrical angle of 120 deg., the third harmonic produced by the stator 1 has wave length corresponding to 120 deg. and thereby the third harmonic does not cross with the winding. By such arrangement, loss due to parasitic torque is not produced.

Title: Switching and displaying unit for tuning audio level
Inventor: MATSUKI KOUJI
IPC: H03J1/04
Filed: 1979-05-04
Abstract: PURPOSE:To use one indicator as two indicators of audio level and tuning, by using induction hum produced through touch of a finger on the knob at tuning. CONSTITUTION:Since no input is fed to the inverter at all times, the output is at high level, the electronic switch S1 is operative, the contact IC3a is closed, the signal voltage from the audio level voltage production circuit V1 is fed to the indicator L via the LED driver IC5 and the LEDs having the number proportional to the audio level voltage are illuminated. With this state, when a finger tip is touched on the tuning knob T, the hum induced through the humanbody is fed to the hum detection and amplifying circuit G1 to cause the inverter at high level. The contact IC3b of the electronic switch S2 is closed and the contact IC3b is open. The indicator L is connected to the tuning voltage generating circuit V2 to illuminate the LEDs having the number proportional to the tuning voltage. Thus, since one indicator can be used as two objectives, the operation can be simplified.

Title: Two probe flaw detection method for piping
Inventor: ARAKAWA TAKAHIRO
IPC: G01N29/06
Filed: 1981-04-13
Abstract: PURPOSE:To permit flaw detection of defects such as cracks generated in a piping despite the presence of penetration beads and ruggedness on the inside surface of the piping by bringing two pieces of probes having the same radius of curvature of the contact parts as that of the outside circumference of the piping into contact with the outside circumference of the piping. CONSTITUTION:With a straight line which intersects with the ultrasonic beam direction X1 of an ordinary probe 3 at an angle beta and passes through the incident point P1 after working as a symmetrical axis, said probe is worked to the curvature of a radius R. Such probes 3 are disposed symmetrically on the right and left on a piping 1 with the axial line as a center, and one of these is used as an oscillator and the other as a receiver. The probes 3 are scanned in such a way that the mutual position relations in the axial line direction and circumferential direction of the piping 1 do not deviate, whereby flaw detection is accomplished. The advancing direction of the ultrasonic wave beam 5 of this case is in the direction parallel to the axial line direction of the piping 1. Hence, despite the presence of a penetration bead near the crack 2' on the inside circumferential surface of the piping, only the crack 2' is detected accurately without detecting this.
