Title: Bearing device for transmitting rotation
Inventor: YAMAZAKI SHINOBU
IPC: F16C29/06
Filed: 1986-12-16
Abstract: PURPOSE:To enable the whole structure to be simplified, by enabling the rotation of a guide member transmitted by the engaging action between a bearing body and a shaft member, and forming the guide member and the bearing body into an incorporated structure. CONSTITUTION:Bearing bodies 3 are arranged right and left so as to be opposite in a housing part 2, and live ball parts 5a arranged right and left in a ring shape and housed in two resin-made retainers 4 respectively are made to be penetrable by through holes 6, and releasing ball parts 5b are enabled to be retained by recessed parts 7. Thus, by the engaging action between the live ball parts 5a of the bearing bodies 3 and the engaging rolling grooves 16 of a shaft member 15, a guide member 1 is enabled to transmit rotation and to guide the linear motion along the shaft member 15. Accordingly, the guide member 1 and the bearing bodies 3 form an incorporated structure, and hence the simplification of the whole structure as well as the miniaturization can be achieved.

Title: Production of plate for building
Inventor: HOSONO AKIHIRO
IPC: B21D5/08
Filed: 1986-12-18
Abstract: PURPOSE:To reduce a production cost by forming the engagement part of the final shape in V-shaped or reverse V-shaped cross-section on a plate by the roll forming at the initial stage and forming in order the remaining part by the roll forming at the middle and final stages. CONSTITUTION:The engagement part P3 of V-shaped or reverse V-shaped cross- section consisting of an orthogonal piece P3a and inclined piece P3b is subjected to roll forming for the plate P0 to be formed. In this case, the forming is gradually executed and completely up to the final shape as well. A crest-like part P2 and bottom part P1 are then formed by the roll forming at middle and final stages. In this case, the engagement part P3 passes through the gap between rolls to prevent the breakdown, At the final stage of the roll forming the side part inclined face P2a and end part engaging part P3' of the plate P0 to be formed are formed. Since the work is executed only by the roll forming in a simple shape and the change in the shape and dimension of a product can be done by the partial change in the roll equipment the production cost is reduced.

Title: Reel servo controller
Inventor: YAMAMOTO RYOHEI
IPC: G11B15/46
Filed: 1986-12-18
Abstract: PURPOSE:To keep the tape moving speed constant against the blank tape by calculating the tape quantity at the take-up reel based on the driving speed detection value of both reels so as to control the take-up side reel motor. CONSTITUTION:The drive speed of the supply and takt-up reels 11, 12 is detected by a magnet and detection heads 13, 15 and 14, 16 respectively and a tape residual operation section 17 calculates the tape residual time of the reel 11 based on the detected value and displayed on a display section and the tape quantity time of the reel 12 is calculated. An object control angle speed changed in response to the radius of the reel 12 is read from a built-in memory of a blank part servo control section 19 from the calculated value. Then the motor 26 is fed-back and controlled depending on the difference between an object controlling angle velocity and the measured valve of a tachometer of the reel motor 26 for the reel 12 via the frequency generator 27 and the tape moving speed is made constant. Thus, the tape moving speed is kept constant even to the blank tape without recording.

Title: Magnetic circuit device
Inventor: URABAYASHI MASAAKI
IPC: H01F3/00
Filed: 1986-12-16
Abstract: PURPOSE:To suppress the leakage of a magnetic flux from a magnetic circuit and to improve efficiency by constituting the circuit with a magnetic material having a magnetic anisotropy by the effect of the reverse magnetostriction on its surface layer. CONSTITUTION:An auxiliary magnetic pole 1 and a magnetic substrate 4 are made of a ferrite and they have an SiO2 film 9 formed in a sputtering method at high temperature on their surfaces. In a magnetic head constituted like this, the auxiliary magnetic pole 1 and the magnetic substrate 4 near the SiO2 film 9 receive a tension caused by the SiO2 film 9 because of the difference between thermal expansion coefficients and the magnetic anisotropy is induced in the surface parallel with the surface of the SiO2 film 9 by the effect of the reverse magnetostriction. When the magnetic flux flows in the magnetic head, the magnetic flux is easy to flow in a direction parallel with the surface of SiO2 film 9 because of the magnetic anisotropy but not easy to flow in a direction perpendicular to the surface of the SiO2 film 9. Thus the leakage of the magnetic flux from the magnetic material can be suppressed and the efficiency of recording and reproducing the magnetic head can be improved.

Filed: 1988-11-30
Abstract: PURPOSE:To use one line as two independent lines for order-wire system by code-converting an input signal to on order-wire line into an adaptive differential PCM signal, and transmitting it to an existing device data channel. CONSTITUTION:When another voice signal (b) is outputted besides from a voice circuit 2 while the voice signal (a) is outputted from the voice circuit 1, this voice signal (b) is turned into a linear PCM signal through a PCM code circuit 4 and a PCM/LINEAR conversion circuit 8, and is inputted to an adder 10. The adder 10 adds this linear PCM signal and the linear PCM signal from the above-mentioned conversion circuit 12, and outputs them to a LINEAR/PCM conversion circuit 14. An adaptive differential PCM code circuit 18 converts the inputted PCM signal into an AD PCM signal (d) of 32kb/s, and outputs it to a multiplex circuit 20. Accordingly, two independent order-wire lines can be accepted by one line of the service data channel of 64kb/s.

Title: Shaft of golf club
Inventor: YONEYAMA MINORU
IPC: A63B53/10
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a golf club shaft having elastic stability and giving a greater distance. SOLUTION: Six to 10 nickel titanium fibers 6 are interposed between carbon fiber layers 4b of a golf club shaft 2 formed by laminating concentrically two or more carbon fiber layers 4a and 4b. The nickel titanium fibers 6 are arranged in parallel with and around the axial direction of the shaft at an equal interval.

Abstract: PURPOSE:To simply surely change valve timing or valve lift by providing a contact fulcrum part for a rocker arm shaft in a sub-rocker arm while providing in the rocker arm shaft an eccentric part which can be changed over to make contact with or part from the contact fulcrum part by the rotation of the rocker arm shaft. CONSTITUTION:When an eccentric part 16 is set not to contact a contact fulcrum part 15 of a sub-rocker arm 13 by rotating a rocker arm shaft 8, the sub-rocker arm 13 is swingably pivoted only about a pivot pin 14 for both main rocker arms 12 by a high speed cam 11 without being swingably pivoted about the fulcrum of the rocker arm shaft 8. Thus, the swingable pivoting of the sub-rocker arm 13 is not transmitted to an intake valve 3 and the intake valve 3 is operatively opened and closed by a low speed cam 10. On the other hand, when the eccentric part 16 is set to contact the contact fulcrum part 15, the sub-rocker arm 13 is swingably pivoted about the fulcrum of the rocker arm shaft 8 by the high speed cam 11. The intake valve 3 is operatively opened and closed by the high speed cam 11.
