Title: Panel fixing metal fitting
Inventor: NOTO HIROKAZU
IPC: E04H17/16
Filed: 1994-07-14
Abstract: PURPOSE:To facilitate installing work so as to improve workability by fixing the first fixing part of a fixing metal fitting in a supporting column, fixing the second fitting part in a grid panel, and arranging a notch through which a screw part of a fixing bolt is passed. CONSTITUTION:Two external thread plates are respectively slid along a rail 21 of a supporting column 2 to the optimum height, and bolts of the external thread plates are individually passed through round holes of fixing metal fittings 3 so as to be fastened by means of nuts, so that two fixing metal fittings 3 are fixed in the supporting column 2. Then, the external thread plates are slid to the vicinity of the fixing metal fitting 3 along a rail of a grid panel 1 so as to be set at the same height as notches of the fixing metal fittings 3, and the bolts of the external threads are inserted into the notches of the fixing metal fittings 3. Subsequently, the bolts are hung in semicircular parts in the lower ends of long holes, and the bolts are prevented from falling off to the outside from opened grooves, so that assembling work can be carried out without moving the grid panel 1. Hinges 43 are installed in the end parts of an upper beam and a lower beam of the grid panel 1, and adjacent grid panels 1 are connected together rotationally.

Title: Waveguide type nonlinear optical device
Inventor: IMOTO SACHIKO
IPC: G02F1/355
Filed: 1991-06-28
Abstract: PURPOSE:To obtain low output and high energy density by epitaxially growing beta-BaB2O4 on an alpha-Ba1-xSrxB2O4 substrate, thereby forming a waveguide. CONSTITUTION:The waveguide epitaxially grown with the beta-BaB2O4 is formed on the alpha-Ba1-xSrxB2O4 (where 0.04<=x<=0.10) substrate. The alpha-Ba1-xSrxB2O4 (0.04<=x<=0.10) partly substd. with Sr in the position of the beta-BaB2O4 is lower in refractive index than the beta-BaB2O4. Then, the optical waveguide can be formed by a difference in the refractive index between both if a thin film is formed by epitaxially growing the beta-BaB2O4 on the beta-Ba1-xSrxB2O4 (0.04<=x<=0.10) substrate. The propagation of light is controlled within the thin film by adopting the thin-film waveguide structure of the nonlinear optical element formed by using the beta-BaB2O4 transparent even in a UV region. The energy density is thus increased and the use of the low-output light source is allowed even if the input power is small.

Title: Manufacture of golf balls
Inventor: YAMAGUCHI TAKEHIKO
IPC: B29C35/02
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain surely golf balls of high quality with no dispersion in the initial performance, by specifying a moisture content right after cross-linking and molding the cross-linked rubber molding in the rase where the golf balls are manufactured having the cross-linked rubber molding resulted from cross- linking and molding the rubber components as component element.

This makes it possible to reproduce exactly hardness and restitution on the design. Even if this cross-linked rubber mold is subsequently wetted, deteriorating the hardness and restitution can be suppressed. As a rubber molding, it is preferred to use a mixture resulted from mixing such all constituents as a 100 weight base rubber having at least 80wt.-% of 1,4-dis-polybutadiene, a cross-linking agent 0.1-2 weight, an acrylic acid zinc base or magnesium base 5-50 weight and an inorganic filler 0-100 weight.

Title: Pwm signal generator
Inventor: INTO JUNICHI
IPC: H02M7/48
Filed: 1994-08-05
Abstract: PURPOSE:To calculate required data by an adder, which is a hardware, and generate a plurality of PWM signals at high frequencies. CONSTITUTION:The on-width data of a PWM1 signals is fetched from an 8-bit latch 3 and then it is set on an 8-bit latch 9. The bits of a free-run counter 26 which counts up at a specified clock and those of the latch 9 are compared bit by a digital comparator 27. When all the corresponding bits of the two devices agree with each other, the digital comparator 27 outputs '1' and thereby the output of a TFF 29 which performs a toggle operation inverses. The off- width data of the PWM1 is fetched from a latch 5 and then the value fetched from the latch 5 and the value of the latch 9 are added by an adder 63 and the added value is set on the latch 9. Then, bit comparison is conducted in the same manner as shown above. When all the corresponding bits agree, the output of the TFF 29 inverses. The output of the TFF 29 can be inversed also by a trigger signal to a trigger terminal 402.

Title: Facsimile device
Inventor: SHITOCHI MASAAKI
IPC: H04N1/00
Filed: 1982-10-20
Abstract: PURPOSE:To omit a paper discharge tray of a facsimile device, by controlling in interlocking with both a guide which switches the discharging destination of recording paper to an original board and an open/close control member for original slit, therefore, preventint the recording paper from entering the original slit. CONSTITUTION:When a facsimile device is set in a reception mode, the recording paper is discharged to an original board 3 from a discharge slit 8 in response to the position of a recording paper guide 10. The discharged recording paper does not go into an original slit 4 since an open/close control member of the slit 4 is closed. The original inserted through an original slit 5 is discharged through a discharge slit 22 in a transmission or copy mode. In a copy mode the recording paper is discharged through a discharge slit 9 with switch of the guide 10 to prevent the recording paper grom going into the slit 5. Thus an original board doubles a dischrge tray to reduce the space for installation of a facsimile device.

Title: Polygon mirror for laser beam scanning
Inventor: SUGAWARA BUNKICHI
IPC: G02B26/12
Filed: 1988-07-25
Abstract: PURPOSE:To make a mirror hard to break even when it is rotated fast and to obtain superior durability by forming the wall surface of a fitting hole into a ground surface where there is no fine crack layer. CONSTITUTION:The fitting hole 1b where a rotary driving shaft is fitted is bored in the center part of the polygon mirror 1 and the wall surface of the fitting hole 1b is formed into the ground surface where there is no fine crack layer. The polygon mirror 1 is pressed against the rotary driving shaft 4 across a fitting seat 5 and rotates integrally with the rotary driving shaft 4. Then when the polygon mirror 1 rotates fast, fine vibration is generated between the fitting hole 1b of the polygon mirror and rotary driving shaft 4 to apply a fine shock to the polygon mirror 1. However, there is no fine crack layer on the wall surface of the fitting hole 1b, so even if the rotational speed is increased, the polygon mirror 1 has no crack. Consequently, the glass-made polygon mirror having the superior durability is obtained.
