Title: Lamp lighting circuit layout
Inventor: YOHANESU HENDORIKU UETSUSERUSU
IPC: H05B41/28
Filed: 1991-02-12
Abstract: PURPOSE: To reduce electric energy absorbed by a control branch to turn a switching element on/off and electric energy consumed in a circuit and improve the efficiency of the circuit by parting the control branch with a branch which has a capacitive element. CONSTITUTION: A control branch, which has an inducing element L3 is separated with a branch D having a capacitive element. When a DC voltage source is connected to input terminals 1, 2, a high-frequency signal generating circuit P generates a high-frequency signal with a frequency (f). The high-frequency signal causes high-frequency pulse voltage with a frequency (f) on the L3 formed with a secondary minding, via a primary winding L4 in a transformer. The voltage is applied between both ends of the branch D and between a control electrode and a main electrode for a switching element S1 . A capacitance value for the D is selected to somewhat different from the resonance frequencies of the D and the L3 from the (f).  In this way, the S1 is quickly turned on/off and absorbed by the D, and so the electric energy consumed in a circuit is reduced, and the efficiency of the circuit is improved.

Title: Surface acoustic wave element
Inventor: MIKOSHIBA NOBUO
IPC: H03H9/145
Filed: 1982-03-11
Abstract: PURPOSE:To obtain a surface acoustic wave element with which the production of a comb-shaped electrode, etc. is facilitated with small delay time of a surface acoustic wave, by using an elastic matter structure in which an aluminum nitride film having orientation of a piezoelectric axis is formed on an elastic substrate made mainly of a silicon single crystal. CONSTITUTION:A silicon single crystal substrate 1 having positive delay time temperature coefficient to a surfaceacoustic wave is cut at a surface equivalent to a crystalline face (111), (110) or (001). An aluminum nitride film 2 is formed on the substrate 1 so that the piezoelectric axis of the film 2 is set vertical or horizontal to the substrate 1. Then a surface acoustic wave generating electrode 3 and a surface acoustic wave detecting electrode 4 are formed with comb- shaped electrodes on the surface of the film 2.

Title: Manufacture of coated optical fiber tape
Inventor: SAITO HIROJI
IPC: G02B6/44
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To surely identify a defective part by coloring only a defective part manufactured during the increment of a manufacturing line speed for coated optical fiber tapes up to a fixed speed. SOLUTION: Plural optical fiber 1 are collected and the periphery of these strands 1 is collectively coated with ultraviolet(UV) resin by a UV resin coating device 12. At least during the increment of a speed, UV ink is applied to the surface of the UV resin by a UV ink spraying device 5 and then the surface of the UV resin coated with the UV ink is irradiated with UV rays by a UV irradiating device 14 to cure the UV resin and the UV ink. Consequently a batch coat layer is formed on the periphery of plural optical fiber strands 1 and a colored coated optical fiber tape 2 is obtained on the surface of the batch coat layer. Thus the coated optical fiber tape of tape optical fiber cable 2 including the batch coat layer is measured about its outer diameter by an outer diameter measuring instrument 14 similarly to a conventional method and then wound up by a winding device 15.

Title: Hybrid type superconductive magnet device
Inventor: TANAKA MINORU
IPC: H01F6/06
Filed: 1981-03-20
Abstract: PURPOSE:To prevent the deviation of superconductive coils by injecting an impregnating material between the mutual superconductive coils. CONSTITUTION:The impregnating material 8 such as water, oil, wax, etc. is injected into space between the internal coil 1 and the external coil 2 in the hybrid type superconductive magnet device consisting of both coils. The characteristics of the coils can be improved because the impregnating material 8 is solidified and the internal coil 1 and the external coil 2 are not moved by electromagnetic force by lowering the temperature of the superconductive magnet device. When the impregnating material returning to a liquid or a soft body at the normal temperature is used, the temperature of either of the internal and external coils 1, 2 is returned to the normal temperature and the impregnating material 8 is removed when either of the coils is degraded. Accordingly, the coils 1, 2 can easily be exchanged.

Title: Variable speed driving device for photosensitive drum of copying machine
Inventor: KUDO YOSHIO
IPC: G03G21/10
Filed: 1987-02-20
Abstract: PURPOSE:To shorten the time for cleaning by providing a reversible motor mounted with a speed up gear mechanism to increase the rotating speed of developing rollers in contact with a cleaning liquid at the time of a cleaning stage. CONSTITUTION:A motor 50 runs backward and a 2nd counter shaft 55, i.e., 8th gear 68 is rotated counterclockwise by a 1st gear 53 and a 3rd gear 61 in the cleaning stage of the developing rollers 41, 42. The revolutions thereof rotate an output shaft 54, a photosensitive drum 3, the rollers 41, 42, and a squeeze roller 43 in the direction shown by an arrow via a 9th gear 69 and a 7th gear 67. The cleaning is thereby executed. Since the 7th, 9th gears 67, 69 are formed to the diameter smaller than the diameter of the 8th gear 68, the drum 3, the rollers 41, 42 and the roller 43 rotate at the higher speed than in the copying stage. The time of the cleaning stage and eventually the copying time over the entire part are thereby shortened. A 1st counter shaft 55 does not rotate as 1st and 3rd one-way clutches 58, 64 provided to 2nd and 5th gears 60, 65 are not engaged.

Abstract: PROBLEM TO BE SOLVED: To eliminate adherence of ink to a ruler side even if a line is drawn by using the ruler and transfer of color to a nib even if a line of another color is drawn by using the same ruler by providing a nib cover at the nib of an ink pen. SOLUTION: A cylindrical nib cover 3 is provided between a nib 1 and a nib support 2. Threads are cut between the support 2 and the cover 3.

When a line is drawn by using a ruler 9, the cover 3 is projected when a lower part is knob rotated to cover the nib 1. A ruler 9 side surface is no adhered with ink since the nib 1 is not brought into direct contact with it. Even if a line of another color is drawn by using the same ruler 9, no color is adhered to the side of the ruler 9, and further since the nib 1 of another color is covered with the cover 3, color transfer is prevented.

Filed: 1979-04-02
Abstract: PURPOSE: To raise the contactual efficiency between catalyst and gas by relaxing the drift of gas in reactior by boring great numbers of holes in the base plate of a plate catalyst in order to increase the effective surface area of the catalyst.  
     CONSTITUTION: A great number of the holes 3 of a circular, oval, square, or semicircular form, having a diameter of 1W30mm, are bored in the base plate 1 of stainless steel, etc., and then the metal plate is processed by flame spraying to roughen its surface and then coated with the catlyst component 2. If necessary, the surface in contact with the hole 3 of the base plate 1 is sloped.
