Title: Constituting materials of road face zone
Inventor: NAKAMURA YUTAKA
IPC: E01F9/512
Filed: 1994-05-06
Abstract: PURPOSE:To prevent the traffic accidents from being happened by dotting surface of a belt zone so as to line up a number of protrusions as a unit with a certain width and making the surface to form a rugged face. CONSTITUTION:A plurality of protrusions 2a, 2b having circular, diamond, or quadrangular planes are formed as a unit at the face of the surface course layer 1a made of abrasion-resistant and heat-proof materials to make a rugged surface. And the surface course layer 1a is laminated with an adhesive material layer 1b made of a material which can be welded by baking to the asphalt road face and to form a belt zone 1 stuck on the face, having the broadwise distance as wide as the width corresponding to the center line of the road. In such a constituting material of a road face zone, when vehicles run on the belt zone or run out thereof, a number of protrusions 2a, 2b,... come into contact with the tires and the vehicles vibrate due to the protrusions and generate noises. And hence, it prevents drivers from dozing while driving or gives psychological pressure to force them to pay attention not to overtake recklessly.

IPC: H02N2/00
Filed: 1988-05-13
Abstract: PURPOSE:To generate ultrasonic oscillation effectively, by installing a plurality of piezoelectric elements to a base elastic body to which cantilever elastic bodies are provided. CONSTITUTION:For an ultrasonic motor a cylindrical fixed section 2 as a base overhangs to the upper inner wall of a hollow motor body 1 consisting of the 1st and 2nd housings 1a and 1b. An annular base elastic body 3 is fixed at its screw hole 3a to its fixed section 2 with bolts 4. These bolts 4 fix the fixed section 2 and base elastic body 3 in the position of its nodal points when standing wave is generated to the base elastic body 3. On the base elastic body 3 from the neighborhood of the part where there are nodal points in every cycle, four cantilever-shaped elastic bodies 5 are radially spread onto the base elastic body 3. Between the fixed section 2 and the base elastic body 3 a piezoelectric element 6 of a thickness oscillation mode is contactingly provided, which excites bending vibration in the upward and downward directions to the above cantilever-shaped elastic bodies 5. Ultrasonic oscillation can thereby be generated effectively to the elastic body 3.

Title: Clad type positive plate
Inventor: TSUBOTA MASAATSU
IPC: H01M4/16
Filed: 1982-07-06
Abstract: PURPOSE:To improve life and high rate discharge performance of a battery by filling an organic high molecular material having ion conductivity in voids between granulated lead powders. CONSTITUTION:A paste obtained by kneading lead powder and dilute sulfuric acid is formed in a granular shape with a granulating machine. Ball-shaped granules having a particle size of 0.1-1.0mm. are preferable to uniformly fill them in a tube, and to keep granules in contact with other granules, and to form gaps for electrolyte path in an active mass layer. After drying, granules are mixed with an organic high molecular material, and they are filled in a tube and formed to obtain a clad type positive plate. Ion exchange resin such as cation or anion exchange resin is preferable as the organic high molecular material. It is important that a mixing amount of the ion exchange resin does not exceed the amount necessary for filling the void volume between granules. Even if binding action of granulated active masses is decreased by repeated charge-discharge cycles, breakdown of them is prevented by filled ion exchange resins.

Title: Erase pulse application method for picture display unit
Inventor: GAKOU NOBUKATSU
IPC: G09G3/30
Filed: 1977-09-30
Abstract: PURPOSE:To simplify the circuit constitution as well as to reduce the cost by applying the bipolar erase pulse with the same timing and every plural units of the electrode line. CONSTITUTION:The luminance of the memory equipped EL panel is substantially proportional to the number of the maintenance pulse after writing, so no effect is given as long as the numbers of the maintenance pulses are equal between writing selection pulse WP and the erase pulse even if the time interval differs between WP and the erase pulse. In this connection, the timing of application for the erase pulse is made identical between plural units of the scan-side electrode, thus simplifying the structure of erase pulse timing signal generating circuit 16. The waveforms to be applied to picture element (1, 1) and (1, 15) of matrix panel MP featuring the picture display speed of 15 sheets/sec. are shown like (a) and (b), and the application period during which bipolar erase pulse CP and WP are given to the odd-numbered electrode lines V1, V3... V15 of MP are shown by OW and OE. Thus, the writing is performed to 8 pieces of lines V1, V3... between maintenance pulse a1 and a2. In this case, the CP is applied with the same timing (between maintenance pulse a31 and a32) to these 8 pieces of the line.

Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the damage of a master tape and to prolong the service life of the tape by forming an end part of a guide member provided near a capstan for the purpose of separating the traveling tape from the capstan into a round shape and also setting a gap with the capstan to a specified dimension and downward. SOLUTION: The end part 28a of the guide member 27 on its tape guide surface 28 near the capstan 15 is formed into a circular-arcuate shape having a radius in extent of 1.0-5.0 mm, and in this case, an effective length of an adjacent part 27a of the guide member 27 to the capstan 15 is set to 5-20 mm, while the gap (b) between the capstan 15 and the guide member 27a is set to <=0.4 mm. Consequently, even when a joint part of the master tape 1 is passed over the guide member 27, the tape 1 is smoothly traveled, while because of restraint of the diminished gap, a negative pressure to be worked on the tape 1 is reduced, so that scraping and rubbing of a back coat surface is reduced, then the damage of to the master tape 1 is surely reduced.

Title: Washing method for ion exchange resin bed
Inventor: SUGIYAMA TAIZOU
IPC: B01J49/00
Filed: 1980-08-29
Abstract: PURPOSE: To wash an ion exchange resin efficiently with a smaller amount of water by a method wherein a vacant space is formed in an ion exchange column by draining water, then contaminants are washed out while applying a pressure and preventing air from flowing out, and back wash waste water is discharged under pressure.  
     CONSTITUTION: Water is drained from the ion exchange column 1 through an intermediate draining pipe while introducing air into the column 1 via an upper part to form the vacant space 4 at an upper part of the interior of the column 1. Then, while introducing air from a lower part of the resin bed and discharging the air through the upper part, the resin bed is scrubbed to strip off the contaminants from the surfaces of the resin. Thereafter, when the resin bed is back-washed by introducing the back wash water through the lower part of the resin bed while preventing the air in the column 1 from flowing out, the contaminants are washed away and the back wash waste water flows into the space 4 to apply a pressure to the interior of the column 1. Then, when draining is conducted by opening a valve for the draining pipe 3, the back wash waste water is discharged at a stroke. Accordingly, the ion exchange resin bed is washed efficiently.

An n type fifth region 29 is shaped to the region 23 under the electrode 27. Consequently, displacement currents flow into the short-circuit section of the end section of the region 24 because structure in which the cathode 26 covers the concave section of the region 24 and the region 23 and the region 24 are short-circuited is formed. Accordingly, the resistant quantity of dV/dt is improved because the currents flow toward the cathode 26 from the region 23.
