Patent JP-H10336813-A (JP)
Title: Distribution board
Inventor: MATSUSHITA TOSHIAKI
IPC: H02B1/40
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To restrain deterioration of a lead wire and attain size reduction by fitting a guide member for guiding the lead wire so as to run at least one a side surface on bus bar side of a case. SOLUTION: A guide member 8, which guides a lead wire 7 so as to run on a side surface on the bus bar side of the case of the second branch breaker 6 and a side surface adjacent to it, is constituted of resin, and its cross section is of such a shape as a roughly U-shaped trough-like part is bent at right angles in its middle part. The guide member 8 is not fixed on the case or engaged, however, by fitting the lead wire 7 inwards, attaching it on the case, and fixing the second branch breaker 6 on a box body, the guide member 8 is brought into contact with a fitted apparatus around a bus bar or the like to regulate its movement, thus it is possible to retain the lead wire 7 at the side surface of the second branch breaker 6.  As a result, the heat generated at the bus bar has difficulty in transmitting to the lead wire 7, thereby restraining the lead wire 7 from being deteriorated and attaining size reduction.

Title: Variable active filter
Inventor: KITA KOUICHI
IPC: H03H11/04
Filed: 1987-06-24
Abstract: PURPOSE: To simplify the constitution and accuracy of a variable active filter by connecting series circuits of analog switches and respective resistances in specific resistance ratio relation in parallel and performing electric feeding control over those analog switches with a binary code output corresponding to a cutoff frequency.  
     CONSTITUTION: The analog switches S 11 ∼S 44  are turned on and off according to the output C of a converter 12. Here, R 11 = R 21 =R, R 12 =R 22 =R/2...R 14 =R/2 9 . Further, R 31 =R 41 =R 0 ...R 34 =R 44 =R 0 /2 3 . When the output of a terminal 0 1  is high, the analog switches S 11 ∼S 41  are on to connect the resistances R 11 ∼R 41  to the circuit, and then RS 1 =R 11 =R=R 21 =RS 2  and similarly, RS 3 =RS 4 =R 0 . The control signal F 0  for composite resistances RS 1 ∼RS 4  is in inverse proportion to the frequency of the control signal f 0 , which is proportional to the cutoff frequency f c . Thus, the constant of an active filter is switched by the combination of fixed resistances, there is no error generated regardless of variasnce in temperature dependency or among elements, and adjustments are easy and the constitution is simplified and reduced in cost.

IPC: G01N29/04
Filed: 1989-06-22
Abstract: PURPOSE:To minimize the measure of the title device so as to be applied even to piping with small bore by regulating the feed/discharge of pressure fluid to/from each elastic expanding body according to the alternate feed/discharge of pressure fluid to/from each locking means, thereby performing straight and/or curved travel. CONSTITUTION:In case of obtaining travel along the curved part of piping, pressure fluid is fed/discharged alternately to/from each locking means 3, as well as the feed/discharge of the pressure fluid to each elastic expanding body 10 by a feed/discharge pipe 38 is changed, that is, when the pressure fluid is fed to one elastic expanding body 10, the application of the pressure fluid is restricted to the other elastic expanding body 10. As only one elastic expanding body 10 is thus expanded, a travel device is curved along the curved part of the piping with the elastic expanding body 10, positioned on the side not receiving the application of the pressure fluid, placed inside. Elastic members 14 disposed surrounding the elastic expanding bodies 10 constrain the bending of the elastic expanding bodies 10 expanded by the application of the pressure fluid, and the curvature is thereby warranted.

Title: Vertical type grinder
Inventor: TANAKA SHINSUKE
IPC: B02C15/04
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the air leaked from the outside being infiltrated into a vertical type grinder, even when a carrier following a forced discharge type damper is an open-type belt conveyor, and to continue a stable operation state for a long time by connecting the said damper with the discharge port of the vertical type grinder. CONSTITUTION:A forced discharge type damper 100A is constituted so that the lower end of a passage 107 is closed by the flaps 100a, 100b when a raw material is not present in this passage 107. A cam 106 is rotated by driving a motor. The levers 104, 104 are intermittently turned by the cam 106. The flaps 100a, 100b alternately open and close the lower ends of the passages 107, 107. Movement of the levers 104, 104 is controlled by the shape of the cam 106 so that either of the upper and lower flaps 100a, 100b is surely closed. It is prevented that both flaps are made to an opened state by the flow of a raw material as shown in a weight type damper and that the atmospheric air flows backward into the vertical type grinder at the negative pressure and that the stable operation of the mill is inhibited. Air sealing is nearly completely achieved. Since a carrier following the damper is formed of an open type, the cost of equipment is reduced and maintenance is enhanced.

IPC: B29C45/00
Filed: 1978-12-18
Abstract: PURPOSE:To eliminate waste of energy and to make the device simple, inexpensive and improved in productivity by inserting the piston rod into a hole in the bracket secured to a movable platen and connecting the pnerumatic cylinder and the air vent in the mold by a pipe. CONSTITUTION:When it is attempted to move the mold from the mold opening position to the mold closed condition, the movable platen 4 moves in the direction A while the movable die 6B is brought into tight attachmebt against the fixed die 6A to close the mold 6. Concurrently with this movement, the bracket 11 secured to the movable die 6B abuts against an adjusting means 12 to let the piston rod 10 move in the direction A, causing pressure reduction in the pneumatic cylinder 9. Since the charge-over valve 14 remains at its neutral position during this operation, the lowest pressure is reached when the mold 6 is closed. Upon completion of mold closure, the change-over valve 14 is operated so that air in the mold is sucked out from the air reservoir 6D in the movable die 6 through an air vent 6E and a pipe 13, whereby pressure in the cavity 7 is reduced to promote inflow of the resin injected from a spool 8.

Filed: 1994-06-17
Abstract: PURPOSE:To provide a suspension controller that is able to secure good riding quality and steering stability in quickly responding to lateral acceleration crosswise acting on a car in time of traveling. CONSTITUTION:When a lateral acceleration variation is plus, an extension side of a buffer at the body right side is set to a hard characteristic and a contraction side of the buffer at the body left side to the hard characteristic, respectively (steps S6 and S7), and when this variation is minus, the contraction side of the buffer at the body right side is set to the hard characteristic and the extension side of the buffer at the body left side to the hard characteristic, respectively (steps S8 and S7). In the case where a car turns anticlockwise, right force acts on the body and rolling is started, right inclining force is surely checked, preventing any inclination of the body, and when returning force gets acting on the body, it comes to gradually absorb this returning force, so that a sudden return of the body is prevented from occurring and thus good riding quality and steering stability are securable in this way.
