IPC: A61L9/015
Filed: 1992-12-18
Abstract: PURPOSE:To provide an excellent deodorizing effect over a long term by constituting a deodorant creeping discharge element in such a way as burying a cylindrical electrode and a heating body separated from each other in the thick wall section of a ceramic dielectric, and providing an absorbing agent or the like such as activated carbon, an odor component absorber, ozone or the like at a position downstream of the element. CONSTITUTION:A cylindrical electrode 3b and a heating body 3d are embedded in the thick wall section of a plate type ceramic dielectric 3c in such a way as separated from each other, and a linear electrode 3a is fixed to the surface of the dielectric 3c, thereby constituting a plate type creeping discharge element 3. This type of element 3 is laid in a venturi tube type restricted section 2 where the air flows after drawn with a fan 15 from the inlet 14 of an air passage 1, thereby composing a deodorant creeping discharge element 5a. Then, creeping discharge is generated at the discharge zone 4 of the element 5a, thereby decomposing an odorous substance. At the same time, heat generated with the heating body 3d is used to prevent the occurrence of a phenomenon of stopping the creeping discharge due to high humidity. The air is, then, treated with a reaction section 6 such as an odorous substance absorbing agent or an ozone gas decomposing solvent, and discharged as the clean air from a flow passage outlet 11.

Patent JP-H09181756-A (JP)
Title: Ring-shaped network constituting device
Inventor: YAMADA TSUTOMU
IPC: H04J3/08
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent a fault at one position of transmission line from being propagated not only to the abnormality of device at one station but also to the device at the other station by repeating specified data by providing a specified address generating means for pointer. SOLUTION: After an address for pointer is temporarily set by an address generating means 3c for pointer, even when the phase of input to a data constituting device A is changed, a transmission point processing circuit 3a is operated while keeping a fixed pointer value. At each constituting device, however, since the addresses for pointer are generated at random by the generating means 3c, the address different for each constituting device is set at the processing circuit 3a by the generating means 3c even when input data are continuously turned into '0' by any fault at a transmission line B1. Therefore, the received pointer value is made different from the transmitted pointer and when the continuous '0' data descrambled by a descramble circuit 1b are scrambled by a scramble circuit 3b, these data do not continuously become '0'.  Accordingly, the instability of clcok at the next constituting device can be prevented.

Title: Traveling cable device for elevator
Inventor: TAKAHASHI TATSUJI
IPC: B66B7/06
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To divide and shorten a travel cable suspending from a hanger and to cope with a relatively long elevation stroke by a method wherein the traveling cable is separated into the car side and the elevation shaft side, and an intermediate is suspended from a traveling cable hanger elevatable along with elevation of the car. SOLUTION: When a traveling cable hanger 12 is located in the middle point between an elevation shaft hanger 14 and a car hanger 10, the lengths of first and second traveling cables 11 and 13 are approximately the same each other but when the traveling cable hanger 12 is lowered to a low position, the hanger makes contact with the bottom of an elevation shaft with the same length. Therefore, the length of the first traveling cable 11 is decreased to a value shorter than the length of the second moving cable 13. Further, the moving speed of the traveling cable hanger 12 is increased to a value slightly faster then a half of the elevation speed of the car 1 in a manner to match with an amount equivalent to a lengthening elevation stroke.

The linear protrusion 354 formed in the inner circumferential direction on the inner peripheral surface of the cable hole 353 has two, preferably four lines formed at equal intervals.  As a result, it comes into intermittent contact with the outer diameter of the cable, and a labyrinth effect occurs in addition to elastic fitting, thus it is possible to attain complete waterproofing.

Title: Audio amplifier circuit
Inventor: TANEICHI YOSHIO
IPC: H03G3/30
Filed: 1991-11-29
Abstract: PURPOSE:To prevent the deterioration in the communication quality by providing a changeover means interrupting the connection at the time of a transmission start and a series circuit comprising a capacitor and a resistive element of a smoothing circuit to the audio amplifier circuit so as to avoid overmodulation at the time of a transmission start. CONSTITUTION:A capacitor 6 of a smoothing circuit is charged by a voltage resulting from a voltage of a DC power supply 10 divided by resistors 8, 9 through a switch 11 and a gate-source voltage of a FET 7 is equal to the divided voltage before the start of transmission. Thus, the resistance between the drain and source of the FET 7 reaches the resistance after the start of transmission. The switch 11 is opened as the start of transmission and when a sender applies a voice to a microphone 1, a signal is produced at an output of an amplifier 2 and rectified by a rectifier 5 to change the capacitor 6 of the smoothing circuit. Since the capacitor 6 is charged to an average voltage at the time of transmission already before the start, the charging is converged in a short time.
