Title: Method for reducing nox in waste combustion gas
Inventor: MURAKAMI NOBUAKI
IPC: B01D53/34
Filed: 1993-06-30
Abstract: PURPOSE:To efficiently denitrate waste combustion gas immediately after the start of a combustor through the normal running by forming a bypass having an ozonizer and an NOx adsorber to a passage for treated gas and bypassing the gas when the low-temp. waste combustion gas is treated immediately after the start. CONSTITUTION:A bypass 9 with an ozonizer 6 and an NOx adsorber 5 is formed to a passage 7 for the treated gas leaving an ammonia- -reducing denitrator 3 (denitrator). The treated gas contg. unreacted NOX leaving the denitrator 3 is passed through the bypass 9 when the denitrator 3 does not function sufficiently immediately after the start to oxidize the NO in the treated gas to the NO2 and N2O5 which are absorbed, and the unreacted NOx are removed. The bypass 9 is closed when the denitrator 3 functions sufficiently. Besides, a high-temp. desorbing gas is passed through the adsorber 5 while the bypass 9 is closed to regenerate the adsorbent.

Title: Preparation of film
Inventor: MATSUO TATSUKI
IPC: B29C48/08
Filed: 1979-12-11
Abstract: PURPOSE:To manufacture the film having a good slidability by a method wherein a high temperature area and a low temperature area are provided on a cooling cast roll sequentially to cystalize the surface of the film partially in case the film is manufactured by melting and extruding a thermoplastic polymer.

Title: Switching hub
Inventor: WAKABAYASHI MASAMI
IPC: H04L12/44
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To reduce the discarding of packets on a transmission line by returning a conflict signal, stopping ring pulses, or sending transmit packets back if a receiving buffer of the switching hub is stored in receive packets and overflows. SOLUTION: If the receiving buffer is stored with packets received from a terminal through DI and overflows, a Ci generating mechanism 9 inputs dummy Ci to a controller 8 through CI of Aui and the controller 8 sends a jam pattern to the transmission source through DO; and then the transmission source judges that sent packets conflict and are discarded, and resends them after deterring transmission for a certain period. Consequently, the transmission source is informed immediately of the overflow occurrence of the receiving buffer of the switching hub to deter the transmission temporarily, and then the transmission can be restarted at the time when the receiving buffer is expected to has a vacancy.

Title: Device for closing mouth of can
Inventor: HIROHAMA SHIGEHARU
IPC: B65D17/34
Filed: 1990-06-21
Abstract: PURPOSE:To secure a can from being unsealed when the side-wall of the lid undergoes expansion opening but allow a leverage piece to easily unseal it by forming a stepped hollow part in a bottom wall, by forming a cutting groove in the bottom enclosed by the stepped hollow part, and by attaching a leverage piece for unsealing at the cutting groove to the bottom enclosed by the stepped hollow part. CONSTITUTION:A stepped hollow part 2d is formed in a bottom wall 2a of a lid 2 and a cutting groove 2e is formed in the bottom enclosed by the stepped hollow part 2d so that the stretch that affects the bottom wall 2a when the side-wall 2b of the lid 2 undergoes expansion opening can be shut out from the inside of the stepped hollow part 2d. Hence breakage of the cutting groove 2e can be prevented when expansion opening occurs in the side-wall 2b of the lid 2. On the other hand, a leverage piece 4 for unsealing for the cutting groove 2e is attached to the bottom inside the stepped hollow part 2d so that by pulling up the leverage piece 4 the cutting groove 2e can be broken so as to unseal the can at the bottom inside the stepped hollow part 2d. Therefore good reliability can be achieved with respect to airtightness and the can can be unsealed easily.
