Abstract: A device is disclosed meant to perform evaporation of insecticides, perfumes or the like, wherein the degree of evaporation is controlled by a moving cap (9) which makes up the regulating element (6), which is meant to produce a chimney effect in the upwards motion of the generated vapor, so that this effect enhances evaporation, while regulation is achieved by the different heights at which moving cap (9) can be placed. This displacement is performed manually by moving guide (13) inside inclined track (10).

Abstract: There is provided a circuit board cabinet which is capable of more reliably preventing flames of a fire in a shelf from spreading to external devices, without degrading cooling capability thereof. Flames of the fire occurring in the shelf rise within a slot, pass through a shield plate, and then enter a heat shield unit. In the heat shield unit, the flames are first blocked by a heat shield plate and substantially reduced in force while passing through holes formed through the heat shield plate. Portions of the flames which were not blocked by the heat shield plate reach a top board of the unit after passing through the holes, where they are reduced. Since there is a predetermined distance between the heat shield plate and the top board, the flames having passed through the heat shield plate spread horizontally to some extent and then reach the top board. Therefore, it is possible to reduce the force of the flames sufficiently by the top board.

Abstract: Disclosed is an ATM switching apparatus capable of reducing a probability an IAM acceptance being rejected due to a difference in bandwidth acquiring algorithm. The ATM switching apparatus is constructed such that when receiving an IAR due to the difference in bandwidth calculation algorithm for the IAM indicating a use of a certain VPC, a calculated bandwidth value is set in an estimated free bandwidth value about the VPC within a bandwidth management table, a value given by Calculation Bandwidth Value/Free bandwidth Value is set in a ratio, and the VPC is selected by using not the free bandwidth value but the estimated free bandwidth value (=Free Bandwidth Value×Ratio) when transmitting the IAM. It is another contrivance that when the free bandwidth value changes, the estimated free bandwidth value is also changed to establish “Estimated Free Bandwidth Value=Free Bandwidth Value×Ratio” without changing the ratio.

Abstract: A load monitoring apparatus has a structure that the electric-power value of a motor is sampled in response to a sampling signal, the sampling cycle of which is changed at a predetermined recursive number. Moreover, the electric-power value is calculated in accordance with a result of the sampling is subjected to an absolute-value range and a relative-value range which is determined in accordance with the previously calculated electric-power value so as to determine an abnormal load of the motor. The sampling cycle is elongated in predetermined steps to correspond to the characteristic of, for example, a reduction gear until a stable driving state is obtained so that an abnormal state of the load such that the load is gradually increased or decreased is detected in accordance with the relative-value range before the abnormal state exceeds limits of the absolute-value range.

Abstract: A transmission system for transmitting a data signal with an analog passband signal through a analog transmission line. The data signal is transformed to a signal representing a descrete data signal point in a vector signal space. The analog passband signal is transformed to a base band signal, and the base band signal is superimposed on the signal representing a descrete data signal point. A signal representing the superimposed data signal point is modulated and transmitted through the analog transmission line. In a receiver, the data signal point is decided from the signal representing the superimposed data signal point, and the superimposed base band signal is extracted by subtracting the decided result from the signal representing the superimposed data signal point. The base band signal is transformed to the analog passband signal. A portion of information carried by the analog passband signal may be converted to a digital signal, and the digital signal is multiplexed with the data signal.

Abstract: A pseudo-noise generating apparatus capable of starting a pseudo-noise sequence from an arbitrary phase using compact processing circuitry. Tap selection patterns corresponding to a plurality of phase shift amounts are stored in advance in a ROM. By giving a phase shift amount to the ROM and setting the corresponding tap selection pattern in AND gates, the pseudo-noise sequence generated by the pseudo-noise generator is shifted in phase, and is loaded into a shift register. After setting a new phase amount in the ROM, the contents of the shift register are transferred into a shift register in the pseudo-noise generator. By repeating this operation, the desired phase shift is accomplished as a sum of a plurality of phase shift amounts.
