Title: Gate circuit
Inventor: TANAKA KOUICHI
IPC: H03K17/16
Filed: 1984-07-09
Abstract: PURPOSE:To reduce leaked noise by suppressing a level of an input side of a switch circuit when the switch circuit is interrupted so as to reduce leaked noise and also decreasing a level difference produced at the input/output of the switch circuit when the conduction is restored. CONSTITUTION:When a pulse noise is invaded to an input terminal IN, a noise detection circuit ND detects it and transmits a signal to the output. Then a switch circuits SW1 is opened and SW2 is closed. The signal at the terminal IN is interrupted by the SW1 during this time and does not reach an output terminal OUT. Moreover, a difference between an output of a phase shift amplifier PA and a signal at the OUT appears at an output of a differential amplifier DA during this time and the difference is fed back to the input of the PA. The signal difference is mainly noise invaded to the IN and its polarity is set in a direction that an output of a buffer circuit BN and an output of the SW2 are cancelled at the input point of the PA. The input signal does not appear at the OUT for the time when the noise is incoming to the IN in this way and the noise is cancelled at the inside of the gate circuit at the same time, and the amount of leaked noise to the OUT is reduced.

Title: Freezing and refrigerating unit
Inventor: UENO AKITOSHI
IPC: F25D19/00
Filed: 1990-05-30
Abstract: PURPOSE:To prevent a drop of frozen lump-shaped frost on a drain pan by slanting the edge of a fin end of a vaporizer on its weather side so that its upper part may be directed at the lower part on the lee side. CONSTITUTION:The edge of fins of a vaporizer 2 on its weather side is slanted so that the upper part may be directed at the lower part on the lee side. Heat exchanger tubes 21 in the vaporizer 2 are laid out horizontally. Each tube 21 is connected so that refrigerant may circulate successively from the upper part of the vaporizer 2 to the lower part. At the same time, hot gas is adapted to circulate from the lower part of the heat exchanger tubes 21 to the upper part of the tunes during defrosting operation. When the vaporizer 2 is frosted and defrosted with hot gas, the edge of the fins on the weather side is slanted so that the upper part may be directed at the lower part on the lee side. This construction makes it possible to prevent frozen lumps from dropping directly on an ice drain pan 4 even when the frost is excessively accumulated and ice lamps are separated by hot gas.

Title: Congestion noticing system for store and forward exchange network
Inventor: FUJITA MUNENORI
IPC: H04L47/2466
Filed: 1993-06-14
Abstract: PURPOSE:To avoid the extension of congestion by informing sequentially congestion to a predetermined number of links only for a predetermined time among links of congestion occurrence when a called side exchange detects the congestion. CONSTITUTION:When a called exchange 203 sends a congestion notice frame, the exchange sends the congestion notice frame sequentially to a caller exchange 200 relating to all links by avoiding concentration onto node in congestion. In this case, the notice is started for links in communication and then for links not in communication. Furthermore, when a user frame is in existence in a direction of the congestion notice, congestion information is set to an in-network control header of the user frame and an exchange being a notice destination receives the congestion information at the reception of the user frame, then the transmission of the congestion notice frame is not made to the links as above. The operating rate of the congestion notice frame to the transmission band is decreased by limiting a transmission frame number per unit time by this method thereby avoiding the extension of the congestion.
