Title: Condensing unit
Inventor: KAWAI MASAFUMI
IPC: F25D19/00
Filed: 1990-01-19
Abstract: PURPOSE:To prevent low temperature refrigerant gas returned from a condenser from making contact with air which has been heat exchanged at a condenser and heated during said low temperature refrigerant gas passing through a low pressure side refrigerant pipe, and further prevent the amount of refrigerant circulation from being reduce and freezer oil from being deteriorated by providing a windshield between the low pressure side refrigerant pipe of a condensing unit and a fan motor. CONSTITUTION:Once a condensing unit is operated, cold air refrigerant gas returned from a condenser enters a compressor 2 after passing through a low pressure side service valve 9 and further a low pressure side pipe 11 and is supplied to a fin condenser 3 as high temperature high pressure gas. On the other hand, a fan 6 is rotated by the actuation of a fan motor 5 to suck air which air is then heat-exchanged with the high temperature high pressure refrigerant gas through the fin condenser 3 and thereafter the air is allowed to flow in the direction indicated by an arrow. Thereupon, the air collides with the windshield 12, and is changed in the direction of its flow and hence is prevented from making contact with the low pressure side refrigerant pipe 11. Thus, temperature of the low temperature refrigerant gas sucked into the compressor 2 is prevented from being raised and the amount of refrigerant circulation is not reduced.

Abstract: PURPOSE:To attain message collection without aborted data by a minimum buffer memory by dividing plural line devices into plural groups when data from the plural line devices connected to a bus are collected and setting a data transfer quantity in a group to the bus capacity or less. CONSTITUTION:At least one of bus path changeover means 21-2m connects plural high speed transmission buses H1-Hm in series between an input and a 1st output. A control means 40 adds the transfer quantity of the bus connected to the input of the changeover means 21-2m in the order of series connection, and when there is any of the changeover means 21-2m in which the sum is equal to the bus capacity or less and the value adding the bus transfer quantity of the 1st output to the sum is larger than the bus capacity, the input of the changeover means 21-2m is connected to the 2nd output by the control. The number of transfer paths connecting the 2nd output of a line concentration means 51 is decreased when the data transfer quantity is reduced. Thus, the concentrator 51 is made efficient and high speed transmission is attained without limiting the number of terminal equipments.

Abstract: PURPOSE:To obtain the magnetic field of the desired size for the magnetic field of a magnetic roll outer periphery by eliminating a magnetic path to go around the internal part of a permanent magnet to be generated at a boundary part and increasing a magnetic flux to form the useful magnetic field of the magnetic roll outer periphery. CONSTITUTION:Since for a magnetic roll 32, a superconducting member 30 is provided between respective magnetic poles of a permanent magnet 10, the infiltration of a magnetic flux into the internal part of a superconducting member 30 is stopped by a Meissner effect which is the unique effect held by the superconducting material and the magnetic path to be completed in the internal part of the permanent magnet 10 and the superconducting member 30 is not formed. Consequently, a magnetic flux is discharged to the external part of the permanent magnet 10 and the superconducting member 30, and the number of magnetic fluxes to form the magnetic field of the outer periphery of a sleeve 12 is increased. Thus, the outer periphery of the sleeve 12, namely, the magnetic field of the outer periphery of the magnetic roll 32 becomes stronger and a developer 16 of the constant quantity can be conveyed and supplied stably in a photosensitive direction.

Title: Input selection display device
Inventor: UMEMOTO KATSUHIKO
IPC: H04B1/16
Filed: 1984-01-27
Abstract: PURPOSE:To prevent a misdisplay by switching an input selection swtich to a radio input after switching a radio receiver to FM or AM and at the same time inactivating a circuit which erases the FM or AM display by the multing signal given drom a PLL synthesizer. CONSTITUTION:For instance, an FM switch 2e of a switch group 7 is operated when a PLL IC6 is set in an AM mode and an input selection circuit 1 is set at a tape position. Then a muting signal is delivered from the circuit 6, and a transistor TR11 conducts. Then the circuit 1 selects a radio input, and an FM/ AM switching signal 6c of the circuit 6 is delivered. When an FM/AM power supply switching circuit 10 is switched to an FM mode, and the muting output is set at zero to turn on an LED4e of FM. A diode 12 inactivates a citcuit which erases the FM/AM display to inhibit the conduction of the TR11 when the circuit 1 selects a radio input. In such a way, it is possible to avoid a misdisplay caused when an FM or AM changeover switch is operated.
