Title: Delayed neutron detector of fast breeder
Inventor: MARUYAMA TOMIYOSHI
IPC: G21C17/07
Filed: 1990-03-29
Abstract: PURPOSE:To efficiently detect delayed neutrons with high reliability by providing a sampling pipe to be inserted under a primary sodium liquid level, a sampling pump, a sampling tank, and a neutron detector. CONSTITUTION:The delayed neutron detector 20 is constituted of the sampling pipe 23 and the sampling pump 24 in its detecting unit 21 as well as the sampling tank 25 disposed upper than the liquid level of the primary sodium, the neutron detector 26 and a neutron moderator 27. The primary sodium is sucked into the sampling pipe 23 by the operation of the pump 24 and is sucked up into the tank 25. The thermal neutrons which are released from this sodium 7 and are transmitted through the wall of the tank 25 and the moderator 27 is measured by a detector 26. Fission products flow into an intermediate heat exchanger along the flow of the sodium 7 when the fuel cladding pipe in the fuel assembly ruptures in a reactor core 4. The delayed neutrons released during this time are sucked up into the tank 25 and are detected by the detector 26.

Title: Information recording medium reproducing device
Inventor: ARII KOJI
IPC: G11B27/10
Filed: 1989-03-29
Abstract: PURPOSE:To select and reproduce an operation intended by an application producer by operating a command specifying means by the user by recording a bit of command interpreting information to an information recording medium, interpreting a command discriminator specified by the command specifying means with the command interpreting information and running the command. CONSTITUTION:In order to interpret and run the command discriminators 21a and 21b specified by the user using bits of command interpreting information 20a and 20b, the operation intended by the application producer is selected and reproduced by the user using the command specifying means 19. Consequently, even with the same command discriminators 21a and 21b, if a disk 11 to be reproduced is different, the bits of command interpreting information 20a and 20b in an information recording medium 18 are different, so that complex and diverse operations can be realized even with a limited number of command discriminators 21a and 21b. In addition, for the application producer, an original command defined by himself as a processing operation can be produced. By this method, the operation intended by the application producer is selected and reproduced by the user using the command specifying means 19.

Title: Defrosting device for air conditioner
Inventor: MATSUBARA MITSUNORI
IPC: F25B1/00
Filed: 1989-03-29
Abstract: PURPOSE:To enhance comfort and reduce running cost during dehumidification by detecting an indoor intake air temperature and a blowoff air temperature during dehumidification operation, heating the temperature of air discharged from a vaporizer with a hot water coil, and controlling the flow rate of hot water so as to obtain said temperature. CONSTITUTION:When dehumidification operation is instructed, an outdoor microcomputer 39 output commands so that an electric expansion valve 24 may be opened in proportion to its frequency. An inverter power circuit 40 operates an inverter compressor 20 at a minimum frequency. In this case, an intake temperature and a blowoff temperature are detected by an intake temperature sensor 26 and a blowoff temperature 31. When the detected temperature is input into an indoor microcomputer 38 by way of a temperature detection circuit 37, it is output to a boiler 35 so that the boiler 35 starts its operation. At the same time, the microcomputer 37 outputs an ON/OFF command to a flow rate control valve 32. This ON/OFF command varies the opening of the flow rate control valve 32 so that a differential temperature DELTAT may be 0, heating a low humidity and low temperature air discharged from a vaporizer 27, thereby performing dehumidification operation. It is, therefore, possible to enhance the comfort of the operation and reduce running cost as well.
