IPC: F27B21/14
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To stably hold the level of a returned fine tank in a given target range through simple tuning. SOLUTION: Based on a present level X (S2) of a returned fine tank and a change amount σ(S4) of a level, a returned fine using ratio varying amount ΔQ is determined at S45.

CONSTITUTION:A refrigerant discharged from a compressor 1 is condensed by a condenser 6 or 12, and is reduced in a pressure by means of a motor-operated expansion valve 13 or 8 for circulation, and freezing is effected through the action of a heat pump. In which case, an opening control means 52 controls the opening of the indoor motor-operated expansion valve 13 so that the superheat of a refrigerant detected by a detecting means 51 is adjusted to a specified value, and freezing is effected according to a freezing load in a chamber. In this case, when it is discriminated by a discriminating means 53 that the degree of superheat exceeds a given set value, the opening of the motor-operated expansion valve 13 or 8 is varied to the opening side by a given value by an opening forced set means 54. Thereafter, the opening is maintained as it is for a specified time, and a freezing state is maintained on the wet side to maintain freezing capacity in an indoor heat exchanger 12 at a high value. This constitution enables execution of high-efficient control of the degree of superheat.

Filed: 1980-12-01
Abstract: PURPOSE:To discriminate ineffective and effective record length in a record unit, by taking the logical record length as one unit and adding a horizontal parity check (LRC) byte. CONSTITUTION:When records A and B are collected in mixture, CPU11 generates a horizontal parity check (LRC) byte based on the record length and stores it to a memory 12. Even if an error is detected at an A1 record, a B1 record checks the LRC byte of the 2nd block and if it is normal, the B1 record is made effective. Inversely, if the record B1 of the 1st block has an error, when the A1 record before it is normal, the LRC byte of the B1 record is checked and only the B1 record is made ineffective.

Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce characteristic change due to using atmosphere and to prevent generation of crossover when used in an electrochemical element by including a large amount of the OH group in an inorganic material to conduct proton conductivity. SOLUTION: As a proton conductor, an inorganic material is used. The inorganic material is not specifically limited if it allows introduction of the OH groups. From the standpoint being used as an electrochemical element such as a fuel cell, use of an amorphous compound containing SiO2 or P2O5 of an insulating and high resistance material is preferable. A material in which the content of the OH group in the inorganic material is 1% or more is selected. A dense proton conductor is desirable, and when used as an electrolyte plate, by preventing passage of fuel such as methanol, crossover of the fuel can be prevented. The proton conductor having a porosity of 5% or less is used to enhance conductivity.
