Patent JP-H0571828-A (JP)
Title: Freezing device
Inventor: NUMAZAWA SHIGEO
IPC: F25B39/02
Filed: 1991-09-11
Abstract: PURPOSE:To provide a freezing device which reduces incurring of the pressure loss of a refrigerant when an amount of a refrigerant flowing through the refrigerant channel of a vaporizer is high and returns a refrigerant to a compressor without gathering quantities of lubricating oil in a vaporizer when an amount of a refrigerant flowing through a refrigerant channel is low. CONSTITUTION:A second partition plate 12 is arranged in a second refrigerant channel 10 and the second refrigerant channel 10 is divided into first and second split channels 10a and 10b. Since when an amount of a refrigerant flowing through a tube 4 is high like a summer season, a refrigerant flows through both the first and second split channels 10a and 10b after the flow of it through a first refrigerant channel part 8 and a communicating part 9, a current pressure loss is reduced. Meanwhile, when an amount of refrigerant flowing through the tube 4 is low like a winter season, lubricating oil contained in the refrigerant is gathered in the communicating part 9. Lubricating oil is brought into a state to close the first split channel 10a and as a result, the velocity of flow of the second split channel 10b is increased. Lubricating oil flows over the high velocity of flow and up to a header 3b.

IPC: C10N10/08
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition capable of maintaining low contact resistance in use at high temperatures even in a contact of a small current by adding a titanate-based and an aluminum-based coupling agents thereto. SOLUTION: This grease composition contains at least one additive selected from a titanate-based coupling agent and an aluminum-based coupling agent capable of preventing a film from forming due to the oxidation of a copper surface. For example, the titanate-based coupling agent is represented by the formula (R<1> O)n -Ti-(OR<2> )4-n [R<1> is a 1-10C alkyl or a 1-10C alkoxy; R<2> is a 1-20C acyl; (n) is 1-4] or the like and an acetoalkoxyaluminum diisopropylate is cited as the aluminum-based coupling agent. The coupling agent in an amount of 0.05-5 wt.% in the grease composition is added thereto. Thereby, the oxidation and corrosion on the surface of a copper contact can be prevented and the grease composition is especially effective in lubricating a sliding electrical contact.

Title: Constant current source circuit
Inventor: NANBU HIROAKI
IPC: G05F3/16
Filed: 1988-09-19
Abstract: PURPOSE:To reduce the temperature dependence properties of the voltage Vs by specifying the relation between both currents JAi and JBj flowing to the pn junction for generation of the forward/reverse bias voltage in order to produce the voltage Vs via a level shift circuit. CONSTITUTION:In a level shift circuit, the currents JAi and JBj are supplied to L and M pieces of pn junction for generation of the forward and adverse bias voltages VAi and VBj. Thus the voltage Vs is produced and applied to a 1st load with the load current applied to a 2nd load respectively. Under such conditions, a constant current circuit is obtained. Then both currents JAi and JBj are connected to each other via the specific formulas (I - III). In this case, ES means an energy gap of a semiconductor together with the Boltzmann constant (k), the electronic charge (q), the gradient coefficient (n) of the junction voltage/current, and the working temperature T. Then ai and bj mean the positive real numbers to satisfy ai>k>0 (k=SIGMAai-SIGMAbj). Here the partial differentiation is applied to the voltage Vs via the temperature T, and the relative formula between the currents JAi and JBj is used. Thus the partial differention value is approximately equal to zero. Otherwise the JAi and JBj are connected to each other with another specific relation and the B value of '-kA+B' is selected. As a result, the temperature dependence properties of the Vs can be optionally set.

Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the relieving efficiency of defective bit lines by selecting redundant memory cells in a selection unit smaller than that of normal memory cells and relieving the defective section of a normal memory cell part by replacing the section by a redundant memory cell. SOLUTION: When a defective column is present in a normal column which shares a regular data line DQ1 and a defective column is present in a normal column which shares a regular data line DQ3, a fuse logic circuit writes the address so that the column address inputs of normal data lines of the normal data lines DQ1, DQ3 are respectively converted to the column addresses of the redundant data lines RDQ3, RDQ4. By this, a redundant memory cell substitution control circuit selects the normal column selection transistor RCQ of the redundant bit line RBL connected to the redundant data line RDQ3 to replace the normal data line DQ1 by the redundant data line RDQ3. Similarly the normal data line DQ3 is replaced by the redundant data line DQ4. Thus relief is performed in the unit of data line.
