IPC: F25B29/00
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To eliminate a check valve of a piping for recovering a liquid refrigerant to a subtank in a refrigerating device having the subtank for recovering a part of the liquid refrigerant extruded from a main tank and supplying it to a heating heat exchanger for generating high pressure by exerting high pressure and low pressure on the main tank in which the liquid refrigerant is stored, extruding the liquid refrigerant from the main tank and recovering the liquid refrigerant to the main tank under these pressures so as to convey heat by the refrigerant. SOLUTION: The downstream end of a piping 37c for introducing a part of a liquid refrigerant extruded from main tanks T1 and T2 to a subtank ST is opened to a gas area in the upper part of the subtank ST. In this structure, when the liquid refrigerant is extruded to a heating heat exchanger HEX3 from the subtank ST, the liquid refrigerant does not enter the piping 37c. Accordingly, it is not necessary to provide a check valve in this piping 37c.

Title: Dissolving solution for nickel-zinc alloy plating
Inventor: OISHI TSUTOMU
IPC: C23F1/30
Filed: 1987-08-27
Abstract: PURPOSE:To dissolve only the Ni-Zn alloy plating layer applied on a steel sheet with the title soln. by composing the soln. out of the essential components of nitric acid and hydrogen peroxide, a small amt. of chelate compd., and water. CONSTITUTION:The dissolving soln. is composed, by weight, of 5-15% aq. H2O2 soln., 5-15% nitric acid, 0.5-1% of the nitrilotriacetic acid (NTA) or ethylenediaminetetraacetic acid (EDTA) as the chelate compd., and the balance water. In the dissolving soln., H2O2 is easily decomposed into oxygen and water, and a passive coating film (F) can be formed on the iron surface by the generated nascent oxygen. Since the coating film (F) is not broken by nitric acid, the iron is exposed after the Ni-Zn alloy is eluted, the coating film (F) is immediately formed by the action of H2O2, and the elution of iron is prevented. Since the coating film (F) is not sufficiently formed when the dissolution reaction temp. of the Ni-Zn alloy is excessively increased, the chelate compd. is used as the reaction inhibitor to prevent such a phenomenon.

Title: Detector for ignition failure of internal combustion engine
Inventor: YOSHIMURA KEIJI
IPC: F02B77/08
Filed: 1981-12-28
Abstract: PURPOSE:To detect the ignition failure of each cylinder of internal combustion engine,  by detecting an oxygen concentration signal from an oxygen sensor mounted to an  exhaust pipe. CONSTITUTION:An output terminal of a lead wire 9 of an oxygen sensor 1 is connected  to an input terminal 14 of an ignition failure detecting circuit 10. The ignition failure  detecting circuit 10 is provided with an integration amplifying circuit 11 for inputting  an oxygen concentration signal from an oxygen sensor, a comparator 12 for comparing  the output signal of the integration amplifying circuit 11 with a reference voltage signal  previously set, and a monitor lamp 13 for an ignition failure to an operator when the comparing signal is a high level. It is acertained that the oxygen sensor 1 is brought  into higher than a given temperature after starting an engine, and an opening degree  of a throttle is controlled so that the number of revolutions of an engine attains a given value. In the case of, for example, 6-cylinder type internal combustion engine, if  each cylinder is ignited, the voltage signal of the oxygensensor generates an output  waveform shown in (A), and if an ignition failure occurs to some cylinder, it generates  a cone-shaped waveform (B) at a constant timing, which results in easily finding an  ignition error.

Title: Coordinate input device
Inventor: TAKAHASHI HIROMICHI
IPC: G06F3/046
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To enable distinguishable recognition between a pen pressure and an input of a pen signal or an operator's finger pressure by distinguishably recognizing signals while switching the case of the operator using a signal pen and the case of using the operator's own finger for the coordinate detection. SOLUTION: When the operator uses a signal pen 2, an AC signal is transmitted from an AC signal generator 5 built in the signal pen through an analog switch 9 to a band pass filter 13. At such a time point, a control part 15 stops impressing a DC signal to an electrode terminal 17 in the X-axis direction of a tablet 1. When the operator uses the signal pen 2, the AC signal is inputted to the band pass filter 13 since the signal pen 2 has the AC signal generator 5. Therefore, it can be recognized whether the signal pen 2 is used or not, the signal is rectified by a rectifier part 14 and outputted to the control part 15 later, and it can be recognized whether the operator uses the signal pen 2 or uses an operator's finger 4 for inputting.
