Title: Sterilizing device for drink supplier
Inventor: SAKAI KIYOSHI
IPC: G07F13/00
Filed: 1988-07-18
Abstract: PURPOSE:To enable sterilization of a part of pipe lines exposed to atmospheric air of a drink supplier by impressing DC to a pair of electrodes disposed to a pipe at an outlet side of a drink feed valve exposed to atmospheric air, electrolyzing the drink stagnating in the pipe line, and transforming chloride ions to chlorine molecules. CONSTITUTION:Two pairs of electrodes 26a, 26b and 27a, 27b are disposed to a passage of carbonated water 23, which is as a pipe line for feeding drink at an outlet side of a drink feed valve 3 exposed to atmospheric air. Chloride ions contained in the carbonated water are transformed to chlorine molecules when DC is impressed to the electrodes. The chlorine molecules generate hypochlorous acid having sterilizing effect when it is dissolved in water. Thus, the passage 23 of the carbonated water is sterilized. By this constitution, sterilization of parts in the pipelines for feeding drink where proliferation of bacteria occurs easily because of exposure to atmospheric air of the parts is executed by a simple operation, preventing thus invasion of bacteria into inside of a drink feed valve.

Title: Structure for silencing screw compressor
Inventor: UTSUNO HIDEO
IPC: F04C29/12
Filed: 1990-07-05
Abstract: PURPOSE:To greatly reduce pressure pulsation so as to reduce the noise of a device and also miniaturize a silencing structure itself by filling the overall cross section of any of the portions of a discharge pipe with oil, the discharge pipe being connected to the discharge opening of a compressor main body. CONSTITUTION:In an oil cooled type screw compressor a discharge pipe 13 connected to the discharge opening 12 of a compressor main body 11 is connected at its end opposite the discharge opening to an oil separation recovery unit 14 at a position below the oil surface of the oil collecting portion 15 of the oil separation recovery unit 14 and the overall cross section of the end portion is filled with oil whereby the end portion serves as a silencing structure 1. When gas discharged from the discharge opening 12 is allowed to enter the oil collecting portion 15, approximately the total reflection of pressure pulsation of the gas is caused by the difference in density between the gas and the oil and pressure pulsation passing through the oil collecting portion 15 is weakened and thereby pressure pulsation in an air storage portion 20 is weakened, reducing noise that leaks outside of the compressor. The oil separation recovery unit 14 utilizes the space above the oil surface as the air storage portion 20 and has an oil separation recovery element 22 attached to the inlet side of the outlet portion 21 thereof.

Abstract: PROBLEM TO BE SOLVED: To reproduce contents having a reproducing frequency limit. SOLUTION: An audio data file having a reproducing frequency limit is reproduced from a memory card 40 to be decoded by an audio decoder 12 and to be reproduced. A lapse time of a reproduction time for the file is counted based on a data amount transferred from a DSP 30 to the audio decoder 12. When the lapse time exceeds a prescribed time, the number of reproduction times is determined to be counted as one reproduction, and a value of a reproduction frequency CT is brought into decrement. When the requency CT reaches to zero, a reproduction operation for the audio file is prohibited on and after it. When an instruction except a usual reproduction operation is issued midway of the reproduction, the counting of the lapse time is stopped temporarily, or the counted lapse time is reset.

Abstract: PURPOSE:To make its structure simple to prevent crosstalk and to remove an isolation region to make this device small-scaled, by disposing a plurality of photodetectors in the form of an array on a semiconductor substrate so as to form a light-receiving part and next by applying a magnetic field, which has a component perpendicular to a surface of the semiconductor substrate, to the light-receiving part. CONSTITUTION:An infrared-ray detector 45 is provided with a light-receiving part 34, where a light signal is converted into an electrical signal, and a signal-drawing part 40. A plurality of small-scaled semiconductor layers 32 are disposed in the form of an array on a substrate 31 by an impurity doping method. A Pn junction 33 composes a photodetector. A signal drawing part 40 is formed of an Si substrate 35, a source 36 composing a transfer gate, a drain 37, a gate 38, and a CCD 39. The photodetector at the light-receiving part 34 is connected with the transfer gate at the signal-drawing part 40 by the use of a bump electrode 41. A coil 43 for use in applying a magnetic field 25 is made adjustable in its strength. When the magnetic field 25 is applied to the light-receiving part 34, motion of carriers is limited and so cross talk can be prevented from occurring. Carriers generated between adjacent photodetectors can be made to attain to pn junction parts of both the photodetectors, and an insensitive region can be removed, so that performance of this device can be improved.
