Title: Refrigerating cycle
Inventor: MATSUMURA KENJI
IPC: F25B13/00
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To improve an operating efficiency of a refrigerating cycle by providing an opening communicating with a gas refrigerant of an upper portion of a liquid receiver through an upper portion of an introducing/discharging tube connected to a user side heat exchanger in the receiver and providing a circuit for by-passing the gas refrigerant from the upper portion of the receiver to the tube of the receiver. SOLUTION: A two-phase state refrigerant decompressed by an electronic expansion valve 4 flows from an introducing tube 5-1 to a liquid receiver 5, and flows out from a discharging tube 5-2. In this case, the two-phase refrigerant flowing from the tube 5-1 to the receiver 5 is gas-liquid separated in the receiver, a gas refrigerant flows out from an opening 5-3 provided at an upper portion of the tube 5-2 to the receiver 5, and a liquid side connecting tube 9 becomes the two-phase state. The gas refrigerant of the upper portion of the receiver is taken out by a bypass pipe 6, and hence a refrigerant dryness of an outlet of the receiver becomes large, that is, a gas refrigerant ratio of the refrigerant flowing out from the receiver 5 becomes large.  Thus, the liquid refrigerant is forcibly stored in the receiver 5 due to a balance between inflowing liquid refrigerant to and outflowing liquid refrigerant from the receiver 5.

Title: Image recorder and electronic camera
Inventor: IKEDA OSAMU
IPC: H04N5/225
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To securely and efficiently utilize a recording medium and power without burdening an operator by providing a control means stopping the recording operation of moving picture information by means of a recording means when a detection means detects image information satisfying a predetermined condition. SOLUTION: The detection means 14 detects the image information satisfying the predetermined condition from the image information which is taken in by an image input means 10. The control means 16 stops the recording operation of the moving picture information by the recording means 12 when the image information satisfying the predetermined condition is detected by the detection means 14. Thus, the recording operation can automatically be stopped when the image information satisfying the predetermined condition is taken in a state where the recording operation of moving picture information is executed. Thus, the recording medium and power can efficiently be used without executing the unnecessary recording operation.

Title: Picture processing method
Inventor: YAMAGUCHI YASUHIKO
IPC: H04N1/40
Filed: 1988-05-25
Abstract: PURPOSE:To decide an optimum threshold level to an original by deciding the threshold level for multi-value processing in response to the minimum density, maximum density of a picture data and the shape of a density histogram. CONSTITUTION:The frequency of a background part (part of low density, i.e., thin part) is high in a conventional character original, the f of a character part (high density, i. e., dark part) is low and then the background part is dominant as a whole. Then the maximum density WH is not used, and the minimum density WL, the maximum frequency KP of a character part and its density WP are used to decide the threshold level TH by the data. For example, when the maximum density KP is large as shown in figure (a), the difference of threshold levels is decreased, and when the density KP is small as shown in figure (c), the difference is widened conversely, and in an intermediate case as shown in figure (b), the proper level is used. Thus, the threshold level suitable for the character part is set.

Title: Watch
Inventor: SATOU KATSUHIKO
IPC: G01D13/22
Filed: 1978-10-12
Abstract: PURPOSE: To realize an ultra-thin structure for the wristwatch along with the steady movement of the watch hands by using the electret elements at and around the hands.  
     CONSTITUTION: Electret element 6 featuring the electric charge polarized in the thickness direction is formed into the transparent film type to be adhered on the inner surface of glass 7. Also transparent disk-type electret elements 10 and 11 on which the shapes of the minute and hour hands are printed plus electret element 12 provided on movement 9 undergo the polarization process in the thickness direction as well. When the polarities of the surface charge are arranged into the same polarity among these elecret elements mentioned above, the repulsive power is produced. Using this repulsive power, the minute and hour hands comprising elements 10 and 11 are made to stand still in the gap between glass 7 and movement 9, thus always securing the normal movement of both hands. In this way, both the thickness of the hands and the gap where the hands are stored can be decreased, thus reducing greatly the thickness of the wristwatch.

Title: Getter component for light source
Inventor: FUERENKU NAAGERU
IPC: H01J7/18
Filed: 1990-05-16
Abstract: PURPOSE: To prevent generation of harmful materials and to improve getter performance by using a volatile solvent for a carrying material, and by using zirconium alloy as a metallic component. CONSTITUTION: A getter comprises 15 to 35wt% powdered nickel, 30 to 70wt% zirconium alloy, and the remainder thereof formed of aluminum having a thin- layer structure carrier by a carrying material. In this case, the carrying material is formed by using 20 to 80vol% volatile solvent, and does not contain connective components. Hence there is no generation of harmful material due to dissolution of the connective components. A nickel powder promotes sintering, and the guttering effect of zirconium alloy is improved. Compared with the case of using zirconium individually, the zirconium alloy enhances hydrogen coagulation hardening capability and facilitates pulverization with effective getter formation.
