Title: Refrigerator
Inventor: KAMISAKO TOYOSHI
IPC: F25D11/00
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To dissolve a problem that there is no method to confirm humidity of a refrigerating chamber by a user for a refrigerator since humidity is non- visible though the increase of humidity in a conventional refrigerating chamber is practicable. SOLUTION: A dry and wet display sheet 10 containing a pigment the color of which is changed according to a change of humidity is situated at the whole or a part of a refrigerating chamber shelf 4 of a refrigerating chamber 3 or at an inner box 2 of the refrigerating chamber. This constitution causes a user to simply recognize humidity in the refrigerating chamber by changing the color of the dry and wet display sheet 10 according to a change of humidity in the refrigerating chamber.

Title: Electrostatic recorder
Inventor: SHIMIZU SHIGERU
IPC: G03G15/05
Filed: 1989-10-27
Abstract: PURPOSE:To stably obtain a high-resolution image without wearing out a recording head by driving a controlled electrode at a low voltage and controlling it according to recorded information while a high-pulse voltage of a fixed cycle is applied to the part facing an electrode. CONSTITUTION:A developing roll 4 is rotatably provided on the upper inside of a toner carrier 5. The roll 4 firmly fixes a magnet roll 4b to a cylindrical screw pole 4a where a linear electrode is spirally placed on the peripheral face. A cylindrical electrode 6 is oppositely disposed at a prescribed distance away from the pole 4a via the film 5a of the carrier 5. While a fixed cycle pulse power source 10 applies a pulse voltage in a fixed cycle so that the phase of the linear electrode becomes identical to that of a voltage applied to the controlled electrode 8 at the time of recording, the electrode 6 and the roll 4 are rotated, and a recording pulse power source 9 applies a pulse voltage corresponding to the recorded information to the electrode 8 only at the time of recording. Ultimately, a toner recorded image corresponding to the recorded information is formed on paper fed from a standby roll 2 and the electrode 6. Thus, a satisfactory image is stably recorded and formed on plain paper.

Filed: 1992-09-29
Abstract: PURPOSE:To perform electric resistance welding which is being excellent in corrosion resistant effect and welding strength by melting only an aluminum- coated layer by primary energizing to allow steel wires to come into contact with each other and then, performing welding by secondary energizing. CONSTITUTION:The aluminum-coated steel wires 1 and 2 are crossed each other to perform electric resistance welding. At that time, only the aluminum- coated layer of a crossed contact part is melted by primary energizing to allow the steel wires 1 and 2 to come into contact with each other and then, the welding is performed by secondary energizing. In primary energizing, an applied electric current is increased and the energizing time is shortened and in secondary energizing, the applied electric current is decreased and the energizing time is extended. The welding is performed under conditions of a welding work stroke H of 3-6mm, the pressurizing force of 1-5kg/cm, the primary energizing time of 5-30 cycles (electric power frequency), the primary applied current of 3000-150000 (A), the secondary energizing time of 10-60 cycles (electric power frequency) and the secondary applied current of 1000-5000 (A). Consequently, a smooth welded body without producing burrs can be obtained.

Title: Oil seal
Inventor: OBATA HIROMI
IPC: F16J15/3232
Filed: 1990-10-19
Abstract: PURPOSE:To enhance the sealing function by furnishing a plurality of ring grooves at that surface of a seal lip of No.2 seal element made of synthetic resin which comes in contact with the surface of a rotary shaft, and encapsulating a fluid in this No.2 seal element through the action of these grooves. CONSTITUTION:No.1 seal element 1 is made of rubber and equipped with a seal lip 2, while No.2 seal element 4 is made of synthetic resin and equipped with a seal lip 5 extending along the back surface of the first named seal lip 2, and these two seal elements are installed in single piece structure. At that surface of the seal lip 5 which comes in contact with the surface of a rotary shaft, a plurality of ring grooves 7 are formed in the circumferential direction of the rotary shaft. Because the area between grooves contacting the surface of the rotary shaft lessens if the inter-groove width is lessened. a large surface pressure due to contacting is obtained in the region between grooves even though the seal lip 5 deforms so that it is in plane contact with the surface of the rotary shaft. This surface pressure obtained seals fluid completely, so that eventually leaked liquid from the seal part 3 of No.1 seal element 1 can be sealed certainly with the No.2 seal element 4.

IPC: G03G15/20
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain a fixing roll which has equal performance to that of a soft roll with a simple structure and can be used for rapid fixing by constituting the roll of a mandrel, a specified adhesive layer and a specified release resin layer. SOLUTION: The fixing roll 1 has a two-layer structure and is reduced by applying a Si-based adhesive 4 in a layer state on the surface of a mandrel 5 and then covering the mandrel with a fluorocarbon resin nonshrinkable tube 3. The Si-based adhesive 4 has flexibility to allow the coating film on the roll to follow up the roughness state of a coarse paper. In this case, by applying the Si-based adhesive 4 to the thickness between 50μm and 170μm, good heat conduction to the roll surface can be obtd. during continuous printing while the flexibility of the roll is not decreased. Thus, decrease in the roll temp. is reduced and good fixing property is obtd.  By using a fluorocarbon resin nonshrinkable tube 3, for example, a tube having thickness between 30μm and 50μm, the production of a tube-coated fixing roll having a large diameter as >60mm is made possible and a release resin layer having a high heat conducting effect and high coating film strength can be obtd.
