Abstract: PURPOSE:To enable to change the capacity of a room air conditioner freely to a desired level, by providing a structure of check valve in a stepped bore opened in a cylinder of a compressor, and connecting the stepped bore to a low-pressure section of a refrigerating cycle via a by-pass pipe having therein a stop valve. CONSTITUTION:With closing of a stop valve 22 during rated operation of a compressor, pressure in a space 33 defined between a valve plate 24 and the stop valve 22 becomes substantially equal to that PthetaH in a pressure chamber 9 at the time when a rolling piston 13 comes to a position of the setting angle thetaH of a stepped bore 19, so that the valve plate 24 is rendered immovable. Here, since the position thetaH where the stepped bore 19 is formed can be made greater that an angle thetad at which pressure is raised to the discharge pressure, the capacity of the compressor can be changed in a wide range. Further, since a spring 25 is inserted into a diameter-reduced bore section 26 of a stepped pipe 31 and stopped at a stepped portion 27 of the pipe 31 while using the top 28 of the stepped pipe 31 as a stopper for the valve plate 24 and a gas passage 30 is formed at a large-diameter portion 29 of the pipe 31, it is enabled to simplify the structure and to render the operation of valve plate 24 stable.

Filed: 1979-08-27
Abstract: PURPOSE: To provide a perpetually operating device without receiving power supply from other sources by allowing a part of device to push against other parts  while being pushed by other parts or to draw while being drawn.  
     CONSTITUTION: A part of device is designed to push against other parts of the device while being pushed or to draw while being drawn. For example, a genuine diamagnet 5 of supperconductor is provided in a super cryogenic chamber 8 which  rotates at the center of a rotary shaft 9 between counter-diamagnet fields 3 and 3'  produced by suppercurrent or persistent current. When the diamagnet 5 is magnetized as illustrated in FIG. A by the fields 3 and 3', they will repel each other  and rotate in the direction of arrow. While the magnetism of the diamagnet 5 is  maintained, they will be drawn by the fields 3 and 3' and turned to the state of  FIG. B. The polarity of the diamagnet 5 will be soon reversed by the diamagntism  and they will repel each other and return to the previous state of A. This is repeated endlessly so that they will rotate perpetually.

Title: Mold for casting
Inventor: HASE TAKEO
IPC: B29C39/40
Filed: 1985-05-20
Abstract: PURPOSE:To homogenize the hardening degree of a hardened product itself by a method wherein the heat absorption rate of surface of the mold for casting is increased locally to harden and contract the product sequentially from the deep side of the mold. CONSTITUTION:Blacked sections 6, blacked by coloring of dyes, coating of coating agent, formation of metal oxide or the like, are provided at sections, most far from the casting port 2 of casting mold of aluminum. The heat absorption rate of the rough surface of aluminum, being employed for the mold, is 0.06, however, the absorption rate may be improved to about 0.9 by blacking one part of the surface. Accordingly, the hardening of the product is progressed from sections, most far from the casting port 2 of thermosetting resin, and hardening and shrinkage are generated in such manner. In this case, the resin, whose amount is corresponding to the space of the shrinkage, is supplemented from the casting port 2. Further, the temperature of the whole of mold arrives at a given temperature after a predetermined time has elapsed, therefore, the hardening degree of the hardened product itself may be homogenized.

Title: Device for investigating form feature of sample surface
Inventor: FLECHA EDWIN
IPC: G01N37/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for improving the accuracy of measurements made by a scanning probe microscope. SOLUTION: A scanning probe microscope 10 has a probe 18 which moves as it is engaged with and separated from a sample surface by the combination of deflection generated in a high-speed actuator 22 having a relatively small range of motion and deflection generated in a low-speed actuator 26 having a relatively large range of motion. If the deflection of the high speed actuator moves out of a predetermined range, the low speed actuator operates in such a way that the next operation of the high speed actuator brings the high speed actuator back to the predetermined range. If the low speed actuator is required to be operated in this way, scanning movement whereby a sample surface is moved to pass through a probe is stopped until the probe is brought to the correct engagement level with the sample surface, so that the high speed actuator is deflected within the predetermined range.

Title: Junction type disc wheel of light alloy
Inventor: MATSUI HITOSHI
IPC: B60B3/06
Filed: 1982-06-26
Abstract: PURPOSE:To reduce the generation of crack on a rim side and consequently improve the durability of the disc wheel by a method wherein a surface treatment by shot peening is applied on the rim side of a weld bead, which is applied to the junction between the rim and a disc of the vehicular disc wheel. CONSTITUTION:Because the existence of a depression caused by the final end part or a part of boundary line of rim 1 side of weld bead 11 together with a corner 5 so as to form a notch 12 develops the possibility of the generation of cracks 13 in the vicinity of the notch 12, ring-shape shot-peening treatment is applied from a nozzle 15 along the peripheral surface onto a surface 14 near the boundary line of the rim side weld zone of the weld bead. Even if a notch 12 or an unhomogeneous part is generated by welding, the tensile stress generated at the rim 1 and the weld bead during the running for a long period of time can be relieved because of the residual compression stress developed at said rim 1 and weld bead 11 by shot-peening action.

Title: Optical recording method
Inventor: OGAWA IPPEI
IPC: G11B7/0055
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording method in which a low-linear-velocity recording operation and a high-linear-velocity recording operation can be performed more effectively to a phase change-type optical recording medium in which a multispeed recording operation can be performed. SOLUTION: In this optical recording method, at least a low-linear-velocity recording operation and a high-linear-velocity recording operation can be performed to a phase change-type optical recording medium in which a multispeed recording operation can be performed. The ratio Pel/Pwl of erasing power Pel to recording power Pwl in the low-linear-velocity recording (1x recording) operation of the phase change-type optical recording medium is set to be smaller than the ratio Peh/Pwh of erasing power Peh to recording power Pwh in the high-linear-velocity recording (2x/4x recording) operation. Thereby, residual heat in an erasing region is suppressed, and a proper mark can be recorded. As a result, a signal characteristic in the low-linear-velocity recording operation can be enhanced.
