Title: Variable displacement compressor
Inventor: HATSUTORI MITSUHIRO
IPC: F04B49/24
Filed: 1981-06-04
Abstract: PURPOSE:To simplify the structure of a variable displacement compressor, by using only  one on-off valve, and disposing the valve capable of enclosing a work chamber at an  intermediate part of a conduit which communicates the work chamber with an intake  system so as to pressurize fluid in the work chamber through thermal expansion of the  same that is caused by the temperature rise of a housing at the time of compression  cycle. CONSTITUTION:When the temperature in the cabin of a vehicle is raised due to shortage of cooling capacity by reason that the rate of operation is 50%, a capacity increasing instruction is given from a control unit for operating the apparatus at a rate of  100% by closing an on-off valve 55 and urging a discharge valve 41 onto a valve plate  4. Thus, according to the present invention, a passage 53 connected to a work chamber  52 is communicated with a conduit 54, and the on-off valve 55 is disposed at the intermediate part of the conduit 54, so that the discharge valve 41 can be moved between  its valve opening and closing positions through utilization of the on-off movement of  the valve 55 and the temperature rise of a housing 6 caused by compression of fluid.  Thus, since only one on-off valve 55 having no problem about sealing is used and electric codes for controlling the valve 55 can be arranged in a single system, it is enabled  to simplify the structure of the compressor.

Title: Oil pan structure for automobile
Inventor: KINDO MASAHIKO
IPC: F02F7/00
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To reduce the lower surface vibration of an oil pan so as to suppress sound radiation by holding an oil layer clearance in a manner that the near center of a bottom surface is relatively smaller than an inner pan peripheral part in an oil pan structure having a thin oil layer provided between an inner pan wall surface and an oil pan inner wall surface. SOLUTION: An inner pan 1 having a level difference 2 formed roughly in the center part of the shallow part 3 and sunk by its self weight holds a clearance to a minimum nearly in the center of a bottom surface. Thus, the bottom surface center becomes a body position for a low-order film mode, and when oil held between the oil pan and the inner pan 1 is moved at a flow velocity in a direction in parallel with the inner pan 1, oil shearing is produced and an attenuating force is applied in proportion to this, oil viscosity and an area. The rigidity of the level difference 2 is improved, an inner pan peripheral end part clearance nearly equal to the side wall clearance is obtained and thus supplying of oil to the bottom surface is facilitated.

Abstract: PURPOSE: To prevent the purification of Na from being interrupted in a liq. Na purifying apparatus using a β-Al 2 O 3  partition wall by electrically insulating the unpurified Na container and/or the purified Na container from the duct for carrying unpurified Na.  
     CONSTITUTION: Unpurified na container 1 and purified Na container 2 are placed at both sides of β-Al 2 O 3  partition wall 3, and by applying a DC voltage to anode 5 and cathode 6 in containers 1, 2 from power source 4, pure Na is passed through wall 3 from the anode side to the cathode side to purify unpurified Na. At this time, the upper wall of container 1 is set at a position higher than that of container 2 and unpurified Na injecting pipe 10 is attached to the upper wall of container 1 with insulating member 9 in-between. Empty duct 7 for unpurified Na is connected to pipe 10 through on-off valve 11. Valve 11 is controlled with control circuit 12 which ddtects an electric current flowing between anode 5 and cathode 6 and opens or closes valve 11. When the surface of Na in container 1 lowers and separates from anode 5, the current is interrupted, valve 11 is opened with circuit 12 to supply unpurified Na from pipe 7, and purification is continued.

Title: Disk position detector
Inventor: SAWABE YOSHIKATSU
IPC: G11B19/10
Filed: 1988-04-08
Abstract: PURPOSE:To prevent the damage of a disk or malfunction from being generated by judging whether a second magnetic disk is exactly positioned and mounted or not according to signals from plural detectors which are arranged along the edge of a second guide part. CONSTITUTION:The rays of light to be projected from photo-interrupters 18-20 through through holes 15-17 are abutted to a second disk 22, which is exactly positioned and placed to a second guide part, and reflected. Then, the rays of light are received again through the through holes 15-17 to the photo- interrupters 18-20 and the signal of an H level is generated. When a second disk 22 is not exactly positioned and placed, the projecting light is not received by the photo-interrupter 18, for example, and at such a time, the signal of an L level is generated. Thus, only when the signal of the H level is outputted from all the photo-interrupters 18-20, the output of a NAND circuit 21 goes to the L level and it can be detected that a second disk 22 is exactly positioned and mounted to the second guide part.

Title: Control valve
Inventor: TAKESHIMA KIKUO
IPC: F16K1/06
Filed: 1986-04-15
Abstract: PURPOSE:To reduce the extent of seat ring erosion due to a valve seat leak, by installing a baffle in a valve box at the downstream side. CONSTITUTION:A circular baffle 7, narrowing an outlet passage and keeping pressure inside, is installed inside at the downstream side of a valve box 1 as hung down from the valve box ceiling. The baffle 7 is formed simultaneously by a casting mold at time of producing the valve box. A fluid flowing in from the valve inlet side passes through the narrow valve seat part formed with a cage 2 and a valve body 5. Here, since there is the baffle 7, pressure in a space of a valve outlet part goes up as compared with the conventional case, becoming more than saturated steam pressure. In consequence, a flow velocity at the valve seat outlet is sharply dropped, so that erosion in a seat ring and damage to a bottom part of the valve box come to be brought to nothing there.
