IPC: F02B75/02
Filed: 1992-10-23
Abstract: PURPOSE:To minify variation of a lubricating oil feed quantity by mounting a capillary tube between a lubricating oil feed device and a lubricating oil discharge passage, and forcedly heating the capillary tube or a part of a lubricating oil feed duct by an engine cooling discharge air. CONSTITUTION:A duct 12 is connected to an oil tank 10 and an oil pump 11. The duct 12 is connected to a suction port 13. A duct 15 is connected to a discharge port 14 and a capillary tube 18. A duct 17 is connected to the capillary tube 18 and an intake port 7. Discharge air 19 is an engine cooling air after cooling the engine and flows outside of the capillary tube 18. The capillary tube 18 exhibits an appropriate restriction effect by the length and the bore so as to adjust a lubricating oil quantity. Further, it is heated by the discharge air 19, the temperature of lubricating oil becomes higher than the environment temperature, and hence variation of lubricating oil viscosity due to variation of temperature is made minimum. In this way, variation of the lubricating oil feed quantity is minified against variation of the environment temperature.

Title: Electronic component mounting machine
Inventor: TANAKA SHIGEKI
IPC: H05K13/02
Filed: 1990-11-16
Abstract: PURPOSE:To extend a usable period of a suction nozzle by sucking a component by the nozzle from the position of a tape when a tape is intermittently fed by tape feeding times designated at each tape. CONSTITUTION:Tape feeding times of intermittently feeding a tape to suction of an electronic component are preset at each tape number. For example, if the times is once, when the tape is fed intermittently once, a suction operation is started. Thus, after the times are set at each tape, an automatic operation program of an electronic component mounting machine is started, a tape feeder 5 then intermittently feeds the tape 1 at a predetermined interval by the times set according to the tape 1, and a component suction robot 3 starts to suck the component. Thus, since the component 2 is disposed directly under a suction nozzle 3 when the tape 1 is fed, the suction of the component is ended by one suction to reduce the number of using of the nozzle 3 is reduced, and friction can be reduced.

Title: Reel driving mechanism for magnetic recorder/ reproducer
Inventor: MAEDA OSAMU
IPC: G11B15/26
Filed: 1990-11-15
Abstract: PURPOSE:To achieve higher reliability by performing a winding at a large torque not through a slipping mechanism when a tape hub rotation load is large during an unloading. CONSTITUTION:Signals from both reel rotation sensors 2 and 3 are inputted beforehand and it is judged whether a reel is at rest or not in a mode of unwinding, quickly feeding a tape or the like to store whether a rotation load of a hub of a cassette is large or not into a microcomputer 1. When the reel stops during the operation of quick feeding, unwinding or the like, the rotation load of the tape hub may be too large to wind the tape when the the winding is done through a slipping mechanism. So, a winding torque is upgraded with a microcomputer 1 thereby preventing a trouble such as leaving a tape end.

Abstract: PURPOSE:To reduce the temperature change of a wafer during conveyance by constituting a conveyance mechanism, which conveys a substrate to be processed, such that the margin of the substrate to be processed is held at plural points by plural claws for holding the substrate. CONSTITUTION:A ring-shaped supporting frame 52 is provided at the end of the arm 51 of a wafer holding part 50. And three pieces of claw-shaped supporting members 60 are attached approximately at equal intervals so that the supporting parts 62 at the ends may be projected toward the inside of the supporting frame 52. Taper edges 64 are formed on the tops of these supporting parts. These taper edges 64 are sloped downward as they go to the tops. And a wafer W is supported at three points by the taper edges of the supporting parts 62, so the area of the contact part between the wafer W and the supporting member 60 becomes extremely small. For this reason, even in the case where the temperature difference between the wafer W and the supporting member 5 is as high as 70-80 deg.C such as after baking treatment, the temperature change of the wafer W before and after the holding can be suppressed to the range of + or -0.3 deg.C.

Filed: 1987-12-11
Abstract: PURPOSE:To part values of both counters with each other even with any value of both the counters by comparing all output bits of a write counter and a readout counter and inverting the most significant bit of the write counter when they are coincident. CONSTITUTION:When each output bit (4 bits) of the write counter 2 and the readout counter 4 is coincident with each other, a comparator 6 outputs a low level signal and when dissident, the comparator outputs a high level signal. Thus, when the count of counters 2, 4 is 0010, for example, since a low level signal is outputted from the comparator 6, 1010 is loaded to the counter 2 synchronously with the leading edge of a clock 1. As a result, a difference of the counts of both the counters 2, 4 is 7 to attain stable write/read at all times.
