IPC: F16H55/28
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To transmit pre-load to a steering rack by storing a rack guide between a lid cap and a rack and further installing a spring in a space up to the lid cap in compressed state in a housing in a rack-pinion type steering device. SOLUTION: A rack guide 30 is stored between a lid cap 34 and a rack 14 provided in a cylindrical section 32 of a housing 12. Further, a spring 36 is installed in the compressed state between the rack guide 30 and the lid cap 34.

Abstract: PURPOSE:To enable thermal radiation of a heat exchanger to be carried out without using any fan irrespective of a natural air flow by a method wherein a duct is mounted on an upper part of a condensing heat exchanger, an upper part of the condensing heat exchanger is expanded more than its lower part and a compressor is stored in the heat exchanger. CONSTITUTION:A compressor 1 is mounted in a part enclosed by a condensing heat exchanger 2 and the heat exchanger 2 is disposed in such a shape as one in which it is expanded from its lower part toward its upper part. Air in an outdoor unit is heated by a radiation of condensing latent heat for cooling of the heat exchanger 2 and a heat radiation of the compressor 1 so as to generate a buoyancy. Air around the heat exchanger 2 is fed inside the outdoor unit under a natural convection flow as indicated by a broken arrow due to a draft effect in a duct 10 and then the air is discharged out of the upper part of the duct. Accordingly, it is possible to promote heat radiation of the heat exchanger 2 against the surrounding air without using any fan. Since the heat exchanger 2 is disposed over the ground earth 12 by an installing table 11, it is also possible to perform heat radiation of the forced convection flow to the surrounding air with natural air.

If the terminal having the same coordinate value of the pin b5 is not detected, a package substrate terminal having the coordinate value closest to the Y axis coordinate value of the extracted pin b5 is selected. Then a package substrate terminal having the minimum Manhattan distance from the pin b5 is allocated to the relevant parts pin within a range including upper and lower (p) pieces of terminals centering on the selected package substrate terminal (p equal to 1 in this example). The wiring between those allocated package substrate terminal and parts pin is set so that it does not cross another completed wiring.
