IPC: B60T1/06
Filed: 1991-12-18
Abstract: PURPOSE:To moderate heat conduction to a driving shaft and perform the design and manufacture of a disc brake device and a drive unit separately so as to improve production efficiency by providing a cylindrical spline shaft to be force-fitted to the end part of the driving shaft, leaving a hollow part inside a spline with a rotor fitted to its outside. CONSTITUTION:The tip part of a driving shaft 15 is fitted into a spline shaft 16, and a spline 17 is formed at the outer periphery of the spline shaft 16. The driving shaft end in the spline shaft 16 is formed into a hollow part 18, and a rotor 8 is provided slidably to the spline 17. The hollow spline shaft 16 with the spline 17 formed at the outer periphery is force-fitted, at its hollow part, to the tip of the driving shaft 15 protruding to a disc brake device body 2 from a drive unit body 1 so as to be rotated together with the driving shaft 15 and prevented from sliding even by torque at the braking time. The hollow part 18 at the tip of the spline shaft 15 is secured as the forcefitting margin of the driving shaft 15. The demarcation between the driving shaft 15 and the spline shaft 16 can be thus clarified.

Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent the fluctuation of burning condition due to the fluctuation in time of adhering amount of water drops (drain), adhered to a latent heat recovering heat exchanger due to the phenomenon of vapor condensation. SOLUTION: An air volume sensor 27, detecting the air volume of a fan due to the driving of a combustion fan 10, is provided. The data of relation between the air volume of fan to supply air for effecting complete combustion to a burner 3 and the heat amount of combustion is given and an objective air volume, compatible to a required amount of heat of combustion, is detected based on the data of relation while the combustion fan 10 is driven so that the air volume, detected by the air volume sensor 27, becomes the objective air volume. An exhaust resistance is fluctuated due to the fluctuation of the amount of drain, however, the optimum air for effecting complete combustion can be supplied surely by the air volume control of the fan whereby complete combustion condition can be continued stably.

Title: Wiring board
Inventor: NAKAGAWA SHOICHI
IPC: H05K3/46
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To relieve concentration of a thermal stress on a corner part by a method wherein a thermal transmission layer contains ceramics of specific wt.% and curvature at the corner part of the transmission layer is specified. SOLUTION: A recess rectangular in a plan shape having specific curvature 5 at a corner part 4 is formed in a specific area of a second layer from a surface layer of an insulating layer 2 of a three-layer structure. The curvature 5 has an option value within a range of 1/10 to 1/2 times the length of a rectangular short side. A mixture excellent in thermal conduction property and composed of high melting point metal and ceramics is filled in this recess part and integrally sintered to form a thermal transmission layer 3. The thermal transmission layer 3 contains ceramics of 5 to 20wt.% (10 to 15wt.%, preferably). When the curvature 5 is 1/10 times or less the length of a short side of the thermal transmission layer, cracks are developed and resistivity is changed. When exceeding 1/2, cracks generate in a wire board.  It is possible to relieve concentration of a thermal stress developed due to a difference of a coefficient of thermal expansion in both the thermal transmission and wire board on the vicinity of the corner part of the thermal transmission layer.
