Title: Built-up cam shaft with induction-hardened cam and induction-hardening method of cam
Inventor: GUSUTAFU HAANITSUSHIYU
IPC: F01L1/04
Filed: 1995-06-08
Abstract: PURPOSE: To elongate the life of a camshaft or a cam disc by inductively hardening a surface layer on an outer periphery of a cam disc on a camshaft by the alternating magnetic field, and increasing the internal compression stress produced on the hardened surface zone by the hardening. CONSTITUTION: This camshaft 1 comprises an approximately annular cam disc 3 fixed on a tubular shaft body 2. Relative to this cam disc 3, the surface layer hardening is executed by the induction of an outer periphery, before its fixing. The hardening produces high internal compression stress of at least -450 N/mm<2> on a surface zone of about 0.5 mm depth near the surface. Whereby the internal tensile stress of at least -150 N/mm<2> exists even after the cam disc 3 is mounted on the shaft body 2. After the hardening, the cam disc 3 is preheated at least at 250 deg.C (but below transformation temperature) by applying a medium-frequency magnetic field to the cam disc 3, then the alternating magnetic field of different intensity or frequency is applied, and only the surface zone is heated by the transformation temperature, and then quenched.

Abstract: PURPOSE:To reduce the fuel consumption in low or middle load operation range by allowing an intake passage of the downstream of a throttle valve operated by an accelerating pedal to be branched into the primary side and the secondary side intake passages and installing a subthrottle valve whose opening degree is controlled according to the engine loaded state, in the secondary side intake passage. CONSTITUTION:In idling operation in which a throttle valve 6 is set into nearly complete closed state, a high intake negative pressure is introduced into each negative- pressure chamber 12d, 12e of a diaphragm apparatus 12 through negative-pressure conduits 13 and 14. Therefore, a subthrottle valve 10 is closed perfectly through an operating rod 15 and a lever 16through the upward movement of both diaphragms 12b and 12c. Therefore, the mixed gas is drawn in a primary-side intake passage 1a having a small passage area and flows into a combustion chamber 2 with a high flow rate when an intake valve 17 is opened, and a swirl flow is formed. When the throttle valve 6 is opened and transfer to low or middle load operation is performed, introduction of negative-pressure into the negative-pressure chamber 12e is suspended, and a subthrottle valve 10 is opened to an opening degree of, for example, 20. Further, the subthrottle valve 10 is perfectly opened in high-load operation.

Title: Water pouring device for external boiler type bathtub
Inventor: KATAOKA KATSUMI
IPC: F24H9/00
Filed: 1986-07-28
Abstract: PURPOSE:To improve heat exchange and slow down the cooling speed of bath water upon keeping temperature, by a method wherein a nipple, provided with a both-opened pouring port having the same diameter from an inlet port to an outlet port is penetrated through and attached to a valve seat while a thin diaphragm type non-return valve, opened and closed by a hydraulic pressure, is attached in parallel to the valve seat. CONSTITUTION:A nipple 2, provided with a both-opened water pouring port 1 having the same diameter from an inlet port to an outlet port, is penetrated through and attached to a valve seat 5, and a thin diaphragm type non-return valve 3, opened and closed by a hydraulic pressure, is attached in parallel to the valve seat 5 to constitute a water pouring device, which the water pouring device is attached detachably to the opening of a connecting pipe at the lower part of a bathtub among two connecting pipes between the bathtub and an external boiler. When water is poured through a hose connected to the cock of city water, a temperature difference is large since the low-temperature city water enters into the boiler directly upon heating, therefore, the heat exchange of the boiler is improved and heat conductivity is improved since the flow speed of the water is higher than in natural convection. The non-return valve 3 intercepts a circulating water flow passageway 4 upon keeping the temperature of the water after the fire of the boiler is put off therefore, the cooling speed of bath water may be slowed down.
