Title: Ignition timing control device for internal combustion engine
Inventor: FUJIMOTO TAKANORI
IPC: F02P5/15
Filed: 1987-05-22
Abstract: PURPOSE:To enhance engine output very much and control knocking with high accuracy by providing an integrator for integrating the output of a knock discriminator and a reset means for reseting the integrated value corresponding to ignition operation. CONSTITUTION:A cylinder pulse generator 21 generates a cylinder pulse at the predetermined crank angle position corresponding to ignition operation. An acceleration sensor 1 detects the vibration acceleration of an engine. An integrator 24 receives a knock pulse from a comparator 6 and outputs integrated voltage proportional to the time width of the pulse. A reset means 15 outputs a reset signal to the integrator 24 upon receipt of the cylinder pulse and output from a microcomputer 13. In this way, a knock amount per each cylinder can be detected in proportion to a generated knock amount, and engine output can be enhanced very much. Also, knocking can be controlled with high accuracy.

Title: Starter
Inventor: EBIHARA KOUHEI
IPC: F02N11/00
Filed: 1978-10-18
Abstract: PURPOSE: To facilitate the axial slide of a pinion sleeve and to provide sufficient durability to low-speed high-load and low-load high-speed operations by bearing the sleeve on a bearing consisting of a combination of plural balls and a sintered oilless bearing parallel with the balls.  
     CONSTITUTION: With an engine started by operation a magnet switch 18, since the gear ratio between a pinion 9 and an engine-side ring gear 10 is large, the pinion 9 is rotated at high speed even if the engine revolution rate is small. In this case, although a one-way clutch 8 functions to prevent an overrunning on the side of a spline tube 5, the pinion 9 and a pinion sleeve 7 rotate at high speeds and the circumferential speed of the bearing 11 is high. However, it is when the pinion 9 is reversely driven by the ring gear 10 that the sleeve 7 rotates at high speed; since the sleeve 7 is in an overrunning condition at the clutch portion 8, the load on the bearing 11 is so small that it can be born by only the balls 13. Thus, the bearing 11 can endure high rotation sufficiently.

Title: Hot water mixing control device and hot water feeding apparatus having hot water mixing control device
Inventor: OTANI TAKAYUKI
IPC: F24H1/10
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To enable an inside part of a pipe to be filled with suitable temperature water for preparation of re-discharging of hot water without deteriorating a function to add water by a method wherein a target distribution ratio is calculated in response to a restricted distribution ratio determined in response to a mixing flow rate of hot water and cold water. SOLUTION: As a water adding operation is instructed by a user through a remote controller or the like during a stopped state of combustion, a bath opening or closing valve 43 is opened and water is supplied to a bath tub. As a desired amount of water is attained in reference to a detected value of a bath water amount sensor 45, the water adding operation is completed. Then, combustion is started in such a way that the inner sides of a hot water supplying pipe 5 and a branched pipe are filled with hot water of appropriate temperature in preparation for re-discharging of hot water. At this time, a mixing valve 31 is controlled in such a way that the ratio may become a target distribution ratio of the mixing valve 31.  With such an arrangement as above, since a flow rate of hot water at the mixing valve 31 is adjusted to be restricted, a temperature of hot water at an outlet of a heat exchanger 7 becomes a high temperature in a short time and thus it is possible to prevent surplus hot water of sufficient temperature from flowing in the bath tub.
