Title: Electric boiler
Inventor: URATA TAKAYUKI
IPC: C02F1/20
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To devise so that water in an electric boiler with water purifying functions can be boiled up without leading any external air smell and the like thereinto and in generating almost no steam. SOLUTION: This is composed of a feeder 12 arranged in the mid-course of circulation route and a pump 8 to circulate water after heating up a heater 20 to get water contact with the internal air in the vessel 2. This allows the volatile ingredients in water to be transferred into air without leading any external air into the vessel. This can, therefore, produce an electric boiler capable of purifying water without leading any external air smell and the like thereinto and in generating a very few of steams only.

Title: Actuator for electric meadow fence
Inventor: JIEREMII JIYON MATSUKISATSUKU
IPC: H05C1/04
Filed: 1988-05-26
Abstract: PURPOSE: To reduce radio wave failure as well as efficiently supply pulses to a meadow fence by internally detecting the load of an energizing device so as to control pulse output from plural signal generating means via a control means. CONSTITUTION: A parameter corresponding to a load via a load detection wire 7 connected to a pulse shaping circuit 6 for forming an energizing device together with pulse generators 2, 3 formed by a transformer, etc., is internally detected by a control circuit. In response to this detection, the thyristor switches of the generators 2, 3 are controlled by a control circuit and one side output pulse out of generators 2, 3 or both output pulses are supplied to the circuit 6 so that pulse electric power applied to electric meadow fences may be controlled in response to the load. Accordingly, pulses may be efficiently supplied to the meadow fences and also a radio wave failure may be reduced by supplying adequate pulses in comparison with supply of excessive pulse.

Title: High pressure fuel feed pump
Inventor: ISOZUMI SHUZO
IPC: F04B53/16
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent the seizure of a plunger by providing the plunger capable of reciprocating within the sliding part of a cylinder and a slit in the fixed part of the cylinder. SOLUTION: A cylinder 32 is attached on between a delivery valve 10 and a pump main body 17. An annular fixed part 33 is formed in the upper part of the cylinder 32, and the compressing force in the longitudinal direction is received when the pump main body 17 and the delivery valve 10 are threadably attached to each other. A cylinder sliding part 34 is extended in the longitudinal direction integrally from the fixed part 33, and an annular slit part 35 is formed in the lower end of the fixed part 33. Since a plunger 23 is smoothly reciprocated vertically in the cylinder sliding part 34 during its reciprocation in the cylinder 32, the seizure of the plunger 23 is completely prevented. By providing the slit 35, sealing is secured both between the delivery valve 10 and the cylinder 32 and between the pump main body 17 and the cylinder 32 and fuel leakage is reduced.

Title: Keyboard cover opening/closing device for keyboard musical instrument
Inventor: YAMASHITA NOBORU
IPC: G10C3/00
Filed: 1988-05-24
Abstract: PURPOSE:To assure silent turning and to decrease the uncomfortability by noises by constituting the title device in such a manner that the weight of the keyboard cover is supported by the recovering force of a spring at the beginning of turning of the cover and the cap is pressed gently to the body by the braking force generated by the viscous resistance of a viscous body in the end period of the turning. CONSTITUTION:The keyboard cover 101 is stably detained in an open position by the weight body while the cover 101 is in an open state. The control force is generated against the force which tends to close the cover by the recovering force of the weight body in succession to the above in an initial period at the time when then cover is turned toward the close position. The turning force generated in the cover 101 is transmitted through a shaft body 105 to a rotary damper 107 and when the cover 101 arrives at the intermediate position from the close position, the torsion of the coil spring 125 increases and, therefore, the recovering force occurring in the elastic force thereof balances with the force trying to close the cap 101, thus acting the braking force upon the cover. The turning speed increases thereafter upon approaching to the close position, but the relative speed of the damper 107 with a case 111 and the shaft body 105 increases and the viscous resistance of grease increases so that the cap 101 is gently pressed to the body.
