Title: Hot water temperature control device
Inventor: OHARA SUMIO
IPC: F24H1/10
Filed: 1989-02-07
Abstract: PURPOSE:To enhance the convenience of single operation at each service location by transmitting signals into a proportional control means which controls the quantity of heating and each control circuit which controls a water volume control valve and providing a single switch which sets and fixes the quantity of hot water supply. CONSTITUTION:When a hot water supply faucet 23 is opened to let water flow into a water circuit 23a, a signal from a water current detector 15 enters a control circuit 17 and its command actuates a proportional control valve 14 so that fuel may be fed to a burner 13, which is then ignited. A controller 20 controls the difference between a preset temperature and a signal transmitted from a temperature detector 18 in the outlet of a heat exchanger 12 at the control circuit 17 and controls the proportional control valve 14 so that detected temperature may conform to the preset temperature. The control circuit 17 also issues commands to a water quantity control valve 16 to drive so that the quantity of water supply may conform to the quantity of water predetermined with a signal from a single switch 21. This construction makes it possible to set and fix the optimum hot water supply temperature and the quantity of hot water supply at each service location only by manipulating the single switch and the hot water supply faucet interlocked with the single switch.

Title: Electric water boiler
Inventor: FUJII KAZUMI
IPC: A47J27/21
Filed: 1991-02-22
Abstract: PURPOSE:To provide an electric water boiler capable of controlling the heat retaining at a high temperature near the boiling point. CONSTITUTION:The temperature change quantity judging means 11 of a control circuit 11 judges whether the temperature change quantity of the water temperature is a preset value or below based on the output signal of a temperature detecting means 1. When the temperature change quantity reaches a preset value or below, a boiling control means 12 judges that water is boiling and continues the heating with a heat retaining heater 5b at the output lower than the heating output of a boiling heater 5a until the boiling is detected. A heat retaining temperature setting means 13 is set to the heat retaining temperature slightly lower than the detection temperature from a temperature detecting means 1 in the stable state when a fixed period elapses after the boiling is detected. A temperature comparing means 14 compares the heat retaining temperature and the detection temperature, and the heat retaining heater 5b is controlled by a heat retaining control means 15 in response to the comparison result. The heat retaining temperature can be determined without being affected by the water boiling heater 5a when the heat retaining temperature is set.

Filed: 1986-02-12
Abstract: PURPOSE:To prevent the reduction in an operating speed of a selection circuit by providing a voltage level correction means to the output of a switch element and operating the voltage level correction means in the timing treated more than that of a control signal of a switch element control line.

Title: Overlapped address check system
Inventor: HASHIMOTO KAZUAKI
IPC: G06F13/00
Filed: 1994-02-28
Abstract: PURPOSE:To perform the check of an MAC address where LLC sub-layers are overlapped, regardless of the control system of the MAC sub-layer in a LAN. CONSTITUTION:The subscription/connection of a LAN is performed, an XID command where a group address is preliminarily set is transmitted an opposite party and the XID command where the MAC address of its own device is set is transmitted to a transmission origin, in order to confirm whether other device having the same MAC address as its own device already exists or not (S21). The opposite party receiving the MIXD command transmits an XID response when the MAC address of the transmission origin is the same as the MAC address of its own device (D21, 22). Because the transmission side of the XID command receives two times XID responses of the XID response (S24) that its own device (LLC1) transmits and the XID response that the opposite device (LLC2) transmit, the transmission side cancels the both of the responses and leaves from the LAN because the device having the same MAC address as its own device already exists (S26).
