Title: City water heating device
Inventor: MIYAMOTO AKIO
IPC: F24H1/00
Filed: 1982-05-20
Abstract: PURPOSE:To heat city water in a heat exchanger efficiently by a method wherein the city water is heated by heat from an electrical apparatus such as a transformer. CONSTITUTION:A cooler 2 is adopted to cool an insulating oil in the transformer 1 through its fan 3. The heat exchanger 4 is arranged in opposite relationship with the cooler 2 and so the city water in the heat exchanger is heated by hot air from the fan 3. In winter, valves 5 and 6 are opened and a third valve 7 is closed so that water in the upper part of a pipe 13 passes through the heat exchanger 4. The city water is then heated by the hot air from the fan 3 as it passes through the heat exchanger 4 and is stored in a water tank 9 through the valve 6 and a water pipe 10. As the water tank 9 is insulated from heat, the water stored therein is not cooled soon.

IPC: G05B15/02
Filed: 1988-04-11
Abstract: PURPOSE:To discriminate whether an operator touches a storage device or not by detecting the potential or the waveform change through a conductor provided on the storage device. CONSTITUTION:The surface of a memory card 2 is coated with a conductor like a metallic foil, and a touch sensor controller 5 is connected to an electrode 4. The touch sensor controller 5 detects a signal having a prescribed frequency from the conductor brought into contact with, for example, the electrode 4. An AC noise of 50-60Hz low frequency is normally generated in the human body; and when the controller 5 detects this signal, it is judged that the operator's finger touches the memory card 2, and an interrupt signal is outputted to a CPU 1. A buzzer 6 is connected to the CPU 1 so that a warning is given at the time of touching an IC cad during the access to the memory card 2. Thus, the warning is given at an early timing because the touch is detected at the movement of touch of the memory card 2.

Abstract: PURPOSE:To eliminate pilot flame and to ensure safety in case a device fails in reignition when flame goes out half-burnt, by a method wherein a device is automatically ignited only through control of a cock, and an electromagnetic value is closed in case the flame goes out half-burnt. CONSTITUTION:With cocks 3a and 3b opened, water flows through a water passage 1, S1, S2 and S3, serving as a water-jet switch 2 are all turned ON, and spark discharge is caused at an ignition electrode 7 to effect ignition. In case combustion of a burner 6 goes out half-burnt, and a current is prevented from flowing through a flame detecting body 8, whereby a transistor 19 is turned OFF to demagnetize a coil 20, and spark discharge is produced again to effect ignition. In case a device fails in reignition, since S3 and S4 are turned ON and the coil 20 is demagnetized, after a time set by a timer consisting of a resistance R1 and a capacitor 25 has elapsed, a transistor 24 is turned ON, the electromagnetic valve is closed to automatically stop supply of gas. This permits ignition of a device without using a pilot flame, and enables to prevent leakage of gas.

Abstract: PURPOSE:To mount on a correct position by disposing a positioning member at a relative position with lead pins. CONSTITUTION:Lead pins 1 are disposed at four sides of a resin mold 2, positioning members 3 are disposed at four corners of the mold 2, and the material is the same as copper alloy as those of the pins 1. A positioning hole 3a is formed at the member 3. Since the member 3 is formed integrally with the pin 1 at a lead frame, the relative-positional accuracy of the member 3 to the pin 1 depends only upon the punching accuracy of the frame to be extremely accurate. Since the member 3 has a short protruding part from the mold 2, it is not bent. Thus, it can be accurately positioned with the member 3 as a reference.

Title: Manufacture of heat resistant substrate
Inventor: SHIROGANE JUNJI
IPC: B05D7/24
Filed: 1985-04-24
Abstract: PURPOSE:To prevent the deterioration of the polyimide on a substrate, by using aluminum as a metal base material and directly forming a polyimide layer to the surface thereof. CONSTITUTION:In manufacturing a heat resistant substrate used in a printed wiring board, an aluminum base material or a base material of which the surface is covered with metal aluminum is used as a metal base material. Polyamide acid or polyimide varnish is directly applied to the surface of the metal base material and dried and cured to make it possible to directly form the polyimide layer on the metal base material. Because the deteroration of the polyimide layer is generated by the reaction of the copper (II) ion occurring from a copper base material and polyimide in the presence of oxygen, said deterioration is suppressed to a large extent when aluminum is used.
