Title: Pipeline structure for solar heat water heater
Inventor: SAKAMOTO JUNICHI
IPC: F24H9/12
Filed: 1984-07-23
Abstract: PURPOSE:To prevent air lock, permit piping overriding a ridge and simplify water extraction by a method wherein a water feeding pipe is communicated with a hot-water delivery pipe through a branch pipe, the branch pipe is connected to the hot-water delivery pipe by a three- way valve and a vacuum breaker is provided at the connecting part between the water feeding pipe and the branch pipe or the vicinity thereof. CONSTITUTION:The three-way valve 14 is set by a remote control board 16 at a condition shown by (A) in the diagram and a water stop cock 5 as well as a hot-water delivery cock 9 are opened. According to these operations, water flows from the water feeding pipe 3 into the hot-water delivery pipe 7 through the branch pipe 15 whereby air, being stored in the hot- water delivery pipe 7, can be extruded by water supplying pressure and air lock is eliminated. Successively, when the three-way valve 14 is switched to a condition shown by (B) in the diagram, hot-water may be obtained continuously by siphon effect even in case of piping overriding a ridge which include a reverse slope. The tree-way valve is set in the condition shown by (A) and the hot-water delivery cock 9 is opened to extrude air in the pipeline. Thereafter, when the water stop cock 5 is closed and a water extracting cock 8 is opened, only water in the water feeding pipe 3 and the hot-water delivery pipe 7 may be extracted by the effect of the vacuum breaker 13. In this case, water in a hot-water reserving tank 2 does not flow out.

Title: Acceleration sensor and its manufacture
Inventor: ITO NATSUKO
IPC: H01L29/84
Filed: 1995-05-25
Abstract: PURPOSE: To provide an acceleration sensor whose temperature characteristic is good, whose S/N ratio is high and whose reliability is high in a capacitance-type acceleration sensor which measures an acceleration while a change due to an acceleration in the distance between opposite electrodes is detected as a change in a capacitance. CONSTITUTION: A stopper 41 has a structure in which an insulator frame 43 is arranged around a fixed electrode 42 whose material is the same as that of a moving electrode part 21. Thereby, parts whose coefficient of thermal expansion is different are reduced, and the thermal strain of an acceleration sensor can be suppressed to be small, and its sensitivity and its temperature characteristic are enhanced. In addition, the parasitic capacitance of a frame part 22 at the moving electrode part which is bonded to the stopper 41 is small because an insulator having a sufficient thickness exists between it and the fixed electrode part 42, and an S/N ratio is enhanced. Since the fixed electrode part 42 is used also as a stopper, it is not required to make a through hole in the stopper when a wiring operation is performed, and the electrode part can be worked easily.  When the structure of stopper 41 is formed and when the stopper 41 is bonded to a moving part 2, an electrostatic bonding method is used, and it is possible to manufacture the structure which is solid and whose reliability is high.

Title: Output circuit for transistor transistor logic circuit
Inventor: YOKOTA NOBORU
IPC: H03K19/013
Filed: 1986-06-30
Abstract: PURPOSE:To make the shoulder part of the leading edge of an output signal waveform steep by discharging an electric charge stored in a collector-base capacitance of an output transistor (TR) while the leading edge of the output signal is detected to eliminate the mirror effect. CONSTITUTION:A TR Q2 is conducted through the conduction of a TR Q1 with a terminal 10 at 'H' level, TRs Q3, Q4 being active loads are cut off and the level of a terminal 11 goes to L. The electric charge is stored in the collector-base capacitance of the TR Q2 in such a case. With the level of the terminal 10 at L level next, the TR Q1 is cut off and the TRs Q3, Q4 are conducted and the potential at the terminal 11 rises. Thus, the collector-base capacitance of a TR Q5 is charged rapidly and the TR Q5 is conducted. Then the TR Q5 detects the leading edge of the signal waveform at the terminal 11 to transfer it to a TR Q6. Through the electrification of the TR Q6, the charge stored in the collector-base capacitance of the TR Q2 is discharged rapidly. Thus, the shoulder of the leading edge of the output signal is made steep without the mirror effect of the TR Q2.

Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of an excessive response due to a sudden change in the concentration of gas without delaying a response speed and to lessen a space occupied by piping components, by providing a bypass passage in a state wherein the inlet and outlet thereof are connected to a sample gas passage and further by providing a piping of a large bore in the bypass passage. SOLUTION: Sample gas S of low concentration is supplied to an analyzing part 2 from a sample gas inlet 3 positioned on the upstream side of a bypass passage 4. When the sample gas S changes to be of high concentration suddenly at the inlet 3, the sample gas of high concentration goes separately into the bypass passage 4 and a sample gas passage 1 at the inlet (a) of the bypass passage 4. The gas of high concentration passing through a piping 1a is thinned with the gas S of low concentration flowing out from a piping 5 of a large bore. Meanwhile, the gas of high concentration passing through a piping 4a is also thinned with the sample gas S of low concentration likewise in the piping 5 of the large bore.  Accordingly, the sample gas can be supplied to the analyzing part 2, in a state wherein the change in the concentration is moderated finally in comparison with that on the upstream side of the bypass passage 4.
