Title: Forced circulation bath boiler
Inventor: HIBINO MINORU
IPC: F24H1/00
Filed: 1984-10-25
Abstract: PURPOSE:To prevent freezing during a winter season by expelling all water from the piping and yet facilitate the priming of a circulating pump when the bath boiler is going to be used by providing a three-way valve in a water circulating passage on the sucking side of the circulating pump as well as a water drain valve in a priming water supply passage and the water circulating passage. CONSTITUTION:When the drain switch is turned on, a shutoff valve 12 is closed, a drain valve 15 is opened, and a three-way valve 6 is actuated to communicate a communicating pipe 7 with a circulating pump 4. After a certain time required to completely drain a reservoir tank 8 has elapsed, the communicating pipe side 7 of the three-way valve 6 is closed and the feed pipe side 5a opened to drain all the water in a water circulating passage 5. After the drain switch is turned off and the drain valve 15 closed, hot water is supplied to a bathtub 1 through a hot water discharge pipe 10 of a water heater 3. A supplemental heating switch is turned on and the shutoff valve 12 is opened to supply water to the reservoir tank 8 from the water heater 3 via a branch pipe 11. At the same time, the three-way valve 6 is switched to allow the flow between the communicating pipe 7 and the circulating pump 4 to supply the priming water to the circulating pump 4 from the reservoir tank 8.

Title: Magnetic recording medium
Inventor: ANDO KUNIO
IPC: G11B5/738
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium in which a surface electric resistance is lowered and in which dust articles are hard to stick by a method wherein a granular and nonmagnetic Mn-containing iron oxide particle is contained in at least one out of a magnetic layer, an intermediate layer and a back layer. SOLUTION: A granular and nonmagnetic Mn-containing iron oxide particle is set preferably in such a way that its mean particle size is 0.05 to 0.5 μm, that its specific surface area is 2 to 15 m<2> /g and that its moisture content is 5% or lower. Thereby, a surface electric resistance is lowered, and dust particles are hard to stick. As result, the durability and the running property of a magnetic recording medium are enhanced. Then, the dropout of the magnetic recording medium is reduced, and its recording and reproducing characteristics is excellent. In addition, when the granular and nonmagnetic Mn-containing iron oxide particle is contained in a magnetic layer, especially a magnetic head is hard to clog, its dropout is hard to generate, and its running durability is made good. In addition, when the particle is contained in a back layer, especially the running durability of the magnetic recording medium is made good. When the particle is contained in an intermediate layer, the dropout of the magnetic recording medium is hard to generate, and its running durability is made good.

Abstract: PURPOSE:To obtain a water base ink recording sheet having excellent ink absorptivity and ensuring little spreading of recorded dots and high density of recorded dots, by applying a coating material comprising a partial neutralizate of a specified polymer and a hydrophilic resin to a base, followed by heating. CONSTITUTION:Either an acrylic acid polymer consisting of polyacrylic acid or polymethacrylic acid or a maleic anhydride copolymer comprising alpha-olefin or vinyl compound and maleic anhydride is partially neutralized by sodium hydroxide, potassium hydroxide or the like to a neutralization degree of 20-70%.

Patent JP-H0388503-A (JP)
Title: Piezoelectric oscillator
Inventor: UCHIDA TAKASHI
IPC: H03B5/32
Filed: 1989-08-31
Abstract: PURPOSE:To preclude the jump phenomenon of an oscillation frequency when the temperature in a thermostatic chamber is raised in the initial state after power is turned on until a constant temperature is reached by setting the operation level of the initial state of a transistor(TR) for oscillation lower than in the subsequent constant state. CONSTITUTION:A division resistance which determined the base bias of a TR 10 for switching consists of temperature sensing resistance networks 11 and 12. The resistance temperature characteristics are so set that the TR 10 is turned off in the initial state wherein the temperature in the thermostatic chamber is below Ttheta deg.C and turned on in the constant state wherein the Ttheta deg.C is exceeded. Consequently, the power-source side resistance value of the TR 2 for oscillation nearly equals the sum of resistances 8 and 9 in the initial state after the power source is turned on. In the constant state, the resistance value on the power source side is almost only the value of the resistance 9. Therefore, the bias voltage of the TR 2 is high in the initial state and high in the constant state. Then a decrease in vibration level precludes the jump phenomenon from main vibration to subordinate vibration.

Abstract: PROBLEM TO BE SOLVED: To provide a variable damping device stably operated against various factors. SOLUTION: A double rod type piston 3 is installed slidably into a cylinder 2. A flow control valve 12 is mounted in a flow path tying the left and right hydraulic chambers 6 of the piston 3. A computer 14 inputs a damping-force command value S1 to a damping force controller 13 on the basis of the response of a structure. Actual damping force generated in a device 1 is detected in the forms of hydraulic detecting values S6, S7 by pressure sensors 23 fitted to both hydraulic chambers 6.
