Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent discharging of hot water of high temperature at the time of starting of feeding hot water and enable the temperature of discharged hot water to be controlled at a set temperature as mush as possible. SOLUTION: A hot water feeding passage 10 is provided with a bypass passage bypassing a heat exchanger 14 and mixing fed water at an outlet port of the hot water feeding passage. The hot water feeding passage is provided with a water amount adjusting means at the heat exchanger for controlling an amount of water at the heat exchanger, a temperature of hot water of high temperature within the heat exchanger is decreased at an outlet port of the hot water feeding passage through mixing at the bypass passage at the time of starting of feeding hot water where discharging of hot water of high temperature is expected and concurrently an amount of water at the water amount adjusting means G1 at the heat exchanger is controlled in reference to a deviation between the discharged hot water temperature at the outlet of the hot water feeding passage and the set temperature.  After a predetermined period of time after starting feeding of hot water, an amount of water in a water amount adjusting means at the heat exchanger is gradually increased while controlling with the aforesaid deviation along with reduction in temperature within the heat exchanger so as to prevent under-shooting of the temperature of discharged hot water. In turn, an amount of water of the water amount adjusting means at the bypassing side arranged in the bypass passage is gradually increased and similarly the temperature of the discharged hot water is maintained at the set temperature.

Patent JP-H0368895-A (JP)
Title: Fuel cladding tube for nuclear reactor
Inventor: YOKOTA NORIKATSU
IPC: G21C3/06
Filed: 1989-08-08
Abstract: PURPOSE:To enable a stress release by a deformation of a grooved part which is formed in a surface, and to prevent a breaking-down even if a tensile stress works on a fuel cladding tube by providing grooves which are parallel to an axial direction, in the inner surface of the fuel cladding tube. CONSTITUTION:A fuel cladding tube is made of a zirconium alloy 1, a ductile material 2 is lined on its inner surface and grooves 3 are formed in its surface. When a stress is generated on a fuel cladding tube due to a change of the reactor output, a circumferential tensile stress higher than that in the circumference works on the inner surface. In this situation, as the grooves are separated each other, the grooves themselves can be easily deformed and thereby the stress can be easily mitigated as well. Also, the grooved parts 3 can be easily and plastically deformed only at their surfaces and therefore the stress can be absorbed and propagation of cracks into an inner part of the cladding tube can be prevented. Consequently, a possibility of a ductile breaking-down is rather small even if an excess stress is generated by a PCI.

Title: Semiconductor laser device
Inventor: KUDO HIROAKI
IPC: H01S5/12
Filed: 1988-08-17
Abstract: PURPOSE:To obtain a connection efficiency which is equivalent to or more than a conventional secondary diffraction grid also in a third diffraction grid by setting the ratio of width between projecting parts of recessed and projecting parts for a period of recesses and projecting areas within a specific range. CONSTITUTION:Periodical recesses and projecting parts are formed at the interface between an n-type light guiding layer 6 and an n-type clad layer 7 to form a diffraction grid 12. The periodical recessed and projecting parts of this diffraction grid 12 are periodically continuous in the <011> direction and the groove formed by these periodical recessed and projecting parts extends in the <0-1-1> direction. The period of the recessed and projecting parts is set so that the diffraction grid may be the third one. A connection efficiency (k) due to difference of a duty ratio (W/LAMBDA) when the period of the diffraction grid is set to LAMBDA(3000Angstrom ) and the width of a projecting part 12a of the diffraction grid is set so that the duty ratio (W/LAMBDA) is formed to be closer to 0.20, 0.5, and 0.8 with the height H of the diffraction grid 12 being 1000Angstrom . Namely, the ratio of width of the projecting part of recessed and projecting parts for the period of the recessed and projecting parts stays within the range of 0.20-0.25, 0.40-0.60, and 0.70-0.95. At this time, even in a third rectangular waveform diffraction grid, a sufficient connection efficiency applied to a semiconductor laser device can be obtained.

Patent JP-H0254130-A (JP)
Title: Spectroscope
Inventor: KIKUKAWA TOMOYUKI
IPC: G01J3/02
Filed: 1988-08-17
Abstract: PURPOSE:To enhance measuring accuracy by correcting the shift of a focal position caused by thermal expansion/contraction by adhering reinforcing members different in a coefficient of thermal expansion to the rear of a collimator mirror and that of a camera mirror to forcibly correct a focal distance. CONSTITUTION:It is assumed that a substrate 1 is expanded and contracted by the thermal expansion and contraction caused by the temp. change around a spectroscope and, for example, the distance between a camera mirror 5 and an emitting slit 6 is changed by DELTAD. Of course, the focal distance of the camera mirror 5 or that of a collimator mirror 3 is ready to change by DELTAF. However, since reinforcing members 10 different in a coefficient of thermal expansion are bonded to the collimator mirror 3 and the camera mirror 5, the bending stress corresponding to the differences between the coefficients of thermal expansion of the collimator mirror 3, the camera mirror 5 and the members 10 acts on the camera mirror 5. As a result, the focal distances of both of the collimator mirror 3 and the camera mirror 5 are changed. Therefore, when the members 10 are provided so as to correspond to the shift quantity from the position of the slit 6, the focal position of the camera mirror 5 can be allowed to coincide with the position of the slit 6.

Title: Packing device for electric vacuum cleaner
Inventor: FUJITA MASAHIRO
IPC: B65D85/68
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent sideways sway, eliminate occurrences of scratches on a case, and reduce packaging cost, by bringing cut erection pieces, cut and bent from the bottom wall of a cushion, into contact with the wheels of the rear part of a vacuum cleaner, and by bringing a wing piece having an inclined cut in it into contact with the front bottom of the main body of the vacuum cleaner to support it. SOLUTION: Both cut erection pieces 8B of a corrugated board pat 6 are folded into vertical positions, both fold pieces 11B and 12B are folded into valleys, and the fold part of the fold piece 11B is folded into a mountain. Further, a wing piece 17 is raised to fold an auxiliary wing piece 18 into a mountain, and the entire pat is compactly stored into a box body 1. Then, a vacuum cleaner main body 2 prewrapped in a polyethylene bag 26 is stored onto the corrugated board pat 6 stored in the box body 1. Because, at this time, the front bottom of the vacuum cleaner main body 2 comes into contact with the inclined end of the wing piece 17, side-to-side movement of the front bottom is prevented. Further, the wheels 2B of the rear part come into contact with the cut erection pieces 8B, therefore side-to-side movement of the rear part of the main body is restricted.  This eliminates the need for an expensive polystyrene paper bag which is used for preventing the mirror-finished case of the main body from being scratched.

CONSTITUTION:When AC voltage is applied between a base electrode 3 and a toner carrying member 7 by an AC power supply 9, the toner 8 on a conductive material 7 is violently stirred between the base electrode 3 and the toner carrying member 7. When a wave-form (c) is applied between the base electrode 3 and the toner carrying member 7 from the AC power supply 9, the toner 8 on the toner carrying member 7 intends to move to the base electrode. When signal voltage (b) is applied to a signal electrode 1 from a signal power supply 11 at that time, the electric field passing the toner 8 works to the opening 4. When wave-form voltage (a) is applied between the base electrode 3 and a back electrode 6 from an AC power supply 10 under the state, the toner 8 reaches a recording member 5. A reverse wave-form is applied when the picture is not recorded.
