Title: Dry process tap water meter
Inventor: TAKUMI HIROYUKI
IPC: G01F15/07
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent the blur of the lower surface of window glass and the lower surface of a blur prevention plate and to facilitate meter-reading by arranging a transparent blur prevention plate made of resin between the upper portion of a numeric wheel and the window glass and setting the gap between the blur prevention plate and the window glass to a specific value or less. SOLUTION: A transparent blur prevention plate 12b made of resin is arranged between the upper portion of a numeric wheel 9 and window glass 14 while a gap D to the window glass 14 is set to 0.4 mm or less in a register box 1. The water of a tap water entering an indication mechanism part A enters the gap D from the opening edge of the gap D and forms dew on the lower surface when the temperature of the window glass 14 is low. However, since the gap D is narrow (0.4 mm or less), condensation does not become water drop and grows into a water film where the thickness of the gap D is uniform, and the lower surface of the window glass 14 cannot be blurred.  Also, since the resin material of a blur prevention material 12b has a large heat content than glass, water centrally adheres to a lower surface 14a without the blur prevention plate 12b and not condensation (blur) is generated on the lower surface 12b of the blur prevention plate 12b, thus enabling the numbers of the numeric wheel 9 being located at the lower portion of the blur prevention plate 12b to be read.

Title: Vibration damping mechanism of vane in axial-flow rotary machine
Inventor: HAGIWARA NORIAKI
IPC: F04D29/34
Filed: 1981-03-02
Abstract: PURPOSE:To improve damping effect of the vane without reducing fluid performance of an axial-flow rotary machine in such a way that a laminate metal piece is inserted between a rotor and the dovetail of a vane, and both ends of the laminate metal piece are brought into contact with the appropriate region of the vane plane. CONSTITUTION:A laminate metal plate 7 equipped with a groove part 7a is inserted into a dovetail part 1 which is a connection of a vane 2 and a rotor in a rotary machine. At the part where the metal piece 7 is brought into contact with the dovetail part 1, it is made into almost the same length and width as the dovetail part 1, while at the part where it gets out of place from the dovetail parts on both end sides of the metal piece 7, the width is narrowed, it is brought into contact with the bent face of the vane surface under the pressure of the contact surface, and the gap to the vane surface is reduced so as not to bring turbulence of fluid. Thus, damping effect of the vane 1 can be at all times maximized within operating region, and fluid performance is in no case to be lowered.

Filed: 1983-02-23
Abstract: PURPOSE:To reproduce a transmission picture signal of facsimile broadcast such as synoptic chart with fidelity and to improve the transmission speed by supplying an intermediate frequency signal to a PLL so as to obtain a frequency shift demodulating output. CONSTITUTION:When a broadcast signal frequency-converted into an IF band is applied to an IF band FS (frequency shift) demodulator 20, a phase comparator 20a compares the phase and frequency of the IF band FS signal input with those of an output of a VCO20c and an FS demodulating output is obtained from a low pass filter 20b. In this case, the delay time in the demodulated output of the PLL20 at a transient point of time is practically negligible even to the sampling period of a printer, the problem of delay of white/black signal changing point of a reproduced picture to the transmitted original picture is eliminated and a minute detailed part is reproduced with fidelity. Since the reference frequency of the PLL is increased, the circuit copes quickly with the change in white and black picture signals.

CONSTITUTION:In the case of slicing a cooking material 38, a push-in bar 35 slides downward along an inner wall of a cylindrical opening part 32 of the upper face of a cover 31, and a holding plate 36 of the lower end of the push-in bar 35 slides downward along an inner wall of the cover 31. Accordingly, a scratch is generated on an outer wall of the push-in rod 35 and the inner wall of the cylindrical opening part 32, and the inner wall of the cover 31. However, since a flange 33 is formed on the inner wall of the upper end of the cylindrical opening part 32, and thin longitudinal ribs 37, 34 are formed on the outside periphery of the push-in bar 35 and the inner wall of the cover 31, the contact is not executed by the face.
