Title: Speaker structure for telephone set or interphone
Inventor: SUZUKI MASAHARU
IPC: H04M1/02
Filed: 1994-03-30
Abstract: PURPOSE:To reduce the installation space, to improve the performance of sounds, to reduce the cost, and to remove restrictions of the wiring length between a slave machine and a master machine on an interphone by providing a piezoelectric element as a speaker in an enclosure and forming a horn through which the acoustic signal from the piezoelectric element is led to the aperture part provided in the outside surface of the enclosure. CONSTITUTION:The oscillation which is caused by an input electric signal and is generated by a piezoelectric element 1 is led to a horn 4 from a rear face la of the piezoelectric element 1 and is sent to the out side of an enclosure 2 from an aperture part 3a. This oscillation is directly sent to the outside of the enclosure 2 from a front face 1b of the piezoelectric element 1 also through the other perture part 3b of the enclosure 2, and oscillations sent from aperture parts 3a and 3b are synthesized in a free space to obtain a sufficiently large sound volume. That is, when a proper acoustic resistance is given to the piezoelectric element 1 to improve the electroacoustic conversion efficiency in this manner, sounds emitted from front and rear faces 1a and 1b of the piezoelectric element 1 are synthesized in all of the surface of the enclosure 2 to secure the acoustic pressure level equal to or higher than that for speaker driving.

Title: Controller of hot water supplier
Inventor: EGAMI TOYOHIKO
IPC: G05D23/00
Filed: 1986-03-18
Abstract: PURPOSE:To stabilize the temperature of hot water supply by multiplying the rate of feed-forward elements before and after the variation of respective input values to a feed-forward operating part by integral components of a feedback operating part, and resetting the multiplied values as integral components immediately after the variation of the multiplied values. CONSTITUTION:When a supply hot water temperature Ts, an incoming water temperature Tc, and a supply hot water quantity Q have varies, a feed-forward operating portion 10 immediately calculates a feed-forward element Gff. The value of the element Gff is given to integrated value correcting means 16, and a division operator 16a calculates the rate of feed-forward elements before and after the variation. Successively, this ratio is multiplied by an integral component Gi. This multiplied value is reset as an integral component G'i immediately, after the variation. Accordingly, in accordance with the varied components of respective inputs Ts, Tc and Q, the integral component Gi of the feedback operating portion 14 are corrected to appropriate values, and hence no time lag is produced in the outputs of the respective operation results of the operating portions 10 and 14. Therefore, overchuting is eliminated.

Title: Television signal repeater
Inventor: OGINO MASAO
IPC: H04N5/38
Filed: 1983-04-08
Abstract: PURPOSE:To obtain a horizontally synchronous expanding circuit which deteriorates neither phase characteristics nor the cross modulation of a television repeater by employing circuit constitution which omits an intermediate frequency band-pass filter for separating a video and an audio signal component used for horizontally synchronous expansion. CONSTITUTION:A television signal received by the television signal repeater is converted by a frequency converter MIX into an intermediate frequency signal, which is amplified to a specific level and then applied to a pre-emphasis circuit PE. Then, a chrominance subcarrier and an audio carrier are attenuated by a specified amount from the video carrier, and a horizontal synchronizing signal is returned by the horizontally synchronous expanding circuit SE from compressed amplitude to original amplitude and then supplied to a de-emphasis circuit DE. This circuit allows the chrominance subcarrier and audio carrier to pass as they are. Then, the video carrier is attenuated by the same extent that the chrominance and audio carriers are attenuated by the pre- emphasis circuit PE, so the relative level relation among those chrominance subcarrier and audio carrier is reset to the state when they are applied to the premphasis circuit PE.

On a next field or next frame, the difference between the picture data in a motion vector detecting area around the positions of the respective representative points and the picture data of the representative points of the previous field preserved in the representative point memory 2 is obtained, an absolute value is obtained by an absolute value converting circuit 6, and inputted to a cumulative adder 7. The cumulative adder 7 cumulatively adds the data, and decides the place having the minimum value of the cumulatively added value by a minimum value address deciding device 8. Thus the circuit scale can be reduced.

Title: Bath hot water supply device
Inventor: IWAMOTO RYUSHI
IPC: F24H1/00
Filed: 1991-03-27
Abstract: PURPOSE:To make it possible to temporarily take a bath by a method wherein water leakage of a hopper is detected and if amount of leakage is small, discharge water operation is forcibly stopped so as not to allow operation to be performed more than predetermined times to shorten the period required for filling a bath tub with water and if the amount of leakage is large, water is supplied also from a discharge line. CONSTITUTION:Heated water of a hot water heat exchanger 15 is fed to a reheat line 3 via a hopper 17 from a merging point 8 to feed hot water to a bath tube 2 by direct pressure of a water supply system. The hopper 17 has a discharge water valve 19 which is opened to atmosphere when feeding hot water is stopped. Leakage of water from the valve 19 is normally small, but if malfunction of the valve 19 or inclusion of dirt occurs, the leakage increases. A water level detector 21 detects the leakage so that a controller 24 acts to treat the leakage in such a manner that, in case of small leakage, discharge water operation of a discharge water receiving part 20 is restrained, causing thereby interrupting hot water feed operation time of bathtub filling water. In case of large leakage, a discharge water line 11 connected to a reheat line 3 is utilized as a sub-hot-water-feed line.
