Title: Loudspeaker telephone set
Inventor: HORIUCHI TAKESHI
IPC: H04M1/60
Filed: 1989-06-26
Abstract: PURPOSE:To avoid the unpleasantness of an opposite party by opening a reception switch when the mode is switched from the reception mode into the transmission mode and adjusting the output period of a control signal to both switches so as to close the transmission switch after the point of time when the vibration of an electric/acoustic converter is vanished. CONSTITUTION:When a reception switch 8 is closed and the mode is switched from the reception mode opening a transmission switch 3 to transmission mode opening the reception switch 8 with the closed reception switch 8, the output period of a control signal to both switches 3, 8 is adjusted to close the transmission switch after the vibration of an electroacoustic transducer 1 is vanished by opening the reception switch 8. Thus, it is prevented that the echo sound is listened to the opposite party due to the delay of reply of the electric/acoustic converter 1 when the mode is switched from the reception mode into the transmission mode through the end of talking of the opposite party. Thus, a loudspeaker telephone set without giving the unpleasantness to the opposite party is obtained.

Filed: 1986-07-11
Abstract: PURPOSE:To obtain the excellent picture without convergence error by providing two magnetic field control elements comprising annular and tongue portions, which are opposedly arranged on the bottom of a shield magnetic pole disposed in an electron passing region which is subjected to the effect of the deflected magnetic field of an electron gun rear end portion in an electromagnetic deflection device. CONSTITUTION:A magnetic field control element 80 comprises an annular portion 81, made of high permeability magnetic material, perfectly surrounding external electron beam apertures 16R and 16 B located on the bottom of a shield magnetic pole 16 and a tongue portion 82 continously extending to the annular portion 81 on the central electron beam aperture 16G side.

Title: Interference wave erasing circuit for sonar device
Inventor: SAKAMOTO KENSHIN
IPC: G01S7/536
Filed: 1986-07-11
Abstract: PURPOSE:To erase an interference wave by sending an mean value output obtained before the generation of mutual interference to a CRT at the time of detecting a ring-like interference wave. CONSTITUTION:A detecting output signal (a) obtained from a preprocessor 20 is outputted to a mean value circuit 5, delay circuits 7 formed in plural channels 40a-40n, 50a-50n and a capacity comparator 1. The signal (a) inputted to the comparator 1 is compared with a reference level VL1 applying high luminance to a screen and an AND circuit 4 decides whether a logical signal (d) is a ring-like interference wave or not, and in case of the interference wave, outputs a control signal (e). On the other hand, the signal (a) inputted to the circuit 5 is turned to an averaged level signal (g) and an output (h) obtained through a sample holding circuit 6 is supplied to respective switches 8 in the CH 40a-40n. The switches 8 usually supply the outputs (f) of the circuits 7 to a post processor 60, but when the signal (e) is in the 'H' level, generates the output (h) of the circuit 6. Namely, the output (h) of the circuit 6 is selected at the time of formation of the high luminance ring-like wave to erase the interference wave so that high luminance ring-like display is not generated on the screen of the CRT 70.

Title: Mold
Inventor: MORIMOTO TAKASHI
IPC: B29C45/33
Filed: 1985-07-24
Abstract: PURPOSE:To make a forcibly returning device unnecessary and to make cost down and shortening of a cycle possible, by setting notches at a slide core in order that the slide core and a projected pin do not interfere with each other while they are moving for operation. CONSTITUTION:When a mold is closed, a slide core 3 and a projected pin 2 do not collide with each other if a point B which is on right hand side and below the slide core is above a line C which is drawn from a point A being on left hand side and above the projected pin with an angle of theta deg.. Namely, if notched parts 13 are made within the range of hatched part 12, the projected pin 2 does not collide with the slide core 3. But if the notched parts are too large, a molding becomes too thick and the cooling cycle becomes too long. If the projection is made with the cooling cycle being short, no effect of the projected pin is obtained as the thick part is projected without being solidified. It is therefore made possible to put the projected pin below the slide core by making the size of the notches minimum.

Title: Plate-like object to be plated continuous transferring device in plating device
Inventor: OBA KAZUO
IPC: B65G49/02
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To realize a smooth whole transfer without stumbling by disposing at a forward inclination an upper end of a driving roller to previously contact a lower end with a plate-like object to be plated and to previously move a lower end portion of the plate-like object to be plated. SOLUTION: The point that a plate-like object 3 to be plated of which both surfaces are clamped by vertical rollers 4, 4... including a driving roller 4' is conveyed on a rail 2 having a V shape cross section is the same as the prior art, however, the driving roller 4' is disposed so as to forwardly deviate an upper end portion from a usual dotted line position with an angle α. Thus, a lower end o the plate-like object 3 to be plated is previously contacted with the driving roller 4' and an upward force of an arrow mark is acted on a tip end lower portion F. Therefore, even if a downward stumbling force is acted on the tip end lower portion F, the downward force is denied by the upward force and a smooth conveying can be always realized. The number of the driving rollers 4' can be appropriately changed depending on a size and a length of a device.

Title: Defoaming device for magnetic fluid
Inventor: HORI NAOKI
IPC: B01J19/08
Filed: 1987-06-30
Abstract: PURPOSE:To surely discharge the air bubbles mixed in a magnetic fluid in a short time by defoaming the fluid in a magnetic field gradient obtained by arranging a magnetic force source in the vicinity of a vessel so that the magnetic field is progressively lowered in the flow direction of exhaust gas. CONSTITUTION:The magnetic field is directed as shown by H in the magnetic fluid storage part in the defoaming device, and the magnetic filed is progressively lowered toward the upper part of the vessel 1 by a permanent magnet 8. Accordingly, when a vacuum pump 6 is operated, magnetic floating force acts on the air bubbles 7 which are nonmagnetic and mixed with the magnetic fluid 2 in the vessel 1 in the flow direction of the exhaust gas, i.e., in the direction as shown by the arrow V, the air bubbles 7 move rapidly in the direction V, and the defoaming capacity and efficiency are improved. Moreover, since the magnetic fluid 2 is surely retained on the lower side of the vessel 1 during defoaming, the magnetic fluid 2 is not splashed by the burst of the air bubbles 7, and the deposition of the fluid on the upper inner wall surface of the vessel 1 and on the inner wall surface of a chamber 3 can be surely prevented.
