Abstract: PURPOSE:To make a low-frequency sound reproducing characteristic satisfactory by phase inverting a sound emitted from one side of a speaker and that emitted from the other side of the speaker and synthesizing them near the terminal part of an acoustic path. CONSTITUTION:The sound emitted from the front side of the speaker 4 is guided to the acoustic path 6 to reach the terminal of the acoustic path 6 and on the other hand, the sound emitted to the inside of a speaker housing box is phase inverted by a bass-reflex port 10. Then the phase-inverted sound and the front sound guided to the acoustic path 6 are synthesized and emitted from acoustic mouths 2 and 3. Then, the inside of a flat box 1 is separated into the acoustic path 6 and a box 7 to synchronize the sound from the box 7 near the acoustic paths 2 and 3 to emit it outside so that the speaker of a good low-frequency sound reproducing characteristic is obtained. Besides, the low-frequency reproducing characteristic is not damaged even when the capacity of the inside of a flat box 1 is small so that the speaker is miniaturized and its low-frequency sound reproducing characteristic becomes satisfactory.

Title: Method for discriminating propriety of transmission in full duplex communication
Inventor: HACHIGA HITOSHI
IPC: H04B1/50
Filed: 1987-12-25
Abstract: PURPOSE:To suppress the disturbance onto other radio installation by checking a transmission channel as well as a reception and channel permitting the start of transmission so long as it is confirmed that both the channels are idle. CONSTITUTION:Not only the reception channel 13 but also the transmission channel 12 is both checked in the discrimination whether or not the transmission from one radio station is to be allowed between at least a couple of radio stations employing the full duplex circuit having the transmission channel 12 being a reception channel to other party and the reception channel 13 being a transmission channel of the other party, and the transmission is not allowed before it is not confirmed that both the transmission and the reception channels are idle at present. Thus, the communication is not so much dependent on the transmission start timing between different radio installations and the possibility of production of a disturbing wave to other radio installation is well precluded.

Title: Heat exchanger
Inventor: YAMAMOTO KATSUHIKO
IPC: F24H9/00
Filed: 1988-12-23
Abstract: PURPOSE:To enable a non-power transfer of refrigerant to be carried out, provide a smooth flow of refrigerant and improve a heat exchanging efficiency by a method wherein the liquid refrigerant is uniformly heated by a refrigerant passage member formed with several longitudinal passages and an inlet of each of passages is formed with a metering part. CONSTITUTION:Liquid refrigerant passed through a refrigerant inlet pipe 21 and entered inlet header pipes 15 and 15 is dispersed from a metering part 14a of a lower part of a refrigerant passage member 13 into several longitudinal passages 14. A thermal transmitting spaced-apart wall member 10 may absorb heat of combustion discharged gas passing through thermal transmitting fins 17 at a parallel approaching surface 12 provided with the thermal transmitting fins 17 through a combustion heat shielding cylinder 18 from a combustion chamber 19. The refrigerant within the longitudinal passages 14 of the refrigerant passage member 13 thermally connected is sufficiently heated from a lower part near the inlet header pipe 15. The liquid refrigerant flowing from the inlet header pipe 15 is uniformly distributed into each of several passages 14, the refrigerant may be prevented from being reversely flowed due to a pressure variation generated when the liquid refrigerant is evaporated. A natural circulating force is increased and an effect of agitating turbulence flow is generated by an upward rising flow from the lower part and the local abnormal over-heating of the refrigerant is prevented.

Title: Galvanomirror
Inventor: IDE TSUGIO
IPC: G11B7/09
Filed: 1989-12-18
Abstract: PURPOSE:To obviate the disconnection of feeders and to facilitate assembly by using a permanent magnet subjected to radial multiple magnetization as a rotor and providing braking adjustment mechanisms. CONSTITUTION:The permanent magnet 4 subjected to the multiple magnetization in the radial direction is the rotor supported by bearings 3, 9. A mirror 1 is fixed to the front end of a supporting shaft 2. Driving mechanisms 5, 6 and the braking adjustment mechanisms 7, 8 are disposed by having a specified distance from the magnet 4. The state in which the tooth 10 of a stator core 5 for driving faces the boundary position between the N pole and S pole of the magnet 4 is the oscillation center of the rotor. While the stator core 7 for braking is so fixed that the position of the tooth equals to the stator core for driving, this position may be shifted by half the pitch of the magnetization pitch of the magnet 4. The rotor generates a rotational displacement in both directions from the oscillation center by the current direction of the coil 6 for driving, by which the optical axis of the incident laser beam on the mirror 1 is oscillated.

Filed: 1990-11-27
Abstract: PURPOSE:To allow the operator to recognize the result of transmission even when transmission is failed due to a fault of its own equipment by allowing an opposite equipment to return part of an original having just been sent by its own equipment through polling by means of a telephone reservation and printing out the result of reception together with a transmission report. CONSTITUTION:The processing of a sender side is finished when no reply signal comes from a receiver side and a timer 5a expires, and a DTMF transmission circuit 6 sends a polling request signal to the receiver side through a telephone line 1. Then a time of 16sec is set to the timer 5a and the sender side awaits a polling reply signal from the receiver side. The processing of the receiver side is finished when no reply signal comes from the sender side and a timer 5b expires, and when the receiver side receives a request, the receiver side sends the polling reply signal to the sender side through a MODEM 2 and the line 1 and sends the received content stored in a memory 9 to the sender through the MODEM 2 and the line 1 according to a normal transmission protocol and then the processing is terminated. Thus, when an original cannot normally sent due to a fault of its own equipment, the fault is recognized.

Title: Contour emphasis device
Inventor: ROKUSHA KAZUHIKO
IPC: H04N1/409
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To display an easy to see text image by conducting the processing of emphasizing a contour component of a video signal to be deteriorated through band limit so as to compensate the deteriorated contour component. SOLUTION: A digital video signal S41 received from an input terminal 40 is given to a nonlinear processing section 10 and a maximum value/minimum value/mean value calculation section 11 respectively. The maximum value/ minimum value/mean value calculation section 11 calculates a maximum value, a minimum value and a mean value from the input digital video signal and gives them to the nonlinear processing section 10. The nonlinear processing section 10 uses the maximum value, the minimum value and the mean value to apply nonlinear processing to the input digital video signal S41 and provides an output. In this case, the arithmetic processing is conducted in a way that the input level is smaller when the input level is smaller than the mean value and the input level is higher when the input level is higher than the mean value.  The deterioration in the contour component due to band limit processing of an LPF is compensated and the contour is emphasized. A text image such as clear character or the like is displayed.
