Title: Howling preventing method for loudspeaking simultaneous call interphone and said interphone
Inventor: SUZUKI MASAHARU
IPC: H04M1/62
Filed: 1978-09-09
Abstract: PURPOSE:To ensure a highly effective prevention for the howling with the loudspeaking simultaneous interphone by installing the sound reception face of the sound wave entering the microphone at the back of the radiation face of the sound wave arriving from the speaker. CONSTITUTION:Sound reception face 20 of the sound wave entering mike 12 is put at the back to radiation face 16 of the sound wave snet from speaker 14. Mike 12 is connected to adder circuit SIGMA via phase shift circuit tau of pi-radian, and mike 12' is connected directly to circuit SIGMA. But these two mikes have the different distances from speaker C and different phases, thus obtaining output S. And this output rings the speakers of the interphones of the same structure, and this ringing is added to the two mikes in the equal distance and the opposite phases to produce no output. As a result, no howling is caused through the interphone of the self-side. Circuits tau and SIGMA can be realized by the distribution and connection of the two mikes. As a result, the acoustic coupling can be blocked at the high range via the directivity and the diffraction effect of the sound wave, and also the acoustic coupling can be prevented at the low and intermediate ranges by the opposite phase addition of plural mikes. Thus the howling can be avoided.

Abstract: PURPOSE:To improve the durability of a bearing, by forming a low pressure oil introducing hole in a low pressure area of a cover and suction ports, which communicate with this hole, to be deflectively located in an opposite side to the cover from the center of face width of a gear. CONSTITUTION:A low pressure oil introducing hole 54 is provided in a low pressure area in the side of a cover 7, and the hole 54 maintains its depth reaching 1/3 or more times the effective length of bearing holes 8, 9. The low pressure oil introducing hole 54 communicates with suction ports 55, 56 through chambers 44, 45. The ports 55, 56 are formed deflecting in an opposite direction to the cover 7 from the center of face width of both gears 12, 15. Accordingly, the low pressure oil introducing hole 54 maintains its inside always in a low temperature, and also the inside of roll bushes 10, 11 is forcedly cooled, thus a bearing enables its durability to be enhanced by high increasing the viscosity of working fluid.

Title: Cold trap device
Inventor: ENDO KAZUYA
IPC: H01J37/18
Filed: 1993-05-13
Abstract: PURPOSE:To simplify the handling and to secure the safety by cooling a trap by using a thermion cooling element. CONSTITUTION:In a vacuum container 9 whose vacuum is maintained by a vacuum exhaust pump 10, a thermion cooling element 1 absorbs the heat from a trap 3, and the cooled trap 3 absorbs the molecules in the container 9. On the other hand, the heat absorbed from the trap 3, and the internal heating of the element 1 are carried out of the vacuum by a heat pipe 2, air cooled or liquid cooled in a heat sink 5, and then exhausted. When the container 9 is made at the atmospheric pressure, the polarity of the feeding power of a power source 7 is reversed, and the cooled trap 3 is heated to restore to a normal temperature, so as to prevent the dewing. The heat of the pipe 2 is absorbed, and the pipe 2 is cooled, but the reduction of the temperature of the pipe 2 up to the dewing is prevented by the residual heat in the pipe 2. By such a way, the cooling and the restoring to the normal temperature of the trap 3 can be carried out by only feeding a power, and the safety and the simplicity of handling of a cold trap device can be improved.

Title: Multi-cylinder internal combustion engine
Inventor: KUMAGAI SEIICHIROU
IPC: F02B75/18
Filed: 1979-08-31
Abstract: PURPOSE: To reduce the concentration of NO x , CO and HC in the exhaust gas by dividing the cylinders into a group, to which excessively rich air-fuel mixture is supplied, and a group, to which excessively lean air-fuel mixture is supplied, and providing a thermal reactor for receiving the exhaust gas produced from both the air-fuel mixtures and an ignition timing adjusting means.  
     CONSTITUTION: Four cylinders are divided into groups (a) and (b), to which excessively rich and excessively lead air-fuel mixtures are supplied respectively from respective carburetors 2 and 2'. The exhaust gas enters through an exhaust gas port 12 into a thermal reactor 13 and is sufficiently mixed there by spiral vortex, and CO and HC in the exhaust gas produced from both the excessively rich and excessively lean air-fuel mixtures is completely combusted with residual oxygen. Since the air-fuel mixtures supplied to both the cylinder groups are excessively rich and excessively lean compared to the theoretical air-to-fuel ratio, the production of NO x  can be reduced. In addition, the ignition timings for both the cylinder groups are adjusted to minimize the generation of NO x .

Abstract: PURPOSE:To set brake timing and to reproduce a still picture at an optimum position by measuring pilot signals of a four-frequency tracking system and the rotational frequency of a capstan. CONSTITUTION:When a slow playback mode is commanded, the frequency of generation of a speed detection signal which is supplied from a control circuit 4 to an adder through a deceleration signal changeover switch S1 at specific timing and generate in a deceleration period is counted and denoted as FGST. If an edge of a head switching signal is detected after the run of a tape stops, ''1'' is added to the register in the controller 4 at every specific time, and when the instantaneous level of a tracking error signal decreases down to ''0'', the data in the register is read out to calculate the quantity FGS of tape transport. Then, said frequency of generation FGGEN is calculated from FGS-FGST as data for setting deceleration timing in step operation. When the step operation is entered, an acceleration signal is supplied to the adder 5 through S1. Then, when the frequency of generation of pulses as the speed detection signal attains to FGGEN, a deceleration command is generated and the tape stops.

Filed: 1990-04-26
Abstract: PURPOSE:To decrease the quantity of data to be stored and to attain the high speed conversion of data by storing previously each coefficient of a linear equation connecting the points showing the nonlinear output data into a memory as the output data against the input data. CONSTITUTION:A function curve showing the nonlinear output data against the input data is approximately by a straight line connecting points having each input equal to 2<n-1> (n = 1-N). Then (a) and (b) in an equation y = aX + b showing each straight line are previously stored in a memory as the output data against the input data. Then these data (a) and (b) are read out of the memory and the equation y = aX + b is calculated for output of the conversion data. Thus it is possible to reduce the conversion error and the number of data and also to attain the high speed conversion of data with a small memory capacity and in a small number of program steps.
