Title: Method of reforming tar
Inventor: NAKAMA HIROSHI
IPC: C10C1/20
Filed: 1988-05-23
Abstract: PURPOSE:To improve reforming yield and attain reforming to a heavy tar having a grown aromaticity index by blowing at a predetermined temp. a low- temp. dry distillation tar produced in an apparatus by the use of an oxidizing gas. CONSTITUTION:In a continuous synthetic coke manufacturing process, a low- temp. dry distillation tar produced in an apparatus is blown at a temp. of from 150-500 deg.C by the use of an oxidizing agent, thereby reforming the tar to a pitch having an excellent hot load resistance. The extent of tar reforming and the reforming yield are affected by heating temp., the concn. and amt. of oxidizing gas and time. It is pref. that the oxygen concn. of the oxidizing gas be 5-100%, because when it is less than 5%, the tar is likely to have a low softening point and reforming rate is likely to be extremely low whilst reforming is effected. As long as the oxygen concn. is in the above range, desired tar reforming can be accomplished by blowing using, as the oxidizing gas, a gas obtd. by mixing combustion waste gas, etc., with air so as to attain effective utilization of the sensible heat of gas.

Title: Speaker diaphragm
Inventor: MOGI NORIO
IPC: H04R7/12
Filed: 1982-07-21
Abstract: PURPOSE:To smooth frequency characteristics of the high sound band to attain sufficient high band characteristic, by using a diaphragm which is so formed that the thickness is different toward the center of the diaphragm in each direction. CONSTITUTION:A voice coil bobbin 2 is connected to the center of a diaphragm 1, and a voice coil 3 is wound around this coil bobbin 2. Top parts theta1 and theta2 of the diaphragm 1 are different in directions of the longer diameter and the shorter diameter of the diaphragm 1; and with respect to the stiffness in cone top parts, the stiffness in the direction of the longer diameter is lower than that in the direction of the shorter diameter because of theta1>theta2 when the thickness of the diaphragm 1 is uniform. However, the diaphragm 1 is so formed that the thickness is increased gradually toward the inside circumference from the outside circumference in the direction of the longer diameter of the diaphragm. Since the stiffness of the cone top part in the direction of the longer diameter is higher by this form, the difference between this stiffness and the stiffness of the cone top part in the direction of the shorter diameter is reduced, and frequency characteristics of the high sound band are smoothed, and sufficient high band characteristics are attained.

Abstract: PURPOSE:To improve the latch-up by connecting a differentiating circuit changing the time constant in correspondence to the ambient lightness with the reversal input terminal of a differential amplifier in the photometry amplification circuit which amplifies the photoelectric current of a photodiode by the differential amplifier. CONSTITUTION:The photodiode 2 is connected between reversal and nonreversal input terminals 1a and 1b of a differential amplifier 1 and the photoelectric current of this photodiode 2 is amplified by the differntial amplifier 1.

By this, the latch-up of the output on the side of low illumination when a power source is closed can be eliminated in a short time, while, on the side of high illumination, the photometry can be performed immediately after the power source is  closed without being influenced by the differentiating circuit 7.

Title: Output method for signal synchronized with positioning action of positioning controller
Inventor: SUZUKI YASUYUKI
IPC: G05D3/00
Filed: 1988-05-24
Abstract: PURPOSE:To realize the output of the control signal in response to the arrival of a main control subject at a set position by comparing the address value of a detected position and that of the present position to transmit a signal pattern when the coincidence is obtained between both address values and transmitting the control signal of a secondary control subject synchronous with the arrival of the main control subject under a positioning action at the set position. CONSTITUTION:A shift arithmetic part 3 performs the positioning arithmetic of a main control subject with input of a positioning instruction, then outputs the positioning control signal consisting of the pulse trains corresponding to the speed, the acceleration and the shift value of the main control subject. At the same time, the part 3 outputs the address value of the present position of the main control subject. Then a comparison arithmetic part 9 compares the address value of the present position with the address value of a detected position which is previously set and recorded onto a detected position table 8. When the coincidence is obtained between both address values, a signal pattern corresponding to the address value of the detected position is outputted from a signal pattern table 10. At the same time, a signal output part 11 outputs the control signals of secondary control signals 12a-12c in response to said signal pattern. Thus the production of an exclusive sequence program can be omitted.
