Title: Exciting power supply circuit of electromagnetic flow meter
Inventor: KOBAYASHI YUKIO
IPC: H01F7/18
Filed: 1979-03-06
Abstract: PURPOSE: To not only improve rise of an exciting current but also lower the voltage applied to a control transistor at a constant-current operation time, by using two exciting power sources and two control transistors in the exciting power supply circuit which supplies a square wave-form exciting current to an exciting coil.  
     CONSTITUTION: Exciting power source E 1  is connected to exciting coil L through transistor (Tr) Q 11  and diode D 3 , and exciting power source E 2  is connected to exciting coil L through TrQ 12  and diode D 4 . Output TrQ 2  of constant current circuit CC is connected to the bases of TrQ 11  and Q 12  through diode D 2  and Zener diode D 2 . At the rise of exciting current I, the output of differential amplifier A 1  is large, and TrQ 2  becomes a saturation state, and D 2  and D z  are turned on and TrQ 11  and TrQ 12  are turned on because the collector potential is low, and the voltage of the sum of power sources E 1  and E 2  is applied to coil L. Meanwhile, when exciting current I reaches set value I o , TrO 12  is cut off, and therefore, a current is flowed to only TrQ 11 , and the exciting current is supplied from power source E 1  to coil L.

Title: Forming press die for corrugated sheet
Inventor: TOYODA TETSUO
IPC: B21D13/02
Filed: 1987-02-06
Abstract: PURPOSE:To form a corrugated sheet by one stage without the need for a feeding stage and to make the equipment compact by inserting a thin plate stock between the opposing faces of the upper die base and lower die base on which freely turning roll shafts are arranged in parallel plurally respectively and approaching and separating each other. CONSTITUTION:Roll shafts 10 and 11 are projected from the opposed faces of an upper die base 7 and lower die base 8 respectively and arranged freely turnably at a specific pitch in parallel. A thin plate stock 9 is placed by inserting between the upper and lower roll shafts 10, 11 separated by opposing to approach the upper die base 7 and lower die base 8 by a driving mechanism. With this approaching, the thin plate stock 9 is gradually pulled to the center side at its both sides and meanwhile the roll shafts 10, 11 are turned, as occasions demand, in arrow mark directions respectively. The uneven working for the thin plate stock 9 is thus progressed to form currugated sheet by one time process and yet without the need for feeding.

Title: Frame ring for supporting glass plane in the device for bending and tempering
Inventor: TSUJI HIROSHI
IPC: C03B27/044
Filed: 1981-02-26
Abstract: PURPOSE: A glass plate taken out of the furnace is supported with the outer ring covered with a heat-insulating material and the ring is switched to the inner ring with comb-like teeth, when it is tempered by cooling, to produce a glass plate uniformly tempered and free from marks on the surface.  
     CONSTITUTION: When a glass plate heated in the furnace is received with a supporting frame, bended and tempered by rapid cooling, it is supported with the outer ring 1 covered with a heat insulation material such as asbestos, while it is melted, in order to keep the plate mark-free. The glass plate is bended with its own weight, formed by the air-foam methed and goes to the tempering device as being supported with the outer ring 1. When the glass plate is cooled and  becomes resistant to marking, the shaft 8 is operated to put out the inner ring 2 through lever 9 to support the glass plate, thereby the glass plate is subjected to tempering by rapid cooling. The tooth tops are made flat at the supporting part of the inner ring 2 and a metal net is set to increase its thermal conductivity so that no stress remains on the glass surface, when rapidly cooled.

Title: Driving method of induction motor
Inventor: SETO MAKOTO
IPC: H02P21/04
Filed: 1984-02-13
Abstract: PURPOSE:To obtain the prescribed torque at a low speed time by calculating a voltage command on the basis of a rated circuit constant of an induction motor, a slip frequency command and an inverter frequency command in accordance with a theoretical equation. CONSTITUTION:The first function generator 51 receives a slip frequency command omegas and an inverter frequency command (omega), and calculates and outputs a voltage component Vd parallel to the direction of the exciting branch current Ie of an induction motor 30 and a voltage component Vq parallel to the direction of a torque branch current Ir. The second function generator 52 calculates a voltage command Vm from the components Vd, Vq and outputs a PWM modulator 34. Thus, the primary terminal voltage of the motor 30 varies so that the current Ir becomes proportional to the slip frequency command omegas, and the torque corresponding to the operating condition is obtained.

Title: Carburetor for internal-combustion engine
Inventor: KITAMURA SHIYUUICHI
IPC: F02M7/20
Filed: 1982-02-20
Abstract: PURPOSE:To improve the specific fuel consumption as well as starting characteristics and exhaust gas characteristics, by accelerating atomization of the  fuel through an intake high-speed air stream fed out of a pump by pressure. CONSTITUTION:Intake air fed out of a pump 20 by pressure is strongly spouted out of a nozzle 15 together with fuel by way of a pump discharge passage 19 and a fuel efflux passage 18. The pressure acting on a contact part 11 where the fuel from a fuel jet 10 makes contact with the intake air is equal to that in the fuel efflux passage 18 while this pressure is also led to a lever chamber 8 and a float device 17 so that a difference in the pressure between the inlet part of the fuel jet 10 and the contact part 11 is kept constant at all times. Likewise, since the effective sectional area of the fuel jet 10 is made up so as to vary according  to the quantity of intake air flowing into an intake passage 1 in a carburetor, a proper mixture ratio required by the engine can be secured.

Title: Device for reproducing digital signal
Inventor: UMEZAWA MASARU
IPC: G11B7/00
Filed: 1993-02-16
Abstract: PURPOSE:To accurately make reproduction by detecting a synchronization short pulse signal with an inversion interval shorter than a prescribed time from the synchronization binary signal of a read signal and inverting and correcting the synchronization binary signal in a close side to sampling times of front and rear of a short pulse binary signal before synchronization of the signal. CONSTITUTION:The read signal is threshold processed by a comparator 41, and is synchronized with the sampling time(ST) of a clock signal by a data correction circuit 45 to output the synchronization binary signal SA successively. At this time, by a run length detection circuit 46, the short pulse binary signal SB with the inversion interval shorter than a prescribed time so as to disturb a run length limit among the signal SA is detected. By edge and front/rear timing detection and comparator circuits 48, 49, a time difference between the STs immediately before/after generating the signal SB and the front/rear edges of the binary signal SC before synchronization are obtained. By the circuit 49, the binary signal synchronized with the close side to the ST of the signal SC is made an error from the time difference, and an inversion signal is sent to the circuit 45, and the binary signal is corrected. Thus, the accuracy of reproducing is improved.

The ammonium chloride alphaformed by the reaction of ammonia with hydrogen chloride is introduced into the agglomerate of the fine alkaline particle gamma, and sublimed to form cavities. Consequently, the agglomerate is made porous. The latent heat of the ammonium chloride alpha is taken up as the vaporization heat of the liq. chemical, hence the ammonium chloride is solidified, and the solid is fixed and adsorbed on the surface of the bag filter 24. The unreacted fine alkaline particle gamma reacts with the solid, and ammonia is regenerated.
