Title: Water level detecting device
Inventor: IMAMURA OSAMU
IPC: G01F23/26
Filed: 1978-02-06
Abstract: PURPOSE: To detect the water level correctly, by providing a first electrode to  detect the water level, and a second electrode to convert the change in the water  level up to an arbitray set water level different from the first electrode into an electrostatic capacity.  
     CONSTITUTION: The voltage transmitted to one end of each electrode, C xo , C y , C z , appears in each integrating part 3 after passing through detecting parts 5, re-spectively. The output from the water level detecting electrode C xo  after passing  through the integrating part 3 is inputted into the positive input terminal of a comparator 1, while the output from the reference voltage electrode C y  is inputted into  the negative input terminal of the comparator 1 through a water level setting part  6, and the output from the lowest water level electrode C z  is inputted into the reset  terminal of a latch 8 by way of a refill water setting part 7. And the output of the  comparator 1 is inputted into the set terminal of the latch 8. Thus, the intersection  between V cy1 , V cy2 , V cy3  showing the output of each set water level of high,  medium, and low level of the reference voltage electrode C y  and V cxo  showing the  output of the water level detecting electrode may be judged by the comparator 1.

Title: Facsimile device
Inventor: TSUDA SHIN
IPC: B65H26/00
Filed: 1982-01-29
Abstract: PURPOSE:To prevent previously the useless transmission, by inhibiting the reception of the rolled recording paper of a facsimile device at the receiving side in case said recording paper remains by an amount equivalent just to a sheet of original. CONSTITUTION:The output of a phototransistor 5 serving as a photodetecting element is fed to comparators 7 and 8 respectively. The threshold voltage, i.e., the reference voltage level for operation of the comparator 7 is set at VREF1 that is intermediate voltage between Vp and Vm. While the threshold voltage of the comparator 8 is set at VREF2 that is intermediate between Vm and Ve. Therefore outputs 7a and 8a are not produced if the voltage Vp showing the presence of the recording paper is applied to the comparator 7. Then the comparator 7 delivers the output 7a showing that the recording paper equivalent just to a sheet of original is left when the voltage Vm showing that an end mark 6 is detected is applied.

Title: Swirl controlling device of internal-combustion engine
Inventor: KAMIMURA HITOSHI
IPC: F02B31/08
Filed: 1982-01-29
Abstract: PURPOSE:To improve the fuel consumption, exhaust emission and output simultaneously by a method wherein the area of an auxiliary suction air passage is controlled in accordance with detected air quantity to be supplied so as to form a most suitable swirl in response to the detected air quantity. CONSTITUTION:The second throttle valve 10 in an auxiliary suction air passage 9 is opened and closed in response to the signal from an air quantity sensor 13. During the running at low speed and light load, because the air quantity to be suplied is small, the second throttle valve 10 is fully closed. Accordingly, the suction air is given a high swirl. On the contrary, during the running at high speed and heaby load, the improvement of suction efficiency is more required than the intensification of swirl. The second throttle valve 10 is opened dependently of the air quantity. Because the direction of swirls formed in the main and auxiliary suction air passages 8 and 9 are contrived to be opposite to each other, when the throttle valve 10 is moved to open itself, the suction efficiency is improved, though the swirl produced by means of the main suction air passage 8 is weakened.

IPC: G02B6/36
Filed: 1986-01-24
Abstract: PURPOSE:To prevent an optical fiber from being projected from a ferrule by providing a constriction part between a tip part and a large diameter hole part and arranging the expanded part of the plastic optical fiber in the large diameter hole part. CONSTITUTION:A tapered hole 7c is formed on the leading end position of a fiber inserting hole 7b, the large diameter hole part 7d is formed on a near back position of the hole 7c by recessing the part to form a larger diameter as compared to other portions and the constriction part 7 is formed between the holes 7c and 7d. Even if external force in the projecting direction from the ferrule 7 is applied to the optical fiber 10, the projecting movement of the optical fiber 10 from the ferrule 7 due to the external force is regulated by abutting the expanded part 10a formed near the leading end part upon the constriction part 7e. Consequently, the optical fiber 10 can be prevented from being projected from the ferrule 7 due to the external force.

Title: Ignition control device for internal combustion engine
Inventor: IWATA TOSHIO
IPC: F02P3/045
Filed: 1986-01-21
Abstract: PURPOSE:To improve the transient responsiveness of an energizing time control at the time of a small closed circuit rate by outputting an energizing signal to an ignition coil by using either of two signals: a signal generated from the time for ignition through the time for an interior division point, and a signal generated from the time for the interior division through the time for ignition. CONSTITUTION:In a pre-ignition period, when a rate of closed circuits is small, and when the time for start of energizing is in the section H of the output signal from a wave form shaping circuit 2, as a CE logic circuit 19 outputs an L signal, no counting by No.2 counter 10 is actuated. At the time of output signals from the section H of the wave form shaping circuit 2, when the CE logic circuit 19 outputs an H signal, No.2 counter 10 is counted to zero thereby outputting a bolo signal. This makes the output from an AND gate 16 a value of H and an ignition device 17 energizes an ignition coil. In this case, if an ignition period is abruptly changed into a short one, the amount of change in the ignition period is reduced as much as the output signal of the wave form shaping circuit 2 is proportional to the section H thereby making small the reduction rate of the energizing time for the ignition coil.

Title: Submergible pump
Inventor: FUKUZAWA SOUICHI
IPC: F04D5/00
Filed: 1981-02-02
Abstract: PURPOSE:To prevent clogging of a submergible pump, by producing swirl of intake water flow at the intake system of the pump for separting sand contained in water by the function of centrifugal force, and thereby unnecessitating filters for separating sand from water. CONSTITUTION:When a motor 9 is set into rotation, well water containing sand is introduced from an inlet port 1 into a swirl chamber 12 and flows downward with swirl as shown by arrows in the drawing. During the above while, sand is separated from water by the function of centrifugal force produced by the swirl of water flow, so that sand swirls along the wall surface and is introduced into a sand caturing chamber 13. On the other hand, water at the central portion of the chamber 12, not containing sand, is imparted with energy by a runner 7 and ejected as pressure water onto the ground via an outlet passage 6 and an outlet pipe 10. Therefore, it is enabled to unnecessitate filters.
