Title: Original reader
Inventor: TANIGAWA JUNICHI
IPC: H04N1/04
Filed: 1995-01-10
Abstract: PURPOSE: To prevent an original from entering on the lower side of a scale member in the case of positioning the original and also to easily detach the scale member by providing an elastic member on a gap obtained in the case the scale member abuts on a contact glass. CONSTITUTION: The elastic member 10 is provided on a surface where the first scale 3 and the second scale 4 abut on the contact glass 1, and is held and compressed between the scales 3 and 4, and the glass 1. By this compression, the member 10 is deformed to absorb the badness of planeness on the scales 3 and 4, and also to eliminate the gap formed between the scales 3 and 4, and the glass 1. By this constitution, the positioning of the original can be smoothly performed in the case the original is placed on the surface of the glass 1, and the end of the original abuts on the scales 3 and 4 so as to perform positioning.

Title: Switching power source circuit
Inventor: KANAMARU JIRO
IPC: H02M3/28
Filed: 1991-02-08
Abstract: PURPOSE:To prevent damage of a switching transistor by gradually increasing a current flowing to the transistor for a predetermined period immediately after a power source is turned ON, from a sufficiently lower value than a current at the time of a normal operation. CONSTITUTION:A point different from a conventional switching power source is a power source control circuit (SC) 7 having resistors R1, R2, a capacitor C1 and an operational amplifier 71. The SC 7 generates a power source voltage which is gradually raised by a switch SW1 immediately after a power source is turned ON. This voltage is supplied to a driving circuit 3. The circuit 3 outputs a driving signal Vda of a level responsive to the voltage. A current flowing to a switching transistor (ST) 4 is sufficiently lower than a current at the time of a normal operation immediately after a power source is turned ON to be a maximum, and increases upon lapse of a predetermined time. Accordingly, even if an output voltage Vout is 0V immediately after the power source is turned ON, the current flowing to the ST 4 is sufficiently smaller than the current at the time of the normal operation, and hence the ST 4 is not damaged.

Title: Controlling apparatus for knocking
Inventor: MARUYAMA HAJIME
IPC: F02P5/152
Filed: 1982-02-05
Abstract: PURPOSE:To enable to prevent occurrence of knocking, by connecting the output of a knock detecting circuit to corresponding integration circuits and connecting the output of an integration circuit storing therein the next ignited cylinder to an ignitor for controlling delay of the ignition timing respectively by a scanning switch in response to an ignition signal. CONSTITUTION:Providing that knocking is produced by a cylinder A and a knocking signal is applied to one terminal of an AND-gate, the output (a1) of the gate is rendered high by the signal of a scanning switch 5 and it is integrated and stored in an integration circuit 3A. Thus, if a knocking signal is produced at the time of ignition of cylinders B, C, D, it is integrated and stored in respective integration circuits 3B-3D via the scanning switch 5. On the other hand, if no knocking signal is produced, the outputs of the corresponding AND- gates become low. During the above operation, for instance, at the time of operation of the cylinder D, an analogue switch (a2) is turned ON simultaneously and a signal for delaying the ignition timing of the cylinder A to be ignited next is applied to an ignition timing delaying ignitor. Since, with such an arrangement, an optimum ignition timing for each cylinder can be obtained, it is enabled to prevent occurrence of knocking and to enhance the combustion efficiency.

After the fuel which flows from a fuel port 2a is injected from an injection valve to a combustion chamber through the discharge valve chamber 5 and a fuel pipe, the discharge of the fuel is finished and the 1st valve 62 is shut. Then, the fuel on the side of the discharge valve chamber 5 flows from the throttle hole 69 to the expansion chamber 70 and the 2nd valve 66 opens to allow the fuel to flow into a plunger chamber 4. At this time, the sudden fluctuation of pressure in the discharge valve chamber 5 is absorbed. Thus, the remaining pressure in the injection system is controlled constant and negative pressure is prevented from generating.

Title: Color printer
Inventor: TSUJI TAKANORI
IPC: B41J35/16
Filed: 1983-02-07
Abstract: PURPOSE:To discern colors with high reliability and high economical advantage by simple constitution in which a magnetic printing zone is provided in the color boundary of a multi-color film ribbon and detection of colors is made by a magnetic sensor. CONSTITUTION:A multi-color film 5 moves in the direction of arrow and passes by the front of a Hall element 7. In this case, according to the magnetic printing zone of the multi-color film 5, signals from the Hall element 7 are sent out one time in the case of Y, two times in the case of M and three times in the case of C. Output from the hall element 7 is amplified in a differential amplifier 8 and sent out to an output terminal S. Since no magnetism is contained in the color film, the output of the output terminal S is usually L-level signal. When the magnetic printing zone is passed, a voltage is generated in the Hall element 7, and H-level signal is output from the output terminal S of the differential amplifier. By judging the H-level signal and the L-level signal by a micro processor, for example, Y, M and C can be exactly discerned.

Abstract: PURPOSE:To maintain quantity of ejection of toner or ink at a constant value and to form an image stable for a long time by providing a control device that controls ejection of particles by activating a magnetic body and a power source device which apply magnetic field perpendicular to the direction of ejection of the particle and an electric current. CONSTITUTION:Since an electric current flows through toner 1 and a magnetic field B is applied perpendicular thereto, the toner 1 on the tip of a supplying nozzle 12 reaches to a nozzle 2 therefrom. After that, when the supply voltage between electrodes 15a, 15b is turned off, the force applied to the second toner 1 is eliminated and the toner 1 is stopped by a friction with the nozzle and a slant of the nozzle. Consequently, the toner 1 that reached to the nozzle 2 has an electric current I by the supply voltage between electrodes 9a, 9b and it is accelerated toward the tip of the nozzle 2 to be ejected to a recording medium 6 therefrom. At this time, the toner 1 is gelled by the heat due to the current, thereby the toner is taken the heat out and harden when sticking to the recording medium 6. Thus, an image is formed in accordance with a print signal.
