Title: Picture signal processing circuit
Inventor: KAMIJIYOU EIJI
IPC: G06K9/38
Filed: 1983-07-22
Abstract: PURPOSE:To perform noise elimination processing to reduce the number of data by selecting and outputting a picture signal made binary simply if a resolution due to a scanner is high but selecting and outputting a picture signal, which is made binary with space filter processing, if the resolution is low. CONSTITUTION:The first means which makes the picture signal of an original, which is read by a scanner and is quantized to multilevels by an AD converter 1, binary after subjecting to the space filter processing and the second means which makes said picture signal binary simply are provided. When a switching signal SW of the read resolution of the original by the scanner attains to high level, the picture signal made binary by a binarizing circuit 9 is outputted selectively to the outside as a DBS. When the switching signal SW is reduced to low level, the picture signal obtained by processing latch contents through an inverter is outputted selectively to the outside as the DBS.

Title: Ground detector for motor protection relay
Inventor: MORIGUCHI YASUAKI
IPC: H02H7/09
Filed: 1987-05-29
Abstract: PURPOSE:To eliminate unnecessary function of protection relay due to surge current of motor, by connecting a resistor in parallel with a ground detection element of relay, thereby suppressing saturation of current transformer. CONSTITUTION:Upon throw-in of a circuit breaker 2, a motor 4 is started and starting current containing D.C. component flows through a motor feeder 8, thus accumulating flux produced by D.C. component in a current transformer 3. When a resistor 6 is connected in parallel with a fault detecting element in relay 5, apparent impedance of the fault detection element in the relay 5 decreases. Consequently, flux to be accumulated in the current transformer 3 is reduced so as to suppress saturation of the current transformer 3. Amount of flux phi to be accumulated in the current transformer 3 is represented by a formula shown on the drawing, and saturation can be suppressed through lowering of secondary load of the current transformer 3. Since sinusoidal current flows through the secondary of the current transformer 3, unnecessary function of relay 5 can be prevented.

By this method, a parent material for optical fiber having no fluctuation of outside diameter is obtd.

Title: Digit shifting device and floating point arithmetic unit
Inventor: YAMADA KENJI
IPC: G06F7/485
Filed: 1990-05-25
Abstract: PURPOSE:To shift a digit at high speed by providing plural multiplexers constitut ing a barrel shifter in such a way that the lower multiplexer to which a bit or a bit string on a low-order side in the output of an adder-subtracter is pro vided to the more preceding stage. CONSTITUTION:The lower bit with small delay time in the outputs of the adder- subtracter 1 is inputted to the multiplexer to the more preceding stage of the barrel shifter 11. When the output of the highest bit of a shift value from the adder-subtracter 1 is decided, the input signal of the multiplexer in the final stage of the barrel shifter 11 is decided. Then, output is decided after delay time passes in the multiplexer in the final stage of the barrel shifter 11 after the output of the highest bit in the adder-subtracter 1 is decided. Consequently, the delay time when the output of the barrel shifter 11 is decided becomes the sum of the delay time required for the decision of the highest bit of the shift value from the adder-subtracter 1 and the delay time of the multiplexer in the final stage of the barrelel shifter. Thus, processing speed improves.

IPC: G03G15/08
Filed: 1983-07-27
Abstract: PURPOSE:To prevent thoroughly intrusion of iron powder and to improve durability by providing a pair of annular magnets so as to sandwich a bearing of a circular side plate of a blender in such a way that the same poles face each other. CONSTITUTION:A blender 2 rotates in a toner bottle 1 and agitates a developer by fins 11 of connecting bars 12, 12'. Annular magnets 3 are adhered to both sides of the disc 10 at the end of the blender 2 by using double-coated tapes or adhesive agents having moisture absorptive curability in such a way that the N poles face each other on the inside and outside. The magnets 3 are spaced at 2mm. from a shaft 9. Iron powder is magnetized around the magnets 3 and the iron powder intruding into the space between the magnets and the shaft 9 is also magnetized on the inside circumferential surfaces of the magnets 3 and is therefore prevented from intruding into the space between the bearing part 4 of the blender 2 and the shaft 9. The deveseal (the iron powder attracted to the magnet) 5 between the magnets 3 and the shaft 9 acts also as a seal to prevent intrusion of the iron powder into the bearing part 4 and the deveseal 5 is prevented by the repulsive force of the magnets from entering the inside of the bearing hole.

Title: Electronic timepiece
Inventor: TAKAYAMA MASAYUKI
IPC: G04G19/00
Filed: 1982-08-04
Abstract: PURPOSE:To obtain a high-reliability electronic timepiece which eliminaties the need to replace a battery by using a capacitor and a solar battery as a power source, and charging the capacitor and operating an IC and a time display means which process time information. CONSTITUTION:The capacitor 12 drives the timer IC13. When light is made incident to the solar battery 11, the capacitor is charged with the generated current from the battery 1.The time display part 14 consists of a light-crystal panel or a hand display based upon motor drive. An excessive charging preventing circuit 15 is switched when the IC13 detects the terminal voltage across the capacitor 12 rising above the dielectric strength of the capacitor 11 during the charging of the battery 11, short-circuiting the battery 11. A reverse current preventing diode 16 prevents a current flowing from the capacitor 12 when no light is made incident to the battery 11. Thus, the capacitor which operates by physical action is used as the timepiece power source to obtain the electronic timepiece which eliminates the need for battery replacement completely.

Inventor: NODERA HISATOSHI
IPC: H03K17/72
Filed: 1977-11-11
Abstract: PURPOSE:To prevent the brightness of a luminescent diode from fluctuating when the voltage of power flucturates, by adding a transistor to a circuit consisting of a constant voltage diode and two silicon controlled rectifiers controlled through a sensor circuit. CONSTITUTION:The transistor 24 is turned on or off by the action of the sensor circuit 1 such as a proximity switch to control the silicon controlled rectifiers 22, 23. A diode 32 is connected between the cathode of the constant voltage diode and the node of a resistor 26 with a capacitor 29. Current is kept by the diode 32 from flowing thorugh the resistor 26. Thereby, the leaking current during the turn-off of the silicon controlled rectifier 22 is reduced. A transistor 35 is coupled between the gate and cathode of the silicon controlled rectifier 23. Therefore, a low gate current is sufficient to trigger the silicon controlled rectifier 23. Even if the power voltage fluctuates, stable phase control is perforemd. Thereby, the fluctuation of the brightness of the luminescent diode 34 is prevented.
