Title: Control device for image density of copying machine
Inventor: KOUZU MAKOTO
IPC: G03G15/00
Filed: 1979-10-23
Abstract: PURPOSE:To improve the performance of image density control, by constituting the image density control device so that the influence of characteristic fluctuation of the developer based on environmental change and so on may be prevented, in respect to control of the image density. CONSTITUTION:Octal counter CT3 is reset by toner supply command signal St and is counted up by detection synchronizing signal Sd. Decoder DEC3 issues the high- level output from AND gate 44 when the count value of counter CT3 is 7, and this output is sent as toner supply command signal St or OR gate 46 through AND gate 45. Therefore, the circuit consisting of counter CT3, decoder DEC3, and AND gate 45 generates automatically toner supply command signal St to supplement the toner when 8 copies are obtained after issuance of the toner supply command signal. Thus, the toner density in the developer can be prevented from being lowered to a fixed value or less due to characteristic fluctuation of the developer.

IPC: H05H1/12
Filed: 1979-10-24
Abstract: PURPOSE:To omit a pure water device and the like and to miniaturize and simplify the magnetic- field generating apparatus by arbitrarily controlling the total impedance of the windings by using the conductors with no hollow part, cooling said apparatus by the cooling fluid in a nonmagnetic container, and insulating the windings and the fluid. CONSTITUTION:The fluid is introduced 2 into and exhausted from the annular hermetically sealed container 1 made of nonmagnetic stainless steel. Annular winding containers 4-6 made of the same material are coaxially arranged in said container 1 separately. Insulated and covered flat type conductors 7-9 are wound in the frame 4a-6a and the containers are formed by tightly sealing by outer plates 4b-6b. The lead wires of the windings are connected to terminals 17a- 19b provided on a connecting part 10. The windings 7-9 are connected in series. An epoxy resin  20 is impregnated into the container through the lead wire taking out part under the vacuum  state. A separating plate is provided between the winding containers and the hermetically sealed  container, thereby the path for the cooling fluid is formed. In this constitution, even though each  winding is a conductor with no hollow part, it is sufficiently cooled, the impedance can be arbitrarily set, and the windings and the cooling fluid are perfectly insulated. Therefore, a special  cooling device is not required.

Abstract: PROBLEM TO BE SOLVED: To supply a large power to a lamp-ignition driving apparatus, by using as a boosting circuit the resonance circuit composed of a resonance coil and resonance capacitor coupled to both the ends of a push-pull transformer. SOLUTION: A resonance transformer 6 uses the coil end of a wire L1 and the coil start of a wire L2 as inputs, and the resonance transformer 6 is connected with the drains of bidirectional switching transistors 3, 4. Using as its outputs the coil start of the wire L1 and the coil end of the wire L2, the resonance transformer 6 is connected with both the terminals of a resonance capacitor 7 and a plurality of front and rear surface inputs of a piezoelectric ceramic transformer 8.  Then, when the bidirectional switching transistor 3 is turned on and its drain voltage becomes rapidly at a low level, a voltage double the power supply voltage is generated in the drain of the bidirectional switching transistor 4, which is permitted to flow to GND through the winding L1 of the resonance transformer 6, the resonance capacitor 7, the winding L2 of the resonance transformer 6, and via the drain of the bidirectional switching transistor 3. As a result, the feed of a large power is made possible.

Title: Electronic timepiece
Inventor: KOYAMA HIROSHI
IPC: G04F10/00
Filed: 1981-09-01
Abstract: PURPOSE:To obtain an electronic timepiece that is operated by a simple program and consumes a little electric power by processing timing operation by means of interrupt action and stopping the CPU operation unless it is needed. CONSTITUTION:When interrupt signal of INT-0-INT-3 based on a program, operation starting signal CLK START and an output of a timer TIMER OUT are applied, the output of a NOR gate 24 that forms the FF of a clock generator is reversed to zero. With this reverse system clocks CLK-1-CLK-6 are output from a counter 18 of a clock generator with clock phi1 applied through a NOR gate 23, and time display and so on are made through a CPU. When this interrupt handling finished, the output of the gate 24 is reversed again by the stop signal CLK-STOP from a state control circuit and the counter 18 is reset and the output stops. Accordingly time measurement and so on are performed through the CPU only at the interrupt action, and the CPU is stopped when it is not needed, providing an electronic clock with a simple program and a little consumption of electric power.

Title: Switching power-supply circuit
Inventor: WATABE TOSHINORI
IPC: H01G9/048
Filed: 1991-06-10
Abstract: PURPOSE:To prevent an aluminum electrolytic capacitor from burning even when an overvoltage is applied by a method wherein a part near the winding core part of a capacitor element is formed as a empty winding part which is not provided with an anode foil. CONSTITUTION:In a capacitor element, an anode foil 1 and a cathode foil 2 are wound in a spiral shape via electrolytic paper sheets 3 and the element is fixed to the outer circumferential part of the wound element by using an element fixation tape 7. A lead terminal 4 for anode use is extracted form the anode foil 1, and a lead terminal 5 for cathode use is extracted from the cathode foil 2. A space 6 in a winding core part is a space which is formed when a winding core rod used to wind the element is pulled out after a winding operation has been finished. A part near the winding core part of the capacitor element is formed as an empty winding part which is not provided with the anode foil 1, and the empty winding part can absorb a force exerted on the winding core part and can prevent the anode foil 1 from being broken. Consequently, a short circuit between a cathode and an anode is prevented, and this prevents a capacitor from burning.
