Title: Steam heating apparatus
Inventor: FUJIMOTO SATORU
IPC: F24D7/00
Filed: 1987-07-01
Abstract: PURPOSE:To expand the range of a proper flow rate of a heat medium and to prevent the heat medium from being sucked during the stopping of operation, by interposing a check valve in a communicating tube to permit the flow of air from an air-liquid separator toward the exterior thereof and to block the flow of air from the exterior into the air-liquid separator. CONSTITUTION:A communicating tube 12 provided on the upper portion of an air-liquid separator 11 communicates between the interior of the air-liquid separator 11 and the exterior thereof. A check valve 13 interposed in said communicating tube 12 permits the flow of air from the interior of the air-liquid separator 11 toward the exterior thereof and blocks the flow of air from the exterior into the interior of the air-liquid separator 11. A heat medium introduced into a heat exchanger 5 with aid of a pump 6 is heated by a heating means 4, thereby turning the heat medium into steam. A steam volume within a circuit is increased due to generation of the steam, and excessive air is pushed out of the communicating tube 12 of the air-liquid separator 11. Since no air flows flom the exterior of the air-liquid separator 11 into the interior of the circuit by means of the actuation of the check valve 13, the decompressed condition of the internal pressure Pa/1 may be attained. When operation is stopped the the flow of air into the circuit is blocked by the actuation of the check valve 13, and consequently the internal pressure Pa/1 is retained without filling the circuit with the liquid heat medium.

Title: Formation of two-color image
Inventor: FUKUI KAZUYUKI
IPC: G03G15/01
Filed: 1986-07-12
Abstract: PURPOSE:To obtain a copy image wherein the black image part of an original is erased optionally and partially by controlling a light emitting means which emits light selectively and partially with a signal from an image area specifying means and exposing the entire surface except a specified area in an entire-surface exposing process. CONSTITUTION:Positive corona discharging is carried out by the tertiary scorotron charger 11 and then the entire surface except the specified area is exposed by an LED array 12. Namely, when a part corresponding to the specified area passes, the LED array 12 is turned off partially with the signal from the image area specifying means and when other parts pass, the LED array is turned on continuously. Therefore, positive charges at a black image corresponding part which are held between a dielectric layer (I) and a photoconductor layer (II) except in the specified area leak through a conductor base layer (III) except charges which are restrained by surface charges of the dielectric layer (I) when the electric resistance of the photoconductor layer (II) decreases, so that the surface potential corresponding to the black image area outside the specified area decreases to the negative side. Consequently, the two-color copy image is obtained while the black image part of the original is erased optionally and partially.

Title: Video signal reproducer
Inventor: TANAKA YUKIHIRO
IPC: G11B15/02
Filed: 1978-12-28
Abstract: PURPOSE: To ensure the effective reproduction by making ineffective the reproduction command of 3-fold velocity in case the fact that the recording velocity features the prescribed level is detected by the tape velocity detection circuit.  
     CONSTITUTION: Magnetic tape 1 is run toward the arrow mark in the fixed velocity via capstan 2 and pinch roller 3. At the same time, the control signal recorded on the track is reproduced through magnetic head 4 along with amplification 5 and also undergoes the waveform shaping to be then supplied to tape velocity detection circuit 6 and mono-multi 7 each. Here circuit 6 gives detection 6 whether the tape recording velocity is the 1st or 2nd velocity. Thus capstan 2 is driven with the 1st, 2nd and 3rd velocity by capstan servo circuit 8 to which the detection signal plus the reproduction order of the 3rd velocity are supplied. In this case, the reproduction command featuring the velocity of 3-fold velocity holding circuit 13 is made ineffective in case circuit 6 detect that the recording velocity is the 2nd velocity. In this way, the highly effective reproduction is ensured.

On the other hand, charged ink particles deviate from a fixed track and strike charge detection electrode 6 2  or 6 3 , and consequently the output of differential amplifiers 26 2  or 26 3  is held at "1" to increase or decrease the output voltage of level setting cirfuit 28, thereby varying the gain of level adjustment circuit 27. The output of circuit 27 is inputted to charge control circuit 20 to control the voltage of charge electrode 7.

Abstract: PURPOSE:To bring shoes in contact with a drum part smoothly so as to prevent a noise, by setting friction parts between a base plate which is rotationaly driven by a speed increaser, and a pair of shoes which are swingably supported on the said base plate as they can be expanded outward. CONSTITUTION:A braking unit 6 is formed of a base plate 6a and a pair of shoes 8 which are rotatably supported with shaft pins 6b of the said base plate 6a.

Title: Constant current circuit for integrated circuit
Inventor: KOJIMA HIROSHI
IPC: G05F3/26
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a constant current circuit without using many PNP transistors(TRs). SOLUTION: The base voltage of a 3rd TR 13 becomes voltage obtained by adding voltage Vbe between the base and emitter of TRs 2b, 10, 11 to the voltage drop of a resistor 12 due to a current flowing into 1st and 2nd current mirror circuits 1, 2. The emitter voltage of a 4th TR 14 bocomes voltage obtained by subtracting voltage Veb between the base and emitter of the 3rd and 4th TRs 13, 14 from the base voltage of the 3rd TR 13. Since the emitter voltage of the TR 14 is impressed to one end of a resistor 16 and the base- collector common voltage of a TR 15a is impressed to the other end, the same current as current flowing into the 1st and 2nd current mirror circuits 1, 2 is allowed to flow into a 3rd current mirror circuit 15 when the value of the resistor 16 is the same as that of the resistor 12.
