Title: Developer thin layer forming device
Inventor: HOSOI ATSUSHI
IPC: G03G15/08
Filed: 1985-10-24
Abstract: PURPOSE:To obtain good images without photographic fog by agitating a developer to be stuck to the surface of a developer carrier and forming a thin layer of the developer on the surface of the developer carrier reaching a developing part. CONSTITUTION:Magnetic particles 7 carried by rotation of a sleeve 3 are raised by the front end part of an elastic body blade 6 and are dropped near a magnetic pole 5 by the gravity and the magnetic force and are circulated in the direction of an arrow (c) repeatedly, and magnetic particles 7 are oscillated considerably near the magnetic pole 5. A developer 8 is agitated in a vessel 2 and is charged frictionally by rubbing against magnetic particles 7. When passing the contacting part between the elastic body blade 6 and the sleeve 3, the developer 8 is charged frictionally furthermore by rubbing against the surface of the sleeve 3 and the elastic body blade 6. The frictionally charged developer 8 passes the contacting part and is formed as a developer thin layer on the sleeve 3 and is carried to the developing part facing a photosensitive body 1 on the sleeve 3. Thus, good images are obtained stably.

Title: Optical recording head device
Inventor: MATSUBARA KEN
IPC: G02F1/03
Filed: 1990-09-05
Abstract: PURPOSE:To evade the influence of a spike type noise due to a charging and a discharging current which are generated when the power source for an optical shutter is turned ON and OFF and to prevent an IC from malfunctioning at the time of data transfer by providing a means which sends a data signal to an integrated circuit except when a driving pulse signal for driving an optical shutter array rises and falls. CONSTITUTION:Data are transferred into a shift register in series in synchronism with a clock CLK for image data transfer and watched with a latch strobe signal LS to send a pulse signal, thereby driving the optical shutter array 3. For example, a reference clock is used here for time control so that the data signal begins to be sent to the IC after a constant numbers of pulses are sent after the falling or rising start of the driving pulse signal. Consequently, the influence of the noise is evaded and the IC is prevented from malfunctioning at the time of the data transfer.

Filed: 1990-09-10
Abstract: PURPOSE:To amplify a test light from a testing light source by providing a stimulating light source in addition to the testing light source and allowing a stimulated light to irradiate a rare-earth group element added optical fiber connecting to the testing light source. CONSTITUTION:A test light whose wavelength is lambdat from a testing light source 6 is made incident on an erbium (Er) added optical fiber 9. On the other hand, a stimulated light whose wavelength is lambdap from an exciting light source 7 is made incident on the fiber 9 via a branching device 8 to excite the fiber. Thus, the testing light is amplified up to a prescribed intensity while being propagated through the fiber 9. The amplified testing light is distributed to four optical fibers (12-1)-(12-4) for relay via a 1X4 optical star coupler 10 (1 input and 4 outputs). The distributed testing light is fed to transmission fibers (2-1)-(2-4) via photocouplers (5-1)-(5-4). Thus, regardless of a single testing light source 6, the intensity of the test light distributed to the transmission fibers (2-1)-(2-4) is kept to a level required for the test or supervision of the transmission lines.

Abstract: PURPOSE:To stably process a photosensitive material by determining the necessary amount of low active supply developing liquid to be replenished next according to an arithmetic result based upon the preset supply amount and the replenishing amount calculated from the current operation time and stop time. CONSTITUTION:The value (target MDR value) of the replenishing amount of low active supply developing liquid to be replenished next is determined according to the arithmetic results based upon the preset replenishing value (temporary MDR value) of the preset replenishing amount and the value (real MDR value) of the replenishing amount found from the current operation time and stop time. Namely, the last real MDR is calculated and then the last actual replenishing amount is compared with the last target replenishing amount. The target MDR and real MDR are compared with each other and when the real MDR is larger than the target MDR, the difference l1 between the real MDR and target MDR and the difference l2 between the temporary MDR and target MDR are calculated. Then, those l1 and l2 are compared with each other and when l1>l2, the replenishing liquid is replenished by the difference (l1-l2).

IPC: G01C19/5642
Filed: 1991-09-18
Abstract: PURPOSE: To detect a Coriolis force with a simple structure by oscillating a bar-like body which exhibits a piezoelectric effect and has a rectangular cross section in a shear mode and detecting the electric signal corresponding to the inertial force. CONSTITUTION: A beam 1 is constituted of a rectangular plate 40 formed by using the crystal of a bismuth-germanium oxide so that the axes of the crystal can become the axes Ox, Oy, and Oz of the plate 40. The thickness of the plate 40 is made thicker at the central part 41 than that at end sections 42 and 43 and the plate 40 is supported by fixing both ends of the plate 40 to a substrate. When exciting electrodes 44 and 45 are formed on both surfaces of the central part 41 and a voltage V is applied across the electrodes 44 and 45 by connecting terminals T9 and T10 to the electrodes 44 and 45, an electric field is produced in the direction of the axis Oy and a shear deformation occurs in the plane yz of the plate 40.  When a torque Ω acts in the direction perpendicular to the plate 40 in such a state, an inertial force in the direction of the axis Ox generates an electric field in the direction of the axis Oz due to a shearing action and Coliolis effect 3 along the axis Oz. The intensity of the electric field in the direction Oz, namely, the acted turnover can be detected when the generated voltage is detected with detecting electrodes 46 and 47 and 48 and 49 which are arranged in point symmetry.

IPC: C10B39/02
Filed: 1986-10-06
Abstract: PURPOSE:To minimize the delay of pushing in a coke oven, by sending an instruction for emergency stop from a plurality of checkpoints according to the speed when the entry into a winding column wash inhibited in order to prevent collision. CONSTITUTION:Whether or not the entry is permitted is judged by a ground station 13 according to the state of a winding column. Only when the entry is permitted, and instruction for travel is output to a station 14 mounted on a fire-quenching car so that a bucket car or a fire-quenching car 3 is travelled towards the cooling column. The bucket car is passed through a first checkpoint F1. At that time, when the winding machine is out of order and a signal for inhibiting the entry has been input into the ground station 13, the actual speed is compared with the specified speed. When the actual seed is higher than the specified speed, a signal for emergency stop is output into the station 14 mounted on the fire-quenching car to stop the bucket car. When the entry is inhibited at a second checkpoint F2, a signal for emergency stop is output into the station 14 mounted on the car to stop the bucket even when the actual speed is lower than the specified speed.

Title: Transmission changeover circuit
Inventor: KAMIMURA TAKUZO
IPC: H04M1/50
Filed: 1985-10-25
Abstract: PURPOSE:To keep a required transmission level by switching the 1st or 2nd output circuit into the signal passing state or the signal interrupting state and outputting a dial signal from the 1st output circuit and a transmission signal from the 2nd output circuit selectively to prevent the attenuation of the dial signal. CONSTITUTION:The titled circuit consists of an amplifier 50 of the 1st output circuit sending a dial signal to a telephone line 4, an amplifier 52 of the 2nd output circuit sending a transmission signal to the telephone line via an equivalent resistor 42, a signal level detection circuit 56 detecting a dial signal at the pre-stage of the 1st output circuit and an operation changeover circuit 54 outputting selectively the dial signal from the 1st output circuit and the transmission signal from the 2nd output circuit. When the dial signal exists, the detection output brings the 1st output circuit to the signal passing state and the 2nd output circuit to the signal interrupting state and the dial signal is sent directly to the telephone line. Thus, the loss of the transmission level of the dial signal is prevented and a double transmission level is obtained in comparison with a conventional transmission level even at a low voltage.
