Title: Production of toner for electrophotography
Inventor: ITAYA HIDETAKA
IPC: G03G9/087
Filed: 1987-07-30
Abstract: PURPOSE:To improve the quality of an image and the moisture resistance of a toner by subjecting a polymerizable monomer to emulsion polymn. in the presence of a reactive surfactant to produce a binder and by using the binder. CONSTITUTION:A polymerizable monomer is subjected to emulsion polymn. in the presence of a reactive surfactant to product a binder. The surfactant provides polymn. sites to the monomer and is incorporated into the chain of the resulting polymer as a constituent of the polymer, the moisture resistance of a toner contg. the binder is improved and the density of an image is increased. When an anionic or cationic surfactant is used, the use of an electrostatic charge controller can be made unnecessary or reduced by half. A toner contg. no electrostatic charge controller can be arbitrarily colored.

Title: Optical thin film waveguide
Inventor: MIYAMOTO SUEHIRO
IPC: G02B6/12
Filed: 1985-08-30
Abstract: PURPOSE:To reduce the loss of connection without any mismatching of impedance when an optical waveguide is connected to an optical fiber by forming a core part by using pure quartz. CONSTITUTION:The core part 3 which guides light is formed of substantially pure quartz, e.g. fused quartz, synthetic quartz, optical glass, etc. The core part 3 made of the pure quartz is surrounded with a clad part 4 having a low refractive index on a substrate 5. When a quartz optical fiber 4 is connected to the core part 3, there is almost no difference in refractive index between the both, so there is no difference in impedance and the loss of the connection is reduced. Consequently, the transmission loss of the whole optical communication system is reduced.

Title: Monitor control system of power plant
Inventor: ETOU YASUSHI
IPC: H04Q9/00
Filed: 1981-12-01
Abstract: PURPOSE:To decrease the number of signal transmission lines and to avoid the incapability of the monitor control due to the congestion of information, etc., by providing independently a transmitter which transmits the control information and the monitor information between a centralized controller and a field device. CONSTITUTION:A centralized monitor controller 40 gives the monitor/control to a field device 60. For this purpose, the information which is transferred between the devices 40 and 60 directly or via a local controller 50 is divided into the information for monitor and that for control. The monitor information is transmitted via a monitor transmitter 83a containing a station 81a and a transmission line 82a; while the control information is transmitted via a control transmitter 83b containing a station 81b and a transmission line 82b. As a result, the number of signal lines connecting between the devices is decreased to realize a compact information transmitting means. Furthermore, if one of the two transmitters has a fault, the minimum necessary monitor/control is secured through the other nondefective transmitter. Thus the safety is ensured.

Inventor: KOBAYASHI TAKEHARU
IPC: B01D29/62
Filed: 1984-09-13
Abstract: PURPOSE:To simplify a mechanism and to automatically perform the backwashing of a filter membrane, by performing the backwashing of the filter membrane almost periodically by utilizing filtered water. CONSTITUTION:When water to be treated is filtered by a filter apparatus, filtered water passes through a drain pipe 33 and a cylinder part 45 to be stored in a fixed water tank 41. When the amount of the filtered water increases in the fixed water tank 41, a float ball 63 rises and a shaking valve body 61 is drawn up to open an outflow port 59 and the filtered water in the fixed water tank 41 is flowed into a movable water tank 67 from the outflow port 59. When the amount of the filtered water in the movable water tank 67 increases, the movable water tank 67 falls against a compression spring 71 and, with the falling of said tank 71, the piston lever 75 and piston 47 of a change-over valve mechanism 43 are fallen to allow the piston 47 to reach the state shown by an imaginary line and compressed air pushed the filtered water and, as a result, the filtered water is flowed backwardly. Whereupon, the filtered water passes through a filter membrane from a secondary side to a primary side along with air to wash off the residue on the surface of the filter membrane.

Title: Inclination processing circuit for data in memory
Inventor: OOYA KOUICHI
IPC: H04N1/387
Filed: 1981-12-02
Abstract: PURPOSE:To prevent exclusive occupation of an operation controlling part in the inclination processing, by updating the line address for every several bits when picture data, which is read out from a picture memory while updating the line address for every several bits, is written in the picture memory. CONSTITUTION:Picture data outputted from a photoelectric converting part is stored in a picture memory 2. An operation controlling part 1 calculates the inclination of an original on a basis of this data. When an inputted original 9 is inclined slightly from a reference line 10, a line address LA is updated in 20-byte units in accordance with the inclination to read out data. The operation controlling part determines the right shift or the left shift of one-line data of the picture memory 2 on a basis of the calculated inclination and calculates the  number of bits to be shifted for the purpose of preventing the distortion. A line  address output circuit 3 updates the line address each time a required number of bits of data in the picture memory 2 is read out.

Title: Frequency synthesizer system
Inventor: SASAKI YUTAKA
IPC: H03L7/08
Filed: 1987-07-31
Abstract: PURPOSE:To quickly transmit a response signal to an incoming signal even if a frequency synthesizer for transmission signal is intermittently operated during waiting, by providing a switch between a charge pump and a low-pass filter. CONSTITUTION:The intermitted operation that a switch 3 is turned on only for a time t2 is repeated with a period t1 (t1 is 2 sec. and t2 is 50msec.). A switch 43 is turned on after turning-on of the switch 3 and is turned off just before turning-off of the switch 3. In this case, a low-pass filter 44 is constituted to include a large-capacity capacitor, and the load of the filter 44 is the varactor capacitor diode of a VCO45 and its impedance is very high. As the result, the frequency of the transmission signal outputted from the VCO45 very approximates a normal frequency at the time of turning-on of the switch 3; and therefore, quick response to the incoming signal is possible even if the interruption frequency of a phase synchronizing loop is reduced.
