Title: Redial processing system to same subscriber
Inventor: SHOJI NAOMI
IPC: H04M3/42
Filed: 1992-04-15
Abstract: PURPOSE:To attain smooth re-dialling processing with simple operation by allowing a starting section to transmit a line re-connection request signal and allowing a called party to inform redialing when the redialling request from a caller side subscriber is discriminated. CONSTITUTION:A re-dialling request monitor section 1a monitors a caller side subscriber 2 after the interruption of a speech line to discriminate whether or not there is a redialling request. Moreover, a signal starting section 1e transmits a line connecting request signal to a called side subscriber exchange 4 based on the redialling request from the subscriber 2. When interrupting of a speech line by the called side subscriber 3 is informed by the exchange 4, the monitor section 1a of the caller side subscriber exchange 1 monitors the subscriber 2 to discriminate the redialling request from the subscriber 2. The starting section 1e transmits the reconnecting request signal to connect the subscribers 2 and 3 to the exchange 4. Then since the exchange 4 informs re-dialling to the subscriber 3 based on the request signal, smooth re-dialling processing is implemented automatically with a simple operation of the caller and the convenience is enhanced.

Title: Treatment of water containing cyano-complex
Inventor: KATOU ISAMU
IPC: C02F1/78
Filed: 1982-06-03
Abstract: PURPOSE:To treat cyano-nickel complex and cyano-iron complex simultaneously and effectively by subjecting water contg. cyano-complex to an ozone treatment then adding a reducing agent and separating the precipitate formed in a specific pH region in the presence of copper ions. CONSTITUTION:Ozone of about >=5 times as much as total cyanogen is first added to raw water to decompose the free cyanogen and cyano-nickel complex in the raw water substantially completely; further, about 20-50% of cyano-iron complex is separated. The remaining cyano-iron complex is removed by the reaction with copper ions. Since the copper ions are made into the copper oxide of high order by the previous ozone treatment, a reducing agent is added thereto reduce the same. If the pH is adjusted to 4-11, the copper ions react with the cyano-iron complex simultaneously with the reduction and the compd. expressed by Cu2[Fe(CN)6] is generated as a precipitate. The precipitate is then subjected to a solid-liquid sepn.

Title: Semiconductor integrated circuit device
Inventor: SEKINE YASUSHI
IPC: H01L21/331
Filed: 1985-05-07
Abstract: PURPOSE:To improve the circuit characteristics of a circuit having an NPN transistor and a PNP transistor combined, by forming the NPN transistor as well as the PNP transistor into a transverse type. CONSTITUTION:In a vertical NPN transistor, the current amplification factor hFE is not decreased until collector current attains a considerably large value. In a transverse PNP transistor and a transverse NPN transistor, on the con trary, the hFE starts to decrease at a lowe collector current than the vertical NPN transistor. The transverse PNP and NPN transistors have hFE properties analogous to each other though the PNP is somewhat inferior in performance. Accordingly, if the transverse NPN transistor and the transverse PNP transistor are used to constitute a power supply circuit, these transistors can be matched with each other very well. Therefore, characteristics of the circuit as a whole are increased substantially.

IPC: H04B10/60
Filed: 1984-05-14
Abstract: PURPOSE:To apply binary-coding even to an optical signal minute in amplitude and to restore correctly the pulse width by providing a light receiving circuit having a wide dynamic range and less pulse distortion in which specific resistance values are used and capacitors of small capacitance only are employed so as to form a one-chip monolithic IC. CONSTITUTION:The titled circuit is formed as a one-chip integrated circuit except an externally mounted capacitor Cext. A voltage signal (b) is differentiated once so as to eliminate the DC component in the circuit. A signal (d) is obtained by retarding one of the signals and a differentiation signal (e) is obtained by applying differential amplification between the signal (d) and an original signal (c) in the differentiating circuit. The differentiating signal (e) is given to a base of a Q9, where the signal is subject to current amplification. A transistor (TR)Q41 connected to the emitter of the Q9 and a resistor R28 form a constant current circuit. The base voltage is given by R23 and R24. The level of the emitter (f) of the Q9 is lower than the level of the (e) by the base-emitter drop. In order to binary-code the signal (f), the mean value of the (f) is obtained and the (f) and the mean value of the (f) are amplified differentially. Thus, the dynamic range is widened and the problem of offset is eliminated.

Filed: 1980-07-15
Abstract: PURPOSE:To increase the usability of a memory, by combining a main bank memory of the address information which is stored in the 1st register with a subbank memory of the address information which is stored in the 2nd register. CONSTITUTION:Main bank memories B0-Bn are designated by addresses b0-bn that are set to a main bank register RB. Then a designated main bank memory is used in combination with a common bank memory D. In the same way, subbank memories C0-Cn are designated by addresses C1-Cn which are set to a subbank register RC. Then a designated subbank memory is used in combination with a common bank memory. The capacity of memories C1-Cn is set smaller than that of memories B0-Bn. Thus the capacity of a main bank memory is used for other purposes in case the capacity of a combination between the memory D and a sub- bank memory suffices.

Title: Air-conditioning equipment for vehicle
Inventor: HONMA ATSUSHI
IPC: F25B47/02
Filed: 1993-04-23
Abstract: PURPOSE:To obtain air-conditioning equipment for a vehicle which enables stable prevention of freezing and can be handled easily. CONSTITUTION:A pressure sensor 10 as a pressure detecting means for detecting a refrigerant pressure of a refrigerant circuit 1 is interposed between a motor- operated compressor 2 and an evaporator 4 being the low-pressure side of the refrigerant circuit 1. The pressure sensor 10 detects the refrigerant pressure on the low-pressure side of the refrigerant circuit 1 and outputs a pressure detection signal S3 to a controller 8. The controller 8 outputs a control signal S2 in accordance with the pressure detection signal S3 to an inverter 9. Based on a prescribed pressure threshold set to be higher than a freezing start pressure value at which freezing starts in the evaporator 4, the controller 8 controls the inverter 9 for the prescribed pressure threshold when a pressure value corresponding to the pressure detection signal S3 lowers below this prescribed pressure threshold, and therefore frosting is prevented without fail before the freezing in the evaporator 4.

IPC: F16C13/00
Filed: 1994-05-10
Abstract: PURPOSE:To obtain a roll which has a lower electrical etching effect on a photosensitive drum, chips a photosensitive material in a lesser amt. and is satisfactorily usable over a long period of time by forming a resistance control layer to the thickness smallest in the central part of an axial direction and gradually larger toward both ends, thereby forming this layer to an hourglass shape as a whole. CONSTITUTION:This electrostatic charging roll is composed by forming a conductive elastic material layer 2 on the outer peripheral surface of a core body l, forming the conductive resistance control layer 3 on its outer peripheral surface and further forming a protective layer 4 on its outer peripheral surface. The resistance control layer 3 is so formed that its thickness is smallest in the central part of the axial direction of the roll and is increased gradually larger toward both ends. The roll is thus formed to the hourglass shape as a whole. The resistance value at the ends of the electrostatic charging roll in contact with the ends of the photosensitive drum where the film thickness of the photosensitive material is small is high according to such constitution when the roll is actually used by pressing the roll to the photosensitive drum and, therefore, the photosensitive material is chipped in the smaller amt. at both ends.
