Title: Octal phase psk receiver
Inventor: HODOHARA KIYOAKI
IPC: H04L27/22
Filed: 1989-09-20
Abstract: PURPOSE:To attain error correction for each series by applying the calculation of phase shift of a phase corresponding to sets of signals inputted to 3 series of computing elements by 0 or pi/4 to the sets of the signals and controlling the phase shift in response to the result of calculation. CONSTITUTION:The receiver is provided with a phase shift means 58 in which a phase corresponding to sets of signals inputted to 3 series of computing elements 54 is shifted by 0 or pi/4 and with a phase shift control means 59 controlling the phase shift in the phase shift means 58 in response to the result of calculation of the computing elements 54. Thus, a value not 0 is consecutive as the result of syndrome calculation when the phase shift is an odd number of multiple of pi/4. In this case the phase shift of the phase shift means 58 is changed by pi/4 or -pi/4 by the action of the phase shift control means 59. Thus, the phase deviation is an even number of multiple of pi/4 and normal error correction is attained.

Title: Optical reception circuit
Inventor: KONO TOSHIBUMI
IPC: H04B10/69
Filed: 1985-10-29
Abstract: PURPOSE:To expand the dynamic range by providing a mean value output circuit outputting a time means value of an output of a current/voltage conversion circuit and an impedance conversion circuit so as to lower the timewise means value of an amplification circuit. CONSTITUTION:An output of a photodiode 10 is inputted to a non-inverting input of an operational amplifier 31 constituting an amplifier circuit 30 via a current/voltage conversion circuit 20 and an output of a mean value output circuit 60 is inputted to the inverting input via an impedance conversion circuit 70. While no light is made incident, a voltage inputted to the non-inverting input of the amplifier 31 is a reference voltage Vref and its output voltage is lower than the voltage inputted to the inverting input. When the light is made incident, the voltage inputted to the non-inverting input of the amplifier 31 is higher than the voltage inputted to the inverting input and the output voltage is higher than the voltage inputted to the inverting input. Thus, the timewise means value of the output of the circuit 30 is lowered and the dynamic range of the circuit 30 is expanded.

Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To maintain picture quality constant by varying the conditions of processes while returning a recycled toner to a fresh toner and to avoid increase in size of a machine main body. SOLUTION: An electrostatic latent image is formed on the surface of a latent image carrier 1 by an exposure means which emits light according to image data. A high-density, high-viscosity liquid developer is applied in the form of a thin layer to the surface of a developer carrier 41 and brought into contact with the latent image carrier 1 to develop the electrostatic latent image. The liquid developer remaining on the developer carrier 41 after developing process and on the latent image carrier 1 after transfer process is recycled into a recycling chamber 4B, where it is mixed with a starting agent and supplied to a developer supply chamber 4A. The developer in the developer supply chamber 4A is applied in a certain layer thickness to the developer carrier 41 by a developer application roller 42.  In using the liquid developer thus recycled, the linear velocity of processes is varied to keep an image constant.

Abstract: PURPOSE:To prevent the back flow of molten resin into a runner upon compression molding and manufacture the molded form of high quality, by a method wherein the gate of a mold is blockaded by the sliding surface of a runner block to intercept a cavity from the runner upon finishing the injection filling. CONSTITUTION:After finishing the injection filling of molten resin, an actuator 50 is operated to slide a runner block 40 leftward along the recess 21 of a movable mold 20. The gate connecting ports 42a, 42b of a runner 42 and a spool connecting port 42c of the same are blockaded by the inner surface 21a of the recess 21 of the movable mold 20.

Subsequently, the molten resin, filled into the cavities 30a, 30b of the title mold, is compressed. In compression process, respective gates 31a, 31b are blockaded by the sliding surface 41d of the runner block 40, therefore, molten resin will never flow back from the cavities 30a, 30b into the runner 42.

IPC: F22B37/00
Filed: 1988-09-28
Abstract: PURPOSE:To remove impurity mixed in steam through a simple and easy means and to hold the function and to improve durability by a method wherein an expanded incinerating part is located in a steam conveyance passage, and impurity, e.g. refuse, in steam is incinerated by heat from the outside for separation. CONSTITUTION:When impurity, e.g. refuse, an iron content, is mixed in water, the impurity heated by a heater 2 together with water is deposited to produce a scale, which flows in an incinerating part 15 in a state to be accompanied by steam. Since the incinerating part 15 is expanded compared with a steam conveyance part 12, a velocity of flow is reduced thereat, and an impurity component 20 is settled and adhered to the inner surface 21 of the incinerating part 15. Beside, since the incinerating part 15 is heated by an exhaust heat guided by a heat flow guide 19 and flowing in the direction of an arrow mark A, and the adhered impurity component 20 is incinerated, only clean steam is conveyed in the direction of an arrow mar B, and the impurity component 20 is prevented from adhering to the inner surface of a piping and a seal sur face. Further, steam is reheated by the incinerating part 15 to produce further dry steam, and the efficiencies of heating and bath, etc., are improved.
