Title: Signal synthesizer
Inventor: SUZUKI YASUSHI
IPC: H04B7/08
Filed: 1992-02-25
Abstract: PURPOSE:To synthesize two signals whose frequency spectrum distribution is distributed symmetrically vertically with respect to a center frequency in an optimum state. CONSTITUTION:An endless phase shifter 7 changes the phase of an IF reception signal S2 in response to a control signal C from a control section 10. A phase comparator 6 detects the phase difference between two IF reception signals and sends phase difference data Dp. A frequency characteristic detecting section 8 detects the frequency spectrum distribution of a synthesis signal S3 synthesized by a synthesizer 3 and detects the symmetry of the spectrum distribution with respect to the center frequency to generate data Ds representing the symmetry. A data storage section 9 stores the phase difference data Dp and the data Ds representing the symmetry. A control section 10 changes at first by 0-360 deg.C the phase shift of the endless phase shifter 7 at a prescribed interval and stores the data Ds, Dp to the data storage section 9. Then the stored data are checked and when plural synchronization synthesizing points are present thereon a control signal is generated to a point in which the frequency spectrum distribution is most symmetrical.

Abstract: PROBLEM TO BE SOLVED: To ventilate the inside of an outer wall frame by arranging a large number of grooves on both surfaces of a backing plate main body, and arranging the step difference part to communicate with the grooves in the peripheral edge part on both surfaces of the backing plate main body. SOLUTION: The groove part 2 arranged on the obverse/reverse of a backing plate main body 1 is communicated with the step difference part 4 arranged in the obverse/ reverse peripheral edge part 3 of the plate 1. When the plate 1 is used as plywood for an outer wall structure, an air vent continuing by the groove 2 is formed on a contact plane of the plate 1 and an external facing material to the second floor from the first floor, and since the upper end of the plate 1 of the second floor is opened in an attic, an air flow is generated in the groove 2 to ventilate the inside of the external facing material. Next, in an outer wall filled with a heat insulating material, the outer wall inside is ventilated by the air vent formed in the contact plane of the groove 2, an upper frame, a lower frame and a head connector.  When the plate 1 is used as a floor structure, since the air vent is formed between the plate 1 and a finishing plate material by the groove 2, ventilation is performed to prevent a warp by moisture and reduction in durability. Therefore, heat entering a house can be cut off in the summer, and dew condensation can be prevented in the winter.

Title: Centrifugal casting of outside shell material in work roll for prestate of hot strip mill finishing
Inventor: NAKAGAWA YOSHIHIRO
IPC: B22D19/16
Filed: 1980-03-24
Abstract: PURPOSE: To intensify the directivity of crystal growth in outside shell material, improve carbide crystallization state and improve the performance of a roll by casting an adamite material for outside shell material under a gravity multiple applying force of a specific range in centrifugally casting said material.  
     CONSTITUTION: In producing a work roll to a centrifugally cast composite roll, it is cast in a range of gravity multiples 160W400G. At <160G gravity multiple, the directivity of primary crystal austenite dendrite growth weakens and carbide crystallizes in the form of network approximately from the roll surface. At >400G gravity multiple, carbide crystallization is about equal to the target value or is slightly poorer, but induced vibration is large to accelerate primary crystal crystallization effect or assists the parting of dendrite, resulting in slightly increased crystallization of carbide. In this case, a problem arises in mold strength in terms of actual operation, and there are restriction in economy and safety operation as well.

Title: Ignition timing control device in engine
Inventor: SAKURAI SHIGERU
IPC: F02P5/15
Filed: 1982-03-11
Abstract: PURPOSE:To prevent ignition timing from excessively advancing particularly upon  humidity rise under low load condition, by detecting the humidity of intake air and the  load of the engine so that the higher the humidity, the further the ignition timing is advanced, and by compensating the rate of the advance in accordance with the detected  value of the load. CONSTITUTION:A compensating rate generating circuit 17 reads out a compensating  rate for decreasing the value of spark retadation from a memory in accordance with an  output from a humidity sensor 15 and delivers the same to a compensating rate correcting circuit 18 when an engine is under the condition of, for example, high load and  the humidity of intake air is high. Further the above-mentioned compensating rate is  corrected to a value which represents a spark retardation value less than the spark retardation value indicated by the compensating rate obtained from the memory, in view  of a signal which is delivered from an intake air vacuum sensor 8 and indicates the  high load condition. Then, an arithmetic circuit 12 receives the corrected compensating  rate and carrys out arithmetic operation in accordance with an engine rotational speed  7 delivered from a spark retardation value control circuit 11 and the intake air vacuum  8 so that the thus obtained spark retardation value is decreased, and therefore, an igniter 13 is controlled by the output of the arithmetic circuit 12.

Abstract: PURPOSE:To measure the iron loss of the iron core of a rotary machine under conditions approximating those of the actual use, by detecting the temperature grade of the rise of temperature by a thermocouple attached to a stator when a rotor is rotated. CONSTITUTION:A coil 6 is excited through a ''Slidac  '', a cable 20, a brush 19, and a slip ring 7 by a prescribed power source. The output of a thermocouple 21 attached to the position for measurement of the iron loss of an iron core 15' is recorded on a recorder through an amplifier. The measuring method is as follows: (1) a shaft 4 is rotated in a prescribed speed, (2) the recorder is operated, (3) the coil is excited, (4) the rise of temperature of the iron core 15' is recorded on the recorder, (5) the tecorder is turned off after about 30 seconds, (6) excitation of the coil is stopped, (7) the rotation of the shaft 4 is stopped. A loss P is obtained by expression P=C.(DELTAT/DELTAt) where DELTAT, DELTAt, and C are the rise of temperature, the time, and the specific heat respectively. By this method, the iron loss at an optional point to which the thermocouple is attached is measured under conditions approximating those of the actual use.
