Title: Frame synchronizing system
Inventor: KAMATA YOSHIKI
IPC: H04L7/08
Filed: 1984-03-02
Abstract: PURPOSE:To shorten the time of restoration of synchronism and to increase the number of auxiliary data bits by inserting a complementary code of a frame pulse to a fixed position of a block including the frame pulse. CONSTITUTION:It is noticed that a bit -F1 is the complementary code of a bit F1, and received data and data obtained by delaying this data through an 8-bit delay circuit 3 by 8 bits are supplied to a comparing circuit 4. The comparing circuit 4 compares the input time of a frame synchronizing signal with the start bit of received data and the start bit of 8-bit delay received data, and synchronism is acquired if these start bits are F1 and -F1 or F2 and -F2 at the frame synchronizing signal input time. If synchronism is not acquired, a signal is sent to a frame synchronizing signal generating circuit 5, and the circuit 5 uses a clock to shift the frame synchronizing signal by one bit, and comparison is performed again with this frame synchronizing signal by the comparing circuit 4. This operation is repeated until frame synchronism is acquired. Thus, frame synchronism is acquired to transmit synchronizing pulses from an output terminal 6.

Title: Method of changing plate thickness under running of rolling mill
Inventor: SUMIHAMA TAKAHIRO
IPC: B21B37/24
Filed: 1983-03-11
Abstract: PURPOSE:To shorten a distance for changing plate thickness remarkably by calculating upper limit value of screw down speed corresponding to rolling load before changing plate thickness and estimated rolling load after changing the thickness by a specified approximation formula and controlling a hydraulic screw down device according to upper limit speed of small value. CONSTITUTION:Rolling load before changing and after changing plate thickness is calculated by an operator 11, and an upper limit value of screw down speed corresponding to these loads is calculated using a specified approximation formula that shows the relation between rolling load and upper limit of screw down speed, and the smaller value is made allowable screw down speed VS. Then, the time of changing and standard PS of rolling reduction are found basing on the speed VS in a change controlling device 10. When the passing distance of a rolling material 2 coincides with the set distance of change starting point, the standard PS is added to a position controlling device 4 of a hydraulic screw down device 3 by an in-rolling signal of a load gauge 7 and the signal of a pulse oscillator 8 of an electric motor 5. Thus, the plate thickness changing time is shortened and the changing distance is reduced remarkably, and the yield of production is improved sharply.

Title: Production of aluminum extruded flat tube for heat exchanger
Inventor: KAWASE HIROSHI
IPC: B23K1/00
Filed: 1989-02-20
Abstract: PURPOSE:To prevent the corrosion of the tubes from growing to deep pitting and to improve the life of the heat exchanger by thermally spraying an alloy having a specific compsn. on the surface of extruded tubes to cover the tubes. CONSTITUTION:The alloy contg. either one or two kinds of Sn and In within the range of 0.05 to 10wt.% the former and 0.05 to 10wt.% the latter and consists of the balance Zn is thermally sprayed to the surfaces of the tubes 3 extruded near the extrusion outlet of the tubes in hot or warm extrusion of the extruded flat tubes consisting of Al or Al alloy. The concn. of the Sn or In which is low in vapor pressure and hardly evaporates remains on the surface even if the concn. of the Zn on the surface layer is deceased by evaporation of the Zn when the heat exchanger is produced by using these tubes and by vacuum brazing. Thereby the layer of Sn or In becomes the sacrificed anode layer to prevent the corrosion of the tubes from growing to deep pitting.

Title: Double frequency band shared antenna
Inventor: KATAKI TAKASHI
IPC: H01Q5/00
Filed: 1981-03-19
Abstract: PURPOSE:To reduce the side lobe level at the S band, by forming a feeding element of a cross dipole antenna for a ground station that tracks a rocket, etc. and a linear conductor which functions as a reflector into a mesh which is >=half wavelength at the S band and <=half wavelength at the VHF band respectively. CONSTITUTION:For an S/VHF shared antenna, the electric wave sent from a primary radiator 1 of the S band is reflected by a secondary reflector 2 and a main reflector 1. A cross dipole antenna 4 which functions as a primary radiator of the VHF band is attached to the reflector 2, and a reflector 3 is shared by both S and VHF bands. A linear conductor 8 which is formed by the wire netting with a round section for example is used for the antenna 4. The mesh of the conductor 8 is set at >=half wavelength at the S band and at <=half wavelength at the VHF band respectively. As a result, the conductor 8 is substantially transparent to the electric wave of the S band and functions virtually as a conductor plate to the electric wave of the VHF band. Thus the side lobe level can be improved for a secondary radiation pattern of the S band.

Abstract: PURPOSE:To prevent the movement of an island, and to stabilize assembly by pressing and fixing the island hanging lead of a lead frame by a rigid material. CONSTITUTION:The island hanging leads 5 as two important positions fixing the islands 5 of the lead frame are held down by a rigid material section 8, and escapes 9 in case of the press of an elastic material are utilized and the variance of the thickness of lead sections is absorbed in other lead sections 6, thus applying pressure to all the leads. Slits are formed obliquely to the pipe of the rigid material section 8 in order to prevent the intrusion of the leads into the clearances of the slits. Accordingly, since the two important positions can be fixed by the rigid material, the island 4 is not moved, and assembly is stabilized.

Abstract: PURPOSE:To perform operation at the same speed with an actual communication circuit in a diagnostic lap by transferring a significant bit signal and lap data to a receiving circuit to be diagnosed by a communication processor every time the receiving circuit is scanned. CONSTITUTION:A diagnostic lap mode signal WRAP, bit service signal BSVC, etc., are applied to an FF7 at the circuit scanning part CS3 of the communication control processor CPP.

An FF6 samples the WRAP DATA by the signal STRB and outputs the result as receive data RD, which is transferred to the CPP together with the signal BSVC. The CCP collates transmission data SR with the data RD.
