Title: Bit synchronization circuit
Inventor: ONODERA KIYOMITSU
IPC: H03L7/087
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a bit synchronization circuit, which can operate even at a fast bit rate, has no blind phase and can instantaneously secure the bit synchronization without using a multiphase clock and multiphase data by performing the comparison of amplitudes of output voltage between a 1st and 2nd phase comparison means to select a clock signal that is suitable for selecting a data signal. SOLUTION: Comparison of phases is carried out between a DATA-PRE and a (CLK/2-0) and a (CLK/2-π/2) respectively. When the amplitude of both- phase output of a phase comparator PCMP of the (CLK/2-π/2) is small, the DATA is identified by means of a fall of an external clock signal CLK. Meanwhile, the DATA is identified by means of a rise of the signal CLK, when the amplitude of both-phase output of the PCMP of the (CLK/2-0) is small. Thus, the data can always be identified at a point near the center of the input data, and accordingly identification errors can are extremely reduced. Thereby it is just required to input two outputs of the PCMC to an amplitude comparator ACMP, to select a CLK/2 of small amplitude and to select a clock that is corresponding to the CLK/2.

Filed: 1990-06-25
Abstract: PURPOSE:To attain diversity reception not requiring each processing for level comparison as to remaining antennas and equivalent to the use of lots of antennas with less processing by limiting pair antennas for final level comparison depending on a current position of a rolling stock in advance. CONSTITUTION:Switches SW1, SW2 are used to select one of 2nd left right antennas R2, L2 and switches SW3, SW4 are used to select one of 1st left right antennas R1, L1.

After the signal is amplified by an amplifier 24, the result is demodulated to a low frequency audio signal by a demodulator 25. Simultaneously, a level detector 26 detects a level of an intermediate frequency signal to discriminate the received electric field strength and a multi-path detector 27 discriminate multi-path noise.

IPC: F16J1/22
Filed: 1978-12-19
Abstract: PURPOSE: To eliminate metallic contact of a piston by putting a wear-proof member on a sliding face between a spherical body and a shperical surface, and also to reduce the time required for machining by making the rough machining of the spherical body and shperical surface suficiently precise as finishing.  
     CONSTITUTION: The sliding face of a spherical body 3 is firmly covered with wear- proof material 14 such as resin and held on the bearing surface between the body 3 and a spherical surface 6. Thus a connecting rod 7 and a bearing rod 4 compose a spherical pair of juncture, having the wear-proof material 14 between them as an ideal sliding face, which requires no improved accuracy through finishing machining. In addition, the machining process can be simplified because it is enough to force an engaging unit 12 into a hole on a piston 2 until a positioning step 11 comes in touch with a touching surface 10.

Title: Manufacture of electric boiler
Inventor: IKUMA HIDEYUKI
IPC: F24H1/18
Filed: 1988-07-04
Abstract: PURPOSE:To improve the feed efficiency of steam by a method wherein, after a heating pipe is inserted through a hole formed in a lower pipe header and the upper end part of the heating pipe coincides with a hole formed in an upper pipe header, the heating pipe is connected to the upper and the lower pipe header by welding, and a boiler water flow passage is formed in a heating pipe part positioned in the lower pipe header. CONSTITUTION:Since, during heating of boiler water 30, the boiler water 30 in a heating pipe 5 is heated, the boiler water 30 in a steam generating part enters the heating pipe 5 through a boiler water flow passage 40a. Namely, the boiler water 30 in a lower pipe header 3 is at a normal temperature and the boiler water 30 enters the pipe 5 through the flow passage 40a of the pipe 5. In the pipe 5 in a lower pie header 3, when the boiler water 30 is heated in the pipe 5 by means of a heater 9 to a temperature lightly higher than an ordinary temperature, the boiler water rises within the pipe 5. In this case, the pipe 5 in the lower pipe header 3 prevents the occurrence of convection by means of a temperature difference in the boiler water 30 between the boiler water 30 inside the pipe 5 and the boiler water 30 outside the pipe 5 and therefore, a convection preventing part 5a performs its role. This constitution causes the rapid rise of the boiler 30 in the pipe 5 and causes the boiler water to produce steam in a short time for storage.
