Title: Ignition coil
Inventor: KATO KATSUHISA
IPC: H01F27/32
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an ignition coil having long service life by restraining the growth of a tree in a spool which is generated by discharge. SOLUTION: In this ignition coil, a primary spool 23 is arranged on the outer periphery of a secondary coil 21. The primary spool 23 uses PBT (polybutylene terephthalate) which has low melting viscosity and is superior in molding fluidity as a resin base material, and to the PBT, 5 wt.% of olefin rubber, 12.5 wt.% of glass fiber and 2.5 wt.% of silica are added, and the spool is formed. A primary coil 24 is formed by winding a winding in which PET (polyethylene terephthalate), silicone, wax, etc., are coated as separating member on the outer periphery of a wire, on the outer periphery of the primary spool 23. Since silica is added to the primary spool 23, the growth of a tree in the primary spool 23 is restrained, oven when discharge is generated between the secondary coil 21 of high potential and the primary coil 24 of low potential and corrosion is generated in the primary spool 23.

Title: Selective call radio receiver
Inventor: KUDO HIROSHI
IPC: H04B1/26
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To securely operate an AGC circuit without causing a drop of an input signal by detecting the electric field intensity of a received wave from an intermediate-frequency signal, performing voltage-current conversion of the electric field intensity detection signal, and inputting this output to the AGC control circuit. SOLUTION: A front end 10 converts a received signal into an intermediate frequency(IF) signal and the signal demodulated by a signal processing part 30 which demodulates the intermediate-frequency(IF) signal and detects the electric field intensity is decoded by a decoder 60. The signal processing part 30 detects the voltage amplitude of the intermediate-frequency(IF) signal varying with the electric field intensity of the antenna input and converts it to an electric field intensity detection voltage (VRSO) corresponding to the electric field intensity-to-DC voltage characteristics of the received wave. To the AGC circuit 20, the electric field intensity detection voltage is not connected directly, but a load current is supplied through a voltage-current converting circuit 50.  Consequently, the AGC control circuit 20 can obtains a load current without causing a drop of the electric field intensity detection voltage.

Title: Connecting structure for chalcogenide glass optical fiber and quartz based optical fiber and optical driving type optical controller using this connecting structure
Inventor: YUBE MASAO
IPC: G02F1/35
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to connect a chalcogenide glass optical fiber and quartz based glass optical fibers with low loss and low reflection by expanding the mode diameter of the first quartz fiber of the mode diameter approximately equal to the mode diameter of the small-diameter chalcogenide glass optical fiber to a tapered form so as to coincide with the mode diameter of the second fiber. SOLUTION: The chalcogenide glass optical fiber 43 and the quartz fiber 42 are formed nearly to the same core diameter and antireflection films 45, 46 are respectively formed on both. The two fibers 43, 42 are disposed to face each other to align their optical axes and are fixed to a guide 47 by using an adhesive 48. After the quartz fiber 42 and the quartz fiber 41 are fusion spliced, the quartz fiber 42 is heated to diffuse the germanium in the core, by which the core is worked to the taper shape 44 until its core diameter coincides nearly with the core diameter of the quartz fiber 41. As a result, the constitution of various kinds of the control optical switches of the low refractive index and low loss is made possible by using the chalcogenide glass optical fiber having high nonlinearity.

Title: Antenna tracking control circuit
Inventor: YASUKAWA NAOSHI
IPC: G01S3/44
Filed: 1987-02-25
Abstract: PURPOSE:To perform accurate step track operation at all times even when antenna use conditions are changed by adjusting an offset voltage automatically so that the level of an antenna received signal outputted by an amplifier is always within a certain constant range. CONSTITUTION:When the output voltage Vi of a summing amplifier 2 exceeds an upper-limit threshold value VB and the output level of a voltage comparing circuit 3 becomes 1, a control circuit 6 sets the output voltage of a multiplexer 7 to V11 which is one stage higher than a current value 0. Consequently, the offset output voltage to the summing amplifier 2 rises to VD=V11. At this time, the control circuit 6 operates to select the output of the multiplexer 7 so that the output voltage Vi is within the range between the lower-limit value VA of a voltage comparing circuit 4 and the upper-limit threshold value VB of a voltage comparing circuit 3.

Title: Circuit for correcting automatically picture at weak electric field
Inventor: NISHIKAWA TAKUSHI
IPC: H04N5/208
Filed: 1983-03-16
Abstract: PURPOSE:To automate adjustment of a picture at a weak electric field by decreasing a level of a contrast adjusting signal and a color density adjusting signal in response to a level difference when a voltage level of a gain control signal becomes higher than a prescribed voltage. CONSTITUTION:When a voltage level of a gain control signal on a signal line 1 is higher than a Zener voltage of a Zener diode ZD3, the ZD3 is conductive and a current flows to a base of a transistor TR4. Thus, the TR4 is activated and a current flows from a contrast adjusting signal line 9 and a color density adjusting signal line 10 to the TR4 in response to the level difference between the voltage level of a gain control signal and the Zener voltage of the ZD3 and flows to ground via a resistor 6. As a result, the voltage level of the contrast adjusting signal and the color density adjusting signal is dropped.
