Title: Distribution line carrier signal transmission system using differential phase modulation
Inventor: TORIKAI TAKAYUKI
IPC: H04B3/54
Filed: 1988-02-09
Abstract: PURPOSE:To attain high speed and sure transmission by sending a signal with differential phase modulation, and allowing a reception side to apply differential demodulation. CONSTITUTION:A 60Hz synchronizing pulse synchronized with a commercial frequency is generated from a commercial frequency synchronizing pulse generator 3. A data pulse synchronously with a synchronizing pulse is generated with the information code to be space from a serial data generator 4 according to the inputted information code (60bps). A commercial frequency zero cross phase correction device 6 generates a signal (g) of a waveform being the inversion of the latter half phase of each one bit period of the output (f) of a phase modulation generator 5 based on an output (b) of the commercial frequency synchronizing pulse generator 3. The signal (g) controls the energization of a switching transistor 7. Then a load current (h) flows to a load resistor 8 via a rectifier 9 in response to the control and the current is injected to a distribution line via a pole transformer.

Title: Electric heating type catalyst
Inventor: KOMATSUDA TAKU
IPC: F01N3/24
Filed: 1995-02-15
Abstract: PURPOSE: To prevent the occurrence of a crack owing to concentration of a thermal stress by a method wherein the inner end part of a slit formed internally of the outer peripheral wall of a catalyst carrier forms a gas part having width wider than that of the slit. CONSTITUTION: The inner end part 5b of a slit 5 is enlarged approximately in the shape of a key hole. Thereby, when a catalyst carrier 2 is heated by high temperature exhaust gas exhausted from an internal combustion engine or when, during energization, a current is concentrated to the internal end part 5b of the slit 5 and temp is increased, a stress generated owing to thermal expansion is also dispersed at the internal end part 5b of the slit 5. Thus, since a local stress is not concentrated to the internal end part 5b, a problem, such as the occurrence of a crack, is prevented from occurring, durability is improved, and stable use for a long time is practicable.  Further, since the peripheries of through-holes 2b..., the periphery of the slit 5, and the periphery of an internal end part 5b are all partitioned by partition walls 2a... having the same thickness, a thermal stress is approximately uniformly used on the walls 2a... and durability of the catalyst carrier 2 is improved.

Abstract: PURPOSE:To facilitate the insertion of an electronic part mounting base into a protective enclosure and provide stable vibration isolation, regardless of the accuracy of the inside diameter of the enclosure, by placing a vibration isolating elastic material on both sides of the mounting base, and tightening a ring screw to press, deform and bring the elastic material into tight contact with the enclosure. CONSTITUTION:Electronic part mounting bases 2 and 3, joined by a joining member 7, are smaller than the inside diameter of a protective enclosure 1, and thus easily placed thereinto. The mounting bases 2 and 3 are clamped together between both ends of the protective enclosure 1 using spacers 8, and secured by tightening ring screws 6. By further tightening the ring screws 6, the mounting bases are pushed toward the center of the enclosure 1. The joining member 7 and spacers 8 are pressed from left and right; consequently, they are axially deformed, expanded and brought into close contact with the inside surface of the protective enclosure 1. In this state, vibrations and impacts by external force are absorbed in the joining member 7 and spacers 8 of engineer plastic.

Abstract: PURPOSE:To realize a driving device, which is simple and highly reliable and also superior in safety, for a semiconductor laser, by a method wherein a limited signal generating circuit capable of generating continuously a dummy photoelectric signal for a constant time since a point when a power source has been turned-ON is added in between the photo output detector and the current control circuit of the semiconductor laser. CONSTITUTION:Parts 3 of laser lights are incided in a photo output detector 4, the parts 3 are amplified in an amplifier 5 and an optical intensity signal 6 is obtained. A limited signal generating circuit 7 has been provided in between the amplifier 5 and a current control circuit 2. A signal 9 obtained by adding the optical intensity signal 6 to the output voltage 8 of this limited signal generating circuit 7 is compared with an optical intensity set value 10, and after that, the signal 9 is turned into an error signal 11 and the error signal 11 controls the output current of the current control circuit 2. Here, it is assumed that (to) is a non-control time, which is decided by the rise characteristics of the amplifier 5 and so forth, and Vo is an optical intensity set value. Under this condition, when a dummy photoelectric signal of a larger optical intensity value than the Vo is made to generate at least for a longer time than the (to), the output current of the current control circuit 2 dwindles into zero during the time. Accordingly, there is no possibility that a semiconductor laser 1 is broken even for a momentary turning-ON of a power source.

Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To expand measurable range, by setting generating voltage to zero intermittently with a programable high-voltage generator, and measuring conductivity only when the voltage is zero. SOLUTION: A programable high-voltage generator 21 placed in a high- voltage circuit 9 sets generating voltage to zero intermittently, and a zero- voltage detection relay 22 detects zero voltage. An automatic switching valve 23 samples measured liquid 3 into a capillary 1, and the measured liquid 3 travels through the capillary 1 such that component of the liquid is separated by high voltage generated by the programable high-voltage generator 21. A conductivity instrument 7 measures conductivity of the measured liquid 3 only when the zero-voltage detection relay 22 detects zero voltage. Thus, component of the measured liquid 3 can be analyzed, and quantitative analysis is also available based on size of the conductivity. Because high voltage for electrophoresis is not impressed during measurement, detail measurement of conductivity and measurable range are expanded.
