Title: Pushbutton dial-in system
Inventor: NISHIMURA KOUJI
IPC: H04Q3/58
Filed: 1983-10-28
Abstract: PURPOSE:To make it possible to dial-in to an extension telephone directly from an external telephone by providing a limited signal detecting circuit which detects a special signal from an originating side to PBX. CONSTITUTION:Incoming to a main-wire trunk 8 is executed through station exchanges 11 and 10 by a dial of a subscriber telephone 12. When the trunk 8 answers for this incoming, the telephone 12 sends a special signal. When a limited signal detecting circuit 9 detects this limited signal, a switch network 6 connects the detecting circuit 9 to a pushbutton signal receiving circuit 5. Next, the receiving circuit 5 receives an extension number by a pushbutton signal which is sent from the telephone 12 following the limited signal. Then, the network 6 connects an extension telephone 1, which corresponds to the received extension number, to the trunk 8. In this way, it is possible to dial-in from the external telephone to the extension telephone directly.

Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To achieve a method for measuring the amount of aberration of a projection optical system that can measure the amount of aberration from the difference in line width between both ends even in a fine pattern where the pattern line width is less than 0.2 μm. SOLUTION: A resist film on a substrate is exposed to light by a mask where a line-and-space(LS) pattern is provided, and the exposure is repeated for a plurality of times with a plurality of quantities of exposure, thus obtaining the difference in line width between both ends of the LS pattern in each quantity of exposure light. Then, the difference in line width between both ends in the reference quantity of exposure (optimum quantity of exposure) is estimated from the relationship between the difference in the line width between both the ends and the quantity of exposure, thus obtaining aberration in the reference quantity of exposure.

Inventor: ITO TORU
IPC: G01C21/00
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a positioning system which provides only a prescribed user with high-accuracy correction data for GPS positioning correction. SOLUTION: Differential global positioning system(DGPS) data which is obtained from FM broadcast waves is fetched by a DGPS data fetch part 226. At this time, an adjustment error is added to correction data which is used actually to correct a positioning operation in the obtained DGPS data, and the accuracy of the correction data is not so high. A correction-value creating part 228 judges which data in a correction-value table 230 is to be read out from the content of the DGPS data. A system for the judgment is decided in advance. Then, a corresponding correction value is read out from the correction- value table, and a correction value is created. Then, the correction value and the correction data are added in a DGPS data designation part, and correct correction data is obtained. High-accuracy position information is obtained from the obtained correct correction data.

Abstract: PURPOSE:To provide an air battery that restricts the permeation of steam and carbonic acid gas in the air into the inner part, enables discharge for a long period of time, has excellent retention characteristics, and fully prevents the leakage of an alkaline electrolyte by using a composite film with excellent oxygen gas selection transmission capacity. CONSTITUTION:The air hole 8 of a metal air battery is blocked up from the inner part of the battery by using a composite film 9 with two-layer structure in which a thin layer made of metal oxide provided with oxygen adsorption capacity is integratedly attached to one side of a porous film with micropores of 0.1mum or less in pore diameter. For example, such a porous film can include a porous fluororesin film, porous polycarbonate film, porous cellulose ester film, and porous polyethylene film. A metal oxide with oxygen adsorption capacity indicates an oxide that has oxygen as a molecule on the surface and in the inner part of the metal oxide or an adsorption property as an ion and, to be concrete, tin dioxide (SnO2), zinc oxide (ZnO), cuprous oxide, manganese monoxide, nickel oxide, cobalt tetroxide, etc. Though this composite film has an extremely thin thickness, it will not transmit steam in the air. As a result, the film has an excellent oxygen gas selection transmission capacity.

Title: Optical coupling type relay circuit
Inventor: MATSUMOTO TAKESHI
IPC: H03K17/78
Filed: 1989-08-03
Abstract: PURPOSE:To speed up the turn-off of a relay by using a 2nd control transistor(TR) so as to decrease a gate charge of an output MOSFET. CONSTITUTION:A 2nd control TR 7 of normally-off type is connected in parallel with an impedance element 5 to bias a control TR 4 of normally-on type into a high resistance state and the gate connects to a photo diode array 2 in photo- coupling with a light emitting diode 1. Thus, when an input signal is applied to the light emitting diode 1, the optical current generated in the photo diode array 2 is supplied to impedance elements 5, 6, which bias the TR 4 into a high resistance state, then an output MOSFET 3 receiving an optical electromotive force of the photo diode array 2 is energized. Moreover, the control TR 7 is biased to a low resistance state and the resistance of the impedance element biasing the TR 4 to a high resistance state is apparently decreased. Thus, turn- off is quickened.

Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To constantly control the amount of input power by providing a means for modulating the time ratio of the output rectangular wave of a drive means according to a DC input voltage. SOLUTION: A rectification smoothing circuit 50 is mainly formed by an inductor 51 for resonance, a rectification diode 53, and a capacitor 55 which plays a role of a smoothing filter being connected in parallel between the output terminals of a piezoelectric transformer 40. A sinusoidal wave V2 which is rectified and smoothed by the rectification smoothing circuit 50 is outputted to a load 60, at the same time is detected by a detection means 70, and is subjected to frequency modulation by a frequency modulation circuit 80. Then, a drive circuit 90 drives a switching circuit 30 in synchronization with the output from the frequency modulation circuit 80. Also, a PWM circuit 100 is added and the time ratio of an output rectangular wave from the drive circuit 90 is modulated according to an input voltage. When controlling the input voltage fluctuation only by frequency modulation, frequency needs to be greatly changed and hence efficiency greatly decreases. Therefore, the load of frequency control is reduced by PWM.
