Title: Modulating circuit of biphase mark
Inventor: ITOI TETSUSHI
IPC: H03M5/12
Filed: 1983-01-31
Abstract: PURPOSE:To obtain an inexpensive biphase mark modulating circuit of simple constitution by combining a counter and a gate circuit in special constitution. CONSTITUTION:A 1.5 bit signal B generated by the 1st counter 1 has a period one and a half times as long as the bit period of a data signal; and a synchronous generation period signal D appears at an output Q of an FF6 and an asynchronous generation period signal E appears at an output Q'. A bit clock generating circuit 7, on the other hand, generates a bit start signal I and a bit center signal L indicating the center part of each bit, and they are led out through a gate 21; and a gate 20 checks on the coincidence between the output signal of an inverter 19 which inverts the signal B and a signal D and a gate 22 checks the coincidence between the output signals of the gates 20 and 21 and a block synchronizing signal A to obtain an inversion position signal M. An FF23 is triggered by this signal M to obtain a biphase mark modulated signal N which is inverted every time the signal M is generated.

Title: Sensor for detecting concentration of gas
Inventor: TAKEGAWA TOSHIYUKI
IPC: G01N21/61
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To easily make optical path aces of laser lights agree, by fixedly setting a laser light-oscillating part at one end part in a cylindrical case projecting into a gas and a light-detecting part at the other end part, and forming a plurality of slits penetrating a central part of the case at the central part. SOLUTION: When a sensor 10 is fitted to a duct via a mounting flange 2, a gas circulating in the dust flows into a case 11 through a slit 20 and flows out through the slit 20. When a control current is impressed to a laser light- oscillating part 15 via a conductor 17 from a control power source, a laser light 23 is oscillated, passes a protecting window 24 and is projected to the gas circulating in the case 11. After the laser light is attenuated in a wavelength band corresponding to a type of the gas, the light is detected at a light detecting part 16 through a protecting window 25. An output signal from the light- detecting part 16 is sent to an analyzing apparatus through a signal conductor 18, so that a concentration of dust is detected.  The laser light-oscillating part 15 and the light-detecting part 16 are fixedly set inside the case 11, and moreover, the case 11 is cooled and not deformed by heat. Accordingly, an optical path axis of the laser light 23 is never deflected.

Abstract: PURPOSE:To form a transistor of LDD structure having a source drain diffusion interval equal to minimum resolution dimension by a method wherein a mask layer left in a gate region is used as a mask, and a polysilicon gate electrode whose section has a trapezoidal shape is formed by selectively oxidizing a polysilicon film. CONSTITUTION:On the surface of a semiconductor substrate 601, a polysilicon film 605 is formed via a gate oxide film 604. A mask layer 609 formed on the film 605 is left only on a gate region. The polysilicon film 605 is oxidized by high pressure oxidizing method using the mask layer 609 as a mask. Thus a gate electrode 612 whose section has a trapezoidal shape is formed under the mask layer 609, by using the residual polysilicon film 605. The other polysilicon films are all converted into an oxide film 610. After unnecessary oxide films except gate electrode are eliminated, impurity is ion-implanted by using the mask layer 609 as a mask, and the diffusion layers 614, 615 for a source drain are formed. After that, the mask layer 609 is eliminated, and impurity is ion-implanted on the whole surface, thereby forming a low concentration layer 616 under both sides of the gate electrode 612 whose section has a trapezoidal shape.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent cracks in a waterproof layer, by forming a peeling layer preventing a waterproof layer formed by a waterproof work from sticking, to the surface of cracks or concrete or the like at an expected position of cracks. SOLUTION: When constructing a waterproof structure, after concrete C surface CS has been scraped, a peeling layer 1 is formed at nearby position of cracks W. A release agent or the like preventing the concrete layer C and the waterproof layer P from generating an adhesive force, is applied on the peeling layer 1. The peeling layer 1 may be formed by sticking paper, cloth, tape, etc. Thereafter, a conventional waterproof method is executed. This preventing method can be applied for cracks or expected parts of cracks such as extended parts of cracks arisen after a waterproof work. In this way, a tensile strain arisen in the waterproof layer P near cracks W of the concrete C can be extremely lessened. And hence, this method can prevent fissures which will be brought in the waterproof layer P by the cracks W.
