Abstract: PURPOSE:To suppress deterioration in spatial resolution due to a spot light source which is not at a focal point and also attain high-precision detection without any deterioration in resolution by providing a position quantizing circuit consisting of a delay circuit, comparing circuit, and conductional decision circuit. CONSTITUTION:An analog signal is inputted from a terminal A and five delay signals are outputted from a delay circuit 31. An intermediate delay signal among them is inputted to a delay circuit 32 to output five delay signals. Delay signals of those two delay circuits except intermediate delay signals are delayed through a delay circuit 33 by the same time with the intermediate delay signal of the delay circuit 32, and the comparing circuit 34 compares and output signal level and a specific set voltage VR on the basis of the intermediate delay signal of the delay circuit 32 as a reference value. Further, a comparing circuit 35 compares the leves of the input to the delay circuit 32 and other delay signals. A conditional decision circuit 36 outputs a significant signal on the basis of the output signals of both comparing circuits 34 and 35 while the intermediate delay signal of the delay circuit 32 exceeds all other delay signal levels.

Inventor: INOUE TAKESHI
IPC: H03H9/58
Filed: 1982-02-25
Abstract: PURPOSE:To simplify the process of frequency adjustment of a piezoelectric oscillator remarkably, by arranging resonance frequencies in a basic constitution section of a ladder type piezoelectric filter so as to be increased or decreased in order at each basic constitution section. CONSTITUTION:The ladder type piezoelectric filter comprising piezoelectric oscillators a1-a9 arranged in series and parallel capacitors C is provided with the basic constitution sections (a1 and a2, a3 and a4, a5, a6 and a7, and a8 and a9). The basic constitution sections are arranged from the input side in order so that the resonance frequency of the piezoelectric oscillators of each section are increased, or decreased, allowing to obtain entirely the same characteristics as the case with the strict adjustment of each oscillator without distorting the pass band characteristics.

Title: Suction air flow detector for internal-combustion engine
Inventor: TOMIZAWA NAOMI
IPC: G01F1/68
Filed: 1994-02-28
Abstract: PURPOSE:To enhance accuracy in the detection of suction air flow of an internal-combustion engine by discriminating between the reverse flow generating period and nongenerating period based on the switching state of a suction valve and operating the reverse air flow rate during the reverse flow generating period thereby correcting the suction air flow rate based on the output from an air flowmeter. CONSTITUTION:A crank angle detected by a crank angle sensor 14 is read into a control unit (C/U) 12 and a predetermined time interval after closure of a suction valve 10 detected through an open/close sensor 11 is decided as a reverse flow generating period and other time interval is decided as a reverse flow nongenerating period. During the nongenerating period, a suction air flow Q detected by an air flowmeter 13 is stored as a true air flow MQ in the C/U 12. During the generating period, an initial reverse flow Q' is retrieved from a map table based on the stored flow MQ and an opening VTO detected by a throttle sensor 9 and a sequential reverse flow Q'' is determined based on the flow Q' and the crank angle. A true suction air flow MQ' is determined by substracting the reverse flow Q from the flow Q detected by the air flowmeter 13.

IPC: C09K3/18
Filed: 1985-02-18
Abstract: PURPOSE:To obtain a thawing agent having an excellent solar energy absorption capacity and capable of rapidly melting snow by spreading it over a snow surface, by breaking a black slate by giving a percussion by means of a centrifugal crusher to the flat side thereof to break it into more flat fragments. CONSTITUTION:An intended thawing agent is prepared by supplying a black slate to a centrifugal crusher and breaking it into more flat fragments while giving a percussion to the flat side thereof to obtain a small grain improved with respect to flatness. The thawing agent can absorb a solar energy efficiently. Further, since it has a specific gravity of about 2.7 which is suitable for spreading it from the air, when spread from a height over a snow surface, it does not scatter away in the distance by being carried on a wind, leading to no pollution, since the thawing agent contains as essential ingredients trace amounts of iron, manganese, calcium, copper, etc., when spread over the snow lay on golf links, it can not only melt snow but also accelerate the growth of grass.
Patent JP-H10227697-A (JP)
Title: Noncontact temperature measuring sensor
Inventor: MASUTANI TAKESHI
IPC: A61B5/01
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a noncontact temperature measuring sensor whose measuring accuracy is enhanced by a method wherein a light guide device having a taper- shaped inner face is arranged between an optical lens and an object to be measured, the sensitivity at the periphery of the optical lens is attenuated and the visual-field characteristic of the optical lens is made sharp. SOLUTION: A light guide device 5 has a taper-shaped inner face which is converged on the side of an optical lens 2. Infrared rays which are radiated from an object to be measured are guided to the optical lens 2 by the light guide device 5 so as to be incident on an infrared sensor 1. While an incident beam at a critical angle of incidence or higher decided by the taper angle of the light guide device 5 is reflected on the inner face of the light guide device 5, its angle with reference to an optical axis becomes gradually large so as not to reach the optical lens 2. The incident beam at the critical angle of incidence or lower reaches the optical lens 2 directly or after its reflection. By this action, the light guide device 5 has an effect to correct a visual-field characteristic. When the taper angle is set properly, the sensitivity at the periphery of the optical lens 2 is attenuated so as to be brought close to the visual-field characteristic of an ideal lens.

Title: Distance detector
Inventor: HORIGUCHI CHIYOHARU
IPC: G01C3/00
Filed: 1988-02-10
Abstract: PURPOSE:To obtain a distance detector which detects the distance to an object even when the object is placed nearby a projection an auxiliary projecting means in addition to a main projecting means which projects a propagation medium on the object. CONSTITUTION:This detector is provided with a light source 2 which outputs light, a projection lens 3 which is optionally settable in the spread angle theta ' of the emitted luminous flux, a photodetection lens 5 which converges and guides the reflected light from the object 4 to a photodetecting element 6, and an element 6 which converts the reflected light photoelectrically. Further, an auxiliary light source 21 is provided to an L-shaped member 20 and used when the object 4 is placed nearby, and light is outputted at a specific spread angle. Consequently, the light from the light source 2 is projected at the small spread angle theta ' so as to detect the distance L to the object 4 with good sensitivity, so when the object is placed nearby, the whole or majority of the reflected light of the light from the light source 2 is cut off and when the intensity on the element 6 decreases below a specific value, the light source is switched to the auxiliary light source 21 to project the light on the object. The distance to the object 4 when the object 4 is placed nearby the detector 1 is therefore detected.

IPC: B63B35/32
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To efficiently oil recover by forming the stern end of a hull into a transom shape, arranging an oil recovering/processing facility in the hull, and largely opening an oil inflow port communicating with the oil recovering/ processing facility to the above and below of the draft line on the stern face. SOLUTION: A propelling/steering system with a two-shaft two-rudder structure fitted with drag rudders on both the starboard and port of a hull 1 is freely used to steer the hull 1 so that the stern is invariably directed to the wind. Floating oil is introduced from an oil inflow port 4 largely opened at the stern end of the hull 1 and flows into the oil recovering/processing facility 2. Since the stern end is formed into a transom shape, the oil recovering work can be stably conducted with high efficiency even in high waves. Propellers 11 can be horizontally rotated at all angles, an oil recovery operation room 7 is faced in the stern direction, thus the operation to direct the stern to the wind can be easily maintained. The oil inflow port 4 at the stern end is closed by a cover 12 at the time other than the oil recovering work.
