Title: Air-fuel ratio feedback controller
Inventor: KIRISAWA TADASHI
IPC: F02D41/14
Filed: 1981-05-13
Abstract: PURPOSE:To perform good responsive feedback control, in air-fuel ratio control of an internal combustion engine, by measuring flame light in a cylinder through plural light sensing diodes and calculating air-fuel ratio from spectral sensitivity characteristics. CONSTITUTION:Flames in a cylinder are colored yellow for a large proportion of fuel, blue for logical air-fuel ratio and blue white for a small proportion. Then a light sensing diode 9, high sensitive for red color, and light sensing diode 10, high sensitive for blue color, are embedded to a spark plug, and flames are directly detected through heat resistant glass, arithmetically operated with their difference in an amplifier 13 through operational amplifiers 11, 12, further linearized by an amplifier 14 to obtain an air-fuel ratio signal. This signal is input to a correction calculator circuit of microcomputer, and its output changes duty ratio of a solenoid valve. In this way, feedback control can be operated promptly after a start with an earlier response than an 02 sensor.

Title: Cold heat accumulating type cold storage chamber
Inventor: NAGAI JUNICHI
IPC: F25D16/00
Filed: 1989-03-23
Abstract: PURPOSE:To permit the storage of transporting articles in a cold storage chamber even during cold heat accumulating operation by a method wherein at least one set of a ventilating fan is operated in conjunction with a cold storage chamber temperature detector during the cold heat accumulating operation to control the amount of cold air invading into the cold storage chamber. CONSTITUTION:Cold heat accumulating operation is effected by operating a compressor 40. When cold heat accumulating agent 28 is cooled and solidified perfectly by a cooler 29 and the temperature of a cold heat accumulating temperature detector 44 gives a predetermined temperature, lower than a freezing temperature, a cold heat accumulating temperature detector 43 is operated and the operation of the compressor 40 is stopped. In this case, the inside of a cold storage chamber 36 is not cooled to a cold storage temperature and, therefore, the b-contact of a cold storage chamber temperature detector 39 is in a conducted condition and both of ventilating fans 30, 31 are operated to ventilate air. When the inside of the cold storage chamber 36 is cooled to the cold storage temperature, the b-contact of the cold storage chamber temperature detector 30 is released from the conducted condition thereof and, therefore, only the ventilating fan 31 is operated. The temperature in the cold storage chamber 36 is controlled at a set temperature by repeating above-described operation during cold heat accumulating operation whereby the temperature of transporting articles 48, carried into the cold storage chamber 36, may be controlled at a temperature within the range of set temperatures.

Title: Invader detector for prevension of crime
IPC: G08B13/19
Filed: 1992-03-27
Abstract: PURPOSE:To accurately detect an invader while surely preventing the generation of malfunction by providing this invader detector with a sensitivity changing means for raising the detection sensitivity of an invader when an output signal level from a sound sensing means exceeds a prescribed value. CONSTITUTION:In an ordinary state, the output of a comparator 9 is in a low level, a transistor(TR) Q in an amplification factor variable circuit 6 is in an OFF state and the amplification factor of an amplifier A is previously set up so as to obtain comparatively low detection sensitivity. If an invader illegally invades, a sound wave with low frequency less than an audible area is converted into an electric signal by microphone 7, an amplification signal from the amplifier 8 exceeds the reference level of the comparator 9, a high level signal is outputted from the comparator 9, and the TR Q of the circuit 6 is turned on, short-circuiting the resistor R1. Since the amplification factor of the amplifier A is increased, the detection sensitivity of the device can be raised as the result. Consequently, the invader can surely be detected.

Title: Device and method for generating static magnetic field
Inventor: WAKUTA TAKESHI
IPC: G01R33/389
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a static magnetic field generating device suitable for obtaining the high magnetic field, the high spatial uniformity and the high time stability for improving the performance of a nuclear magnetic resonance analyzer. SOLUTION: A uniform magnetic field keeping means 2 by a cylindrical second kind superconductor to surround a sample space 11 is arranged inside a static magnetic field generating means, and a demagnetizing means of the uniform magnetic field keeping means 2 is installed. The uniform magnetic field keeping means 2 is formed of a superconductor, and has the magnetic shield function, and thus contributes to the time stability of the static magnetic field. Since the corrected magnetic field can be led to the sample space 11 by demagnetizing the uniform magnetic field keeping means 2, the magnetic field distribution of the sample space 11 can be controlled. Thus, the uniform magnetic field can be formed in the sample space 11 by repeating the correction of the magnetic field and the demagnetization of the uniform magnetic field keeping means 2.

Title: Outside holder for one-way clutch
Inventor: NUMATA TETSUAKI
IPC: F16D41/07
Filed: 1995-03-29
Abstract: PURPOSE: To provide an outside holder for a one-way sprag clutch which is so constituted as to be a low-cost and perform reliable fixing to an outer ring. CONSTITUTION: An outside holder for a one-way clutch comprises an annular main body part 4; and an insert-molded rib body 42 made of synthetic resin. The main body part has a columnar part 4b to partition adjacent sprag insertion holes 4a from each other. The columnar part 4b has an insertion hole 4c blanked by a press. The rib body 42 has a base part 43 extending along the columnar part 4b and a leg part 44 inserted in the insertion hole 4c of the columnar part 4b. Thus, since the main body part is made of a metal and is hardly thermally deformed, the outside holder is reliably fixed to an outer ring. Since insert molding is applied, a manufacturing cost is more reduced compared with a case wherein a conventional drug grip is used.

Title: Magnetic recording and reproducing device
Inventor: TAKAHASHI MARIHO
IPC: H04N5/93
Filed: 1990-03-23
Abstract: PURPOSE:To improve reproducing quality at the time of special reproducing by replacing a demodulated video signal with a signal at a fixed level while the detection output of a head reproducing signal, for which the reproducing signal of each rotary head is demodulated to the video signal, is lower than the fixed level and inserting a signal corresponding to a horizontal synchronizing signal during the period of this replacement. CONSTITUTION:The respective head reproducing outputs of heads 21 and 22 reproduced from a magnetic tape are alternately switched for each field and demodulated to the video signals by a picture processing circuit 25. Simultaneously, the output of a switch 24 is detected by a detection circuit 26 and the detection output is compared with a reference voltage by a comparator 27. When the output of the detection circuit 26 is smaller than the reference voltage, the demodulated video signal from the picture processing circuit 25 is inputted to one input terminal B of a switch 28 and the signal inserting the signal corresponding to the horizontal synchronizing signal to the signal at the fixed level is inputted to another input terminal L. Thus, one part of the projected picture is not damaged and the reproduced picture of the high quality can be obtained without noise.

Abstract: PURPOSE:To determine an end position of a pattern without being affected by a ground material or material of a mark by giving a specified offset value to differences among position coordinates of feature points based on both ends of the pattern among signals which are obtained when the pattern is scanned by a beam traversing it to determine a length thereof. CONSTITUTION:A deflection control unit 6 is controlled with a computer 7 and an electron beam scanning signal is supplied to a deflector 5 traversing a pattern 2 on a material 1 from this unit. Then, a secondary electron generated is detected with a detector 8 to be stored into a frame memory 11 through an amplifier 9, and A/D converter 10 and the computer 7. Thereafter, with the computer 7, peak positions XP1 and XP2 related to both ends S1 and S2 of the undersurface of the pattern 2 are determined from a profile which is stored in the memory 11. Thus, differences a and b between end positions are determined by a= (XP2 - XP1) k/100 (k: % of proportional constant) and b= (XP4 - XP3) k/100 and a width is determined by p= (XP4 - b) - (XP3 + a).
