Patent JP-H08185928-A (JP)
Title: Socket for printed-circuit board
Inventor: YODOGAWA AKIHIRO
IPC: H01R13/629
Filed: 1994-12-21
Abstract: PURPOSE: To pull out a printed board easily by pressing a guide arm on an end face on the printed board side so that it is elastically deformed and the printed board can turn when the printed board is pulled out by an eject lever. CONSTITUTION: A finger application part 42 of an eject lever 40 is pressed down to pull out a printed board 8 from a socket 10. By pressing it down, projection pieces 52, 54 bend wall parts 26, 28 and escape from hold grooves 37a, 39a, and a hook part 44 pushes up the printed board 8 at the same time. The printed board 8 deforms a guide arm 64 elastically and turns so that more than a half of an edge part 6 of the printed board 8 is pulled out from an insertion port. Consequently, holding force of a spring contuact 12 is reduced to a half to pull out the printed board 8 easily.  Moreover, since both fringe parts of the printed board 8 are in guide grooves of guide parts 22, 24 and are guided even if the printed board 8 is in such a turning condition, the printed board 8 turns at a stable attitude in the same plane, and excessive turning of the printed board 8 is prevented by a connection wall 68.

Title: Depilator
Inventor: FUKUDA TADATOSHI
IPC: A45D26/00
Filed: 1993-12-20
Abstract: PURPOSE:To lower vibration and noise and to enable smooth depilation by rotating two spiral blades while attaching and detaching these blades. CONSTITUTION:This depilator instantaneously changes the rotating speeds of the plural spiral blades 2 in order to open and close these spiral blades 2. The depilator having the two spiral blades 2 rotates the one spiral blade 2 at a specified speed and varies the rotating speed of the other spiral blade 2. Namely, the instantaneous speeds of the one or both spiral blades 2 are changed in such manner that the two spiral blades 2 rotate relative to each other although the mean speeds thereof are the same. A rotational driving means 3 which rotationally drives the two spiral blades 2 drives pulleys 8 fixed to the spiral blades 2 by means of a belt 9. The pulley 8 fixed to the one spiral blade 2 is directly connected via the belt 9 to a driving shaft 12. The pulley 8 fixed to the other spiral blade 2 is connected via the belt 9 and an elliptic gear 11 to the driving shaft. This elliptic gear 11 pulsates the rotating speed of the spiral blade 2 by increasing or decreasing the rotating speed.

The evaluation circuit 16 measures the amplitudes of real signal at both positions 3 and 4. When these values are not more or less than a predetermined threshold, the output of the comparator is ignored.

Title: Photoelectric conversion device
Inventor: TOMOTA KOJI
IPC: H04N1/028
Filed: 1994-12-22
Abstract: PURPOSE: To set crosstalk quantity between signal wirings to be uniform and to make the quality of an output picture to be high by adjusting the floating capacitance of the crossing part of individual and common signal wirings from an optical sensor by means of wiring structure and making floating capacitance added to the common signal wiring to be the same. CONSTITUTION: The individual signal wiring 401 connected to the common signal wiring 501 at the outermost side of an FET part-side forms the crossing part with other common signal wirings by extending the wiring from a contact part 601. The area A of the crossing part becomes smaller than the area B of the other crossing part by thinning the wiring width of the wiring 401 in the crossing part. Floating capacitance formed in the crossing part of the individual signal wiring 401 and the common signal wiring 501 is made small by reducing the area of the crossing part. Furthermore, floating capacitance between the signal wirings including floating capacitance formed between an individual electrode and the wiring 501 is made equal.  Namely, the area of the crossing part A is adjusted and floating capacitance in the crossing part A is made smaller than floating capacitance in the crossing part B by the quantity of floating capacitance between the individual electrode, namely, an upper layer electrode wiring being the drain electrode of an FET part and the wiring 501 at an outermost part so as to reduce floating capacitance between the signal wirings.

Title: Image input device and image-processing system
Inventor: SONODA SHINYA
IPC: H04N1/38
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To allow the image input device, such as a digital camera to detect whether or not a detection object is included in picked-up image data. SOLUTION: An image of an object 10 is formed on to a CCD 13, via lenses 11, 12 for picking up the image. In this case, a magnification reduction rate calculation section 22 obtains a magnification/reduction rate of picked-up image data, based on a distance between the object and an image input device measured by using a distance calculation section 20 and a zoom amount obtained from a zoom switch 18. Then the image data are given to a magnification reduction section 21, where the data are normalized to data with a reference image size equal to that of reference data recorded in a dictionary 24, based on the magnification/reduction rate. A recognition section 3 takes matching with the reference data recorded in the dictionary 24, so as to discriminate whether or not the data are detection object data.  When the data are detection object data, a detection signal is fed to an image-processing section 14, in which a processing such as deletion of image data or deterioration of image quality is conducted, and the resulting data are recorded in a recording medium 15a.

Abstract: PURPOSE:To obtain the subject compound in high yield and efficiency under relatively mild reactional condition while suppressing the formation of by- product by reacting an aromatic bromide with an alcohol and carbon monoxide in the presence of metallic palladium and a basic inorganic substance. CONSTITUTION:An aromatic carboxylic acid ester useful as an intermediate for pharmaceuticals, agricultural chemicals, dyes or pigments, raw material for polymers, plasticizer, preservative, etc., can easily be produced in high yield and efficiency even under mild reactional condition (especially at normal temperature to 150 deg.C under 0.1-5kg/cm<2> pressure) by reacting an aromatic bromide with an alcohol and carbon monoxide in the presence of metallic palladium and a basic inorganic substance (e.g. hydroxide or organic carboxylic acid salt of alkali metal or alkaline-earth metal or alkaline-earth metal oxide) preferably at 50-250 deg.C under <=10kg/cm<2> pressure. Since there is essentially no formation of by-product, the present process is suitable as an industrial process.

Abstract: PURPOSE:To perform a writing operation with a small power, and to provide excellent universality, reliability and high integration by providing an insulating film to be dielectrically broken down upon heating by heat generated from a heat generator in a state that a predetermined voltage is applied from electrodes and to control stored data to be output to a bit line in breakdown state and in a non-breakdown state. CONSTITUTION:An FETM 1 is conducted in a state that a predetermined voltage is applied to an insulating film 11, the film 11 is heated by heat generated by supplying a current to a heat generator 12 through a writing bit line WB, the film 11 is broken down to shorten the FETM 1 to the generator 12, thereby writing. If the film 22 is broken down to be short-circuited, the potential of a reading bit line RB is lowered, while if the film 22 is not broken down, the potential of the line RB is not lowered, and stored data is read by the potential change. Thus, power of the writing operation can be reduced without complicating a manufacturing process, excellent universality and reliability as well as high integration are provided.
