Title: Inspecting device for semiconductor integrated circuit
Inventor: SHIBATA HIROYUKI
IPC: G01R31/28
Filed: 1993-09-28
Abstract: PURPOSE:To accurately obtain the threshold voltage and the hysteresis width voltage of the input buffer of a semiconductor integrated circuit in a short time. CONSTITUTION:A signal bar INIT is outputted from a tester controller 23 to initialize individual circuits, then a signal MODE for setting the circuits to the measurement mode to obtain the threshold voltage. Measurement is started when a signal bar START is outputted from the tester controller 23, and the voltage VI having a linear wave-form with an inclination alpha is applied to an input buffer 21 from a chopping wave generator 25. A comparator 30 compares the output voltage VO of the input buffer 21 with the logical judgment voltage VC in response to it. If they are matching with each other, the voltage of a matching COM is made a high level. A time measuring circuit 31 measures the time from the measurement start until the voltage of the signal COM is made the high level, and the tester controller 23 calculates the threshold voltage from the inclination alpha and its time.

Title: Method and device for processing image
Inventor: SUZUKI KAZUHIRO
IPC: B41J2/52
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for processing an image by which it is possible to print the conspicuously variable part of an image gradation at the resolution of the original image data as it is and also print data without affecting the gradation of a halftone region through simple data conversion at low cost, and provide further an image processing device using the method. SOLUTION: k pieces of pixels are grouped as one set, and the gradation width is allocated to each of the pixels of the set. That is, the gradation width of a (i-1) to ai is allocated to an i-th image, and if the number of gradations (x) falls within this gradation width, it is set that the number of gradations after conversion xi=fi (x). If the number of gradations (x) is larger than ai, it is set that the number of gradations after conversion xi=mi. Further, if the number of gradations x is a (i-1) or lower, the number of gradations (x) is set that the number of gradations after conversion xi=ni. Thus the gradation width to be allocated to original image data is expressed by k pieces of pixels in the less variable part of the image gradation.  Since the number of gradations is decided by the gradation width of each of the pixels, conversion per pixel is performed in the widely variable part of the image gradation to keep the resolution unchanged.

Title: Semiconductor optical element
Inventor: TOKUDA YASUKI
IPC: H01S5/06
Filed: 1988-09-26
Abstract: PURPOSE:To change the oscillation wavelength greatly by controlling current that flows to an electrode so as to change resonance loss, and making the wavelength of oscillation between quantum levels in a quantum well activation layer variable. CONSTITUTION:This is made into the one of such resonator length that the oscillation of n=2 can be obtained in case that, for example, currents I2 are let flow only to an upper electrode 2. Hereupon, if currents I1 and I3 are further let flow to upper electrodes 1 and 3 too on both sides, wave guide paths combines, and effective width of the wave guide expands, and resonator loss decrease, Accordingly, it oscillates with low injenction currents, and changes to intertransition oscillation of n=1, and charges into long wave length. The amounts of this change can be made greater, the thinner the thickness of a quantum well activation layer 21 is made, for example, when the quantum well activation layer 21 is made in about 100Angstrom , the width of change becomes about 500Angstrom . For the center position of oscillation, if I1=I3, the oscillation can be done similar to the case that only I2 are injected below the upper electrode 2. Also, if the currents are injected so that it may be I1 I3, the position of its oscillation can be shifted.

Title: Heat roll fixing type magnetic toner for developing magnetic latent image
Inventor: ASANAE MASUMI
IPC: G03G9/087
Filed: 1985-10-29
Abstract: PURPOSE:To maintain an image density at a high level by heating toner particles to the temp. higher than the softening point of a thermoplastic resin to provide smooth surfaces thereto. CONSTITUTION:This toner consists of toner particles contg. the thermoplastic resin of which the melt viscosity at 150 deg.C is in a 1X10<2>-1X10<3> poise range and magnetic powder. The toner particles are produced by throwing ground powder into a mixer such as super mixer or Henschel mixer and agitating and mixing the same until the temp. of the ground particles is higher than the softening point of the thermoplastic resin. The angled parts after grinding are removed by such mixing treatment, by which the spherical or nearly spherical particles having the smooth surface are obtd. Hot offset is liable to arise if the melt viscosity of the thermoplastic resin is <1X10<2> poise and the fixability is lower if said viscosity exceeds 1X10<3> poise.

Title: Stopper for vibrationproof mount
Inventor: YAESAWA KOJI
IPC: F16F13/08
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To secure accuracy for the operation of a stopper by making the other stopper higher in height while being directed to the direction toward which one stopper part can easily slip. SOLUTION: When downward load P is applied from above, one mounting part 1 is lowered down so as to allow an elastic body 5 to be elastically deformed, and when one stopper part 7 abuts against the other stopper part 8, relative displacement between one mounting part 1 and the other mounting part 3 is thereby suspended, and it is thereby suspended that the elastic body 5 between both the mounting parts 1 and 3 is furthermore elastically deformed.  Besides when greater load is obliquely applied, and when both the stopper parts 7 and 8 abut against each other, the abutting surface 7a of one stopper part 7 comparatively high in height is tried to slip toward the outer circumferential direction with respect to the abutting surface 8a of the other stopper part 8, since the outer circumferential surface of the other stopper part 8 is higher in height than its inner circumferential surface, and supports one stopper part 7, one stopper part 7 is prevented from slipping, and occurrence of falling down can thereby be prevented.
