Title: Epoxy resin composition suitable for laser printing
Inventor: SASAI SHOJI
IPC: B41M5/26
Filed: 1989-07-28
Abstract: PURPOSE:To prepare an epoxy resin compsn. which, when applied to the surface of an electric or electronic part as an insulation coating, forms a coating film capable of being clearly printed by laser irradiation without adversely affecting the electrical and other properties by compounding an epoxy resin compsn. with silver acetate. CONSTITUTION:An epoxy resin compsn. comprising an epoxy resin, a hardener, a filler, etc., is compounded with silver acetate pref. having a mean particle diameter of 100mum or lower pref. in an amt. of 0.5-20wt.% based on the compsn. Silver acetate, a colorless crystal, undergoes deacetylation when heated to 150-250 deg.C into silver oxide (I), a black substance. Hence when the epoxy resin compsn. contg. silver acetate is irradiated with laser beams in accordance with a character or pattern, only an irradiated part of the surface of the compsn. turns black, leaving an unirradiated part white and thus a clear black printing of the character or pattern on a white substrate is made possible.

Title: Ultrasonic motor
Inventor: NAGATOME SEIICHI
IPC: H02N2/00
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion powder from being diffused to have adverse effect through a simple arrangement without increasing the number of parts by composing the oscillator and the mover of an ultrasonic motor of a magnetic material and magnetizing any one of them. SOLUTION: The ultrasonic motor comprises a piezoelectric element, an oscillator and a mover 60. The mover comprises oscillatory pieces 6, 8, oscillator members 10, 16, fixed members 22, 24, 26, 28, and a connecting member 32 formed integrally of a planar conductive and magnetic metallic material. The mover 60 employs a magnetic material having hardness lower than that of the oscillator material. The oscillator or the mover 60 is subjected to magnetization. Consequently, abrasion powder generated between the oscillatory pieces 6, 8 and the mover 60 is attracted to the oscillator or the mover 60 and prevented from scattering into an apparatus. When the oscillatory pieces 6, 8 are magnetized only partially, abrasion powder can be prevented from being caught at the contact part between the mover 60 and the oscillator.

Title: Detection of burying of lead
Inventor: MATSUZAKI HIROFUMI
IPC: G01N21/956
Filed: 1988-08-03
Abstract: PURPOSE:To enable detection of a burying of the tip of a lead in a solder by an optical means by utilizing a light reflection characteristic of a soldered part and the lead. CONSTITUTION:An optical scanning is performed widthwise at a base end part of a lead l to set a point (a) equally dividing a lead width. Then, with the point (a) as starting position of the optical scanning, the optical scanning is performed by a specified distance D along the length of the lead L. Then, when a light presentation continues in the brightness, with no change from a light to dark level, the tip of the lead L is determined to be buried in a soldered part 9. On the other hand, a filet 10 is observed dark with a camera 3 as light incident from above is reflected sideways while the brightness is changed clearly to a dark level thereby enabling the confirming of the presence of the filet 10. This simplifies the detection of whether the tip of the lead is buried in a solder or not.

Title: Antiskid control device
Inventor: YASUI YOSHIYUKI
IPC: B60T8/1761
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To secure a stable brake action by adjusting control parameters accord ing to the estimated results of a brake rigidity estimating means estimating the brake rigidity based on the value corresponding to the braking force applied to each wheel and a wheel speed. SOLUTION: The parameter S1 and/or S2 of a slip ratio is set to a shallower value when the brake rigidity BS is estimated as larger that when it is estimated as small.

Filed: 1991-07-10
Abstract: PURPOSE:To enable a good reproducing to be carried out by automatically adjusting a waveform equalization factor in accordance with the degree of frequency degradation by the interference between codes of a regenerating signal. CONSTITUTION:The regenerating signal is synthesized with a reflected signal from an open terminal (b) in the matching terminal (a) of a delay element 1, and the sum signal is performed k-times by an attenuator 2 and sent to a differential amplifier 3. The regenerating signal, as well is inputted to the amplifier 3 through the element 1, and a waveform equalized signal corrected to an original input signal is obtained as this output. Then, when a difference between the peak value and the bottom value of a preamble signal is large relatively and the frequency degradation in a high band is small relatively, a control signal so as to reduce an attenuation factor (k) is outputted from a signal converting circuit 9 to the attenuator 2. When an opposite occasion, the control signal to increase the attenuation factor (k) is outputted. Thus, the attenuation factor (k) is varied automatically in accordance with the degree of the frequency degradation of the regenerating signal, and the waveform equalization factor is adjusted to the optimum value.

Title: Linear motor and stage device or aligner using the same
Inventor: KAMATA SHIGETO
IPC: H01L21/027
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To increase the output of a jacket by suppressing the deformation and breakage of the jacket even when the pressure of a coolant is increased or the size of the jacket is reduced, by providing a reinforcing member which reinforces the jacket against the pressure of the coolant in the jacket. SOLUTION: In a linear motor, a reinforcing member 8 is stuck or bolted to both sheets 4 and 4' as a pressure-resistant tool which prevents the expansion of the interval between the sheets 4 and 4'. In this linear motor, the heat generated from a coil 1 when the coil 1 is energized is recovered so as to suppress the temperature rise of the coil 1 itself and a device, etc., mounted with the linear motor, by making a temperature-controlled coolant flow to the internal space 6 of a jacket. When the coolant is made to flow, the reinforcing member 8 suppresses the deformation of the sheets 4 and 4' which are expanded outward by the pressure of the coolant.  Therefore, the cooling efficiency of the jacket can be improved by increasing the flow rate of the coolant and, at the same time, the size of the jacket can be reduced, because the deformation or breakage of the jacket can be suppressed even when the pressure of the coolant is raised or the thicknesses of the sheets 4 and 4' of the jacket are reduced.

Abstract: PURPOSE:To surely improve the restart performance of an engine by constituting a flow rate control valve in a bypass passage of a throttle valve so as to be opened when the revolution speed on the stop of an engine reduces below the set revolution speed. CONSTITUTION:When the number of revolution reduces for the stop of an engine 1, the intake pressure on the downstream side of a throttle valve 12 gradually increases to the atmospheric pressure line. ln this case, if the engine revolution speed reduces lower than a set revolution speed, a flow rate control valve 11 is opened immediately for a certain time, and if the engine 1 stops, the valve is opened successively. Therefore, a bypass passage 15 is opened before the perfect stop of the engine 1, and the intake pressure on the downstream side of the throttle valve 12 is speedily increased to the atmospheric pressure line. Therefore, when the engine 1 restarts, the actual atmospheric pressure can be detected from the downstream side of the throttle valve 12 by a pressure sensor 7, and also the quantity of the fuel jetted out from a fuel injection valve 4 can be set to the quantity which is most proper for the air density and the engine state, and the restart performance of the engine 1 can be surely improved.
