Title: Switching circuit
Inventor: OKUYA KAZUO
IPC: H03K17/00
Filed: 1984-05-09
Abstract: PURPOSE:To attain the alternate output of the 1st and 2nd switch state signals in a prescribed cycle without using a trigger pulse, by using a switch means which delivers the 1st and 2nd state signals and a monostable multivibrator to form a switching circuit. CONSTITUTION:The 1st and 2nd state signals are supplied to a monostable multivibrator 30 from a switch means 28. The vibrator 30 delivers the 1st and 2nd switch state signals alternately to an output terminal 30b in a prescribed cycle to change over switch means 4 and 5 when the 1st state signal is supplied. While the vibrator 30 delivers the switch state through the terminal 30b immediately before the 2nd state signal is supplied in case the 2nd state signal is supplied. Then the means 4 and 5 are held in a single state. Thus the 1st and 2nd switch state signals can be delivered alternately in a prescribed cycle without using a trigger pulse.

Filed: 1993-03-31
Abstract: PURPOSE:To prevent short circuit between the gate electrode and the source and drain electrodes due to pinhole defect by isolating an n-type semiconductor film between the source and drain electrodes after patterning upper and lower blocking films and then removing the upper blocking film from between the source and drain electrodes. CONSTITUTION:After a gate electrode 12 is formed on a substrate 11, a gate insulation film 13, an i-type semiconductor film 14, a lower layer blocking film 17a, and an upper layer blocking film are formed sequentially thereon. The blocking films 17a, 17b are then patterned into a shape corresponding to the channel region of the i-type semiconductor film 14 followed by formation of an n-type semiconductor film 15 and a metal film 16. The metal film 16 is then patterned to form source and drain electrodes 16S, 16D and the n-type semiconductor film 15 is isolated between the source and drain electrodes 16S, 16D. Subsequently, both blocking films 17a, 17b are removed from the part between the source and drain 16S, 16D. This structure prevents short circuit between the source and the drain.

Abstract: PURPOSE: To improve close adhesion between photoresist and a semiconductor surface for preventing exfoliation of minute photoresist patterns by widening the width of a part of the width of the minute photoresist patern for wiring the electrodes to be formed on the semiconductor surface.  
     CONSTITUTION: After forming silicon oxide film 2 on the semiconductor surface by heat oxidation, photoresist 4 will be spread all over the surface and then selectively removed. Next, after removing silicon oxide film 2 under the mask of photoresist 4, photoresist 4 will be removed and further silicon oxide film 2 will be formed by heat oxidation for forming polycrystalline silicon film 3, which is to become gate electrodes. The said film 3 will be patterned to provide MOS transistor. When patterning photoresist 4, the minute photoresist pattern 5 consisting of a long and narrow pattern part 5a and the wide pattern parts 5b on both ends will be formed. By reason of the thus enlarged region of the pattern part 5b, the close adhesion between the photoresist and the semiconductor surface will be raised to prevent exfoliation of the minute photoresist patterns.

Title: Hybrid integrated circuit device
Inventor: MAKINO TAKAHISA
IPC: H05K1/16
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent influence of noise generated from a coil or the like, by forming an amplifier circuit to which voltage is supplied from a switching power supply circuit containing a coil, on a second thick film substrate. SOLUTION: A switching power supply circuit and an amplifier circuit are formed on the respective thick film substrates 11, 21. Since a current flowing in a coil is turned on and off by the above constitution, switching noise such as a flyback voltage leaks out from the coil. However, since the coil is formed on a first thick film substrate having conductivity, the switching noise is shielded with the first thick film substrate having conductivity. Thereby the switching noise can be prevented from exerting influence upon other peripheral equipment.

Title: X and y moving bases with vibration eliminating function
Inventor: KOBAYASHI ISAO
IPC: G05D3/00
Filed: 1988-04-20
Abstract: PURPOSE:To improve the accuracy of an apparatus by preventing a surface plate from moving by its reaction force, when (x) and (y) moving bases are driven by controlling a thrust of a (y) driving device and an (x) driving device. CONSTITUTION:When a (y) moving base driving signal YD for driving a (y) moving base 4 is transmitted, both a (y) driving device 7 and a (y) thrust generating device are driven. Lines of action of force of both of them coincide with each other, therefore, reaction force of a thrust generated by the (y) driving device 7 can be offset by the (y) thrust generating device 10. Also, when an X moving base driving signal XD for driving an X moving base 6 is transmitted, three of an X driving device 17, an X1 thrust generating device 11 and an X2 thrust generating device 12 are driven. As for these three devices, their lines of action are parallel, and also, they are in the same plane, therefore, reaction force of a thrust generated by an X driving device 8 can be offset by the X1 thrust generating device 11 and the X2 thrust generating device 12.

Title: 'kana'/'kanji' converter
Inventor: TAKAHASHI MASAHITO
IPC: G06F17/27
Filed: 1987-04-17
Abstract: PURPOSE:To form a reference description document by providing the title device with a word storing means for storing description data and storing reference description data. CONSTITUTION:When a 'KANA' (Japanese syllabary) character string is inputted from an input key 1a, the inputted data are stored in a character string storage part 2. When a conversion key 1b is depressed, a 'KANJI' (Chinese character) conversion control part 4 selects a 'KANA'-'KANJI' mixed output character string from a word dictionary 5 for the data of the 'KANA' character string stored in the storage part 2 under control based upon an edition control part 3. Consequently, plural character strings are displayed on a display device 7. When a prescribed key is depressed, a reference description retrieving part 8 retrieves the description data of the reference description character string in the word storage part 5 and outputs the retrieved data. Thereby, the reference description character string is displayed on the display device 7 through an output character string storage part 6. Thus, the reference description document can be formed.

Filed: 1989-04-15
Abstract: PURPOSE:To carry out a program including many branches at a high speed and with high efficiency by performing the branching process at a high speed with detection of coincidence between the value of a program counter and an address set on a table without executing each branch instruction included in the program. CONSTITUTION:The pre-branch and after-branch addresses are previously written into a pre-branch address table 7 and an after-branch address table 8 respectively. Then a branching destination address corresponding to a pre-branch address is selected out of the table 8 and set at a program counter 2 when the coincidence is obtained between an address shown by the counter 2 and the pre-branch address. Thus a branch process can be efficiently carried out. The processing time of the due branch is equal to only the time required for writing addresses to both tables 7 and 8. As a result, the executing time is shortened and the branch processing speed is increased.

Title: Method for accelerating formation of patina film and treating liquid
Inventor: OOYAMA KAZUYUKI
IPC: C23C22/68
Filed: 1986-04-25
Abstract: PURPOSE:To acceleratedly form a patina film having fine appearance and superior adhesion by coating the surface of copper with a treating liq. contg. an aqueous resin, a compound forming a complex salt with a copper ion, a compound causing a chelate bond to a copper ion, an alkali metallic salt and silica and by spraying water on the coated surface. CONSTITUTION:A treating liq. is prepd. by adding 10-300g/l (expressed in terms of solid matter) aqueous resin such as acrylic resin composition, 40-500g/l in total of a compound forming a complex salt with a copper ion, e.g., NH4OH, a compound causing a chelate bond to a copper ion, e.g., EDTA and an alkali metallic salt such as NaCl and 5-40g/l silica. The clean surface of copper or a copper alloy is coated with the treating liq. by 5-30g/m<2> (expressed in terms of a dry film) and the coated surface is forcedly dried. Water and/or steam is then sprayed on the coated surface in an atmosphere at ordinary temp.-80 deg.C at 1-12ml/m<2>/min rate for 5-120min. The coated surface may be exposed to an atmosphere at ordinary temp.-80 deg.C and >=90% relative humidity for 30-120min. Thus, the coated surface is allowed to uniformly develop a bluish green color in a relatively short time and finally the surface is dried.

Title: Signal processor of magnetic resolver
Inventor: SANO RITARO
IPC: G01D5/245
Filed: 1992-04-16
Abstract: PURPOSE:To make a rotational position detectable so accurately by seeking a phase drift value due to a variation in magnetic resolver winding resistance, and correcting a detection turning angle with this drift value. CONSTITUTION:Voltages Vco, Ven, Vso and Vsn generated in four-phase coils 1251-1256, 1261=1266, 1271-1276, 1281-1286 of a magnetic resolver are added and subtracted by two subtractor 35, 36 and an adder 37, and a phase difference between a specific frequency signal Vr obtained through a BPF 38 and an ac voltage out of a clock generator 30 or an exciting signal source is counted by a phase difference counter 41, thereby seeking a tuning angle pi of a rotor. Next, a phase drift value (Vadd-Vtheta1-1) to be produced by variations in the resisting value of the four-phase coils 1251-1286 is calculated by a drift value calculating means 46 from the phase difference between a reference signal Vtheta1-1 generated by regulating (42) phase and amplitude of the ac voltage of the generator 30 and a signal Vadd made up of adding (43) the voltages Vco, Vcpi, Vso and Vspi, thereby correcting the turning angle theta. With this constitution, even if the phase drift is generated in the detection signal as winding resistance is varied by a temperature change, it is corrected and thereby highly accurate position detection can be done in this way.

Title: Optical passive parts
Inventor: KUNIKANE TATSURO
IPC: G02B6/28
Filed: 1986-04-24
Abstract: PURPOSE:To obtain optical passive parts whose oscillating operation is stabilized and which are simplified in structure, small in size, and low in cost, by forming branched waveguides having different diameters and fitting a light emitting element to the thinner waveguide. CONSTITUTION:Branched waveguides are formed on a waveguide base board 6 made of silicon, etc., and their diameters are set at d1>=d2 (where, the d1 is the diameter of the thicker waveguide 7 and d2 is the diameter of the thinner waveguide 8). A photoreceptor element 2 is fitted to one end of the thicker waveguide 7 and an optical element 1 is connected with the thinner waveguide 8. Therefore, most of rays of light made incident on optical passive parts from the optical fiber 4 are coupled with the light receiving element 2, since d1>=d2. On the other hand, rays of light from the light emitting element 1 can be coupled with the optical fiber 4 at a low loss because of the relation d1>=d2. Thus the structure of optical passive parts is simplified and, as a result, the parts can be made smaller in size and lower in cost. At the same time, the reliability of the parts is improved.
