Title: Method for coloring copper
Inventor: MAEJIMA SEIJU
IPC: C23C22/63
Filed: 1989-05-30
Abstract: PURPOSE:To color the surface of copper from light interferential color into deep black color suitable for use in indoor and outdoor coppery ornaments, electrical parts, etc., by immersing copper in an aqueous solution of sodium polysulfide (Na2S2) and allowing sulfiding reaction to occur. CONSTITUTION:Copper is immersed in an aqueous solution of Na2S2, preferably, of 1-10wt.% concentration and held usually at about 20-30 deg.C, that is, the copper surface can be perfectly blackened within 5sec under the conditions, e.g. of 5wt.% Na2S2 concentration and 20-30 deg.C treating temp. After the blackening treatment, the alkaline residue is perfectly removed by means of water washing, hot water rinsing, etc., followed by drying. Further, since the above Na2S2 treatment solution can be easily neutralized, safety at the time of disposal can be increased. Moreover, the resulting blackened product is deep-black and is applicable to various uses as artistic and designed ornaments and machine parts, other than the above purposes.

Title: Selection epitaxial method
Inventor: AOE HIROYUKI
IPC: H01L21/205
Filed: 1985-06-20
Abstract: PURPOSE:To suppress auto-doping which extends from a high-concentration layer to an element region, by performing silicon-epitaxial growth over a silicon- exposed surface at low temperature, together with suppressing the generation of polycrystal silicon over SiO2 by the use of excited mixing gas. CONSTITUTION:After a mixed gas comprising a silicon compound gas and an inert gas is excited under a high-frequency electric field or high-frequency magnetic field, it is supplied over a silicon substrate on which an SiO2 film is selectively prepared, to make silicon epitaxially grow over the silicon-exposed part on the silicon substrate. Together with suppressing the generation of polycrystal silicon over SiO2, the epitaxial growth of silicon over the silicon- exposed surface can be performed at low temperature, and even if a high- concentration layer is formed on the surface of the silicon substrate, the auto- doping can be suppressed in the range extending from the high-concentration layer to the region for elements produced by the silicon epitaxial processing. Hence, as the operations of semiconductor elements formed over the region for elements do not become unstable, the elements are expected for stable operations.

Title: Image forming device
Inventor: IWAKURA YOSHIE
IPC: G03G15/16
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To stably transfer toner and electrostatically attract transfer material regardless of the kind of the transfer material by impressing voltage on a conductor layer so that charge may be accumulated in a pressuring conductive layer and bringing a dielectric layer into contact with a grounded roller through the transfer material. SOLUTION: A transfer drum 11 is provided with the pressuring conductive layer 27 between the dielectric layer 28 and the conductor layer 26. A power source part functioning as a voltage impressing means is connected to the layer 26. In order to electrostatically attract a transfer sheet P by the use of a ground roller 12, the charge is mainly generated by Paschen discharge and the injection of the charge. When the Paschen discharge is caused, the negative charge is accumulated on the surface of the layer 28 and the positive charge is accumulated on the transfer drum 11 side of the sheet P. In the case of the injection of the charge, the negative charge is accumulated on the drum 11 side at a nip part between the drum 11 and the roller 12 after the discharge is finished. Thus, the sheet P is electrostatically attracted to the drum 11.

Title: Electronic time sounding circuit
Inventor: KURODA MINORU
IPC: G04C21/02
Filed: 1978-10-31
Abstract: PURPOSE: To enable the clear discrimination of a last time announcing sound from other preceding ones, by strengthening the last sound and lengthening its attenuation time.  
     CONSTITUTION: When time comes, a number of sounds set in a preset counter C 2  is subtracted. When the content of the counter C 2  becomes zero at the generation of last time announcing sound, an OR circuit OR 1  produces an output to invert the output of a flip-flop F 3  through a register 21 and a NOR circuit NOR 10 . As a result, a sound making clock signal whose on-duty factor is shorter than its off-duty and which is passed through an AND gate AND 1  is inverted through a NOR circuit NOR 11  so that the on-duty is made longer than the off-duty. At the same time, a gate TG 1  of a damping circuit 16 is opened by the inversion of the flip-flop F 3  to disconnect a resistor Rg to lengthen the damping time of the circuit 16. This results in strengthening the last time announcing sound made by a time announcing sound generation circuit 18 and in lengthening the reverberation time of the sound. Therefore, the last sound can be clearly discriminated from other preceding ones.

Title: Pilot burner for surface combustion burner
Inventor: WATANABE SHIGEHIRO
IPC: F23Q9/00
Filed: 1985-06-20
Abstract: PURPOSE:To obtain a combustion flame stable at the time of ignition by inserting a pilot gas feed pipe into combustion assisting member made of sandy particles. CONSTITUTION:When a pilot burner is set to 'operation', a gaseous mixture of a fuel gas and air is supplied through an opening 4 of a pilot gas supply tube 5 to the combustion assisting member;. The combustion assisting member 1 is constituted of irregular polygonal particles. Since irregular clearance passages are formed on the entire surface of the combustion assisting member, the flow of the pilot gas is made uniform and the mixing of the fuel gas and air is promoted. The gaseous mixture which has reached the surface of the combustion assisting member is rectified by a conductive member (b), ignited by the discharge from a main gas feed tube 3 to form a flame on the surface of the combustion assisting member. The gaseous mixture which has been fed from a main gas feed tube 3 reaches the surface of the combustion assisting member, and is ignited by a pilot flame, thus excellent combustion is carried out over the entire outer surface of the combustion assisting member. However, since the pilot gas feed tube 5 is inserted within the combustion assisting member 1, an excellent pilot flame is constantly formed on the outer surface of the conductive member even when the main combustion is started or stopped.

Filed: 1990-05-25
Abstract: PURPOSE:To adjust an output level with respect to the dispersion in light quantity or the like by providing a resistance selection circuit selecting and connecting a resistor for sensitivity adjustment to an outside of an IC chip. CONSTITUTION:A light receiving element receives a light reflected in an original from a light from a light emitting element and the received light is converted into a voltage signal by a current / voltage conversion circuit. Each output signal of the conversion circuit is inputted to an operational amplifier 6 for analog output amplification. Pads P1 - P4 are used for selecting resistors for sensitivity adjustment, pads P5 - P7 are used respectively for GND, VSS, VDD, a pad P1 is used for input and a pad P0 is used for output. The output level of the output pad P0 is adjusted by varying a resistor R1. Since the resistance of resistors R1a, R1b, R1c, R1d is different from each other, various resistance is selected by the parallel connection of some combinations and the output level is stepwise adjusted. Thus, the variation in the output level is decreased and stabilized.

Title: Manufacture of oxide magnetic thin film
Inventor: TAKAGAKI ATSUSUKE
IPC: G11B5/85
Filed: 1983-07-27
Abstract: PURPOSE:To facilitate the use of the maximum power of a source for sputtering and simplify the process and improve the film formation efficiency by utilizing effectively a preparatory sputtering under the pressure not higher than a normal partial pressure of oxygen with which an oxide film can be removed. CONSTITUTION:Iron or alloy whose main component is iron is used for a target and an Fe3O4 film is formed on a substrate maintained at 150-300 deg.C by sputtering in an atmosphere of oxygen-vapor. Then the film is subjected to low temperature oxidization in the atmosphere and an oxide magnetic thin film composed of gamma-Fe2O3 is obtained. In this composition, vapor is introduced onto the target surface while a partial pressure of oxygen with which an oxide film can be removed is maintained and reactive sputtering is performed under this condition. With this constitution, a margin of vapor is very wide and workability is not influenced by the introduction of this method and the maximum power can be used from the beginning of the sputtering.

Title: Differential amplifier
Inventor: FUNAHASHI MASAHIRO
IPC: H03F3/45
Filed: 1988-06-01
Abstract: PURPOSE:To decrease a current offset of a couple of transistors(TRs) even if there is dispersion in the current amplification factor beta of the TRs by connecting a current mirror circuit to a differential connection circuit as an active load and adding two TRs to a conventional circuit provided with TRs as an output stage. CONSTITUTION:TRs Q11, Q12 are added to a conventional circuit. Since a base current of the TR Q11 equal to the base current of the TR Q7 flows from the emitter of the TR Q7 by giving a collector current equal to that of the TR Q7 to the TR Q11, the collector current of the TRs Q7, Q8 is identical and each base current is made equal to each other. Thus, the current offset of the TRs Q1, Q2 is further decreased. Moreover, since a nearly equal current amplification factor beta of plural TRs formed in one and same tap in an integrated semiconductor device is obtained, the current amplification factor of the TRs Q7, Q8, Q11 is always equal to one another and the effect of reducing the current offset is not lost even with the dispersion in the current amplification factor beta.
