IPC: C07B39/00
Filed: 1989-08-08
Abstract: PURPOSE: To easily obtain a fluorinated aromatic compd. wherein F is introduced into an aromatic ring in good yield by allowing a metal salt to coexist in a phase transfer catalyst and, if necessary, reducing energy demand by nucleophilic exchange using KF in a solvent under a specific reaction condition.  
     CONSTITUTION: An aromatic chlorine and/or nitro compd. to be fluorinated such as 3,4-dichloro-nitrobenzene is used as a starting substance to be reacted with KF, if necessary, in a solvent such as tetramethylene sulfone in the presence of a phase transfer catalyst such as quaternary nitrogen compds. such as methyl-trioctyl-ammonium chloride, quaternary phosphorus compd., pyridinium salts or crown ethers and a metal salt such as salts of metals of 3-5 main groups and sub-groups of a periodic table of elements, for example, AlCl 3  at 10-25°C to obtain the objective compd. such as 3-chloro-4-fluoro-nitrobenzene. By the above mentioned method, the possibility of corrosion and decomposition reaction is reduced and the life of the catalyst is extended.

Title: Strobe system device coupling with camera
Inventor: HORINISHI KATSUMI
IPC: B82Y40/00
Filed: 1982-11-19
Abstract: PURPOSE:To adjust stepwise a signal voltage for controlling an aperture F value and to select the F value stepwise through one terminal by connecting the output of a decoder with a latch to a resistance selectively in an automatic dimming strobe for a camera. CONSTITUTION:The strobe device 1 is equipped with a logical arithmetic circuit 8, decoder circuit 11 with the latch, and light emission stop signal generating circuit 15. When a film speed and an aperture value are inputted from a terminal 9, a digital signal is outputted from output terminals F1-F3 together with a latch output L and a decoder 12 sends an output to a specific output terminal Di, so a voltage corresponding to a connected resistance among resistances 17- 24 is developed at a point 141 to obtain an F value signal. Further, the stationary output of outputs F1-F3 is supplied to the circuit 15 to control the proper level of the quantity of light. Thus, stepwise aperture control is performed by one output terminal.

IPC: H05K3/38
Filed: 1993-08-18
Abstract: PURPOSE:To enhance the reliability upon insulation by enhancing the bonding power of a bonding agent layer onto a plated resist layer and a plated layer as well as stiffening the insulation resistance of adjacent conductor patterns. CONSTITUTION:A bonding agent layer 3 in a semi-set state formed on the surface of a base material is to be roughened meeting the less strict requirements than the conventional ones. Next, a plated resist layer is formed on the roughened bonding agent layer. Later, the base material is thermal- pressed. At this time, the cavities in the anchor 2 formed in a bonding agent layer 3 are eliminated in the thermal-pressing step so that the bonding power of the bonding agent layer 3 onto the plated resist layer and a plated layer 1 may be enhanced. Furthermore, due to the water content, etc., hardly accumulated, the insulation resistance of adjacent conductor patterns can be stiffened to enhance the reliability upon insulation.

Title: Control method for electrification of glow plug
Inventor: HOTSUTA SEIKOU
IPC: F02P19/02
Filed: 1982-11-22
Abstract: PURPOSE:To uniformize the effective applying voltage of a glow plug without depending on a source voltage, by a method wherein, in the case of intermittent electrical connection, intermittent electrical connection is effected in response to a pulse signal, the duty ratio of which varies according to the voltage of the glow plug. CONSTITUTION:A waveform generated from a waveform generating circuit 16 is added to the non-inversion input terminal of a comparator 27. A voltage, being a source voltage divided by resistors 28 and 29, is applied to the inversion input terminal of the comparator 27. When the source voltage is high, a reference voltage increases, and when the source voltage is low, the reference voltage decreases. Thus, a time, for which the output of the comparator 27 generates a logic 1 signal, decreases when the source voltage is high, and increases when the source voltage is low. This causes uniformizing of the effective applying voltage of a glow plug without depending on the source voltage.

Title: High pressure discharge lamp
Inventor: WATABE KEIJI
IPC: H05B41/19
Filed: 1982-11-22
Abstract: PURPOSE:To produce a high pressure discharge lamp easy to restarting, by providing a light emission tube having a heater and a firing tube as a starter while connecting the high voltage generating terminal of firing tube with main electrode of light emission tube having no heater. CONSTITUTION:Upon direct connection of power source to the base of high pressure mercury lamp, discharge is first produced between the fixed electrode 18 and movable electrode 19 of firing tube 15 to flow current through a heater 14 thus to emit electrons. When the movable electrode 19 deforms due to heat through discharge, to contact both electrodes, discharge will stop to stop heating thus to separete the electrodes. Here the ballast 16 will produce surge voltage and since high voltage generating terminal 21 is connected to main electrode 2b, high potential side is applied to main electrode 2b. Consequently electrons emitted from the heater 14 is accelerated toward main electrode 2b to increase conductivity between main electrodes 2a, 2b thus to start discharge and light.

Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain a copper and a copper base alloy enabling soldering and excellent in direct bonding property without using flux by regulating surface roughness and oxide film thickness to in specific range. SOLUTION: The surface roughness of the copper and the copper base alloy is regulated to <=0.10 μm average roughness (Ra) in the center line and <=1.0 μm the max surface roughness (Rmax). By this method, in the joining of a lead and a bonding wire, the stable and intensive joined force can be obtd. The thickness of the oxide film is regulated to <=6 nm. This thickness is thin enough to execute the soldering without using the flux. In the case of exceeding this value, the joined strength and the soldering property between the lead and the wire are lowered. Further, it is desirable to incorporate 0.01-0.30 wt.% P and if necessary, 0.01-3.0 wt.% one or more kinds of Fe, Ni and Sn in the copper base alloy. The productivity at the time of melting and casting, heat resistance, further the bonding property and the soldering property can be improved.

IPC: H01L29/78
Filed: 1988-08-17
Abstract: PURPOSE:To reduce the overlapping of a gate and source.drain regions and thereby to decrease parasitic capacity by a method wherein a plasma substance is so deposited inside a gap provided in a semiconductor substrate that it will be thick in the upper section and thin in the lower section. CONSTITUTION:A gate oxide film 2 and a gate electrode polycrystalline silicon film 3 are formed on a semiconductor substrate and, on the silicon film 3, a nitride film 8 is formed by CVD. Anisotropic etching is then applied for the simultaneous fairing of the films 3 and 8. A photoresist film 9 is so formed that a narrow gap may be created in a later process between the film 9 and the silicon film 3. The photoresist film 9 is then subjected to baking, which results in a narrow gap 10. A plasma nitride film 11 is next formed. A plasma nitride, when supplied into such a gap as the narrow gap 10, is prompt in landing on the gap side walls but slow in reaching the gap bottom. This results in a plasma nitride film coating the gap side walls thick and covering the gap bottom thin.
